  Hereinafter, examples of embodiments 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, an arcade game machine, a mobile phone, a personal digital assistant (PDA), or a personal computer. . 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 shows a hardware configuration of a game device according to an embodiment of the present invention. The game device 10 shown in FIG. 1 includes a consumer game machine 11, a display unit 34, an audio output unit 36, an optical disc 38 (information storage medium), and a player detection unit 40. The display unit 34 and the audio output unit 36 are connected to the consumer game machine 11. For example, a home television receiver or a liquid crystal display is used as the display unit 34, and for example, a speaker or headphones incorporated in the home television receiver is used as the audio output unit 36.

  The home game machine 11 is a known computer system. The home game machine 11 includes a bus 12, a control unit 14, a main memory 16, an image processing unit 18, an input / output processing unit 20, an audio processing unit 22, an optical disk drive 24, a hard disk 26, a communication interface 28, a controller 30, and an external device. Interface 32 is included. The bus 12 is for exchanging addresses and data among the units of the consumer game machine 11.

  The control unit 14 includes one or a plurality of microprocessors. The control unit 14 executes control processing and information processing of each unit based on a program read from the optical disc 38. The main memory 16 includes, for example, a RAM, and a program and data read from the optical disk 38 are written into the main memory 16. The main memory 16 is also used as a working memory for the control unit 14. The image processing unit 18 includes a VRAM, and draws a screen on the VRAM based on the image data supplied from the control unit 14. The screen drawn on the VRAM is converted into a video signal and output to the display unit 34.

  The input / output processing unit 20 is an interface for the control unit 14 to access the audio processing unit 22, the optical disk drive 24, the hard disk 26, the communication interface 28, the controller 30, and the external interface 32. The sound processing unit 22 includes a sound buffer, and the sound data read out to the sound buffer is output from the sound output unit 36. The communication interface 28 is an interface for connecting the consumer game machine 11 to a communication network such as the Internet by wire or wireless.

  The optical disk drive 24 reads programs and data recorded on the optical disk 38. The hard disk 26 is a general hard disk device (auxiliary storage device). Here, the optical disc 38 is used to supply programs and data to the consumer game machine 11, but other information storage media such as a memory card may be used. Note that, for example, a program or data may be supplied to the consumer game machine 11 from a remote place via a communication network. Further, programs and data described as being stored on the optical disk 38 may be stored on the hard disk 26.

  The controller 30 is an operation unit for the player to operate. The input / output processing unit 20 scans the state of each operation member of the controller 30 at regular intervals (for example, every 1/60 seconds), and supplies an operation signal representing the scan result to the control unit 14 via the bus 12.

  The external interface 32 is an interface for connecting peripheral devices. In the case of this embodiment, the player detection unit 40 is connected to the external interface 32. Here, the player detection unit 40 is described as being connected to an external interface as a peripheral device, but the player detection unit 40 may be built in the consumer game machine 11.

  The player detection unit 40 detects the position of a representative part of the player (for example, the head, waist, right wrist, left wrist, right ankle, or left ankle). By using the detection result of the player detection unit 40, it is possible to determine the posture and movement of the player. For this reason, in the game apparatus 10, for example, it is possible to execute a game in which a player moves by playing his / her body without using the controller 30.

  The player detection unit 40 will be described in more detail. FIG. 2 shows a hardware configuration of the player detection unit 40. FIG. 3 is a diagram showing a state where the player plays the game. The player detection unit 40 will be described with reference to these drawings.

  As shown in FIG. 2, the player detection unit 40 includes a control unit 41, a storage unit 42, a voice input unit 43, a photographing unit 44, a depth measurement unit 45, and a bus 46. The bus 46 is used for exchanging addresses and data among the units of the player detection unit 40.

  The control unit 41 includes one or a plurality of microprocessors, and executes processing based on a program stored in the storage unit 42. The storage unit 42 stores a program executed by the control unit 41. In addition, the storage unit 42 is used to store various data acquired by the voice input unit 43, the imaging unit 44, or the depth measurement unit 45. The voice input unit 43 includes a microphone, for example. For example, the voice input unit 43 is used to acquire a voice emitted from the player P.

  The photographing unit 44 includes, for example, a CCD camera. The imaging unit 44 generates a captured image (for example, an RGB digital image) every predetermined time (for example, 1/60 seconds), for example. As shown in FIG. 3, the player detection unit 40 is installed in the vicinity of the display unit 34, and the imaging unit 44 captures an area in front of the display unit 34. As shown in FIG. 3, the player P is located in the front area of the display unit 34 and plays the game, and therefore the player P appears in the captured image of the imaging unit 44. FIG. 4 shows an example of a photographed image.

  The depth measurement unit 45 includes, for example, an infrared sensor. For example, the infrared sensor includes an infrared light emitting element and an infrared light receiving element (for example, an infrared diode). The infrared sensor emits infrared light, and detects reflected light when the irradiated infrared light is reflected by a person or an object.

  FIG. 5 is a diagram for explaining irradiation of infrared light and detection of reflected light. As shown in FIG. 5, pulsed infrared light is emitted from the depth measurement unit 45 (infrared light emitting element) at a predetermined interval. The infrared light emitted from the depth measurement unit 45 spreads in a spherical shape with the position of the infrared light emitting element as a center point, and hits the surface of a person (player P) or an object. The infrared light hitting these surfaces is reflected, and the reflected infrared light is detected by the infrared light receiving element of the depth measurement unit 45. That is, the reflected light in which the phase of the irradiated infrared light is inverted by 180 degrees is detected.

