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 the external interface 32 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. The control unit 14 can also grasp the movement of the player P's body by grasping the change in the posture of the player P (change in 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, the game device 10 executes a dance game in which the player P dances according to music.
FIG. 9 shows an example of a game screen displayed on the display unit 34. On the game screen shown in FIG. 9, a score 50 of the player P and a character object 52 representing a dancer are displayed.
The character object 52 serves to guide the player P about the dance that the player P should perform. In the game screen shown in FIG. 9, since the character object 52 is displayed so as to face the player P, the character object 52 dances the dance that the player P should dance to the left and right.
The player P aims to dance while watching the character object 52 in the same manner as the dance in which the character object 52 dances. 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 is the same. Move your right hand to the right. 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.
It should be noted that a state of the character object 52 viewed from behind may be displayed on the game screen. In this case, it is not necessary for the character object 52 to dance the dance that the player P should dance in reverse. For this reason, the character object 52 should just dance the dance which the player P should dance.
In this game, an evaluation timing (reference timing) for evaluating the dance of the player P is provided. The posture that the player P has taken at the evaluation timing is compared with the posture (exemplary posture) that the player P should take at the evaluation timing, and the dance of the player P is evaluated based on the comparison result. When the degree of similarity between the posture of the player P and the model posture is high, the player P's evaluation on the dance is high.
FIG. 10 shows an example of a game screen that is displayed when the evaluation timing approaches. Two guide 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 arrival of the evaluation timing and the model posture that the player P should take at the evaluation timing.
The guidance object 56 is displayed when the evaluation timing approaches. Specifically, when the remaining time until the evaluation timing has reached a predetermined time (for example, the time corresponding to two measures of the music), the two guide objects 56 are character objects as viewed from the player P. 52 on the left and right.
The guide object 56 is a silhouette of the character object 52 at the evaluation timing, and represents the posture that the character object 52 takes at the evaluation timing. The guide object 56 moves toward the character object 52 after being displayed at the initial position. At the evaluation timing, the guide object 56 reaches the character object 52 and overlaps the character object 52. The guidance object 56 disappears from the game screen after overlapping the character object 52.
For example, in the case of the example shown in FIG. 10, when the player P raises both hands up in the same manner as the guidance object 56 shown in FIG. 10 at the timing (evaluation timing) when the guidance object 56 overlaps the character object 52, The player P can obtain a good evaluation. The game apparatus 10 displays the guidance object 56 as described above so that the player P can grasp the arrival of the evaluation timing and the model posture that the player P should take at the evaluation timing.
Note that the evaluation timing may be provided continuously over a given period (see FIG. 16). Hereinafter, a period in which the evaluation timing is continuously provided is referred to as an “evaluation period”. The action (posture change) performed by the player P in the evaluation period is compared with the model action (model postural change) to be performed by the player P in the evaluation period, and the dance of the player P is evaluated based on the comparison result. For example, when the similarity between the action of the player P and the model action is high, the evaluation of the player P for the dance is high.
FIG. 11 shows an example of a game screen displayed when the evaluation period is approaching. A guidance object 58 is displayed on the game screen shown in FIG. The guidance object 58 plays a role of guiding (notifying) the player P of the arrival of the evaluation period and the model action that the player P should perform during the evaluation period.
The guidance object 58 is displayed when the evaluation period is approaching. Specifically, the guidance object 58 is displayed when the remaining time until the evaluation period has reached a predetermined time (for example, the time corresponding to two measures of music).
The guide object 58 indicates the movement path of the part when the character object 52 moves the part (for example, the left hand 54l). A guide object 58 shown in FIG. 11 indicates the movement path of the left hand 54l of the character object 52. The movement of the left hand 54l in this case is as follows: "The left hand 54l is raised to the head in an arc just beside the body, and then the left hand 54l is lowered to the vicinity of the right hand 54r in the same arc." is there.
For example, in the example shown in FIG. 11, when the evaluation period comes, the color of the guide object 58 gradually changes from the start end to the end so as to synchronize with the movement of the left hand 54l of the character object 52. When the evaluation period ends (that is, when the character object 52 finishes moving the left hand 54l along the movement path indicated by the guide object 58), the guide object 58 disappears from the game screen. When the player P moves the right hand in the same manner as the left hand 54l of the character object 52 relying on the guide object 58, the player P can obtain a good evaluation. In the game apparatus 10, the guidance object 58 as described above is displayed so that the player P can grasp the arrival of the evaluation period and the model action that the player P should perform in the evaluation period.
In the game apparatus 10, a virtual space is constructed in the main memory 16 in order to generate a game screen. FIG. 12 is a diagram illustrating an example of a virtual space. A virtual space 60 shown in FIG. 12 is a virtual three-dimensional space in which three coordinate axes (Xw, Yw, Zw axes) orthogonal to each other are set. The state of the virtual space 60 shown in FIG. 12 corresponds to the game screen shown in FIG.
As shown in FIG. 12, a floor object 62 representing a floor is arranged in the virtual space 60. In addition, the character object 52 is placed on the floor object 62. Further, a virtual camera 64 (viewpoint) is set in the virtual space 60. A 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 present embodiment, the character object 52 dances at substantially the same position, and the position of the virtual camera 64, the line-of-sight direction 66, and the angle of view are also fixed.
Although omitted in FIG. 12, guide objects 56 and 58 may be arranged in the virtual space 60. For example, when the game screen shown in FIG. 10 is displayed, the guidance object 56 is arranged in the virtual space 60. For example, when the game screen shown in FIG. 11 is displayed, the guidance object 58 is arranged in the virtual space 60.
Hereinafter, a technique for realizing a support function that supports the player P so that the player P can grasp in detail the drawbacks of his / her dance in the above dance game will be described.
