Description

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

  2. Description of the Related Art Conventionally, a system is known in which an object arranged in a three-dimensional virtual space by computer graphics (CG) performs exercise motion including aerobic exercise and anaerobic exercise. 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, there are various types of exercise motions performed by the object, and there are those with a large movement of the whole body and those with a wide movement range, and those with a small movement and a narrow movement range. In the case of an exercise in which a part of a body part is operated with priority, an image in which an object is projected from a viewpoint position where the movement of the target body part can be clearly recognized is required. Therefore, a desirable viewpoint position in accordance with the motion motion is determined in advance, and in the initial state, an image showing the object is captured from the viewpoint position.

  In addition, when an object performs one certain motion, the body part to be observed may differ depending on the user. For example, when an object performs an exercise motion related to the movement of the arm, in order to observe the movement of the entire arm, an image showing the object from the front or side is desired. However, when focusing on the movement of the elbow among the movements of the entire arm, an image showing the object from the rear is desired. In response to such a demand, there is known one that can freely change the viewpoint position where the viewpoint for projecting the object is arranged (see, for example, Patent Document 1).

  Next, the output terminal 5 is configured by a known personal computer, like the distribution server 2. The output terminal 5 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 83 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.

  The electrical configuration of the output terminal 5 is the same as that of the distribution server 2, and the output terminal 5 includes a CPU 51 that controls the control. A ROM 52, a RAM 53, and an input / output 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 audio output unit 63 performs control to output BGM, sound effects, and the like that are reproduced in accordance with the video on which the figure 83 is projected, 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, for easy 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 83 in the present embodiment, but other than the figure, tools such as a barbell, a floor mat, and a rope for jumping rope, or a figure shaped like a person different from the figure 83 are used. Etc. are also included.

  In the three-dimensional virtual space 80, a figure 83 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 83. For ease of explanation, it is assumed that virtual cameras 81 (two of them are shown in FIG. 2) are arranged at each viewpoint. Each virtual camera 81 is previously set with a shooting direction 82, an angle of view, and an installation position of a virtual screen (not shown) (a screen for virtually forming an image obtained by viewing the figure 83 from the virtual camera 81). It shall be. Note that the shooting direction 82 of the virtual camera 81 is directed to the initial arrangement position (described later) of the figure 83. 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. Further, 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.

  In the present embodiment, it is assumed that symbols “A”, “B”, “C”, “D”,. In FIG. 2, as an example, symbols “A” to “F” are attached to some viewpoints. However, in fact, different viewpoints are attached to all the 24 viewpoints. To do. The two virtual cameras 81 shown in FIG. 2 are respectively arranged at the viewpoint “C” and the viewpoint “D”. In any output terminal 5, the world coordinates of the viewpoint position of the viewpoint specified by the symbols indicating these viewpoints are the same.

  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.

  Next, a process in which the figure 83 performs an exercise operation based on the motion data will be briefly described. The motion data is data for causing the figure 83 to reproduce the operation corresponding to the corresponding motion information. The motion data is represented in accordance with a known rule so that the position coordinates of each body part and detail of the figure 83 are positioned along the time axis to coordinates corresponding to individual motions corresponding to the motion information. Consists of data. Although the details are omitted, according to the motion data, for example, in the case where the head position of the figure 83 at the start of the movement operation is used as a reference, the relative position of the head position of the figure 83 after an arbitrary time. Coordinates can be specified. Also, the coordinates of each body part of the figure 83 are indicated by coordinates with the head position as the origin. If the coordinates of the head position of the figure 83 are determined, the coordinates of each body part and details are also determined. For example, based on the motion data corresponding to the motion information “March”, each body based on the coordinates of the head along the time axis so that the figure 83 performs a stepping action on the spot in the three-dimensional virtual space 80. The coordinates of the part and detail are determined (for example, the coordinates of the knee are alternately moved up and down as time passes).

  In the exercise support program to be described later, the operator 42 selects a lesson. A lesson is a list in which one or more pieces of motion information effective for achieving a predetermined exercise purpose are arranged in order of execution, and a series of exercise operations are performed. Each motion information included in one lesson is associated with tempo information, repetition information, performance information, motion information, and default viewpoint information.

