  Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1)
A first embodiment of the present invention will be described with reference to FIGS. The posture discriminating apparatus according to the present embodiment includes posture information measuring devices 1a and 1b disposed in front of the left and right shoes 30a and 30b worn by the person A to be measured as shown in FIGS. The posture information measuring devices 1a and 1b are each formed in a sheet shape, and are used on the soles of the shoes 30a and 30b.

  As shown in the schematic block diagram of FIG. 1A, one posture information measuring device 1a includes an arithmetic processing unit 2a configured by, for example, a microcomputer, an acceleration sensor 3a that measures acceleration applied to the mounting site, and a mounting A short distance between the magnetic direction sensor 4a for detecting the magnetic direction of the part and the other posture information measuring device 1b or a personal computer (hereinafter abbreviated as a personal computer) PC by a communication method such as infrared communication or Bluetooth. For example, a wireless communication unit 5a that performs wireless communication, a notification unit 6a that performs a notification operation by outputting a buzzer sound or a voice message, a storage unit 7a that includes a RAM and a ROM, a battery as a power source, A power supply circuit unit 8a to be supplied and a timer unit 9a for providing time information to the arithmetic processing unit 2a are provided as main components. That. The arithmetic processing unit 2a includes a comparison function unit 11 that compares the posture information measured by the measuring device 1a and the posture information measured by the posture information measuring device 1b.

  In addition, as shown in the schematic block diagram of FIG. 1B, the other posture information measuring device 1b includes an arithmetic processing unit 2b configured by, for example, a microcomputer, and an acceleration sensor 3b that measures acceleration applied to the wearing site. A wireless communication unit 5b that performs short-distance wireless communication by a communication method such as infrared communication or Bluetooth between the magnetic direction sensor 4b that detects the magnetic direction of the wearing part and the posture information measuring device 1a, a RAM, and a ROM The main configuration includes a storage unit 7b comprising: a power supply circuit unit 8b for supplying operation power to an internal circuit using a battery as a power source; and a time measuring unit 9b for supplying time information to the arithmetic processing unit 2b.

  Here, since one posture information measuring device 1a is disposed in the right foot shoe 30a and the other posture information measuring device 1b is disposed in the left foot shoe 30b, the posture information measuring devices 1a and 1b respectively. The posture information of different parts of the body of the person to be measured can be measured as the same kind of physical quantity. Here, the first posture information measuring means is constituted by the acceleration sensor 3a and the magnetic direction sensor 4a included in one posture information measuring device 1a, and the acceleration sensor 3b and the magnetic direction sensor 4b included in the other posture information measuring device 1b. Second attitude information measuring means is configured.

  Next, the posture determination operation by the posture determination device of this embodiment will be described. The arithmetic processing unit 2a of the posture information measuring device 1a performs a posture information capturing process every time a predetermined measurement period elapses based on the time information input from the time measuring unit 9a. Measurement data is acquired from the magnetic orientation sensor 4a, the measurement data of both sensors 3a and 3b are stored in the storage unit 7a, and a transmission request for measurement data is sent from the wireless communication unit 5a to the attitude information measuring device 1b.

  On the other hand, in the attitude information measuring device 1b, the arithmetic processing unit 2b constantly monitors the reception state of the wireless communication unit 5b. When the wireless communication unit 5b receives a data transmission request from the attitude information measuring device 1a and outputs the data transmission request to the arithmetic processing unit 2b, the arithmetic processing unit 2b performs measurement from the acceleration sensor 3b and the magnetic direction sensor 4b based on the data transmission request. The data is taken in, and the taken measurement data is stored in the storage unit 7b, and the measurement data of both sensors 3b and 4b is returned from the wireless communication unit 5b to the requesting posture information measuring device 1a.

  At this time, in the posture information measuring device 1a that requested the measurement data, the wireless communication unit 5a receives the measurement data from the posture information measuring device 1b, and the arithmetic processing unit 2a receives the acceleration sensor 3b received by the wireless communication unit 5a and The measurement data of the magnetic direction sensor 4b is stored in the storage unit 7a. Then, the comparison function unit 11 of the arithmetic processing unit 2a compares the measurement data of the acceleration sensor 3a and the magnetic direction sensor 4a read from the storage unit 7a with the measurement data of the acceleration sensor 3b and the magnetic direction sensor 4b, respectively. When the deviation of the measurement data of the sensors 3a and 3b exceeds a predetermined threshold value, or when the deviation of the measurement data of the magnetic direction sensors 4a and 4b exceeds a predetermined threshold value, a notification command is output to the notification unit 6a. Then, a notification operation is performed in real time by outputting a buzzer sound or a voice message from the notification unit 6a.

  Here, when the person A to be measured is seated or standing in a correct posture, as shown in FIG. 4A, the right foot shoe 30a is arranged on the right side and the left foot shoe 30b is arranged on the left side. Also, since the shoe Da directions Da and Db of the shoes 30a and 30b are substantially the same, the measurement data measured by the acceleration sensor 3a and the magnetic orientation sensor 4a of the posture information measuring device 1a for the right foot, and the posture for the left foot The measurement data measured by the acceleration sensor 3b and the magnetic orientation sensor 4b of the information measuring instrument 1b are substantially the same value. Therefore, when the comparison function unit 11 compares the measurement data of the sensors 3a and 4a provided on the right foot shoe 30a with the measurement data of the sensors 3a and 4a provided on the left foot shoe 30b, the difference between the two is predetermined. Since it becomes smaller than the threshold value, the arithmetic processing unit 2a does not perform the notification operation.

