  Next, with reference to FIG. 3 to FIG. 7, before describing a specific processing operation by the display form changing program executed in the game apparatus 1, the processing operation causes the first LCD 11 and the second LCD 12 to be processed. A display form example to be displayed will be described. In order to make the description concrete, an example of a display form will be described by taking an electronic dictionary in which the dictionary is converted into digital data and recorded on an electronic medium and viewed by the game apparatus 1 as an example. In this case, the electronic book data stored in the memory card 17 is obtained by converting the dictionary into digital data. FIG. 3 is a diagram showing a screen display example of an electronic dictionary displayed on the first LCD 11 and the second LCD 12. FIG. 4 is a diagram illustrating an example of a process for adding a marker to a part of display information displayed on the second LCD 12. FIG. 5 is a diagram for explaining a forward direction and a reverse direction with respect to character information. FIG. 6 is a diagram illustrating an example of a process for erasing a marker given to a part of display information displayed on the second LCD 12. FIG. 7 is a diagram illustrating an example of a process for turning part of display information displayed on the second LCD 12 into a hidden character or canceling the hidden character.

  In FIG. 3, when browsing the electronic book data obtained by converting the dictionary into digital data with the game apparatus 1, for example, an explanation for the word searched by the user is displayed as character information on the first LCD 11 and the second LCD 12. In the display example shown in FIG. 3, the meaning for the word selected by the user is displayed on the first LCD 11 as horizontally written character information, and the synonym for the word selected by the user on the second LCD 12 and the comparison thereof are written horizontally. Is shown as Various icons are displayed outside the lower column of the character information shown on the second LCD 12. When the user performs a touch operation on the touch panel 15 covering the upper surface of these icons, an operation corresponding to the icon can be performed. A marker icon Im is included as one of those icons. When the user touches the touch panel 15 on the marker icon Im, the mode shifts to the marker mode.

  When the marker mode is entered, the user can add a marker to any character in the character information displayed on the second LCD 12. As shown in FIG. 4, when a touch operation such as dragging the touch panel 15 on the character in the reading direction (direction a in the figure) is performed on the character to which a marker is to be added, the marker M1 (FIG. (Indicated by a hatched area 4) are sequentially given in accordance with the touch operation. Here, the character reading direction is a direction from right to left in horizontal writing as shown in FIG. 5, and is a direction from top to bottom in vertical writing. Hereinafter, the direction in which characters are read is referred to as the forward direction. Specifically, the touch operation is performed by touching (touching on) the stick 16 to the touch panel 15 from the position on the left side of the character “naturally” “self” and dragging it to the position on the right side of “ni”. When the stick 16 is released from 15 (touch-off), the marker M1 is given to the character “naturally”. The marker is expressed by adding a region painted with a color different from the background color of the other character information to the background of the selected character information in order to distinguish the selected character information from the other character information. As an example in which a marker is added and displayed on the second LCD 12, the selected character information is superimposed on a painted area representing the marker so that the user can visually recognize the character information. Note that the user can also add a plurality of markers by performing a touch operation of dragging the character information at a plurality of positions in the forward direction (see markers M1 to M4 in FIG. 7). Further, when the user performs a touch operation of dragging the horizontally written character information displayed on the second LCD 12 in an obliquely downward direction (left oblique direction in the case of vertically written character information), the downwardly oblique direction. Markers are assigned to all character information along the reading direction from the start point to the end point of the touch operation.

  In the marker mode, the user can delete any given marker. As shown in FIG. 6, when a touch operation such as dragging the touch panel 15 on a character with a marker to be erased in a direction opposite to the direction of reading the character (direction b in the drawing) is performed, The marker M1 provided on the character is sequentially erased in accordance with the touch operation. Here, as shown in FIG. 5, the direction opposite to the direction in which characters are read is a direction from right to left in horizontal writing, and a direction from bottom to top in vertical writing. Hereinafter, the direction opposite to the direction in which characters are read is simply referred to as the reverse direction. Specifically, the character “naturally” is touched on the right side of “N” of the character “Naturally” to which the marker M1 is attached, and touched to touch the touch panel 15 to the left side of “O” and touched off. The marker M1 assigned to is deleted. Note that when a touch operation in the reverse direction is performed on a part of the given marker, only the part of the marker is deleted. For example, by touching on the right side of “N” of the character “Naturally” with the marker M1 and touching off the touch panel 15 to the left side of “N”, the character “N” is added to the character “N”. A part of the marker M1 is deleted, and the marker M1 assigned to the character “natural” is continuously assigned and displayed. Note that when a reverse touch operation is performed on character information to which no marker is attached, the display form is not changed. Further, when the user performs a touch operation of dragging the horizontally written character information displayed on the second LCD 12 in an upward oblique direction (right oblique direction in the case of vertically written character information), the upward oblique direction is performed. All the markers attached to the character information along the direction opposite to the reading direction from the start point to the end point of the touch operation are deleted. In this way, the user can delete a marker by giving a marker by performing a touch operation of dragging the displayed character information in the forward direction, and by performing a touch operation of dragging in the reverse direction. It can be done easily.

