Description

  The present invention provides an information terminal device including a touch display panel for displaying an image on a display surface and detecting contact of a detection target with the display surface, and an image display method and image display in such an information terminal device. Regarding the program.

  In recent years, various information terminal devices equipped with a touch display panel have become widespread. A user who uses such an information terminal device operates the operation mark displayed on the touch display panel as an operation button, and causes the information terminal device to realize various functions. In US Patent Application Publication No. US2007 / 0273663 (Patent Document 1), a user's finger or a stylus pen is used to make a user's request via an operation mark (memu 50) displayed on a touch display panel. An operation method for causing an information terminal device to execute the above function is disclosed. In Patent Document 1, a plurality of operation marks (memu 50) each assigned a specific function are arranged in a selection area (a selection area 30a), and one of the operation marks is designated as an execution area (an execution area). By moving to 30b), the function assigned to the operation mark is executed. As one aspect, the user touches a desired operation mark with a fingertip or a stylus pen, and moves the operation mark from the selection area to the execution area while keeping the contact. That is, a function assigned to a desired operation mark is executed by performing a so-called “drag” operation (Patent Document 1: [0041]-[0051], Figs. 5-6D, etc.).

  Since such a drag operation is easy to operate, it is a mode suitable for a case where one of a plurality of operation marks is selected and executed. However, if the operation mark to be operated is about the size of a typical human fingertip, for example, the operation mark may be hidden and the user may get lost during the operation. If the operation mark is enlarged in order to ensure visibility, the number of selectable operation marks is reduced, which may reduce convenience. Further, in a simple drag operation, the detailed state of the change accompanying the movement of the operation mark cannot be expressed, and there is a possibility that a difference occurs between the operation of the information terminal device and the operation result expected by the user.

US Patent Application Publication No. US2007 / 0273663

  In view of the above background, a graphic user interface that is easily adapted to the user's sensibility and that allows the user to easily recall the results associated with the operation on the touch display panel is desired.

In view of the above problems, the characteristic configuration of the information terminal device according to the present invention is as follows:
An information terminal device comprising a touch display panel for displaying an image on a display surface and detecting contact of a detection target with the display surface,
A display control unit for displaying a display image including a plurality of operation marks on the touch display panel;
A coordinate specifying unit that specifies the contact position of the detection target with respect to the touch display panel as indicated coordinates in the display image,
The display control unit
In the display image, a determination area for determining that one operation mark has been selected and a non-determination area set without overlapping the determination area are displayed separately,
In a non-operation state in which contact of the detection target with the operation mark is not detected, each of the operation marks is displayed in a standard display state at a predetermined initial display position in the non-determined area. ,
In the operation state in which the contact of the detection target is detected with respect to the selected mark which is one of the operation marks, the other operation displayed in the standard display state is displayed on the selected mark. A mark that is displayed in the initial display position in a low-tone display state in which visibility is reduced compared to the mark, and that is expressed in a form that maintains the design of the selected mark, depending on the contact position. Display a movable mark that can be moved at the contact position,
In the operation state, when the contact position belongs to the non-determined region, the movable mark and the selected mark are displayed,
In the operation state, when the contact position belongs to the determination area, the movable mark is displayed and the selected mark is not displayed.

  According to this characteristic configuration, when the contact position belongs to the non-determined area in the operation state in which the contact of the detection target is detected with respect to the selected mark, the selected mark is displayed in a weak tone and is movable. The mark is displayed at the contact position. On the other hand, when the contact position belongs to the determination area in the operation state, only the movable mark is displayed without displaying the selected mark. That is, it is possible to sensuously inform the user that the result of the subsequent operation differs depending on whether the movable mark exists in the non-determined area or the determined area. For example, the user can be reminded by the display content whether or not the function assigned to the operation mark corresponding to the selected mark or the movable mark is executed. As described above, according to the present feature configuration, it is possible to provide a graphic user interface (GUI) that is easily adapted to the user's sensibility and that allows the user to easily recall the result of the operation on the touch display panel.