  On the other hand, as shown in FIG. 4B, when the person A to be measured is sitting with his / her legs crossed with his left foot down and right foot up, when viewed from vertically above, the direction of the shoe tip of the shoe 30a Since Da crosses diagonally with respect to the shoe tip direction Db of the shoe 30b, the deviation between the measurement data of the magnetic direction sensor 4a and the measurement data of the magnetic direction sensor 4b becomes larger than the correct posture. Further, the shoe 30b for the left foot that is in contact with the floor surface has the shoe tip facing in a substantially horizontal direction, whereas the shoe 30a for the right foot that is floating in the air has the shoe tip facing upward or downward from the horizontal plane. Therefore, the difference between the measurement data of the acceleration sensor 3a and the measurement data of the acceleration sensor 3b becomes larger than the correct posture. Therefore, if the above threshold value is set to a value smaller than the displacement of the acceleration sensors 3a, 3b or the magnetic azimuth sensors 4a, 4b generated when the feet are assembled, the state where the feet are assembled Then, since the displacement of the acceleration sensors 3a and 3b or the displacement of the magnetic azimuth sensors 4a and 4b is equal to or greater than the threshold value, a notification command is output from the comparison function unit 11 to the notification unit 6a, and the notification unit 6a performs a notification operation. Is done.

  Thus, according to the posture discriminating apparatus of the present embodiment, the posture information measuring devices 1a and 1b each measure posture information of different parts of the body of the person A to be measured. When the posture information measured by the posture information measuring devices 1a and 1b deviates by a predetermined threshold or more according to the posture change, the comparison function unit 11 outputs a notification command, and the notification unit 6a or the activity meter 20 Since the notification operation is performed, the measurement subject A can be informed of the change in posture, and as a result, the measurement subject A can be encouraged to maintain a good posture. In the present embodiment, when the person A to be measured changes from the correct posture, for example, when the person A is crossed, the comparison function unit 11 detects the change, and the notification unit 6a performs the notification operation. Therefore, the subject A can be informed of the change in posture, and the subject A can be encouraged to maintain the correct posture. Further, in this embodiment, when the comparison function unit 11 determines that the person A to be measured is crossed, the notification unit 6a performs the notification operation, so the person A is crossed with the person A to be measured. You can be informed that you are out and encourage you to maintain a good posture.

  In addition, in the arithmetic processing unit 1a of the posture information measuring device 1a, when the preset time comes every day, the measurement data stored in the storage unit 7a is transmitted from the wireless communication unit 5a to the personal computer PC. Detailed analysis such as changes in posture of the day can be performed.

(Embodiment 2)
In the first embodiment, the posture information measuring devices 1a and 1b are attached to the left and right shoes 30a and 30b, whereas in this embodiment, the person A to be measured is shown in FIGS. 5 (a) and 5 (b). One posture information measuring device 1a is attached to the upper portion of the back portion of the outerwear 31 where the wearer wears, and the other posture information measuring device 1b is attached to a predetermined position from the middle portion to the lower portion of the back portion of the outerwear 31.

  Since the configuration of the posture information measuring devices 1a and 1b is the same as that of the first embodiment, the description thereof will be omitted, and the posture determination operation according to the present embodiment will be described below. The arithmetic processing unit 2a of the posture information measuring device 1a performs a posture information capturing process every time a predetermined measurement period elapses based on the time information input from the time measuring unit 9a.

The measurement data is stored in the storage unit 7a. Then, the comparison function unit 11 of the arithmetic processing unit 2a compares the measurement data of the acceleration sensor 3a read from the storage unit 7a with the measurement data of the acceleration sensor 3b, and the deviation of the measurement data of the acceleration sensors 3a and 3b is predetermined. When the threshold value is exceeded, a notification command is output to the notification unit 6a, and a buzzer sound and a voice message are output from the notification unit 6a, thereby performing a notification operation in real time.

  Thus, according to the posture discriminating apparatus of the present embodiment, the posture information measuring devices 1a and 1b each measure posture information of different parts of the body of the person A to be measured. When the posture information measured by the posture information measuring devices 1a and 1b deviates by a predetermined threshold or more according to the posture change, the comparison function unit 11 outputs a notification command, and the notification unit 6a or the activity meter 20 Since the notification operation is performed, the measurement subject A can be informed of the change in posture, and as a result, the measurement subject A can be encouraged to maintain a good posture.

In the present embodiment, the comparison function unit 11 compares the acceleration applied to the upper part of the back of the person A to be measured with the acceleration applied to a predetermined part from the middle part to the lower part of the person A's back. Since the comparison function unit 11 determines that the back of the person A to be measured is bent when the measurement result of is deviated by a predetermined threshold value or more, the notification unit 6a or the activity meter 20 performs the notification operation. The person A can be informed that his / her back is bent, and can be urged to maintain a good posture.

  Also in the present embodiment, the arithmetic processing unit 1a of the posture information measuring device 1a transmits the measurement data stored in the storage unit 7a from the wireless communication unit 5a to the personal computer PC when a preset time comes every day. The personal computer PC can perform detailed analysis such as changes in the posture of the day.
