(3. Outline configuration of the terminal device according to the embodiment)
The terminal device 100 according to the present embodiment executes a music game and asks the player to operate the touch screen.

FIG. 3 shows an example of a game image of a music game executed by the terminal device 100. The game image 500 is an image displayed on the touch screen which is the output device 405. The game image 500 is a composite of a target image, a background image, and an image related to the progress of the game. The target image is an image showing an operation requested by the player. The target image includes a plurality of target objects TO1, TO2, TO3, TO4, and target positions TP1, TP2. The target positions TP1 and TP2 are fixed at the positions shown in FIG. 3 in the game image 500. The background image is a moving image (described later) showing a state in which a virtual camera arranged at a virtual viewpoint takes a picture in the virtual line-of-sight direction in the virtual space. The background image includes a character CH or the like arranged in the virtual space. Images relating to the progress of the game include a stamina gauge SG, a voltage gauge VG, and a message MG.

An orbit TR is assigned to each target object. The game image 500 includes two orbital TRs, and target positions TP1 and TP2 are arranged on each orbital. The target objects TO1, TO2, TO3, and TO4 move on the assigned orbit TR from above the game image 500 toward the target positions TP1 and TP2 in accordance with the rhythm of the music to be played.

There are a plurality of types of target objects, and the player is required to perform different operations depending on the types. For example, the target objects TO1 and TO4 require the player to tap the touch screen. Further, the target object TO2 requires the player to perform a tracing operation on the touch screen. The tracing operation is an operation of moving the touch position while keeping the finger, the touch pen, or the like in contact with the touch screen, like a slide or a flick. Further, the target object TO3 is formed by connecting two target objects TO3-1 and TO3-2 with a band, and while the target objects TO3-1 and TO3-2 pass through the target position TP1, the player touches the touch screen. Ask for a long press operation. The long-press operation is an operation in which the touch position is not moved while the finger, touch pen, or the like is in contact with the touch screen.

The player is required to perform an operation such as touching the screen at the timing when the target object completely overlaps the target position on each trajectory TR. Here, the timing at which the target object completely overlaps the target position on the trajectory associated with each target object, and the timing at which the player is requested to operate is referred to as the target time. That is, for the target objects TO1 and TO4, the timing when the target objects TO1 and TO4 completely overlap the target positions TP1 and TP2 is the target time point, and the operation of touching the target objects TO1 and TO4 is required at this point point. When the timing when the target object TO1 completely overlaps the target position TP1 and the timing when the target object TO4 completely overlaps the target position TP2 coincide with each other, the operations required by the target objects TO1 and TO4 are referred to as simultaneous pressing operations. Regarding the target object TO2, the timing when the target object TO2 completely overlaps the target position TP2 is the target time point, and at this point, the touch to the target object TO2 is started in the direction indicated by the arrow AR of the target object TO2. , It is required to perform a tracing operation. Regarding the target object TO3, the timing when the target object TO3-1 completely overlaps the target position TP1 and the timing when the target object TO3-2 completely overlaps the target position TP1 are the target time points. At the target point indicated by the target object TO3-1, touch the target object TO3-1 with a finger or the like, continue to touch the touch screen with the finger or the like, and touch the finger or the like with the touch screen at the target point indicated by the target object TO3-2. It is required to keep away from. Hereinafter, for the target object associated with the long press operation, the period from the target time point at which the touch should be started to the target time point at which the touch should be ended is referred to as a "target period". The target period of the target object to which the tap operation or the tracing operation is associated is a period including the target time point, and is a period from a time point before the target time point to a time point after the target time point. This predetermined period is arbitrarily set by the creator of the game. Further, the timing at which the target object completely overlaps the target position is set so as to be synchronized with the rhythm of the music.

The character CH represents a person placed in the virtual space and dances with a predetermined choreography. The predetermined choreography is, for example, a choreography that changes the posture so as to be synchronized with the rhythm of the musical piece to be played. Since the predetermined choreography and the target time point of the target object are set so as to be synchronized with the rhythm of the music, the change in the posture of the character CH dancing according to the predetermined choreography is the target time point (timing when the operation is required). Synchronize with. Although the game image 500 includes one character CH, a plurality of characters may be included.

The stamina gauge SG indicates the physical strength value of the character CH. The physical strength value is set to an upper limit value at the start of the music, and is a value that decreases each time the player performs an operation on the target object. The voltage gauge VG indicates the total value of evaluations for the operations performed by the player. The message MG indicates an evaluation of the operation performed by the player. For example, characters such as "JUST PERFECT", "PERFECT", "GREAT", "BAD", and "MISS" are displayed on the game image 500 according to the skill of the player's operation. "JUST PERFECT" has the highest evaluation, and thereafter, the evaluation goes down in the order of "PERFECT", "GREAT", "BAD", and "MISS".

The data related to the target object such as the type of the target object included in the game image 500 and the timing for requesting the operation, and the data related to the character CH are stored in the storage device 404 in association with the music. In addition, the evaluation result data for the player's operation is also stored in the storage device 404. These data may be stored in the game server 200.

FIG. 4 shows an outline configuration of the terminal device 100. The terminal device 100 includes a first display unit 101, a second display unit 102, a determination unit 103, and an evaluation unit 104. In the present embodiment, the CPU 401 and the output device 405 cooperate to function as the first display unit 101 and the second display unit 102, the CPU 401 functions as the determination unit 103, and the CPU 401 and the input device 407 In cooperation, it functions as an evaluation unit 104.

