Description

  The present invention relates to a method for distributing exercise content including motion data representing a skeleton shape of a three-dimensional model.

  Japanese Patent Application Laid-Open No. 10-40418 discloses a technique in which data of a skeleton structure arranged in a three-dimensional space by CG (Computer Graphics) is transmitted and received between different devices. The skeletal structure data represents the skeleton structure of the body part of a predetermined character. In Japanese Patent Laid-Open No. 10-40418, skeleton structure data at each time is defined. The character can take a predetermined posture in the three-dimensional virtual space by the data of the defined skeleton structure. Data of the defined skeleton structure is output to the display unit along the time axis, and CG processing is executed on the data of the skeleton structure. Through the processing described above, a three-dimensional CG that causes the character to perform a predetermined action is generated. In this specification, the skeleton structure data output along the time axis is referred to as motion data. Japanese Patent Laid-Open No. 10-40418 discloses a technique in which motion data is transmitted and received between different devices.

  On the other hand, Japanese Patent Application Laid-Open No. 2009-112732 discloses a system in which a person arranged in a three-dimensional space by CG executes exercise motion including aerobic exercise and anaerobic exercise. A person arranged in a three-dimensional space described in Japanese Patent Application Laid-Open No. 2009-112732 performs a predetermined motion based on motion data disclosed in Japanese Patent Application Laid-Open No. 10-40418.

Japanese Patent Laid-Open No. 10-40418 JP 2009-112732 A

  In the system disclosed in Japanese Patent Application Laid-Open No. 2009-112732, an exercise lesson in which a plurality of exercise operations are combined is performed. Each motion motion is associated with motion data representing each motion motion. The plurality of types of motion data constituting the exercise lesson are continuously output by the display unit, so that the exercise lesson is provided to the system user as one exercise content.

  In general, an exercise lesson may be generated by combining existing exercises or may be generated by a newly considered exercise. When a new athletic lesson is provided to the user by the athletic content provider, the athletic lesson is transmitted from the server device installed in the network to the terminal device used by the user. The transmitted exercise lesson is stored in the storage unit of the terminal device. The exercise lesson includes motion data constituting the exercise lesson and CG data for displaying the motion data by CG. When a new exercise lesson is provided to the user by the content provider, the motion data included in the new exercise lesson may include motion data already stored in the storage unit of the terminal device. Therefore, even when a new exercise lesson is generated, if all the motion data included in the exercise lesson is transmitted, there is a possibility that the motion data already stored on the terminal side is also transmitted. Since the already stored motion data is transmitted redundantly, the network bandwidth is compressed or the distribution time is extended due to the increase in data volume, so the distribution efficiency is poor.

  According to the first aspect of the present invention, when the first determination unit determines that there is motion data that is not stored in the third storage unit, the requesting unit is a motion that is not stored in the third storage unit. The information processing is requested to acquire data. Accordingly, there is no need to request motion data already stored in duplicate. As a result, the distribution efficiency of motion data can be improved without causing the network band to be compressed or the distribution time to be increased due to an increase in the amount of data.

  According to the second aspect of the present invention, when the motion data is displayed on the display unit, the processing unit executes computer graphic processing representing a character on the motion data. Therefore, since the terminal device is provided with a processing unit that executes computer graphic processing on motion data, it is not necessary to send information regarding computer graphic processing when distributing motion data. As a result, the distribution efficiency of motion data can be improved without causing the network band to be compressed or the distribution time to be increased due to an increase in the amount of data.

  According to the third aspect of the present invention, when it is determined by the third determination unit that there is motion data corresponding to the first identification information that is not stored in the second storage unit, the deletion unit performs the second storage. The motion data corresponding to the first identification information not stored in the unit is deleted from the third storage unit. Since motion data that is not registered in the exercise list is not used as exercise content, it becomes unnecessary motion data. Accordingly, motion data that is unlikely to be acquired again via the network is deleted. As a result, the storage capacity of the storage unit that stores motion data can be used efficiently, and the distribution efficiency of motion data can be reduced without reducing network bandwidth or extending the distribution time due to an increase in data volume. Can be raised.

  According to the fourth aspect of the present invention, when the second determination unit determines that the free space in the third storage unit is smaller than the predetermined capacity, the deletion unit stores the date stored in the fourth storage unit. The information is deleted from the third storage unit in preference to the motion data corresponding to the date information that is a date away from the current date and time. Therefore, the motion data that has an old date of use and is unlikely to be acquired again via the network is deleted. As a result, the storage capacity of the storage unit that stores motion data can be used efficiently, and the distribution efficiency of motion data can be reduced without reducing network bandwidth or extending the distribution time due to an increase in data volume. Can be raised.