  Furthermore, in the marker mode, the user can conceal (hide) the character to which the marker is attached. As shown in the operation from the upper diagram to the lower diagram in FIG. 7, when the touch panel 15 on the character to be concealed is touched twice among the characters to which the marker is attached, the character is concealed and displayed as a hidden character. Is displayed. Here, the operation of continuously touching the touch panel 15 is an operation of performing a touch-on-touch-off operation of touching and releasing the stick 16 on the touch panel 15 twice in a predetermined time, similar to so-called “double click”. Operation. Specifically, among the characters to which the markers M1 to M4 are assigned, by performing an operation of touching the character “naturally” to which the marker M1 is given twice in succession, the character “to which the marker M1 is given”. "Naturally" is concealed and becomes a face-down character. In the hidden character in the present embodiment, the selected character information is hidden and displayed by a marker that is a filled region. As an example of display on the second LCD 12 that conceals character information, a marker is superimposed on the character information to be concealed so that the user cannot see the character information. That is, the character information (marker M1 in the upper diagram of FIG. 7) to which the marker is attached and the character information of the obscure character (marker M1 in the lower diagram of FIG. 7) are reversed in the vertical relationship in which the marker and the character information are superimposed. It is.

  On the other hand, in the marker mode, the user can cancel the concealment of the character concealed by the marker. As shown in the operation from the lower diagram to the upper diagram in FIG. 7, when the touch panel 15 on the character that is desired to be hidden is touched twice among the characters hidden by the marker, the character is unmasked. Displayed as a character with a marker. Specifically, by performing an operation of touching the marker M1 that conceals the character twice in succession, the character “naturally” to which the marker M1 is attached is released and displayed. As an example of releasing the concealment of the character information and displaying it on the second LCD 12, the marker superimposed on the character information is moved below the character information so that the user can visually recognize the character information. In this way, the user can perform the same touch operation (two consecutive touch operations) on the marker, thereby performing the operation of turning the character information into a hidden character or canceling the hidden character, and each operation is easy. Can be done.

  In the marker mode, the user can cancel the concealment of characters concealed by the marker for a predetermined time. In the lower diagram of FIG. 7, when the touch-on-touch-off operation in which the touch panel 15 on the character concealed by the marker M1 is touched and released with the stick 16 is performed once, the concealment of the character is performed for a predetermined time (for example, 2 seconds). Only the character is released and displayed as a character with a marker (the state shown in the upper diagram of FIG. 7). In this way, the user can easily see the concealed character for a predetermined time by simply touching the marker for which the hidden character is desired to be released.

  Next, with reference to FIGS. 8 to 10, a specific processing operation by the display form change program executed in the game apparatus 1 will be described. FIG. 8 is a flowchart showing an operation in which the game apparatus 1 performs a display form change process by executing the display change program. FIG. 9 is a subroutine showing the detailed operation of the marker process in step 58 in FIG. FIG. 10 is a subroutine showing the detailed operation of the hidden character process in step 59 in FIG. Note that the program for executing these processes is included in the display form change program stored in the ROM 17a, and is read from the ROM 17a to the RAM 24 when the game apparatus 1 is turned on. It is executed by the CPU core 21.