The first display unit 101 displays the target object on the touch screen so as to move along the trajectory set in the game image 500. Then, the first display unit 101 displays the target object so as to reach the target position set on the orbit at the target time point. Here, when the target object reaches the target position set on the orbit, it means that the target object completely overlaps the target positions TP1 and TP2 on the respective orbits TR. That is, the timing at which the target object reaches the target position set on the orbit is the target time point.

Taking the target object TO2 of the game image 500 of FIG. 3 as an example, the first display unit 101 moves the target object TO2 along the trajectory TR and sets the target object TO2 at the target position TP2 at the timing of requesting the player to perform a tracing operation. Display so that it completely overlaps with.

The second display unit 102 of FIG. 4 generates an image (described above) showing a state in which the virtual space in which the guide object is arranged is viewed from the virtual viewpoint in the virtual line-of-sight direction, that is, a background image.

The second display unit 102 changes at least one of the virtual viewpoint and the virtual line-of-sight direction so that the guide object is displayed in the background image in a manner associated with a predetermined operation at the target time point.

Here, the guide object is displayed in the game image in addition to the target object, and guides the operation required of the player.

For example, the guide object is at least a part of the character CH that dances with a predetermined choreography in the virtual space. A part of the character CH is, for example, a right hand, a left hand, or the like of the character CH, and all parts of the character CH are targeted. Since the predetermined choreography is set to be synchronized with the target time point, the change in the posture of the character CH is synchronized with the target time point, and the change in the movement of a part of the character CH is also synchronized with the target time point.

Further, the predetermined operation is an operation associated with the target object, for example, a tap operation on the touch screen, a tracing operation, a long press operation, a simultaneous press operation, and the like. The mode associated with the predetermined operation is, for example, a display mode in which the guide object approaches the guide object in the case of a tap operation, a display mode in which the guide object indicates the direction of the trace operation in the case of a trace operation, and a long press operation. A display mode in which the guide objects are displayed while the long press operation is required, and a display mode in which a plurality of guide objects are displayed and the guide objects are approached in the case of the simultaneous press operation. In the following, first, a display mode when the predetermined operation is a tracing operation will be described.

On the touch screen, the second display unit 102 displays a part of the character CH so as to move in the target direction indicated by the target object at the target time point. The target direction is the direction of the operation required of the player. For example, in the case of the target object TO2, the direction indicated by the arrow AR (right direction) is the target direction.

For example, assuming that a part of the character CH is the right hand, the second display unit 102 shows that the right hand of the character CH is the target object TO2 at the timing when the target object TO2 completely overlaps the target position TP2 in the game image 500. Display so that it moves in the direction indicated by the arrow AR.

Specifically, the second display unit 102 displays, on the touch screen, an image showing a state in which the virtual space in which the character is arranged is viewed from a virtual viewpoint in the virtual line-of-sight direction as a background image of the game image 500. By changing the virtual viewpoint and / or the virtual line-of-sight direction based on the determination of the determination unit 103 described later, a part of the character CH is displayed so as to move in the target direction at the target time point.

In the determination unit 103 of FIG. 4, the target object determines whether or not the movement associated with the target object and the movement of the guide object at the timing when the target object completely overlaps the target positions TP1 and TP2 match. Judgment is made before the timing when the target positions TP1 and TP2 completely overlap. That is, it is determined whether or not the movement of the operation associated with the target object and the movement of the guide object at the target time match at a timing before the target time. The timing at which the determination unit 103 makes a determination can be arbitrarily set by the creator of the game. When the determination unit 103 determines that the second display unit 102 does not match, the second display unit 102 changes the virtual viewpoint and / or the virtual line-of-sight direction.

Hereinafter, a method of changing the virtual viewpoint when the guide object does not move in the direction of the tracing operation indicated by the target object will be described.

FIG. 5A shows the positional relationship between the virtual space 600 viewed from above, the virtual viewpoint 601 and the virtual line-of-sight direction 602, and FIG. 5B shows the virtual space seen from the virtual viewpoint 601 in the virtual line-of-sight direction 602. A game image 500 showing the state of 600 is shown. The straight line 621 and the straight line 622 in FIG. 5A are for representing the position of the virtual viewpoint and the virtual line-of-sight direction. The intersection 623 of the straight line 621 and the straight line 622 indicates the initial position of the virtual camera, and the direction of the straight line 622 indicates the initial line-of-sight direction of the virtual camera. The virtual camera is located on the intersection 623, and the game image 500 shown in FIG. 5B shows a state in which the virtual camera has taken a picture from the virtual viewpoint 601 in the virtual line-of-sight direction 602.

FIG. 5A shows that the virtual viewpoint 601 is arranged in front of the character CH in the virtual space 600, and the virtual line-of-sight direction 602 is directed from the virtual viewpoint 601 to the character CH. Further, in the game image 500 of FIG. 5B, in the virtual space 600, the right hand 501 of the character CH dancing in choreography according to the rhythm of the music is before the timing when the target object TO2 completely overlaps the target position TP2. It shows that it is stationary at the timing of. Further, the character CH shall continue to stand still until the target object TO2 completely overlaps the target position TP2. In such a case, the determination unit 103 determines that the movement of the operation associated with the target object TO2 (tracing operation to the right) does not match the movement of the right hand 501 of the character CH (stationary).

When the determination unit 103 determines that the movement of the operation associated with the target object TO2 and the movement of the right hand 501 of the character CH do not match, the second display unit 102 determines that the movement of the right hand 501 of the character CH does not match. Than the timing when the tracing operation is required (the timing when the target object TO2 completely overlaps the target position TP2, the target time) so that the display position in the game image 500 moves in the direction of the tracing operation indicated by the target object TO2. Move the virtual viewpoint horizontally before a predetermined time. The predetermined time can be arbitrarily set by the creator of the game, and the predetermined time may be 0.

