Description

  The present invention relates to a display device, a display method, and a program suitable for enabling an operation of simultaneously pressing a plurality of positions on a game image using a plurality of touch screens.

  Conventionally, game machines using a resistive touch screen have been proposed. In such a touch screen, when a plurality of positions are simultaneously pressed by the player, the coordinates of the pressed positions cannot be physically detected, and the midpoint coordinates of those positions are detected. Therefore, various input methods for calculating the coordinates of the positions when a plurality of positions are pressed at the same time have been proposed.

  For example, in the technique disclosed in Patent Document 1 (paragraph 0034), when the player presses the second character image while pressing the first character image, the coordinates of the midpoints of the first and second pressed positions. Is output from the touch screen. The second pressing position is calculated by obtaining a position where the midpoint between the second pressing position and the first pressing position matches the output position from the touch screen.

JP 2006-244005 A

  However, these methods can calculate a plurality of positions pressed at the same time only under a predetermined condition. For example, the technique described in Patent Document 1 calculates the two positions on the condition that there is always a time difference between the first press and the second press. Therefore, when two points are pressed at the same time, the coordinate values of the two points cannot be obtained correctly. There is a demand for a technique that enables an operation of simultaneously pressing a plurality of positions without setting conditions.

  Further, in a portable game machine that adopts a typical folding format, only one of the upper and lower displays has a touch screen function. There are many requests to increase the touch screen area that can be input using two displays.

  The present invention solves the above-described problems, and a display device, a display method, and a display device suitable for enabling an operation of simultaneously pressing a plurality of positions on a game image using a plurality of touch screens. , Related to the program.

In order to achieve the above object, a display device according to a first aspect of the present invention includes a plurality of touch screens, an acquisition unit, a generation unit, and a display control unit.
Here, the plurality of touch screens display a given image and accepts a user's touch operation on the display surface of the image.
An acquisition part acquires the position of the 1 or more contact operation received by the 1 or more touch screen among several touch screens.

  The touch screen has, for example, a configuration in which a touch sensor panel is superimposed on a liquid crystal screen. When the user touches the surface of the touch screen with a finger, a touch pen, or the like, the acquisition unit acquires a coordinate value indicating a contact position on the touch screen where the contact is made. As the coordinate value, for example, a coordinate value with the upper left corner of the screen as the origin is used. On the other hand, when there is no contact, the acquisition unit acquires that fact.

Further, the generation unit generates an image to be given to each of the plurality of touch screens based on the acquired one or more positions.
The display control unit gives the generated image to each of the plurality of touch screens for display.

  In other words, the generation unit obtains what operation is designated by the user for the displayed image based on the acquired position information. Then, a game image to be displayed next is generated for each of the plurality of touch screens in order to advance the game in accordance with the designated user operation. The display control unit displays each generated image on each of the touch screens.

  Here, when the game images displayed on each of the touch screens are the same, as will be described later, the generation unit assumes that pressing on each of the acquired plurality of touch screens is performed on the same game image. To process. Therefore, the user can simultaneously press a plurality of positions on the game image by simultaneously pressing different positions on the touch screens. When the same game image is displayed on each of the touch screens, the image that the generation unit generates next for each touch screen is typically the same.

  In addition, even when the images displayed on the touch screens are not the same, if the predetermined positions of the touch screens are associated with each other, the user can press one point on each of the touch screens to play the game. A plurality of positions on the image can be pressed simultaneously.

  For example, a game image and an image indicating a home position are displayed on a main touch screen of a display device including a plurality of touch screens, and only the home position is displayed on another touch screen (sub-touch screen). The home position is, for example, a position that does not affect the progress of the game even if the user is in contact with the touch screen. Therefore, the user can rest the finger by touching the home position.

  In order to facilitate understanding, a case where there is one main touch screen (touch screen A) and one sub touch screen (touch screen B) will be described. The generation unit has pressed the main touch screen A. As for the coordinate value acquired by this, the coordinate value is used as it is. On the other hand, for the coordinate value acquired by pressing the sub touch screen B, the coordinate on the touch screen A corresponding to the coordinate value is obtained based on the relative position with respect to the home position. Accordingly, it is possible to designate a corresponding position on the main touch screen also by pressing the sub touch screen. Therefore, by simultaneously pressing the touch screen A and the touch screen B, it is possible to perform the same operation as simultaneously pressing a plurality of positions on the game image displayed on the touch screen A.