  As shown in FIG. 5, when the player P projects both hands forward, the projected both hands are closer to the depth measuring unit 45 (infrared sensor) than the player P's body. In this case, the flight time (TOF: Time of Flight) of the infrared light reflected by both hands of the player P is shorter than the flight time of the infrared light reflected by the player P's body. The “flight time” is the time from when the infrared light is irradiated until the reflected light is received.

  The depth measurement unit 45 measures the depth (depth) of each pixel in the captured image of the imaging unit 44 based on the detection result of the reflected light. The “pixel depth” is the distance from the measurement reference position to the portion of the subject imaged on the pixel. For example, the depth of the pixel in the area where the right hand of the player P is photographed is the distance from the measurement reference position to the right hand of the player P. Further, the “measurement reference position” is a position serving as a reference when measuring the depth, for example, the position of the infrared sensor.

  Specifically, the depth measurement unit 45 measures the depth based on the flight time from when the infrared light is irradiated until when the reflected light is received. For example, the value obtained by dividing the product of the time from irradiation of infrared light to the detection of reflected light (that is, the flight time) and the speed of the infrared light by 2 is the infrared light from the measurement reference position. Corresponds to the distance (ie depth) to the reflected person or object. By executing such processing, the depth measuring unit 45 acquires the depth described above.

  The measurement result of the depth measurement unit 45 is represented as an image. For example, the measurement result of the depth measurement unit 45 is represented as a grayscale image. Similar to the imaging unit 44, the depth measurement unit 45 also measures the depth every predetermined time (for example, 1/60 seconds), and generates an image representing the measurement result (hereinafter referred to as “depth image”).

  FIG. 6 is a diagram illustrating an example of a depth image. The depth image illustrated in FIG. 6 is an image indicating the depth of each pixel of the captured image illustrated in FIG. In the depth image shown in FIG. 6, the hatched area (for example, the background of the player P), the dot area (for example, the head and the body of the player P), and the hatched and dotted lines And a white region (for example, both hands of the player P). The hatched area indicates that the luminance is lower than that of the dot area and the white area, and the dot area indicates that the luminance is lower than that of the white area.

  In the depth image, the depth is represented by luminance (pixel value). In the depth image shown in FIG. 6, the luminance increases as the depth decreases (that is, the distance from the depth measurement unit 45 decreases). For example, as shown in FIG. 5, when the player P projects both hands forward, both hands of the player P are closer to the depth measuring unit 45 than the body of the player P. For this reason, in the depth image shown in FIG. 6, the luminance of the pixels corresponding to both hands of the player P is higher than the luminance of the pixels corresponding to the trunk of the player P. In the depth image, the luminance may be increased as the depth increases (that is, the distance from the depth measurement unit 45 increases).

  The player detection unit 40 acquires posture data related to the posture of the player P based on the captured image of the imaging unit 44 and the depth image acquired by the depth measurement unit 45.

  For example, the player detection unit 40 detects a pixel corresponding to the contour of the player P by detecting a portion where the depth changes greatly in the depth image. If no person or object is located around the player P, the flight time of the infrared light irradiated toward the player P and the flight time of the infrared light irradiated toward the peripheral area of the player P are greatly different. It will be. As a result, the depth differs greatly between the player P and the peripheral area of the player P. For this reason, it is possible to detect the contour of the player P by detecting a portion where the depth has greatly changed.

  The method for detecting the contour of the player P is not limited to the above method. For example, it is also possible to detect the contour of the player P by detecting a portion where the luminance of the pixel is greatly changed in the captured image.

  Next, the player detection unit 40 refers to color information (RGB brightness) of pixels surrounded by the contour of the player P in the captured image. And the player detection part 40 specifies the pixel corresponding to each site | part of the player P based on the color information of a pixel. 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 player P) from the image by comparison with the comparison image can be applied.

  Based on the pixel position (two-dimensional coordinates in the captured image or depth image) and the depth specified as described above, the player detection unit 40 is a representative part of the player P (for example, head, waist, right wrist, left hand). Neck, right ankle, or left ankle) is calculated. For example, the player detection unit 40 calculates the three-dimensional coordinates of the part of the player P by performing a predetermined matrix conversion process on the position and depth of the pixel corresponding to the part. This line example conversion process is executed by the same process as the world coordinate-screen coordinate conversion process in the three-dimensional graphics technology, for example.

  Further, the three-dimensional coordinates of the part of the player P are expressed as coordinate values in the XeYeZe coordinate system having the origin Oe as the position of the player detection unit 40 (imaging unit 44), for example, as shown in FIG. In FIG. 7, the Ze axis direction is, for example, the line-of-sight direction of the photographing unit 44 (CCD camera). The Xe-axis direction is a direction orthogonal to the Ze-axis direction, and corresponds to the left-right direction when viewed from the player detection unit 40 (shooting unit 44). Furthermore, the Ye-axis direction is a direction orthogonal to both the Ze-axis direction and the Xe-axis direction, and corresponds to the vertical direction when viewed from the player detection unit 40 (shooting unit 44).