FIG. 13 is a diagram for explaining the above-described support function, and shows an example of the game screen. The game screen shown in FIG. 13 indicates that the player P is not dancing to the rhythm, specifically, that the player P's dance is delayed from the music (that is, the player P has a part such as a hand or a foot). A message 70 indicating that the timing for moving is delayed) is displayed. This message 70 is displayed when it is determined that the dance of the player P is behind the music. By displaying the message 70, the player P can grasp that the dance is delayed from the music (that is, the timing of moving the hands, feet, etc. is delayed).
Note that when the dance of the player P precedes the music (that is, when the player P moves the parts such as hands and feet earlier), a message indicating that is displayed on the game screen.
FIG. 14 is also a diagram for explaining the above-described support function, and shows an example of a game screen. On the game screen shown in FIG. 14, a message 72 indicating that the player P is dancing in the opposite direction is displayed. This message 72 is displayed when it is determined that the player P is dancing in the opposite direction. For example, the message 72 is displayed when the player P raises the right hand even though the left hand should be raised. By displaying this message 72, it is possible for the player P to grasp that the dance is being performed in the opposite direction.
FIG. 15 is a functional block diagram mainly showing functional blocks related to the above-described support function among the functional blocks realized by the game apparatus 10. As shown in FIG. 15, the game apparatus 10 includes a storage unit 80, a posture data acquisition unit 82, a first comparison unit 84, a second comparison unit 86, and an output control unit 88.
The storage unit 80 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 80 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 80 are realized, for example, when the control unit 14 executes a program read from the optical disc 38.
First, the storage unit 80 will be described. The storage unit 80 stores various data necessary for executing the game.
For example, the storage unit 80 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 80 stores model data indicating the shape of the character object 52. Note that the model data of the character object 52 is also used as model data of the guidance object 56. The storage unit 80 also stores model data of the guidance object 58.
Further, for example, the storage unit 80 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. 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 present embodiment, motion data for causing the character object 52 to perform an action corresponding to the action to be performed by the player P is stored in the storage unit 80. Specifically, motion data for causing the character object 52 to perform a dance that the player P should dance in the left-right direction is stored in the storage unit 80. In this motion data, a change in the posture of the character object 52 while the music is being played is defined. By reproducing the motion data in synchronism with the reproduction of the music, the character object 52 dances the dance that the player P should dance in reverse to the music.
For example, the memory | storage part 80 memorize | stores the data regarding evaluation timing (evaluation period). Further, the storage unit 80 stores data related to the model posture that the player P should take at the evaluation timing (model action that the player P should perform during the evaluation period).
FIG. 16 shows an example of model data stored in the storage unit 80. The model data shown in FIG. 16 is data indicating the evaluation timing and the model posture that the player P should take. In FIG. 16, the t-axis is a time axis and indicates the passage of time since the reproduction of music was started.
In the model data, for example, the evaluation timing is shown in units of 1/256 measures of music. However, in the model data shown in FIG. 16, for the sake of convenience, the evaluation timing is shown in units of 1/8 bar of music. In the exemplary data shown in FIG. 16, whether each timing is an evaluation timing is indicated by 1-bit data. “0” indicates that the timing is not the evaluation timing, and “1” indicates that the timing is the evaluation timing.
In the model data shown in FIG. 16, model posture data is associated with each timing. This model posture data is data indicating the model posture that the player P should take at the 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.). The position of each part is expressed as a coordinate value in the XeYeZe coordinate system, for example, similarly to the posture data shown in FIG.
In the exemplary data shown in FIG. 16, the period in which the evaluation timing is continuous corresponds to the evaluation period. The exemplary posture data group associated with each timing within the evaluation period indicates an exemplary posture change of the player P during the evaluation period, that is, exemplary actions that the player P should perform during the evaluation period.
Note that the evaluation timing may be indicated by using an elapsed time from the start of music reproduction (or game execution). Alternatively, the evaluation timing may be indicated by using the data amount of the reproduced music data. For example, the timing when the data amount of the reproduced music data becomes D1, D2, D3,... Bytes (D1, D2, D3: numerical values) may be set as the evaluation timing.
For example, the storage unit 80 stores game situation data indicating the current situation of the game. For example, the following information is included in the game situation data.
-Music playback position information (information indicating what measure of the music is currently playing)
-Reproduction position information of the motion data of the character object 52 (information indicating which frame of the motion data is currently reproduced)
-State information (for example, position) of the character object 52
-State information of the guidance objects 56 and 58 (for example, position)
State information of the virtual camera 64 (for example, position, line-of-sight direction 66, angle of view, etc.)
・ Score information of player P
Next, the attitude data acquisition unit 82 will be described. The posture data acquisition unit 82 acquires posture data related to the posture that the player P has actually taken. In the case of the present embodiment, the posture data acquisition unit 82 acquires the posture data supplied from the player detection unit 40.
Next, the first comparison unit 84 will be described. The first comparison unit 84 has a model posture to be taken by the player P at the evaluation timing, the posture of the player P indicated by the posture data acquired by the posture data acquisition unit 82 at the comparison target timing set based on the evaluation timing, Is compared, and the comparison between the posture of the player P and the model posture is executed.
The “comparison target timing” is, for example, the evaluation timing itself. The following description will be made on the assumption that the “comparison target timing” is the evaluation timing itself.
However, the “comparison target timing” is not limited to the evaluation timing. For example, the “comparison target timing” may be a timing later than the evaluation 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 evaluation timing may be set as the “comparison target timing”.
For example, the first comparison unit 84 calculates the similarity between the model posture that the player P should take at the evaluation timing and the posture of the player P indicated by the posture data acquired at the evaluation timing (comparison target timing). Details will be described later (see step S111 in FIG. 22).
Further, for example, the first comparison unit 84 is based on the similarity between the model posture that the player P should take at the evaluation timing and the posture of the player P indicated by the posture data acquired at the evaluation timing (comparison target timing). The similarity between the exemplary action that the player P should perform in the evaluation period including the evaluation timing and the action performed by the player P in the comparison target period set based on the evaluation period is calculated. Details will be described later (see step S120 in FIG. 23).