  According to the fifth aspect of the present invention, when the second determination unit determines that the free capacity of the third storage unit is smaller than the predetermined capacity, the deletion unit uses the usage stored in the fifth storage unit. From the number of times information, the motion data with the smaller number of times of use is prioritized and deleted from the third storage unit. Accordingly, motion data that is used less frequently and is less likely to be acquired again via the network is deleted. As a result, the storage capacity of the storage unit that stores motion data can be used efficiently, and the distribution efficiency of motion data can be reduced without reducing network bandwidth or extending the distribution time due to an increase in data volume. Can be raised.

  According to the sixth aspect of the present invention, the generation unit includes a main motion that is the main motion motion and a motion motion that has a smaller motion load than the main motion, and before performing the main motion. 1st identification information which discriminate | determines from the warming-up exercise | movement performed in 1). When the second determination unit determines that the information amount stored in the third storage unit is larger than the predetermined information amount, the deletion unit selects the main motion data stored in the third storage unit from the main motion data. The motion data corresponding to the first identification information for identifying the exercise is deleted preferentially. In general, the exercise operation is performed by continuously performing a warm-up exercise and a main exercise. The main movement is composed of various types of movement. On the other hand, the warm-up exercise is composed of several predetermined types of exercise operations with a small exercise load. Therefore, the warm-up exercise is an exercise operation that is frequently used although there are few types of exercise operation. On the other hand, the main exercise is an exercise operation that is less frequently used as exercise content, although it has more types of exercise operation than the warm-up exercise. As a result, motion data with a relatively low use frequency is deleted. As a result, the storage capacity of the storage unit that stores motion data can be used efficiently, and the distribution efficiency of motion data can be reduced without reducing network bandwidth or extending the distribution time due to an increase in data volume. Can be raised.

  According to the seventh aspect of the present invention, the generation unit is a main motion that is the main of the motion motion, and a motion motion that has a smaller motion load than the main motion, and has performed the main motion. First identification information for identifying a cool-down exercise to be performed later is included. When the second determination unit determines that the information amount stored in the third storage unit is larger than the predetermined information amount, the deletion unit selects the main motion data stored in the third storage unit from the main motion data. The motion data corresponding to the first identification information for identifying the exercise is deleted preferentially. In general, the exercise operation is performed by continuously performing a cool-down exercise and a main exercise. The main movement is composed of various types of movement. On the other hand, the cool-down exercise is composed of several types of predetermined exercise operations with a small exercise load. Accordingly, the cool-down exercise is an exercise operation that is frequently used although there are few types of exercise operation. On the other hand, the main exercise has more types of exercise motion than the cool-down exercise, but is an exercise motion that is less frequently used as exercise content. As a result, motion data with a relatively low use frequency is deleted. As a result, the storage capacity of the storage unit that stores motion data can be used efficiently, and the distribution efficiency of motion data can be reduced without reducing network bandwidth or extending the distribution time due to an increase in data volume. Can be raised.

  According to the eighth aspect of the present invention, when the first determination unit determines that there is motion data that is not stored in the third storage unit, the requesting unit is a motion that is not stored in the third storage unit. The information processing is requested to acquire data. Accordingly, there is no need to request motion data already stored in duplicate. As a result, the distribution efficiency of motion data can be improved without causing the network band to be compressed or the distribution time to be increased due to an increase in the amount of data.

  According to the ninth and tenth aspects of the present invention, when it is determined by the first determination step that there is motion data not stored in the third storage unit, the request step is stored in the third storage unit. Requests information processing to acquire motion data that has not been processed. Accordingly, there is no need to request motion data already stored in duplicate. As a result, the distribution efficiency of motion data can be improved without causing the network band to be compressed or the distribution time to be increased due to an increase in the amount of data.

[Best Embodiment]
An embodiment in which the present invention is applied to a content distribution system for distributing exercise content will be described with reference to the drawings.

<Configuration of content distribution system of this embodiment>
FIG. 1 is a configuration diagram of a content distribution system 100 according to this embodiment to which the present invention is applied. The content distribution system 100 includes a terminal device 1 and a distribution server 10. The terminal device 1 and the distribution server 10 are connected via the Internet. The terminal device 1 outputs the content acquired from the distribution server 10. In the present embodiment, athletic content including three-dimensional CG is distributed from the distribution server 10 to the terminal device 1 as content. The distribution server 10 of this embodiment is an example of an information processing apparatus of the present invention. Moreover, the terminal device 1 of this embodiment is an example of the terminal device of this invention.

<External configuration of the terminal device 1 of the present embodiment>
FIG. 2 is an external view of the terminal device 1 according to this embodiment to which the present invention is applied. The terminal device 1 includes a speaker 2, a speaker 3, a display 4, and an information input unit 5. The display 4 displays an exercise image 160. When the motion video 160 is displayed on the display 4, the music output together with the motion video 160 is output by the speakers 2 and 3. Using the information input unit 5, the user inputs information for selecting exercise and information for selecting music. For example, the information input unit 5 is a keyboard or a mouse. As shown in FIG. 2, the user 150 can perform exercise by viewing the exercise image 160 displayed on the display 4.

