  The activity evaluation device 30 described below includes a measurement device 20 and an evaluation processing device 10 as shown in FIG. The evaluation processing apparatus 10 includes a device that operates according to a program. This type of device is selected from a microcomputer (Microcontroller) having a memory integrated with a processor, a CPU (Central Processing Unit) in which the memory is provided separately from the processor, and the like. This device constitutes a processing unit 11 in the evaluation processing apparatus 10. Moreover, the evaluation processing apparatus 10 includes a device that functions as an interface unit in order to receive an output from the measurement apparatus 20 that measures a user's physical activity or mental activity. This device constitutes an input unit 12 that receives the output of the measuring apparatus 20.

  The evaluation processing apparatus 10 can be realized by executing a program described below on a general-purpose personal computer. In addition, since products such as game machines for electronic games, smartphones, and tablet terminals include devices that operate according to a program, this type of product may be used as the evaluation processing apparatus 10.

  When this type of product is used as the evaluation processing apparatus 10, there is a possibility that the time until it can be used after being taken out can be shortened compared with the case where a personal computer is used. In addition, as will be described later, there are cases where the activity of the user can be measured using a sensor built in this type of product. Therefore, if a program that operates on these products is provided, the activity evaluation device 30 can be simplified. Can be built.

  The evaluation processing device 10 includes an output unit 13 that outputs presentation information to the presentation device 40. As the presentation device 40, for example, a display device capable of displaying a moving image is used. The presentation device 40 may be configured to output audio instead of a display device. When the presentation device 40 is a display device, the form of presentation information presented to the presentation device 40 may include a user's avatar. When the user's avatar is displayed on the presentation device 40, the user can objectively know the evaluation regarding himself / herself.

  As described above, the activity evaluation device 30 includes the measurement device 20 and the processing unit 11. The measuring device 20 measures a user's physical activity or mental activity. The processing unit 11 uses the output of the measuring device 20 to generate evaluation information related to the user's physical activity or mental activity, and generates presentation information to be presented to the user based on the evaluation information.

  The evaluation processing apparatus 10 includes an input unit 12 and a processing unit 11. The input unit 12 receives the output of the measuring device 20 that measures the physical activity or mental activity of the user. The processing unit 11 uses the output of the measuring device 20 input to the input unit 12 to generate evaluation information related to the user's physical activity or mental activity. Further, the processing unit 11 generates presentation information to be presented to the user based on the evaluation information.

  Since the evaluation processing device 10 and the activity evaluation device 30 evaluate the physical activity or mental activity of the user and generate presentation information corresponding to the evaluation, the user performs an objective evaluation on the physical activity or mental activity of confidence. I can know.

  In the configuration example described below, a case where the measurement device 20 is provided separately from the evaluation processing device 10 will be described as an example. However, when a product selected from a game machine, a smartphone, a tablet terminal, or the like is used as the evaluation processing device 10, the measurement device 20 may be provided integrally with the evaluation processing device 10.

(Embodiment 1)
In the present embodiment, as shown in FIG. 1, an activity evaluation apparatus 30 that evaluates a gait, which is a kind of physical activity of a user, using the output of the measurement apparatus 20 and presents the result of the evaluation to the user will be described. . The measuring device 20 includes a three-axis acceleration sensor 211 that is worn on the user's body. The triaxial acceleration sensor 211 can measure accelerations in three directions orthogonal to each other. Note that the measurement device 20 may include a gyro sensor in addition to the triaxial acceleration sensor 211.

  In the present embodiment, the triaxial acceleration sensor 211 constituting the measuring device 20 is housed in a case 200 attached to a belt 201 wound around the waist or abdomen of the user M1 as shown in FIG. The case 200 also houses the transmitter 22 in order to notify the evaluation processing apparatus 10 of the output of the triaxial acceleration sensor 211. The transmission unit 22 can adopt a configuration in which the transmission unit 22 is connected to the input unit 12 of the evaluation processing device 10 by wire, but is configured to perform wireless communication with the input unit 12 using radio waves as a transmission medium. It is desirable.

  The measuring device 20 is preferably mounted near the center in the left-right direction on the user's waist or abdomen. However, even if the measuring device 20 is configured to be put in a pocket or a bag, like the pedometer, by analyzing the components included in the output of the three-axis acceleration sensor 211, the vicinity of the center in the left-right direction in the waist or abdomen The same analysis as that when the measuring device 20 is mounted on is possible.

  The processing unit 11 provided in the evaluation processing device 10 analyzes the gait of the user using the output of the triaxial acceleration sensor 211 received by the input unit 12 from the measurement device 20. The processing unit 11 includes an analysis unit 111 that extracts a feature amount from a signal for each axis output from the triaxial acceleration sensor 211. The analysis unit 111 extracts a signal having a frequency of interest for the signal for each axis.

  For example, a signal component that is a frequency range corresponding to the walking speed represents front / back, left / right, and up / down movements of the waist accompanying walking, and reflects the movement of the legs and the movement of the trunk. Moreover, a part of signal component of a frequency higher than this component contains the component reflecting the motion of the joint bent and stretched with walking.

  Furthermore, by combining a plurality of signal components, it is possible to detect components such as the trunk inclination. For example, if a two-axis signal component is combined and plotted on a two-dimensional plane having two axes of the back and forth movement of the waist associated with walking, a figure similar to a Lissajous figure can be obtained. If the feature amount of this figure is extracted, it is possible to determine whether the left and right center-of-gravity movement is balanced or unbalanced during walking.

  The processing unit 11 includes a comparison unit 112 that collates the feature amount extracted by the analysis unit 111 with the feature amount in a known gait. A feature amount in a known gait is stored in advance in the gait storage unit 113. The gait storage unit 113 stores not only gaits but also feature quantities classified by items such as age group, gender, and occupation. When an item is instructed using the operation unit 50, the corresponding item is stored. Is selected. When the evaluation processing device 10 is configured by a product selected from a game machine, a smartphone, a tablet terminal, or the like, the operation device 50 is realized by a touch panel attached to this type of product.