FIG. 6 (a) shows the virtual viewpoint 603 and the virtual line-of-sight direction 602 after the movement, and FIG. 6 (b) shows the state of the virtual space 600 as seen from the virtual viewpoint 603 after the movement in the virtual line-of-sight direction 602. Image 500 is shown. The second display unit 102 horizontally moves the virtual viewpoint in the direction opposite to the direction of the tracing operation indicated by the target object TO2. When the virtual viewpoint is changed from the virtual viewpoint 601 to the virtual viewpoint 603, as shown in FIG. 6B, the display position of the character CH's right hand 501 in the game image 500 is indicated by the arrow AR of the target object TO2. Can be moved in the same direction as (arrow 502). As a result, even when a part of the character is stationary, it is possible to make it appear that the part of the character is moving in the direction in which the tracing operation is required.

Next, a method of changing the virtual viewpoint and the virtual line-of-sight direction when the direction of the tracing operation indicated by the target object and the moving direction of the guide object are different will be described.

7 (a) and 7 (b) show an example of the game image 500, the virtual viewpoint and the virtual line-of-sight direction when the direction of the tracing operation indicated by the target object and the moving direction of the guide object are different. This example shows the state of the virtual space when the virtual viewpoint and the virtual line-of-sight direction are not changed according to the determination of the determination unit 103. FIG. 7A shows that the virtual viewpoint 601 is arranged in front of the character CH in the virtual space 600, and the virtual line-of-sight direction 602 is directed in the direction of the character CH. Further, in the game image 500 of FIG. 7B, the character CH arranged in the virtual space 600 dances in a choreography that matches the rhythm of the music, and the character at the timing when the target object TO2 completely overlaps the target position TP2. It shows how the right hand 501 of the CH moves in the direction of the arrow 503.

When the character is dancing as shown in FIG. 7B, the direction of the tracing operation indicated by the target object TO2 (the direction of the arrow AR) and the moving direction of the right hand 501 of the character CH, which is the guide object, at the time of the target. (Direction of arrow 503) is different. In this way, when the direction of the tracing operation indicated by the target object at the target time and the moving direction of the guide object are different, the second display unit 102 sets the virtual viewpoint and virtual as shown in FIG. 8A described later. Change the line-of-sight direction.

First, the determination unit 103 starts the determination at a timing before the target time point (for example, the timing when the target object TO2 is displayed on the game image 500). When the determination unit 103 determines that the movement of the operation associated with the target object TO2 does not match the movement of the right hand of the character CH at the time of the target, the second display unit 102 determines by the determination unit 103. Virtually, the direction of movement of the right hand 501 of the character CH is the same as the direction of the tracing operation indicated by the target object TO2 at a time point after the timing and a predetermined time before the target time point. Change the viewpoint and virtual line-of-sight direction.

FIG. 8A shows the changed virtual viewpoint 604 and the virtual line-of-sight direction 605, and FIG. 8B shows the game image 500 when the virtual viewpoint and the virtual line-of-sight direction are changed. The second display unit 102 moves the virtual viewpoint from the front (virtual viewpoint 601) to the back of the character CH (virtual viewpoint 604), and changes the virtual line-of-sight direction from the front direction of the character CH (virtual line-of-sight direction 602) to the character CH. Turn to the back direction (virtual line-of-sight direction 605). When the virtual viewpoint and the virtual line-of-sight direction are changed in this way, as shown in FIG. 8B, the movement of the right hand 501 of the character CH is in the same direction as the direction of the tracing operation indicated by the arrow AR of the target object TO2. It can be made to appear to move in the direction of (arrow 504).

When the back surface of the character CH is displayed on the game image 500 at the timing when the tracing operation is required and the right hand 501 of the character CH is opposite to the direction of the tracing operation, the second display unit 102 is virtual. The viewpoint is moved from the back surface of the character CH to the front surface of the character CH, and the virtual line-of-sight direction is directed from the back surface direction of the character CH to the front direction of the character CH.

Next, a method of changing the virtual viewpoint and the virtual line-of-sight direction when the guide object does not move in the direction of the tracing operation indicated by the target object will be described.

As shown in FIG. 5B, before the timing when the target object TO2 completely overlaps the target position TP2 (target time point), the right hand 501 of the character CH is stationary, and is continuously stationary even at the target time point. If so, the determination unit 103 determines that the movement of the operation associated with the target object TO2 does not match the movement of the right hand of the character CH. Then, the second display unit 102 rotates the virtual viewpoint around the character at a predetermined time before the target time so that a part of the character moves in the target direction at the target time, and during the rotation, Set the virtual line-of-sight direction in the direction of the character.

FIG. 9A shows the changed virtual viewpoint and virtual line-of-sight direction, and FIG. 9B shows a game image when the virtual viewpoint and virtual line-of-sight direction are changed. As shown in FIG. 9A, the second display unit 102 moves the virtual viewpoint from the virtual viewpoint 601 to the virtual viewpoint 606 by rotating the virtual viewpoint around the character CH, and sets the virtual line-of-sight direction as a character. The virtual line-of-sight direction 602 is changed to the virtual line-of-sight direction 607 while facing the CH direction. When the virtual viewpoint and the virtual line-of-sight direction are changed in this way, as shown in FIG. 9B, the arrow AR of the target object TO2 indicates the display position of the right hand 501 of the character CH in the game image 500. It can be moved in the same direction as the tracing operation direction (arrow 505).

