Description

  The present invention relates to an exercise support apparatus, an exercise support method, and a program for supporting an exercise of moving a predetermined body part by displaying an image showing an object that exercises in a three-dimensional virtual space on a display unit.

  Conventionally, a system has been disclosed in which an object arranged in a three-dimensional virtual space by computer graphics (CG) executes an exercise operation including an aerobic exercise or an anaerobic exercise (see, for example, Patent Document 1). In CG, an object and a viewpoint (virtual camera) are generally arranged in a three-dimensional virtual space, and the object is photographed by the virtual camera and converted into a two-dimensional video. An image showing the object is displayed on a predetermined display unit, and a user of this system performs an exercise to move his / her body part based on the exercise operation performed by the object in the displayed image.

  By the way, the range of movement (movable range) of the object in the three-dimensional virtual space varies depending on the content of the motion performed by the object. For example, in a side step exercise classified as an aerobic exercise, an object performs an exercise operation that moves a body part while moving greatly relative to a reference position in a three-dimensional virtual space.

  An image showing an object is usually displayed at a standard display magnification. For this reason, for example, if the orientation (line-of-sight direction) of the virtual camera is fixed in a motion motion with a large movable range of the object, the object may protrude from the video. In such a case, you may use the image | video which image | photographed making the visual line direction of a virtual camera follow the object which moves in a three-dimensional virtual space. Further, there may be a case where an image showing the entire movable range is desired by reducing the display magnification according to the user's request.

JP 2009-112732 A

  However, conventionally, the display magnification has been changed by the operation of the device by the user, and it may be necessary to perform the operation during the exercise operation or whenever the type of the exercise operation is changed.

  The present invention has been made in order to solve the above-described problems. When displaying an image showing an object that moves in a three-dimensional virtual space on a display unit, the image is displayed according to the content of the movement. It is an object to provide an exercise support apparatus, an exercise support method, and a program capable of changing the display magnification of the exercise.

  According to the first aspect of the present invention, the first acquisition means for acquiring a plurality of pieces of exercise information representing the type of exercise for operating a predetermined body part and the body part are provided, and the exercise operation represented by the exercise information is performed. Second acquisition means for acquiring a reference display magnification that serves as a reference when displaying an image showing an object on a predetermined display unit; first determination means for determining a movable range of an exercise operation in which the object operates; Display control means for performing control to change a display magnification for displaying an image showing the object on the display unit so that the movable range falls within a display range of the display unit based on the reference display magnification. Are provided.

  According to the first aspect, control for enlarging or reducing the display magnification of the video displayed on the display unit with respect to the reference display magnification is performed according to the movable range of the motion motion of the object. As a result, it is not necessary for the user to instruct to change the display magnification using the input unit or the like while the user is exercising in accordance with the exercise operation performed by the object. Therefore, the user's exercise execution is not hindered. Further, the movable range can be surely contained within the display range of the display unit, and it is easy to see when an image showing the object is displayed on the display unit.

  The first aspect may further include third acquisition means for acquiring coordinate information in which the video image of the object is movable in the display unit. In this case, the first determination unit may determine the movable range of the motion motion in which the object operates based on the coordinate information acquired by the third acquisition unit. In this way, since a more accurate movable range can be obtained based on specific coordinate information, the movable range can be more reliably stored within the display range of the display unit.

  The first aspect may further include a determination unit that determines whether or not the movable range determined by the first determination unit is larger than a reference range as a reference. In this case, the display control means may make the display magnification smaller than the reference display magnification when the determination means determines that the movable range is larger than the reference range. In this way, the display magnification of the video displayed on the display unit is reduced according to the movable range. As a result, it is not necessary for the user to instruct the display magnification reduction by the input unit or the like while the user is exercising in accordance with the exercise operation performed by the object. Therefore, the user's exercise execution is not hindered.

  In the first aspect, the determination unit determines whether the movable range determined by the first determination unit is smaller than the reference range, and the display control unit determines whether the movable range is determined by the determination unit. When it is determined that it is smaller than the reference range, the display magnification may be larger than the reference display magnification. In this way, the display magnification of the video displayed on the display unit is increased according to the movable range. As a result, it is not necessary for the user to instruct the enlargement of the display magnification by the input unit or the like while the user is exercising in accordance with the exercise operation performed by the object. Therefore, the user's exercise execution is not hindered.

  The first aspect includes a selection unit that selects desired exercise information that is the desired exercise information from the plurality of pieces of exercise information acquired by the first acquisition unit, and the desired exercise that is selected by the selection unit. You may further provide the 4th acquisition means to acquire the list | wrist with which the information and the exercise | movement order information which show the order in which the said desired exercise | movement information is performed were matched. In this case, in the first aspect, the first determination means determines the movable range when the object moves the movement motion represented by the desired movement information according to the movement order information included in the list, The determining means determines whether the movable range determined by the first determining means is larger than the reference range and whether it is smaller than the reference range, and the display control means is determined by the determining means. When it is determined that the movable range is larger than the reference range, the display magnification is made larger than the reference display magnification, and the display control unit determines that the movable range is smaller than the reference range by the determination unit. When it is determined, the display magnification may be smaller than the reference display magnification.

  In this way, even when a plurality of exercises are successively executed according to a desired order, the user gives an instruction to enlarge or reduce the display magnification of the video displayed on the display unit for each exercise. Is not required to be directly input by an input unit or the like. In other words, each time the exercise is switched, the user is not burdened to change the display magnification. In particular, a user who desires to perform continuous exercise is not prevented from performing the exercise.

  The first aspect may further include an arrangement unit that arranges a viewpoint in which a line-of-sight direction and an angle of view are set in advance in the three-dimensional virtual space, and the object is captured, and the object. . In this case, in the first aspect, the display control means controls the movement of the arrangement position of the viewpoint along the line-of-sight direction with the angle of view fixed, or the angle of view with the arrangement position fixed. The display magnification may be controlled by performing control to change. The video image showing the object may be generated by photographing the object arranged in the three-dimensional virtual space from the viewpoint. In this way, it is possible to easily change the display magnification.