  Here, in the information terminal device according to the present invention, the display control unit displays the movable mark in a highlighted state in which the visibility is improved compared to the other operation marks displayed in the standard display state. It is preferable to display it. By highlighting the movable mark, even if a finger, a stylus pen, or the like and the operation mark (in this case, the movable mark) overlap, a decrease in the visibility of the movable mark is suppressed. Furthermore, by highlighting the movable mark, the user can grasp well that the function assigned to the operation mark (selected mark) of the same design as the movable mark can be executed. be able to. In addition, since the difference from the selected mark that is displayed in weak tone at the initial display position becomes clearer, the user can surely grasp the operation mark that is being operated to execute the function.

  Further, in the information terminal device according to the present invention, when the display control unit further displays a direction indication mark that instructs a direction from the movable mark toward the determination area according to a position of the movable mark. Is preferred. As described above, the display control unit performs display so that the user can easily recall the result of the operation on the touch display panel. Furthermore, when the function assigned to the movable mark is executed, the direction indicating mark indicating the direction in which the movable mark is moved is displayed, so that the user can perform a more reliable operation.

  As described above, in the information terminal device according to the present invention, the display form is different depending on whether the movable mark belongs to the non-determined area or the case where the movable mark belongs to the determined area. Can be conveyed to the user sensuously. For example, when the movable mark belongs to the non-determined area and the case where the movable mark belongs to the determined area, the detection target and the touch display panel have different execution forms after changing from the contact state to the non-contact state. The execution result can be recalled to the user. As one aspect, the display control unit of the information terminal device according to the present invention is configured such that the contact between the detection target and the touch display panel is released in a state where the movable mark belongs to the determination area. The function assigned to the operation mark corresponding to the movable mark is executed, and the contact between the detection object and the touch display panel is released in a state where the movable mark belongs to the non-determined area. Preferably, the movable mark is not displayed and the operation mark corresponding to the selected mark is displayed in the standard display state at the initial display position. Thus, when the selected mark is displayed at the initial display position, the function corresponding to the selected mark is not executable, and when the selected mark is not displayed, it corresponds to the selected mark. If the function is executable, the result of the subsequent operation is easily recalled by the user.

  Here, it is preferable that the non-decision area is set around the decision area, and the initial display position of the operation mark is set around the decision area. If an operation mark is arranged around the decision area, the detection target has almost the same amount of movement regardless of the operation mark that is operated toward the decision area, so that high operability is obtained. be able to.

  Further, it is preferable that the determination area is set in a circular shape, and the initial display position is arranged along a circumference. When the positional relationship between the determination area and the initial display position is in such a form, the uniformity of the distance between each operation mark and the determination area becomes high, and higher operability can be obtained.

  Various technical features of the above-described information terminal device according to the present invention include an image display method for displaying a display image including a plurality of operation marks on the touch display panel in an information terminal device including a touch display panel, It can also be applied to an image display program. Therefore, the present invention can also cover such an image display method and an image display program. For example, the image display method and the image display program according to the present invention can also provide the above-described effects of the information terminal device. Further, various additional features exemplified as preferred aspects of the information terminal device can be incorporated into the image display method and the image display program, and the image display method and the image display program correspond to the respective additional features. An effect can also be produced.

In that case, the characteristic configuration of the image display method is as follows:
In an information terminal device including a touch display panel for displaying an image on a display surface and detecting contact of a detection target with the display surface, a display image including a plurality of operation marks is displayed on the touch display panel. An image display method,
A coordinate specifying step of specifying a contact position of the detection object with respect to the touch display panel as an indicated coordinate in the display image;

In the operation state in which the contact of the detection target is detected with respect to the selected mark that is one of the operation marks, the other operation displayed in the standard display state with the selected mark being displayed. A mark that is displayed in the initial display position in a low-tone display state in which visibility is reduced compared to the mark, and that is expressed in a form that maintains the design of the selected mark, depending on the contact position. A display step at the time of selection to display a movable mark movable at the contact position;
In the operation state, when the contact position belongs to the non-determined area, the non-determinable display step for displaying the movable mark and the selected mark;
In the operation state, when the contact position belongs to the determination region, a determination possible time display step that displays the movable mark and hides the selected mark;
It is in the point provided with.