Next, another method of changing the virtual viewpoint when the guide object does not move in the direction of the tracing operation indicated by the target object will be described. In the following, the second display unit 102 displays the guide object so as to pass through the target position at the target time point.

FIG. 10A shows that the virtual viewpoint 601 is arranged in front of the character CH in the virtual space 600, and the virtual line-of-sight direction 602 is directed in the direction of the character CH. Further, in the game image 500 of FIG. 10B, in the virtual space 600, the left hand 506 of the character CH dancing in choreography according to the rhythm of the music is before the timing when the target object TO2 completely overlaps the target position TP2. It shows that it is stationary. The character CH shall remain stationary until the target object TO2 completely overlaps the target position TP2.

As shown in FIG. 10B, the right hand 501 of the character CH comes to rest and the target object TO2 completely overlaps the target position TP2 at a timing before the timing when the target object TO2 completely overlaps the target position TP2. When the determination unit 103 continues to stand still until the timing, the determination unit 103 determines that the movement of the operation associated with the target object TO2 (tracing operation to the right) does not match the movement of the right hand of the character CH (stationary). When the determination unit 103 determines that they do not match, the second display unit 102 determines that the left hand 506 of the character CH passes the target position TP2 in the target direction at the target time, a predetermined time before the target time. To move the virtual viewpoint.

FIG. 11A shows the virtual viewpoints 608 and 609 and the virtual line-of-sight direction 602 after the movement, and FIG. 11B shows a game image when the virtual viewpoint is moved. As shown in FIG. 11A, the second display unit 102 moves the virtual viewpoint forward to a position where the left hand 506 of the character CH overlaps the target position TP2, as shown in FIG. 11A, before the target time point. The viewpoint 608) moves in the direction opposite to the direction of the tracing operation indicated by the target object TO2 at the target time (virtual viewpoint 609). When the position of the virtual viewpoint is changed in this way, as shown in FIG. 11B, the timing at which the tracing operation is required to trace the display position of the stationary character CH on the left hand 506 in the game image 500. It can be overlapped with the target position TP2 at a timing earlier than that, and it can be made to appear to move in the direction of the tracing operation at the timing when the tracing operation is required. As a result, the player can perform an accurate tracing operation by touching the left hand 506 of the character CH and moving the touch position in the same direction (arrow 507).

Next, another method of changing the virtual viewpoint when the direction of the tracing operation indicated by the target object and the moving direction of the guide object match will be described. In the following, when the determination unit 103 determines that the movement of the tracing operation associated with the target object and the direction of the movement of the guide object match, the second display unit 102 determines that the guide object is at the target time point. Is displayed so that it passes through the target position.

12 (a) and 12 (b) show an example of the game image 500 in which the direction of the tracing operation indicated by the target object and the moving direction of the guide object are the same, and the virtual viewpoint and virtual line-of-sight directions. This example shows the state of the virtual space when the virtual viewpoint and the virtual line-of-sight direction are not changed. FIG. 12A shows that the virtual viewpoint 601 is arranged in front of the character CH in the virtual space 600, and the virtual line-of-sight direction 602 is directed in the direction of the character CH. Further, in the game image 500 of FIG. 12B, at the timing when the target object TO2 completely overlaps the target position TP2, the left hand 506 of the character CH is in the same direction as the arrow AR of the target object TO2 (arrow 508). It shows how it moves in the direction). In this way, when the direction of the tracing operation indicated by the target object and the moving direction of the guide object are the same at the time of the target, the second display unit 102 displays the virtual viewpoint so that the guide object passes through the target position. To change.

First, the determination unit 103 starts the determination at a timing before the target time. When the determination unit 103 determines that the direction of the tracing operation associated with the target object TO2 matches the moving direction of the left hand 506 of the character CH, the second display unit 102 determines that the left hand 506 of the character CH is the target. The virtual viewpoint is moved before a predetermined time before the target time so that the object TO2 passes through the target position TP2 at the timing when the object TO2 completely overlaps the target position TP2.

FIG. 13A shows the virtual viewpoint 610 and the virtual line-of-sight direction 602 after the movement, and FIG. 13B shows the game image 500 when the virtual viewpoint is moved. As shown in FIG. 13A, the second display unit 102 sets the virtual viewpoint forward to a position where the left hand 506 of the character CH overlaps the target position TP2 and targets the target at a predetermined time before the target time. It moves horizontally in the direction opposite to the direction of the tracing operation indicated by the object TO2 (virtual viewpoint 610). Here, it is assumed that the predetermined time is set so that the timing when the target object TO2 completely overlaps the target position TP2 and the timing when the left hand 506 of the character CH starts to move in the arrow direction 508 coincide with each other. When the virtual viewpoint is changed in this way, as shown in FIG. 13B, the display position of the left hand 506 of the character CH in the game image 500 is targeted from the target position TP2 at the timing when the tracing operation is required. It can be moved in a direction, and the player can perform an accurate tracing operation by touching the left hand 506 of the character CH and moving it in the same direction (arrow 508).

Next, a display form when the predetermined operation is a tap operation will be described.

First, the determination unit 103 determines whether or not the movement of the operation (tap operation) associated with the target object matches the movement of the guide object at the time of the target. Here, in the determination unit 103, for example, when the guide object moves toward the front of the screen at the target time, the movement of the operation associated with the target object and the movement of the guide object at the target time are different. Judge that they match. When the determination unit 103 determines that the movement of the operation associated with the target object does not match the movement of the guide object at the target time, the second display unit 102 displays the target time on the touch screen. Then, change the virtual viewpoint so that it approaches the guide object. A specific example is shown below.