  The first aspect includes a second determining unit that determines a desired viewpoint that is one desired viewpoint among the plurality of viewpoints, wherein the plurality of viewpoints are arranged at each of a plurality of predetermined positions by the arranging unit. Further, it may be provided. In this case, the second acquisition unit may acquire the reference display magnification for displaying on the display unit the video image of the object projected from the desired viewpoint determined by the second determination unit. . By making it possible to determine a desired viewpoint from a plurality of viewpoints, an image in which an object is projected from a more desirable viewpoint can be displayed on the display unit.

  In the first aspect, after the display magnification is changed by the display control unit, the second determination unit determines a new desired viewpoint different from the currently determined desired viewpoint. The determination by the determination unit and the change of the display magnification by the display control unit may be executed again. When a new viewpoint is determined, the display magnification is changed again, so that the mismatch between the movable range and the reference range due to the difference in viewpoint position can be reliably eliminated.

  In the first aspect, the exercise information is information obtained by classifying motion information representing individual exercises for operating a predetermined body part for each type of exercise, and determination by the determination unit and the display control unit The change of the display magnification may be executed for each motion information. By changing the display magnification for each piece of motion information, it is possible to adjust the reference range according to the movable range for each different motion.

The drawings to be referred to are used for explaining the technical features that can be adopted by the present invention, and the configuration of the apparatus and the flowcharts of various processes described are not intended to be limited thereto. This is just an illustrative example.

  First, the configuration of the exercise support system 1 including the output terminal 5 will be described with reference to FIG. The exercise support system 1 includes one or more distribution servers 2 and one or more output terminals 5 that are electrically connected via a network 10 such as the Internet. The distribution server 2 is connected to a database 21 that stores motion data to be described later. The distribution server 2 distributes the motion data stored in the database 21 to the output terminal 5 periodically or upon request via the network 10.

  The motion data is data for causing a specific movement motion to be performed on an object (a figure A in the shape of a person) arranged in a three-dimensional virtual space 80 (see FIG. 3) described later. The motion data is associated with exercise information and motion information. Further, coordinate data based on a local coordinate system 84 (described later) of each body part of the object (figure A), similarly detailed coordinate data corresponding to each body part, texture data corresponding to the detail, and the like are also included. The exercise information is information representing the type of exercise. Specifically, exercise information includes “aerobic exercise”, “anaerobic exercise”, “stretch”, “yoga”, and the like. The motion information is information representing individual exercises classified by exercise information. Specifically, for example, motion information classified as “aerobic exercise” includes “march”, “front lunge”, “back lunge”, “side step”, and the like. The motion information classified as “anoxic exercise” includes “shoulder press”, “half squat”, “quarter squat”, and the like. The motion information classified as “stretch” includes “upper arm stretch”, “thigh stretch”, “calf stretch”, and the like. The motion information classified as “yoga” includes “cuckoo pose”, “sun worship pose”, “hero pose”, and the like. The database 21 stores motion data corresponding to various types of motion information classified into various types of exercise information.

  Next, the output terminal 5 is a known personal computer, for example, and functions as an exercise support device by installing and executing an exercise support program described later. The output terminal 5 is installed in, for example, a sports facility 4 or the like. In accordance with the execution of the exercise support program, the output terminal 5 generates an image showing the figure A performing the exercise operation according to the motion data, and displays it on the display unit 67 of the monitor 57 described later. The user 41 of the sports facility 4 performs an exercise to operate his / her body part using the image displayed on the display unit 67 as an example.

  Next, the electrical configuration of the output terminal 5 will be described. The output terminal 5 shown in FIG. 2 includes a CPU 51 that performs control. A ROM 52, a RAM 53, and an input / output (I / O) interface 55 are connected to the CPU 51 via a bus 54. The ROM 52 is a read-only storage device that stores programs such as BIOS executed by the CPU 51. The RAM 53 is a readable / writable storage device that temporarily stores data.

  Connected to the input / output interface 55 are a hard disk drive (HDD) 7, a multi-disk drive 58, a network communication unit 60, a display control unit 56, an audio output unit 63, a signal reception unit 65, a keyboard 61, and a mouse 62. . The multi-disk drive 58 reads data and programs from the disk ROM 59 when a disk ROM 59, which is a storage medium storing data, such as a CD-ROM or DVD-ROM, is inserted.

  A program read from the disk ROM 59 is installed in the HDD 7 serving as a storage device. Further, motion data distributed from the distribution server 2 via the network 10 is stored in association with the exercise information and the motion information. In the present embodiment, an exercise support program, which will be described later, is provided by being stored in the disk ROM 59, but may be provided by being stored in another storage medium such as a flash ROM. Alternatively, it may be provided by downloading from another terminal on the network connected via a network interface (not shown). The HDD 7 also distributes and stores BPM (Beats Per Minute) information, repetition information, music information, and the like stored in a database (not shown) from the distribution server 2. Although detailed explanation is omitted, these pieces of information include the operation speed when the figure A performs an exercise operation based on the motion data according to the motion information, the number of repetitions of the same operation, the BGM output from the speaker 64, and the like. Used as various elements.

  The display control unit 56 performs a drawing process for displaying on the display unit 67 of the monitor 57 a video image of the figure A that is generated in accordance with the execution of an exercise support program to be described later. A keyboard 61, a mouse 62, and a remote controller 66 are used by an operator 42 (for example, an instructor, shown in FIG. 1) to operate the output terminal 5 such as selecting exercise information and motion information, which will be described later, and changing a viewpoint. Used when doing. The signal receiving unit 65 receives a signal output from the remote controller 66 using a known means such as radio waves or light. The audio output unit 63 performs control to output BGM, sound effects, and the like that are reproduced in accordance with the video image of the object A from the speaker 64.

