Description

  The present invention relates to a technique using a coding pattern readable by an electronic pen.

  In recent years, electronic pens that digitize written information have been developed, and “Anot pen” developed by Swedish company Anoto is known as a representative one. Anotopen is used with dedicated paper on which a predetermined dot pattern is printed. In addition to the usual ink cartridge for writing characters, etc., the anotopen has a small camera for capturing the dot pattern printed on the dedicated paper and the position coordinates on the dedicated paper from the captured dot pattern. A processor for calculating and a data communication unit for transmitting the calculated position coordinates and the like to an external device are mounted. When the user writes characters on the special paper with an anotopen or puts a check mark on the image designed on the special paper, the small camera captures the dot pattern printed on the special paper as the pen moves. The entry information such as characters and images written by the user is recognized from the continuous position coordinates calculated by the processor. Then, this entry information is transmitted from the Anotopen by the data communication unit to a nearby terminal device such as a personal computer or a mobile phone (for example, see Patent Document 1).

  Patent Documents 2 and 3 disclose a system in which a dot pattern is stacked on an optical touch panel, and input using an electronic pen and touch panel input using a finger are possible. Non-Patent Document 1 has a configuration in which a liquid crystal is inserted and an electromagnetic induction type tablet is arranged at the bottom and a resistive film type touch panel is arranged at the top, allowing both input with an electronic pen and input with a finger. A touch panel is disclosed.

  Further, in Patent Document 4, the position designation and comment on the car navigation electronic map are written on the dedicated sheet on which the dot pattern and the map are superimposed and printed by writing the position designation on the map with the electronic pen and the comment. A technique for registering is disclosed. Further, in Patent Document 5, a scanner is applied to a paper on which a dot pattern and a map are superimposed and printed to display a peripheral map at a specified position on a computer device. The map displayed on the computer device can be enlarged / reduced or moved by applying the scanner to the buttons such as “Enlarge”, “Reduce”, “Up”, “Left”, “Right”, “Down”. The technique to let it be disclosed is disclosed.

  Hereinafter, a first embodiment and a second embodiment, which are embodiments of the present invention, will be described in order with reference to the drawings.

<First Embodiment>
First, a first embodiment according to the present invention will be described.

[Configuration of input system]
FIG. 1 shows a configuration of an input system according to the first embodiment. As shown in FIG. 1, the input system includes an electronic pen 1 used by a user, a computer device 2 that receives and processes information from the electronic pen 1 and the display device 3, and a display device 3 connected to the computer device 2. And a map information providing server 4 for transmitting the map information to the computer device 2 via a communication network (network). As will be described later, the input system performs predetermined processing in accordance with input based on the electronic pen 1 (also referred to as “electronic pen input”) and input based on the touch panel 34 (also referred to as “touch panel input”). .

(Display device)
FIG. 2 shows a configuration of the display device 3 according to the first embodiment. As shown in FIG. 2, the display device 3 has a multilayer structure, and in order from the upper layer, a dot pattern overlayer (dot pattern forming layer) (also simply referred to as “DOL”) 30, a touch panel 34, and a display panel 35.

  The DOL 30 is disposed on the uppermost layer of the display device 3. The DOL 30 is an ink containing a material (titanium oxide, cholesteric liquid crystal, infrared reflective pigment, etc.) that reflects infrared rays so that it can be read by the electronic pen 1 on a base film 33 that is a transparent resin substrate such as polyethylene terephthalate. In this way, dots 32 of a dot pattern (coded pattern) are printed, and the layer structure is further protected by a protective layer 31 such as a transparent EB cured resin. Here, the dot pattern is printed with a material that reflects infrared rays. Even when visible light of various colors is radiated from the display panel 35 under the DOL 30, the dot pattern is formed with high contrast by the electronic pen 1. This is because it is desirable for recognition. The DOL 30 is an example of the “coded pattern layer” in the present invention.

  A touch panel 34 is bonded to the back surface of the DOL 30. The touch panel 34 is, for example, a resistive touch panel, an ultrasonic touch panel, an optical touch panel, a capacitive touch panel, or the like, and detects a contact position on the DOL 30. Hereinafter, among the regions on the DOL 30 where the touch panel 34 detects contact, a group of connected regions is referred to as a “contact region”, and the area of each contact region is also referred to as a “contact area q”. As shown in FIG. 2, the contact area q when the electronic pen 1 contacts the DOL 30 is smaller than the contact area q when the user's finger contacts the DOL 30.

  The configuration of the display device 3 to which the present invention is applicable is not limited to the configuration of FIG. Instead of this, the display device 3 is provided with an infrared reflective layer between the dot pattern and the base film 33 or between the base film 33 and the touch panel 34, and the dot pattern further absorbs carbon that absorbs infrared rays. The configuration may be such that printing is performed with the contained ink.

(Dot pattern)
Next, a dot pattern (coded pattern) will be described with reference to FIGS. The dot pattern is based on the system of Anoto. FIG. 3 is a diagram for explaining the relationship between dots in a dot pattern and values to which the dots are converted. As shown in FIG. 3, each dot of the dot pattern is associated with a predetermined value depending on its position. That is, each dot is associated with a value of 0 to 3 depending on which direction the top, bottom, left, or right is shifted from the reference position of the virtual grid (the intersection of the vertical and horizontal lines). The value of each dot can be further converted into a first bit value for the X coordinate and a second bit value for the Y coordinate. The position coordinates on the DOL 30 are determined by the combination of the information thus associated.

  FIG. 4A shows an arrangement of a certain dot pattern. As shown in FIG. 4A, 6 × 6 dots are arranged in a range of about 2 mm in length and width so that a unique pattern can be obtained no matter where 6 × 6 dots are taken on DOL 30. . The dot pattern formed by these 36 dots holds position coordinates (for example, on which position on the DOL 30 the dot pattern is located). FIG. 4B is a diagram in which each dot shown in FIG. 4A is converted into a value associated with the regularity shown in FIG. 3 according to the shift direction from the reference position of the lattice. This conversion is performed by the electronic pen 1 that captures an image of a dot pattern.

(Electronic pen)
Next, the electronic pen 1 will be described with reference to FIG. FIG. 5 is a schematic view showing the structure of the electronic pen 1. As shown in FIG. 5, the electronic pen 1 includes a pen unit 104, an LED 105, a CMOS camera 106, a pressure sensor 107, a processor 108 including a CPU, a memory 109 such as a ROM and a RAM, A communication unit 111 including a real-time clock 110, an antenna, and the like, and a battery 112 are provided. The tip of the pen unit 104 is a pen point unit 103, and the user touches the pen point unit 103 of the electronic pen 1 on the DOL 30 and enters a stroke (handwritten stroke). Here, the pen tip portion 103 of the electronic pen 1 that first contacts the DOL 30 is referred to as pen-down, and the pen tip portion 103 leaving the contacted (contacted) state is referred to as pen-up. A trajectory written between the pen-down and pen-up of the electronic pen 1 is one stroke, and characters, figures, etc. are composed of one or a plurality of strokes.

  The battery 112 is for supplying power to each component in the electronic pen 1, and is configured to turn on / off the power of the electronic pen 1 itself by, for example, detaching a cap (not shown) of the electronic pen 1. You may let them. The real time clock 110 transmits time information indicating the current time (time stamp) and supplies the time information to the processor 108. The pressure sensor 107 detects the pressure applied through the pen unit 104 from the pen point unit 103 when the user writes or taps a character or mark on the DOL 30 with the electronic pen 1, that is, the writing pressure, and the value is detected by the processor. To 108.