  The gait classification stored in the gait storage unit 113 includes a gait that slowly steps on the ground (in terms of mimetic words, nocturnal), a gait that walks barefoot (in terms of mimetic words, petapeta), and the like. . In addition to these two examples, the gait classification may include a gait described as snatching, flapping, stinging, etc.

  Occupations among items that classify gaits stored in the gait storage unit 113 are classified in order to give names to characteristic gait types such as top model, ninja, samurai, and wrestler. It is included in the item. When the gait feature quantity stored in the gait storage unit 113 is selected using these names, the user's gait feature quantity is compared with the gait feature quantity selected by these names. It becomes possible to do. That is, the comparison unit 112 compares the feature amount related to the user's gait extracted by the analysis unit 111 with the feature amount of the gait selected from the gait storage unit 113.

  By the way, the processing unit 11 includes a determination unit 114, and the determination unit 114 performs a first operation for determining the type of the user's gait, a user's gait, and a gait according to an instruction from the operation device 50. The second operation for evaluating the degree of difference from the gait selected from the content storage unit 113 is selected.

  In the first operation, the determination unit 114 instructs the comparison unit 112 to compare the feature amounts extracted by the analysis unit 111 with the feature amounts of a plurality of types of gaits stored in the gait storage unit 113. . Here, the feature amount extracted by the analysis unit 111 is compared with the feature amount of all gaits stored in the gait storage unit 113 in principle.

  The determination unit 114 extracts a gait having the highest similarity with the gait feature amount extracted by the analysis unit 111 from the gait feature amounts stored in the gait storage unit 113. The similarity is evaluated using the Euclidean distance or the Mahalanobis distance. That is, the determination unit 114 generates evaluation information indicating which of the types of gaits stored in the gait storage unit 113 is the user's gait. The evaluation information output from the determination unit 114 is input to the presentation control unit 115, and the presentation information to be presented to the presentation device 40 is generated. This presentation information is presented to the presentation device 40 through the output unit 13.

  It is desirable that the presentation information is generated so that the user's avatar displayed on the screen of the presentation device 40 simulates the user's gait, instead of simply presenting the name of the type of gait. That is, the presentation control unit 115 generates presentation information for causing the gait determined by the determination unit 114 to be displayed on the screen of the presentation device 40 as a moving image by the user's avatar. Thus, in the first operation, the user can confirm his / her gait through the avatar. In addition, if age and gender are presented regarding the type of gait, if there is a difference between the age or gender corresponding to the user's gait and the actual age or gender, the user will be motivated to practice walking Become.

  On the other hand, in the second operation, the determination unit 114 compares the feature amount extracted by the analysis unit 111 with the feature amount of one type of gait selected from the gait storage unit 113 using the operation device 50. The comparison unit 112 is instructed. The determination unit 114 obtains similarity as evaluation information for the gait feature quantities compared by the comparison unit 112. The presentation control unit 115 generates presentation information to be presented to the presentation device 40 from the evaluation information. The presentation information is generated so that the user's avatar that simulates the user's gait and the dummy avatar that simulates the gait selected from the gait storage unit 113 are presented side by side.

  In the second operation, if the occupation can be designated from the controller 50, the user can select various gaits of profession, and his gait and the gait of the selected occupation. Can be compared. For example, when the gait of the top model and the gait of the user are presented in the presentation device 40 so as to be comparable, the user can practice to imitate the gait of the top model. Here, since the determination unit 114 generates evaluation information that evaluates the similarity of gaits, it is desirable to display the similarity as evaluation information on the screen of the presentation device 40. The user can confirm the degree of similarity with the gait of the occupation selected from the operation device 50, and the user can devise the gait so as to further increase the degree of similarity, thereby providing the user with entertainment. Can be practiced walking.

  The presentation device 40 is preferably a display device such as a television receiver having a relatively large screen so that the presentation device 40 can be seen while walking. The presentation device 40 may be selected from a wristwatch-type display device, a smartphone, a tablet terminal, or the like if the screen is small.

  In the configuration example described above, the determination unit 114 evaluates the degree of similarity between the user's gait and the ideal gait stored in the gait storage unit 113. On the other hand, the determination unit 114 may evaluate the degree of difference in the user's gait with respect to the ideal gait stored in the gait storage unit 113.

  For example, the feature amount of the corresponding gait may be selected from the gait storage unit 113 by inputting the age and sex of the user from the operation device 50. In this configuration, the determination unit 114 generates evaluation information indicating the degree of difference between the feature amount selected from the gait storage unit 113 and the actual feature amount obtained from the user. As the evaluation information representing the degree of difference, the above-described similarity may be used. However, a value used for similarity evaluation is used for evaluation information of the degree of difference. In other words, when the degree of similarity is low, the degree of difference is large. Either the degree of similarity or the degree of difference may be used for the evaluation information.

  By the way, when an ideal gait is set and the ideal gait is different from the user's gait, the determination unit 114 generates evaluation information that serves as an index related to the health level of the user. May be. For example, by generating a graphic similar to the Lissajous figure as described above and paying attention to the feature amount of this graphic, it is possible to determine whether the right and left centroid movement of the user is balanced or unbalanced. . Further, since the three-axis acceleration sensor 211 is used in the measuring device 20, it is possible to estimate not only the center of gravity movement but also the movement time of the left and right feet, the stepping force of the left and right feet, and the stride. Further, regarding these pieces of information, when the transition with the passage of time is obtained, information about the endurance of the user can be obtained.

  When this kind of information is combined, indicators such as the health of the user's gait and the level of physical strength of the user can be obtained. That is, the determination unit 114 obtains an index indicating the gait soundness, the level of physical strength, and the like regarding the user. Below, these indicators are referred to as health levels. Here, it is assumed that the degree of health is expressed by the determination unit 114 as a numerical value and a state using the health of the gait and the level of physical strength.

