[1. Embodiment]
Hereinafter, an example of an embodiment of the present invention will be described in detail with reference to the drawings. The game device according to the embodiment of the present invention is realized by, for example, a home game machine (stationary game machine), a portable game machine, a mobile phone (smart phone), a personal digital assistant (PDA), a personal computer, or the like. Here, a case where the game device according to the embodiment of the present invention is realized by a consumer game machine will be described.

  FIG. 1 is a diagram illustrating a state of a player playing a game. As shown in FIG. 1, the player 100 is located in front of the position detection device 1, for example. The position detection device 1 and the game device 20 are connected so that data communication is possible.

[2. Operation of position detection device]
First, the position detection apparatus 1 will be described. The position detection device 1 generates player position information related to the position of the player in the three-dimensional space. In the present embodiment, a case will be described in which the position information of the player includes information regarding the positions of a plurality of parts of the player 100. The part of the player 100 is, for example, the head or both arms.

  As shown in FIG. 1, the position detection device 1 includes, for example, a CCD camera 2, an infrared sensor 3, a microphone 4 including a plurality of microphones, and the like.

  The CCD camera 2 is a known camera equipped with a CCD image sensor. The CCD camera 2 generates a captured image (for example, an RGB digital image) obtained by capturing the player 100 at a predetermined time (for example, every 1/60 seconds), for example.

  FIG. 2 is a diagram illustrating an example of a captured image generated by the CCD camera 2. As shown in FIG. 2, the photographed image includes, for example, a player 100. An Xs axis and a Ys axis that are orthogonal to each other are set in the captured image. For example, the upper left of the photographed image is the origin Os (0, 0). In addition, for example, the lower right corner of the captured image is set as coordinates Pmax (Xmax, Ymax). The position of each pixel corresponding to the captured image is specified by two-dimensional coordinates (Xs-Ys coordinates) assigned to each pixel.

  The infrared sensor 3 includes, for example, an infrared light emitting element and an infrared light receiving element (for example, an infrared diode). The infrared sensor 3 detects reflected light obtained by irradiating infrared light. The infrared sensor 3 measures the depth of the subject (for example, the player 100) based on the detection result of the reflected light.

  The subject depth is a distance interval between the measurement reference position and the subject position. The measurement reference position is a position serving as a reference when measuring the depth (depth) of the position of the player 100. The measurement reference position may be a predetermined position associated with the position of the position detection device 1, for example, the position of the infrared light receiving element of the infrared sensor 3. The infrared sensor 3 measures the depth of the player 100 based on, for example, a flight time (TOF: Time of Flight) from when the infrared light is irradiated until the reflected light is received.

  FIG. 3 is a diagram for explaining a method of measuring the depth of the player 100 by the infrared sensor 3. As shown in FIG. 3, pulsed infrared light is emitted from the infrared sensor 3 at a predetermined interval. Infrared light emitted from the infrared sensor 3 spreads in a spherical shape with the light emission position of the infrared sensor 3 as a center point.

  For example, the infrared light emitted from the infrared sensor 3 strikes the surface of the player 100 body. Infrared light hitting these surfaces is reflected. The reflected infrared light is detected by the infrared light receiving element of the infrared sensor 3. That is, the infrared sensor 3 detects reflected light whose phase is inverted by 180 degrees with respect to the irradiated infrared ray.

  For example, as shown in FIG. 3, when the player 100 projects both hands forward, the projected hands are closer to the infrared sensor 3 than the body of the player 100. That is, the flight time of the infrared light reflected by both hands of the player 100 is shorter than the flight time of the infrared light reflected by the player's 100 body.

  The value obtained by multiplying the time from when the infrared sensor 3 irradiates the infrared light to the time when the reflected light is detected (that is, the flight time) and the speed of the infrared rays and dividing the result by the half is the measurement reference position and the player 100. Is equivalent to the distance interval (ie, depth). By performing such processing, the infrared sensor 3 measures the depth of the player 100.

  The infrared sensor 3 also detects the contour of the subject (player 100) by detecting the depth difference obtained from the reflected infrared light. As described above, the fact that the infrared sensor 3 receives the reflected light of the infrared light means that an object is arranged at this place. Also, if no other object is placed near the rear of this object, the depth difference between this object and the surroundings of this object will be large. For example, the contour of the player 100 is detected by connecting places where the depth difference is larger than a predetermined value.

  Note that the method of detecting the contour of the player 100 is not limited to the above example. In addition, for example, the contour may be detected based on the luminance of each pixel of the captured image obtained by the CCD camera 2. Also in this case, for example, the contour of the player 100 can be detected by connecting portions having a large luminance difference between pixels.

  Information (depth information) relating to the depth of the player 100 detected as described above is expressed as a depth image, for example. In the present embodiment, an example will be described in which depth information is expressed as a grayscale depth image (for example, 256-bit grayscale image data).

  FIG. 4 is a diagram illustrating an example of a depth image obtained by the infrared sensor 3. As shown in FIG. 4, for example, an object close to the infrared sensor 3 is expressed bright (high brightness), and a distant object is expressed dark (low brightness). The depth of the player 100 corresponds to the brightness (pixel value) of the depth image.

  For example, when the depth image is represented as 256-bit grayscale image data, the brightness of the depth image is different by 1 bit every time the depth of the player 100 is different by 2 centimeters. In this case, the infrared sensor 3 indicates that the depth of the subject can be detected in units of 2 cm. When the player 100 projects both hands forward (FIG. 3), as shown in FIG. 4, the pixels corresponding to both hands of the player 100 are expressed brighter (higher brightness) than the pixels corresponding to the trunk.

  In the present embodiment, the infrared sensor 3 generates a depth image every predetermined time (for example, every 1/60 seconds) as in the CCD camera 2. Based on the captured image obtained by the CCD camera 2 and the depth image obtained by the infrared sensor 3, player position information relating to the position of the part of the player 100 is generated.

  For example, a composite image (RGBD data) is generated by adding the depth information (Depth) indicated by the depth image to the captured image (RGB data) obtained by the CCD camera 2. That is, the composite image includes color information (RGB brightness) and depth information for each pixel.

  When the player position information is generated based on the composite image, first, pixels corresponding to the contour of the player 100 are specified based on the depth image. Next, the color information (RGB brightness) of the pixels surrounded by the outline in the composite image is referred to. Based on the color information of the composite image, pixels corresponding to each part of the body of the player 100 are specified. As this specifying method, for example, a known method such as a pattern matching method for extracting an object (that is, each part of the body of the player 100) from an image by comparison with a comparison image (teacher image) can be applied. is there.

  Based on the pixel values (RGBD values) of the pixels specified as described above, three-dimensional coordinates such as the head and shoulders of the player 100 are calculated. For example, a three-dimensional coordinate is generated by performing a predetermined matrix conversion process on the pixel value. This line example conversion process is executed by, for example, line example calculation similar to the conversion process of two coordinate systems of world coordinates-screen coordinates in 3D graphics. That is, the RGB value indicating the color information of the pixel and the D value indicating the depth are substituted into a predetermined determinant, whereby the three-dimensional coordinates of the pixel are calculated.

  A known method can be applied to the method for calculating the three-dimensional coordinates corresponding to the pixel from the pixel value (RGBD value), and this calculation method is not limited to the above example. In addition, for example, coordinate conversion may be performed using a lookup table.

  FIG. 5 is a diagram illustrating an example of player position information generated by the position detection device 1. As shown in FIG. 5, the player position information includes a plurality of information related to the positions of a plurality of parts of the player 100. The player position information is stored in association with, for example, each part of the player 100 and three-dimensional coordinates.

  FIG. 6 is a diagram illustrating the position of the player 100 specified by the player position information. In the present embodiment, for example, a predetermined position (for example, a measurement reference position) corresponding to the position detection device 1 is set as the origin Op. For example, the origin Op is a three-dimensional coordinate corresponding to the measurement reference position of the infrared sensor 3. Note that the position of the origin Op may be set anywhere in the three-dimensional space where the player 100 is located. For example, a three-dimensional coordinate corresponding to the origin Os of the captured image may be set as the origin Op.

  As shown in FIG. 6, for example, the player position information includes the player's 100 head P1, shoulder P2, upper left arm P3, upper right arm P4, lower left arm P5, lower right arm P6, back P7, left thigh P8, and right. 11 includes 11 three-dimensional coordinates corresponding to P9, left shin P10, and right shin P11.

  Note that the body part of the player 100 indicated by the player position information may be a predetermined part of the player's body (skeleton). For example, this part may be any part of the body that can be specified by the pattern matching method described above.

