The present invention relates to a discriminating apparatus, an information providing system, a discriminating method, and an information providing method.

BACKGROUND ART Conventionally, research has been attempted to discriminate human movements from images and moving images, and the research fields are also diverse. For example, in Patent Document 1, a passive sensor having a detection element and a plurality of lenses, and a motion discrimination model optimized using a neural network are used to detect a cared person, a patient, an elderly person, etc. from a bed. It is described to detect getting out of bed, falling, and leaving.

Japanese Patent No. 4633865

However, it is desirable that the technique for discriminating the movement not only allows the user to discriminate the presence/absence of falling from the bed but also be applicable to other fields. For example, it can be considered to analyze what kind of sports the user is doing and apply the analysis results to the scene. In this case, in order to analyze the user's motion and the like, it is necessary to previously install a camera capable of capturing an image of the user who plays sports, but there is a problem that the place where the camera is installed is limited. For example, in the case of sports such as running in a gymnasium such as basketball, it is necessary to install a large number of cameras so that the entire gymnasium can be photographed. Also, in outdoor sports, it is necessary to be able to image the tennis court for tennis and the entire court for soccer and the like. Further, in the case of a marathon or a relay road race, it is necessary to install a camera so as to capture an image of the traveling course as a whole, or to take an image while running along with the runner. Also, if there is no space for installing the camera, it cannot be installed. Therefore, it is desirable to be able to analyze the user's exercise situation without using a camera.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory diagram of an outline of an information providing system 1 according to the first embodiment of the present invention. As shown in FIG. 1, the information providing system 1 according to the first embodiment of the present invention includes a plurality of activity meters 10 (activity meters 10-1, 10-2), a determination device 20, and information provision. And a device 30.

The activity meter 10 is worn by each user.
For example, the activity meter 10-1 is worn by the user 11-1, the activity meter 10-2 is worn by the user 11-2, and the activity meter 10-3 is worn by the user 11-3. -2,... Is measuring the amount of activity such as pulse data and acceleration data of each user 11-1, 11-2,.

FIG. 2 is a diagram showing an example of a terminal used as an activity meter in the information providing system 1 according to the first embodiment of the present invention.

As shown in FIG. 2, as the activity meter 10-1, 10-2,..., a wearable terminal 12 that can be worn on a part of the body such as a wrist or a mobile terminal 13 such as a smartphone can be used. .. The wearable terminal 12 is always worn on the wrist while the users 11-1, 11-2,... Are playing sports, and the number of steps, speed, pulse, etc. of the users 11-1, 11-2,. You can get information on the amount of activity. Further, the wearable terminal 12 has a GNSS (Global Navigation Satellite System) function such as GPS (Global Positioning System) and can acquire information on the current location of the user. The GNSS function serves as a position measuring unit that measures the position of the user. Further, by linking the wearable terminal 12 and the mobile terminal 13, the activity amount measurement value of each user 11-1, 11-2,... Can be obtained from a mobile communication network such as LTE (Long Term Evolution) or the Internet 15. It can be transmitted to the determination device 20 via The activity meter 10 is not limited to the wearable terminal 12 and the mobile terminal 13, and various types can be used. If the wearable terminal 12 that can be directly connected to the mobile communication network is used, the data of the wearable terminal 12 can be directly transmitted to the determination device 20.

In FIG. 1, the determination device 20 collects information obtained from the activity meter of each user 11-1, 11-2,... In advance and determines the type of sport, the type of sport, and the activity level of sport. A discriminating unit for generating Then, when the information of the activity meters 10-1, 10-2,... Of the users 11-1, 11-2,. ... determines the type of sport, type of sport, and activity level of sport.

Here, the type of sport is a name that identifies a sport competition. Examples of types of sports include tennis, table tennis, badminton, baseball, softball, soccer, futsal, skiing, snowboarding, mountaineering, hiking, freestyle swimming, breaststroke, butterfly, sprinting, mid-distance running, racewalking, Ekiden races, judo, kendo, karate, etc.