  The tempo information is information indicating the operation speed of the exercise operation based on the motion data. The repetitive information is information indicating the number of times that one unit of motion information (one motion performed by the object based on the motion data) is repeated. The performance information is obtained by classifying the types of music output from the speaker 64 in accordance with the motion information by the number of beats (for example, the number of beats of the chorus portion of the music). The default viewpoint information is information for designating a viewpoint position as a default when there is no designation for the viewpoint at which the object is photographed (when there is no presentation viewpoint information to be described later). The HDD 7 of the output terminal 5 stores a table showing the contents of the lesson as lesson basic information. The lesson basic information is a table in which a lesson name is associated with each piece of information regarding the contents of the lesson according to the lesson name, and is created in advance and provided together with the exercise support program. When a new lesson is created, it may be distributed from the distribution server 2 and added to the basic lesson information. In addition, a new lesson may be created by the operator 42 and added to the lesson basic information.

  For example, as shown in FIG. 3, motion information of “half squat” and “quarter squat” is set in order in the lesson of “warming up”. The motion information of “half squat” is associated with “120” as tempo information, “4 times” as repetition information, “16 beats” as performance information, and viewpoint “B” (see FIG. 2) as default viewpoint information. It has been. Similarly, the motion information of “quarter squat” is associated with tempo information “120”, repetition information “4 times”, performance information “16 beats”, and viewpoint “B” as default viewpoint information. In the “main exercise” lesson, motion information of “march”, “front lunge”, and “back lunge” is set in order. The motion information of “March” is associated with tempo information “120”, repetition information “4 times”, performance information “16 beats”, and viewpoint “B” as default viewpoint information. The motion information of “front lunge” is associated with tempo information “120”, repetition information “8 times”, performance information “16 beats or 32 beats”, and viewpoint “B” as default viewpoint information. “Backrange” motion information is associated with tempo information “120”, repetition information “4 times”, performance information “32 beats”, and viewpoint “D” as default viewpoint information. In the “cool down” lesson, motion information of “thigh stretch” and “calf stretch” is set in order. The motion information of “thigh stretch” is associated with tempo information “60”, repetition information “four times”, performance information “BGM”, and viewpoint “D” as default viewpoint information. The motion information of “Calf Stretch” is associated with tempo information “60”, repetition information “4 times”, performance information “BGM”, and viewpoint “D” as default viewpoint information.

  For example, when the main exercise is selected as a lesson, motion information of “march”, “front lunge”, and “back lunge” is sequentially performed as the exercise motion by the figure 83. When “march” is performed, the figure 83 performs the march movement based on the motion data four times at the tempo 120, and at this time, the rust portion of 16 beats is played. The At this time, the figure 83 performing the march is photographed from the viewpoint “B”.

  As described above, the output terminal 5 obtains the information on the viewpoint position of the viewpoint used when generating the video showing the figure 83 from the distribution server 2. More specifically, in the output terminal 5, a request for acquiring presentation viewpoint information (described later) is output to the distribution server 2 by processing accompanying execution of the exercise support program. In the distribution server 2, the viewpoint position information suitable for photographing a video is distributed as presentation viewpoint information to the output terminal 5 in response to a request received from the output terminal 5 by processing accompanying execution of the distribution program. The Hereinafter, with reference to FIGS. 4 to 6 as appropriate with reference to FIG. 1, a process in which a video in which an object is projected from an appropriate viewpoint is generated in the output terminal 5 in cooperation with the distribution server 2 will be described. . Hereinafter, each step of the flowchart is abbreviated as “S”.

  First, the operation of the exercise support program executed in the output terminal 5 will be described. When the exercise support program shown in FIG. 4 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.

  Next, an initial screen (not shown) when the exercise support program is executed is displayed on the display unit 67. When the lesson start instruction is input by the operator 42 and the lesson is started (S11: YES), a lesson selection screen (not shown) is displayed. At the start of the lesson, input of ID information of the operator 42 is requested on an input screen (not shown), and the input ID information (for example, “ID_102”) is stored in the work storage area (work area) of the RAM 53. Is remembered.

  The operator 42 selects a desired lesson (lesson name) from each lesson included in the basic lesson information (S12). When a lesson is selected, each information (lesson name, tempo information, repetition information, performance information, motion information, default viewpoint information) included in the selected lesson is read from the HDD 7 from the basic lesson information. Each read information is associated with ID information and stored in the work area of the RAM 53 (S13).