14 (a) and 14 (b) show a game image when the guide object (right hand 501 of the character CH) is stationary, and an example of the virtual viewpoint and the virtual line-of-sight direction at that time. FIG. 14A shows the positional relationship between the virtual space 600 viewed from above, the virtual viewpoint 601 and the virtual line-of-sight direction 602, and FIG. 14B shows the virtual space seen from the virtual viewpoint 601 in the virtual line-of-sight direction 602. A game image 500 showing the state of 600 is shown. The game image 500 of FIG. 14B shows a state in which the right hand 501 of the character CH is stationary in the virtual space 600 at a timing before the timing at which the target object TO1 completely overlaps the target position TP1. There is. It is assumed that the character CH remains stationary until the target object TO1 completely overlaps the target position TP1. In such a case, the determination unit 103 determines that the movement of the operation associated with the target object TO1 (tap operation) does not match the movement of the right hand 501 of the character CH (stationary).

FIG. 15A shows the virtual viewpoint 611 and the virtual line-of-sight direction 602 after the movement, and FIG. 15B shows the game image 500 when the virtual viewpoint is moved. When the determination unit 103 determines that the movement of the operation associated with the target object TO2 and the movement of the right hand 501 of the character CH at the time of the target do not match, the second display unit 102 displays the game image 500. At the timing when the target object TO1 completely overlaps the target position TP1, the virtual viewpoint is moved so that the right hand 501 of the character CH is displayed larger in the center of the game image 500 (virtual viewpoint 611). Then, when the target object TO1 finishes passing through the target position TP1, the second display unit 102 returns the virtual viewpoint to the original virtual viewpoint 601. In this way, when the virtual viewpoint is changed, the appearance of the character's right hand changes according to the timing of the tap operation, and it seems as if the character swings the right hand forward to guide the timing of the tap operation. Can be shown to.

Next, a display form when the predetermined operation is a long press operation will be described.

First, the determination unit 103 determines whether or not the movement of the operation (long press operation) associated with the target object matches the movement of the guide object during the target period. Here, for example, the determination unit 103 moves the display position so that the guide object approaches the front of the screen at the start of the target period, and the guide object is displayed while continuously approaching the screen during the target period. If so, it is determined that the movement of the operation associated with the target object matches the movement of the guide object at the time of the target. When the determination unit 103 determines that the movement of the operation associated with the target object does not match the movement of the guide object at the time of the target, the second display unit 102 displays the target period on the touch screen. During that time, change the virtual viewpoint to get closer to the guide object. A specific example is shown below.

16 (a) and 16 (b) show a game image when the guide object (right hand 501 of the character CH) is stationary, and an example of the virtual viewpoint and the virtual line-of-sight direction at that time. FIG. 16A shows the positional relationship between the virtual space 600 viewed from above, the virtual viewpoint 601 and the virtual line-of-sight direction 602, and FIG. 16B shows the virtual space seen from the virtual viewpoint 601 in the virtual line-of-sight direction 602. A game image 500 showing the state of 600 is shown. The game image 500 of FIG. 16B shows a state in which the right hand 501 of the character CH is stationary in the virtual space 600 at a timing before the timing at which the target object TO3-1 completely overlaps the target position TP1. Represents. It is assumed that the character CH remains stationary until the target object TO3-2 passes the target position TP1. In such a case, the determination unit 103 determines that the movement of the operation associated with the target object TO3 (long press operation) does not match the movement of the right hand 501 of the character CH (stationary).

FIG. 17A shows the virtual viewpoint 612 and the virtual line-of-sight direction 602 after the movement, and FIG. 17B shows the game image 500 when the virtual viewpoint is moved. When the determination unit 103 determines that the movement of the operation associated with the target object TO3 and the movement of the right hand 501 of the character CH do not match, the second display unit sets the target period in the game image 500. At the start point (timing when the target object TO3-1 completely overlaps the target position TP1), the virtual viewpoint is moved so that the right hand 501 of the character CH is displayed larger in the center of the screen (virtual viewpoint 612). Then, the second display unit 102 maintains the position of the virtual viewpoint 612 until the end time of the target period (the timing when the target object TO3-2 completely overlaps the target position TP1), and when the end time of the target period is reached. , Return to the original virtual viewpoint 601. When the virtual viewpoint is changed in this way, the appearance of the character's right hand changes according to the period for which the long press operation is required, and the character pushes the right hand forward to start and end the long press operation. You can make it look like you are guiding the timing.

Next, a display form when the predetermined operation is a simultaneous pressing operation will be described.

The simultaneous pressing operation is to perform a tap operation on a plurality of locations on the touch screen at the same time. In the case of the simultaneous pressing operation, the same number of guide objects as the number of guide objects required to be tapped at the same time are used. For example, when two target objects TO1 and TO4 are required to be pressed at the same time, the guide objects are determined to be two, the right hand 501 and the left hand 506 of the character CH.

First, the determination unit 103 determines whether or not the movement of the operation (simultaneous push operation) associated with the target object matches the movement of the plurality of guide objects at the time of the target. Here, for example, when a plurality of guide objects move toward the front of the screen at the target time, the determination unit 103 determines the movement of the operation associated with the target object and the movement of the guide object at the target time. Is determined to match. When the determination unit 103 determines that the movement of the operation associated with the target object does not match the movement of the guide object at the target time, the second display unit 102 displays the target time on the touch screen. Then, change the virtual viewpoint so that it approaches multiple guide objects. A specific example is shown below.