In this case, the characteristic configuration of the image display program is as follows:

  Hereinafter, the embodiment of the present invention will be described based on the drawings using an example in which the smartphone 1 is applied as an information terminal device. Here, the smartphone means a multi-function mobile phone having high affinity with the Internet and made based on the function of a personal computer. The information terminal device can be applied to a portable music player with a data communication function, a portable information terminal such as a camera with a data communication function, a personal computer, an in-vehicle navigation system, or the like. Needless to say, the portable information terminal is not limited to a small portable device that fits in the palm of the hand, and includes a tablet terminal having a screen size of 7 to 9 inches or more.

  FIG. 1 shows the appearance of the smartphone 1. The smartphone 1 includes a touch display panel 2 that displays an image on a display surface and detects contact of a detection target with the display surface. The smartphone 1 is configured to be able to execute various application programs. FIG. 1 shows an example in which a portal screen of a portal application program (post) for selecting these various application programs is displayed. On this portal screen, operation icons F (operation marks) that can start various application programs in response to user operation instructions are arranged. FIG. 1 illustrates a form in which the portal screen including the operation icon F is displayed in the standard display state.

  The portal screen includes a determination area R1 for determining that one operation icon F has been selected in the display image of the touch display panel 2, and a non-determination area R2 set without overlapping the determination area R1. Are displayed separately. The non-decision area R2 is set around the decision area R1, and the initial display position of the operation icon F (operation mark) is set around the decision area R1. In the present embodiment, the determination region R1 is set in a circular shape, and the initial display position is set in an annular arrangement region R3 set along the circumference. As will be described later, when the operation icon F is operated toward the determination area R1, the application assigned to the operation icon F is executed. In order to clearly indicate this operation, an operation explanation mark A indicating a direction from the operation icon F toward the determination region R1 is also displayed.

  In the present embodiment, operation icons F (F1 to F5) assigned to five application programs are displayed on the portal screen. In this embodiment, each application program is an icon design setting application program (F1: CHARACTER), a map decoration application program (F2: MAP), an application program (F3: Billbordard) that distributes news, etc., and a wallpaper setting application. A program (F4: paper) and a route guidance application program (Route). The operation icons F (F1 to F5) to which these five application programs are assigned are arranged in the arrangement area R3 as described above.

  As shown in FIG. 1, the determination region R1 is set in a circular shape, and the arrangement region R3 is set in an annular shape with concentric circles along the outer periphery of the determination region R1. A further outer peripheral side of the arrangement area R3 is a background area R4, and the non-determining area R2 is configured to include an arrangement area R3 and a background area R4. As will be described later, the smartphone 1 incorporates a sensor that detects the posture of the smartphone 1 and changes (adjusts) the display image displayed on the touch display panel 2 according to the posture. For example, as shown in FIG. 2, the display image can be horizontally long or vertically long depending on the posture of the smartphone 1. Since both the determination area R1 and the arrangement area R3 are arcuate, the same layout can be maintained regardless of the posture of the smartphone 1. In other words, the adjustment according to the posture of the smartphone 1 is supported in the background region R4.

  Here, an example of an operation by the user and a change in the display form of the display screen until the operation program selected by the user is selected and the application program assigned to the operation icon F is executed will be described. When the detection target T such as a user's finger or stylus pen contacts one of the plurality of operation icons F, the one operation icon F is selected and becomes the selection icon S. In this example, the operation icon “F1” is selected.

  In the present embodiment, the state in which the contact of the detection target T with the selection icon S (selected mark) that is one of the operation icons F is detected is referred to as an “operation state”. When the contact position of the detection target T belongs to the non-determined region R2 in this “operation state”, the operation icon “F1” is visually recognized compared to the other operation icons “F2 to F5” displayed in the standard display state. Displayed at the initial display position in a “weak tone display state” with reduced performance. Along with this, a movable icon M (movable mark) that is a mark that is expressed in a form that maintains the design of the selection icon S (operation icon “F1”) and that can be moved according to the contact position of the detection target T. ) Is displayed at the contact position.

  Here, the “weak tone display state” means that the operation icon “F1” corresponding to the selected icon S is changed in brightness, saturation, hue, or more than the other operation icons “F2 to F5”. The display form is adjusted so as not to stand out. Further, the size of the mark may be changed instead of such adjustment of color and shade, or together with adjustment of color and shade. That is, the size of the operation icon “F1” corresponding to the selection icon S may be made less conspicuous by making it smaller than the other operation icons “F2 to F5”. The form illustrated in FIG. 3 shows an example in which the size is maintained and the brightness or saturation is reduced.