  Viewing each image displayed on multiple touch screens at the same time may distract and concentrate making it difficult to play the game. Therefore, in this way, by displaying only the home position on the touch screen B, the user need only pay attention to the position of the home position for the touch screen B, and is displayed on the touch screen A. You can concentrate on game images.

  Further, the generation unit may generate one image to be simultaneously given to the plurality of touch screens.

  That is, as described above, when the same game image is simultaneously displayed on each of the plurality of touch screens, the generation unit presses the pressed position on each of the plurality of touch screens, and the plurality of positions on the same image simultaneously press. Process as Therefore, according to the display device according to the present invention, the user can perform an operation of simultaneously pressing a plurality of positions on the game image using a plurality of touch screens.

  Note that the timing for displaying the game image on each of the touch screens may not be completely the same. That is, as long as the user can recognize that images are displayed at the same time, there may be a difference in the timing of displaying the images on the touch screens.

  Further, the generation unit corrects the position where the image to be given to each of the plurality of touch screens should be arranged on each of the plurality of touch screens based on the position acquired by the acquisition unit at a predetermined timing, and An image may be generated.

  Depending on the user, the position where the user can easily hold the game machine is different, and the position where the game machine is easily pressed is also different. Therefore, if the position on the touch screens A and B where the user rests his finger, that is, the home position is corrected so as to be placed at a position where the user can easily press the user's stress, the user's stress is eliminated and the operation is facilitated. Can be done.

  For example, at a predetermined timing, a time for the user to rest his / her finger at the home position is provided in the game, and the pressing position of the user is specified at the timing. At this time, if the specified position is different from the position of the previous home position, the position is set as a new home position. Or it is good also as a new home position by calculating | requiring the average of the last home position and the user's pressing position specified this time. And a production | generation part produces | generates the game image displayed next so that a home position may be arrange | positioned in the calculated | required new position.

  As a result, the user can easily perform the operation without feeling more stressed.

A display method according to another aspect of the present invention is a display method using a display device including a plurality of touch screens, an acquisition unit, a generation unit, and a display control unit.
Here, in the accepting step, the plurality of touch screens display the given image, and accepts the user's touch operation on the display surface of the image.
In the acquisition step, the position of one or more contact operations received by one or more touch screens among the plurality of touch screens is acquired.
In the generation step, an image to be given to each of the plurality of touch screens is generated based on the acquired one or more positions.
In the display control step, the generated image is given to each of the plurality of touch screens to be displayed.

  A program according to another aspect of the present invention is configured to cause a computer to function as the display device.

  The program of the present invention can be recorded on a computer-readable information recording medium such as a compact disk, flexible disk, hard disk, magneto-optical disk, digital video disk, magnetic tape, and semiconductor memory. The above program can be distributed and sold via a computer communication network independently of the computer on which the program is executed. The information recording medium can be distributed and sold independently of the computer.

  According to the present invention, it is possible to provide a display device, a display method, and a program suitable for enabling an operation of simultaneously pressing a plurality of positions on a game image using a plurality of touch screens.

The display device can be appropriately replaced with an element of a general computer or a game device as necessary, and these embodiments are also included in the scope of the present invention.

(Embodiment 1)
In the present embodiment, a case where display device 200 executes a so-called “mangled game” will be described as an example. The display device 200 typically includes two touch screens 201A and 201B, and a user plays a game by holding the display device 200 in both hands as shown in FIG. 2A. . As shown in FIG. 2B, the same game image is displayed on each of the touch screens 201A and 201B. In the game image, a home position 21 and a plurality of squares 22 arranged around the home position 21 are displayed, and the user displays the character 23 displayed on any one of the squares before the character 23 disappears. The purpose is to “tap” (press). Note that the home position is, for example, a position where the user rests his / her finger when no character is displayed.

  Here, when a plurality of characters are displayed at the same time, the user can strike the plurality of characters at the same time by simultaneously pressing different character positions displayed on the touch screens 201A and 201B. For example, in FIG. 3, the characters 23A and 23B can be hit simultaneously by pressing the character 23A with the touch screen 201A and the character 23B with the touch screen 201B.