18 (a) and 18 (b) show a game image when the guide objects (right hand 501 and left hand 506 of the character CH) are stationary, and an example of the virtual viewpoint and the virtual line-of-sight direction at that time. FIG. 18A shows the positional relationship between the virtual space 600 viewed from above, the virtual viewpoint 601 and the virtual line-of-sight direction 602, and FIG. 18B shows the virtual space seen from the virtual viewpoint 601 in the virtual line-of-sight direction 602. A game image 500 showing the state of 600 is shown. In the game image 500 of FIG. 18B, the target time points of the target objects TO1 and TO4 are the same, and in the virtual space 600, the right hand 501 and the left hand 506 of the character CH are the target objects TO1 and TO4 are the target positions TP1. , Shows that it is stationary at a timing before the timing when it completely overlaps with TP2. It is assumed that the character CH continues to stand still until the target objects TO1 and TO4 completely overlap the target positions TP1 and TP2. In such a case, the determination unit 103 determines that the movement of the operation associated with the target objects TO1 and TO4 (simultaneous pressing operation) does not match the movement of the right hand 501 and the left hand 506 of the character CH (stationary). To do.

FIG. 19A shows the virtual viewpoint 613 and the virtual line-of-sight direction 602 after the movement, and FIG. 19B shows the game image 500 when the virtual viewpoint is moved. When the determination unit 103 determines that the movement of the operation associated with the target objects TO1 and TO4 does not match the movement of the right hand 501 and the left hand 506 of the character CH, the second display unit 102 displays the game. In the image 500, the virtual viewpoint is moved so that the right hand 501 and the left hand 506 of the character CH are displayed larger in the game image 500 at the timing when the target objects TO1 and TO4 completely overlap the target positions TP1 and TP2. Virtual viewpoint 613). Then, when the target objects TO1 and TO4 finish passing through the target positions TP1 and TP2, the second display unit 102 returns the virtual viewpoint to the original virtual viewpoint 601. In this way, when the virtual viewpoint is changed, the appearance of the character's right and left hands changes according to the timing of the simultaneous pressing operation, and the character shakes both hands forward to simultaneously press the tap operation. You can make it look like you are guiding the timing.

When the predetermined operation is a tap operation, a long press operation, or a simultaneous press operation, the processing by the determination unit 103 is omitted, and the second display unit 102 displays the guide object in a manner associated with the predetermined operation. , Virtual viewpoint and / or virtual line-of-sight direction. Further, the creator of the game can arbitrarily determine the criteria for the determination unit 103 to consider that the movement of the target object and the movement of the guide object match. Further, in the above specific example, only the virtual viewpoint is changed so as to approach a part or a plurality of parts of the character CH, but a part or a plurality of parts of the character CH as a guide object are hidden in the character's body. If it is difficult to see on the screen, change the virtual viewpoint and virtual line-of-sight direction. For example, the second display unit 102 rotates the virtual viewpoint around the character CH so that a part or a plurality of parts of the character CH are displayed in the center of the screen, and sets the virtual line-of-sight direction in the direction of the character CH. ..

Next, a method of changing the appearance of the guide object based on the evaluation of the player's operation will be described.

The evaluation unit 104 of FIG. 4 evaluates the operation performed by the player. For example, the evaluation unit 104 evaluates in five stages of "JUST PERFECT", "PERFECT", "GREAT", "BAD", and "MISS" according to the skill of the player's operation.

The second display unit 102 changes at least one of the virtual viewpoint and the virtual line-of-sight direction based on the evaluation by the evaluation unit 104.

Specifically, when the evaluation is equal to or less than a predetermined threshold value, the second display unit 102 changes at least one of the virtual viewpoint and the virtual line-of-sight direction before the predetermined grace time before the target time. The predetermined threshold value and the predetermined grace time are arbitrarily set by the creator of the game or the like. For example, a predetermined threshold value is set to "BAD", and a predetermined grace time is set to 3 seconds. When the evaluation of "BAD" is obtained for the operation on a certain target object and the next target object is the target object TO1 for which the tap operation is requested, the second display unit 102 displays 3 seconds before the target time of the target object TO1. The virtual viewpoint and / or the virtual line-of-sight direction is changed so that the right hand of the character CH moves to the front of the screen along the trajectory TR set in the game image 500 and overlaps with the target position TP1 at the target time. As a result, when the player cannot perform the operation accurately, the guide object can be displayed from an early stage to give the player time to prepare for the operation.

Further, the second display unit 102 may increase the number of guide objects when the evaluation is equal to or less than a predetermined threshold value. For example, it is assumed that when the operation of a certain target object is requested, the right hand 501 of the character CH is displayed as a guide object, and the evaluation of "BAD" is obtained for the operation on this target object. In this case, the second display unit 102 increases the number of characters to be displayed as the guide object when the next target object is displayed, and guides the same target time point with a plurality of characters. Further, the virtual viewpoint and / or the virtual line-of-sight direction may be changed so that a plurality of characters guide the target time point in order for each target object. This makes it easier for the player to recognize the guide object. In addition, it is possible to perform an effect in which a plurality of characters teach the operation.