<Electrical Configuration of Distribution Server 10 of this Embodiment>
FIG. 3 is a block diagram showing an electrical configuration of the distribution server 10 of the present embodiment. As shown in FIG. 3, the distribution server 10 of this embodiment includes a CPU 11 that controls the distribution server 10. The CPU 11 is electrically connected to the HDD 12, the RAM 13, and the network connection unit 14. The CPU 11 constitutes a computer that controls the operation of the distribution server 10 together with storage means such as the HDD 12 and the RAM 13. The network connection unit 14 communicates information with the terminal device 1 via the Internet.

  The HDD 12 includes a first identification information storage area 121, a first motion data storage area 122, a first lesson information storage area 123, and a distribution server program information storage area 124.

  FIG. 4 is a conceptual diagram showing a storage state in which identification information is stored in the first identification information storage area 121. The first identification information storage area 121 stores a plurality of identification information. The identification information is information for identifying specific exercise motion content. As shown in FIG. 4, the first identification information storage area 121 stores “half squat”, “quarter squat”, “march”,. . In addition, the code which identifies each exercise | movement action may be memorize | stored as identification information.

  The first identification information storage area 121 stores appearance type information associated with each identification information. The appearance type information indicates a position where the motion motion represented by the identification information appears. The exercise content is generated by combining a plurality of exercise operations. General exercise content includes a warm-up exercise, a main exercise, and a cool-down exercise. The exercise content is executed in the order of “warming up”, “main exercise”, and “cool down”. In other words, the appearance type information is information indicating whether the exercise operation to be performed can be used in “warming up”, “main exercise”, or “cool down”. The warm-up exercise is an exercise to loosen the body that is performed when the exercise is started. Compared to the main exercise, the exercise is less intense or less intense. The main exercise is an exercise executed as a main exercise operation when exercise is performed. The cool-down exercise is an exercise that is performed at the end of the exercise, and is an exercise that is less intense or less intense than the main exercise. The cool-down exercise is an exercise that loosens the body by stretching the body. In FIG. 4, the appearance type information corresponding to the identification information “half squat” is “warming up or main exercise”. This indicates that “half squats” are available for “warming up” or “main exercise”.

  In the first identification information storage area 121, exercise type information is stored in association with each identification information. The exercise type information is information representing the type of exercise motion represented by each piece of identification information. Specifically, the exercise type information is information indicating the type of exercise represented by “aerobic exercise”, “anaerobic exercise”, and “stretch exercise”. Detailed description of the exercise type information will be described later.

  The first identification information storage area 121 stores data size information in association with each identification information. The data size information indicates the data amount of motion data corresponding to each identification information. Details of the motion data will be described later. For example, the data size information corresponding to the identification information “half squat” is “60 MB”. This indicates that the data size information of the motion data corresponding to the identification information “half squat” is 60 MegaByte.

  Specifically, aerobic exercise includes step exercise. The step exercise can be executed as an effective aerobic exercise by being executed at an appropriate exercise tempo for each user. The step exercise is an exercise mainly using the legs and repeating the same pattern for a certain period. Effective aerobic exercise is exercise that can continue without undue fatigue while taking oxygen into the body (eg, step exercise and jogging). Aerobic exercise is exercise that exceeds the minimum exercise intensity at which fat is easily combusted. When the tempo is below an appropriate tempo, for example, when the tempo is slow, the exercise intensity is weak, and the effect as an aerobic exercise may not be obtained. Further, even when the tempo is higher than the appropriate tempo, for example, when the tempo is fast, there is a possibility that the exercise intensity is strong and the effect as an aerobic exercise does not appear and an anaerobic exercise is caused. In this case, the user feels excessive fatigue, and not only cannot continue the exercise for a long time, but also may not obtain the effect as an aerobic exercise. In the present embodiment, an exercise tempo (Beat Per Minutes: BPM) can be set for each piece of identification information. Therefore, it is possible to cause each user to execute a step exercise at an appropriate exercise tempo. Therefore, the step exercise can be executed as an aerobic exercise at an appropriate exercise tempo for each user. “March”, “front lunge”, “back lunge”, “side step” and the like shown in FIG. 4 are examples of the step motion.

  Moreover, specifically, anaerobic exercise includes strength training exercise. The strength training exercise can be switched between a strength training exercise for applying endurance and a strength training exercise for applying instantaneous force by changing the exercise tempo for executing the strength training. The exercise tempo is changed for each user depending on the purpose of strength training, such as whether to apply endurance or instantaneous power. By changing the exercise tempo, the strength training exercise can change the purpose of the strength training. The strength training exercise using a barbell such as “shoulder press” or “chest press” shown in FIG. 4 is an example of the strength training exercise. 4 is an example of a strength training exercise using legs.

