[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, 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 by half, 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, in the present embodiment, a case will be described in which the player position information includes at least part information regarding the position of the head and the position of the waist among the plurality of parts of the player 100. For example, the player position information includes the head P1, the shoulder P2, the upper left arm P3, the upper right arm P4, the lower left arm P5, the lower right arm P6, the back P7, the left arm P8, the right arm P9, and the left shin P10. Eleven three-dimensional coordinates corresponding to the right shin P11 are included.

  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 the “generation position” according to the present invention. That is, a plurality of generation positions are set on the game screen 30. Here, a plurality of generation 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, after moving away from the generation position mark 34 with the passage of time, it stops once and moves so as to approach the generation position mark 34. The turning point of the timing guide mark 36 corresponds to the “turning position” according to the present invention. When the reference timing comes, the timing guide mark 36 overlaps the generation position mark 34.

  As shown in FIG. 7, 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, High evaluation is given to the player. 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”.

  Thus, in the game apparatus 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 reciprocates. For example, as compared with the case where the timing guide mark 36 moves in one direction, the player can easily feel the rhythm of the music by the return movement of the timing guide mark 36. As a result, the player can easily grasp the reference timing. Hereinafter, this technique will be described in detail.

Here, the case where the game operation detection unit 40 detects a plurality of types of game operations (a plurality of types of game operations) will be described. For example, the game operation detection unit 40 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 50 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. In the present embodiment, the same number of determination areas 50 as the occurrence position marks 34 (for example, eight) are set. For example, the determination area 50A corresponds to the generation position mark 34A. Similarly, the determination areas 50B to 50H correspond to the generation position marks 34B to 34H.

  For example, the position of the determination area 50 set in the three-dimensional space is determined based on the position of the generation position mark 34.

Area 50 is set. For example, when the occurrence position mark 34 is set around the player image 32 as shown in FIG. 7, the determination area 50 is set around the player's back P7 as shown in FIG.

  The size of the determination area 50 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 area 50 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 area 50, 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 50, it is determined that the game operation has been performed by the player.

  In the present embodiment, eight types of game operations corresponding to the eight determination areas 50A to 50H are detected. The game operation detection unit 40 determines which type of game operation has been performed by determining in which of the determination areas 50A to 50H the player's part indicated by the player position information is located.

  As described above, in the present embodiment, the game operation detection unit 40 captures a captured image (FIG. 2) obtained from the capturing unit 12 that captures the player, and the depth related to the distance between the measurement reference position of the depth measurement unit 13 and the player. 3D position information from position information generating means (for example, position detection device 1) that generates 3D position information (for example, player position information) related to the position of the player in the 3D space based on the information (FIG. 4). Position acquisition means for acquiring the game operation, and the game operation of the player is detected based on the three-dimensional position information.

  Information indicating the position and size of the determination area 50 set in the three-dimensional coordinate space is stored in the game data storage unit 42 described later. Further, the player position information acquired from the position detection device 1 is stored in the game data storage unit 42 in chronological order. Further, the game operation is not limited to touching the determination area 50, and touching the determination area 50 for a certain period of time may correspond to “game operation”.

[6-2. Game data storage unit]
The game data storage unit 42 is realized mainly by the main storage unit 22 and the auxiliary storage unit 23. The game data storage unit 42 stores information necessary for executing the game. For example, the game data storage unit 42 stores the following data.
(1) Music data (data storing general popular music etc. in a predetermined data format)
(2) Reference timing data (3) Determination area data indicating the determination area 50 set in the three-dimensional space (4) Data storing player position information in time series (5) Status of game being executed (score and Game situation data showing elapsed time)

  Of the above data, the music data and the reference timing data are 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.

  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 tempo (rhythm) of music, for example. Here, a case will be described in which the reference timing data indicates a reference timing at which the game operation should be performed for each of a plurality of types of game operations (for example, eight types of game operations).