  Next, the three-dimensional virtual space 80 will be described with reference to FIG. The three-dimensional virtual space 80 is configured by coordinate data stored in a predetermined storage area that the CPU 51 secures in the RAM 53 as the exercise support program is executed. In the present embodiment, in order to facilitate understanding, a virtual space defined based on coordinate data or the like is schematically illustrated as a three-dimensional virtual space 80, for example, as shown in FIG. To do. Every object in the three-dimensional virtual space 80 is defined as coordinate data based on XYZ coordinate axes. Note that the object refers to the figure A in the present embodiment, but there are other tools such as a barbell, a floor mat, and a rope for jumping rope that are not shown in the figure, and a figure that is different from the figure A. Etc. are also included.

  In the three-dimensional virtual space 80, a figure A as an object is arranged at predetermined coordinates. Further, it is assumed that viewpoints (indicated by black corner points in the figure) are provided at 24 fixed positions surrounding the arrangement position (coordinates) of the figure A. For ease of explanation, it is assumed that virtual cameras 81 (two of them are shown in FIG. 3) are arranged at each viewpoint. Each virtual camera 81 has a shooting direction 82 (line-of-sight direction), field angle (vertical field angle θ1, horizontal field angle θ2 (see FIG. 4) (0 ° <θ1 <180 °, 0 ° <θ2 <), respectively. 180 °)), and an installation position of a virtual screen 88 (see FIG. 4) to be described later is set. Note that the shooting direction 82 is directed to the initial arrangement position (described later) of the figure A. Then, the video imaged in the three-dimensional virtual space 80 by the virtual camera 81 is used as an image on which an object is projected, which will be described later. Note that the number and types of objects arranged in the three-dimensional virtual space 80 and the number of viewpoints are examples, and can be arbitrarily increased or decreased. Further, the relationship between the arrangement position of the object and the viewpoint can be arbitrarily set.

  Here, a process in which the inside of the three-dimensional virtual space 80 is photographed by the virtual camera 81 and an image showing the object is generated will be briefly described. An image showing an object is that an object placed in the three-dimensional virtual space 80 is photographed every predetermined time and converted into a two-dimensional image, and the image is continuously displayed in time series. It is a thing.

  In the present embodiment, processing for converting an object arranged in the three-dimensional virtual space 80 into a two-dimensional image is performed by a series of coordinate conversion processing based on affine transformation. Affine transformation is a transformation method that is used for two-dimensional coordinate transformation and combines linear transformation such as enlargement, reduction, inversion, and parallel movement. By using affine transformation, the coordinates (local coordinates) set for each object arranged in the three-dimensional virtual space 80 are sequentially transformed into world coordinates, view coordinates, screen coordinates, and device coordinates to obtain a two-dimensional It can be a coordinate. Thereby, an image in which the object is viewed from the viewpoint is generated, and the image is continuously displayed to generate a video showing the object. Specific processing of coordinate transformation by this affine transformation is known. Therefore, an outline of a series of processes until local coordinates of the figure A as an example of the object arranged in the three-dimensional virtual space 80 is converted into device coordinates will be described below.

  As shown in FIG. 4, in the figure A, important body parts (indicated by black dots in the figure) such as the head, chest, hands, and feet are defined as coordinate data based on XYZ coordinate axes. . The coordinates of each of these body parts are respectively defined by position coordinates (coordinates of the local coordinate system 84) whose origin is the coordinates (for example, the coordinates of the head) used as the reference of the object. The details of the body are further defined by coordinate data based on each of these body parts and expressed by known texture mapping or the like. However, for the sake of simplification, description of the details is omitted here.

  A world in which the coordinates of the local coordinate system 84 of each body part of the figure A are defined by coordinate data based on the XYZ coordinate axes with the reference position set in the three-dimensional virtual space 80 as the origin and the entire three-dimensional virtual space 80 It is converted into the coordinates of the coordinate system 85. In addition, a viewpoint (virtual camera 81) for viewing the figure A is installed in the three-dimensional virtual space 80, and the position of the viewpoint is defined by the coordinates of the world coordinate system 85.

  The coordinates of the world coordinate system 85 defining the three-dimensional virtual space 80 are converted into the coordinates of the view coordinate system 86 with the position coordinates of the viewpoint as the origin. Then, a planar virtual screen 88 is defined in the three-dimensional virtual space 80 defined as the coordinates of the view coordinate system 86, and an image obtained by seeing the figure A through the virtual screen 88 from the virtual camera 81 is virtual. It is formed on the screen 88. Specifically, in the view coordinate system 86, a virtual line (indicated by a one-dot chain line in the figure) in which the coordinates of each body part of the figure A connect the virtual camera 81 (viewpoint) and each body part of the figure A is a virtual screen. The coordinates of the point that intersects with 88 (screen coordinates) are converted.

  The coordinates of each body part of the figure A thus converted to the coordinates on the virtual screen 88 are still defined as three-dimensional coordinates in the view coordinate system 86 at this point, and then converted to coordinates on a two-dimensional plane. Is done. That is, the coordinates (screen coordinates) on the virtual screen 88 indicated by the view coordinate system 86 are on the two-dimensional virtual screen 89 indicated by the device coordinate system 87 having a size displayed on the display unit 67 (see FIG. 1). Is converted to the coordinates (device coordinates).

  An image in which the figure A is projected on the virtual screen 88 viewed from the viewpoint arranged in the three-dimensional virtual space 80 by a series of coordinate transformations from local coordinates to device coordinates by the above affine transformation, It can be obtained as a screen 89. Coordinate transformation processing by affine transformation is performed by matrix calculation by the CPU 51 accompanying execution of an exercise support program described later. The virtual screen 89 is generated every predetermined time (for example, every 1/30 seconds) and is displayed on the display unit 67 in order, thereby providing a video showing the object.