  For example, player position information generated at predetermined intervals (for example, every 1/60 seconds) is transmitted from the position detection device 1 to the game device 20. The game device 20 receives the player position information from the position detection device 1, acquires the movement of the player (hereinafter, the player's “100” is omitted), and executes the game.

[3. Game executed on game device]
The game apparatus 20 executes a game in which the player performs a game operation in accordance with the music. In this game, for example, a player shown in a captured image acquired from the position detection device 1 is displayed on the game screen.

  FIG. 7 is a diagram illustrating an example of the game screen. As shown in FIG. 7, on the game screen 30, a player image 32 obtained by photographing the player and a plurality of generation position marks 34 arranged around the player image 32 are displayed. Here, since the game is played with the player image 32 displayed on the game screen 30 facing the player, the player image 32 is an image obtained by extracting the contour of the player from the photographed image and performing left-right reversal processing. Become.

  Since the player image 32 is displayed based on the photographed image, when the player moves his / her body, the display of the player image 32 is also updated to match this movement. For example, when the player raises the right hand, the display of the player image 32 is updated so that the right hand is raised as seen from the player in the real space.

  For example, eight generation position marks 34 (generation position marks 34A to 34H) are arranged in a circle so as to surround the player image 32. The display position of the generation position mark 34 corresponds to “generation position” and “target position” according to the present invention. That is, a plurality of generation positions and a plurality of target positions are set on the game screen 30. Here, a plurality of generation positions and a plurality of target positions are set around the reference position (display position of the player image 32).

  A timing guidance mark 36 is displayed near the generation position mark 34. The timing guide mark 36 is generated from the generation position mark 34 when the reference timing approaches. Then, as shown in FIG. 7, the timing guide mark 36 changes the direction to the right after moving upward from the generation position mark 34 over time. The position where the direction is changed corresponds to the “direction changing position” according to the present invention.

  Thereafter, the timing guide mark 36 changes direction downward after moving a predetermined distance in the right direction. Further, the timing guide mark 36 moves downward by a predetermined distance and then turns to the left and returns to the generation position mark 34. When the reference timing comes, the timing guide mark 36 overlaps the generation position mark 34.

  In the present embodiment, the number and timing of the direction change of the timing guide mark 36 are determined according to the beat of the music. For example, in the case of a music with a 4-beat rhythm, as shown in FIG. 7, the direction of the timing guide mark 36 is changed three times. Of the four beat rhythms, the timing guide mark 36 is generated at the timing when the first one beat is hit, and the direction is changed at the timing when the remaining three beats are hit.

  When the player actually moves his / her body so that the player displayed on the player image 32 touches the generation position mark 34 at the timing when the timing guide mark 36 overlaps the generation position mark 34, the player is highly evaluated. It is done. That is, in the present embodiment, the player actually moving his / her body so that the player displayed on the player image 32 touches the generation position mark 34 corresponds to “game operation”.

  As described above, in the game device 20, when the reference timing at which the player should perform the game operation approaches, the timing guide mark 36 is generated from the generation position mark 34, and the direction is changed again according to the beat of the music. It moves so as to return to the generation position mark 34. For example, as compared with the case where the timing guide mark 36 moves in one direction, the movement of the timing guide mark 36 that makes the music beat is easier for the player to feel the rhythm of the music. As a result, the player can easily grasp the reference timing. Hereinafter, this technique will be described in detail.

  The control unit 21 includes, for example, a CPU, a GPU (Graphics Processing Unit), an SPU (Sound Processing Unit), and the like. The control unit 21 executes various processes according to the operating system and other programs.

  The main storage unit 22 includes, for example, a RAM (Random Access Memory). The auxiliary storage unit 23 includes, for example, a hard disk device (information storage medium). The main storage unit 22 stores programs and data read from the auxiliary storage unit 23 or the optical disc (information storage medium). The main storage unit 22 is also used as a work memory that stores data necessary in the course of processing. Further, for example, the main storage unit 22 temporarily stores the player position information received from the position detection device 1 in association with the reception time.

[6. Functions realized with game devices]

As shown in FIG. 10, in the game apparatus 20, a game operation detection unit 50, a game data storage unit 52, a game execution unit 54, an evaluation unit 56, and a guidance unit 58 are realized. These functions are realized by the control unit 21 operating according to a program read from the optical disc.

[6-1. Game operation detection unit]

Here, a case where the game operation detection unit 50 detects w types (w is a natural number) of game operations will be described. For example, the game operation detection unit 50 detects the game operation of the player by determining whether or not the position of each part of the player indicated by the player position information is within a predetermined area range.

  FIG. 11 is an explanatory diagram for explaining a game operation detection method. As shown in FIG. 11, for example, a determination area 60 for determining whether or not a game operation has been performed is set in the three-dimensional coordinate space indicated by the player position information. The three-dimensional coordinate space here is a coordinate system indicating the real space, and is used to indicate the position of each part of the player in the real space. In the present embodiment, the same number of determination areas 60 as the generation position marks 34 (for example, eight) are set. For example, the determination area 60A corresponds to the generation position mark 34A. Similarly, the determination areas 60B to 60H correspond to the generation position marks 34B to 34H.

  For example, the position of the determination area 60 set in the three-dimensional space is determined based on the position of the generation position mark 34. For example, it is determined that the positional relationship between the position of the player indicated by the player position information and the position of the determination area 60 corresponds to the positional relationship between the position of the player image 32 and the position of the generation position mark 34 on the game screen 30. Area 60 is set. For example, when the generation position mark 34 is set around the player image 32 as shown in FIG. 7, the determination area 60 is set around the player's back P7 as shown in FIG.

  The size of the determination area 60 may be set to a predetermined size, or may be determined based on the size of the generation position mark 34, for example. As shown in FIG. 11, for example, the determination region 60 may be a sphere having a predetermined radius.

  By determining whether or not the three-dimensional coordinates of each part of the player indicated by the player position information are within the determination region 60, the game operation by the player is detected. That is, when the three-dimensional coordinates of the part of the player indicated by the player position information are within the determination area 60, it is determined that a game operation has been performed by the player.

  In the present embodiment, eight types of game operations (first game operation to eighth game operation) corresponding to the eight determination areas 60A to 60H are detected. The game operation detection unit 50 determines which type of game operation has been performed by determining in which of the determination regions 60A to 60H the part of the player indicated by the player position information is.

  Information indicating the position and size of the determination area 60 set in the three-dimensional coordinate space is stored in the game data storage unit 52 described later. Further, the player position information acquired from the position detection device 1 is stored in the game data storage unit 52 in chronological order. Further, as a game operation, touching the determination area 60 for a certain period of time may correspond to a “game operation”.

[6-2. Game data storage unit]
The game data storage unit 52 is realized mainly by the main storage unit 22 and the auxiliary storage unit 23. The game data storage unit 52 stores information necessary for executing the game. For example, the game data storage unit 52 stores the following data.
(1) Music data (2) Determination area data indicating the determination area 60 set in the three-dimensional space (3) Data in which player position information is stored in time series (4) Status of game being executed (scores and progress) Game status data indicating time)

  Of the above data, the music data is data prepared in advance by the game creator. The determination area data is data generated when the game is executed. The player position information is data generated by the position detection device 1. The game situation data is data generated and updated by the game program.

  FIG. 12 is a diagram illustrating a data storage example of music data. As shown in FIG. 12, the music data includes original music data, reference timing data, and movement route data.

[Original music data]
The original music data is data obtained by storing general popular music or the like in a predetermined data format. The music indicated by the original music data is a music of n (n is a natural number), and here, a case where a music of 2 beats, 3 beats, or 4 beats is used will be described as an example. In addition, the time signature of a music should just be the time signature used with the normal music, and may be what time signature. In addition to simple time signatures, music such as composite time signatures (for example, 6 time signatures) and variable time signatures (for example, 7 time signatures) may be used.

[Reference timing data]
The reference timing data is data indicating the reference timing at which the player should perform the game operation. The reference timing data is created in consideration of the beat (tempo rhythm) of the music, for example. Here, a case will be described in which the reference timing data indicates the reference timing for performing the game operation for each of w types of game operations (for example, 8 types of game operations).

  FIG. 13 is a diagram illustrating an example of the reference timing data. The t axis shown in FIG. 13 is a time axis. The t-axis indicates the passage of time from the start of music playback. In the present embodiment, the reference timing data indicates the timing at which the player should perform the game operation in units of 1/4 bar. That is, the reference timing data indicates data obtained by dividing one measure into four. In other words, “0” or “1” data indicating whether or not the timing is the reference timing at the start timing of each 1 / n measure in which one measure is divided into n pieces. Is set. The reference timing data is not limited to this, and the reference timing may be indicated in units of 1/256 measures.