  The processor 108 switches on / off the switches of the LED 105 and the CMOS camera 106 based on the writing pressure data supplied from the pressure sensor 107. That is, when a user writes a character or the like on the DOL 30 with the electronic pen 1, the pen pressure is applied to the pen tip portion 103, and when the pressure sensor 107 detects a writing pressure higher than a predetermined value, the processor 108 It is determined that entry has started, and the LED 105 and the CMOS camera 106 are operated. Then, the communication unit 111 associates pen-down information detected by the pressure sensor 107 with identification information (hereinafter referred to as “pen ID”) of the electronic pen 1 described later, and transmits the information to the computer apparatus 2 as entry information. To do. When the user finishes entering one stroke and releases the electronic pen 1 from the DOL 30, the pressure sensor 107 detects pen-up because no writing pressure exceeding a predetermined value is detected. Then, the communication unit 111 associates the pen-up information detected by the pressure sensor 107 with the pen ID, and transmits it to the computer apparatus 2 as entry information.

  The LED 105 and the CMOS camera 106 are attached near the pen tip portion 103 of the electronic pen 1, and an opening 102 is formed in a portion of the housing 101 that faces the LED 105 and the CMOS camera 106. The LED 105 illuminates infrared rays toward the vicinity of the pen tip portion 103 on the DOL 30. The region is slightly deviated from the position where the pen tip 103 contacts the DOL 30. The CMOS camera 106 is provided with an infrared filter that transmits infrared rays and blocks non-infrared rays. The CMOS camera 106 captures a dot pattern in an area illuminated by the LED 105 and processes image data of the dot pattern as a processor. 108. Here, since the ink material of dots reflects infrared rays, the infrared rays irradiated by the LED 105 are reflected by the dots. Therefore, the dot portion has a relatively large amount of infrared reflection, and the portion other than the dot has a relatively small amount of infrared reflection. By photographing with the CMOS camera 106, a dot area and other areas can be distinguished by providing a threshold value based on the difference in the amount of reflected infrared light. Note that the shooting area by the CMOS camera 106 is a range including a size of about 2 mm × about 2 mm as shown in FIG. 4A, and the shooting by the CMOS camera 106 is performed at regular intervals of about 50 to 100 times per second. Is called. Further, the CMOS camera 106 has a sufficient depth of field in order to photograph dots clearly.

  The processor 108 performs X and Y coordinates (hereinafter simply referred to as “coordinate data”) in the DOL 30 of the stroke (handwriting) to be entered by the user from the dot pattern of the image data supplied by the CMOS camera 106 during the user entry. It is also called “coordinate information”). That is, the processor 108 converts the image data of the dot pattern as shown in FIG. 4 (a) supplied by the CMOS camera 106 into the data array shown in FIG. 4 (b). The data is converted into a Y coordinate bit value, and X and Y coordinate data are calculated from the data array by a predetermined calculation method. The processor 108 has a rotation correction processing function for correcting the arrangement of dots on the image due to the angle of the electronic pen 1 facing the dot pattern. Then, the processor 108 associates the current time (time stamp: entered time information) transmitted from the real-time clock 110, writing pressure data, and X and Y coordinate data. Hereinafter, these associated data are collectively referred to as “coordinate attribute information”. Since the 6 × 6 dot pattern in the DOL 30 does not overlap in the DOL 30, when the user enters characters or the like with the electronic pen 1, the processor 108 determines which position in the DOL 30 the entered position corresponds to. It can be specified by coordinate calculation.

  The memory 109 stores property information such as a pen ID such as “pen01” for identifying the electronic pen 1, a pen manufacturer number, and a pen software version. Then, the communication unit 111 associates the pen ID, time information (time stamp), writing pressure data, and X and Y coordinate data, and transmits them to the computer apparatus 2 as entry information. Transmission to the computer apparatus 2 by the communication unit 111 is performed immediately and sequentially by wireless transmission such as Bluetooth (registered trademark). Here, one or a plurality of coordinate attribute information generated between the pen-down and pen-up of the electronic pen 1 and transmitted to the computer device 2 is stored as stroke information by the computer device 2. In other words, one stroke is made up of one or a plurality of X, Y coordinates (coordinate points), and the computer apparatus 2 can use one or a plurality of pieces constituting one stroke based on the pen-down information and the pen-up information. Recognize coordinate attribute information. As described above, a set of coordinate attribute information generated by the electronic pen 1 when the user enters one stroke is referred to as “stroke information”. The pen tip 103 is made of a material such as plastic or stainless steel. The pen tip portion 103 does not have ink, and transmits pen pressure to the pressure sensor 107 via the pen portion 104.

  The electronic pen 1 may be used as a ballpoint pen by loading an ink cartridge in the pen unit 104. In addition, the electronic pen 1 transmits entry information to the computer apparatus 2 by wireless transmission. However, the electronic pen 1 is not limited thereto, and may be connected to the computer apparatus 2 by wire and transmit entry information to the computer apparatus 2 by wire transmission. .

  Preferably, when the CMOS camera 106 recognizes the dot pattern, the electronic pen 1 determines whether the dot pattern is formed of an infrared reflecting material or an infrared absorbing material, and based on the determination. The dot pattern reading program may be switched. Specifically, the electronic pen 1 first performs a binarization process on the image captured by the CMOS camera 106 using a predetermined threshold, and the infrared reflection region and the infrared absorption from the binarized image. The area is discriminated, and the magnitude relation between the area of the infrared reflection area and the area of the infrared absorption area is compared. The electronic pen 1 performs a negative / positive inversion process on the binarized image when the infrared absorption area is larger than the infrared reflection area, and performs a negative / positive inversion process when the negative / positive inversion process is performed. The dot pattern is recognized based on the obtained image, and when the negative / positive inversion process is not performed, the dot pattern is recognized based on the binarized image. Thereby, it is possible to appropriately recognize both the dot pattern printed with the infrared absorbing ink and the dot pattern printed with the infrared reflective ink.

(Computer device)
Next, the computer apparatus 2 will be described again with reference to FIG. The computer device 2 includes, as hardware, an antenna device capable of data communication with the electronic pen 1, a processor such as a CPU, a memory such as a ROM and a RAM, a mouse and a keyboard. The computer device 2 may be configured by a PC (personal computer) including the display device 3 as a display unit, a tablet PC such as iPad (registered trademark), a PDA (Personal Data Assistance), or the like. As shown in FIG. 1, the computer apparatus 2 is functionally configured to receive map information from the map information providing server 4 via the input means 21, such as a mouse or a keyboard, the receiving means 22, the processing means 24, the storage means 25, and the network. Is provided. Then, the computer device 2 is predetermined based on the entry information received from the electronic pen 1, the input information received from the touch panel 34 (also referred to as “touch panel input information”), and the map information received from the map information providing server 4. The process is performed.