  Of each information stored in S13, each motion information and corresponding tempo information, repetition information, and ID information are transmitted to the distribution server 2 as lesson information. At this time, a transmission request for presentation viewpoint information is also transmitted to the distribution server 2. As will be described later, to the distribution server 2, information on the viewpoint actually used (or selected) in accordance with the motion information at the output terminal 5 (hereinafter referred to as “selected viewpoint information”) is transmitted. In the distribution server 2, viewpoint information to be presented as an appropriate viewpoint (hereinafter referred to as “presentation viewpoint information”) is determined for each motion information. The output terminal 5 receives the presentation viewpoint information corresponding to each motion information from the distribution server 2 (S14). In the present embodiment, the selected viewpoint information corresponds to “second viewpoint information”, and the presentation viewpoint information corresponds to “first viewpoint information”.

  The default viewpoint information read in S13 is overwritten by the presentation viewpoint information received from the distribution server 2, and the lesson is started (S16: YES, S17). At this time, depending on the motion information, the corresponding presentation viewpoint information may not yet be determined in the distribution server 2. In this case, the default viewpoint information of the motion information whose presentation viewpoint information is not determined is not overwritten, and the lesson is started (S16: NO, S18).

  At the start of the lesson, in the world coordinate system 85, a position where the reference (the origin (for example, the head)) of the object (here, the figure 83) is arranged 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. Each viewpoint is provided with a virtual camera 81 (see FIG. 2), and for each virtual camera 81, a shooting direction 82, an angle of view, and an installation position of a virtual screen (not shown) are set. Further, among the motion information included in the lesson, the viewpoint arranged at the viewpoint position specified by the presentation viewpoint information (or default viewpoint information) associated with the motion information to be performed first is used to generate the video. The

  Motion data is read from the HDD 7 in accordance with the execution order of the motion information included in the lesson read into the RAM 53. The coordinate data and texture data of each body part of the object (figure 83) are also read, and the object (figure 83) is virtual at the arrangement position in the three-dimensional virtual space 80 determined by the arrangement setting process by known affine transformation. (See FIG. 2). Thereafter, the figure 83 is operated in accordance with the motion data in the three-dimensional virtual space 80.

  A video in which the figure 83 is projected from a viewpoint based on the presentation viewpoint information (or default viewpoint information) associated with the motion information is generated, and display on the display unit 67 of the monitor 57 is started. Then, recording of motion information and selected viewpoint information (hereinafter also referred to as “recording of log information”) is started (S19). Specifically, current motion information, current motion information repetition times, currently used viewpoint, current viewpoint usage time (based on usage start time and usage end time information), current Tempo information and ID information are recorded as log information. At this time, a viewpoint change flag (not shown) is set to a non-established state. The motion information is repeatedly executed according to repetition information (number of repetitions). “Repetition times” refers to information indicating the number of repetitions in the number of repetitions. .

  Recording of log information continues until the lesson ends. When the execution of all motion data corresponding to the motion information included in the lesson is completed and the lesson ends (S21: YES), the log information recording is ended (S24), and the process proceeds to S26.

  Note that while the log information is recorded (S21: NO), the remote controller 66 or the like is operated by the operator 42, and the viewpoint (current viewpoint) for capturing the video showing the figure 83 may be changed. . In this case (S22: YES), the viewpoint for capturing the video image showing the figure 83 is changed to the viewpoint selected by the operator 42 (S23). The changed viewpoint is recorded in the log information together with the use start time as the currently used viewpoint. At this time, the viewpoint change flag is set to be established. If there is no viewpoint changing operation by the operator 42 (S22: NO), as described above, recording of log information is continued until the lesson ends (S21: NO).

  For example, in the case of “main exercise” shown in FIG. 3, the default viewpoint information of “March” is the viewpoint “B”. If the presentation viewpoint information of “March” received from the distribution server 2 is the viewpoint “D”, the virtual camera 81 of the viewpoint “D” shown in FIG. 2 is photographed from the start of “March”. As described above, the “march” is repeated four times, but the log information (not shown) includes the motion information currently being performed, the number of repetitions, and the current viewpoint at the start of the first repetition. Are recorded. Further, the elapsed time from the start of the lesson, the current tempo information, and the ID information at the start of the first repetition are recorded. When the viewpoint is changed to, for example, “C” by the operator 42, a new viewpoint “C” is recorded in the log information. Further, the above-mentioned information such as the elapsed time from the start of the lesson at that time and motion information are also recorded. As described above, the log information is updated when the recording target is changed.

