FIG. 1 is a block diagram of a portable game device to which the present invention is applied. FIG. 2 is a schematic diagram illustrating an example of a display mode on a display of a portable game device. FIG. 3 is a schematic diagram illustrating another example of a display mode on the display of the portable game device. FIG. 4 is a schematic diagram showing still another example of a display mode on the display of the portable game device.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a portable game device as a game machine constituting a computer. As shown in FIG. 2, the portable game machine 1 has a main body 2 made of a portable casing, and the main body 2 is provided with a display 3. The display 3 is a touch panel type input. The player also serves as the unit 5, and the player selects various objects such as a cursor, icons, and characters displayed on the display surface 3 a of the display 3 with a finger, and selects various objects corresponding to the objects. This processing can be performed on the portable game apparatus 1. Since the touch panel type input method is already known, detailed description thereof is omitted here. In the case of the portable game apparatus 1 shown in FIG. 1, all inputs are made by touching the display surface 3a of the display 3 with a finger.

As shown in FIG. 2, the portable game apparatus 1 has a main control unit 6, and the main control unit 6 has the touch panel type input unit 5, the display control unit 9, and the display 3 described above via the bus line 6. , A cursor movement control unit 10, a character selection determination unit 11, a character body movement control unit 12, a game execution control unit 13, a finger movement detection unit 15, a memory 16, and the like are connected. These components are all installed in the main body 2, and the portable game device 1 is carried when the player carries the main body 2. Note that the block diagram shown in FIG. 1 shows only the portion related to the present invention by way of example, and does not show the entire configuration of the actual portable game apparatus 1. The display control unit 9 constitutes an object display unit, and the cursor movement control unit 10 constitutes an object display position calculation unit and an object selection unit. The character selection determination unit 11 constitutes an object selection unit and a relative position calculation unit, and the character main body movement control unit 12 constitutes a display mode change unit, an object display position calculation unit, and an object separation display unit. Further, the finger movement detection unit 15 constitutes finger contact detection means, finger position calculation means, and object selection means.

In the portable game apparatus 1 shown in FIG. 2, in practice, a computer reads and executes a predetermined program stored in a memory (not shown), so that a CPU and a memory (not shown) are time-shared by multitasking. It will operate and perform the functions shown in each block shown in FIG. However, the portable game apparatus 1 can be configured with hardware corresponding to each block, and each block can be configured to be controlled by CPUs or MPUs provided in a distributed manner in each block. Is possible.

Since the portable game apparatus 1 has the above-described configuration, when a player plays a game, the touch panel type input unit 5 shown in FIG. 1 is operated to instruct the start of the game. In response to this, the main control unit 6 instructs the game execution control unit 13 to execute the game, and the game execution control unit 13 reads a predetermined game program GPR from the memory 16 and executes it.

In a game based on the game program GPR, for example, as shown in FIG. 2, while the two-dimensional field FLD is displayed on the display, the player moves and positions the cursor CS constituting the object in the claims to an appropriate position. There is work. This operation is usually performed by causing the player to press an arbitrary position on the display 3 to display the cursor CS on the display surface 3a and dragging the finger to the target position on the display surface 3a as it is. . Hereinafter, the movement positioning control of the cursor CS of the portable game apparatus 1 according to the present invention will be described.

For example, in a state where one or more characters CR are displayed on the display 3, when the player determines and instructs the game apparatus 1 to select the character CR that the player wants to select from among the characters CR, the player first displays the display 3. The finger 19 is placed at an arbitrary position on the display surface 3a with the fingertip 19a in contact with the display surface 2a. When the fingertip 19a is placed on the display surface 2a, the finger movement detection unit 15 detects that the finger 19 has come into contact with the display surface 2a, and notifies the cursor movement control unit 10 together with the coordinate position P1. The cursor movement control unit 10 inquires of the character selection determination unit 11 whether or not a specific character CR is currently selected by the player. In this state, since the specific character CR has not yet been selected, the character selection determination unit 11 notifies the cursor movement control unit 10 that the player has not selected the character CR.