  FIG. 12 is a diagram illustrating an example of the reference timing data. The t axis shown in FIG. 12 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 1/256 measures. Note that FIG. 12 shows data obtained by dividing one measure into eight parts for the sake of simplicity. That is, the reference timing is shown in units of 1/8 bar.

  As shown in FIG. 12, whether or not the player should perform the game operation at each time point of 1/8 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. 12, the bits “A” to “H” indicate whether or not the player should touch the determination areas 50A to 50H, 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 50A. 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 50A.

  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 areas 50B to 50H, respectively. Yes. Further, 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 areas 50B to 50H, respectively. ing.

  Thus, the timing when at least one of the 8-bit data is “1” is the reference timing, and the data where at least one of the 8-bit data is “1” is the reference timing. The data shown.

  That is, when a first type of game operation (for example, a game operation for touching the determination area 50A) and a second type of game operation (for example, a game operation for touching the determination area 50B) are detected, the reference timing data is First reference timing data (for example, “A” data) indicating a first reference timing for performing the first type of game operation, and a second reference timing for performing the second type of game operation 2nd reference timing data (for example, data of “B”).

  The data stored in the game data storage unit 42 is not limited to the above example. The game data storage unit 42 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 42.

[6-3. Game execution part]
The game execution unit 44 is realized mainly by the control unit 21. The game execution unit 44 executes a game in which the player performs a game operation in accordance with the music. For example, the game execution unit 44 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 46 is realized mainly by the control unit 21. The evaluation unit 46 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 46 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 50. "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. 13 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 42, 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.

[6-5. Guide section]
The guide unit 48 is realized mainly by the control unit 21 and the display unit 27. The guide unit 48 moves the guide image (for example, the timing guide mark 36) from the generation position (for example, the display position of the generation position mark 34) to the turn-back position on the game screen 30 based on the reference timing data, The reference timing is guided to the player by moving the guide image from the return position toward the generation position.

  Here, “the timing guide mark 36 is moved from the return position toward the generation position” means that the timing guide mark 36 is generated from the return position or a position corresponding to the generation position (position within a predetermined distance from the generation position). For example, “moving the timing guide mark 36 back from the return position to the generation position”, “moving the timing guide mark 36 from the return position, and then deleting it from the game screen 30 once. In the vicinity of the generation position (position at a predetermined distance from the generation position), the timing guide mark 36 is displayed again and moved so as to return to the generation position (that is, on the path along which the timing guide mark 36 moves from the return position to the generation position). Hide timing indicator mark 36 in a given section of And “moving the timing guide mark 36 to a predetermined position on the way without returning to the generation position (for example, deleting when the timing guide mark 36 is within a predetermined distance of the generation position)”. is there.

  In the present embodiment, a plurality of generation positions (for example, display positions of the generation position marks 34) are set on the game screen 30, and each of the plurality of generation positions is associated with one of a plurality of game operations. ing. Data indicating this association may be stored in the game data storage unit 42.

  Further, in the present embodiment, the guide unit 48 guides the reference timing for performing the game operation associated with the generation position for each of the plurality of generation positions (for example, the display position of the generation position mark 34). An image (for example, the timing guidance mark 36) is set based on a line from the generation position to a reference position (for example, the display position of the player image 32) on the game screen 30 to the generation position or an extension line thereof. After moving to the position, the guide image is moved from the folding position toward the generation position.

  For example, when the reference timing is included in a predetermined period after the present time (for example, a period from the current time to 2/8 bars later, hereinafter referred to as a guidance target period), the guide unit 48 generates the position where the game screen 30 is generated. A timing guide mark 36 is generated on the mark 34 and is gradually moved toward the turn-back position according to the time difference between the current time and the reference timing, and then the timing guide mark 36 is moved from the turn-back position toward the generation position mark 34. By gradually moving, the timing guide mark 36 is reciprocated.

  FIG. 14 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 is “1” approaches will be described. That is, a case where the timing guide mark 36B is generated from the generation position mark 34B and reciprocates will be described as an example.