  As shown in FIG. 13, whether or not the player should perform a game operation at each time point of 1/4 bar is represented by 8-bit data. That is, for each of the eight types of game operations, whether or not to perform the game operation is determined. In FIG. 13, the bits “A” to “H” indicate whether or not the player should touch the determination areas 60 </ b> A to 60 </ b> H, respectively.

  The bit “A” being “0” indicates that the player should not move his / her body so that the position of the player's part is included in the determination area 60A. On the other hand, the bit “A” being “1” indicates that the player should move his / her body so that the position of the player's part is included in the determination area 60A.

  The same applies to the bits “B” to “H”. That is, the bits “B” to “H” being “0” indicate that the player should not move his / her body so that the positions of the player's parts are included in the determination regions 60B to 60H, respectively. Yes. In addition, the bits “B” to “H” being “1” indicate that the player should move his / her body so that the positions of the player's parts are included in the determination regions 60B to 60H, respectively. ing.

  As described above, the reference timing data is the w-th reference timing data (for example, “A” to “H” data indicating the w-th reference timing at which the w-th game operation (for example, w = 8)) )including. That is, the timing at which at least one of the 8-bit data “A” to “H” is “1” is the reference timing, and at least one of the 8-bit data is “1”. The data can be said to be data indicating the reference timing.

[Movement route data]
The movement route data is data indicating a route along which the timing guide mark 36 moves, and is data indicating a movement route according to the beat of the music indicated by the original music data. The movement route data can be said to be data indicating, for example, the direction change timing at which the timing guide mark 36 should change direction, and the position and direction to change direction. In other words, the movement route data is data defining when and how the timing guidance mark 36 changes direction. A plurality of movement paths are prepared for each beat of the music by the game creator, and information indicating any one of the plurality of movement paths is stored in the movement path data.

  FIG. 14 is a diagram showing a movement route used in the present embodiment. As shown in FIG. 14, one or a plurality of patterns of movement paths are prepared for each beat of music. Data indicating the association in FIG. 14 may be stored in the game data storage unit 52. Information indicating one of the patterns shown in FIG. 14 is stored as the movement route data. For example, in the case of a 4-beat music piece, the movement route of any of patterns A to C shown in FIG. 14 is stored in the movement route data.

  In the example shown in FIG. 14, in “pattern A”, the timing guide mark 36 moves on a square route. In the “pattern B”, the timing guide mark 36 moves on a rhombus route. In the “pattern C”, the timing guide mark 36 moves so as to return to the original position after moving along the path of the letter Z. In “pattern D” associated with a three-beat musical piece, the timing guide mark 36 moves on a triangular path.

  Each pattern includes information indicating the moving speed of the timing guide mark 36 and information indicating the initial moving direction (moving direction immediately after the occurrence) of the timing guide mark 36 in addition to the information indicating the moving path itself. Stored. Also, each pattern shows a direction change timing at which the timing guide mark 36 should change direction, and a position and direction at which the direction change should be made. The pattern associated with the n-beat musical piece shows the movement path so that the timing guidance mark 36 changes direction n-1 times during one measure. It is determined based on the timing at which the beat is beaten. The timing at which the time is struck is the timing at which every 1 / n bar is visited. In other words, each pattern can be said to be information in which information indicating the positional relationship between the generation position of the timing guide mark 36 and the display position is stored in time series.

  The data stored in the game data storage unit 52 is not limited to the above example. The game data storage unit 52 may store various data for executing the game. In addition, for example, image data of the generation position mark 34 and the timing guide mark 36 may be stored. Further, the control unit 21 functions as a means for acquiring various data stored in the game data storage unit 52.

[6-3. Game execution part]
The game execution unit 54 is realized mainly by the control unit 21. The game execution unit 54 executes a game in which the player performs a game operation in accordance with the music (music of n beats). For example, the game execution unit 54 executes the game by updating the game situation data based on an algorithm defined in the game program.

[6-4. Evaluation Department]
The evaluation unit 56 is realized mainly by the control unit 21. The evaluation unit 56 evaluates the game operation by the player based on the operation timing when the game operation is performed by the player and the reference timing indicated by the reference timing data. For example, the evaluation unit 56 evaluates the game operation based on the difference between the reference timing indicated by the reference timing data and the operation timing at which the player actually performed the game operation. For example, the smaller the time difference between the reference timing and the operation timing, the higher the evaluation of the game operation.

  In the case of the present embodiment, for example, the timing (reference timing) when the timing guidance mark 36 starting from the generation position mark 34 returns to the generation position mark 34 and the player's part indicated by the player position information are actually within the determination area 60. "MARVELOUS", "PERFECT", "GREAT", "GOOD", "ALMOST", or "BOO" is determined as an evaluation based on the time of entering (operation timing) and the deviation time .

  FIG. 15 is a diagram showing the relationship between the deviation time (ΔT) and the evaluation. Data indicating this relationship may be stored in the game data storage unit 52, for example. For example, the deviation time (ΔT) takes a negative value when the operation timing is earlier than the reference timing. On the other hand, for example, the deviation time (ΔT) takes a positive value when the operation timing is delayed from the reference timing. For example, an evaluation associated with the deviation time is given to the player.

  As shown in FIG. 15, any one of “MARVELOUS”, “PERFECT”, “GREAT”, “GOOD”, “ALMOST”, and “BOO” is given in ascending order of the deviation time (ΔT). . If these evaluations are arranged in order from the highest, they are “MARVELOUS”, “PERFECT”, “GREAT”, “GOOD”, “ALMOST”, and “BOO”. That is, “MARVELOUS” having the smallest deviation time (ΔT) is the highest evaluation, and “BOO” having the largest deviation time (ΔT) is the lowest evaluation.

[6-5. Guide section]
The guide unit 58 is mainly realized by the control unit 21 and the display unit 27. Based on the reference timing data, the guide unit 58 moves the guide image (for example, the timing guide mark 36) from the generation position to the target position while changing the direction according to the beat of the music on the game screen 30. To guide the reference timing to the player. The guide unit 58 moves the timing guide mark 36 based on the movement route data. The timing guide mark 36 is generated from the position where the game screen 30 is generated, and moves toward the target position on the game screen 30 while changing the direction at the direction change timing corresponding to the beat of the music.

  The generation position is a position where the timing guide mark 36 appears when the reference timing approaches, for example, the display position of the generation position mark 34. The target position is a position (a destination point) to which the timing guide mark 36 is moved, and is a position where the timing guide mark 36 should be displayed when the reference timing arrives.

  The generation position and the target position may be the same or different. In the present embodiment, the timing guide mark 36 is generated from the generation position mark 34 and returns to the generation position mark 34. Therefore, the display position of the generation position mark 34 is both “generation position” and “target position”. .

  In the embodiment, since the generation position and the target position are the same, an image (generation position mark 34) is displayed at the generation position and the target position, but the image for guiding the target position to the user is The image may be displayed at the target position, and the image may not be displayed at the generation position. Here, the reason why the image is displayed at the target position is to allow the user to grasp the position of the guide image when the reference timing arrives. That is, the user grasps the reference timing based on the positional relationship between the image displayed at the target position and the guide image. In addition, when the generation position and the target position are different, an image may be displayed only at the target position and no image may be displayed at the generation position.

  The direction change timing is a timing determined based on the beat of the music. Here, if the “beat” indicates each section obtained by dividing one measure into n, the direction change timing is the start timing of the section. Further, if the “beat” indicates a break position obtained by dividing one measure into n pieces, the direction change timing is the timing of the break position.

  When the reference timing is included in a predetermined period after the present time (for example, a period from the current time to one bar later, hereinafter referred to as a guidance target period), the guide unit 58 performs a timing at the occurrence position mark 34 on the game screen 30. The guide mark 36 is generated and moved back to the generation position mark 34 while changing the direction according to the beat of the music according to the time difference between the present time and the reference timing.

  FIG. 16 is an explanatory diagram for explaining a method of moving the timing guide mark 36. Here, a case where the timing at which “B” of the reference timing data shown in FIG. 13 is “1” is approaching will be described. That is, a case where the timing guide mark 36B is generated from the generation position mark 34B and moves while changing its direction will be described as an example. Furthermore, the case where a 4-beat music is used is demonstrated here.

As shown in FIG. 16, the display position of the generation position mark 34B is set as the generation position Q. In addition, direction change positions R ₁ , R ₂ , R ₃ that satisfy a predetermined positional relationship with the generation position Q are set on the game screen 30. The direction change positions R ₁ , R ₂ and R ₃ are positions where the timing guide mark 36B changes direction.

