Summary of the Invention

Problems to be Solved by the Invention

[0004] When a user trains using an electrical stimulation device in a personal place such as home, there may be cases where the user does not know how to use the electrical stimulation device or an effective training method, and problems such as not being able to obtain a sufficient training effect or not being able to maintain the motivation to continue training may occur. Also, although it is conceivable to go to a store such as a fitness gym and receive instruction from an instructor, it may not be realistic for users who do not have such a store nearby.

[0005] The present invention has been made in view of such circumstances, and an object thereof is to provide an electrical stimulation training information transmission device or the like that can effectively train even remote users.

Means for Solving the Problems

[0006] To solve the above problems, an electrical stimulation training information transmission device according to one aspect of the present invention comprises: a video data providing unit that provides video data for the user to view during training; an electrical stimulation instruction data providing unit that provides instruction data for electrical stimulation to be applied by an electrical stimulation device worn by the user during training; a synchronization signal generating unit that generates a synchronization signal for synchronizing the video data and the instruction data; and a transmission unit that transmits the video data and the synchronization signal.

[0007] In this configuration, users can effectively perform training accompanied by electrical stimulation while watching received video. The video can be anything, but for example, if a video of an instructor demonstrating the training is played, the user can effectively train by following along. At this time, the combination of video and electrical stimulation synchronized by a received synchronization signal enhances immersion in the training and results in superior training effects.

[0008] Another aspect of the present invention is an electrical stimulation training information receiving device. This device comprises a receiving unit that receives video data viewed by the user during training and a synchronization signal for synchronizing the video data with instruction data for electrical stimulation provided by an electrical stimulation device worn by the user during training, and a data synchronization unit that synchronizes the video data and instruction data based on the synchronization signal.

[0009] A further aspect of the present invention is an electrical stimulation training information communication device. This device comprises a video data providing unit that provides video data for the user to view during training; an electrical stimulation instruction data providing unit that provides instruction data for electrical stimulation to be applied by an electrical stimulation device worn by the user during training; a synchronization signal generating unit that generates a synchronization signal for synchronizing the video data and the instruction data; a transmitting unit that transmits the video data and the synchronization signal; a receiving unit that receives the video data and the synchronization signal; and a data synchronization unit that synchronizes the video data and the instruction data based on the synchronization signal.

[0010] A further aspect of the present invention is an electrical stimulation training information communication method. This method comprises a video data provision step of providing video data to be viewed by the user during training; an electrical stimulation instruction data provision step of providing instruction data for electrical stimulation to be applied by an electrical stimulation device worn by the user during training; a synchronization signal generation step of generating a synchronization signal for synchronizing the video data and the instruction data; a transmission step of transmitting the video data and the synchronization signal; a reception step of receiving the video data and the synchronization signal; and a data synchronization step of synchronizing the video data and the instruction data based on the synchronization signal.

[0011] Furthermore, any combination of the above components, as well as conversions of the expression of the present invention between methods, apparatus, systems, recording media, computer programs, etc., are also valid embodiments of the present invention. [Effects of the Invention]

[Modes for carrying out the invention]

[0014] The following describes an example of an embodiment of the present invention. Identical or equivalent components are denoted by the same reference numerals, and redundant descriptions are omitted. In each drawing, for the sake of clarity, some components are omitted as appropriate, and their dimensions are enlarged or reduced as appropriate. Directions such as up, down, left, and right in each drawing are described based on the orientation of the reference numerals in that drawing. Furthermore, terms such as "applying," "contacting," "fixing," and "attaching" that describe the relationship between two components include cases where the two components directly satisfy the conditions being referred to, as well as cases where the conditions are satisfied through other components, unless otherwise specified.

[0015] Figure 1 schematically shows the configuration of an exercise control system in which the electrical stimulation training information communication device according to the embodiment is realized. The exercise control system 100 executes a predetermined training program 2 under the supervision of a director using the director terminal 12e, and local or remote users using user terminals 12a, 12b, and 12c respectively perform training that involves applying electrical stimulation to the muscles while receiving demonstration guidance from an instructor using the instructor terminal 12d. In this figure, for simplicity, two users training at a fitness gym 80, which serves as a store where the instructor provides demonstration guidance, and one user training remotely from a personal space 81 such as a home, but a larger number of users can train simultaneously. At the fitness gym 80, the number of users can be increased up to the maximum number of people that can train according to the space, and at the personal space 81, the number of users can be increased within a range that does not exceed the processing capacity of the information communication network and information processing server described later. For example, hundreds to thousands (or even more) of users can participate in training simultaneously. In this way, a large number of users simultaneously participate in a high-quality training program 2 that combines video, audio, and electrical stimulation, creating a sense of unity with the instructor and other users, a feeling of exhilaration during training, and a sense of immersion in the training, thereby achieving high training effectiveness.

[0016] Next, the components of the motion control system 100 shown in Figure 1 will be described in order. User terminals 12a, 12b, and 12c (hereinafter collectively referred to as user terminals 12; the subscripts a, b, and c indicating the user will be omitted as appropriate for user terminals 12 and other components) are equipped with a display screen 13, a speaker 14, and an operation unit 15.

[0017] The display screen 13 shows the video that the user sees during training. Details of the video will be described later, but for example, it can combine pre-prepared videos in training program 2, live video from fitness gym 80 (video of the demonstrating instructor, video of the user during training, etc.), and videos inserted by the director as needed. In addition, the video displayed may be different for on-site users in fitness gym 80 and remote users in personal space 81. For example, for a user receiving demonstration instruction from an instructor in front of them at fitness gym 80, it is not necessary to display the instructor's video (live video of the instructor 831 in Figures 17(A) and 18(A)) on the display screen 13; rather, a simpler display can encourage the user to focus their attention on the instructor in front of them rather than the display screen 13. On the other hand, for remote users in personal space 81, the live video from fitness gym 80 is extremely effective in providing a sense of presence as if they were actually at fitness gym 80 during training. Note that instead of providing individual display screens 13 for each user in fitness gym 80, a common screen may be provided in the training space.

[0018] Speaker 14 plays audio for the user during training. Details of the audio will be described later, but for example, it can be a combination of music such as pre-prepared background music during training program 2, live audio from fitness gym 80 (such as the instructor's instructions and the user's voice during training), and audio inserted by the director as needed. In addition, the audio played may be different for on-site users in fitness gym 80 and remote users in personal space 81. For example, users who can directly hear the live audio from fitness gym 80 do not need to play the live audio from speaker 14, so in some cases, speaker 14 may not be provided on the user terminal 12. On the other hand, for remote users in personal space 81, the live audio from fitness gym 80 is extremely effective in providing a sense of presence as if they were actually in fitness gym 80 during training. Note that instead of providing individual speakers 14 for each user in fitness gym 80, a common speaker may be provided in the training space.

[0019] The operation unit 15 is a component for the user to perform various operations and is implemented as a GUI on the display screen 13, which is a touch panel. However, it may also be configured as physical buttons or the like provided on the user terminal 12, rather than being limited to a GUI. As will be described later, the operation unit 15 in this embodiment constitutes an intention expression unit that expresses intentions to the instructor or director based on the user's operations during training.

[0020] The user terminal 12 configured as described above can be a general-purpose electronic device such as a tablet or smartphone. In a fitness gym 80, as will be described later, a dedicated training terminal assigned to each user during training may be pre-installed in the training space, and each function of the user terminal 12 can be realized on that dedicated training terminal. Furthermore, each function of the user terminal 12 may be integrated with training equipment (for example, the bike 103 described below) used by the user on-site or remotely during training.

[0021] The EMS device 102 and the bike 103 are training equipment used by the user during training. The EMS device 102 is an electrical stimulation device worn by the user during training that strengthens muscles by tensing and relaxing them with a weak electric current (EMS stands for Electrical Muscle Stimulation). Specific examples will be described later, but the EMS device 102 is equipped with electrodes that come into contact with the body parts to be strengthened (for example, abdominal muscles, flanks, arms, legs, buttocks, palms), and a weak electric current flows from these electrodes. The EMS device 102 may be configured as fitness wear with multiple electrodes arranged to apply electrical stimulation to multiple body parts simultaneously, or separate EMS devices 102 may be worn individually for each body part.

[0022] Bike 103 is a training device with a shape and structure that mimics a bicycle, and it drives a load-bearing wheel using the leg force applied to the pedals. Bike 103 is a training device that supports voluntary movement, where the user consciously moves their body (in this case, pedaling). In contrast, the EMS device 102 supports involuntary movement, where muscles are forcibly moved by a weak electric current. By wearing the EMS device 102 while training with Bike 103 and pedaling while receiving electrical stimulation from it, the user can perform hybrid training that combines voluntary and involuntary movement. As will be explained in detail later, voluntary movement is generally suitable for training slow-twitch muscle fibers, while fast-twitch muscle fibers, which are difficult to train with voluntary movement, can be effectively trained with involuntary movement using the EMS device 102. Therefore, hybrid training as described above can train both slow-twitch and fast-twitch muscle fibers in a balanced way, dramatically increasing the training effect. A specific example of Bike 103 will be explained later.

[0023] The device information acquisition unit 108 acquires various information from the EMS device 102 and the bike 103. From the EMS device 102, for example, information such as the area to which electrical stimulation is being applied, the intensity of the electrical stimulation, and the frequency of the electrical stimulation can be acquired. From the bike 103, for example, information such as rotation speed, speed, distance traveled, output (also called power or work rate), calories burned, and wheel load can be acquired. This device information is shared with the instructor terminal 12d and the director terminal 12e as needed, and is also sent to the program control unit 3, which will be described later, so that the necessary information is embedded in the video data displayed on the display screen 13 and the audio data played back by the speaker 14.

[0024] The instructor terminal 12d is used by instructors who provide training demonstrations to on-site or remote users. While it can be configured similarly to user terminals 12a, 12b, and 12c, it is preferable to omit or simplify functions corresponding to the control unit 15 so that the instructor can concentrate on the demonstration. As described later, if any operation is required for the user during training, the director, rather than the instructor, will primarily perform the operation from the director terminal 12e. The instructor terminal 12d may be a general-purpose electronic device such as a tablet or smartphone, or it may be a dedicated training terminal assigned to instructors at the fitness gym 80. Furthermore, if the instructor uses training equipment such as the bike 103 themselves for demonstrations, the functions of the instructor terminal 12d may be integrated with those training equipment.

[0025] Camera 109 is a means of capturing live video of the fitness gym 80. Multiple cameras 109 are used to capture dynamic video so that users viewing the live video from their remote personal space 81 can feel the excitement of the fitness gym 80 with a sense of presence, and so that remote users can be inspired by the instructors and other users seriously training in the fitness gym 80, thereby increasing their sense of immersion in the training. During training, these videos are switched and displayed on the display screen 13 according to the processing method defined in training program 2 or by the director terminal 12e at any time. When the instructor demonstrates and explains the training content, it is preferable to show more of the instructor's video so that the user can properly understand it.

[0026] Microphone 110 is an audio acquisition means for acquiring live audio from the fitness gym 80. The most important live audio is the instructor's instructions and motivational voices for the users. Therefore, it is preferable to use a lapel microphone or the like that can be worn hands-free by the instructor during training. In addition, microphone 110 may be provided to acquire audio from the entire training space of the fitness gym 80, or microphone 110 may be provided on each user terminal 12a, 12b to acquire the voices of users in the fitness gym 80. Similarly, a microphone may be provided on the user terminal 12c of a remote user to acquire their voice. In this case, voice communication during training becomes possible between the instructor and users in the fitness gym 80 and the user in the remote personal space 81 via the communication function described later.

[0027] The director terminal 12e is used by the director who supervises training from the training space or back office. While it can be configured similarly to user terminals 12a, 12b, and 12c, the director needs to perform various operations such as starting and ending training program 2, troubleshooting during training, and emergency shutdowns. Therefore, the control unit 15 has more comprehensive functions (see the screen examples below for details). Furthermore, when the director supervises training from the back office, a relatively large electronic device such as a personal computer can be used as the director terminal 12e.

[0028] Training Program 2 primarily consists of EMS instruction data 2A, video data 2B, and audio data 2C, and provides users with electrical stimulation (EMS), video, and audio combined based on each of these data points during training. The length of a single Training Program 2 is arbitrary, but can be set to, for example, 30 to 60 minutes. Alternatively, as described later, a single Training Program 2 may be divided into multiple sets, each lasting, for example, 10 to 20 minutes. In this case, an interval of, for example, 5 minutes can be provided between each set to promote refreshment and recovery from fatigue, and to enhance the user's concentration for the next set. Electrical stimulation may be stopped during the interval, but it is preferable to continue playing video and audio suitable for refreshment.

[0029] EMS instruction data 2A instructs the electrical stimulation to be applied by the user's EMS device 102 during the execution of training program 2. Specifically, it can instruct the frequency and intensity (level) of the electrical stimulation at any time during the execution of training program 2. Furthermore, by regularly changing such frequency and intensity, various electrical stimulation patterns can be realized (such as short, tingling electrical stimulation or slow, pinching electrical stimulation). As will be described later, in this embodiment, the intensity of the electrical stimulation is mainly adjusted based on the user's or director's operations, and in the following description, EMS instruction data 2A will mainly instruct the frequency.

[0030] While any frequency can be specified in EMS instruction data 2A, it is preferable to use the following frequencies for different purposes or phases during training. 4Hz~8Hz: During the warm-up phase, such as at the start of a program, the frequency should begin at 4Hz, progress through an intermediate stage of 6Hz, and then increase to 8Hz to ensure a smooth transition to the main training phase. During the cool-down phase, such as at the end of a program, the frequency should be decreased in the order of 8Hz, 6Hz, and then 4Hz. It is also preferable to use this frequency range during the interval phase between sets. 4Hz: In the training phase, this method encourages single muscle contractions to apply instantaneous load. 20Hz: In the training phase, this promotes incomplete tetanus in the muscles, applying sustained load. Thus, while 4Hz and 20Hz frequencies are mainly used in the training phase, by mixing them over time, it becomes possible to perform effective training that combines short contractions and incomplete tetanics within a single training session or set. As will be described later with respect to Figure 6, the setting unit 56 of the EMS device 102 stores multiple types of EMS modes in which the energizing frequency, energizing time, energizing pattern, etc., are pre-set, and the EMS instruction data 2A consists of data that specifies the EMS mode for each set of the training program 2.