  Note that, when the size of the virtual screen 88 is converted to the size displayed on the display unit 67 (that is, the size of the virtual screen 89), the magnification that is enlarged or reduced corresponds to the “display magnification” in the present invention. . In addition, as described above, each viewpoint (virtual camera 81) arranged in the three-dimensional virtual space 80 has a shooting direction 82 (line-of-sight direction), an angle of view (vertical angle of view θ1, horizontal angle of view θ2), The installation position of the virtual screen 88 is set. In this default state, the magnification when converting the size of the virtual screen 88 to the size displayed on the display unit 67 (the size of the virtual screen 89) corresponds to the “reference display magnification” in the present invention. The display magnification is changed by moving the virtual camera 81 along the shooting direction 82 or changing the angle of view of the virtual camera 81. In the present embodiment, the display magnification is changed by changing the angle of view of the virtual camera 81. Further, it is assumed that the installation position of the virtual screen 88 is not changed, and therefore, the display magnification is not affected by the difference in the installation position.

  Next, a process in which the figure A performs an exercise operation based on the motion data will be briefly described. The motion data is data for causing the figure A to reproduce the operation corresponding to the corresponding motion information. The motion data consists of data represented according to a known rule so that the position coordinates of each body part of the figure A in the local coordinate system 84 are positioned along the time axis. Although detailed description is omitted, according to the motion data, for example, when the position of the head of the figure A at the start of the movement operation is used as a reference, the relative position of the head of the figure A after an arbitrary time Coordinates can be specified. Further, as described above, the coordinates of each body part of the figure A are indicated by coordinates with the head position as the origin in the local coordinate system 84. Therefore, if the coordinates of the head position of the figure A are determined, The coordinates of the part are also determined.

  For example, based on the motion data corresponding to the motion information “March”, the coordinates of the head are determined along the time axis so that the figure A performs a stepping motion on the spot in the three-dimensional virtual space 80, and accordingly, The coordinates of each body part are determined. In the “march”, the position of the head, which is the reference for the position of each body part of the figure A, moves relatively little in the three-dimensional virtual space 80. On the other hand, for example, based on the motion data corresponding to the motion information “side step”, the figure A performs an operation of moving the amplitude to the left and right (based on the figure A) in the three-dimensional virtual space 80, as described above. The coordinates of each body part are determined along the time axis. In the “side step”, the position of the head serving as a reference for the position of each body part of the figure A has a relatively large position movement in the three-dimensional virtual space 80.

  Thus, the range in which the position of the head of the figure A moves in the three-dimensional virtual space 80 differs for each piece of motion information. Also, for each body part, the relative position with respect to the position of the head moves greatly or does not move so much depending on the content of the exercise operation. Therefore, the position where each body part of the figure A can exist in the three-dimensional virtual space 80 from the start to the end of the motion represented by one motion information differs for each motion information. .

  In the present embodiment, according to the exercise support program, the display magnification of the video is determined according to the range in which each body part of the figure A can exist in the three-dimensional virtual space 80, that is, the movable range. Hereinafter, the operation of the exercise support program installed in the output terminal 5 will be described with reference to FIG. 5 with reference to FIGS. Hereinafter, each step of the flowchart is abbreviated as “S”.

  The output terminal 5 of the present embodiment functions as an exercise support device by executing an exercise support program. The exercise support device displays an image showing an object (figure A) that performs an exercise operation in the three-dimensional virtual space 80 on the display unit 67, thereby allowing the user 41 to perform an exercise that moves his / her body part. It is a device to support. As described above, the motion data distributed periodically or upon request from the distribution server 2 is received by a reception program (not shown) executed by the output terminal 5 and stored in the HDD 7. In the exercise support program, motion data corresponding to the motion information classified as exercise information selected by the operator 42 is read from the HDD 7 and used to generate a video.

  When the exercise support program is executed, a storage area corresponding to each process of the exercise support program is secured in the RAM 53 and the HDD 7 in the initial setting. Also, variables, flags, counters, etc. used in the program are initialized. The following processing is executed by the CPU 51.

  First, a selection screen (not shown) for selecting a lesson is displayed on the display unit 67. A lesson is a list in which a plurality of effective exercise information and motion information are combined to achieve a predetermined exercise purpose, and a series of exercise operations are performed. More specifically, the lesson includes a list in which motion information is associated with BPM information, repetition information, music information, and the like (not shown) and arranged in order of execution.

  Although not shown, for example, in a certain lesson (for example, the first lesson), “anaerobic exercise” is set as an exercise equivalent to warm-up, “aerobic exercise” is set as an exercise equivalent to the main exercise, “Stretch” is set as an exercise equivalent to down. Furthermore, in the “anoxic exercise” for warming up, “half squat” and “quarter squat” are set in order as motion information, and BPM information, repetition information, and music information are associated with each other. Similarly, in the “aerobic exercise” of the main exercise, “march”, “front lunge”, and “back lunge” are set in order. Similarly, “thigh stretch” and “calf stretch” are set in order in the “stretch” of the cool-down. A first lesson that lists such a series of motion information is created in advance, and other various lessons are similarly created in advance and distributed from the distribution server 2. The HDD 7 of the output terminal 5 stores the delivered lessons (lesson names and their lists). In S11, the name of a desired lesson is selected by the operator 42 on a selection screen (not shown) (S11). The lesson may be created by the operator 42 by combining arbitrary exercise information and motion information.

  When a lesson is selected, individual motion information and its execution order are read from the HDD 7 based on the selected lesson list. Further, BPM information, repetition information, and music information corresponding to each motion information are read from the HDD 7. These pieces of information are stored in a predetermined storage area of the RAM 53 (S12).