Here, toward the display position S of the player image 32 to generate a position Q, the direction change position R ₂ was apart from the generation position Q by a predetermined distance L position. And among the vertices of a square having a line segment connecting the generation position Q and the direction change position R ₂ as a diagonal line (one side indicated by a broken line is a square having a distance D), points other than the generation position Q and the direction change position R ₂ are selected. , And direction change positions R ₁ and R ₃ . The timing guide mark 36B moves on each side of the square. That is, the movement route data includes information indicating each vertex of the square and information in which the position (position on each side of the square) where the timing guide mark 36B is to be displayed is stored in time series. It is.

More specifically, for example, the timing guide mark 36B is generated at the generation position Q when the timing one bar before the reference timing in which “B” of the reference timing data shown in FIG. As the distance d between the display position T and the generation position Q of the timing indicator mark 36B is increased gradually, the timing indicator mark 36B is moved toward the direction change position R ₁ from the generation position Q. Furthermore, the reference timing data "B" is 3/4 bars before the timing of the reference timing is "1" visits, the timing indicator mark 36B reaches the direction change position R _1.

When the timing indicator mark 36B reaches the direction change position R _1, the moving direction is changed by 90 ° clockwise. The distance between the display position T and direction change position R ₁ in the timing indicator mark 36B is so increased gradually, the timing indicator mark 36B moves toward the direction change position R ₁ in the direction change position R _2. Furthermore, the reference timing data "B" is 2/4 bars before the timing of the reference timing is "1" visits, the timing indicator mark 36B reaches the direction change position R _2.

Similarly thereafter, the moving direction of the timing indicator mark 36B is changed by 90 ° clockwise to move toward the direction change position R ₂ in the direction change position R _3. When the reference timing data "B" is the timing of 1/4 bars before the reference timing is "1" visits, the timing indicator mark 36B reaches the direction change position R _3. Then, the movement direction of the timing indicator mark 36B is changed by 90 ° clockwise to move toward the generation position Q from the direction change position R _3. When a reference timing whose reference timing data “B” is “1” arrives, the timing guide mark 36B overlaps the generation position mark 34B.

Thus, when the time point “1” of the reference timing data “B” approaches, the timing guide mark 36B is generated, and the generation position Q → the direction change position R ₁ → the direction change position R ₂ → the direction change position. It moves while changing direction in the order of R ₃ → generation position Q. It should be noted that the moving speed of the timing guide mark 36B may be constant or may change during the movement.

  In the above, the manner in which the timing guide mark 36B moves has been described, but the same applies to the movement of the other timing guide marks 36A, 36C to 36H. The above description of “B” can be read as “A” or “C” to “H”.

  FIG. 17 is a diagram for explaining the movement of the timing guide mark 36 in time series. For example, while a music piece is being played, data for a guidance target period (for example, a period from the current time to one bar later) is read from the reference timing data. Based on the read data, a timing guidance mark 36 for guiding the reference timing within the guidance target period is displayed on the game screen 30.

  As shown in FIG. 17, when the current time is time t1, the data of “B” at time t5 is “1” within the guidance target period (time t1 to t5). A timing guide mark 36B is generated on the mark 34B.

  When the current time is time t2, since the data of “E” at time t6 is “1” within the guidance target period (time t2 to t6), the timing guidance mark 36E is added to the generation position mark 34E. Occur. Further, the timing guide mark 36B generated at time t1 reaches the direction change position and changes direction.

  When the current time is time t3, there is no data that is newly “1” within the guidance target period (time t3 to t7), so the timing guidance mark 36 is not newly generated. The timing guide mark 36B and the timing guide mark 36E reach the respective direction change positions and change directions.

  When the current time is time t4, since the data of “H” at time t8 is “1” within the guidance target period (time t4 to t8), the timing guidance mark 36H is added to the generation position mark 34H. Occur. The timing guide mark 36B and the timing guide mark 36E reach the respective direction change positions and change directions.

  When the current time is time t5, there is no data that is newly “1” within the guidance target period (time t5 to t9), so the timing guidance mark 36 is not newly generated. Further, since the data of “B” at time t5 is “1” and the reference timing at which the player should touch the determination area 60B has arrived, the timing guide mark 36B reaches the generation position mark 34B. In addition, before this, when the player performs a game operation and the evaluation is performed, the timing guide mark 36B may be deleted. Further, the timing guide mark 36E and the timing guide mark 36H reach the respective direction change positions and change directions.

  Similar display control is performed at subsequent times. Thus, when the reference timing approaches, the timing guide mark 36 moves while changing its direction according to the beat from the generation position, so that the player can easily feel the rhythm of the music.

  In the above description, the case has been described in which the turn timing comes after k / n measures (k: natural number) before the reference timing after the timing guide mark 36 is generated at the generation position a predetermined time before the reference timing. What is necessary is just to make it change the direction of the timing guidance mark 36 at the timing at which the beat of a music is beaten. In other words, the direction change timing corresponding to the beat of the music may be set in the movement route data.

  For example, it is assumed that the guidance target period is m bars, and the reference timing comes at time t of a music piece of n beats (where t is a multiple of 1 / n bars). For example, after the timing guide mark 36 is generated at the timing before the m-th measure or at the timing before the relevant timing, the first direction change is made before the “m−1 / n” measure at the time t, and thereafter the k at the time t. A change of direction may be made each time a change of turn timing comes before / n bars (k: k <m * n-1).

  For example, if m = 1 bar, n = 3 time signature, t = 20th bar, the timing guide mark 36 is generated when the current time is the 19th bar, and the “19 + 1/3” bar, “19 + 2 / After the direction change timing arrives at the 3rd bar, the reference timing comes at the 20th bar.

  Further, the case where the direction change is performed by rotating the timing guide mark 36 by 90 ° clockwise when the direction change timing has come has been described. However, the direction of movement of the timing guide mark 36 before and after the direction change is described. Need only change by a predetermined angle, and the method of changing the moving direction is not limited to this. In addition, for example, the moving direction may be rotated counterclockwise.

  In addition, the timing guidance mark 36 is generated at the generation position when the guidance target period has been visited and the movement is started immediately after that. However, after the timing guidance mark 36 is generated at the generation position, the system waits for a predetermined time. After that, the movement may be started. For example, the timing guide mark 36 may be generated three bars before the reference timing, and the start of movement may be waited for one bar.

[7. Processing executed in game device]
FIG. 18 is a flowchart showing an example of processing executed in the game apparatus 20. The processing in FIG. 18 is executed by the control unit 21 operating according to a program read from the optical disc.

  As shown in FIG. 18, first, the control unit 21 starts playing a music piece (S101). The control unit 21 constructs a three-dimensional space in the main storage unit 22 and sets the determination area 60 (S102). The control unit 21 sets a plurality of generation positions on the game screen 30 and causes the generation position marks 34 to be displayed on the game screen 30 (S103).

  In S102, for example, the determination area 60 is set so as to satisfy a predetermined positional relationship with the back P7 of the player indicated by the player position information acquired from the position detection device 1. In S103, a plurality of generation position marks 34 are displayed around the player image 32. That is, the positional relationship between the player image 32 and the generation position mark 34 corresponds to the positional relationship between the player's back P7 and the determination area 60.

  The control unit 21 refers to the reference timing data and the movement route data, and performs display control processing for the timing guide mark 36 on the game screen 30 (S104).

  FIG. 19 is a flowchart showing an example of the display control process executed in S104. The process shown in FIG. 19 is performed based on the reference timing indicated by each of “A” to “H” of the reference timing data. That is, the display control process described below is executed for each of the timing guide marks 36A to 36H for guiding the reference timing associated with each of the generation position marks 34A to 34H. Here, the case where the display control process of the timing guidance mark 36A is performed based on the data “A” of the reference timing data will be described.

  First, as shown in FIG. 19, the control unit 21 displays the player image 32 on the game screen 30 based on the captured image acquired from the position detection device 1 (S201).

  The control unit 21 refers to the reference timing data and determines whether or not the reference timing is included in the guidance target period (S202). For example, it is determined whether or not “A” of the reference timing data is “1” in the period from the current time to one measure later.

  When it is not determined that the reference timing is included in the guidance target period (S202; N), this process ends, and the process proceeds to S105.

  When it is determined that the reference timing is included in the guidance target period (S202; Y), the control unit 21 calculates a time interval U between the current time and the reference timing within the guidance target period (S203). That is, the time interval U between the time when the reference timing data “A” is “1” and the current time is calculated within the guidance target period.

  The control unit 21 determines whether or not the time interval U calculated in S203 is one measure (S204). That is, it is determined whether or not the time interval U is the same as the length of the guidance target period.