  Next, as shown in FIG. 4, in order to transmit lesson information to the distribution server 2, among the pieces of information stored in S13, the motion information and the corresponding tempo information, repetition information, and ID information are It is read again (S26). In addition, in order to prepare the selected viewpoint information to be transmitted to the distribution server 2 together with the lesson information, a process of extracting the viewpoint used for each piece of motion information is performed in the processes of S27 to S32. The viewpoint is extracted every time the motion information is repeated. When the viewpoint extraction for each time of all the motion information is completed, the extraction is completed (S27: YES), and the process proceeds to S33.

  Therefore, as long as viewpoint extraction for each time of all motion information is not completed (S27: NO), one unselected motion information is selected in the execution order of each motion information included in the lesson (S28). . When the viewpoint change flag is confirmed and the viewpoint change flag is established (S29: YES), the log information is referred to. Of the used viewpoints, the viewpoint that has been used for the longest time is identified in the repetition of the currently selected motion information. Specifically, from the log information, the use start time (elapsed time from the start of the lesson recorded as described above) and use end time (next Usage start time of the used viewpoint) is read out, and the usage time of the viewpoint is calculated. Similarly, when the usage times are calculated for all the viewpoints used in the repetition of the currently selected motion information, the usage times of the respective viewpoints are compared to identify the viewpoint with the longest usage time. The viewpoint position of the identified viewpoint is extracted as selected viewpoint information in the repetitive times of the currently selected motion information (S31).

  The presentation viewpoint information (or default viewpoint information) set in S16 to S18 and the selected viewpoint information indicating the viewpoint position of the viewpoint identified (extracted) as described above for the repetition times of the currently selected motion information The information indicating whether or not the viewpoint has been changed (whether or not the viewpoint change flag is established or not established) is associated and stored in the work area of the RAM 53. Thereafter, the process returns to S27.

  On the other hand, if the viewpoint change flag is confirmed in S29 and is not established (S29: NO), information indicating that there is no viewpoint change is set in the selected viewpoint information transmitted to the distribution server 2 (S32). ). As described above, the presentation viewpoint information, the selected viewpoint information, and the information on whether or not there is a viewpoint change are associated with the repetition times of the currently selected motion information and stored in the work area of the RAM 53. Returning to S27, the repetition time of unselected motion information is selected (S27: NO, S28), and the viewpoint extraction is continued.

  As described above, when the viewpoint extraction for each time of all the motion information is completed (S27: YES), the process proceeds to S33. Lesson information read in S26 and selected viewpoint information regarding the viewpoint extracted in S27 to S32 (including information on repeated times of motion information corresponding to the selected viewpoint information, presentation viewpoint information, and information on presence / absence of viewpoint change) Is transmitted to the distribution server 2 (S33). In the distribution server 2, the transmitted lesson information and the selected viewpoint information are associated with each other and stored in the database 3 as viewpoint change history information. When the lesson information and the selected viewpoint information are transmitted, an initial screen (not shown) when the exercise support program is executed is displayed on the display unit 67. When an instruction to end the exercise support program is input by the operator 42 (S34: YES), the execution of the exercise support program is ended. In the exercise support program, if the operator 42 does not input an instruction to start a lesson or end the exercise support program on the initial screen displayed on the display unit 67 (S11: NO, S34: NO), the initial screen The screen continues to display and waits for input.

  Next, the operation of the distribution program executed in the distribution server 2 will be described. When the distribution program shown in FIG. 5 is executed, a storage area corresponding to each process of the distribution program is secured in the RAM 23 and the HDD 37 in the initial setting. Also, variables, flags, counters, etc. used in the program are initialized. The following processing is executed by the CPU 21.

  In the distribution program, when a transmission request is received from the output terminal 5 so as to transmit the presentation viewpoint information to the output terminal 5 (S51: YES), the generation of the presentation viewpoint information and the transmission to the output terminal 5 in the processing of S52 to S54. The process proceeds to S64. Further, in the distribution program, when a reception request is received from the output terminal 5 so as to receive the selected viewpoint information transmitted from the output terminal 5 (S51: NO, S56: YES), the selected viewpoint information is processed in the processing of S57 to S63. Is received and stored in the database 3 (registration to the viewpoint change history information), and the process proceeds to S64. If an instruction to end the execution of the program is given (S64: YES), the execution of the distribution program is ended. Therefore, in the distribution program, unless the end of execution of the program is instructed (S64: NO), the process returns to S51 and waits for reception of a transmission request or reception request from the output terminal 5 (S51: NO, S56: NO, S64).

