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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

  As shown in FIG. 6, in the present embodiment, a case will be described in which the player position information includes at least part information regarding the position of the head and the position of the waist among the plurality of parts of the player 100. For example, the player position information includes the head P1, the shoulder P2, the upper left arm P3, the upper right arm P4, the lower left arm P5, the lower right arm P6, the back P7, the left arm P8, the right arm P9, and the left shin P10. Eleven three-dimensional coordinates corresponding to the right shin P11 are included.

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

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

[3. Game executed on game device]
The game apparatus 20 will describe a case where the player executes a game that moves a detection target (for example, a part of the player) so as to draw a trajectory according to the music. The detection target is used by the player to cause the game apparatus 20 to detect a trajectory drawn by the player, and is, for example, a part of the player. In other words, the game device 20 detects a locus drawn by the player by detecting a change in the position of the detection target. The player relies on the display content of the game screen displayed on the game device 20 and aims to draw a predetermined trajectory using hands and feet according to the music.

  FIG. 7 is a diagram illustrating an example of the game screen. As shown in FIG. 7, the game screen 30 includes a character 32, musical notes 34a and 34b (hereinafter collectively referred to simply as notes 34), and trajectory images 36a and 36b (hereinafter collectively referred to as trajectory images). 36) and a spotlight 38. In the game screen 30, the predetermined area 38a illuminated by the spotlight 38 may be set to have a higher brightness than the other areas.

  The display of the character 32 is controlled so as to perform the same action as the player. For example, when the player raises the right hand, the character 32 raises the right hand as viewed from the player. Similarly, when the player moves the part, the character 32 also operates to move the part corresponding to this part.

  The musical note 34 is generated from, for example, the spotlight 38 and moves so as to gradually approach the trajectory image 36 as the time for the player to draw a predetermined trajectory approaches. For example, when the part of the player draws a locus so that the part of the character 32 is located at the position where the note 34 and the locus image 36 overlap when the note 34 overlaps the locus image 36, the player is highly evaluated. Obtainable.

  The locus to be drawn by the player's part (detection target) is guided by the locus image 36. In the case of the screen example in FIG. 7, the trajectory to be drawn by the player is guided by the two reference trajectories indicated by the trajectory images 36 a and 36 b. The shape of the reference locus may be a predetermined shape. For example, the shape of the reference locus may be an arc as shown in FIG.

  In this way, the player draws a trajectory by moving the part so that the character 32 receives the note 34 falling from the spotlight 38 at the position of the trajectory image 36. In the present embodiment, as shown in FIG. 7, since a plurality of musical notes 34 are arranged in a row and approach the trajectory image 36, the player moves the part so that the character 32 traces the reference trajectory indicated by the trajectory image 36. Play the game.

The player position information is data acquired from the position detection device 1, and the game situation data is data generated and updated by a game program. Further, the control unit 21 functions as a means for acquiring various data stored in the game data storage unit 40.

The player is informed of when to move.

  The guide unit 44 displays a game screen 30 including a trajectory image 36 indicating a reference trajectory and a plurality of guide images (for example, musical notes 34) moving toward each of a plurality of target positions on the reference trajectory. For example, it is displayed on the display unit 27).

  The target position is a position set in the game screen 30 in order to guide the reference position on the game screen 30 to the player. That is, the target position is set based on the reference position indicated by the reference data, and the target position and the reference position maintain a certain relationship. In other words, the target position is the reference time point and the position to which the musical note 34 is moved to guide the reference position. For example, a position corresponding to the display position of the trajectory image 36 is set.

  The guide unit 44 moves each of the plurality of guide images (for example, the musical note 34) from a position different from the target position to which the guide image should move toward the target position to which the guide image should move. The guide unit 44 moves each of the plurality of guide images (for example, the musical note 34) toward a position (for example, a reference position) corresponding to the target position as a reference time point at which the detection target (for example, a player's part) should be close. The guide image is moved so as to approach the target position.

  A position different from the target position (hereinafter referred to as an initial position) is a position from which the note 34 is moved, and is a generation position (appearance position) of the note 34 defined in the game screen 30. In the present embodiment, a case where the initial position is a position in the spotlight 38 will be described.