  When it is determined that the time interval U is one measure (S204; Y), the control unit 21 generates the timing guide mark 36A at the position of the generation position mark 34A (S205). That is, since the reference timing “A” is newly included in the guidance target period, the timing guidance mark 36A is generated at the position of the generation position mark 34A.

  When it is not determined that the time interval U is one measure (S204; N), the control unit 21 refers to the movement route data, and based on the time interval U, has the turning timing determined according to the beat of the music come? It is determined whether or not (S206). The direction change timing is defined in the movement path data, and here, when the time interval U is k / n bars (here, 1/4 bar, 2/4 bar, or 3/4 bar). It is determined that the direction change timing has arrived.

  When it is determined that the direction change timing has arrived (S206; Y), the control unit 21 changes the direction of movement of the timing guide mark 36A according to the movement route indicated by the movement route data (S207). Here, the movement route data is shown so that the movement direction of the timing guide mark 36A is rotated 90 ° clockwise.

  When it is not determined that the direction change timing has come (S206; N), the control unit 21 determines the display position of the timing guidance mark 36A based on the current moving direction according to the moving route indicated by the moving route data (S208). For example, the display position of the timing guide mark 36A is determined so that the distance from the direction change position increases as the time interval U decreases.

  In the above description, the display control of the timing guide mark 36A has been described. However, the display control similar to the above is performed for the timing guide marks 36B to 36H based on the data “B” to “H” of the reference timing data. Is called. That is, “A” in the above description can be read as any of “B” to “H”.

  Returning to FIG. 18, when display control of the timing guidance mark 36 is performed in S104, the control unit 21 performs a game operation evaluation process (S105).

  FIG. 20 is a flowchart illustrating an example of the game operation evaluation process. The process shown in FIG. 20 is executed for eight game operations corresponding to the determination areas 60A to 60H. Here, a case will be described in which a game operation in which the player touches the determination area 60A is evaluated. The game operation evaluation process in which the player touches the other determination areas 60B to 60H is performed by replacing the following “A” with “B” to “H”.

  As shown in FIG. 20, first, the control unit 21 determines whether or not the current time is within the determination period (S301).

  FIG. 21 is a diagram for explaining the determination period. In FIG. 21, the t axis indicates a time axis. “X” indicates the timing at which the determination area 60A should be touched. That is, “X” indicates the reference timing corresponding to the determination area 60A, and is the time when “A” of the reference timing data is “1”. “Y1” and “Y2” indicate the timing at which the determination area 60A is touched. That is, “Y1” and “Y2” indicate the operation timing.

  For example, a determination period is set for each reference timing. In FIG. 19, “Z” indicates a determination period. The determination period (Z) is a period including a reference timing (X), a period from the reference timing (X) to a predetermined time before, and a period from the reference timing (X) to a predetermined time later. The determination period (Z) in FIG. 21 is a fixed period centered on the reference timing (X).

  In the determination period (Z), the first operation timing within this period is handled as an evaluation target. For example, in the example shown in FIG. 21, there are two operation timings (Y1, Y2) in the determination period (Z). In this case, the first operation timing (Y1) is to be compared with the reference timing (X). The second and subsequent operation timings (Y2) are excluded from the comparison target with the reference timing (X). The reason for doing this is to allow the evaluation to be performed appropriately even when the player repeatedly touches the determination area 60A many times around the reference timing (X).

  Returning to FIG. 20, when it is determined that the current time is not within the determination period (S <b> 301; N), the control unit 21 ends this process. That is, the control part 21 performs the process of S106 of FIG.

  On the other hand, when it is determined that the current time is within the determination period (S301; Y), the control unit 21 determines whether or not the operated flag is “0” (S302). The operated flag is information that is stored in the main storage unit 22 or the like and indicates whether or not the determination area 60A has been touched in the current determination period. The manipulated flag takes a value of 0 or 1. “0” indicates that the determination area 60A is not touched. On the other hand, “1” indicates that the determination area 60A has been touched.

  When it is not determined that the operated flag is “0” (S302; N), the process proceeds to S309.

  On the other hand, when it is determined that the operated flag is “0” (S302; Y), the control unit 21 determines whether or not the determination area 60A has been touched (S303). This determination is performed by determining whether or not the three-dimensional coordinates of each part of the player indicated by the player position information are within the determination area 60A.

  If it is not determined that the determination area 60A has been touched (S303; N), the process proceeds to S309. On the other hand, when it is determined that the determination area 60A has been touched, the control unit 21 updates the operated flag to “1” (S304).

  Further, the control unit 21 acquires a time difference (ΔT) between the reference timing and the operation timing (S305). This deviation time (ΔT) takes a negative value when the operation timing is earlier than the reference timing. On the other hand, the deviation time (ΔT) takes a positive value when the operation timing is delayed from the reference timing. The operation timing may be a timing when it is determined that the determination area 60A is touched in S303, or may be a time when the process of S305 is executed.

  The control unit 21 determines the evaluation based on the deviation time (ΔT) acquired in S305 (S306). For example, the evaluation is determined based on the data shown in FIG. The control unit 21 performs a game process based on the evaluation determined in S306 (S307), and erases the timing guide mark 36 (S308). The game process performed here is a display effect process for the game screen 30 or a process for increasing or decreasing the score indicated by the game situation data.

  The control unit 21 determines whether the end timing of the determination period has arrived (S309). If it is not determined that the end timing of the determination period has arrived (S309; N), the process proceeds to S106.

  On the other hand, when it is determined that the end timing of the determination period has arrived (S309; Y), the control unit 21 determines whether or not the operated flag is “0” (S310). The case where the operated flag is “0” is a case where the determination area 60A is not touched within the determination period.

  When it is determined that the operated flag is “0” (S310; Y), the control unit 21 determines the lowest evaluation (S311) and deletes the timing guide mark 36A (S312). In this case, for example, the score decreases by a predetermined value. Then, the process proceeds to S106.

  On the other hand, when it is not determined that the operated flag is “0” (S310; N), the control unit 21 updates the operated flag to “0” (S313). Then, the process proceeds to S106.

  Returning to FIG. 18, the control unit 21 determines whether or not the score is within a predetermined range (S106). When it is determined that the score is within the predetermined range (S106; Y), the control unit 21 displays a game over screen (S107) and ends this process.

  On the other hand, when it is not determined that the score is within the predetermined range (S106; N), the control unit 21 determines whether or not the reproduction of the music has ended (S108). If it is not determined that the music has been played back (S108; N), the process returns to S104. On the other hand, when it is determined that the reproduction of the music has ended (S108; Y), the control unit 21 displays a game result screen (S109), and ends the present process.

  In the game apparatus 20 described above, when the reference timing at which the player should perform the game operation approaches, a timing guide mark 36 is generated at the generation position mark 34, and the timing guide mark 36 changes direction according to the beat of the music. While moving, the game screen 30 is moved. Since the timing guide mark 36 changes direction so as to cut the beat of the music, the player can easily perceive the rhythm of the music, so that the reference timing can be easily grasped. For example, even if the music is difficult to hear due to noise around the player, the rhythm of the music can be easily felt from the movement of the timing guide mark 36.

  Further, in particular, after the timing guide mark 36 is generated at the generation position at the timing before the m-th measure (m: natural number) of the reference timing or the timing before the timing, the generated timing guide mark 36 is moved to the initial position. The first direction change is made before the “m−1 / n” measure of the reference timing, and thereafter, the timing guide mark 36 is changed every time the timing before the k / n measure of the reference timing comes. However, by moving to the target position, the number of beats struck during one measure corresponds to the number of times the direction of the timing guide mark 36 changes during that time, so that the player can feel the rhythm of the music more easily. Become.

[7. Modified example]
The present invention is not limited to the embodiments and modifications described above, and can be appropriately changed without departing from the spirit of the present invention.

  (1) For example, when a large number of timing guidance marks 36 are displayed on the game screen 30, it is difficult for the player to grasp where these timing guidance marks 36 are generated and where they are heading. It may become. Therefore, when the timing guide mark 36 is generated, the color or size of the generated position mark 34 is changed to make it easier for the player to know where the timing guide mark 36 is generated and where it returns. May be.

  When the guidance unit 58 of the present modification displays a given image (for example, the generation position mark 34) at the generation position or the target position on the game screen 30, and a guidance image (for example, the timing guide mark 36) is generated. Or, when a guide image changes direction, a given image is changed.

  The case where the timing guidance mark 36 is generated is, for example, a case where the reference timing is included in the guidance target period. The case where the timing guide mark 36 changes direction is the case where the timing guide mark 36 reaches the direction change position and the case where the direction change timing arrives.