  Data indicating the three-dimensional coordinates of each part of the player P acquired as described above corresponds to the posture data of the player P. FIG. 8 shows an example of the posture data of the player P. The posture data of the player P shown in FIG. 8 includes three-dimensional coordinates of the player P's head P1, left wrist P2, right wrist P3, waist P4, left ankle P5, and right ankle P6. Note that three-dimensional coordinates other than the above-described parts may be included in the posture data of the player P.

  The posture data of the player P is acquired, for example, every predetermined time (for example, 1/60 seconds) and supplied from the player detection unit 40 to the consumer game machine 11. The control unit 14 can grasp the posture of the player P (the position of each part of the player P) based on the posture data of the player P. Moreover, the control part 14 can also grasp | ascertain the motion of the player P's body by grasping | ascertaining the change of the attitude | position of the player P (change of the position of each part of the player P).

  In the game apparatus 10 having the above-described configuration, a game in which the player P plays with his / her body moving in the front area of the display unit 34 is executed by a program stored on the optical disc 38. For example, a game in which the player P dances according to music is executed on the game device 10.

  FIG. 9 shows an example of a game screen displayed on the display unit 34. The score 50 of the player P is displayed on the game screen shown in FIG. A character object 52 is displayed on the game screen. For example, the character object 52 is a game character object representing a dancer. In addition to the character object 52, a game character object representing a back dancer may be displayed on the game screen.

  The character object 52 dances to music. The character object 52 serves to guide the player P about the dance that the player P should perform. In this game, the player P aims to dance while watching the character object 52 in the same manner as the dance that the character object 52 dances.

  In the game screen shown in FIG. 9, the character object 52 is displayed so as to face the player P, and the character object 52 performs the dance that the player P should perform in the right and left direction.

  Therefore, for example, when the character object 52 moves the right hand as viewed from the player P (ie, the left hand 54l) in the right direction as viewed from the player P (ie, the left direction as viewed from the character object 52), the player P moves the right hand to the right in the same way. Further, for example, when the character object 52 moves the left hand as viewed from the player P (ie, the right hand 54r) in the left direction as viewed from the player P (ie, the right direction as viewed from the character object 52), the player P Similarly, move your left hand to the left.

  In this game, the player's evaluation of the dance is determined as described below. That is, in this game, a plurality of reference timings are set. Then, the posture that the player P actually took at the reference timing is compared with the posture (model posture) that the player P should take at the reference timing. For example, when the degree of similarity between the posture that the player P has actually taken and the model posture is high, the evaluation with respect to the player P becomes high. On the other hand, when the degree of similarity between the posture that the player P has actually taken and the model posture is low, the evaluation with respect to the player P is low.

  In this game, the player P is guided about the arrival of the reference timing and the model posture that the player P should take at the reference timing. As a result, the player P can easily predict the arrival of the reference timing and the model posture that the player P should take at the reference timing.

  FIG. 10 shows another example of the game screen. In addition to the character object 52, two guidance objects 56 are displayed on the game screen shown in FIG. The guidance object 56 plays a role of guiding (notifying) the player P of the reference timing and the model posture that the player P should take at the reference timing.

  When the arrival of the reference timing approaches, the guidance object 56 is displayed on the game screen. Specifically, when the remaining time until the reference timing reaches a predetermined time (for example, the time corresponding to one measure of the music), the two guide objects 56 are different from the position of the character object 52. Displayed at the initial position. One guide object 56 is displayed on the right side of the character object 52 when viewed from the player P, and the other guide object 56 is displayed on the left side of the character object 52 when viewed from the player P.

  The guide object 56 is a silhouette of the character object 52 at the reference timing. That is, the guidance object 56 represents the posture that the character object 52 takes at the reference timing.

  Further, after being displayed at the initial position, the guide object 56 moves toward the character object 52 as shown in FIG. At the reference timing, the guide object 56 reaches the character object 52 and overlaps with the character object 52. As described above, since the posture of the guide object 56 is the posture of the character object 52 at the reference timing, the character object 52 and the guide object 56 are completely overlapped at the reference timing. The guidance object 56 disappears from the game screen after completely overlapping the character object 52.

  The player P can predict the arrival of the reference timing by referring to the guide object 56 that moves toward the character object 52. In addition, the player P can predict the posture that the player P should take at the reference timing by referring to the posture of the guidance object 56.

  Hereinafter, a configuration for realizing the above guidance function will be described.

  A virtual space is constructed in the main memory 16 to display the game screens shown in FIGS. First, this virtual space will be described. FIG. 11 is a diagram illustrating an example of a virtual space. The state of the virtual space 60 shown in FIG. 11 corresponds to the game screen shown in FIG. A virtual space 60 shown in FIG. 11 is a virtual three-dimensional space in which three coordinate axes (Xw, Yw, Zw axes) orthogonal to each other are set.

  As shown in FIG. 11, a floor object 62 representing a floor is arranged in the virtual space 60. Further, in the virtual space 60 shown in FIG. 11, the character object 52 and the two guide objects 56 are arranged on the floor object 62. The guidance object 56 is not always arranged in the virtual space 60, but is arranged in the virtual space 60 when the reference timing approaches.