  In the game screen 30, the guide unit 44 makes the distance between the current display position of the note 34 and the target position in the game screen 30 a distance corresponding to the time from the current time until the reference time point arrives. By controlling, the player is guided to the reference time point and the reference position. That is, on the game screen 30, the closer the current time point is to the reference time point, the narrower the interval between the current display position of the note 34 and the target position.

  Hereinafter, a display control method of the game screen 30 for the guide unit 44 to guide the reference time point and the reference position will be described. Here, a case will be described in which a game space is set in the game data storage unit 40 when the game is started, and a state in which the game space is viewed from a given viewpoint is displayed as the game screen 30.

  FIG. 13 shows a game space. As shown in FIG. 13, in the game space 60, the player should draw a character object 62 indicating the character 32, note objects 64a and 64b indicating the note 34 (hereinafter collectively referred to as a note object 64). Reference trajectory objects 66a and 66b (hereinafter collectively referred to as reference trajectory object 66) for guiding the trajectory, a spotlight object 68 indicating the spotlight 38, and a virtual camera 70 (viewpoint) are arranged. The

  Information indicating the position of each object is stored in, for example, game situation data. On the game screen 30, for example, an image showing a state where the game space 60 is viewed from the virtual camera 70 is displayed. For example, an object in the field of view determined based on the position and line-of-sight direction of the virtual camera 70 is displayed on the game screen 30.

  The character object 62 is arranged in the game space 60 based on the player position information, for example. For example, three-dimensional coordinates indicating each part of the character 32 are generated based on the three-dimensional coordinates of each part of the player indicated by the player position information. As shown in FIG. 13, for example, based on the player position information, the character Q's head Q1, shoulder Q2, left upper arm Q3, upper right arm Q4, left lower arm Q5, right lower arm Q6, back Q7, left thigh Q8, Eleven three-dimensional coordinates indicating the right thigh Q9, the left shin Q10, and the right shin Q11 are generated. For example, the character object 62 is generated based on the three-dimensional coordinates indicating each part of the character 32.

  FIG. 14 is a diagram for explaining a method for generating the character object 62. As shown in FIG. 14, in the present embodiment, a case will be described in which the character object 62 is generated so that the character 32 takes a posture that is a horizontally reversed posture of the player. In other words, the character object 62 is generated so that the character 32 moves (dance) obtained by horizontally inverting the player's movement (dance).

  For example, the three-dimensional coordinates of each part (head Q1 to right shin Q11) of the character 32 are obtained by using the three-dimensional coordinates of each part (head P1 to right shin P11) of the player as a reference plane (for example, Yp-Zp passing through the back P7). The coordinates are reversed on a plane parallel to the plane. When the three-dimensional coordinates of each part of the player indicated by the player position information change, the three-dimensional coordinates indicating each part of the character 32 also change.

  The character object 62 is arranged in the game space 60 by specifying the vertex coordinates of the polygon of the character object 62 based on the three-dimensional coordinates indicating each part of the character 32 specified as described above.

The positional relationship between the reference trajectory indicated by the trajectory A ₀ and the reference locus object 66a, and the positional relationship between the reference trajectory indicating a reference B ₀ and the reference locus object 66b, as shown in FIG. 14, left and right in the reference plane The positional relationship is reversed. That is, the reference trajectory object 66 is an object corresponding to the trajectory to be drawn by the player, and is generated based on the reference position, for example.

  The musical note object 64 is set in the game space 60 when a guidance start point at which the guide unit 44 should start guiding the reference point and the reference position comes. The musical note object 64 set in the game space 60 moves in the game space 60 during a guidance period in which the reference time point and the reference position are to be guided to the player. The guidance period is a period set based on the reference time, and is, for example, a period from a predetermined time (for example, one bar) before the reference time to the reference time. That is, the guidance start time is the start time of the guidance period.

  The musical note object 64 generated at the guidance start time moves toward the reference trajectory object 66.

  FIG. 15 is a diagram for explaining how the note object 64 moves. Here, a case where the note object 64 moves toward the reference trajectory object 66a will be described.