  First, when a power source (not shown) of the game apparatus 1 is turned on, a boot program (not shown) is executed by the CPU core 21, whereby the display form changing program stored in the memory card 17 is stored in the RAM 24. Loaded. When the loaded display form change program is executed by the CPU core 21, the steps shown in FIG. 8 (abbreviated as “S” in FIGS. 8 to 10) are executed. By executing the display form change program, a book image or the like corresponding to the display form change program or the word selected by the user is drawn on the first LCD 11 and the second LCD 12. A detailed description is omitted, and here, a process of changing the display form mainly based on information input from the touch panel 15 will be described in detail.

  In FIG. 8, the CPU core 21 prompts the user to select display data (word), and the book image to be drawn on the first LCD 11 and the second LCD 12 in accordance with an operation signal from the operation switch unit 14 operated by the user. The display data for is selected (step 51). Next, the CPU core 21 reads display data selected from the electronic book data stored in the memory card 17 (step 52), and reads the book image (in accordance with the display data) on the first LCD 11 and the second LCD 12 (see FIG. 3) is displayed (step 53). Then, the CPU core 21 advances the processing to the next step.

  Next, the CPU core 21 determines whether or not the user has selected a marker icon (marker icon Im in FIG. 3) (step 54). Then, when the marker icon is selected, the CPU core 21 shifts to the marker mode and proceeds to the next step 55. On the other hand, if the marker icon is not selected, the CPU core 21 advances the process to the next step 61.

  In step 55, the CPU core 21 determines whether or not there is a touch input from the touch panel 15 according to the user's operation. When there is a touch input, the CPU core 21 uses coordinates on the image displayed on the second LCD 12 corresponding to the touch position where the touch panel 15 is currently touched (hereinafter referred to as touch coordinates) as touch-on coordinates. Is stored in the RAM 24 (step 56), and the process proceeds to the next step 57. On the other hand, if there is no touch input, the CPU core 21 proceeds to the next step 60.

  In step 57, the CPU core 21 determines whether or not the touch-on coordinates set in step 56 are within the marker display area. For example, in the display example shown in FIG. 7, if the touch-on coordinates are inside any of the painted areas of the markers M1 to M4, it is determined that the area is within the marker display area. Then, the CPU core 21 performs a marker process (step 58) when the touch-on coordinates are outside the marker display area, and performs a hidden character process (step 59) when the touch-on coordinates are within the marker display area. Proceed to next step 60. Detailed operations of the marker processing and the hidden character processing will be described later.

  In step 60, the CPU core 21 determines whether or not the user continues to select the marker icon (continues the marker mode). If the marker icon continues to be selected, the CPU core 21 returns to step 55 and repeats the process. On the other hand, when the marker icon is not selected in the above steps 54 and 60, the CPU core 21 determines whether another icon is selected (step 61). Next, when another icon is selected, the CPU core 21 executes a process according to the selected icon (step 62), and advances the process to the next step 63. On the other hand, if no other icon is selected, the CPU core 21 proceeds to the next step 63 as it is.

  In step 63, the CPU core 21 determines whether or not the user has selected another display data (word). When another display data is selected, the CPU core 21 returns to step 51 and repeats the process. On the other hand, when another display data is not selected, the CPU core 21 determines whether or not to end the dictionary display process (step 64). When ending the dictionary display process, the CPU core 21 ends the process according to the flowchart. On the other hand, when the dictionary display process is continued, the CPU core 21 returns to step 54 and repeats the process.

  Next, the marker processing in step 58 will be described with reference to FIG. First, the CPU core 21 determines whether or not the current touch coordinates are in the forward direction (see FIG. 5) in the displayed character information with respect to the touch-on coordinates set in step 56 (step 71). ). If the current touch coordinate is in the forward direction, the CPU core 21 displays a marker on the forward character information from the touch-on coordinate to the current touch coordinate (step 72; see FIG. 4), and the user touches off. It is determined whether or not (step 73). Then, the CPU core 21 proceeds to the next step 74 when the user touches off in step 73, and returns to step 71 and repeats the process when the touch operation is continued.

  In step 74, the CPU core 21 stores the current touch coordinates as touch-off coordinates in the RAM 24. Next, the CPU core 21 increments the marker counter that defines the marker number by 1 (step 75), and stores the marker area coordinates having the touch-on coordinates as the start point and the touch-off coordinates as the end points in the RAM 24 according to the marker numbers ( Step 76), the processing by the subroutine is terminated. The stored marker numbers and marker area coordinates will be described with reference to FIGS. 11 and 12.