The “comparison target period” is, for example, the evaluation period itself. The following description will be made on the assumption that the “comparison period” is the evaluation period itself. However, like the above-described relationship between the “evaluation timing” and the “comparison target timing”, the “comparison target period” is not limited to the evaluation period. For example, the “comparison target period” is a period in which the evaluation period is shifted in the future direction (that is, a timing after a predetermined time after the start timing of the evaluation period is set as a start timing and a predetermined time after the end timing of the evaluation period) It may be a period in which the timing is the end timing).
Next, the second comparison unit 86 and the output control unit 88 will be described.
The second comparison unit 86 performs a comparison between the posture of the player P and the model posture by changing one of “the posture of the player P” and “the model posture” that are the targets of comparison by the first comparison unit 84.
For example, the second comparison unit 86 compares the posture different from the model posture that the player P should take at the evaluation timing and the posture of the player P indicated by the posture data acquired at the comparison target timing.
Here, the “posture different from the exemplary posture to be taken by the player P at the evaluation timing” is, for example, the exemplary posture that the player P should take at a timing before or after the evaluation timing. Alternatively, the “posture different from the model posture that the player P should take at the evaluation timing” is, for example, a posture obtained by making a predetermined change to the model posture that the player P should take at the evaluation timing. The “posture obtained by making a predetermined change to the model posture to be taken by the player P at the evaluation timing” is, for example, a posture obtained by horizontally flipping the model posture to be taken by the player P at the evaluation timing. is there.
Further, for example, the second comparison unit 86 performs a comparison between the model posture that the player P should take at the evaluation timing and a posture different from the posture of the player P indicated by the posture data acquired at the comparison target timing. Also good.
Here, the “posture different from the posture of the player P indicated by the posture data acquired at the comparison target timing” refers to, for example, the player P indicated by the posture data acquired at a timing before or after the comparison target timing. It is posture. Alternatively, “an attitude different from the attitude of the player P indicated by the attitude data acquired at the comparison target timing” refers to, for example, a predetermined change with respect to the attitude of the player P indicated by the attitude data acquired at the comparison target timing. It is a posture obtained by applying. The “posture obtained by making a predetermined change to the posture of the player P indicated by the posture data acquired at the comparison target timing” is, for example, the player P indicated by the posture data acquired at the comparison target timing. It is a posture formed by reversing the posture of left and right.
The output control unit 88 causes the output unit to output based on the comparison between the comparison result of the first comparison unit 84 and the comparison result of the second comparison unit 86. The “output means” is, for example, the display unit 34 or the audio output unit 36, and the “output” includes, for example, display output or audio output.
In the case of this embodiment, the output control unit 88 determines the dance defect of the player P by comparing the comparison result of the first comparison unit 84 with the comparison result of the second comparison unit 86. For example, the output control unit 88 determines the following.
Whether or not the dance of the player P is behind the music. Whether or not the dance of the player P precedes the music. Whether or not the player P is dancing the dance from left to right.
Then, the output control unit 88 causes the output means to output to notify the player P of the result. For example, the output control unit 88 displays a message indicating the above result on the game screen (see FIGS. 13 and 14).
Instead of displaying a message, the output control unit 88 may display an image on the game screen based on the above result. For example, the output control unit 88 may display an image (for example, an icon image) indicating the above result on the game screen, or may display an effect image on the game screen based on the above result. The output control unit 88 may change the display mode (for example, color) of the image (for example, the character object 52) displayed on the game screen based on the above result. Further, the output control unit 88 may output a sound from the sound output unit 36 based on the above result. For example, the output control unit 88 may cause the voice output unit 36 to output a voice message indicating the above result.
Hereinafter, operations of the second comparison unit 86 and the output control unit 88 will be described in more detail. Here, eight examples will be described.
First, the first example will be described. The first example is whether or not the player P is dancing to the rhythm (specifically, whether or not the dance of the player P is behind the music, and the dance of the player P precedes the music). It is an example of determining whether or not).
FIG. 17 is a diagram for explaining the first example. In FIG. 17, the t-axis is a time axis, and shows the passage of time since the reproduction of music was started (the same applies to FIGS. 18 to 20 described later). In FIG. 17, “Sa” indicates the similarity between the model posture that the player P should take at the evaluation timing Ta and the posture of the player P indicated by the posture data acquired at the evaluation timing Ta. A method for calculating the similarity Sa will be described later (see step S111 in FIG. 22). The similarity Sa is acquired by the first comparison unit 84.
The second comparison unit 86 in the first example includes the model posture that the player P should take at a timing Tb that is a predetermined time before the evaluation timing Ta, and the posture of the player P indicated by the posture data acquired at the evaluation timing Ta. Compare For example, the second comparison unit 86 calculates the similarity Sb between the model posture at the timing Tb and the posture of the player P at the evaluation timing Ta. A method for calculating the similarity Sb will be described later (see step S114 in FIG. 22).
The case where the similarity Sb is higher than the similarity Sa is a case where the posture of the player P at the evaluation timing Ta is more similar to the exemplary posture at the timing Tb than the exemplary posture at the evaluation timing Ta. Since the timing Tb is a timing prior to the evaluation timing Ta, in such a case, the dance is generally matched, but it can be considered that the movement of the player P is behind the music. Therefore, in such a case, the output control unit 88 displays a message indicating that the dance of the player P is behind the music on the game screen (see FIG. 13).
Further, the second comparison unit 86 compares the model posture that the player P should take at the timing Tc after a predetermined time from the evaluation timing Ta with the posture of the player P indicated by the posture data acquired at the evaluation timing Ta. For example, the second comparison unit 86 calculates the similarity Sc between the model posture at the timing Tc and the posture of the player P at the evaluation timing Ta.
The case where the similarity Sc is higher than the similarity Sa is a case where the posture of the player P at the evaluation timing Ta is more similar to the exemplary posture at the timing Tc than the exemplary posture at the evaluation timing Ta. Since the timing Tc is a timing later than the evaluation timing Ta, in such a case, although the dance is generally matched, it can be considered that the movement of the player P precedes the music. In such a case, the output control unit 88 displays a message on the game screen indicating that the dance of the player P precedes the music.