  When the determination unit 114 obtains the health level, the presentation control unit 115 desirably generates the presentation information so that the avatar to be presented to the presentation device 40 is expressed in a posture corresponding to the health level. FIG. 3 is an example of the posture of the avatar A1 corresponding to the health level. FIG. 3A shows a case where the health level is greater than or equal to a predetermined reference value, and FIG. Shows an example in which the health level is less than a predetermined reference value. Note that the reference value corresponding to FIG. 3A and the reference value corresponding to FIG. 3C may be different. The posture shown in FIG. 3 is an example, and the categories related to the health level are not limited to three.

  In this way, when the health level is expressed by the posture of the avatar A1, an intuitive stimulus can be given to the user, compared to the case where the health level is expressed by a numerical value. That is, the user can easily be aware of the health level. Further, since the health level is presented to the user using the avatar A1 and the user performs health management in a game sense, the user's motivation for health management is improved.

  Here, when the plurality of activity evaluation devices 30 are configured to communicate through an electric communication line such as the Internet or a mobile communication network, the health level of other users is confirmed by the posture of the avatar A1. It becomes possible.

  For example, if each member of the family owns the activity evaluation device 30 and can communicate with each other between the activity evaluation devices 30 owned by the family members, the avatars of other families can be confirmed. It becomes possible to do. Therefore, it is possible for the user not only to check his / her own health level but also to check the health level of a family living together, a family living far away, an elderly family, and the like. If the health level of other users is confirmed in this way, it can lead to consideration of the health level of others and can also be used to watch over the family.

  In addition, a doctor or a health advisor may have a presentation device 40 that receives presentation information output from the evaluation processing device 10 and may be used for health management related to the user of the evaluation processing device 10.

  Since the output of the measuring device 20 includes information on the state of muscular strength and the state of the joint, it is desirable that the determination unit 114 extracts the evaluation information on the health level from these pieces of information. In addition to the output of the three-axis acceleration sensor 211, it is desirable to report information such as the height and weight of the user using the operation device 50. When such information is obtained, the presentation control unit 115 may be configured to generate meal content or a meal recipe suitable for the health condition of the user as the presentation information.

  The presentation information generated by the presentation control unit 115 may be individually held by the evaluation processing device 10, but this kind of information can be shared by a plurality of evaluation processing devices 10. For this reason, it is desirable that the presentation control unit 115 acquires meal contents or meal recipes suitable for the health condition from the web server through an electric communication line such as the Internet. The web server may be composed of a plurality of computers instead of a single computer, and may be a cloud computing system.

  By the way, this embodiment can be used for walking practice or practice of imitating a gait. Therefore, various rewards may be given to practice in order to further improve the entertainment characteristics of such practice.

  Examples of this type of reward include giving points that can be used in a virtual space, expanding a range in which action can be performed in a virtual space, and giving a tool that improves superiority in other games. For example, when the user's avatar is a resident of a virtual space, a point that can be exchanged for a product or service in the virtual space may be given as the health level improves. As an example, if a product or service related to the avatar's dwelling in the virtual space or the avatar's fashion in the virtual space can be exchanged for points, storing points is a motivation to improve health.

  For example, 100 points are given for a certain health level, and a post attached to a residence is set to 2000 points. For fashion, 500 points for a skirt, 500 points for a jacket, 500 points for a hairstyle shortcut, etc. are set.

  The relationship between the points necessary for receiving goods or services in the virtual space and the provision of points according to the degree of health needs to be set appropriately. That is, if the degree of effort to improve the health level is appropriately matched with the level of desire for goods or services, it becomes possible for the user to maintain motivation to improve the health level.

  Also, for users with weak muscle strength or those with poor knee joints, the range in which they can act in the virtual space is narrowed, and the range in which they can act in the virtual space is increased as the health level increases. Also good. In this case, information related to the virtual space that is outside the current action range may be included in the presentation information so as to make the user aware of information about the virtual space that is outside the current action range. desirable.

  For example, if the presentation information includes a signboard of a store that exists outside the current action range in the virtual space, the user is directed to the corresponding store, and as a result, the current action range Motivate to expand the range of action outside. As described above, the action range in the virtual space is expanded with the improvement of the health level, so that the motivation is increased to further increase the health level.

  Points can be determined according to the degree of improvement in health level, but instructions are given to exercise to improve health levels, and given points are given when the specified content is achieved, or instructions are given. Points may be awarded according to the degree of achievement of the contents. For example, when an instruction of running of 3 km or more is given and the user achieves this exercise, 200 points may be given to the user.

  Note that if the user reports the running distance, it is not proved that the user has exercised. Therefore, it is desirable to quantitatively evaluate the content of the exercise using the output of the measuring device 20. Further, even when the instructed exercise has not been achieved, points may be given at a rate according to the degree of achievement.

  The above-described operation associates the health level with the virtual space in which the avatar acts. On the other hand, the presentation control unit 115 can generate the presentation information as shown in the presentation device 40 in the order related to the integrated value of points, and in order to improve the fighting ability in the competitive game. You may be able to exchange points with weapons that use points or improve your combat ability. Here, the fighting ability may be either attack power or defense power. Note that the rules and contents of the game are defined in the game unit 14. Therefore, characters used in the game, character movements, and the like are determined in the game unit 14.

  When the ranking of the accumulated point value is used as the presentation information, the activity evaluation apparatus 30 is configured to communicate with the server through an electric communication line such as the Internet, and the rank regarding the accumulated point value is obtained in the server. In addition, since the accumulated value of points may increase as the time during which the activity evaluation device 30 is used, unless a time limit is set, it is selected from a past predetermined period (for example, 3 months, 6 months, etc.). It is desirable to show the ranking in

  When points are used in association with a competitive game, it is desirable to increase or decrease the battle ability exchanged for points according to the points. For example, when a point is exchanged with a weapon, it is determined that 200 points are exchanged when the weapon is a sword, and 500 points are exchanged when the weapon is a shield. In this case, the shield has a higher combat ability than the sword.