In response to this, the cursor movement control unit 10 gives the display control unit 9 an upper position in FIG. 2 of the coordinate position P1 of the display surface 3a of the display 3 where the fingertip 19a is currently arranged (here, “upward”). Does not need to be exactly in the X axis + direction), that is, the coordinate position P2 is calculated and determined so that the translucent cursor CS is placed at the coordinate position P2 that is a predetermined distance L1 away from the fingertip 19a. The display control unit 9 is instructed. In response to this, the display control unit 9 displays a cursor CS at the coordinate position P2 on the display surface 3a of the display 3 as shown in FIG. 2, and the cursor CS is displayed on the display surface 3a by the fingertip 19a of the player. The player CS is displayed with a predetermined distance above (X axis + direction), and the player displays the cursor CS immediately below his / her fingertip 19a, making it difficult to understand the position of the cursor CS on the display surface 3a. Such a situation is prevented. The distance L1 is a value set in advance in a memory (not shown) in the cursor movement control unit 10, and the tip of the fingertip 19a arranged on the display surface 3a and the cursor CS are clearly separated from the player. The distance is set so as to be visible (for example, a gap SP of about 1 cm is generated on the display surface 3a).

In the above-described case, the object such as the cursor CS is at a position away from the player's fingertip by a predetermined distance in the X axis + direction (above the display display surface 3a), that is, the tip of the player's fingertip 19a and the object image. Although the case where the display is performed so that the gap SP is formed between them is described, the relative position of the object with respect to the fingertip 19a is not limited to the upper side of the display display surface 3a, and the gap SP is formed between the periphery of the finger 19 and the object. As long as the player can visually recognize the position of the object without being disturbed by the finger 19, any direction around the fingertip 19a may be used.

In this way, when the cursor CS is displayed on the display 20a, the player keeps the fingertip 19a in contact with the display surface 3a toward the coordinate position P3 where the character CR that the player wants to select is displayed. Move on the display surface 3a. The finger movement detection unit 15 repeatedly calculates the contact coordinate position P1 on the display 20a of the fingertip 19a at a constant time interval while monitoring the continuation of the contact between the fingertip 19a and the display surface 3a, and sends it to the cursor movement control unit 10. On the other hand, it outputs at regular time intervals. Based on the fluctuation of the coordinate position P1 of the fingertip 19a output from the finger movement detection unit 15, the cursor movement control unit 10 causes the cursor CS to always have a distance L1 in the X axis + direction with respect to the coordinate position P1. The display position P2 is calculated and determined, and the display control unit 9 is instructed to display the cursor CS at the display position P2.

Accordingly, the display control unit 9 always displays the cursor CS at a position P2 that is a predetermined distance above the fingertip 19a of the player, and the player points the fingertip 19a toward the coordinate position P3 where the character CR is displayed on the display surface 3a. Is moved and displayed in the direction of the coordinate position P1 while maintaining the direction parallel to the moving direction of the fingertip 19a in synchronization with the movement. As a result, the cursor CS always moves from the tip of the fingertip 19a of the player in the form displayed above the gap SP, so that the player can accurately change the current position of the cursor CS regardless of the movement of his fingertip 19a. Can be recognized.

The cursor movement control unit 10 maintains the relative position on the XY coordinates in a form in which the coordinate position P2 of the cursor CS maintains a fixed positional relationship on the display with respect to the coordinate position P1 of the current fingertip. Since the coordinate position P2 of the cursor CS is calculated and determined so as to have a shape, a setting is made such that the cursor CS does not exist in the X axis + direction of the fingertip 19a (for example, displayed on the side of the Y axis + or − side of the fingertip 19a) Even in the setting), display control is performed in such a manner that the fingertip 19a follows the sliding on the display surface 3a through the gap SP.

Thus, when the player moves the fingertip 19a in the direction of the character CR to be selected on the display surface 3a in the lower left direction in FIG. 2, the cursor CS also moves closer to the character CR in the lower left direction in FIG. Is displayed. In FIG. 2, only one character CR is displayed for easy understanding, but actually, one or more different characters CR are displayed on the display 20a. The player moves the fingertip 19a on the display surface 3a while checking the position of the cursor CS, and gradually brings the cursor CS closer to the character CR that he / she wants to select, and finally the cursor CS is displayed on the display 20a. Contact the CR image.

Then, the cursor movement control unit 10 detects that a certain character CR displayed on the display 20a is in contact with the cursor CS, and notifies the character selection determination unit 11 of the contact. In response to this, the character selection determination unit 11 specifies the character CR touched by the cursor CS. Since the game execution control unit 13 notifies the cursor movement control unit 10 and the character selection determination unit 11 of the name and the coordinate position of the character CR arranged on the display 20a by the game execution control unit 13, the cursor movement is performed. The detection of the contact between the cursor CS and the character CR in the control unit 10 and the specification of the character CR in contact with the cursor CS in the character selection determination unit 11 can be easily performed.