  Next, an arrangement setting process is performed (S13). In the placement setting process, in the world coordinate system 85, a position where the reference (origin) in the local coordinate system 84 of the object (here, figure A) is placed in the three-dimensional virtual space 80 is set. Since the object moves its position in the three-dimensional virtual space 80 in accordance with the motion corresponding to the motion information, the initial arrangement position of the object is set here. Also, coordinates (world coordinate data) of arrangement positions such as a viewpoint and a light source (not shown) are set. A virtual camera 81 (see FIG. 3) is arranged at each viewpoint, and for each virtual camera 81, a shooting direction 82, a field angle (vertical field angle θ1, a horizontal field angle θ2 (see FIG. 4)), and a virtual screen. 88 installation positions are set. Further, one viewpoint used for generating a video among a plurality of viewpoints is determined to be preset as a default. The operator 42 may arbitrarily set the position of each viewpoint, the viewing direction of each virtual camera 81, the angle of view, and the installation position of the virtual screen 88.

  When the arrangement setting process is performed, the selected lesson is started (S14). Motion data is read from the HDD 7 in accordance with the list of lessons read into the RAM 53. The coordinate data and texture data of each body part of the object (figure A) are also read, and the object (figure A) is arranged at the arrangement position in the three-dimensional virtual space 80 determined by the arrangement setting process. Based on the affine transformation described above, the reference coordinates (here, the head coordinates) of the object are converted from the coordinates in the local coordinate system 84 to the coordinates in the world coordinate system 85. Further, detailed coordinates corresponding to each body part are converted from the local coordinate system 84 to the coordinates of the world coordinate system 85. Also, the size of the texture data and the coordinates to be pasted are set in the world coordinate system 85. As a result, the object (figure A) is virtually arranged in the three-dimensional virtual space 80 as shown in FIG. Thereafter, the figure A is operated in accordance with the motion data in the three-dimensional virtual space 80.

  Next, a reference display magnification is obtained (S16). The viewpoint photographing direction 82, the field angle (vertical field angle θ 1, horizontal field angle θ 2), and the installation position of the virtual screen 88 determined by the layout setting process are read from the RAM 53. Then, the size of the virtual screen 88 is calculated. An enlargement or reduction ratio for making the size of the virtual screen 88 coincide with the size of the virtual screen 89 displayed on the display unit 67 is calculated. The obtained magnification is stored in the RAM 53 as a reference display magnification.

  Next, position information of the movement is obtained (S17). The motion data of the currently performed motion information is read again from the HDD 7 and stored in the work storage area of the RAM 53. Then, from the motion data stored in the work storage area, the motion data that has been completed so far is deleted (S18).

  Next, the 3D map of the position information is performed (S19). As shown in FIG. 6, the second three-dimensional virtual space 79 is separately secured in the RAM 53, and the viewpoint (virtual camera 81) and the figure A determined in the arrangement setting process are arranged. Then, based on the remaining motion data deleted in S18, the motion movement of the figure A is performed in the second three-dimensional virtual space 79 until the end of the motion data. At this time, the operation of the figure A based on the motion data is performed in a state where information on the execution speed of the operation and the waiting time between the operations is ignored. In other words, when data processing based on one unit of motion is performed, the waiting time (weight) for timing adjustment to the next motion is 0, and the next one unit of motion is performed. Data processing is performed. Further, after data processing based on one unit of motion motion of Figure A is performed, data in the previous motion motion is not deleted when data processing based on the next one unit motion motion is performed. . Therefore, in the second three-dimensional virtual space 79, data processing based on the motion movement of the figure A based on the motion data is performed at high speed (weight 0) until the end of the current motion information, and further past data is stored. Instead of being deleted, they are stacked. As a result, after the current motion information is completed, an afterimage 93 of the figure A indicating the range in which the figure A moves is formed in the second three-dimensional virtual space 79 (see FIG. 6). The afterimage 93 has an appearance in which the contour lines of the figure A are overlapped from the start to the end of the motion information (actually, drawing processing is not performed, only data processing on the RAM 53 is performed, FIG. It represents a visual image.) More specifically, the afterimage 93 is obtained as coordinate data of the view coordinate system 86 with the virtual camera 81 as the origin. However, for the sake of simplification, the afterimage 93 may be obtained by overlapping the positions (coordinates) of each body part from the start to the end of one piece of motion information instead of the contour line of the figure A.

  Next, a movable range (shooting frame) is obtained (S21). In the view coordinate system 86, a cube 95 in which a plane 95 perpendicular to the shooting direction 82 of the viewpoint (virtual camera 81) is one of the side faces and the afterimage 93 is inscribed is formed as a shooting frame 94 in the three-dimensional virtual space 79. Is done. The plane 95 is a plane orthogonal to the shooting direction 82, and based on the coordinates of the four corners 96 of the plane 95 obtained from the coordinates of the shooting frame 94, the vertical field angle θ3 when the plane 95 is viewed from the viewpoint. A horizontal angle of view θ4 is obtained.

  Here, with reference to FIG. 7, a method of obtaining the field angles (vertical field angle θ3, horizontal field angle θ4) when the surface 95 is viewed from the viewpoint will be briefly described. FIG. 7 shows the coordinates of the virtual camera 81 in the Z axis direction in the view coordinate system 86 in which the installation position, that is, the viewpoint is P1, and the coordinates of P1 are the origin (x, y, z) = (0, 0, 0). Is 0. Further, the surface 95 of the imaging frame 94 orthogonal to the imaging direction 82 with the imaging direction 82 of the virtual camera 81 as the X-axis direction has a distance of a from the viewpoint (P1) based on the coordinates of the imaging frame 94. It is assumed that it is arranged at a position. In the view coordinate system 86, the coordinates of both ends P3 and P4 in the Y-axis direction (vertical direction) of the surface 95 from the coordinates of the corner portion 96 (see FIG. 6) of the surface 95 obtained in S21 are respectively P3 (a , B, 0) and P4 (a, -b, 0). Then, since tan (θ3 / 2) = b / a, it can be derived as θ3 = 2 · arctan (b / a). Similarly, the horizontal angle of view θ4 can be obtained based on the coordinates of the corner portion 96 of the surface 95.