The types of sports are groups classified based on common items of sports. Examples of sports types include racket sports, base sports, soccer systems, snow skiing competitions, outdoor sports, swimming, racing, and martial arts. Sports included in the racket sports are tennis, table tennis, badminton, and the like. Sports included in base sports are baseball, softball, and the like. Sports included in soccer are soccer, futsal, and the like. Sports included in the snow gliding competition are skiing, snowboarding, and the like. Sports included in outdoor sports include mountain climbing and hiking. Sports included in swimming include freestyle, breaststroke, and butterfly. Sports included in the race include short-distance running, medium-distance running, walking, and relay relay race. Sports included in martial arts include judo, kendo, karate, etc.

The determination device 20 determines the type of sport when it is difficult to specify the type of sport. For example, it may be difficult to distinguish baseball and softball from the measurement result of the activity meter, and in such a case, the type of sport is determined as "base sport". In some cases, it is difficult for the determination device 20 to determine whether it is soccer or futsal. In such a case, the determination device 20 determines that the type of sport is “soccer”.

The activity level of sports is expressed as the level of exercise. The activity level is information indicating which of a plurality of levels, such as a large level, a medium level, and a small level. For example, if it is not possible to identify any of the sports type or sports type, or if the exercise is different from the one registered in advance as the sports type or sports type, the activity meter The activity level of the exercise is determined from the measurement result of. For example, when a catch ball is played, it may be difficult to determine whether it is baseball or softball. In such a case, it is determined which activity level the activity is. If you are practicing about competition, you may not be able to identify the type of sport or the type of sport because you are not necessarily doing the competition itself. Even in such a case, by determining the activity level, it is possible to grasp how much exercise is being performed.

Further, if the position information is included in the information from the activity meter 10-1, 10-2,..., From the position information, a candidate for the type of sport can be determined. That is, the sports facility at the position can be determined from the position of the user. If the sports facility in which the user is located can be identified, it is possible to determine candidates for the type of sports that the user is engaged in. For example, if the user is at a golf course, the sport that the user is playing is likely to be golf. If the user is in the gym, the sport he is playing is likely to be volleyball, basketball, or badminton.

The determination device 20 determines the type of sports, the type of sports, and the activity level of sports as described above. The information related to the sports of the user can be used as information that is a starting point of other services.

The information providing device 30 in FIG. 1 acquires the determination information of the type of sport, the type of sport, and the activity level of sport from the determination device 20. Then, the information providing apparatus 30 realizes various other services by using the determined sports type, sports type, and sports activity level. For example, the information providing device 30 transmits the incentive information for the user who uses the activity meter, which is the transmission source of the measurement result, to the user terminal or the user based on the determination result obtained from the determination device 20. The data of is output.

That is, if the type of sport the user is playing can be determined, the sport that the user is interested in can be estimated. Therefore, it is possible to provide the user with information on the identified sport.

For example, if the user 11-1 is playing golf, the schedule of golf, etc. is transmitted to the user's portable terminal with respect to the user 11-1. Further, for example, it is conceivable to send information on a golf membership ticket or information on a golf competition.

If the user 11-3 is playing soccer, the user 11-3 is provided with information about the program in which the soccer player appears, the schedule of the game of the team to which the soccer player belongs, and the like. Send to the terminal. Further, for example, it is conceivable to send a soccer ticket to the user or send goods related to soccer to the user who has been identified as playing soccer.

In addition, it may be possible to provide incentives for sports application games. For example, if a user who plays a soccer application game determines that the user plays soccer based on the measurement result of the activity meter, a special item is added to the application game of the user. Give. This improves motivation to exercise. In addition, in general, there are cases where special items can be obtained by charging for a game, but an opportunity arises that items can be obtained by a method different from charging.

Further, for example, when a person who works for a company plays sports, the determination result is accumulated as an exercise history. If this history satisfies a certain standard, the company side has the advantage of being able to reduce the insurance premium that the company has subscribed to. In addition, a part of the margin for which the insurance premium is lowered is returned to the employee (user). For example, if this history satisfies a certain criterion, it is determined that the employee is less likely to get sick because he or she exercises a certain amount, and an incentive is given to the employee (user) (for example, the accumulated points Depending on the point service that can be exchanged for goods or services, certain points may be given).

It should be noted that the sports performed by the person working for the company may be arbitrary, or may be the sports that the company is focusing on.