  In the operation state, it is preferable that the movable icon M is further displayed in the “highlighted display state” with higher visibility than the other operation icons “F2 to F5” displayed in the standard display state. The “highlighted display state” refers to a state that is more conspicuous than the other operation icons “F2 to F5” by adjusting the color tone and the size, contrary to the “weak display state”. In the present embodiment, an example in which the size is increased while the design of the operation icon “F1” is maintained is shown. By highlighting the movable icon M, even if the detection target T such as a finger or a stylus pen overlaps with the operation icon F (in this case, the movable icon M), a decrease in the visibility of the movable icon M is suppressed. Is done. Furthermore, the user can better understand that the function assigned to the operation icon F (selected icon S) having the same design as the movable icon M can be executed by highlighting the movable icon M. Can do. In addition, since the difference from the selection icon S that is displayed in weak gradation at the initial display position becomes clearer, the user can surely grasp the operation icon F that is being operated to execute the function. Naturally, the movable icon M is not necessarily displayed in a highlighted state, and does not hinder the form in which the movable icon M is displayed with exactly the same design as the original operation icon F.

  By the way, in this embodiment, as shown in FIG. 3, a direction indication mark Y that indicates a direction from the movable icon M toward the determination region R <b> 1 is further displayed according to the position of the movable icon M. Similar to the movable icon M whose display position moves according to the contact position, the direction indicating mark Y is also a dynamic mark whose display position and direction change according to the position of the movable icon M. When the movable icon M is moved to the determination region R1, the direction indication mark Y indicating the direction in which the movable icon M is moved is displayed, so that the user can perform a more reliable operation. This direction indicating mark Y is a display form that is more emphasized than the operation explanation mark A indicating the direction from the operation icon F toward the determination region R1 as described above. Depending on the display form of the selection icon S and the movable icon M, a display that makes it easy for the user to recall the result of the operation on the touch display panel is performed. However, by displaying the direction indication mark Y, the user can More reliable operation is possible. At this time, similarly to the operation icon F corresponding to the selection icon S, the operation explanation mark A corresponding to the selection icon S may be displayed in a lower tone than the other operation explanation marks A. Needless to say, the direction indication mark Y does not necessarily need to be additionally displayed, and does not hinder the form in which the direction indication mark Y is not additionally displayed.

  Note that when the contact between the detection target T and the touch display panel 2 is released in a state where the movable icon M is not located in the determination region R1, the movable icon M and the direction indication mark Y are not displayed. Then, the operation icon “F1” corresponding to the selection icon S is displayed again in the standard display state at the initial display position. At this time, as shown in FIG. 4, the movable icon M enlarged and displayed at the position where the detection target T and the touch display panel 2 are in contact with each other moves to the initial display position while being reduced, and the initial display is performed. When the display form of the selection icon S returns to the standard display state when the position is reached, it is preferable that dynamic movement is expressed. That is, it is dynamically expressed that the standby state of the initial screen is changed from the executable state. When the operation explanation mark A is displayed in a weak tone, the operation explanation mark A also returns to the standard display state. A weakly displayed selection icon S is displayed at the initial arrangement position, and the display form of the selection icon S changes to the standard display state, so that the user can clearly understand the change of the screen. .

  As described above, when the contact position belongs to the non-determined region R2 in the “operation state”, the selection icon S and the movable icon M are displayed. On the other hand, when the contact position belongs to the determination region R1 in the “operation state”, the movable icon M is displayed while the selection icon S and the direction indication mark Y are not displayed as shown in FIG. Since the selection icon S is hidden, it is indicated that there is no place where the movable icon M returns even when the contact between the detection target T and the touch display panel 2 is released. Further, the non-display of the direction indicating mark Y indicates that it is not necessary to move the movable icon M in order to execute the function assigned to the movable icon M (operation icon F). That is, it is explicitly indicated that the current state is a state in which the function assigned to the movable icon M (operation icon F) is executed. At this time, similarly to the operation icon F corresponding to the selection icon S, the operation explanation mark A corresponding to the selection icon S is preferably not displayed.