  Next, as shown in FIG. 6, a projection surface 91 (dotted line) in which the surface 95 is projected onto the position of the virtual screen 88 is formed. The angle of view of the projection surface 91 is the same as that of the surface 95 in both the vertical field angle θ3 and the horizontal field angle θ4. Therefore, as shown in FIG. 7, the distance from the virtual camera 81 to the virtual screen 88 (see FIG. 6) is set to c. The coordinates of both ends P5 and P6 in the vertical direction of the projection plane 91 are P5 (c, c · tan (θ3 / 2), 0) and P6 (c, −c · tan (θ3 / 2), 0), respectively. Can be sought. Further, the coordinates of both ends of the projection surface 91 in the horizontal direction can be obtained in the same manner. Based on the coordinates thus obtained, the coordinates of the four corners of the projection surface 91 are determined. When the projection surface 91 formed in the three-dimensional virtual space 79 is viewed from the viewpoint, the afterimage 93 is within the projection surface 91.

  Next, an imaging range is obtained (S22). Here, the initial size of the virtual screen 88 calculated in S16 is obtained as the shooting range. The photographing direction 82 of the viewpoint, the angle of view (vertical angle of view θ1, horizontal angle of view θ2), and the installation position of the virtual screen 88 are read from the RAM 53, and the coordinates of the four corners of the virtual screen 88 are obtained in the view coordinate system 86.

  By comparing the coordinates of the four corners of the obtained virtual screen 88 and the coordinates of the four corners of the projection surface 91, the movable range of the figure A (that is, the size of the projection surface 91) becomes the shooting range (that is, the initial virtual screen 88 of the virtual screen 88). It is determined whether or not it is larger than the “reference range” (S23). If the movable range is larger than the shooting range (S23: YES), the shooting range is expanded (S24). As shown in FIG. 6, the virtual screen 88 is enlarged so that the projection plane 91 is within the enlarged virtual screen 92. As a result, the afterimage 93 is accommodated on the enlarged virtual screen 92.

  In the present embodiment, the virtual screen 88 is enlarged or reduced by changing the angle of view of the virtual camera 81. The virtual screen 88 is enlarged so that the angle of view (vertical angle of view θ5, horizontal angle of view θ6) of the virtual screen 92 after enlargement / reduction is equal to or greater than the angle of view of the projection surface 91 (vertical angle of view θ3, horizontal angle of view θ4). Or reduction is performed. For example, as shown in FIG. 9, if the size of the initial virtual screen 88 (virtual screen 88 a) is smaller than the size of the projection surface 91, the virtual screen 88 a is enlarged as indicated by an arrow E. The afterimage 93 inscribed in the imaging frame 94 is also inscribed in the projection surface 91 on which the surface 95 is projected at the position of the virtual screen 88. Therefore, the virtual screen 88a is enlarged so that the enlarged virtual screen 92 is larger than the size of the projection surface 91. On the other hand, if the size of the initial virtual screen 88 (virtual screen 88b) is smaller than the size of the projection surface 91, the virtual screen 88b is reduced as indicated by an arrow R. As described above, the virtual screen 88b is reduced so that the reduced virtual screen 92 is equal to or larger than the size of the projection surface 91.

  Note that the angle of view is changed by expanding or reducing the vertical angle of view and the horizontal angle of view at the same ratio. Therefore, the angle of view is changed so that θ1: θ2 = θ5: θ6 is satisfied, θ5 ≧ θ3 and θ6 ≧ θ4 are satisfied, and θ5 = θ3 or θ6 = θ4 is satisfied. The virtual screen 92 shown in FIG. 9 is an enlarged version of the virtual screen 88a with the aspect ratio of the screen being fixed, that is, satisfying θ1: θ2 = θ5: θ6. When the aspect ratio (θ3: θ4) of the projection surface 91 is different from the aspect ratio (θ5: θ6) of the enlarged virtual screen 92, the vertical size of the virtual screen 92 is projected as long as θ5 ≧ θ3 is satisfied. It becomes more than the vertical size of the surface 91. Furthermore, by satisfying θ6 ≧ θ4, the horizontal size of the virtual screen 92 becomes equal to or larger than the horizontal size of the projection surface 91. In addition, when θ5 = θ3 or θ6 = θ4 is satisfied, either the vertical or horizontal size of the projection surface 91 matches the vertical or horizontal size of the virtual screen 92. Therefore, the size of the projection surface 91 is the largest size that can be accommodated on the virtual screen 92. FIG. 9 shows an example in which the vertical size of the projection surface 91 is smaller than the vertical size of the virtual screen 92, but the horizontal size is the same. Returning to FIG. 5, the size of the enlarged / reduced virtual screen 92 is obtained as described above, and the enlargement or reduction magnification for matching the size of the virtual screen 89 displayed on the display unit 67 is the new display magnification. Calculated and stored in the RAM 53. Next, the process proceeds to S41.

  On the other hand, if the movable range is not larger than the shooting range in S23 (S23: NO), it is determined in S26 whether or not the movable range is smaller than the shooting range (S26). If the movable range is smaller than the shooting range (S26: YES), the shooting range is reduced (S27). That is, the virtual screen 88 is reduced, and the reduced virtual screen 92 satisfies the above conditions (θ1: θ2 = θ5: θ6, and θ5 ≧ θ3 and θ6 ≧ θ4, and θ5 = θ3 or θ6 = θ4). Generated to satisfy. The virtual screen 92 shown in FIG. 9 is also an example in which the virtual screen 88b is reduced while keeping the aspect ratio of the screen constant, that is, while satisfying θ1: θ2 = θ5: θ6. The virtual screen 88b is reduced in the same manner as described above so that the projection surface 91 has the maximum size that can be accommodated in the virtual screen 92. As described above, a new display magnification is also calculated and stored in the RAM 53. Next, the process proceeds to S41. If the movable range is not smaller than the shooting range in S26 (S26: NO), the movable range coincides with the shooting range, and the process proceeds to S41 as it is.