  As shown in FIG. 14, the generation position Q is set at the display position of the generation position mark 34B. Further, a turn-back position R that satisfies a predetermined positional relationship with the generation position Q is set on the game screen 30. The positional relationship between the generation position Q and the folding position R may be a predetermined positional relationship. Here, a case will be described in which a position away from the generation position Q by a predetermined distance L in the direction from the display position S to the generation position Q of the player image 32 is set as the folding position R.

  For example, the timing guide mark 36B reciprocates on a line segment connecting the generation position Q and the turn-back position R. That is, the timing guide mark 36B moves on the line drawn from the generation position Q to the turn-back position R as the forward path, and then moves on the line drawn from the turn-back position R to the generation position Q as the return path.

  For example, the timing guidance mark 36B is generated at the generation position Q when a timing 2/8 measures before the reference timing in which the reference timing data “B” is “1” comes. Then, the timing guide mark 36B moves on the forward path so that the distance l between the display position T of the timing guide mark 36B and the generation position Q gradually increases. Further, when a timing 1/8 measure before the reference timing at which “B” of the reference timing data is “1” comes, the timing guide mark 36B reaches the turn-back position R.

  When the timing guide mark 36B reaches the turn-back position R, the return path starts to move. That is, the timing guide mark 36B moves on the return path so that the distance l gradually decreases. When the reference timing with the reference timing data “B” of “1” arrives, the distance l becomes 0, and the timing guide mark 36B overlaps the generation position mark 34B.

  Since the reference timing data is determined based on the tempo of the music (for example, the reference timing data is determined so that the timing at which the music is timed is substantially coincident with the reference timing), the timing guide mark 36B. Is turned back at the turn-back position R (for example, if the music has n beats, the timing before k / n measures of the reference timing, where k and n are positive integers) matches the tempo of the music. Can feel the tempo of the music from the return movement of the timing guide mark 36B, and the timing becomes easy.

  The speed of the timing guide mark 36B may be constant or may change during movement. For example, the speed of the timing guide mark 36B may be changed according to the positional relationship between the timing guide mark 36B and the return position R or the generation position Q. In this case, as the timing guide mark 36B is further away from the generation position Q or the turn-back position R, the speed of the timing guide mark 36B is increased. As the timing guide mark 36B approaches the turn-back position R or the generation position Q, the timing guide mark 36B is increased. The speed of 36B may be decreased.

  In the above description, the timing guide mark 36B has been described as moving, but the same applies to the movement of other timing guide marks 36. That is, the display position of the timing guide mark 36 is adjusted so that the distance l between the timing guide mark 36 and the generation position mark 34 corresponds to the time until the reference timing arrives.

  FIG. 15 is a diagram for explaining the movement of the timing guide mark 36 in time series. For example, while a music is being played, data for a guidance target period (for example, a period from the current time to 2/8 bars 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. 15, when the current time is time t1, the data of “B” at time t3 is “1” within the guidance target period (time t1 to t3). A timing guide mark 36B is generated on the mark 34B.

  When the present time is time t2, since the data of “H” at time t4 is “1” within the guidance target period (time t2 to t4), the timing guidance mark 36H is added to the generation position mark 34H. Occur. Further, the timing guide mark 36B generated at time t1 reaches the return position and starts moving on the return path.

  When the current time is time t3, since the data of “D” at time t5 is “1” within the guidance target period (time t3 to t5), the timing guidance mark 36D is added to the generation position mark 34D. Occur. In addition, since the data of “B” at time t3 is “1” and the reference timing at which the player should touch the determination area 50B has arrived, the timing guide mark 36B that has moved on the return path reaches the occurrence position mark 34B. To do. Note that the timing guidance mark 36 </ b> B may be erased when the player performs a game operation and the evaluation is performed before the arrival. Further, the timing guide mark 36H reaches the return position and starts moving on the return path.