As shown in FIG. 15, for example, five target positions G _{1 to} G ₅ are set in the reference trajectory object 66. The target positions G _{1 to} G ₅ are set on the reference locus G ₀ indicated by the reference locus object 66 and set based on the reference position stored in the reference data. For example, the target positions G _{1 to} G ₅ are positions obtained by inverting the reference positions A _{1 to} A ₅ on the reference plane, respectively. That is, the reference trajectory G ₀ is a trajectory obtained by inverting the trajectory A ₀ to be drawn by the player on the reference plane.

In the game space 60, the musical note object 64 moves toward any _one of the target positions G _{1 to} G ₅ in the reference locus object 66, for example. Therefore, on the game screen 30, display control is performed so that the note 34 corresponding to the note object 64 moves toward the target position in the trajectory image 36.

The “target position of the note object 64” is a position set in the game space 60 (for example, any _{one of} the target positions G _{1 to} G ₅ ), and the “target position of the note 34” is The position set on the game screen 30 (the target position in the trajectory image 36).

  The position of the note object 64 is determined based on the elapsed time of the music being played and the reference data. For example, the position of the note object 64 is determined based on the time difference between the elapsed time of the music and the reference time, the generation position of the note object 64 (for example, the representative point of the spotlight object 68), and the distance of the target position. . Specifically, the position of the note object 64 is set to a position where the distance between the current position of the note object 64 and the target position is a distance corresponding to the remaining time until the reference time point arrives. .

Thereafter, the note object 64a is, from the representative point P ₀ in the spot light object 68, the case of moving toward the target position G ₁ in the reference locus object 66a. For example, the guidance start point visited, the note object 64a is arranged to be generated in the representative point P _0. Then, over time of the music, notes object 64a is moved toward the target position G _1. That is, as the current approaches the reference time, the note object 64a is moved so as to approach the target position G _1.

For example, if one bar before the time point of the reference point (guidance start point) visits, note object 64a is placed on the representative point P _0. (8-k) / 8 of the reference time point (k is any integer of 1-7) coordinates _{P k} note object 64a in the bars before the time, for example, the representative point _{P 0} and the target position _{G 1} This is the position of the point that internally divides the line segment connecting k by (8−k). Thus, by determining the display position of the note object 64, the movement of the note object 64a is controlled. When the reference point visited, the note object 64a reaches the target position _{G 1.}

  The target position of the note object 64 may be a position determined based on the reference position, and the target position of the note object 64 is a position obtained by inverting the reference position on the reference plane as in the above example. Alternatively, it may be a position where a distance from a position obtained by inverting the reference position on the reference plane is within a predetermined distance.

  In the present embodiment, a case where the note object 64 goes straight toward the target position will be described. However, the note 34 indicated by the note object 64 is moved from the initial position toward the target position on the game screen 30. The movement method of the note object 64 is not limited to the above example. For example, the musical note object 64 may be moved toward the target position so as to swing from side to side.

  On the game screen 30, the brightness of an area corresponding to the spotlight object 68 (for example, an area extending radially from the spotlight object 68 toward the character object 62) is made different from the brightness of other areas. Also good.

  In the present embodiment, as shown in FIG. 7, a case will be described in which a predetermined area 38 a set with a higher brightness than other areas is displayed on the game screen 30. Further, the initial position of the note 34 may be included in an area corresponding to the end of the predetermined area 38a. In this case, the musical note 34 is generated from the end of the predetermined area 38a having high brightness and moves toward the target position included in the predetermined area 38a. That is, the guide unit 44 moves the guide image (for example, the musical note 34) toward the target position within the predetermined area 38a.

  On the game screen 30, the colors of the musical note 34a and the trajectory image 36a may be different from the colors of the musical note 34b and the trajectory image 36b. By determining the colors of the note 34 and the trajectory image 36 in this manner, the player can easily understand which trajectory image 36 the note 34 is facing.

[6-5. Processing execution unit]
The process execution unit 46 is realized mainly by the control unit 21. The process execution unit 46 executes a game process based on the position information. For example, the process execution unit 46 controls the display of the character 32 based on the position of the part of the player indicated by the position information. Further, for example, the process execution unit 46 evaluates the movement of the detection target (for example, the player's part) based on the position information and the reference data.

  For example, the process execution unit 46 has a positional relationship between the position of the player indicated by the player position information at the evaluation target time set based on the reference time and the reference position indicated by the reference data (for example, a positional deviation amount). That is, the movement of the player's part is evaluated based on the distance.