  The receiving means 22 is constituted by an antenna receiving circuit or the like, receives entry information from the electronic pen 1 and transmits it to the processing means 24. Further, the computer apparatus 2 converts the coordinate system (also referred to as “DOL coordinate system”) related to the dot pattern formed on the DOL 30 to the coordinate system (also referred to as “display coordinate system”) related to the display panel 35. Calibration processing functions for obtaining the first coordinate conversion function and the second coordinate conversion function for converting the coordinate system (also referred to as “touch panel coordinate system”) applied to the touch panel 34 to the display coordinate system. ing. Furthermore, when the computer apparatus 2 receives the data of the DOL coordinate system using the first coordinate conversion function obtained by the calibration process, the computer apparatus 2 converts the data into the data of the display coordinate system and draws a stroke. When touch panel coordinate system data is received using a function for performing a predetermined process and the second coordinate conversion function, the data is converted into display coordinate system data, and predetermined processes such as icon selection are performed. It has a function.

  The processing means 24 is constituted by a processor such as a CPU and controls the entire computer apparatus 2. Specifically, the processing unit 24 transmits the image signal generated by the computer apparatus 2 to the display panel 35 and displays an image corresponding to the image signal. For example, the browser display control means 240 of the processing means 24 receives map information for displaying a map on the WEB browser from the map information providing server 4 via the interface 28, and a map such as Google Map (registered trademark). A screen including a display area for displaying and an operation area thereof (also referred to as a “map application screen”) is displayed on the WEB browser. Here, as will be described later, the map application screen allows the user to display a map of a desired place in the display area, or to specify an arbitrary position on the map displayed in the display area, and to relate to the position. This is a screen for writing notes. The browser display control means 240 performs display control of this map application screen by using, for example, Ajax (Asynchronous JavaScript + XML) technology. The processing unit 24 stores the first coordinate conversion function and the second coordinate conversion function obtained by the calibration processing function in the storage unit 25.

  When the computer device 2 receives the entry information from the electronic pen 1, the first coordinate conversion means 241 of the processing means 24 converts the coordinate data included in the entry information, which is DOL coordinate system data, into a first coordinate conversion function. To convert to display coordinate system data. Then, the processing unit 24 recognizes that the position written by the electronic pen 1 is the dot pattern of the DOL 30 based on the converted coordinate data. The processing unit 24 stores the converted coordinate data in the storage unit 25, displays a stroke based on the converted coordinate data or the like on the display panel 35, or displays a folder or application at a position corresponding to the stroke. If the icon is displayed, processing such as selection of the icon is performed. In addition, when the processing unit 24 determines that the corresponding position of the stroke is on the map application screen, the processing unit 24 executes processing described in the section [Map application screen] described later.

  When the computer apparatus 2 receives touch panel input information from the touch panel 34, the second coordinate conversion unit 242 of the processing unit 24 uses the second coordinate conversion function to convert the coordinate data of the touch panel coordinate system indicated by the touch panel input information, using the second coordinate conversion function. Convert to display coordinate system data. Then, when an icon such as a folder or an application is displayed on the coordinate data after conversion in the image being displayed on the display panel 35, the processing means 24 performs processing such as selection of the icon. In addition, when the processing unit 24 determines that the position corresponding to the coordinate data after conversion is on the map application screen, the processing unit 24 performs processing described in the section [Map application screen] described later.

When the touch panel function switching unit 243 of the processing unit 24 determines that the electronic pen input is performed based on the contact area q detected by the touch panel 34 and the presence / absence of reception of the entry information from the electronic pen 1, The input function of the touch panel 34 is turned off. Specifically, the touch panel function switching unit 243 specifies the contact area based on the coordinate information indicated by the touch panel input information, obtains the contact area q, the contact area q is greater than the threshold “Q1”, and the threshold “Q2”. If the entry information is received from the electronic pen 1, it is determined that the input is made by the electronic pen 1, and the input function of the touch panel 34 is turned off. In other words, when the following condition A is satisfied and entry information is received from the electronic pen 1, the touch panel function switching unit 243 determines that the input is electronic pen input and turns off the input function of the touch panel 34. .
Q1 <q <Q2 Condition (A)

  Here, the threshold value Q1 is set to a value smaller than the lower limit value that can be taken by the contact area q of the electronic pen 1, and the threshold value Q2 is set to a value that is larger than the upper limit value that can be taken by the contact area q of the electronic pen 1. .

  The relationship between the contact area q and the threshold values Q1 and Q2 will be described in more detail with reference to FIG. 6A shows the electronic pen 1 and the hand holding the electronic pen 1 during the pen-down, and FIG. 6B shows the DOL 30 of the pen tip portion 103 of the electronic pen 1 corresponding to FIG. 6A. An example of the upper contact area (also referred to as “pen tip contact area”) and the contact area on the side DOL 30 of the hand (also referred to as “hand side contact area”) is shown in FIG. An example of a contact area (also referred to as “fingertip contact area”) on the DOL 30 of the fingertip when performing touch panel input by bringing the fingertip into contact with the DOL30 is shown.

  As shown in FIGS. 6B and 6C, the pen tip contact area is the smallest among the pen tip contact area, the fingertip contact area, and the hand side contact area, and the hand side contact area is the largest. It becomes an area. Therefore, the threshold value Q2 is set to a value larger than the contact area q of the electronic pen 1 and smaller than the contact area q of the finger. Accordingly, the touch panel function switching unit 243 can determine whether or not the contact area detected based on the contact area q is a pen tip contact area, and can determine whether or not the input is an electronic pen. Note that the fingertip contact area and the hand side contact area should be of an average size.

In addition, when the contact area q is equal to or greater than the threshold value Q2, the processing unit 24 determines whether the contact area is the fingertip contact area based on the contact area q or the like and determines that the contact area is the fingertip contact area. Process as touch panel input. Specifically, when the contact area q is larger than the threshold value “Q3” and smaller than the threshold value “Q4” and the designated position can be specified based on the contact area, the processing unit 24 determines that the contact area is Judged to be the fingertip contact area. That is, the processing unit 24 determines that the contact area is the fingertip contact area when the following condition B is satisfied and the touch panel input instruction position can be specified.
Q3 <q <Q4 Condition (B)

  Here, the threshold value Q3 is set to a value that is larger than the threshold value Q2 and smaller than the lower limit value that can be taken by the contact area q of the user's fingertip, and the threshold value Q4 is a value that can be taken by the contact area q of the user's fingertip. Is set to a value that is larger than the upper limit value and smaller than the possible value of the contact area q of the hand side contact area. In addition, as the indicated position, the processing unit 24 obtains the center position or the gravity center position of the detected contact area, and determines whether or not the contact area falls within a circular area having a predetermined radius centered on the center position or the gravity center position. To identify. When the contact area falls within the circle area, the processing unit 24 determines that the contact area is a substantially circular fingertip contact area and is the designated position, and the contact area does not fit within the circle area. It is determined that the contact area has a thin rod shape or other irregular shape, and the indicated position cannot be specified.

  The storage unit 25 is configured by a memory such as a ROM or a RAM. The storage means 25 stores the first coordinate conversion function and the second coordinate conversion function. In addition, the storage unit 25 stores the entry information received from the electronic pen 1 for each pen ID or the predetermined data generated by the execution of the program according to the processing instruction of the processing unit 24.

(Map information server)
Next, the map information providing server 4 will be described. The map information providing server 4 includes, as hardware, a communication device capable of data communication with the computer device 2, a processor such as a CPU, a memory such as a ROM and a RAM, and the like. The map information providing server 4 holds map information in a memory. Then, the map information providing server 4 transmits map information necessary for displaying a map on the map application screen to the computer device 2 in response to a request from the computer device 2.