  When the current time is time t4, the data of “H” at time t4 is “1”, and the reference timing at which the player should touch the determination area 50H has come. Therefore, the timing information mark 36H that has moved on the return path Reaches the occurrence position mark 34H. Note that the timing guidance mark 36 </ b> H may be erased when the player performs a game operation and the evaluation is performed before the arrival. Further, the timing guide mark 36D reaches the return position and starts moving on the return path.

  Similar display control is performed at subsequent times. Thus, as the reference timing approaches, the timing guide mark 36 reciprocates radially starting from the generation position, thereby making it easier for the player to feel the rhythm of the music.

[7. Processing executed in game device]
FIG. 16 is a flowchart showing an example of processing executed in the game apparatus 20. The processing in FIG. 16 is executed by the control unit 21 operating according to a program read from the optical disc.

  As shown in FIG. 16, 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 50 (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 50 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 generated position mark 34 corresponds to the positional relationship between the player's back P7 and the determination area 50.

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

  FIG. 17 is a flowchart illustrating an example of the display control process executed in S104. The processing shown in FIG. 17 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. 17, 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 2/8 bars 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 that the time interval U calculated in S203 is the same as the length of the guidance target period (for example, 2/8 bars) or shorter than the length of the guidance target period (for example, 2 / 8 bars and 1/8 bars or more) or a second range shorter than the first range (for example, less than 1/8 bars and 0 bars or more) is determined (S204). ).

  When it is determined that the time interval U is the same as the length of the guidance target period (S204; the length of the guidance target period), the control unit 21 generates the timing guidance 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 determined that the time interval U is within the first range (S204; first range), the control unit 21 displays the display position of the timing guide mark 36A on the forward path so that the time interval U corresponds to the distance l. Is determined (S206). For example, the display position of the timing guide mark 36A is determined such that the distance l increases as the time interval U decreases.

  When it is determined that the time interval U is in the second range (S204; second range), the control unit 21 displays the display position of the timing guide mark 36A on the return path so that the time interval U corresponds to the distance l. Is determined (S207). For example, the display position of the timing guide mark 36A is determined such that the distance l becomes shorter as the difference between the time interval U and the reference timing becomes smaller.

  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. 16, 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. 18 is a flowchart illustrating an example of the game operation evaluation process. The process shown in FIG. 18 is executed for eight game operations corresponding to the determination areas 50A to 50H. Here, a case will be described in which a game operation in which the player touches the determination area 50A is evaluated.

  As shown in FIG. 18, first, the control unit 21 determines whether or not the current time is within the determination period (S301).

  FIG. 19 is a diagram for explaining the determination period. In FIG. 19, the t-axis indicates the time axis. “X” indicates the timing at which the determination area 50A should be touched. That is, “X” indicates the reference timing corresponding to the determination area 50A, and is the time when “A” of the reference timing data is “1”. “Y1” and “Y2” indicate the timing at which the determination area 50A 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. 19 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. 19, 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 50A near the reference timing (X).

  Returning to FIG. 18, 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 50A has been touched in the current determination period. The manipulated flag takes a value of 0 or 1. “0” indicates that the determination area 50A is not touched. On the other hand, “1” indicates that the determination area 50A 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 50A 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 50A.

  If it is not determined that the determination area 50A has been touched (S303; N), the process proceeds to S309. On the other hand, when it is determined that the determination area 50A 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 50A 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” means that the determination area 50A 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. 16, 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 device 20 described above, when the reference timing at which the player should perform the game operation is approaching, the timing guide mark 36 is generated at the generation position mark 34 and the timing guide mark 36 is reciprocated, thereby allowing the player to make a reference. Guide the timing. Since the timing guide mark 36 moves back and forth, it becomes easier for the player to feel the rhythm of the music, and therefore it becomes easier to grasp the reference timing.

  Further, a plurality of generation position marks 34 are displayed on the game screen 30, and a reference timing for performing a game operation associated with each of the plurality of generation position marks 34 is guided by reciprocating the timing guide marks 36 radially. By doing so, even if there are a plurality of types of game operations to be performed by the player, the player can easily grasp which game operation should be performed.