  The evaluation target time point may be the reference time point itself, or may be any time point in the period from the first time before the reference time point to the second time after the reference time point. The lengths of the first time and the second time may be the same or different. For example, since the position detection device 1 may take a long time to generate the player position information, in order for the process execution unit 46 to accurately evaluate the operation of the player, the evaluation target time point is a predetermined time from the reference time point. It may be later.

  For example, the processing execution unit 46 determines whether or not the position shift amount between the position of the player's part (or the position of the part of the character 32) and the reference position at the evaluation target time point is within a predetermined range. Evaluate the operation. For example, when the positional deviation amount between the position of the player's part and the reference position is within a predetermined range, the process execution unit 46 gives a higher evaluation to the player than when the positional deviation amount is outside the predetermined range. give.

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

  First, as shown in FIG. 16, the control unit 21 generates a game space 60 in the main storage unit 22 and displays the game screen 30 on the display unit 27 (S101). The control unit 21 arranges the character object 62 in the game space 60 based on the player position information acquired from the position detection device 1 (S102). The control unit 21 reproduces the music based on the music data (S103).

  The control unit 21 refers to the reference data and determines whether or not the current time is within the guidance period (S104). If it is determined that the current time is not within the guidance period (S104; N), the process proceeds to S111.

  When it is determined that the current time is within the guidance period (S104; Y), it is determined whether or not the current time is the guidance start time (S105). When it is determined that the current time is the guidance start time (S105; Y), the control unit 21 newly generates a note object 64 and places it in the game space 60 (S106). In S106, for example, the note object 64 is arranged at the position of the representative point of the spotlight object 68. That is, the musical note 34 is displayed at the initial position in the game screen 30.

  On the other hand, when it is determined that the current time is not the guidance start time (S105; N), the control unit 21 moves the note object 64 based on the time difference between the current elapsed time of the music and the reference time (S107). In S107, the position of the note object 64 is set to a position where the distance between the current position of the note object 64 and the target position is a distance corresponding to the remaining time until the reference time point arrives.

  The control unit 21 determines whether or not the current time is the evaluation target time (S108). When it is determined that the current time is the evaluation target time (S108; Y), the control unit 21 moves the player's part based on the positional relationship between the position of the player's part indicated by the player position information and the reference position. Is evaluated (S109). The control unit 21 performs a game process based on the evaluation result in S109 (S110). For example, when the player gets a high evaluation, the score increases or effect processing is executed.

  When it is determined that the current time is not the evaluation target time (S108; N), the control unit 21 determines whether or not the end condition is satisfied (S111). The end condition may be a predetermined condition for ending this process. For example, the end condition may be a condition indicating whether or not the music ends, or a predetermined game over condition.

  If it is determined that the end condition is satisfied (S111; Y), the process ends. When it is determined that the end condition is not satisfied (S111; N), the process returns to S102. That is, the posture of the character 32 is changed based on the player position information acquired from the position detection device 1, and the reproduction of the music is continued.

  The game device 20 described above guides the reference position and the reference time to the player by moving the musical note 34 toward the trajectory image 36. The player aims to draw a predetermined locus by moving each part so that the character 32 receives the note 34 falling from the spotlight 38 at the position of the locus image 36. The player can easily grasp when and what kind of trajectory should be drawn based on the display content of the game screen 30.

  In the first embodiment, the case where the evaluation process for evaluating the movement of the player is executed is described as an example of the game process. However, the game process is executed based on the player position information. And what is necessary is just the process regarding a game. In addition, for example, the process execution unit 46 may execute a game process for controlling the posture of the character 32 based on the position of the part of the player indicated by the player position information.

[8. Embodiment 2]
Next, a second embodiment of the game device according to the present invention will be described. In the second embodiment, the locus to be drawn by the player is associated with any one of the player's parts. The player is limited so that the movement of the player's part is not evaluated unless the locus is drawn using the part associated with the locus to be drawn by the player.

For example, the trajectory _{A 0} is associated with the right lower arm P6 of the player, the trajectory _{B 0} are associated with the lower left arm P5 of the player. In this case, the player, the trajectory A _0, even if the locus so as to trace at a site other than the right lower arm P6, the player is restricted not possible to obtain a high evaluation. Similarly, the player, the trajectory B _0, be manipulated to trace at a site other than the lower left arm P5, the player is restricted not possible to obtain a high evaluation.