  In FIG. 11, markers assigned to character information are managed by marker numbers, marker area coordinates, and a hidden character flag, and the data is stored in the RAM 24. Then, the CPU core 21 displays markers on the second LCD 12 based on these data stored in the RAM 24. The marker number is determined according to the marker counter value counted in step 75. The marker area coordinates are coordinate data indicating the display position of the marker superimposed on the book image displayed on the second LCD 12.

  As shown in FIG. 12, orthogonal X-axis and Y-axis coordinates are defined in the book image displayed on the second LCD 12. The marker area coordinates indicate the start point (Xs, Ys) and end point (Xe, Ye) of the marker with respect to the X-axis and Y-axis coordinates, respectively. For example, the position of the marker area coordinates of the marker M1 assigned to the character “naturally” is indicated by the start point (Xs1, Ys1) and the end point (Xe1, Ye1). Here, when the character information is written horizontally, the width of the marker M1 in the character height direction (the Y-axis direction in FIG. 12) is a constant value with a width W. For example, the width W is set according to the line width and line pitch of the character information. The marker M1 sets the start point (Xs1, Ys1) and the end point (Xe1, Ye1) to be the middle point of the width W, and has a width W from the start point (Xs1, Ys1) to the end point (Xe1, Ye1). A marker M1 is formed. When the character information is vertically written, the width of the marker M in the character width direction (X-axis direction in FIG. 12) is a constant value with the width W. Further, the start point (Xs, Ys) and the end point (Xe, Ye) may be set to be corners of the marker M.

  The hidden character flag is a flag for setting whether or not the character to which the marker is attached is concealed (hidden character). When the concealed character flag is “ON”, a marker is superimposed on the character information to conceal the character information. Further, when the concealed character flag is “OFF”, the character information is superimposed on the marker, and the concealment of the character information is released (visible by the user). In step 76, when a new marker is stored in the RAM 24, the turn-off flag is set to “OFF”.

  Returning to FIG. 9, in step 71, when the current touch coordinates are in the reverse direction (see FIG. 5) in the displayed character information with respect to the touch-on coordinates set in step 56, the CPU core 21 The process proceeds to step 77. In step 77, the CPU core 21 determines whether or not there is a marker display area on the character information in the reverse direction from the touch-on coordinate to the current touch coordinate. If there is a marker display area on the character information in the reverse direction, the process proceeds to the next step 78. On the other hand, if there is no marker display area on the character information in the reverse direction, the process proceeds to the next step 79 as it is.

  In step 78, the CPU core 21 erases the marker on the character information in the reverse direction from the touch-on coordinate to the current touch coordinate (see FIG. 6). Then, the CPU core 21 determines whether or not the user has touched off (step 79). If the touch is off, the process proceeds to the next step 80. If the touch operation is continued, the CPU core 21 returns to step 71. Repeat the process.

  In step 80, the CPU core 21 stores the current touch coordinates as touch-off coordinates in the RAM 24. Then, the CPU core 21 rewrites or deletes the marker area coordinates stored in the RAM 24 so that the marker on the character information in the reverse direction from the touch-on coordinates to the touch-off coordinates is deleted, and performs the processing according to the subroutine. finish.

  Next, the hidden character process in step 59 will be described with reference to FIG. First, the CPU core 21 determines whether or not the touch-on coordinates set in step 56 are within the hidden character display area (step 90). In the display example shown in FIG. 7, if the touch-on coordinate is within the area (marker M <b> 1 in the lower diagram of FIG. 7) in the painted area of the markers M <b> 1 to M <b> 4, the hidden character display area It is judged that. Then, the CPU core 21 advances the processing to the next step 91 when the touch-on coordinates are other than the hidden character display region, that is, within the marker display region of the hidden character flag “OFF”. On the other hand, if the touch-on coordinates are within the hidden character display area, the CPU core 21 advances the process to the next step 93.

  In step 91, the CPU core 21 determines whether or not the user has performed an operation of touching the touch panel 15 twice. If the CPU core 21 is an operation for two consecutive touches, the CPU 11 changes the marker-turned flag of the touch-operated marker to “ON” (step 92), and ends the processing of the subroutine. Since the marker is superimposed on the character information by changing the turn-on flag of the touch-operated marker to “ON”, the character information superimposed on the marker becomes invisible to the user (FIG. 7 lower diagram). reference). On the other hand, if the operation is not an operation of two consecutive touches, the CPU core 21 proceeds to step 71 (marker processing).