  The character object 52 includes a plurality of polygons. A skeleton for controlling the posture of the character object 52 is set inside the character object 52. The skeleton includes a plurality of joints corresponding to joints and a plurality of bones for connecting the joints. By changing the state of these joints and bones (for example, position and rotation angle), the position of each part (for example, the head, waist, left wrist, right wrist, left ankle, or right ankle) of the character object 52 is changed. As a result, the posture of the character object 52 changes.

  The guide object 56 has the same structure as the character object 52. However, the color of each vertex of the guide object 56 is set to a predetermined color (for example, green).

  Further, a virtual camera 64 (viewpoint) is set in the virtual space 60. Then, the virtual space 60 viewed from the virtual camera 64 is displayed on the game screen. The position of the virtual camera 64, the line-of-sight direction 66, and the angle of view are set so that the character object 52 is always displayed in a predetermined area (for example, the central area) in the game screen.

  In the case of this embodiment, the character object 52 dances at substantially the same position. Further, the position of the virtual camera 64, the line-of-sight direction 66, and the angle of view are also fixed, and the positional relationship between the character object 52 and the virtual camera 64 is fixed. Note that when the character object 52 dances while moving, the position of the virtual camera 64, the line-of-sight direction 66, and the angle of view may be set based on the position of the character object 52.

  Next, functional blocks realized by the game apparatus 10 will be described. FIG. 12 is a functional block diagram mainly showing functional blocks related to the guidance function among the functional blocks realized by the game apparatus 10. As shown in FIG. 12, the game apparatus 10 includes a storage unit 70, a guide unit 72, a posture data acquisition unit 74, and an evaluation unit 76.

  The storage unit 70 is realized by at least one of the main memory 16, the hard disk 26, and the optical disk 38, for example. Note that the storage unit 70 may be realized by a storage device provided in another device that is connected to the game apparatus 10 via a communication network. Functional blocks other than the storage unit 70 are realized, for example, when the control unit 14 executes a program read from the optical disc 38.

  First, the storage unit 70 will be described. The memory | storage part 70 memorize | stores various data required in order to run a game.

  For example, the storage unit 70 stores music data. The music data is obtained by storing general popular music or the like in a predetermined data format.

  For example, the storage unit 70 stores model data of the character object 52. The model data is data indicating the shape of the character object 52.

  For example, the storage unit 70 stores motion data of the character object 52. The motion data is data that defines the posture of the character object 52 in each frame when the character object 52 performs an action. As described above, the posture of the character object 52 is controlled by controlling the skeleton state. For this reason, the posture of the character object 52 is represented by the skeleton state of the character object 52.

  By changing the posture of the character object 52 according to the motion data, the character object 52 moves. Hereinafter, changing the posture of the character object 52 according to the motion data is referred to as “playing back the motion data”.

  In the case of the present embodiment, motion data for causing the character object 52 to perform an action corresponding to the exemplary action to be performed by the player P is stored in the storage unit 70. Specifically, motion data for causing the character object 52 to perform a dance (exemplary action) to be performed by the player P in the opposite direction is stored in the storage unit 70. In the motion data, a change in the posture of the character object 52 during the period in which the music is being played is defined. This motion data is reproduced in synchronization with the reproduction of the music data. As a result, the character object 52 dances in reverse to the dance that the player P should perform in accordance with the music.

  For example, the storage unit 70 stores data related to the reference timing. In addition, the storage unit 70 stores data related to the model posture that the player P should take at the reference timing.

  FIG. 13 shows an example of reference data stored in the storage unit 70. The reference data shown in FIG. 13 is data indicating the reference timing and the model posture that the player P should take at the reference timing. In FIG. 13, the t-axis is a time axis and indicates the passage of time since the reproduction of music was started.

  In the reference data, for example, the reference timing is indicated in units of 1/256 measures of music. In the reference data shown in FIG. 13, for the sake of convenience, the reference timing is shown in units of 1/8 bar of music. In the reference data shown in FIG. 13, whether or not each time point is the reference timing is indicated by 1-bit data. “0” indicates that the time is not the reference timing, and “1” indicates that the time is the reference timing.

  In the reference data shown in FIG. 13, the model posture data is associated with the time point that is the reference timing. This model posture data is data indicating the model posture that the player P should take at the reference timing. For example, the model posture data is representative parts of the player P when the player P assumes the model posture (for example, the head P1, the left wrist P2, the right wrist P3, the waist P4, the left ankle P5, and the right ankle P6). Etc.). Note that the position of each part is represented by coordinate values in the XeYeZe coordinate system, for example, similarly to the posture data shown in FIG.

  In the reference data, the reference timing may be indicated by using an elapsed time from the start of music reproduction (or game execution). That is, the reference data indicates that the reference timing is the time point when the elapsed time from the start of the music playback is T1, T2, T3,... Seconds (T1, T2, T3: numerical value). You may do it.

  Alternatively, in the reference data, the reference timing may be indicated using the data amount of the reproduced music data. That is, in the reference data, it is indicated that the time point when the data amount of the reproduced music data becomes D1, D2, D3,... Bytes (D1, D2, D3: numerical value) is the reference timing. Also good.