  A game that associates a user's walking motion is not limited to a competitive game. For example, the walking motion may be associated with a game that simulates a board game on the screen of the presentation device 40. The configuration example illustrated in FIG. 4 is configured such that a square LT is displayed on the screen of the presentation device 40 and the user can move forward by one square when the user walks a predetermined number of steps. The direction of the user is also taken into consideration, and if the user changes the direction, the user can proceed to the grid in the corresponding direction.

  The screen of the presentation device 40 also displays the user's avatar A1 (or an appropriate character), and the avatar A1 operates according to the user's gait. That is, if the user walks at a low speed, the avatar A1 also moves at a low speed, and if the user runs, the avatar A1 also runs. In the grid LT, the current position (P1) of the avatar A1 and the goal position (P2) are shown. The game is established by the user walking so as to move from the current position (P1) to the goal position (P2).

  In the configuration of the present embodiment, when the user walks does not necessarily mean that the user moves forward by walking, and stepping at the same position is also included in the walking. Of course, when the presentation device 40 is portable, the user may actually walk outdoors.

  In addition, when a game machine or a smart phone has a built-in triaxial acceleration sensor, a triaxial acceleration sensor built in this type of product may be used for detecting a gait. That is, in this type of product, it is possible to execute a program (so-called application if it is a smartphone) that functions as the evaluation processing device 10 and analyze the output of the three-axis acceleration sensor built in the product. Is possible.

  When a game machine or a smartphone is used as the evaluation processing apparatus 10, a fixture for fixing the game machine or the smartphone is provided on a belt that is wound around the user's waist or stomach. Therefore, by providing such a belt and the above-described program, a game machine or a smartphone can be used as the evaluation processing device 10.

  In the activity evaluation apparatus 30 described above, the measurement apparatus 20 includes a three-axis acceleration sensor 211 that is worn on the user's body. In addition, the processing unit 11 uses the output of the triaxial acceleration sensor 211 to generate evaluation information related to the user's gait. Therefore, the user can know objectively the evaluation regarding his gait.

(Embodiment 2)
In the present embodiment, as illustrated in FIG. 5, the measurement device 20 includes a sleep sensor 212, and the output of the measurement device 20 is given to the evaluation processing device 10. As the sleep sensor 212, for example, a three-axis acceleration sensor is used. In this configuration, the measuring device 20 is placed on the bedding, and the vibration component due to the user's body movement is extracted. The user's sleep state is estimated by analyzing this vibration.

  It is desirable that the measurement device 20 of the present embodiment is configured to be carried by a user. In this configuration, the measuring device 20 can also be used for measuring the amount of activity when the user is active. Therefore, the measurement apparatus 20 of the present embodiment includes a case 200 (see FIG. 2) attached to the belt 201 wound around the waist, as in the first embodiment, or a wristwatch-type case 200 and a pendant-type case 200. Etc. can also be used.

  The vibration component related to the user's body movement output from the sleep sensor 212 includes a period in which the amplitude is relatively large and a period in which the amplitude is relatively small, as shown in FIG. 6A, for example. In general, it is known that body movement decreases when sleep deepens, and body movement increases when sleep becomes shallow. From this, when the vibration component of body motion as shown in FIG. 6A is used, it is estimated that the time change of the sleep depth becomes as shown in FIG. 6B.

  The processing unit 11 of the present embodiment includes an analysis unit 116 that extracts the amplitude of the vibration component output from the measurement device 20 and estimates the sleep depth based on the time elapsed from falling asleep to waking up and the amplitude of the vibration component. . Sleeping means the time when the sleep depth first becomes maximum after going to bed, and waking up means the time when the sleep depth finally becomes minimum.

  The processing unit 11 includes a comparison unit 117 that compares the time change of the user's sleep depth estimated by the analysis unit 116 with the time change of the ideal sleep depth shown in FIG. 6C. The comparison unit 117 has a function of obtaining a correlation coefficient between the time change of the user's sleep depth and the time change of the ideal sleep depth and scoring the correlation coefficient. This score is called “sleep score”. The comparison unit 117 also scores the time from bedtime to falling asleep and the rising characteristics of sleep depth when waking up by comparing the time change of the user's sleep depth with the time change of the ideal sleep depth. .

  These scores are referred to as “sleeping score” and “sleeping score”, respectively. The sleeping score, sleeping score, and waking up score are all 100 points, and the higher the score, the better the quality of sleep. For example, the sleeping score is calculated as 85, the sleeping score is 60, and the sleeping score is 45. These scores are generated as evaluation information.

  The evaluation information generated by the comparison unit 117 is given to the presentation control unit 118 and presented to the presentation device 40 through the output unit 13. In the above-described configuration, the evaluation information is digitized as the number of sleep points, the number of sleeping points, and the number of sleeping points, so the presentation control unit 118 presents these numerical values to the presentation device 40 as presentation information.

  By the way, the evaluation processing apparatus 10 includes a communication unit 15 for transmitting the score obtained by the processing unit 11 to the server. The score obtained by the comparison unit 117 is transmitted to a server (not shown) through an electric communication line such as the Internet or a mobile telephone network. As in the first embodiment, the server is not necessarily configured by a single computer, but may be configured by a plurality of computers, or may be a cloud computing system.

  The server receives the scores from the plurality of evaluation processing devices 10 and arranges the received sleep score, the score of falling asleep, and the score of waking up in descending order from the highest score, and assigns ranks as shown in Table 1. In Table 1, the ranking is given using the scores of all the participants, but the clustering of the participants may be performed to be divided into a plurality of groups, and the ranking may be given within the group. When performing clustering, it is desirable to use not only the score but also other attributes such as age group and gender.