  FIG. 4 shows a schematic configuration of display device 200 according to the present embodiment. As illustrated, the display device 200 includes touch screens 201A and 201B, an acquisition unit 202, a generation unit 203, and a display control unit 204.

  Here, the touch screens 201A and 201B accept a user's contact (pressing) operation. The first display unit 18A, the touch panel 19A, and the like function as the touch screen 201A, and the second display unit 18B, the touch panel 19B, and the like function as the touch screen 201B.

  The acquisition unit 202 acquires coordinate values on the touch clean indicating the position of the touch operation for each of the touch screens 201A and 201B. If there is no contact, the fact is acquired. Touch panels 19A and 19B in portable game machine 1 and touch panel controller 10f of processing control unit 10 function as acquisition unit 202.

  The generation unit 203 generates the same game image to be given to each of the touch screens 201A and 201B based on the one or more positions acquired by the acquisition unit 202. That is, the generation unit 203 obtains what operation is instructed by the user based on one or more pieces of acquired position information. Then, in accordance with the obtained operation instruction, a game image to be displayed next is read from the ROM 12a in the cartridge 12 and generated in order to advance the game. The processing control unit 10, the connector 11, the cartridge 12, and the like cooperate to function as the generation unit 203.

  The display control unit 204 displays the generated game image on each of the touch screens 201A and 201B at a predetermined synchronization timing. That is, the same game image is displayed on the touch screens 201A and 201B. The processing control unit 10 and the LCD controller 10e cooperate to function as the display control unit 204.

(Operation processing)
Next, an operation process of the display device 200 having such a configuration will be described with reference to FIG.

  First, display device 200 executes steps S101 and S102 for all touch screens (two touch screens 201A and 201B in the present embodiment).

  For example, based on the coordinate value acquired by the acquisition unit 202, the process control unit 10 first determines whether or not there is a press on the currently focused touch screen (step S101). If it is not pressed (step S101; N), the process control unit 10 executes the process for the next touch screen without executing step S102 for the touch screen. On the other hand, when the touch screen currently focused on is pressed (step S101; Y), the coordinate value is added to the queue for storing the coordinate value (step S102). The queue is stored in, for example, the WRAM 10d. In this way, Steps S101 and S102 are performed on all touch screens, and the coordinate values pressed on each touch screen are stored.

  Next, the generation unit 203 generates a game image to be displayed next based on the coordinate values stored in the queue and the current game state (step S103). Note that the generated game images are the same for the touch screens 201A and 201B.

  For example, if the current game state is a state in which the user's input is received (for example, a state where a muffled character is displayed on a square, etc.), the generation unit 203 uses the acquired coordinate values to calculate the game image. It is specified which part is designated by the user's pressing (step S103a; not shown). Of course, if nothing is stored in the queue, it is specified that there was no pressing by the user.

  On the other hand, when there is one coordinate value stored in the queue, the generation unit 203 specifies that the part in the game image displayed at the position specified by the coordinate position is specified by the user. When there are more than one coordinate value stored in the queue, the generation unit 203 assumes that one or more parts in the game image displayed at the position specified by the coordinate position are specified at the same time. Identify. In this embodiment, since the number of touch screens is two, a maximum of two coordinate values are stored in the queue. However, when the number of touch screens is N, the queue has a maximum of N. Coordinate values are stored.

  Next, the generation unit 203 generates a game image based on the position of the image specified by the user specified in this way (step S103b; not shown). For example, as described above, when the current game state is displaying a character to be hit and the position where the character is displayed on the touch screen is designated by the user, the generation unit 203 If it matches the position of the identified game image, it means that the user has successfully pressed the character. Therefore, the generation unit 203 generates, for example, a game image in which the character is crying from data stored in the ROM 12a or the like in the cartridge 12.

  On the other hand, when the position where the character is displayed does not match the position of the game image specified by the generation unit 203 as specified by the user, or when there is no user's press while the character is displayed This means that the user has failed to press the character. Therefore, the generation unit 203 generates, for example, a game image in which a character is laughing from data stored in the ROM 12a or the like in the cartridge 12.