  By the way, in this embodiment, the exemplary action (dance) to be performed by the player P and the action (dance) performed by the character object 52 have a certain relationship. That is, as described above, the character object 52 performs the dance that the player P should perform in the left-right direction. For this reason, it is also possible to specify the model posture that the player P should perform at the reference timing based on the motion data of the character object 52. Therefore, the motion data of the character object 52 may be used as “data regarding the model posture that the player P should take at the reference timing”. In this case, the “model posture data” field can be omitted in the reference data shown in FIG.

For example, the storage unit 70 stores game situation data indicating the current situation of the game. For example, the following information is included in the game situation data.
(1) Music playback position information (information indicating which bar of the music is currently being played back)
(2) Motion data playback position information of the character object 52 (information indicating which frame of the motion data is currently being played back)
(3) State information (for example, position) of the character object 52
(4) State information (for example, position) of the guide object 56
(5) State information of the virtual camera 64 (for example, position, line-of-sight direction 66, angle of view, etc.)
(6) Score information of player P

  Next, the guide part 72 is demonstrated. The guide unit 72 guides the player P about the reference timing and the model posture that the player P should take at the reference timing.

  The guide unit 72 displays a game screen representing the virtual space 60 viewed from the virtual camera 64 on the display unit 34. Then, when the remaining time until the reference timing arrives reaches a predetermined time, the guide unit 72 causes the first object having a posture corresponding to the model posture that the player P should take at the reference timing to be in the virtual space 60. It is arranged at a position different from the reference position 67 set to. Further, the guide unit 72 guides the player P about the reference timing and the model posture that the player P should take at the reference timing by moving at least one of the first object and the reference position 67 toward the other.

  More specifically, for example, in the virtual space 60, a second object that performs an action corresponding to the exemplary action that the player P should perform is arranged, and the guide unit 72 has a second object posture at the reference timing. Arrange one object. And the guide part 72 performs said guidance by moving a 1st object toward a 2nd object. In this case, the position of the second object corresponds to the “reference position 67” described above. However, a position other than the position of the second object may be set as the “reference position 67” described above.

  In the case of this embodiment, the time corresponding to n bars of the music to be played corresponds to the “predetermined time”. “N” represents an arbitrary numerical value, for example, “1”. In addition, the guide object 56 corresponds to the “first object” described above, and the character object 52 corresponds to the “second object” described above. Further, the position of the character object 52 corresponds to the “reference position 67”.

  In the present embodiment, the guide unit 72 arranges two guide objects 56 (first objects) on the floor object 62 when the time until the reference timing arrives reaches a predetermined time. Here, the position control of the guide object 56 will be described in more detail. FIG. 14 is a diagram for explaining an example of position control of the guide object 56. In FIG. 14, a straight line 80 is a straight line extended from the position of the virtual camera 64 to the position of the character object 52. The straight line 80 may be a straight line indicating the line-of-sight direction 66 of the virtual camera 64.

  The initial position 68 of the guide object 56 is set based on the positions of the character object 52 and the virtual camera 64. As shown in FIG. 14, the initial position 68 of the guide object 56 is set on a straight line 82 orthogonal to the straight line 80.

  The initial position 68 of one guide object 56 is set on the left side of the character object 52 when viewed from the virtual camera 64, and the initial position 68 of the other guide object 56 is set on the right side of the character object 52 when viewed from the virtual camera 64. Is done. The initial positions 68 of the two guide objects 56 are set so that the character object 52 is positioned on a straight line (straight line 82) connecting the initial positions 68 of the guide objects 56.

  Further, the distance between the initial position 68 of the guide object 56 and the position of the character object 52 is set to a predetermined distance D. For this reason, the character object 52 is positioned at the midpoint of a straight line connecting the initial positions 68 of the two guide objects 56.

  Further, the guide object 56 is arranged so that the front direction 86 of the guide object 56 is parallel to the front direction 84 of the character object 52.

  After the guide object 56 is placed at the initial position 68, the guide unit 72 moves the guide object 56 toward the character object 52 at a constant speed so that the guide object 56 reaches the character object 52 at the reference timing.

  That is, as the reference timing approaches, the guide unit 72 moves the guide object 56 so that the guide object 56 approaches the character object 52. That is, as the time until the reference timing arrives, the guide unit 72 moves the guide object 56 such that the distance between the guide object 56 and the character object 52 is shortened. In short, the guide unit 72 sets the position of the guide object 56 over time so that the distance between the current position of the guide object 56 and the character object 52 becomes a distance corresponding to the time until the reference timing arrives. It will be updated accordingly.

  In the case of this embodiment, the guide unit 72 moves the guide object 56 on the straight line 82 toward the character object 52. In addition, the movement path | route in case the guidance object 56 moves toward the character object 52 does not need to be a straight line. For example, the moving path of the guide object 56 may be a curve.

  In the present embodiment, since the orientation of the guidance object 56 is the orientation of the character object 52 at the reference timing, when the guidance object 56 reaches the character object 52 at the reference timing, the guidance object 56 is Match exactly. In addition, after the guide object 56 reaches the character object 52 (that is, after the guide object 56 matches the character object 52), the guide unit 72 removes the guide object 56 from the virtual space 60.