[Map app screen]
Next, a specific example of the map application screen displayed on the display device 3 and a process executed by the processing unit 24 of the computer device 2 in accordance with each user operation will be specifically described.

  First, the map application screen displayed on the display device 3 will be described with reference to FIG. FIG. 7 shows a display example of the map application screen. As shown in FIG. 7, the map application screen 50 is displayed on a WEB browser and includes a position designation area 51, a write designation area 52, and a display area 53. The position designation area 51 is an area selected by the finger or the electronic pen 1 when the user designates a position in the map displayed in the display area 53. The writing designation area 52 is an area selected by the finger or the electronic pen 1 when performing memo writing (writing) related to the designated position. The position designation area 51 and the write designation area 52 are operation areas for designating operations on the display area 53, and are examples of the “first area” in the present invention. The display area 53 is an area for displaying a map based on the map information provided by the map information providing server 4. As will be described later, in the map displayed in the display area 53, the display location and the scale ratio (that is, the enlargement / reduction ratio) are appropriately changed according to the operation of the user's finger or the electronic pen 1. At the same time, the position is designated and written according to the operation with the electronic pen 1. The display area 53 is an example of the “second area” in the present invention.

  Next, processing executed by the processing unit 24 in accordance with each operation of the user will be described with reference to FIGS. 7 to 10 are examples of the map application screen 50 corresponding to each operation of the user.

  First, for example, as shown in FIG. 7, the user performs an operation of sliding the map display (also referred to as “map moving operation”) by moving the finger while touching the display area 53 with the finger. . In this case, the processing unit 24 converts the coordinate data of the touch panel coordinate system included in the touch panel input information transmitted from the touch panel 34 into the data of the display coordinate system by the second coordinate conversion unit 242 using the second coordinate conversion function. To do. Then, the processing means 24 detects the trajectory of the finger moved on the display area 53 based on the converted coordinate data, and changes the latitude and longitude ranges displayed as a map in the display area 53 accordingly. .

  The user may perform the map moving operation by drawing one stroke in the display area 53 with the electronic pen 1 instead of the finger. In this case, the processing unit 24 uses the first coordinate conversion function stored in the storage unit 25 to convert the DOL coordinate system coordinate information included in the entry information transmitted from the electronic pen 1 into the display coordinate system coordinate information. Convert to Then, the processing means 24 detects the locus of the electronic pen 1 moved on the display area 53 based on the converted coordinate data, and according to this, the latitude and longitude ranges to be displayed as a map in the display area 53 are determined. change.

  Next, as shown in FIG. 8, the user taps the position designation area 51 displayed as “position designation” with the electronic pen 1. In this case, the processing means 24 detects that an electronic pen input has been made on the position designation area 51 based on the entry information transmitted from the electronic pen 1, and lights the position designation area 51 in a specific color. This clearly informs the user that the position can be specified on the display area 53. Hereinafter, this state is also expressed as “a state where the position designation area 51 is selected”. The user may select the position designation area 51 by touching the position designation area 51 with a finger instead of the electronic pen 1. In this case, the processing means 24 detects that a touch panel input has been made on the position designation area 51 based on the touch panel input information transmitted from the touch panel 34 and lights the position designation area 51 in a specific color.

  Next, as shown in FIG. 8, the user performs an operation (also referred to as “position specifying operation”) for specifying a position by tapping with the electronic pen 1 on the map displayed in the display area 53. In this case, the processing means 24 receives the entry information transmitted from the electronic pen 1, and the first coordinate conversion means 241 of the processing means 24 receives the coordinate data included in the entry information, which is DOL coordinate system data. The first coordinate conversion function is used to convert the data into the display coordinate system. Then, the processing unit 24 recognizes that the position tapped by the electronic pen 1 is a dot pattern arranged in the display area 53 based on the converted coordinate data. Then, the processing unit 24 calculates the latitude and longitude on the map based on the position indicated by the dot pattern on the specified display area 53. Then, the processing unit 24 stores the latitude and longitude information (also referred to as “latitude / longitude information”) of the specified position in the storage unit 25 and, as shown in FIG. A position designation mark 55 as a mark is displayed. The latitude / longitude information is an example of “position information” in the present invention.

  Even when the position designation area 51 is lit, when the processing means 24 detects a map moving operation with a finger based on the touch panel input information, the processing means 24 displays it in the display area 53 according to the operation. Slide the displayed map display. Similarly, when the processing unit 24 detects an operation for enlarging or reducing a map displayed in the display area 53 described later (also referred to as a “map enlarging / reducing operation”) based on the touch panel input information, In response to the operation, the display of the map displayed in the display area 53 is enlarged or reduced. On the other hand, the processing means 24 does not accept a map moving operation with the electronic pen 1 and a position specifying operation with a finger when the position specifying area 51 is lit. That is, when the position designation area 51 is lit, the processing means 24 treats the electronic pen input to the display area 53 as an input by the position designation operation, and handles the touch panel input to the display area 53 as a map moving operation or Handled as input by map scaling operation. As described above, the processing unit 24 executes different processes for the electronic pen input and the touch panel input for the display area 53.

  Next, as shown in FIG. 9, the user taps the writing designation area 52 displayed as “memo writing” with the electronic pen 1. In this case, the processing means 24 detects that an electronic pen input has been made on the write designation area 52 based on the entry information transmitted from the electronic pen 1, turns off the position designation area 51, and turns off the write designation area 52. Is lit in a predetermined color. Hereinafter, this state is also expressed as “a state where the write designation area 52 is selected”. Note that the user may select the writing designation area 52 by touching the writing designation area 52 with a finger instead of the electronic pen 1. In this case, the processing means 24 detects that touch panel input has been made on the write designation area 52 based on the touch panel input information transmitted from the touch panel 34, and lights the write designation area 52 in a specific color.

  Next, as shown in FIG. 9, the user performs an operation (also referred to as “writing operation”) for writing a memo related to the designated position on the display area 53 with the electronic pen 1. Here, the user enters “fishing pit” on the display area 53 with the electronic pen 1. In this case, the first coordinate conversion unit 241 of the processing unit 24 converts the coordinate data included in the entry information, which is DOL coordinate system data, into display coordinate system data using the first coordinate conversion function. . Then, the processing unit 24 recognizes that the position written by the electronic pen 1 is a dot pattern on the display area 53 of the DOL 30 based on the converted coordinate data. Then, the processing means 24 displays a stroke based on the converted coordinate data on the display area 53. In addition, the processing unit 24 associates information (also referred to as “write information”) necessary for displaying the stroke described above with the latitude / longitude information specified by the position designation operation, and stores the information in the storage unit 25. Thereafter, when the processing means 24 displays a map including the point where the position has been specified on the display area 53, the processing means 24 puts the memo characters entered by the writing operation together with the position specifying mark 55 on the map. indicate.

  Preferably, the processing means 24 displays the position designation mark 55 and the character for the memo by, for example, displaying the memo character “fishing pit” entered by the writing operation in a balloon pointing to the position designation mark 55. The correspondence with is displayed more clearly. Note that the processing unit 24 may dynamically generate the balloon so as to include all the strokes during the entry of the stroke by the writing operation.

  When the user designates another position on the map displayed in the display area 53, the user touches the position designation area 51 displayed as “position designation” with the finger or taps with the electronic pen 1. Then, the processing means 24 turns off the write designation area 52 and turns on the position designation area 51 with a predetermined color. Alternatively, when ending the “memo writing” without designating another position, the user touches the writing designation area 52 with the finger again or taps with the electronic pen 1. In this case, the processing means 24 turns off the write designation area 52.