上述したように、解析部１１６は、計測装置２０が出力した振動成分を解析するから、睡眠深度の時間変化を推定するだけではなく、寝返り、いびきなどの情報も抽出することが可能である。解析部１１６が抽出したこれらの情報を評価情報に用いることによって、利用者の睡眠状態を利用者に知らせることが可能になる。この種の情報を評価情報に用いる場合、提示制御部１１８は、睡眠状態を表すアバターＡ１（あるいは、キャラクタ）を生成し、評価情報に応じてアバターＡ１姿勢が変わるように提示情報を生成する。

As described above, since the analysis unit 116 analyzes the vibration component output from the measurement device 20, it can not only estimate the temporal change in the sleep depth but also extract information such as turning over and snoring. By using these pieces of information extracted by the analysis unit 116 as evaluation information, the user's sleep state can be notified to the user. When this type of information is used for the evaluation information, the presentation control unit 118 generates an avatar A1 (or character) representing the sleep state and generates the presentation information so that the avatar A1 posture changes according to the evaluation information.

  For example, FIG. 7A shows a deep sleep state, FIG. 7B shows a snoring state, and FIG. 7C shows a shallow sleep depth and a state of turning over. Since these states change with the passage of time during sleep, the presentation control unit 118 expresses the motion of the avatar A1 as a moving image. That is, the user can know the relationship between the sleeping time and the sleeping state. It is possible to change the reproduction method of this moving image by operating the operation unit 50. The operation device 50 can select, for example, 0.8 × speed playback, 1.3 × speed playback, fast forward, and the like.

  Thus, by representing the sleep state of the user using the avatar A1, the user can recognize the change in the sleep state over time. In particular, the user is aware of the sleep state, knows the possibility of sleep apnea syndrome, and is able to show the snoring state to the family, snoring has become a nuisance to the family Will know.

  In addition, it is known that turning over occurs in a period during which transition from non-REM sleep to REM sleep or a period during which transition from REM sleep to non-REM sleep occurs. Therefore, by extracting the time zone in which the turn is occurring, it can be used for the evaluation of sleep quality.

  By the way, as described above, the sleep sensor 212 of the measurement device 20 used in the present embodiment can also be used for measuring the amount of activity. The analysis unit 116 also has a function of estimating the amount of sleep and the amount of activity based on the output of the measurement device 20. The analysis unit 116 calculates the sleep amount using the sleep time and the sleep depth as parameters. The amount of activity is calculated based on the integrated value of acceleration.

  The comparison unit 117 compares the amount of sleep and the amount of activity with a predetermined reference value set for each. Further, the comparison unit 117 evaluates that the sleep amount and the activity amount are both equal to or greater than the reference value, and that the sleep amount and the activity amount are both less than the reference value, and the activity amount is equal to or greater than the reference value. Even so, if the amount of sleep is less than the reference value, it is evaluated that sleep is insufficient. In addition, since there is a possibility of disturbing sleep if the amount of activity is excessive, it is desirable to set an upper limit for the amount of activity. Furthermore, since the time period during which the amount of activity increases also affects the quality of sleep, it is desirable to use the time change of the activity amount for sleep evaluation.

  The presentation control unit 118 uses the evaluation result of the comparison unit 117 to generate presentation information using the user's avatar A1 (or an appropriate character) as shown in FIG. To present. 8A shows an initial state, FIG. 8B shows a healthy state, FIG. 8C shows an unhealthy state, and FIG. 8D shows an insufficient sleep state. The display example shown in the figure is an example, and the type of classification and the form of display can be changed as appropriate.

  Further, since the processing unit 11 communicates with a server (not shown), the activity evaluation apparatus 30 is used by transmitting the avatar A1 (or the evaluation result of the comparison unit 117) generated by the presentation control unit 118 to the server. The avatar A1 can be viewed by a plurality of people. For example, it can be used for the purpose of watching the health of an elderly family living in a remote place with an avatar A1.

  Since this embodiment uses the measuring device 20 for the purpose of measuring the user's sleep state, the measurement device 20 may be configured to estimate the sleep state using information other than acceleration. As a technique for estimating a sleep state using information other than acceleration, a configuration in which a pressure sensor is provided in a bedding and a user's body movement is measured, and a camera that captures a moving image of the user during sleep is used and used. A configuration in which a person's movement is measured can be adopted as the measuring device 20. Moreover, you may employ | adopt for the measuring apparatus 20 the technique which estimates a sleep state from the breathing sound etc. during a user's sleep.

  In the activity evaluation device 30 of the present embodiment, the measurement device 20 includes a sleep sensor 212 that measures the sleep state of the user. Moreover, the process part 11 produces | generates the evaluation information regarding a user's sleep quality using the output of the sleep sensor 212. FIG. According to this configuration, the user can objectively know the state of sleep with confidence.

  Other configurations and operations are the same as those of the first embodiment, and the configurations denoted by the same reference numerals as those of the first embodiment have the same functions.

(Embodiment 3)
The activity evaluation device 30 according to the present embodiment evaluates the user's concentration using the output of the measuring device 20, and recovers the user's concentration when a decrease in the concentration is detected (that is, refresh). We propose a configuration to be used. That is, the measuring device 20 of this embodiment measures a user's mental activity.

  In order to measure the degree of concentration, a technique for extracting a feature amount from an image of a camera that captures a user, a technique for monitoring a user's brain activity, and the like can be considered. A technique is used to detect changes in the user's concentration by monitoring respiration. That is, the measuring device 20 includes a three-axis acceleration sensor 213 that monitors a user's body movement and respiration as shown in FIG.

  The measuring device 20 is configured to be attached to the user's trunk in order to monitor the user's body movement and respiration. That is, a configuration that is worn on the user's lower back, a configuration that is worn on the user's chest, or the like is employed as in the first embodiment.

  In general, it is known that when the user is concentrated, the body movement (particularly, the movement of the trunk) is reduced, and when the user is not concentrated, the body movement is increased. However, even if the user's arousal level decreases (that is, even if he / she becomes sleepy), the movement of the trunk will be small, so it is necessary to distinguish between a concentrated state and a state where the arousal level is low .