  Next, the attitude data acquisition unit 74 will be described. The posture data acquisition unit 74 acquires posture data related to the posture that the player P actually takes. In the case of the present embodiment, the posture data acquisition unit 74 acquires the posture data supplied from the player detection unit 40.

  Next, the evaluation unit 76 will be described. The evaluation unit 76 evaluates the game play of the player P based on the reference data and the attitude data.

  For example, the evaluation unit 76 compares the model posture at the reference timing with the posture of the player P indicated by the posture data acquired at the target timing set based on the reference timing.

  The “target timing” is the reference timing itself. Here, the “target timing” will be described as the reference timing itself. However, as will be described below, the “target timing” is not limited to the reference timing.

  For example, the “target timing” may be a timing after a predetermined time from the reference timing. For example, when the processing load on the player detection unit 40 is relatively large, timing at which the player P actually takes a certain posture X and posture data indicating that the player P has taken the posture X are obtained from the player detection unit 40. The time (delay time) between the timing supplied to the control unit 14 may be relatively long. In such a case, in consideration of the delay time, a timing after a predetermined time (estimated delay time) from the reference timing may be set as the “target timing”. Thus, the model posture at the reference timing may be compared with the posture of the player P indicated by the posture data acquired by the posture data acquisition unit 74 at the target timing after a predetermined time from the reference timing. Good.

  Alternatively, the “target timing” may be a timing within a target period including a reference timing. For example, the “target timing” may be a timing within a target period from a time point before the reference timing to a time point after the reference timing. In this way, the model posture at the reference timing may be compared with the posture actually taken by the player P within the target period. In other words, the player P may take the model posture at the reference timing at any timing within the target period.

  The evaluation unit 76 determines the evaluation of the game play of the player P based on the similarity between the model posture at the reference timing and the posture of the player P indicated by the posture data acquired at the target timing. For example, when the degree of similarity is high, the player P's evaluation on the game play is higher than when the degree of similarity is low.

  The similarity between the posture of the player P and the model posture is determined by the position of each part of the player P (for example, the head P1, the left wrist P2, the right wrist P3, the waist P4, the left ankle P5, the right ankle P6). It is obtained by comparing the position of each part in the model posture. Details will be described later (see steps S109 and S110 in FIG. 16).

  Next, processing executed by the game apparatus 10 for realizing the above functional blocks will be described. 15 and 16 are flowcharts showing an example of processing related to the present invention among the processing executed by the game apparatus 10 from the start to the end of the game. The control unit 14 executes the processing shown in FIGS. 15 and 16 according to the program read from the optical disk 38, so that the control unit 14 functions as the guide unit 72, the posture data acquisition unit 74, and the evaluation unit 76. become.

  As shown in FIG. 15, the control unit 14 first displays the game screen in the initial state on the display unit 34 (S101). For example, the control unit 14 sets the posture of the character object 52 arranged in the virtual space 60 to a predetermined initial posture (for example, an upright posture). Then, the control unit 14 generates a game screen representing the virtual space 60 viewed from the virtual camera 64 and displays the game screen on the display unit 34. In this case, the guide object 56 is not arranged in the virtual space 60 except when the reference timing arrives within a period within a predetermined time (for example, a time corresponding to n bars of the music) from the music reproduction start timing.

  Next, the control unit 14 starts playing the music (S102). That is, the control unit 14 reads the music data from the optical disk 38 and starts reproducing the music data. As a result, output of the music from the audio output unit 36 is started.

  Next, the control unit 14 repeatedly executes the processes of steps S103 to S113 every predetermined time (frame rate: for example, 1/60 seconds). The processes in steps S103 to S113 include a process for updating the game screen and a process for evaluating the game play of the player P.

  First, the control unit 14 updates the posture of the character object 52 based on the motion data (S103). That is, the control unit 14 sets the posture of the character object 52 to the posture in the current frame indicated by the motion data. For example, the control unit 14 updates the skeleton state of the character object 52 to the state in the current frame indicated by the motion data.

  Thereafter, the control unit 14 determines whether or not the time until the reference timing has reached a predetermined time (S104). For example, the “predetermined time” is a time corresponding to n bars (for example, one bar) of the music to be played back, and in step S104, the control unit 14 determines whether the current time point is n bars before the reference timing. Determine whether or not. When the current time is a time point n measures before the reference timing, the control unit 14 determines that the time until the reference timing has arrived has reached a predetermined time.

  When it is determined that the time until the reference timing has reached the predetermined time, the control unit 14 (guide unit 72) places the guide object 56 at the initial position 68 in the virtual space 60 (S105). The control unit 14 arranges the two guide objects 56 at the initial position 68 as described with reference to FIG.

  In this case, model data of the character object 52 is used as model data of the guidance object 56. Further, the posture of the guidance object 56 is set based on the motion data of the character object 52. That is, the posture of the guide object 56 is set to the posture of the character object 52 at the reference timing indicated by the motion data of the character object 52. Specifically, the state of the skeleton of the character object 52 at the reference timing is acquired from the motion data of the character object 52. Then, the state of the skeleton of the guide object 56 is set to the state acquired from the motion data. In this way, the posture of the guidance object 56 is set to the posture of the character object 52 at the reference timing. Note that the color of the guidance object 56 is set to a predetermined color (for example, green).