[0031] Video data 2B is the default video data to be displayed on the display screen 13 during training, during intervals between sets, before the start of training, and after the end of training. As will be described later, during training, the live video of the fitness gym 80 captured by camera 109 is mainly displayed, so there are few opportunities for the default video to be displayed in full screen, but it can be used as appropriate when introducing the fitness gym 80 with video or when explaining the training content with video. In addition, backup video can be stored in video data 2B to be played in case the live video of the fitness gym 80 cannot be displayed due to some trouble. As an alternative use for video data 2B to full screen display, when the live video of the instructor is displayed during training, an effect video that can simultaneously represent the direction, size, speed, load, etc. of the training movement may be displayed in the background. For example, it is possible to display a leftward-pointing arrow shape to represent an arm movement to the left, increase the speed of a series of shapes (such as a pentagon) that sequentially approach from the back of the screen to the front when the speed of bike 103 should be increased, flash a fireworks-like image at the timing when repeatedly thrusting the arms out like in boxing, or display a wave-like shape that slowly changes to represent exerting force when performing heavy strength training. If a screen or similar display for showing the above-mentioned effect images is already set up in the background when filming the instructor with camera 109 in fitness gym 80, then the live video captured by camera 109 can be used as is.

[0032] Audio data 2C is default audio data to be played through speaker 14 during the execution of training program 2. It is preferable to prepare background music (BGM) with an appropriate tempo as audio data 2C to match various phases from before the start of training to after the end of training. During non-training periods, for example, before the start of training, during intervals between sets, and after the end of training, it is preferable to use BGM with a calm tempo. During training, it is preferable to use BGM that stimulates the sympathetic nervous system and induces a physical and mental state suitable for strenuous exercise, for example, BGM with a fast tempo and rich rhythm.

[0033] Background music (BGM) during training plays a crucial role in enhancing training effectiveness. First, the instructor can effectively time each voluntary movement during training by matching it to the tempo, rhythm, and volume of the BGM. For example, in training that involves repeatedly thrusting the arms, like in boxing, or training that involves repeatedly pedaling, like in Bike 103, synchronizing the timing of each movement with the rhythm, beat, and intensity changes of the BGM allows the user to experience the pleasure of training in time with the music, forgetting fatigue and concentrating on the training. Furthermore, by synchronizing the electrical stimulation patterns from EMS instruction data 2A with the BGM, not only the voluntary movements mentioned above but also the involuntary movements caused by electrical stimulation are synchronized with the audio data 2C. As a result, the user can continue effective training while experiencing the pleasure of both types of movements being synchronized with the music. In addition, visually confirming that the movements of the instructor and other users displayed on the display screen 13 are synchronized with the music provides a strong sense of unity and exhilaration as if training together with them.

[0034] As described above, in training program 2, synchronizing electrical stimulation from EMS instruction data 2A, video from video data 2B, audio from audio data 2C, and movement instructions from the instructor with high precision is extremely important for enhancing user immersion and maximizing training effectiveness. When a user in the fitness gym 80 receives the above data on-site, the transmission delay difference can be ignored, and the data synchronization state is maintained. However, when the above data is received in a remote personal space 81 via the network 19, the transmission delay difference cannot be ignored, and the data synchronization state may be disrupted. Therefore, in this embodiment, as will be described later, a synchronization signal for data synchronization is added when transmitting the above data to the remote user.

[0035] Furthermore, the training program 2 described above may be prepared as a single package consisting of EMS instruction data 2A, video data 2B, and audio data 2C, which may include archived training sessions that were previously live-streamed or recordings made for future distribution. These recorded training programs 2 may be distributed with a specified start time, similar to live streaming, or they may be made available for continuous distribution so that users can train at their preferred time. In addition, the video data 2A and audio data 2C may be prepared in a format that can be played on portable electronic devices such as tablets and smartphones, or stationary electronic devices such as televisions, similar to general video and music software, and may be provided stored on recording media such as DVDs or Blu-ray Discs (registered trademarks).

[0036] The program control unit 3 includes a training control server 301 and a video server 302 to perform various adjustments to the running training program 2 via the user terminal 12, the device information acquisition unit 108, and the director terminal 12e. The training control server 301 includes a training control unit 3011, a synchronization signal generation unit 3012, and a training information transmission unit 3013. The video server 302 includes a video control unit 3B, an audio control unit 3C, a synchronization signal generation unit 3021, and a video transmission unit 3022.

[0037] The training control unit 3011 receives a training start instruction from the director terminal 12e and generates control data to apply electrical stimulation based on the EMS instruction data 2A at the specified timing. Normally, the training control unit 3011 takes the EMS instruction data 2A stored in the training program 2 as is and uses it as control data. However, if the director terminal 12e performs an emergency stop or similar operation, the training control unit 3011 stops providing the EMS instruction data 2A to all or some of the specified users and safely stops the application of electrical stimulation to those users.

[0038] The video control unit 3B combines default video data stored in the training program 2 with live video data captured by the camera 109 as appropriate to configure video data to be displayed on the display screen 13. As described in detail above, default video data is mainly displayed when not training, and live video data is mainly displayed when training (however, as described above, live video does not need to be displayed on the user's terminal in the fitness gym 80). The audio control unit 3C superimposes live audio from the fitness gym 80 acquired by the microphone 110 onto default background music stored in the training program 2 to configure audio data to be played on the speaker 14 (however, as described above, live audio does not need to be played on the user's terminal in the fitness gym 80). In case of emergency, audio regarding emergency response can also be played from the director terminal 12e.

[0039] Based on the data adjusted by the program control unit 3, electrical stimulation, video, and audio are provided to the user. Specifically, the EMS device 102 provides electrical stimulation to the user based on the EMS instruction data adjusted by the training control unit 3011, the display screen 13 displays video based on the video data adjusted by the video control unit 3B, and the speaker 14 plays audio based on the audio data adjusted by the audio control unit 3C. In this configuration, the EMS instruction data 2A and the training control unit 3011 constitute an electrical stimulation instruction data provision unit that provides instruction data for electrical stimulation to be applied by the electrical stimulation device (EMS device 102) worn by the user during training, the video data 2B, camera 109, and video control unit 3B constitute a video data provision unit that provides video data that the user sees during training, and the audio data 2C, microphone 110, and audio control unit 3C constitute an audio data provision unit that provides audio data that the user hears during training.

[0040] The training information transmission unit 3013 transmits EMS instruction data, which has passed through the training control unit 3011, to a remote user in the personal space 81 via the network 19. At this time, the synchronization signal generation unit 3012 generates a synchronization signal including time information so that the electrical stimulation instructed by the EMS instruction data is applied to the remote user at the appropriate timing. The video transmission unit 3022 transmits video data, consisting of video data that has passed through the video control unit 3B and audio data that has passed through the audio control unit 3C, to a remote user in the personal space 81 via the network 19. At this time, the synchronization signal generation unit 3021 generates a synchronization signal including time information so that the video data is played back to the remote user at the appropriate timing. As will be described in detail below, by comparing the synchronization signal for the EMS instruction data and the synchronization signal for the video data at the receiving end, the EMS instruction data, video data, and audio data can be synchronized with the remote user. The receiving unit 403 receives various data from the remote user terminal 12c and the device information acquisition unit 108c via the network 19.

[0041] Figure 2 shows examples of synchronization signals generated by the synchronization signal generation units 3012 and 3021, and transmission signals generated by the transmission units 3013 and 3022. As shown on the left side of the figure, the EMS instruction data and video data are each divided into packets of a fixed length. In the illustrated example, the EMS instruction data is shown as two packets, EMS Mode #1 and EMS Mode #2, which specify the EMS mode at each point in time. As mentioned above, the EMS instruction data only specifies a pre-set EMS mode, and the amount of data is extremely small. Also, this EMS instruction data can be transmitted all at once at the start of training (it does not need to be transmitted in real time). The video data is illustrated as temporally consecutive packets V#1, V#2, etc. Since this video data includes live video and live audio from the fitness gym 80, it needs to be transmitted in real time during training.

[0042] Figures (A) and (B) on the right side of the diagram show examples of synchronization signal generation. In Figure 2(A), synchronization signals are generated at the same timing for both EMS instruction data and video data and inserted into the transmission signal. Specifically, a synchronization signal S containing training start time information is inserted before the EMS Mode #1 packet and the V#1 packet, and then a predetermined time later, another synchronization signal S containing the same time information is inserted before the EMS Mode #2 packet and V#N+1. This allows the receiving end to synchronize the EMS instruction data and video data by relying on the synchronization signal S, even if a transmission delay occurs in the video data, which has a large amount of data.

[0043] In Figure 2(B), synchronization signals are generated at arbitrary timings for both EMS instruction data and video data, and inserted into the transmission signal. In the illustrated example, the synchronization signal S containing training start time information is inserted in common to both data, but thereafter, synchronization signals can be inserted at arbitrary timings for each. For EMS modes, it is sufficient to insert only the synchronization signal corresponding to the timing of the mode change. For example, if training is divided into 10-minute sets, with one EMS mode set for each, the time information for the start timing of each set can be inserted as the synchronization signal. Thus, the frequency of insertion of synchronization signals for EMS instruction data can be low. On the other hand, it is preferable to insert synchronization signals at a high frequency for video data that changes moment by moment. For example, at frequencies of 1 second, 3 seconds, 5 seconds, 10 seconds, etc.

[0044] In this configuration, the insertion frequency and timing of synchronization signals for EMS instruction data and video data differ, but since the synchronization signal contains time information, synchronization can be performed without problems on the receiving end. For example, if the training start time is 14:00 and a remote user joins late around 14:05, the system first searches for the synchronization signal of the video data, which is inserted at a high frequency. If the synchronization signal for the video data at 14:05 is found, the system then searches for the synchronization signal of the EMS instruction data prior to 14:05. Since the synchronization signal for the EMS instruction data is infrequent, let's assume that the system searches back to the training start time and finds the synchronization signal at 14:00. At this time, the remote user's EMS device 102 uses the 14:00 synchronization signal as a starting point, reads the data for the electrical stimulation to be applied at 14:05 (5 minutes later), and applies the electrical stimulation to the user. In this way, the electrical stimulation to be applied at 14:05 and the video to be played at 14:05 are synchronized. While this synchronization process may cause a time lag between users and instructors or other users at Fitness Gym 80, it can be limited to a few seconds at most, as it only affects the insertion frequency of the synchronization signal in the video data, so it is not a major problem. Even if there is a delay for instructors or other users, the packets received by the user are synchronized, so the user will not notice the delay. One point to note is that the delay will be apparent in the "call and response" exchange with the instructor, which will be discussed later in Figure 17, but this indicates the level of excitement in the training based on the responses of many users, and a delay of a few seconds will not be a major problem.

[0045] In the above explanation, it is assumed that both the training control server 301 and the video server 302 are installed in the fitness gym 80, but all or part of the functions of each server may be implemented on a cloud server or the like on the network 19.

[0046] The communication unit 5 communicates with the training control server 301, video server 302, and receiving unit 403 of the fitness gym 80 via the network 19 in the personal space 81 where the remote user is located. The communication unit 5 comprises a data synchronization unit 501, a receiving unit 502, and a transmitting unit 503. These functions of the communication unit 5 can be realized by a user terminal 12c, which is composed of general-purpose communication devices such as tablets and smartphones. The receiving unit 502 receives EMS instruction data, video data, and audio data with synchronization signals attached, transmitted from the transmitting units 3013 and 3022. The data synchronization unit 501 synchronizes the EMS instruction data, video data, and audio data based on the received synchronization signals. The transmitting unit 503 transmits various data from the user terminal 12c and the device information acquisition unit 108c to the receiving unit 403.

[0047] The data synchronization unit 501 performs the reverse processing shown in Figure 2 based on the received synchronization signal. That is, regardless of whether the signal is in the form of Figure 2(A) or (B), it identifies the respective synchronization signals S for the EMS instruction data and video data, compares them, and performs synchronization processing to place each packet of EMS instruction data and video data at the appropriate provision timing. In this way, it becomes possible to provide synchronized electrical stimulation (EMS device 102c), video (display screen 13c), and sound (speaker 14c) to a user in a remote personal space 81. As mentioned above with respect to Figure 2, the EMS instruction data consists of data specifying the EMS mode at each point in time, which is communicated via the network 19. The EMS device 102c that receives this data generates specific instruction data such as the frequency and intensity of the electrical stimulation. At this time, the function of the electrical stimulation instruction data provision unit, which provides instruction data for the electrical stimulation to be applied by the electrical stimulation device worn by the user during training, is realized not only in the transmitting EMS instruction data 2A and training control unit 3011, but also in the receiving EMS device 102c.

[0048] The motion control system 100 has been outlined above with reference to Figure 1, and now each component will be explained in detail.

[0049] Figure 3 schematically shows the appearance of a fitness garment, which is an example of an EMS device 102 worn by a user during training. The fitness garment 102 consists of a combination of an upper body garment portion 120 that can be worn on the upper body and a lower body garment portion 122 that can be worn on the lower body. The upper body garment portion 120 is a front-opening, short-sleeved top, and the front is opened and closed by a front zipper 130 located along the midline. The upper body garment portion 120 and the lower body garment portion 122 are garments made of a synthetic fiber fabric that is a wearable fabric and is an electrically insulating fabric, and have high elasticity necessary to fit the body regardless of the wearer's body type. The upper body garment portion 120 and the lower body garment portion 122 are worn directly against the skin without any special innerwear. Multiple electrodes are provided on the back surface of the upper body garment portion 120 and the lower body garment portion 122. The arrangement of each electrode will be described later. A right arm zipper 131 is provided on the outside of the right sleeve, running from the cuff to the shoulder, and a left arm zipper 132 is provided on the outside of the left sleeve, also running from the cuff to the shoulder. Closing the right arm zipper 131 and the left arm zipper 132 allows the sleeves to fit more snugly around the arms. Non-slip rubber material is attached to the inside of the left and right cuffs along the inner circumference to prevent the cuffs from rolling up or bunching up during exercise. A right side zipper 133 is provided on the right side, running from the hem to the armpit, and a left side zipper 134 is provided on the left side, also running from the hem to the armpit. Closing the right side zipper 133 and the left side zipper 134 allows the hem to fit more snugly around the torso. Non-slip rubber material is also attached to the inside of the hem along the inner circumference to prevent the hem from rolling up or bunching up during exercise. A right leg zipper 135 is provided on the outside of the right leg, running from the hem to the right hip, and a left leg zipper 136 is provided on the outside of the left leg, running from the hem to the left hip. By closing the right leg zipper 135 and the left leg zipper 136, the hem can be fitted more tightly to the legs. On the inside of both hems, non-slip rubber material is attached along the inner circumference of the hem to prevent the hems from rolling up or flipping up during exercise.In this way, by providing zippers in various places on the upper body garment portion 120 and the lower body garment portion 122, the entire garment can be fitted evenly to the body through the tightening of the zippers and the elasticity of the fabric, thereby maintaining good contact between the electrodes and the skin. Furthermore, by adjusting the degree to which each zipper is closed (or opened), the degree of fit to the body can be adjusted according to the user's preference and body type.