A second example will be described. Similarly to the first example, the second example is an example of determining whether the dance of the player P is behind the music or whether the dance of the player P is ahead of the music. ing. However, the second example is different from the first example in that the posture of the player P at the timing before or after the evaluation timing is considered instead of the model posture at the timing before or after the evaluation timing. Is different.
FIG. 18 is a diagram for explaining the second example. As in FIG. 17, “Sa” indicates the similarity between the model posture that the player P should take at the evaluation timing Ta and the posture of the player P indicated by the posture data acquired at the evaluation timing Ta. This similarity Sa is acquired by the first comparison unit 84.
The second comparison unit 86 in the second example includes the model posture that the player P should take at the evaluation timing Ta, and the posture of the player P indicated by the posture data acquired at a timing Tb a predetermined time before the evaluation timing Ta. Compare For example, the second comparison unit 86 calculates the similarity Sb between the model posture at the evaluation timing Ta and the posture of the player P at the timing Tb. A method for calculating the similarity Sb will be described later (see step S115 in FIG. 22).
The case where the similarity Sb is higher than the similarity Sa is a case where the model posture at the evaluation timing Ta is more similar to the posture of the player P at the timing Tb than the posture of the player P at the evaluation timing Ta. . Since the evaluation timing Ta is a timing later than the timing Tb, in such a case, the dance is generally matched, but it can be considered that the movement of the player P precedes the music. In such a case, the output control unit 88 displays a message on the game screen indicating that the dance of the player P precedes the music.
Further, the second comparison unit 86 compares the model posture that the player P should take at the evaluation timing Ta with the posture of the player P indicated by the posture data acquired at a timing Tc after a predetermined time from the evaluation timing Ta. For example, the second comparison unit 86 calculates the similarity Sc between the model posture at the evaluation timing Ta and the posture of the player P at the timing Tc.
The case where the similarity Sc is higher than the similarity Sa is a case where the model posture at the evaluation timing Ta is more similar to the posture of the player P at the timing Tc than the posture of the player P at the evaluation timing Ta. . Since the evaluation timing Ta is a timing before the timing Tc, in such a case, the dance is generally matched, but it can be considered that the movement of the player P is behind the music. Therefore, in such a case, the output control unit 88 displays a message indicating that the dance of the player P is behind the music on the game screen (see FIG. 13).
A third example will be described. In the third example, as in the first and second examples, it is determined whether or not the dance of the player P is behind the music, and whether or not the dance of the player P precedes the music. It is an example to do. However, the third example is different from the first and second examples in that the above determination is performed noting only one timing but focusing on a plurality of timings. Is different.
FIG. 19 is a diagram for explaining the third example. In FIG. 19, “Sa” indicates the similarity between the exemplary action that the player P should perform in the evaluation period La and the action performed by the player P in the evaluation period La.
The similarity Sa is obtained by comparing the model posture at each timing T2, T3, T4, T5 in the evaluation period La with the posture of the player P at each timing T2, T3, T4, T5 in the evaluation period La. To be acquired. A method for calculating the similarity Sa will be described later (see step S120 in FIG. 23). This similarity Sa is acquired by the first comparison unit 84.
In FIG. 19, a period Lb indicates a period obtained by shifting the evaluation period La in the past direction (t-axis negative direction). Note that the lengths of the evaluation period La and the period Lb are equal. The start timing T1 of the period Lb is a timing before the start timing T2 of the evaluation period La, and the end timing T4 of the period Lb is a timing before the end timing T5 of the evaluation period La.
The second comparison unit 86 in the third example compares an exemplary action to be performed by the player P in the period Lb with an action performed by the player P in the evaluation period La. For example, the second comparison unit 86 calculates the similarity Sb between the model action in the period Lb and the action of the player P in the evaluation period La.
The similarity Sb is obtained by comparing the model posture at each timing T1, T2, T3, T4 within the period Lb with the posture of the player P at each timing T2, T3, T4, T5 within the evaluation period La. Is done. A method of calculating the similarity Sb will be described later (see step S123 in FIG. 23).
The case where the similarity Sb is higher than the similarity Sa is a case where the action of the player P in the evaluation period La is more similar to the model action in the period Lb than the model action in the evaluation period La. Since the period Lb is a period before the evaluation period La, in such a case, the dance is generally suitable, but it can be considered that the movement of the player P is behind the music. Therefore, in such a case, the output control unit 88 displays a message indicating that the dance of the player P is behind the music on the game screen (see FIG. 13).
Similarly, the second comparison unit 86 performs an exemplary action to be performed by the player P in the period Lc (not shown) in which the evaluation period La is shifted in the future direction (t-axis positive direction), and the player P in the evaluation period La. The operation performed by may be compared. For example, the second comparison unit 86 may calculate the similarity Sc between the exemplary action in the period Lc and the action of the player P in the evaluation period La.
The case where the similarity Sc in this case is higher than the similarity Sa is a case where the action of the player P in the evaluation period La is more similar to the model action in the period Lc than the model action in the evaluation period La. . Since the period Lc is a period after the evaluation period La, in such a case, the dance is generally suitable, but it can be considered that the movement of the player P precedes the music. Therefore, in such a case, the output control unit 88 may display a message indicating that the dance of the player P precedes the music on the game screen.
A fourth example will be described. The fourth example is also an example in which it is determined whether or not the dance of the player P is behind the music, and whether or not the dance of the player P precedes the music. The fourth example is similar to the third example in that the above determination is performed noting only one timing but focusing on a plurality of timings. However, in the fourth example, in consideration of the posture (motion) of the player P at the timing before or after the evaluation period, not the model posture (model motion) at the timing before or after the evaluation timing. It differs from the third example.
FIG. 20 is a diagram for explaining the fourth example. As in FIG. 19, “Sa” indicates the similarity between the exemplary action that the player P should perform during the evaluation period La and the action performed by the player P during the evaluation period La. Similarly to FIG. 19, the period Lb indicates a period formed by shifting the evaluation period La in the past direction (t-axis negative direction).