[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 becomes difficult for the player to know which generation mark 34 the timing guidance marks 36 return to. May end up. Therefore, when the timing guide mark 36 is generated, the timing guide mark 36 is returned to which generation position mark 34 by changing the color or size of the generation position mark 34 to which the timing guide mark 36 returns. It may be easy for the player to grasp the above.

  The guide unit 48 of the present modified example displays a generation position image (for example, the generation position mark 34) at the generation position on the game screen 30, and the guide image (for example, the timing guide mark 36) moves from the generation position to the return position. Is started, or when the guide image starts moving from the return position toward the generation position, the generation position image is changed. That is, the guide unit 48 changes the generation position mark 34 when the timing guide mark 36 is generated or when the timing guide mark 36 reaches the return position.

  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 has reached the turn-back position is a case where the timing guide mark 36 is turned back. For example, the timing guide mark 36 is a time that is half the length of the guide target period from the reference timing. This is a case where U is changed from the first range to the second range.

  “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. 20 is a diagram showing a game screen 30 displayed in the modification (1). As shown in FIG. 20, 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, so 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 the movement of the forward path is started, the generation position mark 34 changes.

  In the example shown in FIG. 20, the reference timing data “B” 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 moves back and forth and returns to the generation position mark 34B (that is, when the reference timing comes), the generation position mark 34 returns to the original position. 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 is displayed when the timing guide mark 36 reaches the return position. It may be changed. That is, the generation position mark 34 may be changed when the timing guide mark 36 finishes moving on the forward path and turns back.

  According to the modified example (1), when the generation position mark 34 is changed, it becomes easier for the player to know which generation position mark 34 the timing guide mark 36 returns to. As a result, the player can easily grasp which determination area 50 should be touched.

  (2) Also, 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 marks 36 are moving on the forward path or the returning path. There is. Therefore, the timing guide mark 36 may be changed between when moving on the forward path and when moving on the return path.

  The guide unit 48 of the modified example (2) includes a case where the guide image (for example, the timing guide mark 36) moves from the generation position to the return position and a case where the guide image moves from the return position toward the generation position. Change the guide image. That is, the guide unit 48 makes the timing guide mark 36 different when the timing guide mark 36 is moving on the forward path and when the timing guide mark 36 is moving on the backward path.

  “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, when the time interval U is in the first range, the timing guide mark 36 moves on the forward path, so the timing guide mark 36 takes the first display form (for example, a round shape). When the time interval U is in the second range, the timing guide mark 36 moves on the return path, so the timing guide mark 36 takes a second display form (for example, a star shape) different from the first display form.

  FIG. 21 is a diagram showing a game screen 30 displayed in the modification (2). As shown in FIG. 21, when the timing guide mark 36 moves on the forward path, the timing guide mark 36 becomes a round image. When the timing guide mark 36 reaches the return position and starts moving on the return path, the timing guide mark 36 changes to form a star-shaped image and moves on the return path.

  According to the modified example (2), the timing guidance mark 36 changes between the forward path and the backward path, so that the player can easily grasp whether the timing guidance mark 36 is moving on the forward path or the backward path. Become. As a result, the player can easily grasp the reference timing.

  (3) For example, when a plurality of timing guide marks 36 are moved from a certain occurrence position mark 34, the timing guide marks 36 may overlap each other and become difficult to see. Therefore, the timing guide marks 36 may be prevented from overlapping by shifting the movement paths of the plurality of timing guide marks 36 from each other.

  (3-1) FIG. 22 is a diagram showing a moving route of the timing guide mark 36B in the modified example (3-1). For example, the case where two reference timings in which “B” of the reference timing data is “1” is included in the guidance target period will be described. Of the two reference timings, the earlier one is the first reference timing, and the later one is the second reference timing.

