Description

  The present invention relates to an information display device, and more particularly, to an information display device capable of editing display contents based on contact with a touch panel or the like.

This type of information display device is widely used for presentations, meetings, classes, lectures, and the like, and has a large touch panel provided with a touch sensor on a display. When an image from an external device or the like is displayed on the display and the touch panel is touched with a user's finger or a touch pen, a figure such as a handwritten character or symbol can be written at the touched position.
When an operation mode in which characters and the like can be written (also referred to as an overwriting mode) is set, an application that executes the overwriting mode has an execution right. Therefore, even if the touch panel is touched to indicate a part of the display content, a line or the like is written at the touched location.

  Here, when the user wants to use an operation mode different from the current operation mode, there are an operation for canceling the current operation mode and an operation for transferring the execution right to an application that executes another operation mode. It is required separately and is inconvenient. Thus, for example, Patent Literature 1 discloses a technique that omits an operation for canceling the current operation mode and can automatically transfer the execution right from an application that executes the current operation mode to another application. .

JP 2004-78367 A

  However, according to Patent Document 1, even if the current operation mode can be canceled only by an operation for transferring the execution right to another application, the other operation mode can only be used, and the display content can be changed. I can't lock it. For this reason, during the presentation, even though the touch panel is only touched to indicate a part of the display content, the execution right is transferred to the application defined in the touched location, and the display content can be edited. If the mode is selected, a line or the like is written at the touched location, the input content moves to another position, or the current display content moves to the next page display content. There is a problem that an unintended operation is performed, which hinders the presentation.

  The present invention has been made in view of the above-described circumstances, and an object thereof is to provide an information display device that can smoothly make a presentation using a touch panel.

  In order to solve the above-described problem, the first technical means of the present invention includes an edit mode in which an image displayed on the touch panel can be edited, and a fixed operation that prohibits editing the displayed image and maintains the image. A determination unit that determines whether or not a predetermined position of the touch panel has been touched, and each time it is determined that the predetermined position has been touched, the editing mode and the fixed mode And a mode setting unit for switching between and a cabinet that presses a peripheral edge of the touch panel, and the predetermined position of the touch panel is formed in a strip shape along the outline of the cabinet. Device.

  According to a second technical means, in the first technical means, the predetermined position of the touch panel is displayed in a different manner between the edit mode and the fixed mode.

  According to the present invention, when a predetermined position on the touch panel is touched, the edit mode is easily switched to the fixed mode, and editing of the display content is prohibited and maintained as it is. For this reason, even if the touch panel is touched to indicate a part of the display content, the touch is not reflected in the display content, and it is not necessary to move from the current display content to the display content of the next page. Presentations are made smoothly. As a result, an information display device that is easy for the user to use can be provided.

  In addition, it is possible to touch a predetermined position of the touch panel regardless of the position of the user with respect to the display device. More specifically, when the display device is used in a vertical position like a blackboard, for example, the user can touch a predetermined position on the touch panel from either the left side or the right side of the display device. Moreover, when the display device is used in a flat position such as a desk, for example, it is possible to touch a predetermined position of the touch panel from any position on all four sides, so that convenience is further improved.

It is a front view of the information display apparatus by this invention. It is a block diagram showing the structure of the information display apparatus by this invention. 6 is a flowchart illustrating an operation at the time of mode switching according to the present invention. It is a figure explaining the mode switching by this invention. It is a figure explaining the mode switching by this invention. It is a figure explaining the mode switching by this invention.

  The information display device of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of an information display device according to the present invention. The information display device 1 has a touch panel 2 used for an electronic conference system. The touch panel 2 includes a touch sensor described later and, for example, a liquid crystal display, a rectangular LCD (Liquid Crystal Display) panel having a liquid crystal layer and a glass substrate, a protective glass, and, for example, LEDs arranged in a plane. Equipped with a direct backlight. The display may be a TFT liquid crystal or electronic paper, and the backlight may be an edge light type.

  The front peripheral edge and outer peripheral surface of the touch panel 2 are pressed by a frame-shaped front cabinet 11, and the back surface of the touch panel 2 is covered by a box-shaped rear cabinet (not shown). The front cabinet 11 corresponds to the cabinet of the present invention. The touch panel 2 is configured to be installable on a floor of a room via a floor stand 4, for example.

  FIG. 2 is a block diagram showing the configuration of the information display device according to the present invention. The information display device 1 includes a touch panel 2 and an information processing device 3. The touch panel 2 includes, for example, a transparent resistive film type touch sensor 10 and the liquid crystal display 12 described above, and is formed by providing the touch sensor 10 on the display 12. The touch sensor 10 is a sensor that detects contact with a finger or a touch pen. The detection method may be constituted by an infrared camera method, an infrared blocking detection method, a capacitance method, an electromagnetic induction method, or the like.