The second comparison unit 86 in the fourth example compares the model action to be performed by the player P in the evaluation period La and the action performed by the player P in the period Lb. For example, the second comparison unit 86 calculates the similarity Sb between the model action in the evaluation period La and the action of the player P in the period Lb.
The similarity Sb is acquired by comparing the model posture at each timing T2, T3, T4, and T5 within the evaluation period La with the posture of the player P at each timing T1, T2, T3, and T4 within the period Lb. Is done. A method of calculating the similarity Sb will be described later (see step S124 in FIG. 23).
The case where the similarity Sb is higher than the similarity Sa is a case where the exemplary action in the evaluation period La is more similar to the action of the player P in the period Lb than the action of the player P in the evaluation period La. . Since the evaluation period La is a period after the period Lb, in such a case, the dance is generally suitable, but it can be considered that the movement of the player P precedes the music. In such a case, the output control unit 88 displays a message on the game screen indicating that the dance of the player P precedes the music.
Similarly, the second comparison unit 86 performs the exemplary action to be performed by the player P in the evaluation period La and the player P in the period Lc (not shown) in which the evaluation period La is shifted in the future direction (t-axis positive direction). The operation performed by may be compared. For example, the second comparison unit 86 may calculate the similarity Sc between the exemplary action in the evaluation period La and the action of the player P in the period Lc.
The case where the similarity Sc in this case is higher than the similarity Sa is a case where the exemplary action in the evaluation period La is more similar to the action of the player P in the period Lc than the action of the player P in the evaluation period La It is. Since the evaluation period La is a period before the period Lc, in such a case, the dance is generally matched, but it can be considered that the movement of the player P is behind the music. Therefore, in such a case, the output control unit 88 may display a message indicating that the dance of the player P is behind the music on the game screen (see FIG. 13).
A fifth example will be described. Unlike the first to fourth examples, the fifth example is an example in which it is determined whether or not the dance of the player P is reversed left and right.
The second comparison unit 86 in the fifth example is a posture obtained by changing the model posture that the player P should take at the evaluation timing, and the posture of the player P indicated by the posture data acquired at the evaluation timing (comparison target timing). And compare.
For example, the second comparison unit 86 calculates the similarity between the posture obtained by horizontally flipping the model posture that the player P should take at the evaluation timing and the posture of the player P indicated by the posture data acquired at the evaluation timing. A method of calculating the similarity will be described later (see step S116 in FIG. 22). In this case, a posture obtained by reversing the model posture left and right corresponds to a “posture obtained by changing the model posture”.
When the similarity is higher than the similarity calculated by the first comparison unit 84 (Sa in FIG. 17), the posture of the player P is reversed from the model posture to the left and right. This is a case similar to the posture. In this case, although it is dancing to music, it can be considered that the player P is dancing the dance in the opposite direction. Therefore, in such a case, the output control unit 88 displays a message on the game screen indicating that the player P is dancing in the opposite direction (see FIG. 14).
A sixth example will be described. Similarly to the fifth example, the sixth example is an example of determining whether or not the dance of the player P is reversed left and right. However, the sixth example is different from the fifth example in that the model posture is not reversed left and right, but the posture of the player P is reversed left and right.
The second comparison unit 86 in the sixth example is a posture formed by changing the model posture that the player P should take at the evaluation timing and the posture of the player P indicated by the posture data acquired at the evaluation timing (comparison target timing). And compare.
For example, the second comparison unit 86 calculates the similarity between the model posture that the player P should take at the evaluation timing and the posture obtained by horizontally inverting the posture of the player P indicated by the posture data acquired at the evaluation timing. In this case, the posture obtained by horizontally flipping the posture of the player P corresponds to the “posture obtained by changing the posture of the player P”.
When the similarity is higher than the similarity calculated by the first comparison unit 84 (Sa in FIG. 17), the model posture reverses the posture of the player P left and right rather than the posture of the player P. Is similar to the posture. In this case, although it is dancing to music, it can be considered that the player P is dancing the dance in the opposite direction. Therefore, in such a case, the output control unit 88 displays a message on the game screen indicating that the player P is dancing in the opposite direction (see FIG. 14).
A seventh example will be described. Similarly to the fifth and sixth examples, the seventh example is an example in which it is determined whether or not the dance of the player P is reversed left and right. However, the seventh example is different from the fifth and sixth examples in that the above determination is performed noting only one timing but focusing on a plurality of timings. Is different.
The second comparison unit 86 in the seventh example compares an action made by changing the model action to be performed by the player P during the evaluation period with an action performed by the player P during the evaluation period.
For example, the second comparison unit 86 calculates a similarity between an action obtained by reversing the model action in the evaluation period and the action of the player P in the evaluation period. A method for calculating the similarity will be described later (see step S125 in FIG. 23).
In this case, an operation obtained by reversing the model operation left and right corresponds to an “operation by changing the model operation”. An operation obtained by horizontally reversing the model operation in the evaluation period may be obtained, for example, by reversing the model posture at all timings in the evaluation period.
When the similarity is higher than the similarity calculated by the first comparison unit 84 (Sa in FIG. 17), the action of the player P is reversed from the model action to the left and right. This is a case similar to operation. In this case, although it is dancing to music, it can be considered that the player P is dancing the dance in the opposite direction. Therefore, in such a case, the output control unit 88 displays a message on the game screen indicating that the player P is dancing in the opposite direction (see FIG. 14).
An eighth example will be described. Similarly to the seventh example, the eighth example is an example of determining whether or not the dance of the player P is reversed left and right. However, the eighth example is different from the seventh example in that the model action is not horizontally reversed but the player P's action is horizontally reversed.
The second comparison unit 86 in the eighth example compares an exemplary action to be performed by the player P during the evaluation period with an action obtained by changing the action performed by the player P during the evaluation period.