  If it is not determined in step S104 that the time until the reference timing has reached a predetermined time, or if the process of step S105 is executed, the control unit 14 places the guidance object 56 in the virtual space 60. It is determined whether or not (S106).

  When the guidance object 56 is arranged in the virtual space 60, the control unit 14 updates the position of the guidance object 56 (S107). That is, the control unit 14 moves the guide object 56 toward the character object 52. For example, the control unit 14 updates the position of the guide object 56 to “a position moved from the current position of the guide object 56 to the position of the character object 52 by a predetermined movement distance from the current position of the guide object 56”. To do.

  The “predetermined movement distance” is set to such a movement distance that the guide object 56 reaches the character object 52 at the reference timing. For example, the “predetermined moving distance” is the distance between the initial position 68 of the guide object 56 and the position of the character object 52 (predetermined distance D in FIG. 14) for the predetermined time in step S104 (for example, n measures of music). The distance obtained by dividing by the time corresponding to.

  In step S107, the position of the guide object 56 disposed at the initial position 68 in the current frame is not updated.

  If it is determined in step S106 that the guidance object 56 is not arranged in the virtual space 60, or if the process of step S107 is executed, the control unit 14 determines whether or not the reference timing has arrived, as shown in FIG. Is determined (S108).

  When it is determined that the reference timing has arrived, the control unit 14 compares the posture of the player P with the model posture (S109). For example, the control unit 14 (attitude data acquisition unit 74) acquires the attitude data supplied from the player detection unit 40. Further, the control unit 14 acquires model posture data associated with the reference timing from the reference data (FIG. 13). Then, the control unit 14 (evaluation unit 76) compares the posture of the player P indicated by the posture data with the model posture indicated by the model posture data.

  For example, the control unit 14 calculates the similarity between the posture of the player P and the model posture. That is, the control unit 14 indicates the posture data indicated by the posture data for each of a plurality of representative parts of the player P (for example, the head P1, the left wrist P2, the right wrist P3, the waist P4, the left ankle P5, and the right ankle P6). The similarity is calculated by comparing the position of the part and the position of the part indicated by the model posture data.

  More specifically, for each of a plurality of representative parts, the control unit 14 has a distance between the position of the part indicated by the posture data and the position of the part indicated by the exemplary posture data is less than the reference distance. It is determined whether or not. Then, the control unit 14 calculates the similarity based on the number of parts determined that the distance is less than the reference distance. For example, the number of parts determined that the distance is less than the reference distance is acquired as the similarity. Note that the method of calculating the similarity between the posture of the player P and the model posture is not limited to the method described here, and other methods may be used.

  After the process of step S109 is executed, the control unit 14 (evaluation unit 76) updates the score of the player P based on the comparison result in step S109 (S110). For example, when the degree of similarity acquired in step P109 is higher than the reference value, the score of the player P is increased. Further, the score of the player P may be reduced when the similarity acquired in step P109 is lower than the reference value.

  After the process of step S110 is executed, the control unit 14 removes the guide object 56 from the virtual space 60 (S111). The case where the process of step S111 is executed is a case where the reference timing has arrived. In this case, the guide object 56 has reached the position of the character object 52. In step S111, the guide object 56 that has reached the position of the character object 52 is removed from the virtual space 60.

  When the process of step S111 is executed, or when it is not determined that the reference timing has arrived in step S108, the control unit 14 (guide unit 72) updates the game screen (S112). That is, the control unit 14 generates a game screen representing the virtual space 60 viewed from the virtual camera 64 and displays the game screen on the display unit 34.

  After the process of step S112 is executed, the control unit 14 determines whether or not the game end condition is satisfied (S113). The “game end condition” is, for example, a condition as to whether or not the reproduction of music has been completed. That is, when the reproduction of the music is completed, the control unit 14 determines that the game end condition is satisfied. The “game end condition” is not limited to the above conditions. The “game end condition” may be, for example, a condition indicating whether or not the score of the player P is less than a reference point.

  If it is not determined that the game end condition is satisfied, the control unit 14 re-executes the processes of steps S103 to S113. Until it is determined that the game end condition is satisfied, the processes in steps S103 to S113 are repeatedly executed at predetermined time intervals (frame rate: 1/60 seconds, for example).

  On the other hand, when it is determined that the game end condition is satisfied, the control unit 14 displays a result screen on the display unit 34 (S114). The result screen is a screen showing the game play result of the player P, and the score (game result) of the player P is displayed on the result screen. Then, after the result screen is displayed, this process ends and the game ends.

  In the game apparatus 10 described above, the guide object 56 having a posture corresponding to the model posture that the player P should take at the reference timing is displayed on the game screen. Further, the guide object 56 moves toward the character object 52 and reaches the character object 52 at the reference timing. As a result, the player P can relatively easily grasp both the reference timing and the model posture that the player P should take at the reference timing, relying on the guidance object 56 displayed on the game screen. According to the game apparatus 10, it is possible to make it possible for the player P to relatively easily grasp both the reference timing and the model posture that the player P should take at the reference timing.

  In the game apparatus 10, a state where the guidance object 56 arranged in the virtual space 60 is viewed from the virtual camera 64 is displayed on the game screen. Further, in the virtual space 60, the guide object 56 is arranged on the left side or the right side of the character object 52 that is the target of the virtual camera 64 when viewed from the virtual camera 64. For this reason, a state in which the guide object 56 is viewed from the front oblique direction of the guide object 56 is displayed on the game screen.