As described above, in the information providing system 1 according to the first embodiment of the present invention, from the information of the activity meters 10-1, 10-2,... Weared by the users 11-1, 11-2,. , The type of sports, the type of sports, and the activity level of sports performed by each user 11-1, 11-2,. Then, various services can be realized by using the determined sports type, sports type, and sports activity level.

Next, discrimination of sports by the discrimination device 20 in the information providing system 1 according to the first embodiment of the present invention will be described.

As described above, the information providing system 1 according to the first embodiment of the present invention collects the information obtained from the activity meter of each user 11-1, 11-2,... A discriminating unit for discriminating a type, a sports type, and a sports activity level is generated. First, the generation of the determination unit will be described.

FIG. 3 is a functional block diagram based on a process for generating a discrimination unit in the discrimination device 20 in the information providing system 1 according to the first embodiment of the present invention. In FIG. 3, the control unit 101 performs various processes based on a program. The control unit 101 has functions of a learning activity meter information acquisition unit 102 and a discriminator generation unit 103.

The type of information obtained from the activity meter is a plurality of data obtained from the activity meter such as pulse data, acceleration data, position information, or a single piece of data.

The discriminator generation unit 103 has a program for learning the learning data, performs learning based on the learning activity amount information acquired from the learning activity amount information acquisition unit 102, and determines the discrimination unit ( The determination unit 203) in FIG. 5 is generated.

The output unit 106 outputs the learned model. The output format may be a format used by a third party such as binary data or a software module. Alternatively, it may be output as a software module operating on a website.

Any kind of learning may be used for the learning of the discriminator generation unit 103. For example, machine learning, reinforcement learning, and deep learning by a neural network including a plurality of intermediate layers using AI (Artificial Intelligence) technology. Either of them may be used.

4A to 4D are graphs showing changes in the activity amount for learning. For example, it is assumed that the discriminator generation unit 103 acquires a pulse rate, an X-direction acceleration, a Y-direction acceleration, and a Z-direction acceleration as the learning activity amount as illustrated in FIGS. 4A to 4D.
In FIG. 4A, the vertical axis represents pulse rate and the horizontal axis represents time. 4B to 4D, the vertical axis represents acceleration and the horizontal axis represents time.

The discriminator generation unit 103 uses the measurement data and the type of the sport (for example, “tennis”) as a data set using the measurement data of the amount of activity and the type of the sport performed by mounting the activity meter (for example, “tennis”). Learn the conditions that express the relationship with (tennis). A large number of this data set is input to the discriminator generation unit 103.

For example, at the start of learning, the discriminator generation unit 103 does not know the correlation between the feature amount of the measurement data and the type of sports, but performs labeling (processing of assigning the type of sports) on the measurement data. As learning progresses, the features are gradually identified and the correlation is interpreted. As the learning progresses, the discriminator generation unit 103 determines that the feature amount of the imaging data (the degree of change of the pulse with time, the acceleration time in each of the X-axis direction, the Y-axis direction, and the Z-axis direction). It is possible to bring the condition representing the correlation between the degree of change, the pulse rate, the acceleration in each of the X-axis direction, the Y-axis direction, and the Z-axis direction) and the type of sport closer to the optimum solution. In learning using such a label, learning is performed as supervised learning.

Although the discriminator generation unit 103 is configured to learn the condition indicating the relationship between the feature amount in the measurement data and the type of sport, it does not use the feature amount of the measurement data, You may make it learn the condition showing the relationship of. Further, the discriminator generation unit 103 generates, as one image, an image in which the four measurement data as shown in FIGS. 4A to 4D are expressed as a graph (for example, generated as one image every 10 minutes). Alternatively, the condition indicating the relationship between each pixel included in the image data and the type of sport may be learned.

FIG. 5 is a functional block diagram based on a process for determining a user's sport using the determination unit 203 generated in the information providing system 1 according to the first embodiment of the present invention. 5, the control unit 201, the operation unit 204, the communication unit 205, the output unit 206, and the storage unit 207 are the control unit 101, the operation unit 104, the communication unit 105, the output unit 106, and the storage unit 107 in FIG. The same may be used or different ones may be used.

The control unit 201 has the functions of an activity meter information acquisition unit 202 and a determination unit 203. The discriminator 203 is generated in advance by learning from the data from the activity meter 10-1, 10-2,... By the discriminator generator 103 described above.