  Therefore, the user's breathing is also monitored. It is known that when the user's arousal level is low, the respiratory rhythm is regular, whereas when the user's arousal level is high, the respiratory rhythm is irregular. . That is, by monitoring respiration in addition to the user's body movement, it is possible to determine whether the user is concentrated or not. Here, a state in which the degree of concentration is reduced is interpreted as a state in which the degree of fatigue has increased.

  The output of the measuring device 20 is given to the processing unit 11 through the input unit 12 as shown in FIG. The processing unit 11 includes an analysis unit 161 that separates a component corresponding to the user's body movement and respiration from the vibration component output by the three-axis acceleration sensor 213. Further, the processing unit 11 includes a determination unit 162 that determines whether or not the user is concentrated using the body movement component and the respiration component separated by the analysis unit 161.

  As described above, the determination unit 162 determines the degree of body movement and the rhythm of breathing. That is, the determination unit 162 shifts from a state where the amplitude of body motion is smaller than a predetermined reference value to a large state during a period in which it is determined that the breathing rhythm is irregular, and this state continues for a predetermined time. If it continues, it will determine with having shifted from the state with a high concentration degree to the state where the concentration degree fell. This determination result becomes evaluation information regarding the mental activity of the user.

  When the presentation control unit 163 provided in the processing unit 11 receives evaluation information indicating that the user's concentration level has decreased from the determination unit 162, the presentation control unit 163 generates presentation information for refreshing the user. As the presentation device 40, a device that provides visual stimulation, auditory stimulation, olfactory stimulation, cold stimulation, or the like is used.

  For example, in order to give a visual stimulus, a lighting device capable of light control and color adjustment may be used as the presentation device 40. In the state where the degree of concentration is lowered, the presentation information is generated so as to realize a color tone that reduces the illuminance and calms the nerve such as green, blue, and purple. In addition, the presentation information is generated so as to realize a color tone that increases the illuminance and excites the nerve like red and yellow after a predetermined time has passed in this state. When the lighting device is used as the presentation device 40, the output unit 13 is configured to output an optical wireless signal similar to that of the remote control device that controls the lighting device.

  The visual stimulus can also be given by a device that displays an image, such as a television receiver, a display device of a personal computer, or a projector that projects an image. In this case, the presentation information is generated so as to display an image so as to excite the nerve after relaxing the user, as in the case of controlling the lighting device. Alternatively, when a user whose degree of concentration has been lowered is guided to another room, the presentation information is generated so as to display an image that gives a slight stress to the user in the separate room. An image that gives stress means an image in which adrenaline is secreted, such as an image as if skiing down or a roller coaster.

  In order to give a visual stimulus to the user, a simple planetarium may be used as the presentation device 40. In addition to the function of projecting a starry sky, the simple planetarium is known to have a configuration capable of projecting a still image or a moving image. When this type of presentation device 40 is used, a refresh effect can be expected.

  Auditory stimuli, olfactory stimuli, and cold stimuli can be used alone, but the effect is enhanced when combined with other stimuli.

  In the activity evaluation apparatus 30 described above, the measurement apparatus 20 includes a three-axis acceleration sensor 213 that is worn on the user's body. The processing unit 11 uses the output of the triaxial acceleration sensor 213 to generate evaluation information related to the user's concentration level or fatigue level. According to this configuration, the user can objectively know the concentration level or the fatigue level, which is a mental activity.

  Other configurations and operations are the same as those of the first embodiment, and configurations having the same reference numerals as those of the first embodiment have the same functions.

(Embodiment 4)
The activity evaluation device 30 of the present embodiment is configured to estimate the state of emotion as mental activity. As shown in FIG. 10, the measurement device 20 includes a brain activity sensor 214. The brain activity sensor 214 is configured to be wrapped around or put on the user's head, and may be configured to include an electrode for detecting electrical activity of the brain or to measure blood flow in the brain.

  In the present embodiment, emotional states are classified by combining the degree of comfort and the degree of arousal. The state of emotion is classified as shown in Table 2, for example.

感情の状態を表２に示すように分類するために、処理部１１は、脳活動センサ２１４の出力を用いて、快適の程度と、覚醒の程度とを推定する。すなわち、処理部１１は、入力部１２を通して受け取った脳活動センサ２１４の出力から脳活動に関する複数種類の生理指標を抽出する解析部１６４を備える。生理指標は、脳の部位ごとに脳活動の状態として抽出される。

In order to classify the emotional states as shown in Table 2, the processing unit 11 uses the output of the brain activity sensor 214 to estimate the degree of comfort and the degree of arousal. That is, the processing unit 11 includes an analysis unit 164 that extracts a plurality of types of physiological indices related to brain activity from the output of the brain activity sensor 214 received through the input unit 12. The physiological index is extracted as a state of brain activity for each part of the brain.

  The physiological index extracted by the analysis unit 164 is given to the estimation unit 165. The estimation unit 165 compares the data stored in the state storage unit 166 with the multiple types of physiological indices extracted by the analysis unit 164, and estimates the degree of comfort and arousal of the user. The state storage unit 166 stores a correspondence relationship between the degree of comfort and the degree of arousal and the physiological index. Therefore, the estimation unit 165 estimates the degree of comfort and arousal of the user as evaluation information using the physiological index extracted by the analysis unit 164 and the data stored in the state storage unit 166.

  The degree of comfort and the degree of arousal related to the user estimated by the estimation unit 165 are given to the presentation control unit 167. As shown in FIG. 11, the presentation control unit 167 plots the combination of the degree of comfort and the degree of arousal estimated by the estimation unit 165 on a plane having two levels of the degree of comfort and the degree of arousal. Generate presentation information. The plotted position is represented by a black circle on the plane. An emotional state is shown on the plane, and the emotional state of the user is indicated by the positional relationship between the plotted position and the emotional state.