  FIG. 13 is a diagram showing an example in which the marker M1 shown in FIG. As is apparent from a comparison between FIG. 12 and FIG. 13, the marker M1 displayed in the hidden character is the same start point (Xs1, Ys1), end point (Xe1, Ye1), and marker with respect to the marker M1 shown in FIG. It is formed with a width W. The difference between the two is a form in which the vertical relationship in which the marker M1 and the character “naturally” are superimposed is reversed.

  In step 93, the CPU core 21 determines whether or not the user has performed an operation of touching the touch panel 15 twice. If the CPU core 21 is an operation for two consecutive touches, the CPU 11 changes the marker-turned flag for the touched operation to “OFF” (step 94), and ends the processing of the subroutine. Since the character information is superimposed on the marker by changing the turn-down flag of the touch-operated marker to “OFF”, the character information to which the marker is attached becomes visible to the user (the upper diagram in FIG. 7). reference). On the other hand, the CPU core 21 proceeds to the next step 95 when it is not an operation of two continuous touches.

  In step 95, the CPU core 21 determines whether or not the user has performed a touch-on / touch-off operation once on the touch panel 15. If the CPU core 21 does not perform the touch-on / touch-off operation once, the CPU core 21 proceeds to step 71 (marker processing). On the other hand, if the CPU core 21 is an operation for performing a touch-on-touch-off operation once, the CPU core 21 starts counting a counter that measures the time for releasing the concealment (step 96), and advances the processing to the next step.

  Next, the CPU core 21 changes the hidden character flag of the touch-operated marker to “OFF” to release the hiding by the marker (step 97), and for a predetermined time (for example, 2 seconds) measured by the counter. Wait for the progress (step 98). Then, when a predetermined time elapses due to the measurement of the counter (Yes in Step 98), the CPU core 21 sets the marker character of the touch-operated marker to “ON”, displays the marker as a marker character, and conceals the character. Then (step 99), the processing by the subroutine is finished. By the processing of these steps 95 to 99, the user can easily see the concealed character for a predetermined time simply by touching the marker for which the hidden character is desired to be released.

  As described above, according to the game device that executes the display form changing program of the present embodiment, it is possible to easily perform an operation of adding a marker to the displayed display information or displaying it in a hidden form. For example, when a marker is added to character information, the user performs a touch operation on the touch panel 15 to trace the character information to which the marker is to be added in the reading direction (forward direction) of the character information. On the other hand, when erasing a marker assigned to character information, the user performs a touch operation on the touch panel 15 to trace the marker to be erased in a direction opposite to the direction in which the character information is read (reverse direction). As described above, the marker can be easily added / erased only by reversing the direction of tracing the touch panel 15, and the operability of the user can be improved in accordance with the intuitive operation feeling of the user. Further, when the user performs a touch operation of touching the character information with the marker on the touch panel 15 for two consecutive times, the character information can be hidden. Further, when the user performs a touch operation of touching the character information displayed in a hidden character on the touch panel 15 twice, the concealment of the character information is released. In this way, the user can perform the same touch operation (two consecutive touch operations) on the marker, thereby performing the operation of turning the character information into a hidden character or canceling the hidden character, and each operation is easy. Can be done. Furthermore, when the user performs a touch operation of touching the character information displayed in a hidden character on the touch panel 15 once, the concealment of the character information is released for a certain period of time. In this way, the user can easily see the concealed character for a predetermined time by simply touching the marker for which the hidden character is desired to be released.

  In the above description, in order to make the description more specific, the change of each display mode has been described using specific operation procedures. However, these are examples, and the present invention is limited to these operation procedures. It goes without saying that there is nothing to do. For example, the marker is given by performing a touch operation of tracing the character information in the forward direction on the touch panel 15, and the marker is erased by performing the touch operation of tracing the character information in the reverse direction. It doesn't matter if it is erased. For example, the marker may be given by performing a touch operation of tracing character information in the reverse direction on the touch panel 15, and the marker may be deleted by performing a touch operation of tracing the character information in the forward direction. The direction in which the character information is first traced on the touch panel 15 is the direction in which the marker is applied, and the marker may be erased by performing a touch operation in which the character information is traced in the opposite direction. Further, the user may be configured to be able to select the direction in which the marker is applied and the direction in which the marker is deleted. In this case, the user can select the direction of applying the marker and the direction of erasing in accordance with the dominant arm or the like, which further improves usability.