Thus, when the character CR touched by the cursor CS is specified together with its name and coordinate position P3, the character selection determination unit 11 selects the character CR selected by the player touching via the display control unit 9 with respect to the character CR. A circular selection mark SM centered on the cursor CS is displayed on the CR image. Thereby, the player can recognize on the screen of the display 20a that the character CR with which the cursor CS touches is selected. When the character CR is selected, the player releases the fingertip 19a from the display surface 3a, but the selected state is maintained and the display of the selection mark SM is continued. The character CR determined to be selected by the character selection determination unit 11 is notified to the cursor movement control unit 10 and the character body movement control unit 12.

When selecting the character CR, even when the cursor CS is moved toward the character CR to be selected, the target character CR is viewed while looking at the cursor CS displayed above the gap SP from the tip of the player's fingertip 19a. Since the cursor CS can be moved to the position where is displayed, the cursor CS can be accurately brought into contact with the target character CR. This is because when a plurality of other characters CR are arranged and displayed around the target character CR, the cursor CS is moved on the display surface 3a while avoiding the characters CR, This is particularly effective when it is necessary to move the cursor CS to the position where the target character CR is displayed.

When the player selects the character CR, the player moves the character CR selected by the player from the position P3 to the position P3 ′ shown in FIG. 3 on the field FLD in synchronization with the movement of the fingertip 19a of the player. When this is done (hereinafter, such movement is referred to as “drag movement”), the player brings the fingertip 19a into contact with an appropriate position on the display surface 3a of the display 20a. At this time, the player considers the position P3 where the current character CR is displayed and the position P3 ′ where the character CR is to be moved from now on. The position at which the field FLD can be observed, for example, the position P4 in FIG. 3 is selected, and the fingertip 19a is brought into contact with the position P4.

In addition, when the character CR to be moved is not yet selected, that is, when the selection mark SM is not arranged on the character CR, in addition to the method of moving the cursor CS and contacting the character CR, The player directly touches the image of the character CR displayed on the display surface 3a to detect the coordinate position of the fingertip 19a touched by the finger movement detection unit 15, and the character selection determination unit 11 detects the detected position. The coincidence between the coordinate position of the fingertip 19a and the coordinate position of the character CR displayed on the display surface 3a is detected, the selection of the character CR by the player is determined, and the image of the character CR is selected via the display control unit 9 The mark SM may be arranged and displayed.

When the player's fingertip 19a comes into contact with the display surface 3a, the finger movement detection unit 15 detects the contact of the player's fingertip 19a with the display surface 3a, and the contact of the fingertip 19a with the display surface 3a takes a certain amount of time (for example, If it continues for 0.1 second or more, it is determined that the drag movement of the character CR is instructed, and this is notified to the character main body movement control unit 12. In response to this, the character body movement control unit 12 displays the image (object) of the character CR in a translucent state as shown in FIG. 3 for the character CR currently selected by the player (the selection mark SM is displayed). The cursor CS and the character main body image (object main body) PC are displayed separately. That is, the cursor CS indicating the position P3 of the selected character CR is displayed as it is placed at the coordinate position P3 where the original character CR is placed, and the character body image PC (object body) is displayed on the cursor CS. The image is separated and displayed in the form moved to the coordinate position P5 moved upward, that is, by a predetermined distance L2 in the X axis + direction. The character main body image PC is not necessarily arranged above the cursor CS, and may be arranged anywhere around the cursor CS as long as the correspondence with the cursor CS can be taken.

As a result, the character CR selected by the player is displayed in a form in which the character main body image PC is floated on the cursor CS via the gap SP on the field FLD. As described above, the selected character CR is separately displayed on the cursor CS indicating the position of the character CR and the character main body image PC indicating the character CR itself. The exact position of the CR on the field FLD can be easily recognized. Since the character CR cursor CS and the character main body image PC are separated from each other so that the player can easily recognize the exact position of the character CR on the field FLD via the cursor CS, As long as the position of the character CR on the field FLD can be easily recognized, the character CR need not be displayed separately on the cursor CS and the character main body image PC. For example, when the player's fingertip 19a comes into contact with the display surface 3a, the character main body movement control unit 12 increases the transparency of the display of the character CR so as to be in a semi-transparent state, and transmits the character CR image. It is of course possible to perform control so that the position of the field FLD displayed below can be recognized.

When the character CR selected in this way is displayed separately on the cursor CS and the character main body image PC, the player moves the fingertip 19a in the form of sliding on the display surface 3a toward the position P4 ′. The finger movement detection unit 15 always calculates and detects the coordinate position of the fingertip 19a on the display surface 3a, and notifies the cursor movement control unit 10 and the character body movement control unit 12 of the result. Further, the cursor movement control unit 10 indicates the relative positional relationship of the coordinate position P3 of the character CR with respect to the coordinate position P4 when the player first touches the fingertip 19a on the display surface 3a. = Calculated and stored as (L4, L3). When the fingertip 19a moves on the display surface 3a, the display coordinates of the cursor CS are determined so that the relative positional relationship between the fingertip 19a and the cursor CR of the character CR is always the distance X, Y = (L4, L3). Displayed via the display control unit 9.