  Naturally, if the current game state does not accept the user's press (for example, a state in which a movie is being played back), the generation unit 203 does not consider the coordinate values stored in the queue. The next game image may be generated in accordance with a game program stored in the ROM 12a or the like in the cartridge 12.

  As described above, the generation unit 203 generates a game image to be displayed next based on the contact position stored in the queue and the current game state.

  The game image generated in step S103 is stored in the VRAM 10c or the like. The display device 200 waits for a queue to be cleared or another process to be performed until a vertical synchronization interrupt occurs (step S104). When a vertical synchronization interrupt occurs, the display control unit 204 converts the image information stored in the VRAM 10c into a display signal and displays it on the touch screens 201A and 201B (step S105). That is, the display control unit 204 controls to display the same image on the touch screens 201A and 201B. Then, the process returns to step S101.

  Thus, according to the display device 200, the user can simultaneously press different positions in the game image by pressing different positions on the same game image displayed on each touch screen. .

(Embodiment 2)
In the above embodiment, the user operates the game according to the same game image displayed on each of all the touch screens (201A and 201B) included in the display device 200. However, viewing each game image displayed on one or more touch screens at the same time may distract and concentrate and make it difficult to play the game. Therefore, in the present embodiment, a display device 200 that realizes an operation system similar to that in the case of displaying and operating the same game image and that can maintain the user's concentration is described.

  In addition, since the component of the display apparatus 200 in this Embodiment is the same as the content shown in Embodiment 1, description is omitted.

  In the present embodiment, an example of a rattling game as in the first embodiment will be described. As shown in FIG. 6, the game image displayed on the touch screen (for example, the touch screen 201A) set as the main touch screen is the same as that of the first embodiment. That is, a game image including a home position 21 and a plurality of cells 22 arranged around the home position 21 is displayed on the main touch screen. The character to be hit by the user is displayed only on the main touch screen. On the other hand, an image including only the home position 21 is displayed on the sub-touch screen (for example, the touch screen 201B).

    The positions of the home positions of the main and sub touch screens can be set in advance before starting the game. In FIG. 6, the home position of the right sub touch screen is changed to the left main touch screen. An example is shown in which it is set at the lower right position from what is displayed. By making the position of the home position settable in this way, the user can adjust the home position according to a position where the game can be easily held.

  If the home position is moved greatly, the game image may not be displayed on the touch screen. Considering this, the range that can be set as the position of the home position may be limited.

  When it is desired to designate a certain part of the game image displayed on the main touch screen, the user may press the position where the part is displayed on the main touch screen as usual. Alternatively, the corresponding position on the sub touch screen may be pressed.

  For example, a case is assumed in which it is desired to designate the upper left square X of the home position in the game image displayed on the touch screen 201A shown in FIG. Even if the user presses an arbitrary point in the cell X on the touch screen 201A, the user is in the same position relative to the cell X with reference to the home position in X ′ surrounded by a dotted line on the touch screen 201B. Any point may be pressed.

(Operation processing)
The processing flow in the present embodiment is basically the same as steps S101 to S105 shown in FIG. That is, if there is a pressed coordinate value for each of the touch screens included in the display device 200 (step S101; Y), the process control unit 10 stores the coordinate value in a queue (step S102).

  However, in the present embodiment, the processing control unit 10 calculates the coordinate value obtained from the touch screen other than the main touch screen by calculating the coordinate value on the touch screen 201A corresponding to the coordinate value. Add the result to the queue.

For example, with reference to FIG. 8, a method for obtaining the position on the touch screen 201A corresponding to the pressing position Z on the touch screen 201B will be described.
As illustrated in FIG. 8A, the processing control unit 10 represents a representative position OB of the home position of the touch screen 201B (the representative position is, for example, the center of gravity) from the coordinate value indicating the pressing position Z on the touch screen 201B. A vector oz indicating a relative position from the home position to Z is obtained by subtracting the coordinate value. Next, as shown in FIG. 8B, the obtained vector Z is added to the coordinate value representing the position OA of the home position of the touch screen 201A. The coordinate value Z ′ obtained by the addition becomes a coordinate value on the touch screen 201A corresponding to the pressed position of the touch screen 201B. In this way, the processing control unit 10 maps all the coordinates acquired by the acquisition unit 202 to coordinate values on the main touch screen, and then stores them in the queue.