  Even when the writing designation area 52 is lit, when the processing unit 24 detects a map moving operation or a map enlargement / reduction operation with a finger based on the touch panel input information, the processing unit 24 responds to the operation. The map displayed in the display area 53 is moved, enlarged or reduced. On the other hand, the processing means 24 does not accept a map moving operation with the electronic pen 1 and a writing operation with a finger when the writing designation area 52 is lit. As described above, the processing unit 24 executes different processes for the electronic pen input and the touch panel input on the display area 53 when the writing designation area 52 is lit.

Further, as shown in FIG. 10, the user enlarges the map displayed in the display area 53 regardless of whether the position designation area 51 is turned off or turned on and whether the writing designation area 52 is turned off or turned on. In this case, the two fingers are moved away from each other while touching the display area 53. In this case, based on the touch panel input information, the processing means 24 detects that the two detected contact areas have moved on the display area 53 in directions away from each other, and is displayed on the display area 53 according to the amount of movement. Magnify the map display. Similarly, when the user reduces the map displayed in the display area 53, the user moves the two fingers in a direction approaching each other while touching the two fingers on the display area 53. In this case, based on the touch panel input information, the processing unit 24 detects that the two detected contact areas have moved on the display area 53 in a direction approaching each other, and is displayed on the display area 53 according to the amount of movement. Reduce the map display.
[Processing flow]
Next, a processing flow based on touch panel input detection in the input system of the first embodiment will be described. The processing flow shown in FIG. 11 is repeatedly executed every time the computer apparatus 2 receives touch panel input information from the touch panel 34, and is executed for each contact area generated by touch panel input. Therefore, when a plurality of touch panel inputs are detected, the process shown in FIG. 11 is performed for each touch panel input.

  When the touch panel 34 detects a contact on the DOL 30, the touch panel 34 transmits touch panel input information to the computer apparatus 2. Thereby, the processing means 24 of the computer apparatus 2 detects that there was a touch panel input (step S101). Next, the processing means 24 calculates the contact area q for each of the detected one or more contact areas based on the coordinate data of the touch panel coordinate system indicated by the touch panel input information received from the touch panel 34, and each contact area q Is satisfied whether the condition A (Q1 <q <Q2) is satisfied, the condition B (Q3 <q <Q4) is satisfied, or neither of the conditions A and B is satisfied (step S102).

  If it is determined that the condition A is satisfied (step S102: condition A), the processing unit 24 determines whether entry information is received from the electronic pen 1 (step S103). Accordingly, the processing unit 24 determines whether or not the detection of the touch panel input in step S201 is based on the contact on the DOL 30 of the electronic pen 1 during the electronic pen input. Note that when the electronic pen 1 is downed, the touch panel input detection timing is earlier than the timing at which the computer apparatus 2 receives the entry information due to the time for the electronic pen 1 to generate the entry information. . Therefore, the processing means 24 determines whether or not entry information is received from the electronic pen 1 for a predetermined time width corresponding to the above-described timing difference (time lag) after the execution of step S101.

  If it is determined that the entry information has been received (step S103; Yes), the processing unit 24 causes the storage unit 25 to store the entry information for each pen ID (step S104). Next, the processing means 24 determines whether or not the input function of the touch panel 34 has already been turned off (step S105). When it is determined that the input function of the touch panel 34 is on (step S105; No), the input function of the touch panel 34 is turned off (step S106). On the other hand, when it is determined that the input function of the touch panel 34 has already been turned off (step S105; Yes), the processing unit 24 advances the processing to step S107 while maintaining the off state.

  Next, the processing means 24 converts the coordinate information of the DOL coordinate system included in the received entry information into the coordinate information of the display coordinate system using the first coordinate conversion function stored in the storage means 25 (step S107). Then, the processing unit 24 performs an electronic pen input process (step S108). For example, based on the converted coordinate information, the processing unit 24 draws the stroke that has been entered on the image that is currently displayed by the display panel 35, and updates the display on the display panel 35. The image is updated and stored in the storage means 25. When the processing unit 24 determines that the input to the position designation area 51, the write designation area 52, or the display area 53 of the map application screen 50 has been made based on the coordinate information after conversion, Execute the process described in the [App screen] section.

  Next, the processing means 24 determines whether or not entry information has been received from the electronic pen 1 (step S109). If it is determined that the entry information has been received (step S109; Yes), the processing unit 24 continues the process of step S104 and performs the process based on the entry information. On the other hand, when it is determined that the entry information has not been received (step S109; No), the processing unit 24 turns the input function of the touch panel 34 back on (step S110). And the process means 24 complete | finishes the process of a flowchart.

  On the other hand, if it is determined in step S103 that the entry information has not been received (step S103; No), the processing unit 24 does not detect the touch panel input by a finger and does not involve an electronic pen input. Therefore, the input process is not performed and the process of the flowchart is terminated.

  If it is determined in step S102 that the contact area q satisfies the condition B (step S102; condition B), the processing unit 24 determines whether or not the indicated position can be specified based on the detected contact area (step S121). For example, the processing unit 24 obtains the center position of the detected contact area, determines whether or not the contact area falls within a circle area having a predetermined radius centered on the center position, and the contact area is within the circle area. If it fits, the contact area is specified as the designated position, and if the contact area does not fit within the circle area, it is determined that the designated position cannot be specified. If it is determined that the indicated position cannot be specified based on the detected contact area (step S121; No), the processing unit 24 ends the process of the flowchart. On the other hand, when the indicated position can be specified based on the detected contact area (step S121; Yes), the processing unit 24 converts the coordinate data of the touch panel coordinate system indicated by the touch panel input information received from the touch panel 34 to the second coordinate conversion function. Is converted into display coordinate system data (step S122), and touch panel input processing is performed (step S123). Specifically, when an icon such as a folder is displayed on the coordinate data after conversion in the image currently displayed on the display panel 35, the processing unit 24 performs processing such as selection of the icon. . When the processing unit 24 determines that the input to the position designation area 51, the write designation area 52, or the display area 53 of the map application screen 50 has been made based on the coordinate information after conversion, Execute the process described in the [App screen] section.

  On the other hand, when it is determined in step S102 that the contact area q does not satisfy both the conditions A and B (step S102; other than the conditions A and B), the processing unit 24 determines that the contact area is the hand side contact area or the like. In order to prevent erroneous input from the touch panel 34, the touch panel input process is not performed and the process of the flowchart is terminated.

[Operational effects of the input system of the first embodiment]
According to the input system of the first embodiment, the computer device 2 turns off the input function of the touch panel 34 while the contact area q satisfies the condition A and the entry information is received from the electronic pen 1. As a result, the computer device 2 detects the touch panel accompanying the touch panel input by the user's finger, the touch panel detection by the pen tip portion 103 accompanying the electronic pen input, and the side portion of the hand holding the electronic pen 1 contacts the DOL 30. It is possible to accurately discriminate the touch panel from the touch panel detection, accept only the touch panel input by the user's finger, and prevent erroneous input to the touch panel 34.