[0050] An upper body control unit 124 is attached to the front of the right side of the upper body garment portion 120. Similarly, a lower body control unit 126 is attached to the front of the left leg of the lower body garment portion 122. The upper body control unit 124 and the lower body control unit 126 control the voltage applied to each electrode. The upper body control unit 124 and the lower body control unit 126 are attached as separate, independent units for the upper and lower body, exposed to the outside. By separating the control units for the upper and lower body, the upper and lower body can be trained at different exercise intensities (set voltage values), and some users can selectively purchase or use only the upper body or lower body muscle electrical stimulation device. Alternatively, the upper body control unit 124 and the lower body control unit 126 can be linked by pairing via short-range wireless communication when they are started up. In this case, operating either the upper body control unit 124 or the lower body control unit 126 will also activate the other, allowing for simultaneous control of the upper and lower body electrical stimulation devices. The upper body control unit 124 and the lower body control unit 126 can also be controlled by a control application installed on a user terminal 12 by pairing them with an information terminal (such as a tablet or smartphone) via short-range wireless communication at startup. In this case, the upper body control unit 124 and the lower body control unit 126 can be operated separately or together. Furthermore, since the upper body control unit 124 and the lower body control unit 126 are mounted on opposite sides of the midline, they are positioned diagonally across the front of the body. Therefore, even when bending the body forward or lifting the thighs or knees upward, the upper body control unit 124 and the lower body control unit 126 can be prevented from colliding and interfering with each other.

[0051] Figure 4 schematically shows the arrangement and wiring of electrodes in the upper body garment portion of the fitness wear. Figure 4(a) shows the front side of the upper body garment portion 120, and Figure 4(b) shows the back side of the upper body garment portion 120. The upper body garment portion 120 has electrodes arranged on the back surface of the fabric, and at least a portion of the fabric has a multi-layer structure in which the outer fabric and the inner fabric are overlapped, with electrical cables wired between the outer fabric and the inner fabric. The electrical cables are water-resistant and elastic. The arrangement and wiring of electrodes and electrical cables are not actually visible externally, so they are shown with dashed lines for explanation.

[0052] The electrodes on the back of the upper body garment portion 120 are located at multiple points corresponding to the target body parts to be electrically stimulated, such as the user's abdominal muscles, flanks, and arms. Each electrode is positioned separately from the others so that current can be supplied to a predetermined body part between them. Each of the multiple electrodes is electrically connected to the first control unit connection portion 20a by individual electrical cables 36. The first control unit connection portion 20a is located at the position corresponding to the upper body control unit 124 in Figure 3, and when the upper body control unit 124 is attached to the first control unit connection portion 20a, the first control unit connection portion 20a and the upper body control unit 124 are electrically connected. Multiple electrical cables 36 connected to each electrode are elastic and, by being secured in place by being wrapped around cable fastening tapes 49 sewn to the upper body garment portion 120 in front of each electrode, the electrical cables 36 are prevented from detaching from each electrode even when the electrical cables 36 are pulled in accordance with the expansion and contraction of the upper body garment portion 120.

[0053] In the area corresponding to the abdominal muscles, a pair of yin and yang electrodes are provided, with a first electrode section 30a on the right and a second electrode section 30b on the left, straddling the rectus abdominis muscle from left to right. Voltage is applied between these electrodes from the upper body control unit 124 via a first electrical cable 36a and a second electrical cable 36b, respectively, to provide electrical stimulation to the rectus abdominis muscle. A first cable fastening tape 49a is sewn in front of the first electrode section 30a, and the first electrical cable 36a, which connects the first electrode section 30a and the first control unit connection section 20a, is wrapped around the first cable fastening tape 49a to fix its position. A second cable fastening tape 49b is sewn in front of the second electrode section 30b, and the second electrical cable 36b, which is routed from the second electrode section 30b on the left abdominal muscle through the left flank, back, and right flank to the first control unit connection section 20a on the front side, is wrapped around the second cable fastening tape 49b to fix its position.

[0054] In the area corresponding to the right flank, a pair of yin and yang electrodes are provided, with a third electrode section 30c on the front side and a fourth electrode section 30d on the back side, straddling the right oblique abdominal muscle from front to back. Voltage is applied between these electrodes from the upper body control unit 124 via the third electrical cable 36c and the fourth electrical cable 36d, respectively, to provide electrical stimulation to the right oblique abdominal muscle. A third cable fastening tape 49c is sewn in front of the third electrode section 30c, and the third electrical cable 36c, which connects the third electrode section 30c to the first control unit connection section 20a, is wrapped around the third cable fastening tape 49c to fix its position. A fourth cable fastening tape 49d is sewn in front of the fourth electrode section 30d, and the fourth electrical cable 36d, which is routed from the fourth electrode section 30d on the back side through the right flank to the first control unit connection section 20a on the front side, is wrapped around the fourth cable fastening tape 49d to fix its position.

[0055] At the location corresponding to the left flank, a pair of yin and yang electrodes are provided, with a fifth electrode section 30e on the front side and a sixth electrode section 30f on the back side, straddling the left oblique abdominal muscle from front to back. Voltage is applied between these electrodes from the upper body control unit 124 via the fifth electrical cable 36e and the sixth electrical cable 36f, respectively, to provide electrical stimulation to the left oblique abdominal muscle. The fifth electrical cable 36e is connected from the fifth electrode section 30e on the front side of the left flank, through the back, to the fourth electrode section 30d, and is electrically connected to the first control unit connection section 20a via the fourth electrode section 30d. A fifth cable fastening tape 49e is sewn in front of the fifth electrode section 30e, and the fifth electrical cable 36e is wrapped around the fifth cable fastening tape 49e to fix its position. The fifth electrical cable 36e is also wrapped around the fourth cable fastening tape 49d sewn in front of the fourth electrode section 30d to fix its position. A sixth cable fastening tape 49f is sewn in front of the sixth electrode section 30f, and the sixth electrical cable 36f, which is routed from the sixth electrode section 30f on the left flank of the back side, through the back and right flank to the first control unit connection section 20a on the front side, is wrapped around the sixth cable fastening tape 49f to fix its position.

[0056] In the area corresponding to the right arm, a pair of yin and yang electrodes are provided, with the 7th electrode section 30g on the upper side (front) and the 8th electrode section 30h on the lower side (back), to sandwich the right biceps and triceps brachii muscles from above and below. Voltage is applied between these electrodes from the upper body control unit 124 via the 7th electrical cable 36g and the 8th electrical cable 36h, respectively, to provide electrical stimulation to the right biceps and triceps brachii muscles. The 7th electrode section 30g and the 8th electrode section 30h sandwich the biceps and triceps brachii muscles from above and below, but the electrode size is not made unnecessarily large. The 7th electrode section 30g is positioned in an anterior direction (towards the elbow) of the most prominent part of the biceps brachii muscle, and the 8th electrode section 30h is positioned in a posterior direction (towards the shoulder) of the most prominent part of the triceps brachii muscle. This allows the biceps and triceps to be clamped not only from above and below but also from the front and back, increasing the stability of the placement and preventing both electrodes from simultaneously shifting toward the shoulder from the muscle ridge due to the vibrations of the electrical stimulation. Furthermore, because the biceps and triceps are electrically stimulated diagonally from above and below and from the front and back, each muscle can be efficiently loaded with relatively small area electrodes and low power. In addition, electrical stimulation can be applied to the biceps and triceps with a small number of electrodes and wiring, which helps to prevent interference with arm movement. The seventh cable fastening tape 49g is sewn in front of the seventh electrode section 30g, and the seventh electrical cable 36g, which is wired from the seventh electrode section 30g through the right armpit on the front side to the first control unit connection section 20a, is wrapped around the seventh cable fastening tape 49g to fix its position. An eighth cable fastening tape 49h is sewn in front of the eighth electrode section 30h, and the eighth electrical cable 36h, which is routed from the eighth electrode section 30h through the right underarm on the back side to the first control unit connection section 20a, is wrapped around the eighth cable fastening tape 49h to fix its position.

[0057] In the area corresponding to the left arm, a pair of yin and yang electrodes are provided, with the 9th electrode section 30i on the upper side (front side) and the 10th electrode section 30j on the lower side (back side), sandwiching the left biceps and triceps brachii muscles from above and below. Voltage is applied between these electrodes from the upper body control unit 124 via the 9th electrical cable 36i and the 10th electrical cable 36j, respectively, to provide electrical stimulation to the left biceps and triceps brachii muscles. The 9th electrode section 30i and the 10th electrode section 30j sandwich the biceps and triceps brachii muscles from above and below, but the electrode size is not made unnecessarily large. The 9th electrode section 30i is positioned in a position shifted forward (towards the elbow) from the most prominent part of the biceps brachii muscle, and the 10th electrode section 30j is positioned in a position shifted backward (towards the shoulder) from the most prominent part of the triceps brachii muscle. This allows the biceps and triceps muscles to be clamped not only from above and below but also from the front and back, increasing the stability of the placement and preventing both electrodes from simultaneously shifting toward the shoulder from the muscle ridge due to the vibrations of the electrical stimulation. Furthermore, because the biceps and triceps muscles are electrically stimulated diagonally from above and below and from the front and back, each muscle can be efficiently loaded with relatively small area electrodes and low power. In addition, electrical stimulation can be applied to the biceps and triceps muscles with a small number of electrodes and wiring, which helps to prevent interference with arm movement. A ninth cable fastening tape 49i is sewn in front of the ninth electrode section 30i, and the ninth electrical cable 36i, which is routed from the ninth electrode section 30i through the left armpit on the front side, the left flank, the back, and the right flank to the first control unit connection section 20a on the front side, is wrapped around the ninth cable fastening tape 49i to fix its position. A tenth cable fastening tape 49j is sewn in front of the tenth electrode section 30j, and the tenth electrical cable 36j, which is routed from the tenth electrode section 30j through the left armpit on the back side, through the left flank, back, and right flank to the first control unit connection section 20a on the front side, is wrapped around the tenth cable fastening tape 49j to secure its position.

[0058] Five electrical cables 36, the 10th electrical cable 36j connecting the 10th electrode section 30j and the 1st control unit connection section 20a, the 9th electrical cable 36i connecting the 9th electrode section 30i and the 1st control unit connection section 20a, the 2nd electrical cable 36b connecting the 2nd electrode section 30b and the 1st control unit connection section 20a, the 4th electrical cable 36d connecting the 5th electrode section 30e and the 4th electrode section 30d, and the 6th electrical cable 36f connecting the 6th electrode section 30f and the 1st control unit connection section 20a, are routed from the back to the front, passing through the central part of the back and the right side of the torso. Near the center of the back, a cable fastening tape 59a is placed to bundle these five electrical cables 36, and the five electrical cables 36 are bundled together near the center of the back by the cable fastening tape 59a. The cable fastening tape 59a may also be sewn and fixed to the central part of the back of the upper body garment section 120.

[0059] With the above arrangement and wiring, electrical cables can be routed without being exposed to the outside. Furthermore, since the components other than the upper body control unit 124 are water-resistant, the fitness wear 102 can be washed simply by removing the upper body control unit 124, without having to remove the electrode section 30 or the electrical cable 36. In the figure, the upper body garment section 120 mainly shows an example with electrodes arranged for men, but the arrangement and size of the electrodes may differ for women.

[0060] Figure 5 schematically shows the arrangement and wiring of electrodes in the lower body garment portion of the fitness wear. Figure 5(a) shows the front side of the lower body garment portion 122, and Figure 5(b) shows the back side of the lower body garment portion 122. The lower body garment portion 122 has electrodes arranged on the back surface of the fabric, and at least a portion of the fabric has a multi-layer structure in which the outer fabric and the inner fabric are overlapped, with electrical cables wired between the outer fabric and the inner fabric. The electrical cables are water-resistant and elastic. The arrangement and wiring of electrodes and electrical cables are not actually visible externally, so they are shown with dashed lines for explanation.

[0061] The electrodes on the underside of the lower body garment portion 122 are located at multiple points corresponding to the target body parts to be electrically stimulated, such as the user's legs and buttocks. Each of the multiple electrodes is electrically connected to the second control unit connection portion 20b by an individual electrical cable 36. The second control unit connection portion 20b is located at the position corresponding to the lower body control unit 126 in Figure 3, and when the lower body control unit 126 is attached to the second control unit connection portion 20b, the second control unit connection portion 20b and the lower body control unit 126 are electrically connected. The multiple electrical cables 36 connected to each electrode are elastic and are secured in place by being wrapped around cable fastening tapes 49 sewn onto the lower body garment portion 122 in front of each electrode, thereby preventing the electrical cables 36 from detaching from each electrode even when the electrical cables 36 are pulled in accordance with the stretching and contracting of the lower body garment portion 122.

[0062] In the area corresponding to the right front thigh, a pair of yin and yang electrodes are provided, with the 11th electrode section 30k at the top and the 12th electrode section 30l at the bottom, straddling the right quadriceps femoris muscle vertically. Voltage is applied between these electrodes from the lower body control unit 126 via the 11th electrical cable 36k and the 12th electrical cable 36l, respectively, to provide electrical stimulation to the right quadriceps femoris muscle. The 11th electrical cable 36k is connected from the 11th electrode section 30k on the right front thigh, through the groin, to the 13th electrode section 30m on the left front thigh, and is electrically connected to the 2nd control unit connection section 20b via the 13th electrode section 30m.

