Abstract
A measurement device that includes a calculation unit that calculates, using sensor data measured by a sensor according to a measurement motion regarding a limb of a user, the sensor being attached to the user at a predetermined attachment site, a length and a central angle of an arc related to a trajectory of the sensor in a period of the measurement motion, and an estimation unit that estimates a radius of the arc calculated using the calculated length and the calculated central angle of the arc as a length of the limb of the user.
Claims7
A measurement device comprising:
- a memory storing instructions;
- and
- a processor connected to the memory and configured to execute the instructions to:
- calculate, using sensor data measured by a sensor according to a measurement motion regarding a limb of a user, the sensor being attached to the user at a predetermined attachment site, a length and a central angle of an arc related to a trajectory of the sensor in a period of the measurement motion;
- and
- estimate a radius of the arc calculated using the calculated length and the calculated central angle of the arc as a length of the limb of the user.
A measurement method executed by a computer, the method comprising:
- calculating, using sensor data measured by a sensor according to a measurement motion regarding a limb of a user, the sensor being attached to the user at a predetermined attachment site, a length and a central angle of an arc related to a trajectory of the sensor in a period of the measurement motion;
- and
- estimating a radius of the arc calculated using the calculated length and the calculated central angle of the arc as a length of the limb of the user.
A non-transitory recording medium storing a program for causing a computer to execute:
- calculating, using sensor data measured by a sensor according to a measurement motion regarding a limb of a user, the sensor being attached to the user at a predetermined attachment site, a length and a central angle of an arc related to a trajectory of the sensor in a period of the measurement motion;
- and
- estimating a radius of the arc calculated using the calculated length and the calculated central angle of the arc as a length of the limb of the user.