  When the distribution server 2 receives a transmission request for presentation viewpoint information (see S14 in FIG. 4) from the output terminal 5 (S51: YES), first, lesson information received from the output terminal 5 (corresponding to each motion information, respectively). Tempo information, repetition information, ID information) is stored in the work area of the RAM 23. Then, viewpoint determination processing is performed (S53).

  In the viewpoint determination process shown in FIG. 6, motion information included in the received lesson information is acquired and stored in the work area of the RAM 23 (S71). In order to prepare viewpoint information (presentation viewpoint information) corresponding to the motion information included in the received lesson information, a process of extracting an appropriate viewpoint for each motion information is performed in the processes of S72 to S79. The viewpoint is extracted for each motion information. The viewpoint determination process is terminated when viewpoint extraction for all motion information is completed (S72: YES), and the process returns to the main routine of the distribution program. Therefore, while the viewpoint extraction for all the motion information is not completed (S72: NO), one unselected motion information is selected in the execution order of each motion information included in the lesson (S73).

  The viewpoint change history information in the database 3 is referred to, and each piece of information associated with the selected motion information is extracted (S74). In the viewpoint change history information, lesson information transmitted from a plurality of output terminals 5 and selected viewpoint information (see S33 in FIG. 4) are stored. More specifically, in the viewpoint change history information, lesson information and selected viewpoint information respectively transmitted from a plurality of output terminals 5 connected to the distribution server 2 via the network 10 are additionally recorded. . In S74, the selected motion information and the corresponding selected viewpoint information are extracted from the various motion information recorded in the viewpoint change history information and the corresponding selected viewpoint information. For example, as shown in FIG. 7, when “March” is selected as the motion information, the motion information “March” and each piece of information associated with “March” (tempo information, Repeat information, ID information, repeat times, presentation viewpoint information, selected viewpoint information, presence / absence of viewpoint change) are extracted. FIG. 7 schematically illustrates viewpoint change history information obtained by extracting information including motion information “March”.

  From the extracted information, information in which the presence / absence of the viewpoint change is set to “none” is excluded. If the viewpoint change is “None”, it means that the viewpoint position has not been changed by the operator 42 throughout the lesson. Information in which the presence / absence of the viewpoint change is set to “none” is excluded from aggregation. For example, the information on the fifth to eighth lines is further deleted from the viewpoint change history information after extracting the information including “March” shown in FIG.

  In the remaining information, the selected viewpoint information is focused. Then, the selected viewpoint information is totaled, and the selection rate of each viewpoint is obtained (S76). For example, in FIG. 7, the information in the first to fourth lines and the ninth to twelfth lines is the information in which the viewpoint change is left as “present”. The selected viewpoint information is “B”, “D”, “D”, “D” in order from the first line, and “B”, “D”, “D”, “D” in order from the ninth line. D ". In this case, the number of all remaining selected viewpoint information (a total of all selected viewpoint information recorded in the extracted viewpoint change history information) is 8. Of these, two viewpoints “B” are selected. Also, six viewpoints “D” are selected. The viewpoint selection rate is obtained as a value obtained by dividing the number of selected viewpoints by the number of all selected viewpoint information recorded in the viewpoint change history information after extraction. Therefore, the selection rate of the viewpoint “B” is ¼ of the number of selections of the viewpoint “B”, 2 divided by the number of all selected viewpoint information and 8. Similarly, the selection rate of the viewpoint “D” is 3/4 of the value obtained by dividing the selection number 6 of the viewpoint “D” by the number 8 of all the selected viewpoint information. The other viewpoints (such as “A” and “C”) are not included in the selected viewpoint information of the extracted viewpoint change history information, and thus the selection rate is zero.

  The selection rate of the viewpoint having the highest selection rate is compared with a predetermined value, and if it is larger than the predetermined value (S77: YES), the viewpoint with the highest selection rate is appropriate for the currently selected motion information. As the viewpoint, the viewpoint information of the viewpoint is set as the presentation viewpoint information (S78). In the example of FIG. 7 described above, the viewpoint position of the viewpoint “D” whose selection rate is 3/4 is set as the presentation viewpoint information. On the other hand, if the selection rate of the viewpoint with the highest selection rate is equal to or less than a predetermined value (S77: NO), the presentation viewpoint information is not set as there is no appropriate viewpoint in the currently selected motion information. (S79). Thereafter, the process returns to S72. The predetermined value with which the selectivity is compared corresponds to the “reference value”.