A 14th cable fastening tape 49n is sewn in front of the 14th electrode section 30n, and the 14th electrical cable 36n and the 12th electrical cable 36l, which connect the 14th electrode section 30n and the 2nd control unit connection section 20b, are wrapped around the 14th cable fastening tape 49n to fix their position.

[0064] On the back of the right thigh, a pair of yin and yang electrodes, the 15th electrode section 30o and the 16th electrode section 30p, are provided at the top and bottom, respectively, straddling the hamstrings such as the right biceps femoris. Voltage is applied between these electrodes from the lower body control unit 126 via the 15th electrical cable 36o and the 16th electrical cable 36p, respectively, to provide electrical stimulation to the hamstrings such as the right biceps femoris.

[0068] A cable fastening tape 59b is sewn to the fabric near the crotch of the lower body garment part 122 to secure the 11th electrical cable 36k connecting the 11th electrode part 30k and the 13th electrode part 30m, the 12th electrical cable 36l connecting the 12th electrode part 30l and the 14th electrode part 30n, the 15th electrical cable 36o connecting the 15th electrode part 30o and the 17th electrode part 30q, and the 16th electrical cable 36p connecting the 16th electrode part 30p and the 18th electrode part 30r. The four electrical cables 36 are bundled together and secured near the crotch by the cable fastening tape 59b. A cable fastening tape 59c for securing the 19th electrical cable 36s, which connects the 19th electrode section 30s and the 21st electrode section 30u, and the 20th electrical cable 36t, which connects the 20th electrode section 30t and the 22nd electrode section 30v, is sewn onto the fabric near the center of the upper buttocks of the lower body garment section 122, and the two electrical cables 36 are bundled together by the cable fastening tape 59c and secured near the center of the upper buttocks.

[0069] With the above arrangement and wiring, electrical cables can be routed without being exposed to the outside. Furthermore, since the components other than the lower body control unit 126 are water-resistant, the fitness wear 102 can be washed simply by removing the lower body control unit 126, without removing the electrode section 30 or the electrical cable 36. In the figure, the lower body garment section 122 is also shown as an example with electrodes arranged mainly for men, but the arrangement and size of the electrodes may differ for women.

[0070] As explained above with reference to Figures 3 to 5, when training at the fitness gym 80, the fitness wear 102 is usually provided on-site and worn during training, and returned afterward. On the other hand, when training in a personal space 81, the user can prepare the fitness wear 102 before training and take care of it after training, such as washing it, by following the procedure below.

[0071] In preparation before training, turn the fitness wear 102 inside out and wet all electrode parts 30 with water using a spray bottle or similar. Wetting the electrode parts 30 ensures good contact with the skin and a wide contact area, preventing strong localized electrical stimulation. Then, turn the fitness wear 102 right side out and put it on after opening all the zippers. After putting it on, close the zippers, adjusting the degree to which each zipper is open so that the electrode parts 30 are in close contact with the skin. Also, when wearing the upper body garment part 120 and the lower body garment part 122 at the same time, fasten the connecting buttons that link the two garment parts together to prevent misalignment during wear. Finally, attach the upper body control unit 124 to the upper body garment part 120 and the lower body control unit 126 to the lower body garment part 122 to complete the preparation before training.

[0072] Next, to begin training, turn on the power to the upper body control unit 124 and the lower body control unit 126. Then, as will be described later with reference to Figure 13, perform the synchronization settings for both control units and the pairing settings for both control units and the application. Then, as will be described later with reference to Figure 14(B), set the EMS mode, and as will be described later with reference to Figure 15(A), set the EMS level. This will allow you to start training in the desired EMS mode and EMS level.

[0073] After training, remove the upper body control unit 124 from the upper body garment 120, and remove the lower body control unit 126 from the lower body garment 122. Next, unzip all the zippers and take off the fitness wear 102. The removed fitness wear 102 can be washed in a washing machine or similar appliance.

[0074] When washing fitness wear 102 yourself, you may wash it in any way you like, taking the following points into consideration to avoid damaging the function and performance of fitness wear 102. To protect the electrodes on the back of fitness wear 120, it is preferable to wash it without turning it inside out. Close all zippers to avoid excessive stress on the zipper opening and closing parts during washing. To avoid damage to fitness wear 120, be careful not to put too many fitness wear 120s in the washing machine at once. For example, limit it to a maximum of 5 pieces. The washing method is optional, but to avoid excessive stress during washing, it is preferable to put fitness wear 120 in a laundry net and wash it on a delicate cycle or hand wash it. Similarly, it is preferable to use a detergent that will not damage fitness wear 120, for example, a neutral detergent for clothing. Conversely, it is preferable to avoid using chlorine bleach, acidic detergents, fabric softeners, etc. Also, when spinning, wring gently by hand, or for a short time when using a centrifugal spin dryer, to reduce the burden on fitness wear 120. After dehydration, do not leave it wet; it is best to air dry it in the shade, avoiding direct sunlight, and it is advisable to avoid using a tumble dryer or iron. Additionally, when cleaning, be careful not to rub the electrode area vigorously, and do not wipe it with thinner, benzene, alcohol, etc.

[0075] Figure 6 is a block diagram showing the functional configuration of the control unit. The control unit 128 comprises a power supply unit 22, a control unit 28, and a wireless communication unit 58. The power supply unit 22, the control unit 28, and the wireless communication unit 58 are housed in a casing that can be attached to the control unit connection unit 20. The control unit 28 includes a power supply control unit 50, a current detection unit 52, an electrical stimulation control unit 54, and a setting unit 56. The control unit 128 includes an upper body control unit 124 that is attached to the upper body garment part 120, and a lower body control unit 126 that is attached to the lower body garment part 122, both having the same configuration. However, as a variation, the upper body control unit 124 and the lower body control unit 126 may differ in configuration or shape.

[0076] Each block of the control unit 28 can be implemented in hardware terms by elements and mechanical devices, such as integrated circuits, and in software terms by computer programs, etc., but here we are depicting functional blocks that are realized through the coordination of these. Therefore, it will be understood by those skilled in the art who have read this specification that these functional blocks can be implemented in various ways by combinations of hardware and software. The same applies to the other block diagrams that follow.

[0077] The power supply unit 22 is a secondary battery such as a lithium-ion battery, but it may also be a replaceable primary battery. The power supply unit 22 is electrically connected to the wireless communication module, which serves as the wireless communication unit 58, and the control circuit, which serves as the control unit 28, and supplies power to each of them. A power button may be provided on the control unit 128, and the power supply unit 22 may be turned on or off in response to the operation of that power button.

[0078] The power control unit 50 controls the charging of the power supply unit 22 and transmits information indicating the charging status to the user terminal 12 via the wireless communication unit 58. The current detection unit 52 detects the resistance between the anode and cathode electrodes to determine whether current can be conducted between the electrodes. For example, the current detection unit 52 of the upper body control unit 124 detects the resistance between the first electrode section 30a and the second electrode section 30b corresponding to the abdominal muscles, between the third electrode section 30c and the fourth electrode section 30d corresponding to the right flank, between the fifth electrode section 30e and the sixth electrode section 30f corresponding to the left flank, between the seventh electrode section 30g and the eighth electrode section 30h corresponding to the right arm, and between the ninth electrode section 30i and the tenth electrode section 30j corresponding to the left arm. The current detection unit 52 of the lower body control unit 126 detects the resistance values ​​between the 11th electrode 30k and the 12th electrode 30l corresponding to the right front thigh, between the 13th electrode 30m and the 14th electrode 30n corresponding to the left front thigh, between the 15th electrode 30o and the 16th electrode 30p corresponding to the back of the right thigh, between the 17th electrode 30q and the 18th electrode 30r corresponding to the back of the left thigh, between the 19th electrode 30s and the 20th electrode 30t corresponding to the right buttock, and between the 21st electrode 30u and the 22nd electrode 30v corresponding to the left buttock. The current detection unit 52 detects that current can be supplied if the detected resistance value is below the threshold, and detects that current cannot be supplied if the detected resistance value is above the threshold.

[0079] When the electrical stimulation control unit 54 detects that it is possible to supply power by the current detection unit 52, it applies a set voltage between the anode and cathode electrodes at a predetermined operating time and period as defined in the training program 2, etc. That is, it applies electrical stimulation to the areas where each electrode is located, such as the user's abdominal muscles, flanks, arms, legs, buttocks, etc. The setting unit 56 sets the voltage value and its increase or decrease, which are controlled by the electrical stimulation control unit 54 according to a predetermined training program or EMS mode. The set voltage value can be set to any of 20 intensity levels, for example. In addition to the training program 2 provided from a central server, etc., the setting unit 56 also has built-in training programs and EMS modes that can be executed independently, and the execution of these training programs and EMS modes can also be started by operating a remote control unit connected via wireless communication (for example, an information terminal such as a mobile phone and a control application installed on that terminal).

[0080] The wireless communication unit 58 receives information such as the set voltage from the user terminal 12 via short-range wireless communication and sends it to the setting unit 56. When the setting unit 56 receives information from the wireless communication unit 58 regarding the set voltage value, or information instructing an increase or decrease in the set voltage value, it increases or decreases the applied set voltage value based on the received information. For example, during the voltage value setting process before the start of exercise, each time the set voltage value is increased or decreased, the electrical stimulation control unit 54 applies voltage between the electrodes at the new set voltage value, allowing the user to feel and confirm the new set voltage value, i.e., the exercise intensity. During exercise, i.e., while voltage is being applied, if the wireless communication unit 58 receives instructions from the user terminal 12 to increase or decrease the exercise intensity, it sends information on the increased or decreased set voltage to the setting unit 56, and the setting unit 56 increases or decreases the set voltage value. However, it ignores instructions to increase or decrease exercise intensity received from sources other than the connected user terminal 12 and does not follow instructions to increase or decrease exercise intensity from other devices. This is to prevent unauthorized increases or decreases in voltage values ​​by anyone other than the user. The wireless communication unit 58 may transmit information indicating the voltage application state by the electrical stimulation control unit 54, i.e., the exercise execution state, to the user terminal 12. The control unit 128 may also be provided with a pairing button, and the wireless communication unit 58 may establish a wireless communication connection when the pairing button is turned on. As a modification, the wireless communication unit 58 may connect to a wireless communication unit 58 included in another control unit by pairing via short-range wireless communication. That is, the wireless communication unit 58 of the upper body control unit 124 and the wireless communication unit 58 of the lower body control unit 126 may be wirelessly connected, and one may transmit information such as a set voltage value to the other to link them together. In this case, for example, if a voltage value is set in the setting unit 56 of the upper body control unit 124, the set voltage value is transmitted from the wireless communication unit 58 of the upper body control unit 124 to the wireless communication unit 58 of the lower body control unit 126.

[0081] The EMS device 102 has been described above with reference to Figures 3-6. Next, the bike 103, which is used for training simultaneously with the EMS device 102, will be described.

[0082] Figure 7 shows one example of the configuration of the motorcycle 103. The motorcycle 103A shown in this figure comprises a saddle 1031 on which the user sits, handlebars 1032 on which the user grips, pedals 1033 on which the user pedals with their feet, wheels 1034 that are rotated in accordance with the pedals 1033, a light-emitting part 1035 which is substantially circular in shape and has a larger diameter than the wheels 1034 and is positioned such that the wheels 1034 are substantially inscribed within it, and a frame 1036 which surrounds the light-emitting part 1035 and connects and supports the above components.

[0083] Users training with the bike 103A sit on the saddle 1031, grip the handlebars 1032, and pedal 1033 while wearing the EMS device 102. The load on the pedals 1033 can be adjusted using the load adjustment lever 1037, allowing users to set their desired load for training. The load adjustment lever 1037 has eight load settings depending on its position, with lower loads closer to the saddle 1031 and higher loads closer to the handlebars 1032. The bike 103A is configured to communicate with the user terminal 12 via wired or wireless connection, and load adjustment may be performed via application software installed on the user terminal 12. In addition, the rotation of the pedals 1033 during training is constantly measured by a sensor (not shown), and this data is used by the bike 103A itself or the user terminal 12, which can communicate with the bike 103A, to calculate various data indicating training performance (revolutions per minute, speed, distance traveled, output, calories burned). These performance data, along with load stage data, are collected by the equipment information acquisition unit 108.

[0084] To ensure that the rotation of the pedal 1033, measured by the sensor, accurately represents the user's energy output, it is preferable to use a wheel 1034 with a so-called freewheel structure. In a freewheel wheel 1034, when the user stops pedaling the pedal 1033, the wheel 1034 continues to rotate by inertia, but the rotation of the pedal 1033 stops immediately. For comparison, in a wheel with a so-called direct load-driven structure, even when the user stops pedaling the pedal 1033, not only the wheel 1034 but also the pedal 1033 itself continues to rotate by inertia. Thus, by adopting a freewheel structure, the rotation of the pedal 1033 accurately represents the user's energy output, enabling accurate data sharing between instructors and users in different locations. As will be described later, user rankings are created based on this data, thus ensuring their fairness.

[0085] The light-emitting section 1035 is composed of numerous light-emitting elements such as LEDs arranged continuously along its approximate circumference, and emits light in an approximately circular shape in different ways depending on the rotation state of the pedal 1033. For example, the light can be made to emit more light as the rotation speed of the pedal 1033 increases, the color of the light can be changed according to the rotation speed, or the light emission pattern can be changed according to the rotation speed (e.g., changing the flashing speed, changing the speed at which the light-emitting part appears to move along the approximate circumference).

[0086] Bikes 103A equipped with such light-emitting units 1035 are particularly suitable for installation in a fitness gym 80. Figure 8 shows multiple users training on bikes 103A in a fitness gym 80. An instructor providing training guidance is also riding a bike 103A on a stage in front of the users. Multiple bikes 103A are neatly arranged in the training area in front of the stage, and each user trains on their assigned bike 103A. The lighting is set to a dim level as part of the training effect, making it easy to see how the light-emitting units 1035 on each user's bike 103A illuminate in different ways depending on the rotation speed. The instructor can immediately grasp the status of each user from the illumination state and provide necessary guidance or encouragement in a timely manner. In addition, users participating in training from a remote personal space 81 can view the video of the fitness gym 80 captured by camera 109 on the display screen 13. In this case, just as with the instructor, the remote user can visually grasp the rotation speed of other users in the fitness gym 80 from the illumination status of the light-emitting unit 1035 of each bike 103A, and from this, they can be stimulated and continue training with high motivation and a sense of competition.