  In addition, the computer device 2 performs the touch panel input process when the contact area q satisfies the condition B and the touch panel input instruction position can be specified, and only when the detected contact area can be determined as the fingertip contact area. Since the processing is effectively performed as touch panel input, erroneous input to the touch panel 34 can be prevented. Further, even when the contact area q satisfies the condition B, the computer device 2 more reliably prevents erroneous input to the touch panel 34 by not executing the touch panel input process when the specified position cannot be specified. be able to.

  Note that the processing shown in FIG. 11 is executed for each contact area generated by touch panel input, and therefore touch input processing (step S123) is performed for any input when touch input is performed with a plurality of fingers. become. In addition, if an electronic pen input is performed while a touch panel input is performed with a finger and the touch panel input process is being performed, the touch panel function is turned off at step S106 and the electronic pen input process is performed preferentially. . Since the touch panel function is turned off while the electronic pen input process is being performed, the touch panel input process is not performed even if an attempt is made to perform a touch panel input with a finger in the middle. In addition, while drawing a stroke with a plurality of electronic pens, electronic pen input processing (step S108) is performed for each input while identifying entry information by the electronic pen ID.

  Further, the computer device 2 displays the map application screen 50 using the map application on the display device 3, generates latitude and longitude information of the position specified on the map in accordance with the position specifying operation, and performs the writing operation. Write information corresponding to the written memo is generated. Then, the computer apparatus 2 stores the latitude / longitude information and the writing information in association with each other. As a result, when the computer 2 again displays a map including the point where the position has been specified on the display area 53, the computer apparatus 2 displays the position specifying mark 55 and the handwritten memo written in association with the specified position. Can be displayed on a map.

  In addition, the computer device 2 includes a position designation area 51 and a write designation area 52 that perform the same processing on the map application screen 50 for electronic pen input and touch panel input, and a state in which the position designation area 51 is lit or the write designation area 52 A display area 53 is provided that performs different processing for electronic pen input and touch panel input in the lighted state. By doing in this way, the computer apparatus 2 can make a user use properly the electronic pen input and touch-panel input on the display area 53, can expand the range of operation, and can improve the convenience.

[Modification of First Embodiment]
Next, a modification of the first embodiment will be described. The following modifications may be applied in any combination to the first embodiment described above.

(Modification 1)
In FIG. 1 and FIG. 2, the DOL 30 and the touch panel 34 are stacked on the display panel 35. However, the configuration of the input system to which the present invention is applicable is not limited to this.

  FIG. 12 is a system configuration diagram of an input system according to Modification 1 of the first embodiment. As illustrated in FIG. 12, the input system according to the first modification of the first embodiment includes a projector 4 that projects the same image as the display screen of the display of the computer device 2 onto the DOL 30. Further, the DOL 30 and the touch panel 34 are stacked and disposed at a position away from the display of the computer apparatus 2. The touch panel 34 is connected to the computer device 2 and transmits touch panel input information to the computer device 2. Although the projector 4 shown in FIG. 12 is a front projector, it may be a rear projector. In addition, an imaging diffusion layer for imaging and diffusing the projected light may be adopted as a layer constituting the DOL 30 or the touch panel 34, or an imaging diffusion layer may be laminated separately from the DOL 30 and the touch panel 34.

  As described above, even when the DOL 30 and the touch panel 34 are not stacked on the display, the processing unit 24 of the computer apparatus 2 stores the coordinate information of the DOL coordinate system included in the entry information received from the electronic pen 1. Using the first coordinate conversion function stored by the means 25, it is converted into coordinate information of the display coordinate system, and electronic pen input processing is performed. Further, the processing means 24 converts the coordinate information of the touch panel coordinate system indicated by the touch panel input information received from the touch panel 34 into the coordinate information of the display coordinate system using the second coordinate conversion function stored by the entry means 25. The touch panel input process is performed. The processing unit 24 limits the input function of the touch panel 34 while the contact area q satisfies the condition A based on the flowchart shown in FIG. The touch panel input process is performed only when the contact area q satisfies the condition B and the indicated position can be specified.

Also with this configuration, the input system preferably accepts the electronic pen input and the touch panel input by the user's finger, and the touch panel resulting from the electronic pen 1 coming into contact with the DOL 30 during the input by the electronic pen 1. It is possible to prevent erroneous detection of input.
(Modification 2)
The input system shown in FIG. 1 has the map information providing server 4, but the configuration to which the present invention can be applied is not limited to this. Instead of this, the input system may not have the map information providing server 4. In this case, the computer device 2 is preinstalled with a map application including map information. Then, when there is a map movement operation or a map enlargement / reduction operation while the map application screen 50 is displayed, the computer device 2 updates the display of the display area 53 based on the installed map application.

(Modification 3)
In the first embodiment, the computer device 2 generates the latitude / longitude information of the position specified on the map and the writing information corresponding to the note written in relation to the specified position, generated according to the operation by the user. And stored in association with each other. In addition to this, the computer device may be configured to store a plurality of types of pattern position designation marks 55 so that the user can designate the type (picture) of the position designation mark 55 displayed at the designated position. Good. In this case, the computer apparatus 2 stores the latitude / longitude information, the mark identification information for specifying the type of the position designation mark 55, and the writing information in association with each other.

(Modification 4)
In the above-described embodiment, the computer device 2 displays a map in the display area 53 on the map application screen 50, and executes processing according to a position designation operation, a writing operation, and the like. However, the application to which the present invention is applicable is not limited to this. Instead of this, the computer apparatus 2 may accept a position designation operation and a writing operation even in various applications using design drawings, weather maps, virtual reality, photographs, illustrations, videos, and the like.

  This will be specifically described by taking as an example the case where the present invention is applied to an application using a design drawing such as a three-dimensional CAD (Computer Aided Design).

  First, the processing means 24 displays a design drawing on the display area 53 instead of a map. Then, the processing means 24 responds to the input stroke when there is a predetermined touch panel input or electronic pen input on the display area 53 when the position designation area 51 is off and the writing designation area 52 is off. The projection angle, size, position, etc. of the design drawing being displayed in the display area 53 are changed.

  On the other hand, when the position designation area 51 is lit and the processing means 24 detects an electronic pen input on the display area 53, the processing means 24 is designated from the design drawing expressed by a polygon or the like based on the entry information. The position is specified, a predetermined mark is attached to the position, and information on the position (position information) is stored. Further, when the writing designation area 52 is lit and the processing means 24 detects an electronic pen input on the display area 53, the processing means 24 displays a stroke corresponding to the electronic pen input on the display area 53. The stroke information (write information) is stored in the storage means 25 in association with the position information.

  On the other hand, when there is a touch panel input while the position designation area 51 is lit or the write designation area 52 is lit, the processing unit 24 performs operations other than the position designation operation and the write operation (for example, enlargement / reduction). It is determined that the operation has been performed, and the design drawing display is changed according to touch panel input. As described above, when the position designation area 51 or the write designation area 52 is lit, the processing unit 24 performs electronic pen input and touch panel input on the display area 53 as in the case of the map application screen 50. Perform different processing.

  As described above, the computer device 2 displays various display objects other than the map on the display area 53, and performs the same processing as the above-described processing according to the position specifying operation and the writing operation, thereby allowing the user to An arbitrary position in the display target can be designated and writing can be executed.