  Note that the functional block diagram realized in the game apparatus 20 of the second embodiment is the same as that of the first embodiment (FIG. 10), and thus illustration is omitted.

  The process execution unit 46 according to the second embodiment, for each of the plurality of parts of the player, the position of the part indicated by the position information acquired at the evaluation target time set based on the reference time and the position corresponding to the target position And evaluation means for evaluating the movement of the player based on the positional deviation. For example, the evaluation unit of the processing execution unit 46 may include the three-dimensional coordinates of the plurality of parts of the player indicated by the player position information at the evaluation target time point and the reference position corresponding to the target position (for example, Information on the positional deviation amount (distance) between the three-dimensional coordinates of the (reference position) is calculated.

  Further, the evaluation means of the process execution unit 46 evaluates the movement of the player based on whether or not the calculated positional deviation is within the reference range. For example, the evaluation means of the processing execution unit 46 determines that if the positional deviation amount (distance) between the position of any part of the player and the reference position is within the reference range, this positional deviation amount is out of the reference range. The player is given a higher evaluation than in the case of

  In addition, when the positional deviation between any one of the plurality of parts of the player and the position corresponding to the target position (for example, the reference position) is within a predetermined range, the process execution unit 46 identifies the part. Is stored in a storage means (for example, the game data storage unit 40). In the present embodiment, a case will be described in which the process execution unit 46 stores a part of a player whose positional deviation is within a predetermined range in the game data storage unit 40 in association with a locus to be drawn by the player.

  FIG. 17 is a diagram illustrating the association between the trajectory to be drawn by the player and the part of the player. As shown in FIG. 17, information for identifying a locus to be drawn by the player is associated with information for identifying a part of the player. Data indicating this association is stored in the game data storage unit 40, for example.

  In addition, when the identification information is stored in the storage unit (for example, the game data storage unit 40), the evaluation unit of the process execution unit 46 corresponds to the position of the part other than the part of the player indicated by the identification information and the target position. And restricting (suppressing) the evaluation of the movement of the player based on the positional deviation between the position and the position to be played. For example, the movement of the player is evaluated only based on the part of the player indicated by the identification information and the reference position on the trajectory associated with the identification information.

  In other words, the evaluation means of the process execution unit 46 evaluates the movement of the player's part based on the positional deviation between the position of the player's part indicated by the identification information and the position corresponding to the target position. The evaluation unit of the process execution unit 46, when the part of the player is associated with the locus to be drawn by the player, is based on the position of the part associated with the locus and the reference position on the locus. To evaluate the trajectory drawn by the player.

  18 and 19 are flowcharts showing an example of processing executed in the game device 20 of the second embodiment. The processes in FIGS. 18 and 19 are executed by the control unit 21 operating according to a program read from the optical disc when the game is started.

  As shown in FIG. 18, S201 to S208 are the same as S101 to S108, respectively, and thus the description thereof is omitted.

  When it is determined that the current time is the evaluation target time (S208; Y), the control unit 21 executes an evaluation process.

  Moving to FIG. 19, the control unit 21 determines whether or not the identification information for identifying the part of the player associated with the trajectory corresponding to the evaluation target time point is stored (S301). The trajectory corresponding to the evaluation target time point is a trajectory to be drawn by the player at the reference time point corresponding to the evaluation target time point. That is, the trajectory corresponding to the evaluation time point is a trajectory corresponding to the reference position at the reference time point.

  When it is determined that the identification information is stored (S301; Y), the control unit 21 evaluates the movement of the player based on the positional deviation between the position of the player's part indicated by the identification information and the reference position. (S302). That is, since the movement of the player is evaluated based on the positional deviation between the position of the part associated with the locus to be drawn by the player at the reference time point and the reference position on the locus, the position of the part other than this part The evaluation process is limited so that the movement of the player is not evaluated based on the positional deviation from the reference position on the trajectory.

  When it is not determined that the identification information is stored (S301; N), the control unit 21 determines whether or not there is a portion whose positional deviation from the reference position is within a predetermined range (S303). In S303, it is determined whether or not there is a reference position corresponding to the evaluation target time point, a plurality of parts indicated by the player position information, and a part whose positional deviation amount (distance) is within a predetermined range.