  As described above, by repeating the processes of S72 to S79, a process of extracting an appropriate viewpoint for all motion information included in the lesson is performed (there may be no appropriate viewpoint). As described above, when viewpoint extraction for all motion information is completed (S72: YES), the viewpoint determination processing subroutine is terminated, and the process returns to the main routine of the distribution program.

  Returning to the main routine, viewpoint information (presentation viewpoint information) appropriate for each of the motion information included in the lesson performed at the output terminal 5 determined by the viewpoint determination process is sent to the requested output terminal 5. Is transmitted (S54). Proceeding to S64, as described above, the next transmission request or reception request from the output terminal 5 is waited (S64: NO, S51: NO, S56: NO).

  When receiving a request for receiving selected viewpoint information (see S33 in FIG. 4) from the output terminal 5 during standby (S56: YES), lesson information and selected viewpoint information transmitted from the output terminal 5 are received. (S57) and stored in the work area of the RAM 23 (S58). In the next processing of S59 to S63, the received lesson information and selected viewpoint information are stored in the database 3 for each motion information. While the storage processing of selected viewpoint information for all motion information is not completed (S59: NO), one unselected motion information is selected in the execution order of each motion information included in the lesson (S61). The selection of motion information is performed individually for each repetition of motion information.

  If the selected viewpoint information associated with the selected motion information (repeated times) has not been received (S62: NO), registration (additional writing) to the viewpoint change history information in the database 3 is not performed, and the process returns to S59. . If there is selected viewpoint information corresponding to the selected motion information (repeated times) (S62: YES), the viewpoint change history information in the database 3 includes the selected motion information and each information associated with the motion information. Is registered (added) (S63). As shown in FIG. 7, each piece of information associated with motion information is tempo information, repetition information, ID information, repetition times, presentation viewpoint information, selected viewpoint information, and information on whether or not there is a viewpoint change. Then, the process returns to S59.

  In this way, by repeating the processes of S59 to S63, the motion information included in the lesson and the information associated with each are registered in the viewpoint change history information of the database 3. When the processing of S59 to S63 for all motion information included in the lesson is completed (S59: YES), the process proceeds to S64. As described above, until the end of the distribution program is instructed (S64: NO), a standby for the next transmission request or reception request from the output terminal 5 is made (S51: NO, S56: NO).

  As described above, the output terminal 5 can display on the display unit 67 a video in which the object (figure 83) is projected at the viewpoint arranged at the viewpoint position corresponding to the presentation viewpoint information acquired from the distribution server 2. . For this reason, if the distribution server 2 prepares appropriate presentation viewpoint information, the output terminal 5 can obtain a video showing the object from the appropriate viewpoint. Since the process for obtaining the appropriate presentation viewpoint information only needs to be performed by the distribution server 2, the output terminal 5 is not burdened with the process for obtaining the appropriate presentation viewpoint information. On the other hand, in the distribution server 2, the selected viewpoint information having the highest selection rate and larger than a predetermined value (reference value) can be set as the presentation viewpoint information corresponding to the motion information. The selected viewpoint information used is not set as the presentation viewpoint information. In S77, when the selection rate of each viewpoint is simply higher than a predetermined value, the viewpoint position of the corresponding viewpoint may be set in the presentation viewpoint information in S78.

  Further, when the viewpoint position of the viewpoint is changed at the output terminal 5, the selected viewpoint information selected for the longest time among the selected viewpoint information selected by the change can be transmitted to the distribution server 2. Thus, in the distribution server 2, the selection viewpoint information selected for the longest time is used as a candidate for appropriate presentation viewpoint information when performing processing for obtaining appropriate presentation viewpoint information. The selected viewpoint information is not used as a candidate for appropriate presentation viewpoint information.

  In addition, when the exercise motion corresponding to the motion information is repeated, the same motion information may be changed to a different viewpoint each time the exercise motion is repeated. In such a case, if the selected viewpoint information for each repetition of the exercise motion is associated with the motion information, the selected viewpoint information can be used as a candidate for the appropriate presentation viewpoint information. Can be sought.