  Subsequently, the generation unit 203 performs a process similar to that in step S103a of the first embodiment on each of the coordinate values expressed as coordinate values on the main touch screen stored in the queue in this way. It is specified which part of the image is designated by the user's pressing. And the process similar to step S103b is performed and a game image is produced | generated based on the identified result. Here, the generated game image is for the main touch screen. On the other hand, for the sub-touch screen, an image indicating the home position is continuously generated.

  In the present embodiment, the VRAM 10c has separate areas for storing data output to the touch screens 201A and 201B, and these game images generated in step S103b are the areas of the corresponding VRAM 10c. Is remembered.

  In the example shown in FIG. 8B, since the user cannot hit any character, the next game image displayed on the main touch screen is an image in which the character is laughing.

  Subsequently, after waiting for vertical synchronization (step S104), when a vertical synchronization signal is generated, the display control unit 204 touches the game images for the main touch screen and the sub touch screen stored in the VRAM 10c, respectively. The information is displayed on the screen 201A and the touch screen 201B (step S105). Then, the process returns to step S101.

  As described above, according to the present embodiment, it is possible to simultaneously specify a plurality of positions of the same image, and by displaying only the home position on the sub-touch screen, the user can select the sub-touch screen. You only need to pay attention to the home position. Thereby, the user can concentrate on the game image displayed on the main touch screen.

  The main touch screen may be the touch screen 201B, and the sub touch screen may be the touch screen 201A. In this case, when the identification information of the touch screen 201A is acquired, the generation unit 203 may calculate a coordinate value on the touch screen 201B corresponding to the coordinate value.

  Although the present embodiment has been described above, the present invention is not limited to the above-described embodiment, and various modifications and applications are possible. Moreover, it is also possible to freely combine the components of the above-described embodiments.

  For example, although the above embodiment has described an example in which a wobbling game is executed, the display device according to the present invention is not limited to wobbling, and is a game that requires simultaneous pressing of a plurality of positions in a game image. Applicable.

  Moreover, in the said embodiment, although a display apparatus is provided with two touch screens, the number of touch screens may be more than two. At this time, in the second embodiment, there is a single main touch screen and a plurality of sub touch screens.

  Moreover, in the said embodiment, it correct | amends so that a home position may be moved to the position which a user has easily, and operability may be improved further.

  For example, in the above embodiment, while the character to be struck is not displayed, the user usually rests by returning his finger to the home position of the touch screen. Focusing on this point, at the timing when no character is displayed on the touch screens 201A and 201B (in the second embodiment, the touch screen 201A), the processing control unit 10 is based on the coordinate values acquired by the acquisition unit 202. The position pressed by the user for each of the touch screens is specified.

  At this time, if the position is different from the position of the previous home position (in the initial state, the home position is a predetermined position), the processing control unit 10 sets the position as a new home position. Alternatively, an average of the position of the previous home position and the position of the user's finger specified this time may be obtained and set as a new home position. By using the average of the position of the previous home position as in the latter case, the position where the user places the finger most frequently can be set as the home position. Note that the position of the home position is stored in, for example, the WRAM 10d. When a new home position is obtained, the WRAM 10d may be updated.

  In this way, the processing control unit 10 obtains a new home position position (coordinates). Then, the generation unit 203 generates the next game image so that the home position of the game image to be given to each touch screen is arranged at the position of the new home position obtained for each touch screen. .

  FIG. 9 shows an example in which the home position of the touch screen 201B, which is a sub-touch screen, is corrected in the second embodiment. In this example, the home position Y is corrected to the position Y ′, but the correction can also be applied to the main touch screen 201A. The home position correction may be applied to the first embodiment. If the home position is moved greatly, the game image may not be displayed on the touch screen. In consideration of this, the range for correcting the home position may be limited.

  In this way, the game is provided with a scene that allows the user to designate a reference position for gripping the user's game, represented by the home position, and correction is made so that the reference position is arranged at a position that is easy to press on the touch screen. Thus, operability can be improved.