In this case, the guide unit 48 moves the first guide image (for example, the timing guide mark 36B ₁ ) from the generation position Q to the return position R _{0, and} then moves the first guide image from the return position R ₀ to the generation position. The first reference timing is guided to the player by moving toward Q. In addition, the guide unit 48 moves the second guide image (for example, the timing guide mark 36B ₂ ) from the generation position Q to the return position R _{0, and} then moves the second guide image from the return position R ₀ to the generation position Q. The second reference timing that comes after the first reference timing is guided to the player.

In addition, the guide unit 48 operates in the state where the first guide image (for example, the timing guide mark 36B ₁ ) is moving from the return position R ₀ toward the generation position Q, for example, the second guide image (for example, the timing guide mark). If the mark 36B ₂₎ is moved toward the return position R ₀ from the generation position Q, a path first guide image moves toward the generation position Q from the return position R _0, the second guide image generation position The path moving from Q toward the turn-back position _R0 is made different.

For example, as shown in FIG. 22, the game screen 30, and the timing indicator mark 36B ₁ is moved to the backward, when the timing indicator mark 36B ₂ moving on the forward path, both paths of are set at different positions The For example, a first curve CL ₁ connecting the generation position Q and the turn-back position R ₀ is defined as the forward path, and a second curve CL ₂ different from the _first curve CL ₁ is defined as the return path. Data indicating the first curve CL ₁ and the second curve CL ₂ may also be stored in advance in the game data storage unit 42.

  According to the modified example (3-1), it is possible to prevent the timing guide marks 36 from overlapping each other and becoming difficult to see.

(3-2) The method for shifting the path of the timing indicator mark 36B ₁ and the timing indicator mark 36B ₂ is not limited to the above example. Shifting Additional e.g., the folded position of the timing indicator mark 36B _1, the folded position of the timing indicator mark 36B _2, by shifting the, and the return of the timing indicator mark 36B _1, and forward the timing indicator mark 36B _2, the You may do it.

FIG. 23 is a diagram illustrating a method of determining the movement route of the timing guide mark 36 in the modified example (3-2). As shown in FIG. 23, the return position _{R 1} of the timing indicator mark 36B _1, and return position _{R 2} of the timing indicator mark 36B _2, by made different, and forward and backward timing indicator mark 36B _1, the timing indicator mark a forward path and backward path 36B _2, may be shifted.

For example, a position that is rotated counterclockwise by an angle θ from the original folding position R ₀ as the reference is the folding position R ₁ . Further, for example, from the original return position R _0, and the position R ₂ folded position rotated by an angle θ clockwise with respect to the generation position Q.

The guide unit 48 of the modified example (3-2) moves the first guide image (for example, the timing guide mark 36B ₁ ) from the generation position Q to the first return position R _{1, and} then the first guide image. by moving toward the generation position Q from the first return position R _1, it guides the first reference timing to the player.

In addition, the guide unit 48 gives the player a second reference timing that comes after the first reference timing in a state where a _first guide image (for example, the timing guide mark 36B ₁ ) is displayed on the game screen 30. In the case of guidance, the second guidance image (for example, the timing guidance mark 36B ₂ ) is moved from the generation position Q to the second folding position R ₂ different from the _first folding position R _1, and then the second guidance image. by moving towards the guide image from the second return position R ₂ generation position Q, to guide the second reference timing to the player.

  According to the modified example (3-2), it is possible to prevent the timing guide marks 36 from overlapping each other and becoming difficult to see.

  (3-3) The modification (3-1) and the modification (3-2) may be combined. For example, data indicating the movement route of the timing guide mark 36 may be associated with each reference timing indicated by the reference timing data.

  FIG. 24 is a diagram illustrating the association between the reference timing and the movement path of the timing guide mark 36 that guides the reference timing. Data indicating the association may be stored in the game data storage unit 42. As the movement route, for example, any one of a route different from the forward route and the return route as shown in the modification example (3-1) and a route for changing the return position as shown in the modification example (3-2) are used. Information to be stored is stored.

  When a plurality of reference timings are included in the guidance target period, the guide unit 48 moves the timing guide mark 36 that guides each of the plurality of reference timings based on the movement route associated with the reference timing.