  The stretching exercise is an exercise for stretching each body part of a person. There are stretching exercises associated with each body part of a person, such as “upper arm stretching” and “neck stretching” shown in FIG. Stretching exercises include yoga. Yoga is an exercise that stretches the body by holding a variety of poses by the human body.

  The first motion data storage area 122 stores motion data. The motion data is an image representing a motion motion corresponding to each identification information. FIG. 5 is a conceptual diagram showing a storage state in which motion data is stored in the first motion data storage area 122. As shown in FIG. 5, “March video” is stored in the first motion data storage area 122 as motion data corresponding to the identification information “March”. Similarly, “front lunge video” is stored in the first motion data storage area 122 as motion data corresponding to the identification information “front lunge”. The motion data storage area 122 of this embodiment is an example of the first storage unit of the present invention.

  Next, FIG. 6 is an explanatory diagram for explaining the details of the motion data used in the present embodiment. In the present embodiment, as shown in FIG. 6, a figure A representing a human figure is displayed on the display 4 by three-dimensional CG (Computer Graphics). When the figure A performs a predetermined exercise operation, an exercise image 160 shown in FIG. 2 is displayed. Hereinafter, the details of the motion image 160 used in the present embodiment will be described with reference to FIG.

  First, in order to display the figure A by the three-dimensional CG, the three-dimensional virtual space 60 is secured in a predetermined storage area of the terminal device 1 or a predetermined storage area of the distribution server according to a program. The three-dimensional virtual space 60 of this embodiment is defined as coordinate data based on the XYZ coordinate axes 65. Specifically, the figure A or the like arranged in the three-dimensional virtual space 60 is defined as coordinate data based on the XYZ coordinate axes 65.

  Further, various “●” (black circles in the figure) installed in the three-dimensional virtual space 60 are viewpoints for displaying the figure A on the display 4. The viewpoints are arranged at 24 fixed positions shown in FIG. A virtual camera is arranged at each viewpoint. An image captured by the virtual camera is displayed on the display 4 so that an exercise image 160 is displayed. A predetermined shooting direction 62 (gaze direction) and angle of view (vertical angle of view θ1, horizontal angle of view θ2) are set in the virtual camera. The number of viewpoints arranged in the three-dimensional virtual space 60 is an example. The number of viewpoints can be arbitrarily increased or decreased. In the present embodiment, it is assumed that a captured video is displayed on the display 4 from the virtual camera 61 arranged at a predetermined viewpoint.

  Fig.7 (a) is a conceptual diagram which shows the coordinate position of each body part of the person which the figure A shown in FIG. 5 represents. The figure A is generated based on the coordinate position of each body part shown in FIG. P1 to P17 in FIG. 7A represent the body parts of the figure A. FIG. 7B is an explanatory diagram showing the coordinate positions of P1 to P17 representing each body part of FIG. 7A in order to display one predetermined motion of the figure A. A plurality of videos representing the coordinate positions shown in FIG. 7B are continuously displayed on the display 4, so that a video of a person performing a predetermined exercise is displayed on the display 4.

  Here, a process of photographing the inside of the three-dimensional virtual space 60 with a virtual camera and generating a two-dimensional image will be briefly described. In the present embodiment, the process of converting the figure A arranged in the three-dimensional virtual space 60 into a two-dimensional image is performed by a series of coordinate conversion processes based on affine transformation. The 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 the affine transformation, coordinates (for example, local coordinates) set for each object arranged in the three-dimensional virtual space 60 are sequentially converted into world coordinates, view coordinates, screen coordinates, and device coordinates to obtain two. Dimensional coordinates can be used. Thereby, an image in which the object is viewed from the viewpoint can be generated. Specific processing of coordinate transformation by this affine transformation is known. Hereinafter, an outline of a series of processes until the local coordinates of the figure A arranged in the three-dimensional virtual space 60 are converted into device coordinates will be described.

  As shown in FIG. 8, the figure A includes coordinate data based on XYZ coordinate axes 65, which are important body parts (indicated by black circles in the figure) such as the head, chest, right hand, left hand, and various legs. Is defined as The coordinates of each of these body parts are defined by XYZ coordinate axes 65, respectively. The details of the body are further defined by coordinate data based on each of these body parts, and the texture mapping technique expressed by known texture mapping or the like is a known technique. For the sake of simplification, detailed description is omitted.

