And the configured sensor 2. Each part of the circuit board 50 and the sensor 2 operate by power supply from the battery 55.

  The circuit board 50 and the battery 55 are accommodated in the first portion 12 of the first housing 10. The control unit 51 is an arithmetic processing unit such as a central processing unit (CPU) or a microprocessor, for example, controls the operation of each unit in the living-body-type detection device 1, detects the operation of the living body based on the detection result of the sensor 2, And processes such as transmission and reception of data of detection results. Storage unit 52 is configured using a non-volatile memory element such as a flash memory or an EEPROM (Electrically Erasable Programmable Read Only Memory), and stores data of the detection result and the like given from control unit 51.

  The connection terminal 53 can connect, for example, a communication cable of USB (Universal Serial Bus) standard. When a communication cable is connected to the connection terminal 53, for example, the control unit 51 can transmit and receive data to and from an external device via the communication cable. Further, for example, when the battery 55 is a rechargeable battery, the battery 55 can be charged by the power supplied through the communication cable connected to the connection terminal 53.

  The wireless communication unit 54 can perform wireless communication with an external device in accordance with a communication standard such as wireless LAN (Local Area Network) or Bluetooth (registered trademark), for example. The wireless communication unit 54 transmits the data for transmission given from the control unit 51 to an external device, and gives the data received from the external device to the control unit 51. Thereby, the control unit 51 can transmit the detection result of the movement of the predetermined part of the living body or the detection result of the operation of the living body to the external device with the external device.

  The sensor 2 is a sensor that outputs an electrical signal according to the distance to the object by receiving the light emitted from the light emitting unit as described above and reflected by the object by the light receiving unit. The sensor 2 is connected to the circuit board 50 via a flexible communication cable, and the output signal of the sensor 2 is given to the control unit 51. The control unit 51 performs a process of detecting the presence or absence of the movement of the object based on the signal from the sensor 2.

  The living-worn detection device 1 according to the present embodiment is configured so that the light from the sensor 2 is irradiated to a predetermined part of the human body (the first detection area 101 or the second detection area 102 described above). It is attached to 100. The sensor 2 emits light to a predetermined part of a human body and receives a reflected wave thereof, thereby outputting an electric signal according to the distance to the predetermined part to the control unit 51 of the circuit board 50.

The movement of the part can be detected.

  The control unit 51 stores, for example, the distance acquired from the sensor 2 and calculates a change in distance by comparison with the previous distance. The control unit 51 compares the change in distance in a predetermined period, and determines that the point of change when the amount of change switches from increasing to decreasing or decreasing to increasing is the peak of the change. When the control unit 51 detects the peak of the distance change, the control unit 51 compares the amount of change in the current peak with the amount of change in the previous peak, and determines whether the difference exceeds a threshold. The control unit 51 determines that the crawling operation has been performed when the difference between the peak change amounts exceeds the threshold. However, when it is determined that the predetermined time has not elapsed since it was determined that the chewing operation was performed last time, the control unit 51 determines that the peak is not the chewing operation. The control unit 51 determines the presence or absence of the eyelid movement according to the change of the distance acquired from the sensor 2 in this manner, measures the number of times the eyelid movement is performed, and stores the measurement result as the eyelid information in the storage unit 52 Do.

The variable N is realized using, for example, a storage element such as a register included in the control unit 51. First, the control unit 51 obtains an output signal of the sensor 2 by sampling (step S2). The control unit 51 calculates the distance to a predetermined location of the human body wearing the living-body-worn detection device 1 based on the acquired signal value of the sensor 2 and stores the calculation result in the storage unit 52 (step S3) . The control unit 51 compares the distance calculated in step S3 with the distance calculated and stored last time, and calculates the change in the distance by calculating the difference (step S4).

  The control unit 51 compares the changes calculated so far in time series, and determines whether the change calculated this time corresponds to the peak of the change (step S5). When it is not the peak of change (S5: NO), the control unit 51 returns the process to step S2. If it is determined that the current change is a peak (S5: YES), the control unit 51 calculates the difference between the current change and the previous change of the peak, and determines whether this difference exceeds a threshold. (Step S6). If the difference does not exceed the threshold (S6: NO), the control unit 51 returns the process to step S2. If the difference exceeds the threshold (S6: YES), the control unit 51 determines whether a predetermined time has elapsed since it was determined that the mastication operation was performed last time (step S7). When the predetermined time has not elapsed from the last chewing operation (S7: NO), the control unit 51 returns the process to step S2.

  If the predetermined time has elapsed since the last chewing operation (S7: YES), the control unit 51 adds 1 to the value of the variable N (step S8). Next, the control unit 51 determines whether or not the measurement of the number of chewings is finished (step S9). When measurement is not completed (S9: NO), the control unit 51 returns the process to step S2 and repeats the above-described process. When the measurement is finished (S9: YES), the control unit 51 generates the habit information including the number of mastications which is the measurement result and the related information such as the change of the distance if necessary, and stores it in the storage unit 52 (Step S10), and the process ends.