For example, the second comparison unit 86 calculates the similarity between the model action in the evaluation period and the action obtained by horizontally inverting the action of the player P in the evaluation period. In this case, an action obtained by horizontally inverting the action of the player P corresponds to “an action obtained by changing the action of the player P”. For example, an operation obtained by reversing the motion of the player P during the evaluation period may be obtained by reversing the posture of the player P at all timings during the evaluation period.
The case where the similarity is higher than the similarity (Sa in FIG. 17) calculated by the first comparison unit 84 is that the exemplary action is performed by the player P more than the action actually performed by the player P. This is a case similar to an operation obtained by reversing the left and right operations. In this case, although it is dancing to music, it can be considered that the player P is dancing the dance in the opposite direction. Therefore, in such a case, the output control unit 88 displays a message on the game screen indicating that the player P is dancing in the opposite direction (see FIG. 14).
Next, a process executed by the game apparatus 10 in order to realize the above support function will be described. FIG. 21, FIG. 22, and FIG. 23 are flowcharts showing an example of processing related to the above-described support function among the processing executed by the game apparatus 10 from the start to the end of the game. . The control unit 14 executes the processes shown in FIGS. 21 to 23 according to the program read from the optical disc 38, so that the control unit 14 has the attitude data acquisition unit 82, the first comparison unit 84, the second comparison unit 86, and It functions as the output control unit 88.
As shown in FIG. 21, first, the control unit 14 displays an initial game screen on the display unit 34 (S101). On the game screen in the initial state, the posture of the character object 52 is set to a predetermined initial posture (for example, an upright posture).
Further, the control unit 14 starts playing the music (S102). Thereafter, the control unit 14 repeatedly executes the processes of steps S103 to S127 every predetermined time (frame rate: for example, 1/60 seconds).
First, the control unit 14 (posture data acquisition unit 82) acquires the posture data of the player P supplied from the player detection unit 40, and stores the posture data in the storage unit 80 (S103). The storage unit 80 stores a history of the posture data of the player P in time series.
Thereafter, the control unit 14 updates the posture of the character object 52 based on the motion data (S104). 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.
Thereafter, the control unit 14 determines whether or not the time until the single evaluation timing or the start timing of the evaluation period has reached a predetermined time (S105). “Single evaluation timing” means evaluation timing that is not continuous. The “predetermined time” is a time corresponding to, for example, n bars (for example, two bars) of the music.
When it is determined that the time until the single evaluation timing or the start timing of the evaluation period has reached a predetermined time, the control unit 14 places the guide objects 56 and 58 in the virtual space 60 (S106).
For example, when it is determined in step S <b> 105 that the time until the single evaluation timing has come is a predetermined time, the guide object 56 is placed in the virtual space 60. The posture of the guidance object 56 is set to the posture of the character object 52 at the evaluation timing based on the motion data of the character object 52. The guide object 56 is set to a predetermined color (for example, green) and translucent. On the other hand, if it is determined in step S105 that the time until the start timing of the evaluation period has reached a predetermined time, the guide object 58 is placed in the virtual space 60.
If it is not determined in step S105 that the time until the single evaluation timing or the start timing of the evaluation period has reached a predetermined time, or if the process of step S106 is executed, the control unit 14 performs the guidance object It is determined whether or not 56 and 58 are arranged in the virtual space 60 (S107). When the guide objects 56 and 58 are arranged in the virtual space 60, the control unit 14 updates the state of the guide objects 56 and 58 (S108).
For example, when the guide object 56 is arranged in the virtual space 60, the control unit 14 moves the guide object 56 toward the character object 52. The guide object 56 is controlled to reach the character object 52 at the evaluation timing.
On the other hand, when the guide object 58 is arranged in the virtual space 60, the control unit 14 changes the color of the guide object 58 from the start end to the end so as to synchronize with the movement of the part of the character object 52 within the evaluation period. The guide object 58 is controlled so as to gradually change.
When it is determined in step S107 that the guidance objects 56 and 58 are not arranged in the virtual space 60, or when the process of step S108 is executed, the control unit 14 determines whether or not a single evaluation timing has arrived. (S109). When it is determined that the single evaluation timing has arrived, as shown in FIG. 22, the control unit 14 (first comparison unit 84) determines the similarity between the current posture of the player P and the current exemplary posture. S1 is calculated (S111).
For example, the control unit 14 acquires model posture data corresponding to the current time from the model data. Then, the control unit 14 calculates the similarity between the posture data acquired in step S106 and the model posture data.
For example, the control unit 14 indicates the portion indicated by the posture data for each of a plurality of representative portions 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). It is determined whether the distance between this position and the position of the part indicated by the model posture data is less than the reference distance.
For example, when the representative part is “head P1, left wrist P2, right wrist P3, waist P4, left ankle P5, and right ankle P6”, the control unit 14 determines the position of the head P1 indicated by the posture data and the model posture. It is determined whether the distance from the position of the head P1 indicated by the data is less than the reference distance. The control unit 14 performs the same determination for the left wrist P2, the right wrist P3, the waist P4, the left ankle P5, or the right ankle P6.
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, when the total number of representative parts is M and the number of parts determined that the distance is less than the reference distance is m, the similarity S1 is calculated by the following equation (1).
S1 = m / M (1)
For example, the representative part is “head P1, left wrist P2, right wrist P3, waist P4, left ankle P5, and right ankle P6”, and the part where the above distance is determined to be less than the reference distance is “ In the case of “left wrist P2, waist P4, and right ankle P6”, 0.5 is calculated as the similarity S1. Note that the method of calculating the similarity S1 is not limited to the method described here. For example, the number (m) of parts determined as the distance being less than the reference distance may be acquired as the similarity S1.
After the process of step S111 is executed, the control unit 14 updates the score of the player P (S112), and removes the guide object 56 from the virtual space 60 (S113). In step S112, for example, the score of the player P is increased when the similarity S1 acquired in step S111 is higher than the reference value.