  The coordinates of the XYZ coordinate axis 65 (world coordinate system) defining the three-dimensional virtual space 60 are converted into the coordinates of the view coordinate system 66 with the position coordinate of the viewpoint position of the virtual camera 61 as the origin. Then, a planar virtual screen 68 is defined in the three-dimensional virtual space 60 defined as the coordinates of the view coordinate system 66. Then, an image of the figure A seen through the virtual screen 68 from the virtual camera 61 is formed on the virtual screen 68. Specifically, in the view coordinate system 66, a virtual line (indicated by a one-dot chain line in the figure) connecting the virtual camera 61 and each body part of the figure A intersects the virtual screen 68 with respect to the coordinates of each body part of the figure A. Convert to point coordinates (screen coordinates).

  The coordinates of each body part of the figure A thus converted into the coordinates on the virtual screen 68 are still defined as three-dimensional coordinates in the view coordinate system 66 at this point, and are then converted to the coordinates of the two-dimensional plane. Convert to The coordinates (device coordinates) on the two-dimensional virtual screen 69 indicated by the device coordinate system 67 having a size for displaying the coordinates (screen coordinates) on the virtual screen 68 indicated by the view coordinate system 66 on the display 4 described above. Convert to

  With the above affine transformation, an image in which the figure A is projected on the virtual screen 68 viewed from the viewpoint arranged in the three-dimensional virtual space 60 can be obtained. An image acquired by the affine transformation is displayed on the display 4 as a motion image 160.

In the example of FIG. 10, the distribution status information of the lesson information “L1” corresponding to the terminal device information “A1” is “Done”. This indicates that the lesson information “L1” has already been distributed to the terminal device “A1”. On the other hand, the delivery status information of the lesson information “L5” corresponding to the terminal device information “A2” is “not delivered”. This indicates that the lesson information “L5” is not distributed to the terminal device “A2”. If the distribution server 10 tries to distribute the newly registered lesson information to the terminal device A2, but cannot be distributed because the power of the terminal device A2 is turned off, “undistributed” is registered. Is done.

  The RAM 13 includes an unstored identification information temporary storage area 131. The unstored identification information temporary storage area 131 temporarily stores unstored identification information. Unstored identification information is identification information corresponding to motion data that is not stored in the terminal device 1 in lesson information distributed by the distribution server 10. When the distribution server 10 distributes new lesson information to the terminal device 1, the terminal device 1 determines whether motion data corresponding to the identification information included in the lesson information is stored in the storage unit of the terminal device 1. As a result of the determination, when it is determined that there is motion data corresponding to the identification information not stored in the terminal device 1 among the identification information included in the lesson information, the terminal device 1 is determined not to be stored. The identification information is transmitted to the distribution server 10.

Step S101 is repeated until it is determined that the power switch is turned on. The power switch may be a hardware switch or a power switch operated by software. When it is determined in step S101 that the power switch is turned on (step S101: YES), step S102 is executed.

  In step S102, it is determined whether or not there is a connection request from the distribution server 10 to the terminal device 1. The connection request from the distribution server 10 to the terminal device 1 is transmitted from the distribution server 10 to the terminal device 1 when new lesson information is distributed from the distribution server 10. When it is determined that there is a connection request from the distribution server 10 to the terminal device 1 (step S102: YES), step S103 is executed. When it is determined that there is no connection request from the distribution server 10 to the terminal device 1 (step S102: NO), step S113 is executed.

  In step S103, lesson information newly distributed from the distribution server 10 to the terminal device 1 is acquired. Specifically, the new lesson information transmitted from the distribution server 10 is received by the terminal device 1.

  In step S113, it is determined whether the power switch is turned off by the user. If the power switch is not turned off (step S113: NO), step S102 is executed again. When the power switch is turned off (step S113: YES), the process returns to step S101 and step S101 is executed again.

(Delete processing)
FIG. 15 is a flowchart for executing the deletion process of the terminal device 1 according to the deletion process program. First, in step S201, a deletion candidate list is generated. In step S201, all the identification information stored in the second identification information storage area 72 is acquired first. From the acquired identification information, identification information other than the identification information included in the new lesson information received in step S103 is determined. The determined identification information is determined as identification information constituting the deletion candidate list.

  In step S202, it is determined whether or not there is a predetermined number or more of identification information that can be used for the warm-up exercise in the deletion candidate list generated in step S201. Whether or not the exercise can be used for the warm-up exercise is determined based on the appearance type information stored in the second identification information storage area 72. Based on the appearance type information stored in the second identification information storage area 72, it is determined whether or not the identification information included in the deletion candidate list can be used for the warm-up exercise. As a result of the determination, when the number of pieces of identification information that can be used for the warm-up exercise is a predetermined number or more (step S202: YES), step S204 is executed. When it is determined that the number of pieces of identification information that can be used for the warm-up exercise is not a predetermined number or more (step S202: NO), step S203 is executed. In step S202 of the present embodiment, it is determined whether or not the number of pieces of identification information that can be used for the warm-up exercise is a predetermined number or more. The total number of identification information included in the deletion candidate list may be compared with the number of identification information that can be used for the warm-up exercise. A ratio between the total number of identification information and the number of identification information that can be used for the warm-up exercise may be determined, and it may be determined whether the ratio is equal to or greater than a predetermined value. The computer of this embodiment and step S202 are an example of the second determination unit of the present invention.