  In the example shown in FIG. 11, the combinations of the degree of comfort and the degree of arousal are plotted for three users. Thus, in order to plot the combination of the degree of comfort and the degree of arousal for a plurality of people on the same plane, the presentation control unit 167 stores the emotional state of each person, It has a function to display the status at the same time. Note that the processing unit 11 may be configured to receive the outputs of the plurality of measuring devices 20 and estimate the emotional state corresponding to the outputs of the individual measuring devices 20. Even if this configuration is adopted, the emotional states of a plurality of persons can be displayed simultaneously on the same plane.

  The processing unit 11 may have a function of registering a user's face image. In this case, it is desirable that the processing unit 11 has a function of automatically generating a facial expression corresponding to the emotional state of the user using the facial image of the user during normal times. For example, the processing unit 11 extracts a dimension relating to a predetermined part from the user's face image, and performs image processing for adjusting the relationship of the extracted dimension according to the emotional state, thereby corresponding to the emotional state. Generate facial expressions.

  The presentation control unit 167 causes the presentation device 40 to display an expression corresponding to the emotional state on a screen that displays a plane representing the emotional state. However, the presentation control unit 167 may generate the presentation information so that the screen that displays the plane representing the emotional state and the screen that displays the facial expression corresponding to the emotional state are separate screens.

  As described above, since the present embodiment estimates the emotional state using the output of the brain activity sensor 214, the degree of concentration or the like as in the third embodiment can be estimated by estimating the emotional state of various people. In addition to being able to relate to the degree of fatigue, it can also be used as a game. For example, by comparing emotional states of people such as family members, friends, and colleagues, it can be used as a communication tool that provides a topic.

  By the way, motivation for intellectual work such as learning or work can be expressed as an emotional state. In Table 2 and FIG. 11, motivation is positioned in a state where the degree of comfort is relatively high and the degree of arousal is high. Since the motivation is quantitatively represented by a combination of the degree of comfort and the degree of awakening, the processing unit 11 obtains the degree of motivation using the degree of comfort and the degree of awakening as parameters. For example, in the example shown in FIG. 12, the degree of arousal (degree of arousal) is 73% and the degree of comfort (degree of comfort) is 88%, and the degree of motivation is determined to be 78% using both as parameters.

  FIG. 13 shows an example in which the estimated degree of motivation is displayed on the screen of the presentation device 40. Thus, since the motivation is quantified, a threshold can be set for the degree of motivation. In the illustrated example, the threshold is set to 50% or the like, and the motivation is reduced to 41%. Therefore, a program for improving the motivation is shown in the presentation device 40. That is, in the illustrated example, icons C <b> 1 to C <b> 4 for selecting “music”, “video”, “meditation”, and “enjoyment” are shown as the types of programs that improve motivation. When the user selects desired icons C1 to C4, the user can select a program that improves motivation. Note that when meditation is selected, for example, a breath-inducing rhythm sound is output.

  Also, on the screen shown in the figure, the time can be set. The time is the time for using the program selected by the icons C1 to C4, and it is possible to set either the time for using the program or the time for ending the program. When the type of program that improves the motivation is selected and the start button Bs is operated after setting the time to use the selected program, the content corresponding to the time to be used is selected from the corresponding program types.

  When a program that improves motivation is executed, it may be verified whether or not the motivation has improved. In the presentation device 40, a screen for verifying the improvement in motivation is configured as shown in FIG. 14, for example. The screen shown in the figure shows the degree of motivation obtained after executing the program in the upper part, and shows the change in the degree of motivation before and after the execution of the program in the lower part. Here, the processing unit 11 has a function of evaluating the degree of change in motivation.

  For example, the processing unit 11 sets conditions such as when the degree of motivation increases by 20% or when the degree of motivation becomes 80% or more, and when this condition is satisfied, the reward for the user's brain is paid. The given information is displayed on the screen of the presentation device 40. This information may be shown in words or figures that praise the user, for example. Further, when the degree of motivation increases, for example, as shown in FIG. 15, the rankings may be displayed in order of increasing degree or in order of increasing motivation after execution of the program. .

  Presenting this type of information to the presentation device 40 makes it possible to increase the motivation of the user and motivate the execution of a program that improves motivation. Further, the processing unit 11 records the degree of increase in motivation for each program executed by the user, and extracts a program having a high degree of increase in motivation for the user by analyzing the recorded data. Good. With this configuration, it is possible to preferentially present a program with a high degree of motivation for the corresponding user.

  In the configuration example described above, the degree of motivation was obtained using the degree of arousal and the degree of comfort as parameters. On the other hand, if other parameters that are not the degree of arousal and the degree of comfort are estimated based on the physiological index obtained from the output of the brain activity sensor 214, the degree of motivation is obtained using the other parameters. Is possible. For example, the degree of motivation can be obtained using three or more parameters.

  The processing unit 11 may estimate the degree of stress instead of the degree of arousal and comfort based on the physiological index output from the brain activity sensor 214. In this case, the state storage unit 166 stores data in which the physiological index extracted by the analysis unit 164 is associated with the degree of stress. The estimation unit 165 compares the physiological index extracted by the analysis unit 164 with the data stored in the state storage unit 166, and estimates the degree of user stress.

  When the degree of stress of the user is estimated in this way, the presentation control unit 167 may generate the presentation information so that a facial expression representing the degree of stress is displayed on the screen of the presentation device 40, for example. The example shown in FIG. 16 is a facial expression displayed on the presentation device 40 by such presentation information. In the illustrated example, the user avatar or an appropriate character is used, but various facial expressions may be generated by image processing using a photograph of the user's face.

  In the activity evaluation device 30 of the present embodiment, the measurement device 20 includes a brain activity sensor 214 that measures the brain activity of the user. The processing unit 11 uses the output of the brain activity sensor 214 to generate evaluation information related to the degree of comfort and the degree of arousal, and combines the degree of comfort and the degree of arousal, which are evaluation information, to thereby provide user emotions. Is generated as presentation information. According to this configuration, the user can objectively know the state of his / her emotion based on the brain activity which is a mental activity.