  In addition, as described with reference to step 92 and FIG. 7, the marker that is displayed in the hidden character is only the marker touched by the user, but all the markers displayed on the second LCD 12 are displayed in the hidden character. It may be changed to. For example, all the markers M1 to M4 may be changed to the hidden character display by giving another touch operation (for example, three continuous touches) to any one of the markers M1 to M4 shown in FIG. In this case, it is possible to increase the number of variations that the user displays in a hidden character.

  In the above description, the character information is concealed / unconcealed when the user performs two consecutive touch operations on the marker, but the character information may be concealed / deconcealed by other operations. . For example, when the user performs a touch operation that traces the character information with the marker in the forward direction on the touch panel 15, the character information may be concealed and changed to a hidden character display. In this case, when the user performs a touch operation on the touch panel 15 in the reverse direction, the concealment of the character information is released.

  Further, in the above step 76, the explanation has been made that the hidden character flag is set to “OFF” when a new marker is stored in the RAM 24. However, the hidden character flag may be set to “ON”. In this case, simply by the user performing an operation of assigning a marker, a display in which the traced character is hidden by the newly assigned marker is performed. Further, the book image displayed on the second LCD 12 may include a marker display or a hidden character display in the default state. In this case, the marker displayed in the default state can be deleted by the same operation (S78) as described above, and the character information displayed in the default state is canceled by the same operation (S94) as described above. be able to.

  In the above-described embodiment, as an example of the liquid crystal display unit for two screens, a case where the first LCD 11 and the second LCD 12 that are physically separated from each other are arranged one above the other (in the case of two upper and lower screens) will be described. did. However, the configuration of the display screen for two screens may be other configurations. For example, the first LCD 11 and the second LCD 12 may be arranged on the left and right on one main surface of the lower housing 13b. In addition, a vertically long LCD having the same horizontal width as the second LCD 12 and having a vertical length twice as long (that is, a single LCD having a vertical display size of two screens) is placed below. It may be arranged on one main surface of the side housing 13b so that the first and second book images are displayed vertically (that is, displayed adjacently without the upper and lower boundary portions). In addition, a horizontally long LCD having the same vertical width as the second LCD 12 and having a width twice as long as the second LCD 12 is disposed on one main surface of the lower housing 13b, and the first and second in the horizontal direction. The book image may be displayed on the left and right (that is, displayed adjacently without the left and right borders). In other words, the first and second book images may be displayed by physically dividing one screen into two. Regardless of the form of the game image, the present invention can be similarly realized by disposing the touch panel 15 on the screen on which the second book image is displayed.

  In the embodiment described above, the touch panel 15 is integrally provided on the game apparatus 1. However, it goes without saying that the present invention can be realized even if the game apparatus and the touch panel are configured separately. Further, the touch panel 15 may be provided on the upper surface of the first LCD 11. Furthermore, although two display screens (first LCD 11 and second LCD 12) are provided in the above embodiment, the number of display screens may be one. That is, in the above-described embodiment, the touch panel 15 may be provided by using only the second LCD 12 as a display screen without providing the first LCD 11. In the above embodiment, the touch panel 15 may be provided on the upper surface of the first LCD 11 without providing the second LCD 12.

  Moreover, in the said Example, although the touch panel was used as an input means of the game device 1, other pointing devices may be used. Here, the pointing device is an input device for designating an input position and coordinates on the screen. For example, a mouse, a trackpad, a trackball, or the like is used as an input means, and is calculated from an output value output from the input means. The present invention can be similarly realized by using the information on the screen coordinate system.

  In the above embodiment, the touch panel 15 is integrally provided on the game apparatus 1, but an information processing apparatus (display control apparatus) such as a general personal computer that uses the touch panel as one of input means may be used.

  The display form changing program and the display control apparatus according to the present invention can easily perform an operation of changing the display form using a pointing device, and can process information such as a game device that displays display information such as character information on the display device. This is useful as a program or the like executed by the apparatus or its information processing apparatus.