On the other hand, the character body movement control unit 12 moves the cursor movement control unit 10 on the display surface 3a while maintaining a certain distance X, Y = (L4, L3) by a predetermined distance L2 upward in FIG. The display position is calculated and determined so that the character main body image PC is displayed at the moved position, and is displayed via the display control unit 9. Thereby, the character main body image PC is displayed on the display 3 in a state of floating above the cursor CS via the gap SP.

In this state, when the player slides the fingertip 19a toward the position P3 ′ on the display surface 3a, the character CR is parallel to the movement trajectory TR of the fingertip 19a as shown in FIG. The CS and the character main body image PC are displayed while moving on the field FLD. The cursor CS is always displayed at a certain distance X, Y = (L4, L3) from the player's fingertip 19a. Therefore, the character CR is displayed separately on the cursor CS indicating the current position of the character CR and the character main body image PC displayed above (X axis + direction), and the position of the moving character CR on the field FLD is displayed. Can be clearly recognized by the cursor CS without being obstructed by the character main body image PC, it is easy to accurately move and position the character CR to the coordinate position P3 ′.

When the character CR reaches the coordinate position P3 ', the player moves the fingertip 19a away from the display surface 3a. Then, the finger movement detection unit 15 detects that the player's fingertip 19a has moved away from the display surface 3a and notifies the character body movement control unit 12 of it. In response to this, the character main body movement control unit 12 returns the character main body image PC which has been displayed so as to float above the cursor CS to the cursor CS. Thereby, the image of the character CR returns to the same image as the image of the normal character CR at the position P3 in FIG. 2 where the cursor CS and the character main body image PC are integrated.

In this state, when the player touches a decision button (not shown) displayed at an appropriate position on the display surface 3a of the display 3, the position of the character CR arranged at the position P3 ′ is fixed, and the game execution control unit 13 Recognizes that the character CR is arranged by drag movement at the determined coordinate position P3 ′, and advances the subsequent game. When the determination button is touched, the selection state of the character CR that has been selected by the player is canceled, and the character selection determination unit 11 displays the selection mark SM that has previously surrounded the character CR. stop.

Next, when it is desired to instantaneously move the character CR surrounded by the selection mark SM in the selected state from the coordinate position P3 to, for example, the vicinity of the coordinate position P6 as shown in FIG. 4, the player moves the fingertip 19a. The character CR is instantaneously brought into contact with the display surface 3a at the coordinate position P7 slightly below the coordinate position P6 to be moved. Then, the finger movement detecting unit 15 detects the contact of the fingertip 19a of the player with the display surface 3a, and at the same time, detects that the contact of the fingertip 19a with the display surface 3a is within a certain time (for example, 0.1 second). judge. Then, the finger movement detection unit 15 determines that the instantaneous movement of the character CR is instructed, and notifies the character main body movement control unit 12 to that effect.

In response to this, the character main body movement control unit 12 changes the display position of the object (cursor CS and character main body image PC) of the character CR that has been displayed at the coordinate position P3 so far to the coordinate position P7 of the fingertip 19a as shown in FIG. The coordinate position P6 separated by the distance L1 in the upward direction, that is, the + X-axis direction is calculated and determined, and the display controller 9 is commanded to move and display the character CR at the position. In response to this, the display control unit 9 displays the image of the character CR that has been displayed at the coordinate position P3 until then on the display 3 in a form moved to the coordinate position P6. In this case, since the image of the character CR is moved instantaneously, the player does not feel stress in the movement of the character CR.

Further, the image of the character CR at the moment of movement is displayed in the + X-axis direction of the player's fingertip 19a, that is, above the display surface 3a via the gap SP on the field FLD. The position can be easily recognized without being obstructed by the position of the fingertip 19a of the player.

In this state, when the player touches a decision button (not shown) displayed at an appropriate position on the display surface 3a of the display 3, the position of the character CR arranged at the position P6 is fixed, and the game execution control unit 13 Then, it is recognized that the character CR is arranged by the instantaneous movement at the determined coordinate position P6, and the subsequent game is advanced. When the determination button is touched, the selection state of the character CR that has been selected by the player is canceled, and the character selection determination unit 11 displays the selection mark SM that has previously surrounded the character CR. stop.