[0087] Figure 9 shows another configuration example of the bike 103. The bike 103B shown in this figure has a different design from the bike 103A shown in Figure 7, but it has basically the same configuration and function, so its explanation is omitted. However, the light-emitting unit 1035 that was provided on the bike 103A is not provided on the bike 103B. As described above, it is preferable to install the bike 103A with the light-emitting unit 1035 in a fitness gym 80, but for personal spaces 81 such as homes, it is possible to appropriately choose between the bike 103A, which has a superior design, and the less expensive bike 103B.

[0088] The bike 103 has been described above with reference to Figures 7-9. As mentioned above, in this embodiment, by receiving electrical stimulation from the EMS device 102 worn by the user while training with the bike 103, etc., it is possible to perform hybrid training that combines involuntary movements from the former and voluntary movements from the latter. Figures 10 and 11 show the excellent effects of such hybrid training.

[0089] Figure 10 shows the changes in blood lactate levels before and after exercise for voluntary exercise (Vol), involuntary exercise induced by electrical stimulation (EMS), and hybrid training (Vol + EMS) in the left-hand graph, and the changes in blood lactate levels before and after exercise in the right-hand graph. The unit of physical activity intensity in the left-hand graph, METs, is set to 1 for resting, and the intensity of physical activity is shown as a multiplier from that; for example, normal walking is about 3 METs. Involuntary exercise has a low physical activity intensity (slightly over 1.0 METs) because the body is not moved voluntarily. In this experiment, low-intensity strength training was used as voluntary exercise (about 3.0 METs). In hybrid training, electrical stimulation was applied while performing the same strength training as voluntary exercise. Although the physical activity intensity increased slightly (about 3.7 METs), it remained a low-intensity exercise (for comparison, slow jogging is about 6 METs). Furthermore, the frequency of electrical stimulation applied during involuntary movements and hybrid training was primarily 20Hz, which is suitable for muscle training. Looking at the blood lactate level graph on the right, an increase in blood lactate levels is observed after exercise in all types of exercise, but the increase is particularly pronounced with hybrid training. In particular, when comparing voluntary movements and hybrid training, despite only a slight difference in physical activity intensity in the graph on the left, there is a significant difference in the increase in blood lactate levels in the graph on the right. Thus, it can be seen that hybrid training, which combines voluntary and involuntary movements, has a superior training effect compared to voluntary movements alone.

[0090] Figure 11 shows the changes in oxygen consumption and blood lactate levels as exercise intensity is varied for voluntary exercise only (VOL) and hybrid training (VOL + EMS). In this experiment, aerobic exercise using a Bike 103 was used as the voluntary exercise. In both the oxygen consumption and blood lactate level graphs, hybrid training outperforms voluntary exercise regardless of exercise intensity. Therefore, this experiment also shows that hybrid training has a superior training effect compared to voluntary exercise (alone).

[0091] Hybrid training is thought to be effective because it simultaneously and effectively trains both slow-twitch and fast-twitch muscle fibers. Slow-twitch fibers can be relatively easily trained through aerobic exercise such as walking or cycling, or through light voluntary exercise such as low-intensity strength training. However, training fast-twitch fibers through voluntary exercise requires anaerobic exercise such as sprinting or high-intensity strength training. Thus, for the average user, training fast-twitch fibers is difficult, and they tend to focus only on training slow-twitch fibers. On the other hand, electrical stimulation from the EMS device 102 can easily train fast-twitch fibers, which are difficult to train with low-intensity voluntary exercise. For example, using a frequency of 20Hz for electrical stimulation can induce incomplete tetanus in fast-twitch fibers, providing a sustained load. Based on this understanding, in this embodiment, users are encouraged to wear the EMS device 102 during aerobic exercise using the bike 103, thereby achieving effective hybrid training. Furthermore, the benefits of hybrid training can be obtained by encouraging the use of the EMS device 102 during training that does not involve the bike 103, such as strength training, stretching, yoga, and other light voluntary exercises guided by an instructor.

[0092] The above describes in detail the configuration of the exercise control system 100, particularly the configuration of the EMS device 102 and the bike 103, which are training equipment used by the user during training. The excellent effects of hybrid training that the user can perform based on these configurations have also been explained. Next, the specific processing when executing training program 2 with the exercise control system 100 will be explained with example screens of user terminals 12a, 12b, and 12c (hereinafter sometimes collectively referred to as user terminals 12), instructor terminal 12d, and director terminal 12e.

[0093] Figure 12 shows examples of training explanation screens displayed to the user, instructor, and director before the start of training. Figure 12(A) is the training explanation screen displayed on the user terminal 12, Figure 12(B) is the training explanation screen displayed on the instructor terminal 12d, and Figure 12(C) is the training explanation screen displayed on the director terminal 12e. Since the screen content is almost identical, we will explain the user screen in Figure 12(A) in detail, and only mention the differences between the instructor screen in Figure 12(B) and the director screen in Figure 12(C).

[0094] Figure 12(A) displays the training start time (START: 19:00), training type (bike | race), training name (100 km bike race challenge vol.02), instructor icon and name, training details, EMS mode, and a start button, from top to bottom. The training start time is displayed for live training streams and archived streams with a specified start time. It is not displayed for VOD streams that users can watch at their convenience. The training type indicates whether the training uses Bike 103, or other types such as strength training, stretching, or yoga. The EMS mode displays the electrical stimulation mode for each set of training. The illustrated training is divided into three sets. In Set 1, the user can choose between TRAD mode, which mainly uses a 20 Hz frequency, and SPOT mode, which appropriately mixes 20 Hz and 4 Hz frequencies. In Sets 2 and 3, TRAD mode, which mainly uses a 20 Hz frequency, is pre-specified. After reviewing the above information, the user can press the "Start Preparation" button on the screen to proceed to the next screen.

[0095] A logout button is provided in the upper right corner of the instructor screen in Figure 12(B). This is because multiple instructors and directors may share the same terminal, allowing them to switch terminal users as needed. Furthermore, the training details information is the same as on the user screen in Figure 12(A), but if you wish to modify this information, you can do so by editing the separately registered master information.

[0096] In the director screen shown in Figure 12(C), the distribution settings information is displayed instead of the training details shown in Figures 12(A) and (B). "Yes" and "No" are displayed depending on whether live streaming is available, and whether VOD recording for later distribution is available. This distribution settings information is entered by the program creation staff, instructors, directors, etc., when training program 2 is created, and can be changed as needed before the start of training. When the director presses the "Start Preparation" button at the bottom of the screen to begin training, the system starts accepting users into the fitness gym 80 and personal space 81.

[0097] Figures 13 to 15 show the screens that the user terminal 12 transitions to after the "Start Preparation" button is pressed on the user screen in Figure 12(A). These screens are used to configure the EMS device 102 that the user will wear in order to start training.

[0098] Figure 13(A) shows the screen for configuring the synchronization settings between the upper body control unit 124, labeled as the Top Controller, and the lower body control unit 126, labeled as the Bottom Controller. As instructed on the screen, the two units will synchronize by simultaneously pressing and holding the synchronization buttons 1241 and 1261 on each unit.

[0099] Figure 13(B) shows the screen for pairing the upper body control unit 124 and the lower body control unit 126, which were linked in Figure 13(A), with the application software installed on the user terminal 12. When the pairing start button at the bottom of the screen is pressed, pairing is performed via short-range wireless communication such as Bluetooth®. Once pairing is complete, a pairing completion screen like Figure 13(C) is displayed.

[0100] Figure 14(A) is an instruction screen showing how to attach the upper body control unit 124 and the lower body control unit 126 to the upper body garment section 120 and the lower body garment section 122, respectively. The upper body control unit 124 and the lower body control unit 126, collectively referred to as controllers in this figure, are electrically connected by attaching them to the first control unit connection section 20a and the second control unit connection section 20b, respectively, whose positions are indicated on the screen, thereby enabling the application of electrical stimulation through the control of the upper body control unit 124 and the lower body control unit 126.

[0101] Figures 14(B) and (C) show the EMS mode, i.e., the screen displaying the frequency primarily used for electrical stimulation during training. In the example screen in Figure 14(B), the user can select the EMS mode for each training set from several provided options. In the example screen in Figure 14(C), the EMS mode for each training set is pre-specified and that information is displayed.

[0102] Figure 15(A) shows the screen for setting the EMS level, that is, the intensity of electrical stimulation during training. The EMS level can be selected from 20 levels and can be set individually for the upper body garment part 120 and the lower body garment part 122. As will be described later, the EMS level can also be changed from the screen during training.

[0103] Once the EMS device 102 is configured as described above, the user will be taken to the training preparation complete screen shown in Figure 15(B), where a brief overview of the training program to be started and the settings information of the EMS device 102 (EMS level and EMS mode) will be displayed. The battery levels of the upper body control unit 124 attached to the upper body garment 120 and the lower body control unit 126 attached to the lower body garment 122 will also be displayed, prompting the user to be careful not to let the batteries run out during training. After the user has confirmed this information, pressing the training start button at the bottom of the screen will take them to a waiting screen where they will wait until the training start time.

[0104] Figure 16 shows the screens for starting the entire training and each training set on the director terminal 12e. Figure 16(A) is the screen for starting the entire training. When the director presses the "Start Live Streaming / Recording" button in the center of the screen, the training starts, and live streaming and recording also begin. The display on the button in the center of the screen corresponds to the streaming settings information in Figure 12(C), and the example shown corresponds to the case where both live streaming and VOD recording are "enabled". As other examples, if live streaming is "off" and VOD recording is "enabled", "Start Recording" is displayed; if live streaming is "enabled" and VOD recording is "off", "Start Live Streaming" is displayed; and if live streaming is "off" and VOD recording is "off", this screen is skipped and the screen transitions to the next screen, Figure 16(B). Other elements of this figure will be described later.

[0105] Figure 16(B) shows the screen used by the director to start each set during training after the entire training session has been initiated in Figure 16(A). In the center of the screen, corresponding to the button display in Figure 16(A), "Live Streaming" and "VOD Recording" are displayed. Below this, the status of Set 1, the set to be started, is displayed as "SET 1 Training Preparation...", and further below is a "SET 1 Training Start" button to begin that set. When the director presses this button, the set starts, and the provision of EMS instruction data, video data, and audio data based on training program 2 and program control unit 3 to the user begins. Thus, during live streaming, the provision of EMS instruction data, video data, and audio data is initiated based on the director's operation, not the instructor's. On the other hand, in the case of VOD streaming, which is not live streaming, the entire training session or each set can be started at the user's preferred timing, based on the user's terminal operation, not the director's. A list of users participating in the training is displayed on the right side of the screen; details of this will be described later.

[0106] Figures 17 and 18 show examples of training screens displayed to the user, instructor, and director during training. Figure 17 is an example of a screen for bodyweight training using only the EMS device 102 and no bike 103, and Figure 18 is an example of a screen for bike training using both the bike 103 and the EMS device 102. In each figure, (A) is the training screen displayed on the user terminal 12, (B) is the training screen displayed on the instructor terminal 12d, and (C) is the training screen displayed on the director terminal 12e.

[0107] Figure 17(A) shows an example of a user screen during bodyweight training. A live video 831 of an instructor demonstrating the training is displayed in the center of the screen. The instructor's live audio is played from the speaker 14 of the user terminal 12. A response button 832, which constitutes the user's communication section, is provided in the lower right corner of the screen. By pressing this response button 832, the user can communicate their intentions to the instructor or director. For example, by using the response button 832 to respond to a call from the instructor during training, the user can convey their level of engagement and enthusiasm for the training to the instructor in real time. As a variation, it may be possible to enable more complex communication. For example, icons representing emotions such as joy, anger, sadness, etc., icons indicating evaluation of the training, the ability to select predefined messages, and the ability to input messages using text or emojis are all possible.

[0108] On the left side of the screen, information about the EMS device 102 being worn by the user is displayed. From top to bottom, the status display unit 833, the EMS level adjustment target selection unit 834, the EMS level adjustment unit 835, and the pause button 836 are displayed. The status display unit 833 shows the battery level and EMS level (LV. 8) of the upper body control unit 124 (Top), and the battery level and EMS level (LV. 20) of the lower body control unit 126 (Bottom).

[0109] The EMS level adjustment target selection unit 834 selects the target for which the EMS level is to be adjusted. In the illustrated example, "All" is selected, meaning both the upper body control unit 124 and the lower body control unit 126 are selected. By pressing the "Select" button, it is also possible to select only the upper body control unit 124 or only the lower body control unit 126. The EMS level adjustment unit 835 increases or decreases the EMS level of the selected target for adjustment. In the illustrated example where "All" is selected, pressing the "+" button, which is the level increase button, increases the EMS level of both the upper body control unit 124 and the lower body control unit 126 by one level each. In the illustrated example, Top increases from LV. 8 to LV. 9 (Bottom is at its upper limit of LV. 20 and will not increase further). Also, pressing the "-" button, which is the level decrease button, decreases the EMS level of both the upper body control unit 124 and the lower body control unit 126 by one level each. In the example shown, the Top level decreases from LV. 8 to LV. 7, and the Bottom level decreases from LV. 20 to LV. 19. If only the Top level or only the Bottom level is to be adjusted, each EMS level can be adjusted by one step at a time.

[0110] The pause button 836 is a button that pauses the electrical stimulation of the EMS device 102. If a user feels that the electrical stimulation is too strong or senses any abnormality during training, they can press this button to immediately and safely stop the electrical stimulation. Safety is improved by placing this pause button 836 near the "-" button, which is the EMS level reduction button, and far away from the "+" button, which is the EMS level increase button. In other words, even if a user trying to press the pause button 836 makes a mistake due to the effects of the electrical stimulation, the possibility of pressing the distant "+" button is low, and at best, the adjacent "-" button will be pressed. When this happens, pressing the "-" button will lower the level of electrical stimulation, reducing the possibility of a mistake and allowing the pause button 836 to be pressed safely.

[0111] At the top of the screen, there is an exit button 837 for exiting the training, a status display section 838 that shows the current set number (SET 1), elapsed time (04:55) and a time bar to visually indicate it, a live display (LIVE) to indicate that live streaming is in progress, and the total set time (10:00).