Based on an instruction from the information processing apparatus 3, for example, an image of a document is displayed on the display 12. The display 12 is set with a display orthogonal coordinate system, and pixels are arranged in a matrix along the coordinate system. The position of the pixel is output to the information processing device 3 and stored in the storage unit 21, for example.
On the other hand, the touch sensor 10 has a transparent electrode, and an orthogonal coordinate system for input is set for the transparent electrode. This orthogonal coordinate system corresponds to the orthogonal coordinate system for display.

In addition to the storage unit 21, the information processing device 3 includes a control unit 20, a contact determination unit 22, a mode setting unit 23, an image editing unit 24, an I / F 25, and the like, which are connected via a bus 26.
The control unit 20 includes, for example, one or a plurality of CPUs (Central Processing Units) and the like, and loads various programs and data stored in, for example, a ROM of the storage unit 21 into the RAM. Run the program. As a result, the overall operation of the information display device 1 is controlled based on the content of the instruction from the user.

Further, the control unit 20 causes the display 12 to display a GUI (graphical user interface) for operating the information display device 1.
The contact determination unit 22 detects a touch position on the touch panel 2 or a touch operation on the touch panel 2 such as a single tap or a flick. Further, the contact determination unit 22 can determine whether or not the user touches a predetermined position on the touch panel 2 to be described later based on the detection result of the touch position and the operation. Detection results and determination results are output to the mode setting unit 23. The contact determination unit 22 corresponds to the determination unit of the present invention.

  When the mode setting unit 23 receives the detection result from the contact determination unit 22, the mode setting unit 23 converts the detection result into the orthogonal coordinate system for display and outputs it to the image editing unit 24. Image data such as handwriting is stored in the storage unit 21. The image displayed on the touch panel 2 can be edited based on, for example, input from the keyboard to the input unit 27 in addition to the input to the touch panel 2, and this data is also stored in the storage unit 21.

  Further, when the mode setting unit 23 receives a determination result indicating that the predetermined position has been touched from the contact determination unit 22, the mode setting unit 23 changes the current operation mode (for example, edit mode) to another operation mode (for example, edit mode) (described later). For example, the image editing unit 24 performs processing in accordance with the operation mode after switching, specifically, processing specified for drawing at the touch position or touch operation when the editing mode is set. To instruct. Note that the mode setting unit may determine whether or not the touch panel 2 has touched a predetermined position, and may switch the operation mode.

In response to a command from the mode setting unit 23, the image editing unit 24 calls image data such as material and handwriting from the storage unit 21, and according to a predetermined program stored in the ROM, the image of the material and the image such as handwriting Are combined with the display 12. Thereby, the user of the information display device 1 can see the combined image on the touch panel 2.
Note that the control unit 20 can be connected to an external device (not shown) such as a multifunction peripheral or a personal computer (PC) via the I / F 25. For the connection, methods such as short-range wireless communication, network connection, and serial connection can be used. The information display device 1 may be equipped with a PC.

FIG. 3 is a flowchart for explaining the operation at the time of mode switching according to the present invention, and FIGS. 4 to 6 are diagrams for explaining the mode switching according to the present invention.
When editing based on the input to the touch panel 2, the contact determination unit 22 determines whether or not the user is touching a predetermined position of the touch panel 2, for example, near the outline of the touch panel 2 (step S <b> 101 in FIG. 3). Specifically, as shown in FIG. 4A, the mode switching button 14 is formed in a strip shape along the contour line of the front cabinet 11. For this reason, it becomes possible to touch the mode switching button 14 regardless of the position of the user with respect to the touch panel 2.

  When the user touches the mode switching button 14 (YES in step S101 in FIG. 3), the mode setting unit 23 determines whether or not the currently set operation mode is the edit mode (step S102). When the mode is the edit mode (YES in step S102), the mode setting unit 23 switches to the fixed mode (step S103), and locks the display content of the touch panel 2 when the mode switch button 14 is touched.

  More specifically, when the fixed mode is set, as shown in FIG. 4B, the user's finger touches the area inside the mode switching button 14, for example, the diagonally lower right direction from the center position of the touch panel 2. If it continues, the contact determination part 22 will detect this contact state. However, the mode setting unit 23 does not instruct the image editing unit 24 to process the touch panel 2. As a result, even if the finger is kept touched, the display content of the touch panel 2 remains the display content at the time when the fixed mode is set, for example, addition of a line accompanying touch on the touch panel 2 or writing of deletion is performed. Maintained without.