After the process of step S113 is executed, the control unit 14 (second comparison unit 86) calculates a similarity S2 between the posture of the player P at the current time and the model posture at a time point a predetermined time before the current time (S114). ). For example, the control unit 14 acquires model posture data corresponding to a time point before a predetermined time from the model data. Then, the control unit 14 calculates a similarity S <b> 2 between the posture data acquired in step S <b> 106 and the exemplary model posture data corresponding to a time point before a predetermined time. The similarity S2 is calculated by the same method as that used when the similarity S1 is calculated in step S111.
After the process of step S114 is executed, the control unit 14 (second comparison unit 86) calculates a similarity S3 between the posture of the player P at a time point a predetermined time before the current time and the model posture at the current time (S115). ). For example, the control unit 14 acquires attitude data acquired at a time point before a predetermined time from the storage unit 80. In addition, the control unit 14 acquires model posture data corresponding to the current time from the model data. And the control part 14 calculates the similarity S3 of these attitude | position data and model attitude | position data. The similarity S3 is calculated by the same method as when the similarity S1 is calculated in step S111.
After the processing of step S115 is executed, the control unit 14 (second comparison unit 86) calculates the similarity S4 between the posture of the player P at the current time and the posture obtained by horizontally inverting the model posture at the current time ( S116). For example, the control unit 14 acquires model posture data corresponding to the current time from the model data, and generates left-right reversed posture data indicating a posture obtained by horizontally flipping the model posture based on the model posture data. The control unit 14 calculates a similarity S4 between the posture data acquired in step S106 and the horizontally reversed posture data. The similarity S4 is calculated by the same method as that used when the similarity S1 is calculated in step S111.
After the process of step S116 is executed, the control unit 14 (output control unit 88) determines that the similarity S1 calculated in step S111 is any one of the similarities S2 to S4 calculated in steps S114 to S116. It is judged whether it is higher than (S117).
When it is determined that any one of the similarities S2 to S4 is higher than the similarity S1, the control unit 14 (output control unit 88) updates the game screen as described below (S118). For example, the control unit 14 generates an image representing the virtual space 60 viewed from the virtual camera 64 on the VRAM. Further, the control unit 14 draws the score 50 of the player P at a predetermined position of the image generated on the VRAM. Further, the control unit 14 draws a message based on the comparison result between the similarity S2 to S4 and the similarity S1 at a predetermined position of the image generated on the VRAM.
For example, when the similarity S2 is higher than the similarity S1, the control unit 14 determines that the dance of the player P is behind the music, and draws a message indicating that (for example, the message 70 in FIG. 13). . For example, when the similarity S3 is higher than the similarity S1, the control unit 14 determines that the dance of the player P precedes the music, and draws a message indicating that. Further, for example, when the similarity S4 is higher than the similarity S1, the control unit 14 determines that the dance of the player P is reversed left and right, and draws a message indicating that (for example, the message 72 in FIG. 14). To do.
The image generated on the VRAM as described above is displayed on the display unit 34 as a game screen. In this case, a message indicating the disadvantage of the dance of the player P is displayed on the game screen (see FIGS. 13 and 14). This message may be displayed on the game screen for a certain time.
By the way, when a plurality of similarities among the similarities S2 to S4 are higher than the similarities S1, it may be determined that the dance defect of the player P could not be specified and the message may not be drawn. Alternatively, a message corresponding to the highest similarity among the plurality of similarities may be drawn.
On the other hand, if it is determined in step S117 that none of the similarities S2 to S4 is higher than the similarity S1, the control unit 14 updates the game screen as described below (S119). For example, the control unit 14 generates an image representing the virtual space 60 viewed from the virtual camera 64 on the VRAM. Further, the control unit 14 draws the score 50 of the player P at a predetermined position of the image generated on the VRAM. The image thus generated on the VRAM is displayed on the display unit 34 as a game screen.
When it is determined in step S109 in FIG. 21 that the single evaluation timing has not arrived, the control unit 14 determines whether or not the end timing of the evaluation period has arrived (S110). When it is determined that the end timing of the evaluation period has not arrived, the control unit 14 updates the game screen (S119). Since the process in step S119 has already been described, the description thereof is omitted here.
On the other hand, when it is determined that the end timing of the evaluation period has arrived, as shown in FIG. 23, the control unit 14 (first comparison unit 84) performs the action of the player P in the evaluation period and the exemplary action in the evaluation period. The similarity S5 is calculated (S120).
Here, the process of step S120 will be described with reference to FIG. For example, the control unit 14 acquires posture data acquired at individual timings T2, T3, T4, and T5 within the evaluation period La from the storage unit 80. Further, the control unit 14 acquires model posture data corresponding to the individual timings T2, T3, T4, and T5 within the evaluation period La from the model data.
And the control part 14 calculates the similarity in each timing T2, T3, T4, T5 in the evaluation period La. For example, as the degree of similarity at the timing T2, the control unit 14 calculates the degree of similarity between the attitude data acquired at the timing T2 and the model attitude data corresponding to the timing T2. This similarity is calculated in the same way as when the similarity S1 is calculated in step S111. Similarly, the control unit 14 calculates the similarity at each of the timings T3, T4, and T5. And the control part 14 calculates the statistics (for example, average value) of the similarity in each timing T2, T3, T4, T5 in the evaluation period La, and acquires the statistics as said similarity S5.
After the process of step S120 is executed, the control unit 14 updates the score of the player P (S121), and removes the guide object 58 from the virtual space 60 (S122). In step S121, for example, when the similarity S5 acquired in step S120 is higher than the reference value, the score of the player P is increased.
After the process of step S122 is executed, the control unit 14 (second comparison unit 86) performs an operation performed by the player P in the evaluation period and a period in which the evaluation period is shifted in the past direction (past period: for example, FIG. 19 In the period Lb), the similarity S6 with the exemplary action to be performed by the player P is calculated (S123).
Again, the process of step S123 will be described with reference to FIG. For example, the control unit 14 acquires posture data acquired at individual timings T2, T3, T4, and T5 within the evaluation period La from the storage unit 80. Further, the control unit 14 acquires model posture data corresponding to individual timings T1, T2, T3, T4, and T5 within the period Lb (past period) from the model data.