When it is determined that there is a part where the positional deviation is within the predetermined range (S303; Y), the control unit 21 stores the identification information for identifying this part in association with the locus corresponding to the reference position ( S304). For example, if the positional deviation amount between the right lower arm P6 and the reference position A ₁ of the player is within a predetermined range, and the lower right arm P6 and trajectory A ₀ is associated.

  The control unit 21 highly evaluates the player's movement (S305). That is, in S303, since it is determined that the positional deviation amount between the player's part and the reference position is within the predetermined range, the player is given higher evaluation than when the positional deviation amount is outside the predetermined range. .

  On the other hand, when it is not determined that there is a part where the positional deviation amount is within the predetermined range (S303; N), the control unit 21 performs a low evaluation on the movement of the player (S306). In this case, the association between the trajectory to be made by the player and the part of the player is not performed.

  S307 is the same as S110. S210 is the same as S111.

  According to the game device 20 of the second embodiment, the trajectory to be drawn by the player can be associated with the player's part. For example, when an operation is performed so that the player traces one locus using a large number of parts, it is difficult for the player to feel that the player is dancing. In this regard, according to the game device 20 of the second embodiment, an operation is performed so as to trace one trajectory using a portion associated with the trajectory, so that a trajectory that causes the player to dance is drawn. Will be able to.

  In the second embodiment, the case where the trajectory to be drawn by the player and the part of the player are stored in association with each other has been described. However, the identification information for identifying the part of the player may be stored. The identification information may not be stored in association with the locus to be drawn by the player. For example, when the identification information is not stored in the game data storage unit 40, the evaluation is not performed based on the position of the part other than the part indicated by the identification information and the reference position. Also good.

  In the second embodiment, the trajectory image 36 corresponding to the trajectory associated with the part of the player may be colored. In this case, the portion of the character 32 that is associated with the locus may be given the same color as the color applied to the locus. By doing so, the player can easily grasp at which part the locus should be drawn.

  The present invention is not limited to the embodiment described above, and can be appropriately changed without departing from the spirit of the present invention.

  (1) For example, in the embodiment, the case where the detection target is a part of the player has been described, but the detection target is not limited thereto. For example, when the game device 20 executes a game in which a touch pen or a player's finger is slid on the touch panel so as to draw a reference locus, the detection target may be the touch pen or the player's finger.

  In this case, the position information acquisition unit 42 acquires information on the contact position on the display screen (game screen 30) of the display unit 27. For example, the position information acquisition unit 42 is mainly realized by a touch panel provided to be superimposed on the display screen of the display unit 27. A musical note 34 approaching the trajectory image 36 displayed on the game screen 30 may be drawn so that the player traces the trajectory image 36 with a touch pen or a finger.

  In addition, for example, the detection target may be a light emitting unit provided in the game controller. In this case, the game apparatus 20 includes a CCD camera or the like and photographs the light emitting unit. The game apparatus 20 may acquire information related to the position change of the detection target based on the position and size of the light emitting unit in the captured image. The player may play the game by moving the detection target so that the trajectory to be drawn by the player is traced using the light emitting unit of the game controller.

  (2) Although the case where the initial position indicating the position where the note 34 is generated on the game screen 30 is the spotlight 38 has been described, the initial position may be a predetermined position within the game screen 30. . In addition, for example, the initial position may be an end area of the game screen 30. The musical note 34 may move from the end of the game screen 30 toward the target position, so that the player is guided to the reference position and the reference time point.

  (3) Moreover, although the case where the game screen 30 was displayed by arrange | positioning an object in the game space 60 was demonstrated, the display method of the game screen 30 is not restricted to this. The game screen 30 for guiding the reference position and the reference time point to the player may be displayed. For example, the game screen 30 may be displayed such that the image of the character 32 or the like is superimposed on the background image.

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

  (5) Moreover, the game performed in the game device 20 is not restricted to the game of embodiment. The game apparatus 20 may execute a game in which the player draws a locus using the detection target. In addition, for example, a game in which a part of the player draws a predetermined trajectory so as to perform gymnastics may be executed.