  “Change the generation position mark 34” means to change the display form of the generation position mark 34. For example, the image data itself of the generation position mark 34 is changed to another image data, and the shape of the generation position mark 34 is changed. , Changing the size, color, or brightness, and blinking the generation position mark 34.

  FIG. 22 is a diagram showing a game screen 30 displayed in the modification (1). As shown in FIG. 22, when the reference timing is not included in the guidance target period, the timing guidance mark 36 is not displayed on the game screen 30, and therefore the occurrence position mark 34 does not change. For example, when the reference timing is included in the guidance target period, that is, when the timing guidance mark 36 is generated and starts moving, the generation position mark 34 changes.

  In the example shown in FIG. 22, “B” of the reference timing data in the guidance target period is “1”, and the timing guidance mark 36B is generated from the generation position mark 34B. Then, the generation position mark 34B changes from a round image to a star image. When the timing guide mark 36B returns to the generation position mark 34B while repeating the direction change (that is, when the reference timing comes), the generation position mark 34 returns. That is, the generation position mark 34B returns from the star-shaped image to the round image.

  In FIG. 20, the case where the generation position mark 34 changes when the timing guide mark 36 is generated has been described. However, as described above, the generation position mark 34 changes when the direction of the timing guide mark 36 is changed. You may do it. For example, when there are three turning positions (three turning timings) in a music of four beats, when the timing guide mark 36 reaches any turning position (when any turning timing comes) ), The generation position mark 34 may be changed.

  According to the modified example (1), when the generation position mark 34 changes, the player can easily grasp where the timing guide mark 36 is generated and where it is heading. As a result, the player can easily grasp which determination area 60 should be touched.

  (2) Further, for example, when a plurality of timing guidance marks 36 are displayed on the game screen 30, it is difficult to grasp whether the timing guidance mark 36 has just been generated or has already changed direction. There is. Therefore, the timing guide mark 36 may be changed when the direction is changed.

  The guide unit 58 of the modified example (2) changes the guide image when the guide image (for example, the timing guide mark 36) changes direction. The timing information mark 36 changes before and after the timing information mark 36 changes direction.

  “Change timing information mark 36” means to change the display form of the timing information mark 36 as in the case of the occurrence position mark 34. For example, the image data itself of the timing information mark 36 is changed to another image data. At least one of changing the shape, size, color, and luminance of the timing information mark 36 and blinking the timing information mark 36.

  For example, it is determined whether or not the direction change timing has arrived. Before the direction change timing has arrived, the timing guide mark 36 takes the first display form (for example, a round shape), and the direction change timing has arrived. The timing guide mark 36 takes a second display form (for example, a star shape) different from the first display form.

  FIG. 23 is a diagram showing a game screen 30 displayed in the modification (2). As shown in FIG. 23, for example, the timing guide mark 36 becomes a round image until the timing guide mark 36 reaches the third turnaround timing. When the timing guide mark 36 reaches the third direction change timing, the timing guide mark 36 changes to become a star-shaped image and moves toward the generation position mark 34B.

  According to the modification (2), the timing guide mark 36 changes before and after the direction change, so that the player can easily grasp whether or not the timing guide mark 36 has changed direction. As a result, the player can easily grasp the reference timing.

  In addition, in FIG. 23, the case where the timing guidance mark 36 changes when the third direction change timing arrives has been described, but when the first or second direction change timing arrives, the timing guide mark 36 changes. Alternatively, the timing information mark 36 may be changed every time the direction change timing is reached.

  (3) Further, for example, an image other than the timing information mark 36 may move on the moving route of the timing information mark 36.

  FIG. 24 is a diagram illustrating an example of the game screen 30 of the modification (3). As shown in FIG. 24, for example, the interference mark 38B is displayed on the route of the timing guide mark 36B. The obstruction mark 38B does not guide the reference timing, and does not move based on the interval between the current time and the reference timing. For example, the interference mark 38B is generated from the generation position mark 34B, and then proceeds straight without being changed in direction, and is erased from the game screen 30.

  In the game device 20 of the modification (3), the dummy guide image (for example, the interference mark 38B) is displayed on the game screen 30 along the same route as the guide image (for example, the timing guide mark 36B) from the generation position. And a means for moving the dummy guide image without changing the direction at the direction change position after moving to any direction change position where the direction changes. The means is realized by the game execution unit 54, for example.

  Even if the obstruction mark 38B reaches the direction change position, it moves without changing direction. That is, as shown in FIG. 22, the game screen 30 may be erased from the game screen 30 while maintaining the moving direction. For example, data indicating the movement path of the interference mark 38B is stored in advance in the game data storage unit 52, and the interference mark 38B moves based on the data.

  In the example of the screen shown in FIG. 24, the case has been described in which the obstruction mark 38 </ b> B moves without changing the direction at the first one of the three turning positions, but the first turning position. Then, the direction may be changed so that the direction is not changed at the second direction change position. Further, the direction may be changed at the second direction change position, and the direction change may not be made at the third direction change position.

  Further, the interference mark 38B may have the same shape as the timing guide mark 36B or may have a different shape. For example, the interference mark 38B may be an image having the same shape as the timing guide mark 36B but only a different color. Further, the interference mark 38B may be moved at the same speed as the timing guide mark 36B, or may be moved at a different speed, for example.

  According to the modified example (3), the interest of the game can be improved by displaying the interference mark 38 on the game screen 30.

  (4) Further, for example, in the modification (3), the case has been described in which the disturbing mark 38 is moved to confuse the player and improve the interest of the game. May be moved while changing direction according to different beats.

  For example, in the case of the embodiment, the timing guide mark 36 moves while changing its direction on any of the movement paths of the patterns A to C according to the music of 4 beats. You may make it move, changing direction in the movement path | route of the pattern D according to the music of 3 beats. Since some timing information marks 36 move so as to engrave a three-beat rhythm, the player feels a three-beat rhythm from the movement of the timing information marks 36, but in reality, the music is a four-beat tune. Since the game operation is performed together, the interest of the game can be improved.

  FIG. 25 is a diagram illustrating an example of the game screen 30 of the modification (4). As shown in FIG. 25, for example, the timing guidance mark 36 for guiding a part of the reference timing moves while changing the direction according to the music of 3 beats. The direction change according to the music of 3 beats means, for example, that two direction change timings come within the guidance target period.

  For example, as shown in FIG. 25, after the timing guide mark 36B is generated from the generation position mark 34B and moved in a predetermined direction, the timing guide mark 36B proceeds in the moving direction rotated 120 ° clockwise from the original moving direction. Thereafter, the moving direction is further rotated clockwise by 120 ° from this moving direction and returned to the generation position mark 34B. That is, each side of the triangle having the occurrence position mark 34B as a vertex is a movement path of the timing guide mark 36B.

  On the other hand, the other normal timing guide marks 36 move on the sides of the square while changing direction according to the music of 4 beats as in the embodiment, so that the player is confused by the rhythm of the disturbing mark 38B. The game will be played without being played.

  The guide unit 58 of the modified example (4) is based on the reference timing data, the first guide means for moving the timing guide mark 36 while changing the direction according to the beat of the music, and the timing guide mark 36 as the beat of the music. Includes second guiding means that moves while changing direction according to different beats. For example, among the reference timings indicated by the reference timing data, the timing guide marks 36 for guiding some reference timings are moved along a movement path associated with a beat different from the beat of the music.

  This part of the reference timing may be determined in advance or may be determined dynamically. Dynamically determined is a timing determined according to the progress of the game. The guide unit 58 may include switching means for switching means for guiding the reference timing to the player between the first guide means and the second guide means based on the game results of the player. For example, when the score indicated by the game situation data is within a predetermined range (for example, a reference value or more), the timing guide mark 36 may be moved along a movement route corresponding to a beat different from the beat of the music.

  The guide unit 58 reads information indicating a movement route associated with a beat different from the beat of the music among the movement routes stored in the game data storage unit 52, and moves the timing guide mark 36 based on the information. . For example, when the timing guide mark 36 is moved based on the pattern A associated with the 4-beat music, the timing guide mark 36 is moved based on the pattern D associated with the 3-beat music.

  According to the modified example (4), for example, even when the user plays with a piece of music of four beats, the timing guide mark 36 for guiding a part of the reference timing is moved so as to cut in three beats. From the movement of some timing guide marks 36, a time signature different from the time signature of the music is felt, so that the interest of the game can be improved.