(Modification 5)
The touch panel function switching unit 243 determines whether or not the detected contact area is a pen tip contact area based on the condition A using the contact area q and the threshold values Q1 and Q2 and whether or not the entry information is received. However, the method to which the present invention is applicable is not limited to this. Instead of the condition A, the touch panel function switching unit 243 does not provide the threshold value Q1, and if the contact area q is smaller than the threshold value Q2 and receives entry information, the touch panel function switching unit 243 determines that the contact area is a pen tip contact area. Good. Even in this case, since it is determined whether or not entry information has been received in step S103, a contact that has not received entry information can be prevented from being handled as electronic pen input.

(Modification 6)
In the first embodiment, the Anoto coding pattern (dot pattern) is used. However, any coding pattern indicating position coordinates may be used, and the Anoto coding is not limited.

(Modification 7)
As described above, in the first embodiment, when an electronic pen input is performed while a touch panel input is performed with a finger and the touch panel input process is being performed, the touch panel function is turned off in step S106 at that time, and the electronic pen is operated. Since the input process is performed preferentially, it is advisable to display the fact on the display panel 35 for caution.

Second Embodiment
Next, a second embodiment will be described. FIG. 13 is a system configuration diagram of an input system according to the second embodiment. In the second embodiment, the processing unit 24 is different from the first embodiment in that the processing unit 24 includes a touch panel function limiting unit 244 that limits the period and range of invalidating the touch panel input instead of the touch panel function switching unit 243. In addition, about the part similar to 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted suitably. Further, when the processing unit 24 determines that an input to the position designation area 51, the write designation area 52, or the display area 53 of the map application screen 50 is made based on the converted coordinate information, the first embodiment Execute the process described in the [Map App Screen] section.

  The touch panel function restriction unit 244 of the processing unit 24 is within a predetermined range from the pen tip position (also referred to as “electronic pen input position”) of the electronic pen 1 while the computer apparatus 2 receives the entry information from the electronic pen 1. The input function of the touch panel 34 is turned off. Then, when the electronic pen input position changes, the processing unit 24 determines a range in which the input function of the touch panel 34 is turned off based on the changed electronic pen input position. Hereinafter, a range in which the input function of the touch panel 34 is turned off based on the electronic pen input position is also referred to as a “restricted range Wr”.

  Specific processing of the touch panel function restriction unit 244 will be further described with reference to FIG. FIG. 14 is an example of a display screen of the display device 3 in the second embodiment.

  In FIG. 14, the user touches the pen tip portion 103 of the electronic pen 1 on the DOL 30. In this case, the processing unit 24 converts the coordinate data included in the entry information received from the electronic pen 1 into coordinate data in the display coordinate system using the first coordinate conversion function, and the position of the coordinate data is converted to the electronic pen. Determine the input position. Then, the processing unit 24 determines a circular area having a radius R centered on the electronic pen input position as the limit range Wr, turns off the input function of the touch panel 34 in the limit range Wr, and sets the area outside the limit range Wr. The input function of the touch panel 34 is turned on. The radius R described above is set to, for example, 10 cm to 15 cm. Specifically, when an input with the electronic pen 1 is performed on the DOL 30, the side portion of the hand that holds the electronic pen 1 from the electronic pen input position is determined. The maximum distance to a position where there is a possibility of contact on the DOL 30 is determined in advance based on experiments or the like.

  Further, when the electronic pen input position changes, the processing unit 24 newly sets a limit range Wr based on the changed electronic pen input position, and turns off the input function of the touch panel 34 in the range. Therefore, while the stroke is drawn by the electronic pen 1, the limit range Wr also moves with the movement of the electronic pen input position. Further, when receiving the entry information from the plurality of electronic pens 1, the processing unit 24 provides a limit range Wr corresponding to each electronic pen 1. Specifically, in this case, the processing unit 24 specifies each electronic pen input position based on the entry information of each electronic pen 1 and determines the limit range Wr based on the electronic pen input position. In this case, the limited range Wr is an area on the DOL 30 that is a combination of circular areas with a radius R centered on each electronic pen input position.

[Processing flow]
Next, a processing flow based on touch panel input detection in the input system of the second embodiment will be described. The processing flow shown in FIG. 15 is repeatedly executed each time the computer apparatus 2 receives touch panel input information from the touch panel 34. In the processing flow shown in FIG. 15, when touch panel input information corresponding to a plurality of contact areas is received at the same time, the processes after step S <b> 202 are executed in parallel for each contact area.

  When the touch panel 34 detects contact on the DOL 30, the touch panel input information is transmitted to the computer apparatus 2. Thereby, the processing means 24 of the computer apparatus 2 detects that there was a touch panel input (step S201). Next, the processing means 24 calculates the contact area q of each contact region based on the coordinate data of the touch panel coordinate system indicated by the touch panel input information received from the touch panel 34, and each contact area q is determined based on the condition A (Q1 < It is determined whether q <Q2) is satisfied, condition B (Q3 <q <Q4) is satisfied, or neither of conditions A and B is satisfied (step S202).

  When it is determined that the condition A is satisfied (step S202: condition A), the processing unit 24 determines whether new entry information is received from the electronic pen 1 (step S203). Thereby, the processing means 24 determines whether or not the detection of the touch panel input in step S101 is based on the contact on the DOL 30 of the new electronic pen 1 during the electronic pen input. Note that when the electronic pen 1 is downed, the touch panel input detection timing is earlier than the timing at which the computer apparatus 2 receives the entry information due to the time for the electronic pen 1 to generate the entry information. . Accordingly, the processing unit 24 determines whether or not entry information is received from the new electronic pen 1 for a predetermined time width corresponding to the above-described timing difference (time lag) after the execution of step S201.

  When it is determined that new entry information is received (step S203; Yes), the processing unit 24 causes the storage unit 25 to store the entry information for each pen ID (step S204). Next, the processing means 24 converts the coordinate information of the DOL coordinate system included in the received entry information into the coordinate information of the display coordinate system using the first coordinate conversion function stored in the storage means 25 (step S205). Then, the processing unit 24 specifies the electronic pen input position based on the converted coordinate information, and turns off the input function of the touch panel 34 within a predetermined range from the electronic pen input position (step S206). Specifically, the processing means 24 turns off the input function of the touch panel 34 in a circular area with a radius R centered on the electronic pen input position. Then, the processing unit 24 performs an electronic pen input process (step S207).

  Next, the processing means 24 determines whether or not entry information is continuously received from the same electronic pen 1 as the electronic pen 1 subjected to the electronic pen input process in step S207 (step S208). If it is determined that entry information has been received from the same electronic pen 1 (step S208; Yes), the processing unit 24 proceeds to the process of step S204 and performs processing based on the entry information.

  On the other hand, when it is determined that entry information has not been received from the same electronic pen 1 (step S208; No), the processing means 24 is the electronic pen of the electronic pen 1 that has been the target of a series of electronic pen input processes. The restriction on the input function of the touch panel 34 based on the input position is released (step S209). And the process means 24 complete | finishes the process of a flowchart. When there is another electronic pen 1 that has received the entry information, the processing unit 24 continues to use the touch panel 34 in a circular area having a radius R from the electronic pen input position of the other electronic pen 1. Turn off the input function.

  On the other hand, when it is determined in step S203 that entry information has not been received from the new electronic pen 1 (step S203; No), the processing unit 24 ends the process of the flowchart. Note that the entry information continuously received from the same electronic pen 1 from the touch panel input detection before the processing has been subjected to the electronic pen input processing by the steps S204 to S208 loop processing before the processing. Then, the electronic pen input process is not performed.