  Further, in the distribution server 2, the selected viewpoint information having the highest selection rate and larger than a predetermined value among the selected viewpoint information associated with the same motion information is set as the presentation viewpoint information corresponding to the motion information. Therefore, the selected viewpoint information used temporarily is not set as the presentation viewpoint information. As described above, selection viewpoint information whose selection rate is higher than a predetermined value may be set as the presentation viewpoint information.

  The configuration of the exercise support system shown in the above embodiment is an exemplification, and it goes without saying that the present invention can be variously modified. For example, in S31 of the exercise support program (see FIG. 4), the viewpoint that has been used the longest among the viewpoints that have been used is specified based on the usage time. However, the present invention is not limited to this, and log information is acquired at regular intervals, for example, and the viewpoint currently in use is recorded each time. When the selected viewpoint information is extracted in S31, the log information is recorded based on the log information. The frequency of use of the selected viewpoint (the number of uses of the target viewpoint / the number of uses of all viewpoints) may be obtained. Then, the viewpoint position of the viewpoint with the highest use frequency may be set in the selected viewpoint information. Alternatively, a reference frequency (corresponding to “reference ratio”) serving as a reference for the use frequency may be set in advance, and a viewpoint with a use frequency higher than the reference frequency may be set as the selected viewpoint information. In this case, if there are a plurality of viewpoints having a usage frequency higher than the reference frequency, each may be set as selected viewpoint information and transmitted to the distribution server 2.

  Further, for example, in the viewpoint determination process called in S53 of FIG. 5 in the distribution server 2, the ID information may be added to the extraction condition for extracting an appropriate viewpoint for the motion information. In this case, in S71, ID information may be acquired in addition to the motion information included in the lesson information. In S74, motion information and other information associated with the same ID information as the acquired ID information may be extracted from the viewpoint change history information.

  For example, as shown in FIG. 7, when “March” is selected as the motion information and the ID information is “ID — 102”, information including “March” and “ID — 102” is stored from the accumulated viewpoint change history information. Extracted. From the extracted information, information set with or without a viewpoint change is excluded. The ID information of the first to fourth lines of the viewpoint change history information is “ID_100”, and the ID information of the fifth to eighth lines is “ID_101”. Therefore, the information on the first to eighth lines is deleted, and the information on the ninth to twelfth lines whose ID information is “ID_102” is extracted. The number of all remaining selected viewpoint information (in order “B”, “D”, “D”, “D”) is 4, of which one viewpoint “B” and three viewpoints “D” are selected. Has been. Therefore, the selection rate of the viewpoint “B” is ¼, and the selection rate of the viewpoint “D” is 3/4. In S76, the viewpoint position of the viewpoint “D” whose selection rate is 3/4 is set as the presentation viewpoint information obtained from the information extracted by the ID information “ID — 102”.

  Thus, by adding the ID information of the operator 42 of the requested output terminal 5 to the extraction condition for extracting an appropriate viewpoint for the motion information, the selected viewpoint information of the preferred viewpoint of the operator 42 is obtained. It becomes easy to be presented as presentation viewpoint information. In addition, if arbitrary ID information can be input as the ID information transmitted in S71 at the output terminal 5, presentation viewpoint information based on the selected selected viewpoint information of another instructor different from the operator 42 is obtained. be able to. Specifically, for example, a desired lesson is selected by the operator 42 in S12 of the exercise support program described in FIG. 4, and desired ID information is input (or selected) on the selection screen at that time. Can be done. In S13, the ID information input in S12 may be associated with each piece of information included in the lesson selected in S12. By doing so, the ID information included in the lesson information transmitted to the distribution server 2 in S14 is not the ID information of the operator 42 but the ID information input in S12. In the above modification, the CPU 51 that acquires the desired ID information input on the selection screen corresponds to a “third acquisition unit”.

  For example, in the case of FIG. 7, even if the ID information of the operator 42 is “ID_102”, if the ID information desired by the operator 42 input in S12 is “ID_100”, the ID information is extracted in S74 above. The viewpoint change history information is information on the first to fourth lines. By obtaining the selection rate in the same manner as described above, the viewpoint position of the viewpoint “D” is output as the presentation viewpoint information obtained from the information extracted from the ID information “ID_100” and operated by the operator 42 of “ID — 102”. It will be presented to the terminal 5.