  According to the modification (3-3), it is possible to set the movement route of the timing guide mark 36 when a plurality of reference timings are included in the guidance target period.

  (4) Further, for example, an image other than the timing guide mark 36 may move on the forward path and the return path of the timing guide mark 36. In this case, the player can play the game without being confused by the image, so that the game preference 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 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.

  The game apparatus 20 of the modified example (4) moves a given image (for example, the obstruction mark 38B) on the game screen 30 without folding the line from the generation position to the folding position and the extended line thereof at the folding position. Including means for causing The means is realized by the game execution unit 44, for example. The obstruction mark 38B moves on the forward path of the timing guide mark 36B to reach the return position, and then moves without being returned. That is, as shown in FIG. 24, the game screen 30 may be erased from the game screen 30 while moving in the forward direction.

  The obstruction 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 (4), the interest of the game can be improved by displaying the interference mark 38 on the game screen 30.

  (5) Further, for example, the moving distance of the timing guidance mark 36 for guiding the subsequent reference timing changes according to the amount of game operation performed when the reference timing arrives. You may make it raise. For example, the moving distance of the timing guide mark 36 for guiding the next reference timing may be changed according to the speed of the part when the player touches the determination area 50.

  The game operation detection unit 40 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 48 includes means for determining the distance between the generation position and the return position based on the operation amount of the game operation when the game operation is evaluated. The guide unit 48 moves a guide image (for example, the timing guide mark 36) that guides the reference timing to be visited after the game operation is performed to a turn-back position that is a determined distance away from the generation position. The guide image is moved from the folding position toward the generation position. Here, the distance between the generation position and the return position is determined based on the change in the player position information.

  FIG. 26 is a diagram illustrating the association between the change in the player position information, the distance between the generation position and the return position. The data indicating the association is stored in the game data storage unit 42, for example. As shown in FIG. 26, for example, the amount of change (or speed) of each part of the player indicated by the player position information is associated with information indicating the distance.

  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.

  As information indicating the distance between the generation position and the return position, for example, information indicating in which direction and how far away the return position is set when viewed from the generation position is stored. Here, a case where three types of information “close”, “normal”, and “far” are stored as the information indicating the distance will be described. For example, information on the distance L between the generation position and the turn-back position is stored.

  When the game operation is evaluated, the guide unit 48 refers to the time-series change in the player position information stored in the game data storage unit 42 and specifies the amount of change in the part corresponding to the game operation. . And the guidance part 48 determines a return position based on the distance linked | related with the said specified variation | change_quantity.

  FIG. 27 is a diagram illustrating a return position according to a change in player position information. Here, a case will be described as an example where the player performs a game operation that touches the determination area 50B with the right hand when the reference timing whose reference timing data “B” is “1” arrives. First, the amount of change 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 50B.

When the amount of change in the player's lower right arm P6 is “small”, as shown in FIG. 27, the turn-back position R _{N at} a position away from the generation position Q (the display position of the generation position mark 34B) by a distance L / 2. Is determined. When the amount of change of the player's lower right arm P6 is “normal”, as shown in FIG. 27, the turn-back position R ₀ is located at a distance L from the generation position Q (display position of the generation position mark 34B). It is determined. When the change amount of the player's lower right arm P6 is “large”, as shown in FIG. 27, the turn-back position R at a position 3L / 2 away from the generation position Q (the display position of the generation position mark 34B). _F is determined.

  Then, the timing guide mark 36B that guides the reference timing to be visited after the return position is determined as described above moves toward the determined return position as described above. The turn-back position is determined again according to the game operation performed at the reference timing.

  According to the modification (5), the movement distance of the timing guide mark 36 for guiding the next reference timing can be changed in accordance with the position change of the player's part at the reference timing, so that the game's interest is improved. be able to.

  In the embodiment, the case where the game operation is detected based on the player position information has been described. However, pressing each button provided on the controller of the operation unit 26 corresponds to “game operation”. It may be. In this case, the return position may be determined according to the strength with which the player presses the button of the operation unit 26. For example, the return position may be set such that the return position is further away from the generation position as the player strongly presses the operation unit 26.