[0112] Figure 17(B) shows an example of the instructor screen during bodyweight training. On the right side of the screen, a list of 839 users participating in the training is displayed along with the total number of participants (3,122). The area showing each user's information displays basic information such as an icon, name or ID, gender, age, and location. In this figure, users participating from a fitness gym 80 called STUDIO are displayed as "STUDIO". Similarly, users in a trial lesson are displayed as "Trial Lesson". As a variation, additional information may be displayed, such as information about the EMS device 102 worn by the user (for example, Top and Bottom EMS levels as shown in the status display unit 833 in Figure 17(A)), information about the user's status (for example, whether or not the pause button 836 in Figure 17(A) was pressed), training performance data calculated based on various measurement data from the EMS device 102 and user terminal 12 as described later (for example, physical activity intensity, calories burned, and a unique performance score as described later in Figure 18), and emotional expressions, evaluations, and messages from the user transmitted via the aforementioned expression unit. Based on the information described above, instructors can timely grasp the attributes and status of users and immediately use this information for instruction and communication with each user.

[0113] On the left side of the screen, there is a condition specification section 840 for specifying the conditions for users to be displayed in the user list 839. When there are many users participating in the training, the user list 839 becomes very long and cannot be displayed on one screen, so the instructor's convenience is enhanced by enabling filtering and sorting using various conditions. In the example shown in this figure, various conditions for filtering users are displayed, and when the instructor clicks on the desired condition, only users that match that condition are displayed in the user list 839. As a variation, various conditions for sorting users may also be displayed. For example, sorting by participation order, age, number of training sessions, performance score, etc.

[0114] A response display unit 841 is provided in the area between the condition specification unit 840 and the user list 839. This corresponds to the response button 832 described in Figure 17(A), and when each user presses the response button 832 in response to an instructor's call, the user's icon is displayed on the response display unit 841 in a floating manner. The instructor can visually recognize the level of user engagement and enthusiasm from the number of icons for each user displayed on the response display unit 841 and the speed at which they are displayed. If user engagement is low, the instructor can increase user engagement and maximize the training effect by shifting the focus from mechanical demonstration of training movements to communication such as encouragement and motivation. Note that such a response display unit may also be provided on the user screen in Figure 17(A). This allows users to visually recognize the responses of other users. In particular, when training is in full swing, seeing the numerous responses from other users displayed in the response display area strengthens the sense of unity with other users, allowing you to immerse yourself in the training while sharing a sense of excitement.

[0115] The status display section 842 in the lower left of the screen shows indicators such as whether live streaming is in progress, whether VOD recording is in progress, and the progress of the training (e.g., SET 1 training in progress).

[0116] Figure 17(C) shows an example of the director screen during bodyweight training. In the center of the screen, status information such as "Live Streaming," "VOD Recording," and "SET 1 Training" is displayed, similar to the status display unit 842 in Figure 17(B). On the right side of the screen, a display similar to the user list 839 in Figure 17(B) is shown. An emergency stop button 843 is provided in the lower left corner of the screen. Based on information acquired by the director terminal 12e from the user terminal 12 and the device information acquisition unit 108, if the director recognizes the need to emergency stop the training, pressing this button will forcibly stop the electrical stimulation from the EMS device 102 worn by the user. As explained in Figure 17(A), the user screen has a pause button 836 that the user can use to stop the electrical stimulation themselves, but it is conceivable that the user may not be able to operate this button. In such cases, the director can remotely stop the training, thereby ensuring the safety of the user. Furthermore, this emergency stop button 843 may simultaneously stop all users' EMS devices 102, selectively stop a specific user's device, or allow both options to be selected.

[0117] Figure 18(A) shows an example of a user screen during bike training. Live video 831 of an instructor demonstrating the training is displayed in the center of the screen. The bike information display unit 844 on the left side of the screen displays the aforementioned information about the bike 103 acquired by the equipment information acquisition unit 108. The user list 839 on the right side of the screen differs from Figure 17 only in the following respects. First, a performance score in units of TG (abbreviation for training gauge) is displayed. This is calculated using a unique formula based on the information displayed in the bike information display unit 844, and users can be ranked based on this. The rank is displayed in the upper left of each user area (2456th-2460th place), and users are displayed in ascending order. The user ranked 2458th, displayed in the center, is the user using this user terminal 12, and can easily check their own rank during training. This increases the sense of competition with other users, enabling more effective training. As described above, by default, the user list of 839 is displayed in a ranking format centered on the user. However, the filtering buttons at the bottom allow you to narrow down the displayed users by various conditions such as age, gender, and relationships such as "friends" or "mutually following." In addition to filtering, you may also want to enable sorting by desired conditions. Other display information is basically the same as in Figure 17.

[0118] Figure 18(B) shows an example of the instructor screen during bike training. The user list 839 on the right side of the screen is the same as in Figure 18(A), but the display can be changed more precisely by specifying filtering and sorting conditions in the condition specification section 840 on the left side of the screen. In addition, users who have broken their personal best measured by TG will be marked with "Personal Best Broken," and the instructor will be able to individually encourage or contact those users. The filtering conditions in the condition specification section 840 are almost the same as in Figure 17(B), but a condition regarding users who have broken their personal best has been added. Also, based on the sorting conditions shown, the display can be updated so that users with predetermined ranks (1st, 100th, 500th) based on TG come to the top of the user list 839. Note that the user list 839 can be scrolled up and down by the instructor's screen scroll operation. Other display information is basically the same as in Figure 17.

[0119] Figure 18(C) shows an example of the director screen during bike training. It is basically the same as Figure 17(C), but the user list on the right side of the screen is the same as that in Figure 18(B).

[0120] Figures 19 and 20 show examples of various screens displayed on the display screen 13 of the user terminal 12 after the training is completed. Figure 19(A) displays the training results. As shown in the figure, training result data such as the ranking (position) among all users in this training, calories burned, distance traveled, and training gauge (performance score) are displayed in summary. The training gauge shows both the current and cumulative values. To stimulate the user's desire for improvement and maintain motivation for future training, stages are set according to the cumulative training gauge, and the training gauge required to advance to the next stage is also displayed. Figure 19(B) is the screen displayed when a stage is advanced. When a stage is advanced, a badge corresponding to each stage is awarded as proof. Training results such as those shown in Figure 19(A) (including detailed data not displayed on this summary screen) and the stages achieved and badges shown in Figure 19(B) are saved as logs in each user's account and can be viewed or managed by the user themselves or the instructor who provides guidance.

[0121] Figure 20(A) shows the screen displayed when a user completes a predetermined mission. Missions can be created as needed by the administrator of the exercise control system 100, and a mission is completed when the user fulfills the predetermined conditions, such as "30 days of training completed" as shown in the figure. Mission completion conditions can be set arbitrarily, but for example, they can be related to numerical training results such as "running distance of XXX km or more" or "burning XXX calories or more," or related to the number or frequency of training participation such as "participating in training XXX times or more" or "training X times or more in one month," or related to other users or instructors such as "having XX or more friends" or "having XX or more favorite instructors." In addition, as a reward for completing a mission, points that can be used to purchase services and products provided by the administrator of the exercise control system 100, or badges can be given to the user to increase user engagement.

[0122] Figure 20(B) shows the screen where users evaluate instructors after training. As illustrated, the instructor's "hospitality," "teaching ability," "communication skills," "performance," and "knowledge" are evaluated on a five-point scale. The evaluation results are reflected in the instructor's ranking and profile information, and serve as reference information for users to select an instructor for future training sessions. Instructors can recognize areas for improvement from this evaluation information and strive to improve the quality of their training to raise their ranking, so users can receive high-quality training from their favorite instructors.

[0123] The present invention has been described above based on embodiments. The embodiments are illustrative, and it will be understood by those skilled in the art that various modifications are possible in combinations of their components and processing processes, and that such modifications also fall within the scope of the present invention.

[0124] While the embodiments primarily described a one-to-many training model in which one instructor instructs multiple users, the present invention can also be applied to a one-to-one training model in which one instructor instructs one user. In particular, when the instructor and user are not in the same location, the EMS instruction data, video data, and audio data can be synchronized through the operation of the synchronization signal generation unit 401 and the data synchronization unit 501 described in the embodiments, allowing the user to train as if they were in the same location as the instructor. Furthermore, the invention is not limited to a model in which an instructor instructs a user; it may also be used in a model in which instructors compete with users in the same training. Moreover, if there are multiple pairs of instructors and users performing a specific type of training, such as cycling, at the same time, the training may be conducted in a model in which these pairs compete with each other.

[0125] Furthermore, although the embodiment was described as being used by one user, multiple users may share a single user terminal 12 while training. In particular, if the user terminal 12 is a device equipped with a large display such as a television, multiple users can gather in the personal space 81 where it is installed and train in front of an instructor displayed on the screen, creating an immersive experience as if they were in a fitness gym 80. Conversely, multiple instructors may appear in sequence or simultaneously within a single training program 2 to instruct one or more users.

[0126] Figure 21 shows one mode of training in a fitness gym 80 and a personal space 81 using a modified exercise control system. In the fitness gym 80, an example is shown where user terminal 12a provides a training program to user 82a, and user terminal 12b provides a training program to user 82b. User terminals 12a and 12b are connected via wireless communication to muscle electrical stimulators attached to fitness wear 102a and 102b worn by the users, respectively, and control the muscle electrical stimulators. In addition, user terminals 12a and 12b are connected to mirror displays 105a and 105b, respectively, which also function as display screens 13a and 13b in the embodiment (Figure 1), and control the display content of the mirror displays 105a and 105b to display videos demonstrating exemplary movements. User terminals 12a and 12b are operated by instructors 83a and 83b. Instructors 83a and 83b demonstrate exemplary movements while verbally giving instructions and advice to users 82a and 82b near user terminals 12a and 12b. As explained in Figure 8, etc., if one instructor provides the same training content to multiple users both on-site and remotely simultaneously, it is not necessary to assign an instructor to each user. User terminals 12a and 12b synchronize the application of voltage to the muscle electrical stimulators on the fitness wear 102a and 102b with the video of exemplary movements displayed on the mirror displays 105a and 105b, thereby achieving synchronization of voluntary and involuntary movements in hybrid training. Here, the video of exemplary movements displayed on the mirror displays 105a and 105b may be live or archived demonstration videos of the instructor filmed by camera 109, or it may be a video of a movement model with the shape of a human body created using CG, etc.

[0127] User terminals 12a and 12b may each be standalone, or they may be linked to each other via a network, or they may be connected to an exercise control management server via a network such as the Internet, and each user may be provided with the training program 2 as described above based on instructions received from the exercise control management server. User terminals 12a and 12b can also display individual content on each mirror display 105a and 105b at individual timings in order to provide training programs individually to multiple people, but in the above-described "one instructor" vs. "multiple users" training, it is preferable that user terminals 12a and 12b display the same information on the mirror displays 105a and 105b via the training program 2 and program control unit 3, except for the posture information of each individual user described later.

[0128] Meanwhile, in a personal space 81 such as a home, the user terminal 12c provides a training program to the user 82c who is training in the personal space 81. The user terminal 12c used in the personal space 81 connects to a muscle electrical stimulator attached to the fitness wear 102c via wireless communication and controls the muscle electrical stimulator. The user terminal 12c is an electronic device such as a tablet terminal that also functions as a display.

[0129] Figure 22 shows the configuration of the mirror display 105. The mirror display 105 comprises a mirror 1051, a display control device 1052, a display device 1053, and a posture sensor 1054. The display control device 1052 is a computer that displays images of movement on the mirror display 105 according to a training program executed on the user terminal 12. The posture sensor 1054 emits infrared light toward the user 82 standing in front of the mirror display 105, and detects the depth of the user, which is the object, using an infrared sensor and an image sensor that detect the infrared light reflected from the object, thereby obtaining a distance image. Based on the detection result, the user's posture is estimated, and an image of the user's skeletal model, etc., based on the estimation result is displayed on the display device 1053 of the mirror display 105.

[0130] Mirror 1051 is a full-length mirror large enough to reflect the entire image of user 82 from the front, while minimizing transmission loss when transmitting infrared and radio waves from the back. Display device 1053 has a screen slightly smaller than the area of ​​mirror 1051 and can display a large body model corresponding to user 82's entire body, for example, a vertical screen equivalent to a 70-inch display. When display device 1053 is installed on the back side of mirror 1051, user 82 can view the image on the screen of display device 1053, which is transmitted through mirror 1051, from the front side of mirror 1051. Mirror 1051 and display device 1053 are installed so that at least the top edge of the screen is above user 82's eye level, for example, higher than the average height of user 82. As display device 1053, general video output devices such as liquid crystal displays, organic EL displays, projectors and screens can be used.

[0131] The posture sensor 1054 is composed of an infrared projector that emits infrared light, an infrared sensor that detects infrared light reflected from an object, an image sensor such as a CMOS sensor that captures reflected light from the object and acquires an image, a directional microphone, etc. The posture sensor 1054 measures the distance (depth) of an object by emitting infrared light onto the object and detecting the reflected infrared light with the infrared sensor, and acquires a distance image by capturing the reflected light from the object with the image sensor. As a modified example, a back-illuminated ToF distance image sensor in which the posture sensor 1054 is integrated with the display control device 1052 may be used. The posture sensor 1054 is installed horizontally, for example, at a height of approximately 55 cm from the floor, and detects the posture of the user 82 with a field of view of approximately 70 degrees horizontally and approximately 60 degrees vertically. In addition, the range of the recommended training space to ensure that the user 82 is within the detectable range of the posture sensor 1054 is drawn on the floor. The training space is set up in a circular shape centered approximately 2.5m from the mirror 1051. To ensure that only users 82 within this training space are recognized, detection outside the distance range of approximately 2.5m from the mirror 1051 is excluded, and only users 82 within 2.5m are targeted for detection. For example, if user 82 leaves the designated training space and approaches the mirror 1051, they will be removed from the detection target of the posture sensor 1054 and the screen will black out. Conversely, if another person passes behind user 82 (outside the training space), they will not be detected. Furthermore, to prevent false detections, a partition such as a roll screen is installed behind user 82, and the mirrors 1051 are positioned facing each other along the wall of the room, so that the mirrors 1051 are as far apart as possible. In this way, the detection accuracy of the posture sensor 1054 can be maintained at a high level. Further variations include replacing the attitude sensor 1054 with a mechanical device such as a gyro sensor or potentiometer attached to the user 82, or using general detection techniques used for motion capture, such as magnetic field fluctuations detected by a magnetic sensor.