  In addition, for example, in the viewpoint determination process called in S53 of FIG. 5 in the distribution server 2, tempo information may be added to an extraction condition for extracting an appropriate viewpoint for motion information. In this case, in S71, tempo information may be acquired in addition to the motion information included in the lesson information. In S74, the tempo indicated by the acquired tempo information is used as a reference. The viewpoint information is changed from the motion information and other information associated with the tempo information indicating the tempo between the tempo obtained by subtracting a predetermined value from the reference tempo and the tempo obtained by adding the predetermined value to the reference tempo. What is necessary is just to make it extract from historical information.

  For example, in the case of FIG. 7, it is assumed that the tempo information of “March” of the lesson selected by the operator 42 is “120”. The predetermined value of tempo is set to “5”. In S74, since the reference tempo is set to “120” and the predetermined value is “5”, the first to fourth lines having values of “115” to “125” (120 ± 5) as the tempo information. Information on the 9th and 12th lines is extracted from the viewpoint change history information. The viewpoint selection rate obtained based on the extracted viewpoint change history information of the first to fourth lines and the ninth to twelfth lines is 1/4 for the viewpoint “B” and 3 / for the viewpoint “D”. 4 Therefore, in S76, the viewpoint position of the viewpoint “D” is set as the presentation viewpoint information obtained from the information extracted by the tempo information “120 ± 5”.

  In this way, tempo information is added to the extraction condition when an appropriate viewpoint for motion information is extracted. As a result, the distribution server 2 can obtain the selected viewpoint information of the viewpoint used in the tempo information close to the tempo information at which the object exercises in the output terminal 5 as the presentation viewpoint information. Thereby, the distribution server 2 can provide more appropriate presentation viewpoint information.

  Also in the above-described modified example, after S77, a process of comparing the selection rate of the viewpoint having the highest selection rate with a predetermined value is performed, and when the selection rate is higher than the predetermined value, the viewpoint of the viewpoint is determined in S78. The viewpoint position may be set in the presentation viewpoint information.

  Further, although the viewpoint position is an absolute position in the three-dimensional virtual space 80 in the present embodiment, it may be set as a relative position based on the object. In this case, the operator 42 may arbitrarily change the viewpoint position by an operation with the remote controller 66, the keyboard 61, or the mouse 62.

  Further, in S <b> 29 of the exercise support program of the output terminal 5, when there is no viewpoint change, the selected viewpoint information being processed may be discarded and the selected viewpoint information may not be transmitted to the distribution server 2. Alternatively, in the distribution program of the distribution server 2, for example, the presence / absence of the selected viewpoint information is confirmed in S62. In this process, the presence / absence of the viewpoint change is confirmed. The viewpoint information may not be registered. In this way, it is possible to save the trouble of performing processing for removing information without changing the viewpoint when obtaining an appropriate viewpoint.

  In the present embodiment, the CPU 51 that acquires the information of the lesson selected by the operator 42 in S13 corresponds to the “first acquisition unit”. The CPU 51 that acquires the presentation viewpoint information from the distribution server 2 in S14 corresponds to the “second acquisition unit”. The CPU 51 that outputs from the display control unit 56 a video signal for displaying on the display unit 67 of the monitor 57 the video imaged after starting the lesson in S17 corresponds to “display control means”. In S17, the CPU 51 that sets the viewpoint at which the figure 83 is projected corresponds to the “first setting unit”. In S <b> 19, the CPU 51 that records the change history of the viewpoint used for photographing the figure 83 as log information in the HDD 7 corresponds to “first storage unit”. In S33, the CPU 51 that transmits the lesson information and the selected viewpoint information to the distribution server 2 corresponds to the “first transmission unit”. In S23, the CPU 51 that changes the viewpoint for photographing the figure 83 corresponds to “changing means”.

  In S57, the CPU 21 that receives the lesson information and the selected viewpoint information from the output terminal 5 corresponds to “reception means”. In S63, the CPU 21 that registers the selected viewpoint information in the viewpoint change history information of the database 3 in association with the motion information corresponds to the “second storage unit”. In S78, the CPU 21 that sets the presentation viewpoint information using the viewpoint with the highest selection rate as the viewpoint of the motion information corresponds to the “second setting unit”. In S54, the CPU 21 that transmits the presentation viewpoint information to the output terminal 5 corresponds to the “second transmission unit”. In the modified example of S74, the CPU 21 that extracts the motion information and the selected viewpoint information associated with the tempo information indicating the tempo within a predetermined value range with respect to the reference tempo corresponds to the “determination unit”.