  (5) Further, for example, the moving distance and moving speed of the timing guide mark 36 for guiding the subsequent reference timing may be changed according to the operation amount of the game operation. Here, at the timing when the timing guide mark 36 overlaps the generation position mark 34, the player moves his / her body so that the generation position mark 34 is hit, and the game operation is performed. The moving distance and moving speed of the timing guide mark 36 for guiding the next reference timing may be changed according to the speed of the part at the time of performing the tapping operation.

  The game operation detection unit 50 of the modification (5) includes means for detecting the operation amount of the game operation. Here, the change amount of the part of the player corresponds to the “operation amount”.

  The guide unit 58 includes means for determining the moving distance of the guide image based on the operation amount of the game operation when the game operation is evaluated. When the game operation is evaluated, the guide unit 58 determines from the moving distance and moving speed from the generation position of the guide image (for example, the timing guide mark 36) to the first direction change position, and the direction change position of the guide image. At least one of the moving distance and moving speed to the next turning position and the moving distance and moving speed from the last turning position to the target position in the guide image is changed based on the operation amount of the game operation Means to do.

  FIG. 26 is a diagram illustrating an association between the change amount of the player position information and the moving distance and moving speed of the timing guide mark 36. Data indicating the association is stored in the game data storage unit 52, for example. As shown in FIG. 26, for example, the change amount (or speed) of each part of the player indicated by the player position information is associated with information indicating the moving distance and moving speed of the timing guide mark 36.

  As the amount of change of each part of the player indicated by the player position information, information indicating the position change amount of any part of the player in a predetermined period is stored, that is, information regarding the speed of the part of the player is stored. . Here, a case where three types of “small”, “normal”, and “large” corresponding to the amount of change in the player position information are stored will be described. For example, by comparing the amount of change in the part of the player with a threshold value, it is determined which of the above-mentioned changes in the position of the part of the player belongs.

  The change amount on the player position is “large” when the position change of the player's part in the predetermined period is larger than the first threshold. For example, the player moves his hand quickly and hits the generated position mark 34. This is when the operation is performed. On the other hand, the change amount on the player position is “small” when the position change of the player's part in the predetermined period is smaller than the second threshold value (<first threshold value). This is a case where an operation of hitting the generation position mark 34 is performed. The change amount on the player position is “ordinary” when the position change of the player's part in a predetermined period is between the first threshold value and the second threshold value. This is a case where an operation of hitting the mark 34 is performed.

  As the information indicating the movement distance of the timing guide mark 36, information indicating how far and in what direction the direction change position is set as viewed from the generation position is stored. Here, “close”, Three types of “normal” and “far” are stored. In addition, as information indicating the moving speed of the timing guide mark 36, information indicating the moving speed after being generated from the generation position is stored. Here, three types of "slow", "normal", and "fast" are stored. The case where it will be described. For example, information on the distances D and L between the generation position and the direction change position and information on the moving speed at which the timing guide mark 36 is moving are stored.

  When the game operation is evaluated, the guide unit 58 refers to the time-series change in the player position information stored in the game data storage unit 52 and specifies the amount of change in the part corresponding to the game operation. . Then, the guide unit 58 moves the timing guide mark 36 based on the moving distance and moving speed associated with the specified change amount.

  FIG. 27 is a diagram illustrating a moving path of the timing guide mark 36 when the moving distance and the moving speed change according to the change of the player position information. Here, a case will be described as an example where the player performs a game operation to touch the determination area 60B with the right hand when the reference timing whose reference timing data “B” is “1” comes. First, the change amount of the player's lower right arm P6 is acquired based on the time-series change of the three-dimensional coordinates of the player's lower right arm P6 when the player touches the determination area 60B.

When the amount of change of the player's lower right arm P6 is “small”, as shown in FIG. 27, the direction change position R is shifted to a position away from the generation position Q (display position of the generation position mark 34B) by a distance L / 2. _N2 is set. Then, the timing guide mark 36 moves along each side of a square whose diagonal line is a line connecting the generation position Q and the direction change position _RN2 . In this case, the timing guide mark 36 moves in the order of the generation position Q → the direction change position R _N1 → the direction change position R _N2 → the direction change position R _N3 → the generation position Q, and the movement distance becomes 2D.

If the amount of change in the lower right arm P6 of the player is "normal", as in the embodiment, the timing indicator mark each side of the square to the line connecting the generation position Q and direction change position R ₂ and diagonals 36 moves. In this case, the timing guide mark 36 moves in the order of the generation position Q → the direction change position R ₁ → the direction change position R ₂ → the direction change position R ₃ → the generation position Q, and the movement distance becomes 4D.

When the amount of change of the player's lower right arm P6 is “large”, as shown in FIG. 27, the direction change position R _F2 is at a position 2L away from the generation position Q (the display position of the generation position mark 34B). Is set. Then, the timing guide mark 36 moves along each side of a square whose diagonal is a line segment connecting the generation position Q and the direction change position _RF2 . In this case, the timing guide mark 36 moves in the order of the generation position Q → the direction change position R _F1 → the direction change position R _F2 → the direction change position R _F3 → the generation position Q, and the movement distance becomes 8D.

  Then, the timing guidance mark 36B for guiding the reference timing to be visited thereafter moves while changing the direction at the direction changing position set as described above. Since the direction change timing does not change, the moving speed of the timing guide mark 36B increases as the moving distance increases. The moving distance and moving speed are determined again according to the game operation performed at the reference timing guided by the timing guide mark 36B.

  According to the modified example (5), the moving distance and moving speed of the timing guide mark 36 for guiding the next reference timing can be changed according to the position change of the player's part at the reference timing. Can be improved.

  In the embodiment described so far, the case where the game operation is detected based on the player position information has been described. However, the “game operation” means that each button provided on the controller of the operation unit 26 is pressed. You may make it correspond to. In this case, the direction changing position may be determined according to the strength with which the player presses the button of the operation unit 26. For example, as the player strongly presses the operation unit 26, the moving distance of the timing guide mark 36 may be increased and the moving speed may be increased.

  In this case, the game operation detection unit 50 is based on a detection signal from an operation means (for example, the operation unit 26) including an operation detection unit that detects an operation of the player and a pressure detection unit that detects a pressure applied to the detection unit. The player's game operation is detected. For example, the button of the operation unit 26 corresponds to the operation detection unit. For example, the operation unit 26 includes a button that can be pushed by the player. The game operation detection unit 50 detects whether or not a game operation has been performed by acquiring a detection signal from the button from the operation unit 26.

  Further, for example, the operation unit 26 includes a pressure sensor that detects the pressure of pressing the button. The pressure sensor corresponds to a pressure detection unit. The game operation detection unit 50 detects the pressure applied to the button by acquiring a detection signal from the pressure sensor from the operation unit 26.

  Also in this case, the movement distance and movement speed of the timing guide mark 36 can be changed by storing the association between the pressure on the button of the operation unit 26 and the movement distance and movement speed of the timing guide mark 36. Since it is possible, the interest of the game can be improved.

  Further, touching the touch panel of the operation unit 26 may correspond to “game operation”. In this case, the operation unit 26 includes a pressure-sensitive sensor that detects pressure at the time of touch inside the touch panel. The moving distance of the timing guide mark 36 may be changed according to the pressure when the player touches the touch panel. In addition, for example, the pressure may be detected based on the contact area of the touch panel.

  Further, the “operation amount” of the game operation is not limited to the speed and pressure of the part described above. In addition, for example, the number of times the player's part is put in the determination area 60 or the number of times the controller button is pressed may correspond to the “operation amount”.

  (6) Further, for example, when a game operation is performed when the timing guide mark 36 reaches the direction change position, the generation position and the target position of the timing guide mark 36 may be changed.

  The guide unit 58 of the modified example (6) includes means for determining whether or not a game operation has been performed when a guide image (for example, the timing guide mark 36) changes direction. For example, the guide unit 58 compares the timing at which the timing guide mark 36 reaches the direction change position (that is, the direction change timing) with the operation timing, and acquires the deviation time between them. When the deviation time is within a predetermined range, it is determined that the game operation has been performed when the timing guide mark 36 reaches the direction change position.

  In addition, when it is determined that the game operation is performed when the guide image (for example, the timing guide mark 36) reaches the direction change position, the guide unit 58 determines the generation position and the target position based on the direction change position. The guide image for guiding the reference timing to be visited after the game operation is performed is generated from the changed generation position, and the direction is changed according to the beat of the music. Move toward the target position.

  FIG. 28 is a diagram illustrating how the generation position and the target position are changed. For example, when the determination area 60B is touched when the timing guide mark 36B reaches the direction change position, the guide unit 58 changes the generation position mark 34B to the direction change position. As the position of the generation position mark 34B is changed, the direction change position is also shifted. Note that data indicating the changed generation position and target position may be stored in the game data storage unit 52 in advance. By referring to the data, the generation position and the target position after the change are specified.