Further, the second display unit 102 may highlight the guide object when the evaluation is equal to or less than a predetermined threshold value. For example, it is assumed that the right hand 501 of the character CH is displayed as a guide object when the operation of the target object TO2 indicating the tracing operation is requested, and the evaluation of "BAD" is obtained for the operation on this target object. In this case, the second display unit 102 highlights the right hand 501 of the character CH, such as holding a penlight, attaching a ring, or shining light, when the target object TO2 indicating the next tracing operation is displayed. I do. This makes it easier for the player to recognize the guide object.

Further, when the evaluation is equal to or less than a predetermined threshold value, the second display unit 102 may change at least one of the virtual viewpoint and the virtual line-of-sight direction so as to reduce the moving speed of the guide object. For example, it is assumed that the right hand 501 of the character CH is displayed as a guide object when the operation of the target object TO2 indicating the tracing operation is requested, and the evaluation of "BAD" is obtained for the operation on this target object. In this case, the second display unit 102 sets the speed at which the right hand 501 of the character CH moves in the direction of the tracing operation in the game image when the target object TO2 indicating the next tracing operation is displayed. At least one of the virtual viewpoint and the virtual line-of-sight direction is changed so as to be slower than the moving speed. This makes it easier to recognize the movement of the guide object.

Further, when the evaluation is higher than a predetermined threshold value, the second display unit 102 selects a guide object having a smaller size of the guide object. For example, it is assumed that the right arm of the character CH is displayed as a guide object when the operation of a certain target object is requested, and the evaluation of "JUST PERFECT" is obtained for the operation on this target object. In this case, the second display unit 102 changes the guide object to the right hand of the character CH when the next target object is displayed. When the evaluation higher than the predetermined threshold value is continuously obtained, the size of the guide object is gradually reduced. For example, the guide object is changed from the right hand to the neck of the character CH and from the neck to the wink. If the evaluation is equal to or less than a predetermined threshold value, the size of the guide object may be gradually increased. By doing this, by changing the size of the guide object based on the skill of the operation, it is possible to prevent advanced players from feeling that the guide object is annoying, and for beginners who need a guide. Can display the guide object in an easy-to-recognize manner.

The second display unit 102 may change the appearance of the guide object based on the difficulty level of the game selected by the player, not based on the evaluation. For example, when the difficulty level of the game is low, at least one of the virtual viewpoint and the virtual line-of-sight direction may be changed so as to reduce the moving speed of the guide object. Alternatively, the higher the difficulty of the game, the smaller the guide object may be selected.

Next, the setting method of the virtual viewpoint and the virtual line-of-sight direction will be described in detail.

First, the game image 500 is an image showing the state in the virtual space by perspective projection. That is, the game image 500 shows the result of projecting the state in the virtual space seen from the virtual viewpoint in the virtual line-of-sight direction onto the projection plane in the virtual space. The normal direction of the projection plane coincides with the virtual line-of-sight direction. In the following, we consider a situation in which a guide object (for example, the left hand 506 of the character CH) is projected to a predetermined position in the projection plane in order to guide the tracing operation (for example, a flick operation from left to right). ..

FIG. 20A shows a state in which the virtual space in which the character CH is arranged is viewed from above, and FIG. 20B shows a position (line segment) in which the left hand 506 of the character CH should be displayed in the projection surface Z. PQ) is shown. As shown in FIG. 20A, the left hand 506 of the character CH is choreographed so as to move from the point A to the point B in the virtual space. The points P and Q are fixed in the projection surface Z, and if the projection surface Z moves in the virtual space, the line segment PQ also moves accordingly. Here, it is assumed that the line segment AB and the line segment PQ are both horizontal. In order to make the movement from point A to point B most visible, that is, to be projected onto the projection surface Z in an easy-to-understand manner, the projection surface Z is arranged so that the line segment AB and the line segment PQ are parallel to each other. do it.

The projection plane Z in FIG. 20A is arranged so that the line segment AB and the line segment PQ are parallel to each other. When the projection plane is arranged in this way, the straight line AP passing through the points A and P and the straight line BQ passing through the points B and Q intersect. The intersection X where the two straight lines intersect is the position of the virtual viewpoint. Further, the normal direction N of the projection surface is defined as the virtual line-of-sight direction. If the lengths of the line segment AB and the line segment PQ match, parallel projection may be performed. That is, the position of the projection surface Z is moved so that the straight line AP and the straight line BQ are orthogonal to the projection surface Z, and the normal direction N of the projection surface Z is set as the virtual line-of-sight direction. When the line segment AB and the line segment PQ are not horizontal, the virtual viewpoint is rotated so that the projection surface Z is rotated in the normal direction N so that the line segment AB and the line segment PQ are parallel to each other.

(4. Operation of the terminal device according to the embodiment)
The operation of the terminal device 100 according to the present embodiment will be described. When, for example, the terminal device 100 executes the rhythm game shown in the game image 500, the terminal device 100 starts the control process shown in FIG.

The terminal device 100 displays a game image including a target image and a background image showing a state of being photographed in the virtual line-of-sight direction from a virtual viewpoint on the touch screen (step S101).

For example, the first display unit 101 moves the target objects TO1, TO2, TO3, and TO4 along the trajectory TR according to the data stored in the storage device 404, and at the timing when the player is requested to operate, the target objects TO1, TO2 , TO3 and TO4 are displayed so as to completely overlap the target positions TP1 and TP2. Further, the second display unit 102 displays an image (background image including the character CH) showing the state of the virtual space taken in the virtual line-of-sight direction 602 in the initial line-of-sight direction from the virtual viewpoint 601 which is the initial position of the virtual camera. To do.

