Measurement device and measurement method
A measurement device includes an ear canal connection configured to be inserted into an ear canal, a shaft extending from the ear canal connection along an insertion direction, a biological sensor configured to be turnable about the shaft relative to the ear canal connection and a controller configured to measure the biological information based on a biometric output obtained from the biological sensor.
1. A measurement device, comprising:
an ear canal connection configured to be inserted into an ear canal;
a shaft extending from the ear canal connection along an insertion direction;
a biological sensor configured to be turnable about the shaft relative to the ear canal connection; and
a controller configured to measure biological information based on a biometric output obtained from the biological sensor.
2. The measurement device according to claim 1 , further comprising:
a sensor disposing part configured to be turnable about the shaft relative to the ear canal connection, wherein
the biological sensor is disposed on an outer periphery of the sensor disposing part.
3. The measurement device according to claim 1 , further comprising:
a sound generator; and
a sensor disposing part that is disposed on an outer peripheral side of the shaft and has the biological sensor disposed on the outer periphery, wherein
the shaft transmits sound generated by the sound generator; and
the sensor disposing part is turnable about the shaft relative to the ear canal connection.
4. The measurement device according to claim 1 , wherein,
when the biometric output is not within an allowable range that can be used for measurement of the biological information, the controller allows a notification unit to notify that the biological sensor is needed to be turned.
5. The measurement device according to claim 4 , wherein,
when the biometric output is within the allowable range, the controller adjusts a measured intensity of the biometric output in the biological sensor.
6. A measurement method by a measurement device comprising a biological sensor configured to be turnable about a shaft extending from an ear canal connection along an insertion direction relative to the ear canal connection,
the method comprising a notification step in which, when a biometric output obtained from the biological sensor is not within an allowable range that can be used for measurement of biological information, a notification indicating that the biological sensor is needed to be turned is provided.