  When the contact between the detection target T and the touch display panel 2 is released in a state where the movable icon M belongs to the determination region R1, the function assigned to the operation icon “F1” corresponding to the movable icon M is executed. The In the present embodiment, as shown in FIG. 6, the icon design setting application program (F1: CHARACTER) is activated, and a transition is made to a screen for selecting an icon design candidate FC. An operation icon “FB” for returning to the portal screen of the portal application program (post) is displayed at the upper left of the screen.

  Such display image control is executed with the display control unit 3 built inside the smartphone 1 as a core. Hereinafter, the functional configuration of the smartphone 1 for performing such screen display will be described. FIG. 7 is a block diagram schematically illustrating the hardware configuration of the smartphone 1. Most of the hardware of the smartphone 1 is mounted on a board called a main board 10 (mother board). Main peripheral devices such as the antenna 16, the camera 13, and the microphone 15m are also connected to the main board 10.

  The main board 10 is equipped with a main processor MP as a core of the smartphone 1, a flash memory 10f storing a program (software) executed in the main processor MP, and a main memory 10m storing a temporary file during program execution. ing. The main memory 10m may be a volatile memory, for example, a DRAM. In the present embodiment, the memory card 15 c is also detachable from the smartphone 1. The main processor MP can also use various data including images and sounds, application programs, and the like stored in the memory card 15c. The display control unit 3 and the coordinate specifying unit 5 to be described later are functional units realized by cooperation of hardware such as the main processor MP and the memory (10f, 10m) and a program (software). Various programs may be stored in an independent storage medium such as the flash memory 10f and the memory card 15c, or may be stored in a storage area (storage medium) built in the main processor MP.

  The smartphone 1 is equipped with a wireless communication module 10t that supports a plurality of methods. In the present embodiment, as the wireless communication module 19, a baseband processor 19b that controls communication with a mobile phone network and a wireless LAN module 19r that controls communication via a wireless LAN are mounted on the main board 10. Illustrated. A baseband antenna 16b connected to the baseband processor 19b and a wireless LAN antenna 16r connected to the wireless LAN module 19r are also connected to the main board 10. The smartphone 1 is also provided with a microphone 15m and a speaker 15s that are used during a call. The main board 10 is equipped with a voice module 10v and an audio module 10a. The microphone 15m is connected to the main processor MP via the voice module 10v. The speaker 15s is connected to the main processor MP via the audio module 10a and the voice module 10v.

  The touch display panel 2 includes a display panel 2d that functions as a display unit and a touch panel 2t that functions as a detection unit. In the present embodiment, the display panel 2d and the touch panel 2t are integrated to form the touch display panel 2. The smartphone 1 is equipped with a camera 13. The captured image captured by the camera 13 is directly transmitted through the main processor MP, or directly through a data bus provided on the main board 10 by DMA transfer or the like, to the main memory 10m, the memory card 15c, the flash memory 10f, etc. Stored in

  In addition, the smartphone 1 is equipped with various sensors such as a gyro sensor, an acceleration sensor, an atmospheric pressure sensor, a temperature sensor, a direction sensor, and a gravity sensor. In this embodiment, the form by which the acceleration sensor 10s (attitude | position detection part) is mounted in the main board 10 is illustrated. The acceleration sensor 10s detects the tilt and orientation of the smartphone 1. That is, the acceleration sensor 10s detects the vertical direction of the smartphone 1, and the main processor MP can control the display direction on the touch display panel 2 according to the vertical direction (see FIG. 2). In the present embodiment, an example in which the acceleration sensor 10s is used is illustrated, but a gravity sensor or a gyro sensor may be used. Of course, a plurality of sensors may be mounted.

  The main processor MP includes at least two functional units, a display control unit 3 and a coordinate specifying unit 5. The display control unit 3 is a functional unit that displays a display image including a plurality of operation icons F on the touch display panel 2. The coordinate specifying unit 5 is a functional unit that specifies the contact position of the detection target T with respect to the touch display panel 2 as designated coordinates in the display image. In FIG. 7, for convenience, the main processor MP is shown with the display control unit 3 and the coordinate specifying unit 5. As described above, these functional units include hardware, programs, and the like. The main processor MP does not have to be provided in all.