[0132] In the installation example shown in Figure 22, the posture sensor 1054 is installed horizontally below the display device 1053 on the back side of the mirror 1051, at a height of approximately 55 cm from the floor. The posture detection range 206 of the posture sensor 1054 is, for example, a field of view of 70 degrees horizontally and 60 degrees vertically, and is configured to detect the entire body of a user 82 standing approximately 2.5 m away from the posture sensor 1054. If the posture sensor 1054 were to be installed above the display device 1053, detection would occur at an angle that looks down on the user 82 from above. In this case, the angle of incidence to the mirror 1051 would be large, and posture detection through the glass of the mirror 1051 may be affected by the refraction of the glass. In contrast, if the posture sensor 1054 is installed below the display device 1053, it can be installed horizontally, making it less susceptible to the effects of refraction by the glass of the mirror 1051. Furthermore, by installing the posture sensor 1054 on the back side of the mirror 1051 and below the display device 1053, the posture sensor 1054 can be made less conspicuous and less susceptible to dust accumulation. The posture estimation unit provided in the display control device 1052 will limit the detection target to only the user 82 and exclude the instructor 83 from detection, even if a person other than the user 82, such as an instructor 83 advising the user 82 on movement, enters the detection range. Additionally, marks may be drawn on the floor to restrict the instructor 83's standing position to a predetermined area. As a variation, the floor position may be configured to be vertically adjustable in height. The floor on which the user 82 moves should be made of an elastic or cushioning material to reduce the transmission of vibrations to users in adjacent booths. Conversely, the floor on which the mirror 1051 is installed should be made of a harder material than the floor on which the user 82 moves to reduce the transmission of vibrations from the user 82's movement to the mirror 1051, thereby suppressing the impact on sensor measurements.

[0133] Figure 23 is an example of a screen that uses the posture sensor 1054 to display the user 82's movement status on the mirror display 105 using objects. On the screen of the display device 1053, an action model 212 is displayed in the lower right corner, and the movement of the action model 212 indicates the action that user 82 should perform. Note that the action model 212 may be a live or archived demonstration video of an instructor captured by the camera 109. This figure is an example of a screen corresponding to an action called "EXPANDER," which involves expanding and contracting both arms. The first position state image 220a and the second position state image 220b, which are double circular objects that indicate the positions corresponding to both hands of user 82 detected by the posture sensor 1054, are displayed in yellow. When user 82 spreads both arms, the first position state image 220a and the second position state image 220b move laterally to follow user 82's hands and change to orange. At this time, the motion state image 222, which is a double rhombus object indicating the motion state, also deforms to expand laterally in accordance with the movement of the user 82's arms. When the arms are fully extended, the first position state image 220a and the second position state image 220b return to yellow, and prior to the next action, a rhombus object consisting only of the frame shape separates from the motion state image 222 and deforms to contract laterally, indicating that the next action is to contract.

[0134] When user 82 contracts both arms, the first position state image 220a and the second position state image 220b move towards the center, contracting in accordance with user 82's hands, and change to orange. At this time, the motion state image 222, which indicates the motion state, also deforms to contract in accordance with the movement of user 82's arms. When both arms reach the fully contracted position, the first position state image 220a and the second position state image 220b return to yellow, and in anticipation of the next action, the first position state image 220a and the second position state image 220b move to the target position of both hands, guiding the user to the next action, and the motion state image 222 also moves in accordance with the first position state image 220a and the second position state image 220b. In addition, a diamond-shaped object consisting only of a frame separates from the motion state image 222 and deforms to stretch horizontally, indicating that the next action is to extend both arms.

[0135] Thus, when user 82 should extend both arms, the frame shape separates from the motion state image 222 and expands horizontally, preceding user 82's movement. Similarly, when user 82 should retract both arms, the frame shape separates from the motion state image 222 and contracts horizontally, preceding user 82's movement. The first position state image 220a and the second position state image 220b also move to the target position, preceding user 82's movement. In this way, user 82 is guided to visually and intuitively understand the direction they should move next, and the motion state is visualized in accordance with user 82's actual movements, making it easier for user 82 to visually understand their own movements. For other movements, the same screen indicates user 82's movement target and movement state using the motion model 212, position state image 220, motion state image 222, etc. If the effect video representing the training movement, as explained as an example of video data 2B in Figure 1, is displayed along with the background of the object in Figure 23, user 82 can also recognize the next movement from the effect video.

[0136] In the upper right corner of the screen, a circular gauge indicates the remaining number of repetitions until the specified number of repetitions for a given movement is reached, and the remaining number is also indicated by a number displayed within the circular gauge. Each training item and each menu, such as warm-up, conditioning, and cool-down, are displayed using objects like those shown in this diagram.

[0137] Figure 24 shows examples of the first to fourth screens. The first example screen in Figure (a) is the "SQUAT&FLY" screen, in which the upper body raises the arms with the elbows bent at a 90-degree angle and moves both arms in and out, while the lower body lowers the hips in conjunction with the movement of closing the arms and raises the hips in conjunction with the movement of spreading them. Specifically, the user lowers the hips while closing both arms while applying electrical stimulation at a frequency of 20Hz for 4 seconds, pauses for 2 seconds, and then raises the hips while spreading the arms while applying electrical stimulation at a frequency of 20Hz again for 4 seconds, with a 2-second pause. At this time, the user is particularly conscious of the thighs, pectoralis major, and latissimus dorsi muscles. In addition, the position and color of the position state image 220 and the color and shape of the movement state image 222 change according to the angle of movement range when the arms (shoulders) are opened horizontally. Furthermore, the position and color of the positional state image 220, and the color and shape of the motion state image 222, change depending on the angle between the thighs (from the knees to the waist) and the horizontal plane. After repeating the above movements for 8 sets, there is a 30-second rest period consisting of a 15-second pause and a 15-second period of electrical stimulation at a frequency of 2 Hz.

[0138] The second screen example in Figure (b) is the "SQUAT & LAT-PULLDOWN" screen. In this exercise, the user lowers their arms and hips while receiving electrical stimulation at a frequency of 20 Hz for 4 seconds, pauses for 2 seconds, and then raises their hips while extending their elbows and spreading their arms upwards while receiving electrical stimulation at a frequency of 20 Hz for 4 seconds, followed by a 2-second pause. During this time, the user should be particularly conscious of their thighs, pectoralis major, and latissimus dorsi muscles. The upper body changes in position and color of position state image 220 and in color and shape of motion state image 222 according to the angle of movement of the upper arms during the arm raising and lowering motion. The lower body also changes in position and color of position state image 220 and in color and shape of motion state image 222 according to the angle between the thighs from the knees to the hips and the horizontal plane. After repeating the above actions for 8 sets, there is a 15-second pause followed by a 15-second period of electrical stimulation at a frequency of 2 Hz, for a total of 30 seconds of rest.

[0139] The third screen example in Figure (c) is the "SQUAT & ARM CURL" screen. In this exercise, the user lowers their hips while raising both forearms for 4 seconds while receiving electrical stimulation at a frequency of 20Hz. After a 2-second pause, the user raises their hips while lowering both forearms for another 4 seconds while receiving electrical stimulation at a frequency of 20Hz, followed by a 2-second pause. During this time, the user should focus particularly on their thighs, biceps, and triceps. The position and color of the position state image 220 and the color and shape of the movement state image 222 change according to the angle of movement range of the forearms during the raising and lowering motion of the upper body. The position and color of the position state image 220 and the color and shape of the movement state image 222 change according to the angle between the thighs from the knees to the hips and the horizontal plane. After repeating the above movements for 8 sets, there is a 30-second rest period consisting of a 15-second pause and a 15-second period of electrical stimulation at a frequency of 2Hz.

[0140] The fourth screen example in Figure (d) is the "CHEST PRESS" screen. Here, the user pushes both forearms forward while keeping them horizontal, while receiving an electrical stimulation of 20 Hz for 4 seconds. After a 2-second pause, the user pulls both forearms backward while keeping them horizontal, while receiving another 20 Hz electrical stimulation for 4 seconds, followed by a 2-second pause. During this time, the user should focus particularly on their thighs, latissimus dorsi, and rectus abdominis muscles. The position and color of the position state image 220 and the color and shape of the movement state image 222 change according to the amount of movement of the forearms while keeping them horizontal (for example, the range of movement from the position where the midpoint of the forearm is aligned with the shoulder to the position where the arm is fully extended). After repeating the above movements for 8 sets, there is a 30-second rest period consisting of a 15-second pause and a 15-second period of electrical stimulation of 2 Hz.

[0141] Figure 25 shows examples of screens 5 through 8. The fifth example screen in Figure (a) is the "EXPANDER" screen, also shown in Figure 23. Here, the user applies an electrical stimulation of 20 Hz for 4 seconds, spreading both arms from a closed position to the sides, pausing for 2 seconds, then applying another 20 Hz electrical stimulation for 4 seconds, closing both arms, and pausing for 2 seconds. This constitutes one set, and the user repeats this 5 times. Next, the user spreads and closes both arms diagonally, with the right arm diagonally above and the left arm diagonally below, repeating this 5 times. Finally, the user spreads and closes both arms diagonally, with the left arm diagonally above and the right arm diagonally below, repeating this 5 times. During this time, the user should be particularly conscious of their thighs, latissimus dorsi, and rectus abdominis muscles. In addition, the position and color of the position state image 220 and the color and shape of the movement state image 222 change according to the horizontal movement angle of the arms. Following this, there will be a 15-second pause, followed by a 15-second period of electrical stimulation at a frequency of 2 Hz, for a total of 30 seconds of rest.

[0142] The sixth example screen in Figure (b) is the "LUNGE TWIST" screen. Here, the user twists their waist and lowers their hips while receiving an electrical stimulation of 20Hz for 4 seconds, pauses for 2 seconds, and then raises their hips while returning to the original position while receiving another 20Hz electrical stimulation for 4 seconds, followed by a 2-second pause. This constitutes one set, and after repeating this for 8 sets, the user switches legs between left and right over a 6-second period and twists their waist in the opposite direction, repeating this for 8 sets. During this time, the user should be particularly conscious of their thighs, rectus abdominis, and oblique abdominal muscles. In addition, the position and color of the position state image 220 and the color and shape of the movement state image 222 change according to the angle of movement in which the shoulders are rotated horizontally around the vertical axis of the body's center. After this, there is a 15-second pause period followed by a 15-second period of electrical stimulation of 2Hz, for a total of 30 seconds of rest.

[0143] The seventh example screen in Figure (c) is the "LUNGE SIDE VENT" screen. Here, the user lowers their hips while leaning their upper body to one side while receiving an electrical stimulation of 20Hz for 4 seconds, pauses for 2 seconds, and then raises their hips while returning to the starting position while receiving another electrical stimulation of 20Hz for 4 seconds, followed by a 2-second pause. This constitutes one set, and after repeating this for 8 sets, the user switches legs between left and right over a 6-second period and lowers their hips while leaning their upper body to the opposite side, repeating this for 8 sets. During this time, the user should be particularly conscious of their thighs, rectus abdominis, and oblique abdominal muscles. In addition, the position and color of the position state image 220 and the color and shape of the movement state image 222 change according to the angle of inclination of the line connecting both shoulders relative to the horizontal plane as the movement is tilted to the side. After this, there is a 15-second pause period followed by a 15-second period of electrical stimulation of 2Hz, for a total of 30 seconds of rest.

[0144] The eighth example screen in Figure (d) is the "KICKBACK" screen. In this exercise, the user rotates both forearms from bottom to front, pivoting around the elbow, while applying an electrical stimulation of 20 Hz for 4 seconds. After a 2-second pause, the user lowers both forearms while applying another 20 Hz electrical stimulation for 4 seconds, followed by a 2-second pause. During this time, the user should focus particularly on their thighs, biceps, and triceps. The position and color of the position state image 220, and the color and shape of the movement state image 222, change according to the rotation angle of the forearms in the anterior-posterior direction, pivoting around the elbow. After repeating the above movements for 8 sets, there is a 30-second rest period consisting of a 15-second pause and a 15-second period of electrical stimulation at 2 Hz.

[0145] Figure 26 shows examples of screens 9 to 11. The 9th example in Figure (a) is the "PUNCH" screen. In this example, the user maintains their posture while receiving an electrical stimulation at a frequency of 20 Hz for 5 seconds, then performs a punching motion in a specified direction while receiving an electrical stimulation at a frequency of 4 Hz for 10 seconds, followed by a 3-second pause. At this time, the position and color of the position state image 220 change depending on whether or not the user was able to reach the specified position among several predetermined positions in the air. After repeating the above actions for 5 sets, the exercise program ends after a cool-down period of 20 seconds each of electrical stimulation at a frequency of 2 Hz applied to the upper and lower body for a total of 60 seconds.

[0146] The 10th example screen in Figure (b) is the "KNEE&ELBOW" screen. In this exercise, the posture is fixed while an electrical stimulation of 20 Hz is applied for 5 seconds, and the movement of bringing the elbow and knee closer together is repeated while an electrical stimulation of 4 Hz is applied for 10 seconds, with a 3-second pause in between. At this time, the color of the positional image 220 changes depending on whether the distance between the elbow and knee is within a predetermined value. After repeating the above movement as one set for 5 sets, the exercise program ends after a cool-down period of 2 Hz electrical stimulation applied to the upper body and then the lower body for 20 seconds each, for a total of 60 seconds.

[0147] The 11th example screen in Figure (c) is the "HIGH KNEE" screen. In this exercise, the posture is fixed while an electrical stimulation of 20 Hz is applied for 5 seconds, and a leg-raising dash motion is performed while an electrical stimulation of 4 Hz is applied for 10 seconds, with a 3-second pause. At this time, the color of the positional image 220 changes depending on whether the knee is raised to a predetermined height. After repeating the above motion for 5 sets, the exercise program ends after a cool-down period of 2 Hz electrical stimulation applied to the upper body and then the lower body for 20 seconds each, for a total of 60 seconds.

[0148] As described above, changes in the shape, color, and arrangement of state objects 218, such as position state image 220 and motion state image 222, can visually indicate the motion status and whether the motion is appropriate by showing the number of repetitions, time, position, distance, angle, range, etc. By visually observing the changes in the shapes, users can intuitively grasp the load of the exercise not only physically but also visually.