  In S <b> 41, a video that shows the figure A whose operation has been started in the three-dimensional virtual space 80 is generated and output so as to be displayed on the display unit 67 of the monitor 57 (S <b> 41). The figure A is shot by the virtual camera 81 in the three-dimensional virtual space 80. At this time, the angle of view of the virtual screen 88 in the three-dimensional virtual space 80 is enlarged, and the enlarged / reduced virtual screen 92 (vertical angle of view θ5, horizontal angle of view θ6) is reproduced in the three-dimensional virtual space 80. The By the above affine transformation, the virtual screen 89 is changed from the scaled virtual screen 92 to the scaled screen based on the display magnification obtained in S24 or S27 every predetermined time (for example, every frame of the video (about 1/30 second)). Generated. Then, the generated virtual screen 89 is displayed on the display unit 67 in order, thereby providing a video showing the object.

  Next, the process proceeds to S42, and if the figure A has not performed an exercise operation corresponding to all the motion information included in the list of lessons and the lesson is not completed (S42: NO), the process proceeds to S43. In S43, if the change instruction for the currently determined viewpoint (virtual camera 81) is not input from the remote controller 66 (or keyboard 61 or mouse 62) by the operator 42 (S43: NO), the process proceeds to S44. In S44, if the motion corresponding to the motion information currently being performed by the figure A has not been completed yet (S44: NO), the output of the video showing the object started in S41 is continued. Return to.

  If the motion operation corresponding to the motion information currently being performed by the figure A is completed while S42 to S44 are repeated (S44: YES), the motion operation corresponding to the motion information of the next execution order included in the list Is started (S46). That is, the motion data corresponding to the motion information in the next execution order is read from the HDD 7, and the figure A arranged in the three-dimensional virtual space 80 is operated according to the motion data as in S14. Then, returning to S16, the processes of S16 to S41 described above are executed, and an image showing the object is output.

  In addition, when the operator 42 issues a change instruction to the currently determined viewpoint (virtual camera 81) while S42 to S44 are repeated, the newly determined viewpoint is a three-dimensional virtual viewpoint. It is installed in the space 80 (S47). Then, returning to S16, the processes of S16 to S41 described above are executed, and an image in which the object is projected from the newly determined viewpoint is output.

  When the figure A finishes the motion corresponding to all the motion information included in the lesson list and the lesson ends (S42: YES), the video output to the display unit 67 is stopped (S48), and the exercise support program The execution of is terminated.

  As described above, in the output terminal 5, the display magnification of the video displayed on the display unit 67 is increased or decreased according to the movable range. As a result, while the user 41 is exercising in accordance with the exercise operation performed by the object, the display magnification is enlarged or reduced by the user 41 or the operator 42 by the remote controller 66 or the keyboard 61 or the mouse 62. There is no need to give an instruction and the user 41 does not interfere with the exercise. Further, when the shooting range is enlarged or reduced, the movable range can be surely kept within the shooting range, so that it is easy to see when the video image showing the object is displayed on the display unit 67. Specifically, the size (field angle) of the projection surface 91 is obtained based on the coordinates of the corner portion 96 of the surface 95 of the photographing frame 94, and the virtual screen 88 is enlarged or reduced based on this. Thus, the display magnification is obtained. In this way, since the more accurate movable range of the object can be obtained based on the coordinate information, the movable range can be more reliably stored within the display range of the display unit 67.

  Even if there are a plurality of pieces of motion information included in the lesson list, the shooting range can be enlarged or reduced for each piece of motion information. This eliminates the need for the user 41 or the operator 42 to give an instruction to change the display magnification of the video displayed on the display unit 67 by using the remote controller 66 or the keyboard 61 or the mouse 62 for each motion information. In other words, since the burden of changing the display magnification is not applied to the user 41 or the operator 42 every time the exercise is switched, the user 41 who desires to perform continuous exercise is particularly disturbed. There is nothing. In addition, by photographing an object arranged in the three-dimensional virtual space 80 from a viewpoint, and generating a video showing the object, it is possible to easily enlarge or reduce the photographing range and thus change the display magnification. it can. Further, since the viewpoint can be changed and a desired viewpoint can be determined from a plurality of viewpoints, an image in which an object is projected from a more desirable viewpoint can be displayed on the display unit 67. Further, when the viewpoint is changed, the processing of S16 to S41 is performed again, and the imaging range is expanded or reduced in accordance with the movable range, so that a mismatch between the movable range and the imaging range due to a difference in viewpoint position is ensured. Can be resolved. In addition, since the shooting range is changed for each motion information, the shooting range can be adjusted according to the movable range for each different motion.

  The configuration of the exercise support apparatus shown in the above embodiment is an exemplification, and it goes without saying that the present invention can be variously modified. For example, in the present embodiment, the viewpoint change performed in S47 is determined by providing a plurality of viewpoints in advance and selecting an arbitrary viewpoint as shown in FIG. That is, each viewpoint has an absolute arrangement position in the three-dimensional virtual space 80, and the positional relationship between the object and each viewpoint has an absolute positional relationship. Of course, the viewpoint arrangement position based on the object may be set so that the positional relation between the object and the viewpoint has a relative positional relation. Alternatively, the position of the viewpoint may be arbitrarily changed by an operation with the remote controller 66, the keyboard 61, or the mouse 62.