  According to the modified example (6), when the game operation is performed when the timing guide mark 36 reaches the direction change position, the interest of the game can be enhanced by changing the generation position.

  In the modification (6), the case where the generation position is changed to the direction change position has been described, but the direction change timing (or the direction change position) is associated with the information indicating the generation position after the change. And may be stored in the game data storage unit 52. When a game operation is performed when the timing guide mark 36 changes direction, the generation position may be changed to a position associated with this direction change timing.

  (7) Further, for example, the determination area 60B corresponding to the generation position mark 34B is at a position where the player can easily touch with the hand, but the determination area 60A corresponding to the generation position mark 34A is relatively above the player's head. It is in a position where it is difficult to touch. Therefore, the difficulty level of the game may be adjusted by exchanging the data content of the reference timing data “A” and the data content of “B” as the game progresses.

  For example, in the reference timing data, when the reference timing for touching the determination area 60A is not set so much and the reference timing for touching the determination area 60B is set to come continuously, by replacing both, The player has to touch the determination area 60A overhead. For example, when the score of the player is relatively increased, the possibility of game over is reduced, so that the difficulty level of the game may be increased as described above.

  The game apparatus 20 according to the modified example (7) further includes means for changing the first reference timing (for example, “A” data) based on the second reference timing (for example, “B” data). . Matching the value of the data “A” at a certain time with the value of the data “B” corresponds to “changing the reference timing” in this modification.

  For example, when the value of the data “A” is “0” and the value of the data “B” is “1” at a certain time, the value of the data “A” is “0”. To "1". Conversely, when the value of “A” data is “1” and the value of “B” data is “0” at a certain point in time, the value of “A” data is “ It may be changed from “1” to “0”.

  FIG. 29 is a diagram illustrating the relationship between the condition relating to the state of the game being executed and the reference timing changing method. The data indicating the relationship of FIG. 29 is stored in the game data storage unit 52, for example.

  The condition relating to the game situation is information indicating a range of values that the game situation data can take, for example, a score range indicated by the game situation data is stored. In addition, for example, in the game being executed, it may be whether or not the elapsed time of the music is in a predetermined range. As a reference timing changing method, information indicating which reference timing is changed and what reference timing is stored.

  For example, the game situation data is referred to and it is determined whether or not the condition shown in FIG. 29 is satisfied. When the condition is satisfied, the reference timing is changed based on the changing method associated with the condition. For example, in the case of the data storage example shown in FIG. 29, when the score indicated by the game situation data falls within a predetermined range, the reference timing data “A” and “B” are switched.

  FIG. 30 is a diagram illustrating an example of data storage when the reference timing is changed. In the data storage example shown in FIG. 30, for example, before the reference timing is changed, the data “A” has a relatively large number of “0” and a small number of “1”. Further, for example, before the reference timing is changed, the data “B” has a relatively large number of “1” and a small number of “0”. When the reference timing is set in this way, there are few opportunities for the player to touch the determination area 60A that is relatively difficult to touch, and there are many opportunities for the player to touch the determination area 60B that is relatively easy to touch. Relatively low.

  On the other hand, as shown in FIG. 30, when the reference timing data “A” and “B” are interchanged, the data “A” is relatively “1” more and “0” less, and the data “B”. However, “0” is relatively large and “1” is small. When the reference timing is set in this way, there are more opportunities for the player to touch the determination area 60A that is relatively difficult to touch, and fewer opportunities for the player to touch the determination area 60B that is relatively easy to touch. Compared to the difficulty of the game.

  When the first reference timing (for example, “A” data) is changed, the guide unit 58 of the modified example (7) has a second generation position (for example, the position of the generation position mark 34 </ b> B) on the game screen 30. ) To a first generation position (eg, the position of the generation position mark 34A) or to move a given image from a second target position to a first target position. Thus, the player is informed that the first reference timing data has been replaced with the second reference timing data.

  FIG. 31 is a screen transition diagram of the game screen 30 when the reference timing is changed. As shown in FIG. 31, when the reference timing data “A” and “B” are interchanged, display control processing is performed such that the occurrence position mark 34A and the occurrence position mark 34B are interchanged. Then, timing guide marks 36 </ b> A are generated continuously from above the player image 32. In this case, the player touches the determination area 60A according to the movement of the timing guide mark 36A.

  According to the modification (7), the difficulty level of the game can be adjusted while the game is in progress.

  In the above description, the case where the reference timing data “A” and “B” are interchanged has been described. However, one reference timing data may be replaced with another reference timing data. It is not restricted to said example. In addition, the occurrence position mark 34 is rotated clockwise, for example, “A” of the reference timing data becomes “B”, “B” becomes “C”, and “C” becomes “D”. The reference timing data may be changed so as to rotate.

  (8) For example, in the embodiment and the modification, the case where the generation position is set around the player image 32 has been described, but the generation position set on the game screen 30 is not limited to this. In addition, it may be arranged in a fan shape with the player image 32 as a reference, or may be arranged in a straight line. Moreover, the number of generation positions may be one.

  For example, although the case where the generation position of the timing guidance mark 36 and the target position are the same has been described, the generation position and the target position may be different.

  FIG. 32 is a diagram illustrating how the timing guide mark 36 moves when the generation position and the target position are different. As shown in FIG. 32, the timing guide mark 36 may depart from the generation position mark 34 and turn toward the target position mark 40 displayed at the target position while changing direction according to the beat of the music. . Here, the timing guide mark 36 moves along a broken line-shaped moving route while repeating the direction change three times in accordance with the music of four beats.

  For example, in the modified example (1), when the generation position is different from the target position, when the timing guide mark 36 is generated, or when the timing guide mark 36 is turned, the target position mark 40 changes. Further, when the generation position and the target position are different in the modified example (5), the movement distance of the timing guide mark 36 is changed by changing the distance between the generation position and the target position according to the operation amount of the game operation. You may make it make it.

  Further, when the generation position and the target position are different in the modified example (6), the position change of the target position mark 40 may be performed in accordance with the position change of the generation position mark 34. In the modification (7), when the generation position and the target position are different, a given image may be moved from the target position mark 40B to the target position mark 40A.

  (9) For example, the case where the timing guide mark 34 moves linearly has been described, but the timing guide mark 34 may move in a curved line. In this case, after being generated from the generation position, the timing guide mark 34 moves on a curve connecting the generation position and the first direction change position, and changes direction when the direction change position is reached. Thereafter, the timing guide mark 34 moves on a curve connecting one direction change position and the next direction change position, and changes direction each time the direction change position is reached. Then, the timing guide mark 34 moves on the curve connecting the last direction change position and the target position, and reaches the target position.

  (10) Further, for example, after the timing guide mark 34 is generated and goes straight for a predetermined period (while a predetermined number of beats are hit), the direction may be changed according to the beat of the music.

  FIG. 33 is a diagram illustrating an example of the game screen 30 of the modification (10). As shown in FIG. 33, after the timing guide mark 36A is generated from the generation position 34A, it may be changed straight after proceeding straight for a predetermined bar toward the target position mark 40A. Also in this case, the direction change is performed at the timing 1 / n measures before the reference timing in the music of n beats.

  In the embodiment, after the timing information mark 34 is generated, the timing information mark 34 changes its direction each time 1 / n measures elapse. In FIG. 33, for example, the timing information mark 34 is During one bar, the vehicle goes straight toward the target position mark 40, and thereafter, the direction is changed every 1 / n bar.

  Moreover, you may combine a modification (9) and a modification (10). That is, after the timing guide mark 34 is generated and moved on the curve for a predetermined period, the direction change of the timing guide mark 34 may be started. In this case, the generation position and the target position may be the same. That is, the timing guide mark 34 may be generated at the generation position and moved on the curve for a predetermined period, and then the timing guide mark 34 may be repeatedly turned to return to the same target position as the generation position.

  (11) Further, for example, in the embodiment or the modification, as an example of the game operation, the player moves the body so as to touch the determination area 60 or the player operates the operation unit 26. However, various known operations can be applied as the game operation. For example, the player's movement of the body so that the player shown in the player image 32 touches the generation position mark 34 may correspond to a game operation.

  (12) For example, in the above description, the example in which the position detection device 1 includes means for generating the player position information based on the captured image and the depth information (depth image) has been described. The means for performing may be included in the game apparatus 20. For example, the game device 20 may receive a captured image and a depth image from the position detection device 1 and generate player position information based on them.

  (13) In the embodiment and the modification, the case where the game apparatus 20 executes a dance game has been described. However, the game apparatus 20 executes a game in which a player performs a game operation according to music. do it.