[0149] In the above example, in the fitness gym 80, the state object 218 generated by the posture sensor 1054 built into the mirror display 105 was displayed on the display device 1053 of the mirror display 105. However, similar training is possible in a personal space 81 without a mirror display 105. That is, the user's posture can be detected using various sensors built into the user terminal 12c or other electronic devices, and the state object 218 generated based on this can be displayed on the display screen 13c of the user terminal 12c or on a large display such as a television in the personal space 81, as shown in the example in Figure 23. This allows the user in the personal space 81 to refer to exemplary movements from the motion model 212 or demonstration videos of the instructor, and to check the direction of the next movement associated with their own posture using the state object 218, thereby enabling effective training.

[0150] Furthermore, while the above example detailed a sensor for detecting the user's posture, various other sensors can be used to collect information about the user during training, which can then be utilized for real-time instruction by instructors, providing advice to users after training, and improving training programs. For example, by using biosensors that measure vital signs such as heart rate, body temperature, blood pressure, and blood glucose levels, the user's physical condition during training can be precisely understood, and instruction can be provided accordingly. In addition, if an abnormality occurs in a particular user's vital signs, the EMS device 102 for that user can be stopped automatically, or manually by a director who receives an alert notification. In the training of this embodiment, the user wears the EMS device 102 on their upper and lower body, so it is preferable to equip the EMS device 102 with such biosensors. In particular, since the EMS device 102 of this embodiment is configured as fitness wear with a large contact area with the skin, each biosensor can be placed in a body part suitable for measuring each type of vital signs, and various types of vital signs can be acquired with high accuracy. Similarly, by installing sensors that detect user movement, such as acceleration sensors and angular acceleration sensors, on various parts of the EMS device 102 in the upper and lower body, the movement of each part of the user can be precisely understood. Based on these sensors, if a fall is detected by the user, the EMS device 102 can be emergency stopped, similar to the case of abnormal biometric data described above. As sensors outside the EMS device 102, image sensors such as those on tablets or smartphones can be used to capture the user's movements during training, which can be utilized for real-time posture detection, fall detection, and generation of advice information via motion analysis algorithms based on the video, as described in the example above. In addition, measurement data such as temperature, humidity, and sunlight during the user's training may also be utilized.

[0151] Furthermore, as shown in Figure 27, in addition to or instead of sensors that collect various information about the user during training, a sensor 111 may be provided to collect various information about the instructor during training. The main purpose of the sensor 111 is to detect the instructor's movements and gestures and to apply mechanical stimuli such as force, vibration, and movement via mechanical stimulators 104a, 104b, and 104c (hereinafter collectively referred to as mechanical stimulators 104) worn by the on-site user in the fitness gym 80 and / or the remote user in the personal space 81.

[0152] The method, type, installation location, and installation configuration of sensor 111 are arbitrary. For example, to detect the action of tapping the instructor's chest, sensor 111 can be composed of a force-sensing device such as a piezoelectric sensor or push button attached to the chest area of ​​the fitness wear worn by the instructor. Furthermore, actions such as the instructor tapping their own chest, the instructor tapping the user's shoulder (through the screen), and other gestures by the instructor can be detected by using an image sensor that can also be used as camera 109 as sensor 111, and applying known image recognition technology to the acquired image. In addition, the instructor's movements and gestures may be detected using an acceleration sensor or inertial sensor attached to the instructor's arm or face as sensor 111. The posture sensor 1054 for detecting the user's posture shown in Figure 22 may be used as the instructor's posture detection sensor 111 to detect gestures and the like from the instructor's posture. In addition to or instead of the sensors 111 described above, the instructor terminal 12d and / or director terminal 12e may be used to instruct the application of mechanical stimulation to all or designated parts of the mechanical stimulation device 104 for all or some users.

[0153] The various information about the instructor measured by the sensor 111 is input to the training control unit 3011 of the training control server 301 along with the EMS instruction data 2A included in the training program 2. Based on the various measurement data input from the sensor 111, the training control unit 3011 generates control data so that mechanical stimulation is applied to all or designated parts of the mechanical stimulator 104 for all or some of the on-site users in the fitness gym 80 and / or remote users in their personal spaces 81.

[0154] In addition to or instead of mechanical stimulation, the training control unit 3011 may generate control data based on various measurement data input from the sensor 111 to apply electrical stimulation to all or designated parts of the EMS devices 102 of all or some of the local users in the fitness gym 80 and / or the remote users in their personal spaces 81. Furthermore, various information about the instructor measured by the sensor 111 may be input to the video control unit 3B and / or audio control unit 3C of the video server 302. For example, if the sensor 111 detects the instructor tapping their chest as described above, the video control unit 3B may perform visual effects on the display screen 13 of the user terminal 12, such as lighting up the instructor's chest or making it appear as if sweat is splashing from the chest, and the audio control unit 3C may perform audio effects, such as emitting the sound of tapping a chest or other sound effects from the speaker 14 of the user terminal 12.

[0155] The type, method, installation location, and installation configuration of the mechanical stimulator 104 worn by the user are arbitrary. For example, in order to give the user's chest a similar sensation when the instructor taps the chest as described above, the mechanical stimulator 104 can be made up of any device capable of providing mechanical stimulation such as physical force, vibration, or movement, such as a piezoelectric element, vibration device, or haptic device, which is attached to the chest area of ​​the EMS device 102, which is a fitness wear worn by the user.

[0156] With the above configuration, the system can provide mechanical stimulation to the user in real time in synchronization with various information such as the movements and gestures of the instructor detected by the sensor 111 (or based on operations on the instructor terminal 12d and / or director terminal 12e) (or provide electrical stimulation, perform visual effects, or perform audio effects). This creates a sense of unity with the instructor, a feeling of exhilaration during training, and a sense of immersion in the training, thereby achieving a high level of training effectiveness.

[0157] Figure 28 schematically shows the configuration of a motor control system in which the modified electrical stimulation training information communication device is implemented. The following explanation omits details of components common to Figure 1.

[0158] The program control unit 3 includes an EMS control unit 3A, a video control unit 3B, and an audio control unit 3C, which perform various adjustments to the running training program 2 via the user terminal 12, the device information acquisition unit 108, and the director terminal 12e. Normally, the EMS control unit 3A outputs the EMS instruction data 2A stored in the training program 2 as is, but if the director terminal 12e performs an operation such as an emergency stop, it stops providing the EMS instruction data 2A to all or some designated users and safely stops the application of electrical stimulation to those users.

[0159] The communication unit 4 includes a synchronization signal generation unit 401, a transmission unit 402, and a reception unit 403 for communicating with a remote user via the network 19. The synchronization signal generation unit 401 generates a synchronization signal for synchronizing EMS instruction data, video data, and audio data that have passed through the program control unit 3. The transmission unit 402 transmits the EMS instruction data, video data, and audio data with the synchronization signal generated by the synchronization signal generation unit 401 added. The reception unit 403 receives various data from a remote user terminal 12c and an equipment information acquisition unit 108c via the network 19.

[0160] Figure 29 shows examples of synchronization signals generated by the synchronization signal generation unit 401 and transmission signals generated by the transmission unit 402. First, the EMS instruction data, video data, and audio data input from the program control unit 3 to the communication unit 4 are each divided into packets of a fixed length. In the illustrated example, the EMS instruction data is divided into three temporally consecutive packets E#1, E#2, and E#3, the video data is divided into three temporally consecutive packets V#1, V#2, and V#3, and the audio data is divided into three temporally consecutive packets A#1, A#2, and A#3. Here, the subscripts "#1", "#2", and "#3" indicate the timing at which each data should be provided to the remote user. That is, the three packets E#1, V#1, and A#1 with the subscript "#1", the three packets E#2, V#2, and A#2 with the subscript "#2", and the three packets E#3, V#3, and A#3 with the subscript "#3" should each be provided to the remote user at the same timing. These timings are denoted as T1, T2, and T3 below. As described above, if synchronization between these data is achieved with high precision, remote users can immerse themselves in training as if they were training at Fitness Gym 80.

[0161] Figure 29(A) shows an example where the transmission unit 402 transmits EMS instruction data, video data, and audio data in parallel, and the synchronization signal generation unit 401 inserts a synchronization signal representing the delivery timing at the beginning of each packet of each data. The same synchronization signal S1 representing the timing is inserted at the beginning of each packet E#1, V#1, and A#1 with a delivery timing of T1, the same synchronization signal S2 representing the timing is inserted at the beginning of each packet E#2, V#2, and A#2 with a delivery timing of T2, and the same synchronization signal S3 representing the timing is inserted at the beginning of each packet E#3, V#3, and A#3 with a delivery timing of T3. Therefore, in this example, the synchronization signal generation unit 401 generates a synchronization signal at a frequency of one packet. Note that the synchronization signals S1 to S3 only need to be such that the timing of the three data can be synchronized on the receiving side, and it is not necessary for the three data to have the same signal. For example, by writing detailed information such as the elapsed time from the program start time to the synchronization signal S1 of the EMS instruction data, while writing only information to be associated with the synchronization signal S1 to the synchronization signal S1' of the video data and audio data, the receiving side can synchronize the synchronization signals S1 and S1' and obtain detailed information about the timing of data provision from the synchronization signal S1.

[0162] Figure 29(B) shows an example where, instead of inserting a synchronization signal after every packet as in Figure 29(A), a synchronization signal is inserted every N packets, where N is an arbitrary integer greater than 1. After inserting the synchronization signal S1 before the packet with delivery timing T1, the system transmits continuously until the packet with delivery timing TN ("#N") without inserting any further synchronization signals, and then inserts the synchronization signal S2 before the packet with delivery timing TN+1 ("#N+1"). Therefore, in this example, the synchronization signal generation unit 401 generates a synchronization signal at a frequency of N packets. According to this example, each data can be synchronized every N packets. Although it depends on the network environment 19, it is rare for significant transmission delay differences to occur between data within a single packet, and in many cases, synchronizing every multiple packets as in this example is sufficient.

[0163] Figure 29(C) shows an example where the transmission unit 402 transmits EMS instruction data, video data, and audio data in series, and the synchronization signal generation unit 401 inserts a synchronization signal at the beginning of a basic packet group consisting of three packets with the same timing among the three data. Specifically, synchronization signal S1 is inserted at the beginning of a basic packet group consisting of three packets E#1, V#1, and A#1 with a provision timing of T1; synchronization signal S2 is inserted at the beginning of a basic packet group consisting of three packets E#2, V#2, and A#2 with a provision timing of T2; and synchronization signal S3 is inserted at the beginning of a basic packet group consisting of three packets E#3, V#3, and A#3 with a provision timing of T3. Therefore, in this example, the synchronization signal generation unit 401 generates a synchronization signal at a frequency of 3 packets (1 basic packet group).

[0164] Figure 29(D) shows an example where a synchronization signal is inserted every N basic packet groups instead of every 1 basic packet group as in Figure 29(C). After inserting synchronization signal S1 before the basic packet group at delivery timing T1, the data is transmitted continuously until the basic packet group at "#N" (delivery timing TN) without inserting any further synchronization signals, and then synchronization signal S2 is inserted before the basic packet group at "#N+1" (delivery timing TN+1). Therefore, in this example, the synchronization signal generation unit 401 generates synchronization signals at a frequency of 3N packets (N basic packet groups). According to this example, as in Figure 29(B), each data can be synchronized every N packets.

[0165] As shown in Figure 29, which illustrates simple parallel and serial transmission examples, the above technical concept is also applicable to more complex transmission methods, such as MIMO transmission using any number of antennas on both the transmitting and receiving sides. Regardless of the transmission method, a synchronization signal for synchronizing different types of data (EMS instruction data, video data, audio data) should be embedded in the transmitted signal, allowing the receiving side to arrange each data item in a predetermined time order based on the synchronization signal.

[0166] The communication unit 5 communicates with the communication unit 4 of the fitness gym 80 via the network 19 in the personal space 81 where the remote user is located. Corresponding to the components of the communication unit 4, the communication unit 5 comprises a data synchronization unit 501, a receiving unit 502, and a transmitting unit 503. These functions of the communication unit 5 can be realized by a user terminal 12c, which is composed of a general-purpose communication device such as a tablet or smartphone. The receiving unit 502 receives EMS instruction data, video data, and audio data with synchronization signals attached, transmitted from the transmitting unit 402. The data synchronization unit 501 synchronizes the EMS instruction data, video data, and audio data based on the received synchronization signals. The transmitting unit 503 transmits various data from the user terminal 12c and the device information acquisition unit 108c to the receiving unit 403.

[0167] The data synchronization unit 501 performs the reverse processing shown in Figure 29 based on the received synchronization signal. That is, regardless of which of the signals shown in Figures 29(A) to (D) is received, it first identifies the synchronization signal S1, etc., and then uses it as a reference to arrange each packet of EMS instruction data, video data, and audio data at the appropriate provision timings T1, T2, and T3. As a result, packets E#1, V#1, and A#1 are synchronized to provision timing T1, packets E#2, V#2, and A#2 are synchronized to provision timing T2, and packets E#3, V#3, and A#3 are synchronized to provision timing T3. In this way, it becomes possible to provide synchronized electrical stimulation (EMS device 102c), video (display screen 13c), and audio (speaker 14c) to a user in a remote personal space 81.

[0168] Furthermore, even if a remote user joins training program 2 midway through, the data synchronization unit 501 allows them to train in sync with other users. That is, if the synchronization signals generated at predetermined frequencies during the execution of training program 2 are sequentially designated as S1, S2, S3, etc., a user who joins midway through at the timing when the nth synchronization signal Sn is transmitted can start the execution of training program 2 from the nth packet E#n, V#n, A#n, which is synchronized based on that synchronization signal Sn. At this time, a delay of up to a few seconds may occur due to the processing of identifying the synchronization signal Sn and the nth packet, but this is not a major problem. Even if there is a delay for the instructor and other users, the packets that the user receives are synchronized, so the user will not notice the delay. One point to note is that the effect of the delay is apparent in the "call and response" exchange with the instructor mentioned above in Figure 17, but this indicates the degree of excitement in the training based on the responses of many users, and a delay of a few seconds is not a major problem.

[0169] The functional configurations of each device described in the embodiments can be realized using hardware resources, software resources, or through the collaboration of hardware and software resources. Hardware resources can include processors, ROMs, RAMs, and other LSIs. Software resources can include operating systems, applications, and other programs. [Industrial applicability]