And the control part 14 calculates the similarity regarding each timing T2, T3, T4, and T5 in the evaluation period La. For example, as the similarity with respect to the timing T2, the control unit 14 calculates the similarity between the posture data acquired at the timing T2 and the model posture data at the timing T1 within the period Lb corresponding to the timing T2. This similarity is calculated in the same way as when the similarity S1 is calculated in step S111.
Similarly, the control part 14 calculates the similarity regarding each of timing T3, T4, T5. And the control part 14 calculates the statistics (for example, average value) of the similarity regarding each timing T2, T3, T4, T5 in the evaluation period La, and acquires the statistics as said similarity S6.
After the process of step S123 is executed, the control unit 14 (second comparison unit 86) performs an action performed by the player P in a period (past period: for example, period Lb in FIG. 20) in which the evaluation period is shifted in the past direction. Then, the similarity S7 with the exemplary action to be performed by the player P in the evaluation period is calculated (S124).
Here, the process of step S124 will be described with reference to FIG. For example, the control unit 14 acquires model posture data corresponding to individual timings T2, T3, T4, and T5 within the evaluation period La from the model data. In addition, the control unit 14 acquires posture data acquired at each timing T1, T2, T3, T4, and T5 within the period Lb (past period) from the storage unit 80.
And the control part 14 calculates the similarity regarding each timing T2, T3, T4, and T5 in the evaluation period La. For example, as the similarity regarding the timing T2, the control unit 14 calculates the similarity between the exemplary attitude data corresponding to the timing T2 and the attitude data acquired at the timing T1 within the period Lb corresponding to the timing T2. This similarity is calculated in the same way as when the similarity S1 is calculated in step S111.
Similarly, the control part 14 calculates the similarity regarding each of timing T3, T4, T5. And the control part 14 calculates the statistics (for example, average value) of the similarity regarding each timing T2, T3, T4, T5 in the evaluation period La, and acquires the statistics as said similarity S7.
After the process of step S124 is executed, the control unit 14 (second comparison unit 86) performs an operation in which the action performed by the player P in the evaluation period and the model action to be performed by the player P in the evaluation period are reversed left and right. The similarity S8 is calculated (S125).
Here, the process of step S125 will be described with reference to FIG. For example, the control unit 14 acquires posture data acquired at individual timings T2, T3, T4, and T5 within the evaluation period La from the storage unit 80. Further, the control unit 14 acquires model posture data corresponding to the individual timings T2, T3, T4, and T5 within the evaluation period La from the model data.
And the control part 14 produces | generates the left-right inversion attitude | position data corresponding to each timing T2, T3, T4, T5 in the evaluation period La. For example, the control unit 14 generates left / right reversed posture data corresponding to the timing T2 by horizontally flipping the model posture indicated by the model posture data corresponding to the timing T2. Similarly, the control unit 14 generates left / right inverted posture data corresponding to each of the timings T3, T4, and T5.
And the control part 14 calculates the similarity regarding each timing T2, T3, T4, and T5 in the evaluation period La. For example, as the degree of similarity at the timing T2, the control unit 14 calculates the degree of similarity between the horizontally reversed posture data corresponding to the timing T2 and the posture data acquired at the timing T2. This similarity is calculated in the same way as when the similarity S1 is calculated in step S111.
Similarly, the control part 14 calculates the similarity regarding each of timing T3, T4, T5. And the control part 14 calculates the statistics (for example, average value) of the similarity regarding each timing T2, T3, T4, T5 in the evaluation period La, and acquires the statistics as said similarity S8.
After the process of step S125 is executed, the control unit 14 (output control unit 88) causes the similarity S5 calculated in step S120 to be any one of the similarities S6 to S8 calculated in steps S123 to S125. Or not (S126).
When it is determined that any one of the similarities S6 to S8 is higher than the similarity S5, the control unit 14 (output control unit 88) updates the game screen as described below (S127). For example, the control unit 14 generates an image representing the virtual space 60 viewed from the virtual camera 64 on the VRAM. Further, the control unit 14 draws the score 50 of the player P at a predetermined position of the image generated on the VRAM. Further, the control unit 14 draws a message based on the comparison result between the similarities S6 to S8 and the similarity S5 at a predetermined position of the image generated on the VRAM.
For example, when the similarity S6 is higher than the similarity S5, the control unit 14 determines that the dance of the player P is behind the music, and draws a message indicating that (for example, the message 70 in FIG. 13). To do. For example, when the similarity S7 is higher than the similarity S5, the control unit 14 determines that the dance of the player P precedes the music, and draws a message indicating that. Further, for example, when the similarity S8 is higher than the similarity S5, the control unit 14 determines that the dance of the player P is reversed left and right, and displays a message to that effect (for example, the message 72 in FIG. 14). draw.
By the way, when a plurality of similarities among the similarities S6 to S8 are higher than the similarities S5, it may be determined that the dance defect of the player P could not be specified and the message may not be drawn. Alternatively, a message corresponding to the highest similarity among the plurality of similarities may be drawn.
On the other hand, when it is determined in step S126 that none of the similarities S6 to S8 is higher than the similarity S5, the control unit 14 updates the game screen (S119). Since the process in step S119 has already been described, the description thereof is omitted here.
After the processes of steps S118, S119, and S127 are executed, as shown in FIG. 22, the control unit 14 determines whether or not the game end condition is satisfied (S128). The “game end condition” is a condition as to whether or not the reproduction of music is completed, for example. 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 condition. For example, the “game end condition” may be 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 S127. Until it is determined that the game end condition is satisfied, the processes in steps S103 to S127 are repeatedly executed every predetermined time (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 (S129). 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, when the player P is not able to dance well, an output for specifically notifying the defect of the player P is performed (see FIGS. 13 and 14). . According to the game device 10, it is possible to assist the player P so that the player can grasp the disadvantages of his / her dance in detail.
The present invention can also be applied to a game other than a game in which the player P aims to dance a predetermined 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 the reference timing.