  In step S203, identification information that can be used for the warm-up exercise in the deletion candidate list is excluded from the deletion target. Specifically, identification information that can be used for the warm-up exercise is deleted from the deletion candidate list. The computer of this embodiment and step S203 are an example of the deletion unit of the present invention.

  In step S204, it is determined whether or not there is a predetermined number or more of identification information that can be used for the cool-down exercise in the deletion candidate list generated in step S201. Whether or not the exercise can be used for the cool-down exercise is determined based on the appearance type information stored in the second identification information storage area 72. Based on the appearance type information stored in the second identification information storage area 72, it is determined whether or not the identification information included in the deletion candidate list can be used for the cool-down exercise. As a result of the determination, when the number of pieces of identification information that can be used for the cool-down exercise is a predetermined number or more (step S204: YES), step S206 is executed. When it is determined that the number of pieces of identification information that can be used for the cool-down exercise is not a predetermined number or more (step S204: NO), step S205 is executed. In step S204 of the present embodiment, it is determined whether or not the number of pieces of identification information that can be used for the cool-down exercise is a predetermined number or more. The total number of identification information items included in the deletion candidate list may be compared with the number of identification information items that can be used for the cool-down exercise. A ratio between the total number of identification information and the number of identification information that can be used for the cool-down exercise may be determined, and it may be determined whether the ratio is equal to or greater than a predetermined value. The computer of this embodiment and step S202 are an example of the second determination unit of the present invention.

  In step S205, identification information that can be used for the cool-down exercise in the deletion candidate list is excluded from the deletion target. Specifically, identification information that can be used for the cool-down exercise is deleted from the deletion candidate list. The computer of this embodiment and step S203 are an example of the deletion unit of the present invention.

  In step S206, the motion data corresponding to the identification information with the oldest usage date is deleted from the second motion data storage area 72 from the deletion candidate list. The last used date information stored in the second identification information storage area 72 is referred to in order to determine the oldest used identification information from the identification information included in the deletion candidate list. Last use date information corresponding to the identification information included in the deletion candidate list is extracted from the second identification information storage area 72. The identification information having the oldest extracted last use date from the present time is determined. The motion data corresponding to the identification information whose determined last use date is the oldest from the present time is deleted from the second motion data storage area 72. Note that date information representing the current date is acquired from the Internet via the network connection unit 9. Although not shown, a current time may be acquired by providing a timer for measuring time in the CPU. Further, not only the current date but also information indicating the current time may be acquired. In step S206, a predetermined number of pieces of identification information may be selected in order from the oldest use date and deleted from the second motion data storage area 72.

  In step S207, it is determined whether or not an empty capacity corresponding to the total data capacity has been generated in the second motion data storage area 72 by deleting the motion data in step S206. For the value of the total data capacity, the value stored in the data capacity information temporary storage area 81 is referred to. When it is determined that a free capacity capable of storing the total data capacity has been generated (step S207: YES), the deletion process is terminated. On the other hand, when it is not determined that a free capacity capable of storing the total data capacity has been generated (step S207: NO), step S206 is executed again. Steps S206 and S207 are repeatedly executed until the total data capacity can be stored.

<Description of Operation of Distribution Server 10 of this Embodiment>
The operation and action of the distribution server 10 of this embodiment will be described with reference to the accompanying drawings. First, operation | movement and an effect | action of the delivery server 10 are demonstrated with reference to an accompanying drawing. FIG. 16 is a flowchart illustrating a processing procedure of the main operation in the distribution server 10. The main operation is performed by the CPU 11 executing the main operation program when an external power source such as a commercial power source is connected to the distribution server 10 via a power source or an outlet. The processing shown below is processed by the CPU 11.

  In the distribution server 10, it is first determined in step S301 whether or not the power switch of the apparatus has been turned on by the user. Step S301 is repeated until it is determined that the power switch is turned on. The power switch may be a hardware switch or a power switch operated by software. When it is determined in step S301 that the power switch is turned on (step S301: YES), step S302 is executed.

  In step S302, it is determined whether there is a request for distribution of new lesson information. The request for distribution of new lesson information is made by an input unit (not shown) by the content provider or the user of the distribution server 10. When it is determined that there is a request for distribution of new lesson information (step S302: YES), step S303 is executed. When it is not determined that there has been a request for distribution of new lesson information (step S302: NO), step S304 is executed.