  When it is determined in step S202 that the contact area q satisfies the condition B (step S202; condition B), the processing unit 24 determines whether or not the indicated position can be specified based on the detected contact area (step S221). If it is determined that the indicated position cannot be specified based on the detected contact area (step S221; No), the processing unit 24 ends the process of the flowchart. On the other hand, when the designated position can be specified based on the detected contact area (step S221; Yes), the processing unit 24 converts the coordinate data of the touch panel coordinate system indicated by the touch panel input information received from the touch panel 34 to the second coordinate conversion function. Is converted into display coordinate system data (step S222), and it is determined whether or not the converted coordinate information is within the limit range Wr (step S223). And when it determines with the coordinate information after conversion being outside the restriction | limiting range Wr (step S223; No), the process means 24 performs a touchscreen input process (step S224). On the other hand, when it determines with the coordinate information after conversion being in the restriction | limiting range Wr (step S223; Yes), the process means 24 does not perform a touchscreen input process, but complete | finishes the process of a flowchart.

  On the other hand, when it is determined in step S202 that the contact area q does not satisfy both the conditions A and B (step S202; other than the conditions A and B), the processing unit 24 determines that the contact area is a hand side contact area or the like. In order to prevent erroneous input from the touch panel 34, the touch panel input process is not performed and the process of the flowchart is terminated.

[Concrete example]
Next, a specific example of the processing shown in the flowchart of FIG. 15 will be described in more detail with reference to FIG. FIG. 16 is a schematic diagram when a plurality of users (Mr. A, Mr. B, Mr. C, and Ms. D) perform input on the display device 3 in the second embodiment. In the following, it is assumed that Mr. A uses the electronic pen 1A with the pen ID “pen01”, Mr. B uses the electronic pen 1B with the pen ID “pen02”, and inputs sequentially from Mr. A. It is assumed that the limit range Wr is not provided.

  First, Mr. A holds the electronic pen 1 </ b> A and performs pen-down on the DOL 30 to perform writing. Thereby, the computer apparatus 2 detects a touch panel input by the touch panel 34 (see step S201), and determines that the contact area q corresponding to the detected contact area satisfies the condition A (see step S202). Furthermore, since the entry information is transmitted from the electronic pen 1A to the computer device 2, the computer device 2 determines that the entry information has been received from the new electronic pen 1 (see step S203), and is included in the received entry information. The coordinate information of the DOL coordinate system is converted into the coordinate information of the display coordinate system using the first coordinate conversion function (see step S205), and the electronic pen input position of the electronic pen 1A is specified based on the coordinate information after the conversion Then, the range of the radius R from the electronic pen input position is determined as the limit range Wr as the limit range Wra (see step S206). And the computer apparatus 2 performs the electronic pen input process of the electronic pen 1A (refer step S207). When the electronic pen input position changes, the computer apparatus 2 updates the limit range Wr based on the changed electronic pen input position.

  Even if the hand side portion contact area is detected together with the pen tip contact area as a result of Mr. A pen-downing the electronic pen 1A onto the DOL 30, the computer apparatus 2 has the contact area q as the condition A and the condition A. Since B is not satisfied (see step S202), the input process corresponding to the hand side portion contact area is not performed.

  Next, Mr. B holds the electronic pen 1B and performs writing on the DOL 30 by pen-downing at a position separated from the electronic pen input position of the electronic pen 1A by a distance R or more. Thereby, the computer apparatus 2 detects a touch panel input by the touch panel 34 (see step S201), and determines that the contact area q corresponding to the pen tip contact area satisfies the condition A (see step S202). At this time, since the entry information is transmitted from the electronic pen 1B to the computer device 2, the computer device 2 determines that the entry information has been received from the new electronic pen 1 (see step S203), and the received entry information is included in the received entry information. Based on this, the electronic pen input position of the electronic pen 1B is specified, and the range of radius R from the electronic pen input position is added to the limited range Wr as the limited range Wrb (see step S206). And the computer apparatus 2 performs the electronic pen input process of the electronic pen 1B (refer step S207).

  Next, Mr. C brings his finger into contact with a position other than the limit range Wr on the DOL 30. Thereby, the computer apparatus 2 detects a touch panel input by the touch panel 34 (see step S201), and determines that the contact area q corresponding to the fingertip contact area satisfies the condition B (see step S202). Further, the computer device 2 determines that the indicated position can be specified from the detected contact area (see step S221), and uses the second coordinate conversion function to obtain the coordinate information of the touch panel coordinate system indicated by the received touch panel input information, Conversion into coordinate information of the display coordinate system is performed (see step S222). Furthermore, since the coordinate information is outside the limit range Wr (see step S223), the computer apparatus 2 performs touch panel input processing based on the coordinate information (see step S224).

  Furthermore, Mr. D brings his finger into contact with the position on the DOL 30 and within the limited range Wra (Wr). Thereby, the computer apparatus 2 detects a touch panel input by the touch panel 34 (see step S201), and determines that the contact area q corresponding to the fingertip contact area satisfies the condition B (see step S202). Furthermore, since the contact area is substantially circular and the indicated position can be specified, the computer apparatus 2 uses the second coordinate conversion function to display the coordinate information of the touch panel coordinate system indicated by the received touch panel input information as display coordinates. Conversion into system coordinate information is performed (see step S222). However, in this case, since the converted coordinate information is within the limited range Wra (Wr) (see step S223), the computer apparatus 2 does not perform touch panel input processing.

[Operational effects of the input system of the second embodiment]
According to the input system of the first embodiment, the computer device 2 turns off the input function in the predetermined range of the touch panel 34 while the contact area q satisfies the condition A and the entry information is received from the electronic pen 1. To. As a result, the computer device 2 detects the touch panel accompanying the touch panel input by the user's finger, the touch panel detection by the pen tip portion 103 accompanying the electronic pen input, and the side portion of the hand holding the electronic pen 1 contacts the DOL 30. It is possible to accurately discriminate the touch panel from the touch panel detection, accept only the touch panel input by the user's finger, and prevent erroneous input to the touch panel 34.

  Further, the computer device 2 turns off the input function of the touch panel 34 only within a predetermined range based on the electronic pen input position, thereby causing an error caused by the electronic pen 1 abutting on the DOL 30 during the electronic pen input. It is possible to effectively process an intended touch panel input by a finger of one hand or a finger of another user while preventing the input. Therefore, 2nd Embodiment is applied suitably also when the display apparatus 3 has a large sized screen and a touch panel input is performed by several people.

  In addition, the computer device 2 performs the touch panel input process when the contact area q satisfies the condition B and the touch panel input instruction position can be specified, and only when the detected contact area can be determined as the fingertip contact area. Since the processing is effectively performed as touch panel input, erroneous input to the touch panel 34 can be prevented. Further, even when the contact area q satisfies the condition B, the computer device 2 more reliably prevents erroneous input to the touch panel 34 by not executing the touch panel input process when the specified position cannot be specified. be able to.

At this time, it is preferable that the area opposite to the dominant hand of the user who uses the electronic pen 1 is not limited. The user's dominant hand may be stored in the storage unit 25 in association with the pen ID of the electronic pen 1 used in advance, or the electronic pen 1 is provided with an angle sensor or the distortion pattern of the dot pattern photographed by the electronic pen 1 The inclination of the electronic pen 1 may be obtained from the information, and the inclination information may be included in the entry information.