  As a result, the player P can easily grasp the model posture that the player P should take at the reference timing. For example, when only the state where the guidance object 56 is viewed from the front is displayed on the game screen, the player P can grasp the orientation of the guidance object 56 only in a plane. Therefore, for example, it is difficult for the player P to grasp that the guide object 56 moves the arm or the like forward (in the negative direction of the Zw axis). In this regard, when a state in which the guide object 56 is viewed from the front oblique direction of the guide object 56 is displayed on the game screen, since the displacement in the Zw-axis direction is expressed, the player P determines the orientation of the guide object 56 in three dimensions. It becomes easy to grasp. According to the game apparatus 10, it is possible to make it possible for the player P to easily grasp the model posture that the player P should take at the reference timing.

  In the game apparatus 10, one guide object 56 is disposed on the left side of the character object 52 when viewed from the virtual camera 64, and the other guide object 56 is disposed on the right side of the character object 52 when viewed from the virtual camera 64. The For this reason, both the state where the guide object 56 is viewed from the front right diagonal direction of the guide object 56 and the state where the guide object 56 is viewed from the front left diagonal direction of the guide object 56 are displayed on the game screen. As a result, the player P can easily grasp the orientation of the guidance object 56 in a three-dimensional manner. According to the game apparatus 10, it is possible to make it possible for the player P to easily grasp the model posture that the player P should take at the reference timing.

  The present invention is not limited to the embodiment described above.

  (A) In the above description, it has been described that the positional relationship between the character object 52 (reference position 67) and the virtual camera 64 is fixed. However, the positional relationship between the character object 52 (reference position 67) and the virtual camera 64 is as follows. It may be changed.

  In addition, when the positional relationship between the character object 52 and the virtual camera 64 changes, the guiding unit 72 may change the position of the guiding object 56 based on the positional relationship between the character object 52 and the virtual camera 64. Good.

  FIG. 17 is a diagram for describing an example of position control of the guide object 56 when the positional relationship between the character object 52 and the virtual camera 64 changes. FIG. 17 shows a case where the positional relationship between the character object 52 and the virtual camera 64 changes as the virtual camera 64 moves. In FIG. 17, reference numeral 64 a indicates a position before change of the virtual camera 64, and reference numeral 64 b indicates a position after change of the virtual camera 64. Reference numerals 56a and 56b indicate the position of the guide object 56 before the position of the virtual camera 64 changes, and reference numerals 56c and 56d indicate the position of the guide object 56 after the position of the virtual camera 64 changes. Yes.

  In the example shown in FIG. 17, the position of the virtual camera 64 is changed from the position 64a to the position 64b. The position 64b is a position that is rotated counterclockwise by an angle θ from the position 64a with the position of the character object 52 as the center. The line-of-sight direction 66b of the virtual camera 64 at the position 64b is set in the direction from the virtual camera 64 to the character object 52, similarly to the line-of-sight direction 66a of the virtual camera 64 at the position 64a. That is, the gaze target of the virtual camera 64 is set to the character object 52.

  When the position of the virtual camera 64 changes as described above, the guide unit 72 changes the position of one guide object 56 from the position 56a to the position 56c. Note that the position 56c is a position that is rotated counterclockwise by an angle θ from the position 56a with the position of the character object 52 as the center. In addition, the guide unit 72 changes the position of the other guide object 56 from the position 56b to the position 56d. The position 56d is a position obtained by rotating counterclockwise about the position of the character object 52 by an angle θ from the position 56b.

  The guide unit 72 sets the front directions 86c and 86d of the guide object 56 at the positions 56c and 56d in a direction parallel to the front direction 84 of the character object 52. In other words, the guide unit 72 sets the front directions 86c and 86d of the guide object 56 at the positions 56c and 56d to be parallel to the front directions 86a and 86b of the guide object 56 at the positions 56a and 56b.

  In this way, even if the positional relationship between the character object 52 (reference position 67) and the virtual camera 64 changes, both the reference timing and the model posture that the player P should take at the reference timing are displayed. It becomes possible for the player P to be able to grasp relatively easily.

  (B) A state where the character object 52 is viewed from behind may be displayed on the game screen. In this case, it is not necessary for the character object 52 to perform a dance (exemplary action) that the player P should perform in reverse. For this reason, the character object 52 should just perform the dance which the player P should perform.

  (C) The number of guide objects 56 arranged in the virtual space 60 may not be two. For example, three or more guide objects 56 may be arranged in the virtual space 60.

  Further, for example, only the integral guide object 56 may be arranged in the virtual space 60. That is, any one of the guide objects 56 may be removed from the virtual space 60 shown in FIG. In this case, instead of the guide object 56 moving toward the character object 52, the character object 52 may move toward the guide object 56. Alternatively, both the guide object 56 and the character object 52 may move toward each other. In either case, if the character object 52 and the guide object 56 overlap at the reference timing, the player P can recognize the arrival of the reference timing.

  (D) The present invention can also be applied to a game other than a game in which the player P aims to dance according to music. The present invention can be applied to a game in which the player P aims to take a predetermined model posture at a predetermined timing.