  Other configurations and operations are the same as those of the first embodiment, and configurations having the same reference numerals as those of the first embodiment have the same functions.

(Embodiment 5)

  The sensor 215 is formed in a glasses shape like a head-mounted display, and includes a display device 23 that presents video to the user and a camera 24 that captures the user's eyes E1 as shown in FIG. . In this configuration, by using the display content of the display device 23 and the state of the user's eyes E1 captured by the camera 24, the processing unit 11 generates evaluation information relating to the fatigue level and the aging level of the user. It becomes possible.

  In the present embodiment, an index is displayed on the display device 23, and the processing unit 11 includes an image processing unit 171 that extracts information about the eyes such as the pupil diameter of the user using an image captured by the camera 24. In this embodiment, the pupil diameter uses a width dimension in the left-right direction of the pupil. In addition, the processing unit 11 includes a video control unit 172 that generates video information for displaying video on the display device 23.

  The illustrated processing unit 11 includes an analysis unit 173 that observes a change in pupil diameter measured by the image processing unit 171 when the video control unit 172 presents a predetermined brightness index on the display device 23. The analysis unit 173 extracts information such as pupil contraction rate (pupil contraction rate), contraction speed or acceleration, pupil position fluctuation, and the like using the temporal change in pupil diameter as shown in FIG. In FIG. 19, time T1 represents the period during which the index is presented.

  The processing unit 11 includes a comparison unit 174 and a state storage unit 175. The state storage unit 175 stores data in which the miosis rate, the contraction speed or acceleration, the fluctuation of the pupil position, and the like are associated with the fatigue level and the aging level. The comparison unit 174 estimates the degree of fatigue and aging by comparing information such as the miosis rate, contraction speed or acceleration, and pupil position fluctuation obtained by the analysis unit 173 with the data stored in the state storage unit 175. To do.

  The fatigue level and the aging level estimated by the comparison unit 174 are presented to the presentation device 40 using an avatar or an appropriate character in the same manner as the avatar A1 (see FIG. 3) showing the health level in the first embodiment. That is, the presentation control unit 176 generates presentation information so that an avatar (or character) with a posture corresponding to the degree of fatigue and the degree of aging can be presented. Only one of the fatigue level and the aging level may be estimated. In addition, the presentation control unit 176 may have a function of generating meal content or a meal recipe as presentation information according to the degree of fatigue.

  In the configuration example described above, the degree of fatigue and the degree of aging are extracted using changes in the pupil diameter when an indicator of a predetermined brightness is presented on the display device 23, but the video displayed on the display device 23 is a predetermined image. In addition to the brightness index, various patterns can be adopted, and the display time and brightness can be set as appropriate. In addition, the information about the eyes extracted using the image captured by the camera 24 is not limited to the pupil diameter, and if information such as the direction of the line of sight and blinks is also extracted, the fatigue level and the aging level of the user are estimated. Can be performed with higher accuracy.

  In the present embodiment, the eyeglass-type sensor 215 is used. When the relative position with respect to the human eye can be fixed, the display device 23 and the camera 24 are selected from a smartphone, a tablet terminal, a game machine, or the like. It is possible to divert the display device and camera attached to the device to be used.

  In the activity evaluation apparatus of this embodiment, the measurement apparatus 20 includes a sensor 215 that measures a physiological index related to the user's eyes. The processing unit 11 uses the output of the sensor 215 to generate evaluation information related to the user's fatigue level and aging level. According to this configuration, the user can objectively know the fatigue level and the aging level.

  Other configurations and operations are the same as those of the first embodiment, and configurations having the same reference numerals as those of the first embodiment have the same functions.

In Embodiment 3, the example which displays the image | video which restores a concentration degree using the presentation apparatus 40 like a television receiver, a display apparatus, and a projector was shown. In this embodiment, as shown in FIG. 20, a head-mounted display 41 that is worn on the head of the user M1, and a sensation presentation device that gives a sensation of the hand being pulled by the user M1. 42 is used for the presentation device 40.

  The head mounted display 41 is assumed to be a see-through type. That is, the head mounted display 40 is configured so that not only the image displayed on the presentation device 40 can be seen but also the surroundings can be seen through the head mounted display 41. On the other hand, the sensory presentation device 42 incorporates an actuator including a weight that virtually gives a force sense.

  The processing unit 11 generates presentation information that simulates the state in which the animal is walked by the head mounted display 41 and the sensory presentation device 42. In other words, the appearance of the virtual animal A2 is displayed on the head mounted display 41, and a force sense pulled by the sensory presentation device 42 is generated according to the movement of the virtual animal A2 displayed on the head mounted display 41. Presentation information is generated.

  If the state where the animal is walked is simulated by the presentation device 40 and the presentation information described above, it is possible to impart entertainment properties and allow the user M1 to exercise. For example, the present embodiment can be adopted when it is desirable to increase the amount of activity of the user for improving the sleep state or when it is desirable to move the body for refreshing.

  In the present embodiment, since a state in which a pet is walked is simulated, the user is more motivated than taking a walk alone. The kind of animals to be walked can be arbitrarily selected, and even animals that cannot be kept generally such as lions can be walked, and the animals to be walked can be changed depending on the situation. is there. Since it is a virtual animal, size, personality, etc. can be selected. For example, in the case of an animal having a large size, the presentation information is generated so as to increase the force sense transmitted from the sensory presentation device 42. Also, if the personality is not enough, the presentation information is generated so as to be pulled slowly, and if the personality is active, the presentation information is generated so as to be pulled vigorously.

  Furthermore, if it is possible to see animals that other users are taking a walk with each other by wireless communication with the activity evaluation apparatus 30 of other users, the entertainment property can be further enhanced. Moreover, you may utilize the activity evaluation apparatus 30 of this embodiment so that a plurality of users may perform a virtual walk in a dedicated facility. This embodiment may be used in appropriate combination with the above-described embodiment.