  FIG. 8 shows an example of coordinates such as designated coordinates P managed by the coordinate specifying unit 5 and initial display coordinates D (initial display position). “Q” is the center coordinates of the determination region R1 set in a circular shape. In the present embodiment, initial display coordinates D (D1 to D5) of the operation icons F (F1 to F5) are set on the circumference centered on the center coordinate Q. And the coordinate specific | specification part 5 specifies the contact position of the detection target T with respect to the touch display panel 2 as the instruction | indication coordinate P in a display image. The movable icon M is displayed using the designated coordinates P as a drawing reference position. A straight line “L” connecting the designated coordinate P and the central coordinate Q indicates a direction from the designated coordinate P toward the central coordinate Q. Accordingly, the direction indicating mark Y is drawn along the straight line “L”. The direction indication mark Y is dynamically determined by determining the posture and display coordinates according to the distance between the coordinates calculated based on the indication coordinates P and the center coordinates Q and the angle with respect to the reference coordinates of the display image. Is displayed.

  Hereinafter, an example of a processing procedure of an image display method (image display program) for displaying a display image including a plurality of operation icons F on the touch display panel 2 will be described using the flowchart of FIG. Here, the control (display control step / function) by the display control unit 3 will be mainly described. However, along with the control by the display control unit 3, the coordinate specifying unit 5 determines the contact position of the detection target T with respect to the touch display panel 2. Naturally, a process (coordinate specifying step / function) for specifying the designated coordinates P in the display image is also performed.

  When the portal application program (post) in which operation icons F (operation marks) capable of executing various functions are arranged is executed by the main processor MP, the portal screen is displayed as a display image by the display control unit 3. (# 10: initial screen display step / function). At this time, the display control unit 3 classifies the determination region R1 that determines that one operation icon F has been selected in the display image and the non-determination region R2 that is set without overlapping the determination region R1. To display (area setting step / function). In addition, the display control unit 3 displays each of the operation icons F in the non-determining region R2 with each of the initial display coordinates D defined in advance in a non-operation state in which the contact of the detection target T with the operation icon F is not detected. Display in standard display state at (initial display position) (standard display step / function). In the present embodiment, the operation icons F are arranged and displayed. That is, the initial screen display step / function (# 10) includes an area setting step / function and a standard display step / function.

  Whether the contact state of the detection target T is detected with respect to the selection icon S that is one of the operation icons F in the state in which the initial screen display step / function (# 10) is being executed. It is determined whether or not (# 20). If it is not in the operation state (if there is no contact), the execution of the initial screen display step / function (# 10) is continued. If it is an operation state (if there is contact), the display control unit 3 is a weak display state in which the selection icon S is less visible than the other operation icons F displayed in the standard display state. A mark that is displayed in the initial display coordinates D and is expressed in a form in which the design of the selection icon S is maintained, and a movable icon M that can be moved according to the contact position (indicated coordinates P) is displayed in the contact position (indicated coordinates P). (# 30: Display step / function when selected). The selection display step / function (# 30) includes a non-decidable display step / function (# 30A) and a decidable display step / function (# 30B), as will be described later. In the operation state, when the contact position (indicated coordinate P) belongs to the non-decision region R2, the display control unit 3 displays the movable icon M and the selection icon S (# 30A: display step / function when non-decision is possible). .

  In the state where the non-decidable display step / function (# 30A) is being executed, it is determined whether or not it is an operation state in which contact with the detection target T is detected (# 41). If it is not in the operation state (if there is no contact), the initial screen display step / function (# 10) is executed again. That is, when the contact between the detection target T and the touch display panel 2 is released in a state where the movable icon M belongs to the non-determined region R2, the display control unit 3 hides the movable icon M and selects it. The operation icon F corresponding to the icon S is displayed at the initial display coordinates D in the standard display state.

  If it is determined in the step / function (# 41) that the operation state is present (if there is contact), it is next determined whether or not the contact position (indicated coordinate P) belongs to the determination region R1 (# 43). When the touched position (indicated coordinate P) is not within the determined region R1 (in the non-determined region R2) in the operation state, the non-decidable display step / function (# 30A) is continued. In the operation state, when the contact position (indicated coordinate P) belongs to the determination region R1, the display control unit 3 displays the movable icon M and hides the selection icon S (# 30B: determination is possible).