The determination unit 103 determines whether or not the target object is displayed on the touch screen (step S102). When the determination unit 103 determines that the target object is displayed on the touch screen (step S102; YES), the movement of the operation requested by the target object matches the movement of a part of the character at the time of the target. It is determined whether or not the object is used (step S103). On the other hand, when the determination unit 103 determines that the target object indicating the operation is not displayed on the touch screen (step S102; NO), the determination unit 103 stands by as it is.

For example, the determination unit 103 determines whether or not the target object appears in the game image 500. When the target object TO2 appears in the game image 500, the determination unit 103 refers to the data stored in the storage device 404, and refers to the direction of the tracing operation requested by the target object TO2 and the target object TO2 at the target position TP2. The movement direction of the right hand 501 of the character CH at the timing of complete overlap is acquired, and it is determined whether or not they match. On the other hand, if the target object does not appear in the game image 500, it waits as it is.

In step S103, when the determination unit 103 determines that the movement of the operation requested by the target object matches the movement of a part of the character at the time of the target (step S103; YES), the second display unit 102 is virtual. Select a setting that does not change the viewpoint and the virtual line-of-sight direction (step S104). On the touch screen, a background image showing a state of being photographed from the same virtual viewpoint as in step S101 in the same virtual line-of-sight direction as in step S101 is continuously displayed. Then, the evaluation unit 104 evaluates the player's operation on the target object (step S105). Then, the process returns to step S101.

For example, as shown in FIG. 12B, when the direction of the tracing operation indicated by the target object TO2 and the moving direction of the right hand 501 of the character CH coincide with each other, the second display unit 102 displays FIG. Select a setting that does not change the virtual viewpoint 601 and the virtual line-of-sight direction 602 of a). As shown in FIG. 12B, the touch screen displays a picture taken from the virtual viewpoint 601 in the virtual line-of-sight direction 602 (the left hand 506 of the character CH moves in the arrow 508). Then, the evaluation unit 104 evaluates the player's operation on the target object TO2.

In step S103, when the determination unit 103 determines that the movement of the operation requested by the target object does not match the movement of a part of the character at the time of the target (step S103; NO), the second display unit 102 moves the player. It is determined whether or not the evaluation for the operation of is equal to or less than a predetermined threshold value (step S106). When the second display unit 102 determines that the evaluation of the player's operation is equal to or less than a predetermined threshold value (step S106; YES), the second display unit 102 changes the setting of the virtual viewpoint and / or the virtual line-of-sight direction (step S107). On the other hand, when the second display unit 102 determines that the evaluation of the player's operation exceeds a predetermined threshold value (step S106; NO), the second display unit 102 determines whether or not the current time has reached a predetermined time before the target time point (step S106; NO). S108).

For example, as shown in FIG. 5B, the right hand 501 of the character CH is stationary before the timing when the target object TO2 completely overlaps the target position TP2 (target time point), and is continuously stationary even at the target time point. If so, the determination unit 103 determines that the movement of the tracing operation indicated by the target object TO2 (tracing operation to the right) and the movement of the right hand 501 of the character CH (stationary) do not match. In this case, the second display unit 102 refers to the storage device 404 and evaluates the operation on the target object TO2 displayed (displayed in the past) before the currently displayed target object TO2 as “BAD”. "Judge whether it is less than or equal to. Assuming that the evaluation of "BAD" has been obtained for the operation on the target object TO2 displayed in the past, the second display unit 102 sets the moving speed of the virtual viewpoint slower than the preset moving speed. On the other hand, assuming that the evaluation of "GREAT" has been obtained for the operation on the target object TO2 displayed in the past, does the second display unit 102 reach a predetermined time before the target time point of the target object TO2? Judge whether or not.

In step S108, when the second display unit 102 determines that the current time has reached a predetermined time before the target time point (step S108; YES), the second display unit 102 displays a part of the character in a manner associated with the target object. In addition, the virtual viewpoint and the virtual line-of-sight direction are changed (step S109). Then, the second display unit 102 generates a background image of the changed virtual viewpoint and the appearance seen from the virtual line-of-sight direction and displays it on the touch screen (step S110). On the other hand, when the second display unit 102 determines that the current time has not reached a predetermined time before the target time (step S108; NO), the second display unit 102 stands by as it is.

For example, when the second display unit 102 determines that the target object TO2 has reached a predetermined time before the target time, the virtual viewpoint 601 is changed to the virtual viewpoint 603 as shown in FIG. 6A. Here, when the evaluation of the operation on the target object TO2 displayed in the past is equal to or less than a predetermined threshold value and the moving speed of the virtual viewpoint is changed in step S107, the second display unit 102 uses the changed moving speed. , Move from the virtual viewpoint 601 to the virtual viewpoint 603. If the evaluation of the operation on the target object TO2 displayed in the past exceeds a predetermined threshold value and the moving speed of the virtual viewpoint has not been changed, the second display unit 102 sets the moving speed at a predetermined movement speed. Move from the virtual viewpoint 601 to the virtual viewpoint 603. Then, the second display unit 102 generates a background image of the game image 500 shown in FIG. 6B, and the game image 500 is displayed on the touch screen. On the other hand, if the second display unit 102 determines that the current time has not reached a predetermined time before the target time of the target object TO2, the second display unit 102 waits as it is.

The second display unit 102 restores the virtual viewpoint and the virtual line-of-sight direction (step S111). Then, the process proceeds to step S105.

After the right hand 501 of the character CH is displayed so as to move in the direction of the arrow 502, the second display unit 102 returns to the original virtual viewpoint 601. The evaluation unit 104 evaluates the operation of the target object TO2, and the terminal device 100 continues to display the game image.