  Alternatively, as shown in FIG. 5A, when the fixed mode is set by touching the mode switching button 14, for example, as shown in FIG. Even if the tap is detected and this state is detected by the contact determination unit 22, the mode setting unit 23, for example, performs a process of shifting from the display content at the time when the fixed mode is set to the display content of the next page. Do not instruct. Therefore, even if the touch panel 2 is single-tapped, as shown in FIG. 5C, the display content of the touch panel 2 remains the same as the display content when the fixed mode is set.

  As described above, when the mode switching button 14 is touched, the editing mode is switched to the fixed mode, the editing of the display content is prohibited, and the display content at the time when the button 14 is touched is displayed as it is. Therefore, even if the touch panel 2 is touched to indicate a part of the display content, the touch on the touch panel 2 is not reflected in the display content, and the current display content does not need to move to the display content of the next page. Therefore, the presentation using the touch panel 2 can be performed smoothly.

  Further, when the mode switching button 14 is touched to switch from the editing mode to the fixed mode, the mode setting unit 23 changes the button 14 from the color (for example, light blue) set for the editing mode to the fixed mode. The displayed color (for example, light red) is displayed (step S104 in FIG. 3). If the editing mode and the fixed mode are displayed in different colors, the user can easily recognize the current mode.

On the other hand, when the currently set operation mode is the fixed mode (NO in step S102 in FIG. 3), the mode setting unit 23 switches to the edit mode (step S105). The display contents locked by the setting of the fixed mode can be edited based on the touch on the touch panel 2.
As a result, as shown in FIG. 4C, when the user's finger continues to touch the touch panel 2, for example, in the diagonally downward right direction from the center position, the mode setting unit 23 performs processing on the display content to the image editing unit 24. For example, a line is written at a position where the finger continues to be touched.

Alternatively, when the edit mode is set, as shown in FIG. 5B, for example, when the center position of the touch panel 2 is single-tapped with the user's finger, the mode setting unit 23 is defined as a single tap at this position. The image editing section 24 is instructed to display the display content of the next page as shown in FIG. 5D, for example.
When the mode is switched from the fixed mode to the edit mode, the mode switching button 14 displays the color set for the edit mode (for example, light blue) from the color set for the fixed mode (for example, light red). (Step S106 in FIG. 3).

  Alternatively, as shown in FIG. 6A, when the first window 31 is displayed on the touch panel 2 in front of the second window 32 and the fixed mode is set, the user switches the mode switching button 14. Touch to switch to edit mode. Next, as shown in FIG. 6B, when the user touches an area inside the mode switching button 14, for example, the second window 32, the second window 32 is displayed in front of the first window 31. The

  Subsequently, as shown in FIG. 6C, when the user touches the mode switching button 14, the mode is switched to the fixed mode. Thus, when the second window 32 is described, even if the user touches not only the second window 32 but also the first window 31, as shown in FIG. It remains unchanged from the first window 31 and the touched content is not reflected.

  Thus, every time the mode switching button 14 is touched, the edit mode and the fixed mode can be easily switched. Therefore, even when the editing mode is normally set, when it is desired to explain while pointing to the current display content, the mode switching button 14 is touched to set the fixed mode. Thereafter, when it is desired to input a line or the like to the current display content for explanation, or to advance to the next page, the mode change button 14 may be touched to set the edit mode.

  In the above embodiment, the mode switching button 14 is identified by color. However, when the fixed mode is set, for example, the mode switching button may be displayed with a hatched pattern or the like, or characters or symbols of “fixed mode” may be displayed on a part of the mode switching button.

As described above, the embodiments of the present invention have been described. The present invention includes an edit mode in which an image displayed on the touch panel can be edited, and a fixed mode in which editing to the displayed image is prohibited and the image is maintained. A determination unit that determines whether or not a predetermined position of the touch panel has been touched, and each time it is determined that the predetermined position has been touched, the edit mode and the fixed mode are And a mode setting unit for switching.
Thus, when a predetermined position on the touch panel is touched, the edit mode is easily switched to the fixed mode, and editing of the display content is prohibited and maintained as it is. For this reason, even if the touch panel is touched to indicate a part of the display content, the touch on the touch panel is not reflected in the display content, and it is not necessary to move from the current display content to the display content of the next page. The presentation using the information display device is smoothly performed. As a result, an information display device that is easy for the user to use can be provided.

Moreover, it has a cabinet which presses the periphery of the said touch panel, The said predetermined position of the said touch panel may be formed in strip | belt shape along the outline of the said cabinet. This makes it possible to touch a predetermined position on the touch panel regardless of the position of the user with respect to the display device.
Further, the predetermined position of the touch panel can be displayed in a different manner between the edit mode and the fixed mode. In this way, if the editing mode and the fixed mode are displayed in different colors, the user can easily recognize the current mode.