  The size of the virtual screen 92 after the enlargement / reduction is set to be equal to or larger than the size of the projection surface 91 (θ5 ≧ θ3 and θ6 ≧ θ4, and θ5 = θ3 or θ6 = θ4). The size of the enlarged and reduced virtual screen 92 may be larger than the size of the projection surface 91 by a predetermined size. For example, θ5 ≧ 1.1 × θ3 and θ6 ≧ 1.1 × θ4, and θ5 ≧ 1.1 × θ3 and θ6 ≧ 1.1 × θ4 in order that the size of the enlarged and reduced virtual screen 92 is 1.1 times the size of the projection surface 91 It is sufficient to satisfy θ5 = 1.1 × θ3 or θ6 = 1.1 × θ4. In this way, it is possible to set a shooting range having a margin with respect to the movable range.

  In the present embodiment, the output terminal 5 generates a video showing the object and outputs it to the display unit 67. A video in which an object is projected in advance may be distributed from the distribution server 2 to the output terminal 5 together with motion information corresponding to the video. In this case, the movable range obtained in S21 is the internal reproduction of all the video corresponding to the motion information (reproduction without displaying it on the display unit 67), and the portion changed in units of frames (that is, the object operates in the video). It may be obtained by comparing the portion). In this case, however, it is desirable that the video to be distributed is a video shot so that the movable range of the object is always within the video, and the output terminal 5 reduces the shooting range (increases the display magnification). What is necessary is just to process.

  Further, the processing (S16 to S41) for capturing and visualizing the motion of the object in the three-dimensional virtual space 80 may be performed by the distribution server 2. In this case, a lesson list or a viewpoint position change instruction may be transmitted from the output terminal 5 to the distribution server 2, and the video generated by the distribution server 2 may be received and reproduced.

  In S24 and S27, the virtual screen 88 is enlarged or reduced in size to the angle of view (θ1, θ2) in order to enlarge or reduce the imaging range (change the display magnification). Of course, the virtual screen 88 is enlarged by fixing the angle of view (θ1, θ2) and moving the viewpoint (virtual camera 81) closer to or away from the position of the virtual screen 88 along the shooting direction 82. Alternatively, a reduced virtual screen 92 may be formed. That is, the angle of view (θ1, θ2) of the virtual screen 88 satisfies θ5 = θ1 and θ6 = θ2 with respect to the angle of view (θ5, θ6) of the virtual screen 92 after enlargement / reduction. In this state, if the distance x between the virtual camera 81 and the virtual screen 88 decreases, the value of x · tan θ1 indicating the vertical length of the virtual screen 88 and the value of x · tan θ2 indicating the horizontal length are obtained. Since both become smaller, the virtual screen 92 can be reduced with respect to the virtual screen 88. On the other hand, as the distance x increases, the values of x · tan θ5 and x · tan θ6 increase, so that the virtual screen 92 can be enlarged with respect to the virtual screen 88.

  Further, when the motion of the object is intense, the virtual screen 88 may be enlarged or reduced so as to be larger than the projection plane 91. That is, when the motion motion of the object is intense, the display magnification may be made smaller than the size reduced in the present embodiment. Specifically, as shown in the flowchart of FIG. 8, after the shooting range is determined in S24 or S26: NO or S26, the processing of S31 to S33 is performed, and then the video showing the object is output in S41. do it.

  In the modified example of the exercise support program shown in FIG. 8, when the 3D map of the position information is performed in S19, the coordinates of each body part are recorded for each frame of the video. In S31, the movement distance of the coordinate between each frame is calculated | required for every body part, and the maximum value of the movement distance for each body part is calculated | required as (DELTA) value (S31). The Δ value of each body part is compared with a standard value determined in advance for each body part. If the Δ values of all body parts are equal to or less than the standard value (S32: NO), the process proceeds directly to S41. If there is a body part whose Δ value is larger than the standard value (S32: YES), the specified angle is multiplied to the angle of view of the virtual screen 88 or the virtual screen 92 after scaling in S22 to S27 ( S33), the process proceeds to S41. That is, similarly to the above-described modified example, it is possible to set an imaging range having a margin with respect to the movable range. In this way, when the motion of the object is intense, it is possible to further reduce the display magnification and make it easy to see the entire movable range in the video image of the object.

  Further, in the present embodiment, when the movable range is smaller than the photographing range, the photographing range is reduced (the display magnification is increased) so that the photographing range matches the movable range. In this case, the reduction of the shooting range may be made smaller than the movable range. In this way, it is possible to see the object in more detail in the video that shows the object that performs the motion. In particular, in the case of an exercise in which a part of the body part is mainly operated, the part can be enlarged and viewed.

  In the present embodiment, the CPU 51 that acquires lesson information in S12 corresponds to a “first acquisition unit”. In S <b> 16, the CPU 51 for obtaining the reference display magnification corresponds to “second acquisition unit”. In S21, the CPU 51 for obtaining the movable range (imaging frame 94) corresponds to the “first determining means”, and the CPU 51 for obtaining the coordinates of the four corners 96 of the surface 95 from the coordinates of the imaging frame 94 is “third acquisition”. It corresponds to “means”. The CPU 51 that compares the movable range and the reference range (shooting range) in S23 and S26 corresponds to “determination means”.

Further, the CPU 51 that acquires a list of lessons from the distribution server 2 periodically or in response to a request corresponds to a “fourth acquisition unit”. Further, as described above, the list of lessons may be arbitrarily set by the operator 42. In this case, exercise information or motion information is presented to the display unit 67 to the operator 42, and the remote control 66 is displayed. Alternatively, the CPU 51 that makes it possible to select a desired one by operating the keyboard 61 or the mouse 62 corresponds to “selecting means”. The CPU 51 that performs the arrangement setting process in S13 corresponds to an “arranging unit”. In S <b> 47, the CPU 51 that determines the viewpoint position as an arbitrary viewpoint position selected by the operator 42 corresponds to the “second determination unit”.