  In this case, the game operation detection unit 40 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 40 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 40 detects a pressure applied to the button by obtaining a detection signal from the pressure sensor from the operation unit 26.

  Also in this case, the movement distance 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 distance between the generation position and the turn-back position. The interest 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 50 or the number of times the controller button is pressed may correspond to the “operation amount”.

  (6) In addition, for example, when a game operation is performed when the timing guide mark 36 reaches the turn-back position, the interest of the game is improved by changing the position where the timing guide mark 36 is generated or the turn-back position. It may be.

  The guide unit 48 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) reaches the return position. The case where the timing guide mark 36 reaches the return position is a case where the timing guide mark 36 returns from the forward path to the return path and starts moving.

  For example, the guide unit 48 compares the timing at which the timing guide mark 36 reaches the turn-back position (for example, the timing before 1/8 bar of the reference 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 turn-back 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 turn-back position, the guide unit 48 changes the generation position based on the turn-back position. Means for changing the return position based on the generated position, and after moving the guide image for guiding the reference timing to be visited after the game operation is performed from the changed occurrence position to the changed return position, The guide image is moved from the changed folding position toward the changed generation position.

  FIG. 28 is a diagram illustrating how the generation position is changed. For example, when the determination area 50B is touched when the timing guide mark 36B reaches the return position, the guide unit 48 changes the generation position mark 34B to the position of the return position. As the position of the generation position mark 34B is changed, the folding position is also changed. For example, a position that is a distance L away from the changed generation position mark 34B is set as the folding position.

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

  Further, the method of changing the generation position is not limited to the above example. The generation position may be changed to a position different from the generation position before the game operation is performed when the timing guide mark 36 reaches the turn-back position. The folding position may be determined at a position corresponding to the change in the generation position.

  (7) Further, for example, the determination area 50B corresponding to the generation position mark 34B is at a position where the player can easily touch it, but the determination area 50A corresponding to the generation position mark 34A is above the player's head. It is in a position where it is difficult to touch. Therefore, as the game progresses, the difficulty level of the game may be adjusted by replacing the data “A” of the reference timing data with the data “B”.

  For example, in the reference timing data, when the reference timing for touching the determination area 50A is not set so much and the reference timing for touching the determination area 50B is set so as to come continuously, by replacing both, The player has to touch the overhead determination area 50A continuously. 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 replacing the first reference timing data (for example, “A” data) with the second reference timing data (for example, “B” data). For example, the data “A” and the data “B” shown in the reference timing data are interchanged.

  FIG. 29 is a diagram illustrating a relationship between a condition relating to the state of a game being executed and a reference timing replacement method. Data indicating the relationship of FIG. 29 is stored in the game data storage unit 42, 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 replacement method, information indicating which reference timing data is replaced with what reference timing data 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. If the condition is satisfied, the reference timing is replaced based on the replacement 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 data is replaced. In the data storage example illustrated in FIG. 30, for example, before the reference timing is changed, the data “A” is relatively “0” and “1” is small. For example, before the reference timing is changed, the data “B” is relatively “1” and “0” is small. When the reference timing is set in this way, there are few opportunities for the player to touch the determination area 50A that is relatively difficult to touch, and there are many opportunities for the player to touch the determination area 50B 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 50A that is relatively difficult to touch, and fewer opportunities for the player to touch the determination area 50B that is relatively easy to touch. Compared to the difficulty of the game.

  When the first reference timing data (for example, “A” data) is replaced with the second reference timing data (for example, “B” data), the guide unit 48 of the modified example (7) At 30, a first reference timing is obtained by moving a given image from a second generation position (eg, the position of the generation position mark 34B) to a first generation position (eg, the position of the generation position mark 34A). The player is informed that the 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 data is exchanged. 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 50A 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.

  (9) 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 50, 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.

  (10) 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.

  (11) In the embodiment and the modified example, 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.