  In step S303, distribution of new lesson information is started. First, new lesson information is stored in the first lesson information storage area 123 by the content provider or the user of the distribution server 10. In addition, identification information included in the new lesson information is stored in the first identification information storage area 121. At this time, the delivery status information corresponding to the new lesson information is stored as “undelivered”. Motion data corresponding to the identification information stored in the first identification information storage area 121 is stored in the first motion data storage area 122. Then, the lesson information newly stored in the first lesson information storage area 123 is distributed to the terminal device 1. The computer of this embodiment and step S303 are an example of the 1st transmission part of this invention. Moreover, step S303 of the present embodiment is an example of a first transmission step of the present invention.

  In step S304, it is determined whether there is a terminal device 1 to which new lesson information has not been distributed. Based on the distribution status information stored in the first lesson information storage area 123, it is determined whether there is a terminal device 1 to which new lesson information has not been distributed. Specifically, it is determined whether or not there is a terminal device 1 in which the newly distributed lesson information has not been distributed among the lesson information stored in the first lesson information storage area 123. In the example of FIG. 10, it is assumed that lesson information “L5” is newly distributed. In this case, the delivery status information corresponding to the lesson information “L5” of the terminal device A1 is “not delivered”. Similarly, the delivery status information corresponding to the lesson information “L5” of the terminal device A2 and the terminal device A3 is “not delivered”. If at least one piece of distribution status information corresponding to newly distributed lesson information is “undelivered”, it is determined that there is a terminal device 1 for which new lesson information has not been distributed. If there is no distribution status information corresponding to newly distributed lesson information that is not “undistributed”, it is determined that there is no terminal device 1 to which new lesson information is not distributed. When it is determined that there is a terminal device 1 to which new lesson information has not been distributed (step S304: YES), step S305 is executed. When it is determined that there is no terminal device to which new lesson information has not been distributed (step S304: NO), step S316 is executed.

  In step S305, the undelivered terminal device 1 is determined based on the information stored in the first lesson information storage area 123. Specifically, the terminal device 1 whose distribution status information corresponding to newly distributed lesson information is “undistributed” is determined. In the example of FIG. 10, the terminal device A1, the terminal device A2, and the terminal device A3 whose distribution status information corresponding to the lesson information “L5” is “undelivered” are determined.

  In step S306, a connection to the terminal device 1 determined in step S305 is requested. Specifically, the connection information stored in the first lesson information storage area 123 is referred to. The connection information of the terminal device 1 determined in step S302 is referred to, and a connection is requested from the distribution server 10 to the terminal device 1.

  In step S307, it is determined whether or not the connection to the terminal device 1 requested in step S306 is successful. The terminal device 1 that has received the connection request transmits a message indicating that the connection is successful to the distribution server 10. By receiving the message, the distribution server 10 can grasp that the connection to the terminal device 1 has been requested. When it is determined that the connection request to the terminal device 1 is successful (step S307: YES), step S308 is executed. When it is not determined that the connection request to the terminal device 1 is successful, step S316 is executed. In step S307, it may be determined whether a message has been received from the terminal device 1 within a predetermined period.

  In step S308, undelivered lesson information is distributed to the terminal device 1 determined to have been successfully connected in step S307. In the example of FIG. 10, the terminal device A1, the terminal device A2, and the terminal device A3 have the distribution status information corresponding to the lesson information “L5” “undelivered”. When the connection with the terminal device A1 is successful in step S307, the distribution server 10 distributes the lesson information “L5” to the terminal device A1. The computer of this embodiment and step S308 are an example of the first transmission unit of the present invention. Step S308 of the present embodiment is an example of the first transmission step of the present invention.

  In step S309, it is determined whether or not a processing completion message transmitted by the terminal device 1 has been received. The processing completion message is a message indicating that the terminal device 1 has completed the acquisition of motion data related to the lesson information transmitted in step S308. When it is determined that the process completion message has been received (step S309: YES), step S316 is executed. When it is not determined that the process completion message has been received (step S309: NO), step S310 is executed.

  In step S310, it is determined whether a request for motion data corresponding to unstored identification information has been received. A request for motion data corresponding to unstored identification information is transmitted from the terminal device 1 to the distribution server 10. When it is determined that a request for motion data corresponding to unstored identification information has been received (step S310: YES), step S311 is executed. When it is determined that a request for motion data corresponding to unstored identification information has been received (step S310: NO), step S309 is executed.

  In step S311, the unstored identification information received in step S310 is temporarily stored in the unstored identification information temporary storage area 131.

  In step S <b> 312, the total capacity of motion data corresponding to the unstored identification information stored in step S <b> 311 is transmitted to the terminal device 1. First, the total data capacity of motion data corresponding to unstored identification information stored in the unstored identification information temporary storage area 131 is determined. The total data capacity is determined based on data size information stored in the first identification information storage area 121. Identification information corresponding to the unstored identification information is determined from the first identification information storage area 121. Data size information corresponding to the determined identification information is referred to. The sum of the referenced data size information is determined as the total data capacity. The determined total data capacity is transmitted to the terminal device.

  In step S313, it is determined whether a request to start transmission of motion data is received from the terminal device 1. Specifically, the terminal device 1 requests the start of transmission of motion data corresponding to unstored identification information. The terminal device 1 requests the distribution server 10 to transmit motion data. When it is determined by the terminal device 1 that transmission of motion data has been requested (step S313: YES), step S314 is executed. When it is not determined that the transmission of motion data is requested by the terminal device 1 (step S313: NO), step S313 is repeatedly executed.

  In step S314, motion data corresponding to the unstored identification information is transmitted to the terminal device 1. Motion data corresponding to the unstored identification information is read from the first motion data storage area 122 and transmitted to the terminal device 1. The computer of this embodiment and step S314 are an example of the 2nd transmission part of this invention. Moreover, step S314 of this embodiment is an example of the 2nd transmission step of this invention.

  In step S315, it is determined whether a reception completion message has been received. The reception completion message is a message indicating that the transmission of the motion data transmitted in step S314 has been completed. The reception completion message is transmitted from the terminal device 1 to the distribution server 10. When it is determined that the reception completion message has been received (step S315: YES), step S316 is executed. When it is not determined that the reception completion message has been received (step S315: NO), step S315 is repeatedly executed.

  In step S316, it is determined whether the power switch is turned off by the user. If the power switch is not turned off, step S302 is executed again. When the power switch is turned off, the process returns to step S301 and step S301 is executed again.

(Modification 1)
A modification of this embodiment will be described with reference to FIG. FIG. 17 shows a modification of the deletion process of this embodiment.

  The process in step S401 is the same as the process in step S201.

  In step S402, it is determined whether or not the deletion candidate list generated in step S401 includes identification information acquired within a predetermined period from the current time. Specifically, the acquisition date information stored in the second identification information storage area 72 is referred to. Acquisition date information corresponding to the identification information included in the deletion candidate list is extracted. In the extracted acquisition date information, it is determined whether there is identification information acquired within a predetermined period from the current time. Specifically, the predetermined period is one month. The purpose of this determination process is to exclude recently acquired motion data from deletion candidates because the terminal device 1 is likely to be used. When it is determined that there is identification information acquired within a predetermined period from the current time (step S402: YES), step S403 is executed. When it is not determined that there is identification information acquired within a predetermined period from the current time (step S402: NO), step S404 is executed. The computer of this embodiment and step S402 are an example of the second determination unit of the present invention.

  In step S403, identification information acquired within a predetermined period from the current time in the deletion candidate list is excluded from deletion targets. Specifically, the identification information acquired within a predetermined period from the current time is deleted from the deletion candidate list. The computer of this embodiment and step S403 are examples of the deletion unit of the present invention.

  In step S404, the motion data corresponding to the identification information with the smallest number of uses is deleted from the second motion data storage area 72 from the deletion candidate list. The number-of-uses information stored in the second identification information storage area 72 is referred to in order to determine the identification information with the smallest number of times of use from the identification information included in the deletion candidate list. The number-of-uses information corresponding to the identification information included in the deletion candidate list is extracted from the second identification information storage area 72. The identification information with the smallest extracted number-of-uses information is determined. Motion data corresponding to the determined identification information is deleted from the second motion data storage area 72. In step S404, a predetermined number of pieces of identification information may be selected in order from the least used one and deleted from the second motion data storage area 72.

  In step S405, it is determined whether or not an empty capacity corresponding to the total data capacity has been generated in the second motion data storage area 72 by deleting the motion data in step S404. When it is determined that a free capacity capable of storing the total data capacity has been generated (step S405: YES), the deletion process is terminated. On the other hand, when it is not determined that a free capacity capable of storing the total data capacity has been generated (step S405: NO), step S404 is executed again. Steps S404 and S405 are repeatedly executed until the total data capacity can be stored.

  As the deletion process, the terminal device 1 may compare the second motion data storage area 72 and the second lesson information storage area 74. In this case, among the motion data stored in the second motion data storage area 72, motion data corresponding to identification information that is not stored in the second lesson information storage area 74 is determined. The determined motion data may be deleted from the second motion data storage area 72. This is because motion data that is not stored in the second lesson information storage area 74 is not used by the terminal device 1. The unused capacity may be generated by deleting motion data that is not used from the second motion data storage area 72. In addition, a predetermined number of motion data may be deleted from the second motion data storage area 72 in preference to the motion data corresponding to the identification information not stored in the second lesson information storage area 74. In addition, the motion data corresponding to the identification information not stored in the second lesson information storage area 74 may be deleted one by one, and the determination process in step S108 may be executed. The motion corresponding to the identification information not stored in the second lesson information storage area 74 until it is determined in the determination process of step S108 that the storage capacity capable of storing motion data is in the second motion data storage area 73. Data may be deleted one by one.
