Document Type and Number:
WIPO Patent Application WO/2023/170948
Kind Code:
A1
Abstract:
In the present invention, in order to measure sensor data relating to movement of a foot irrespective of the direction in which a sensor is mounted, a gait measurement device comprises: an acquisition unit for acquiring sensor data measured by a sensor mounted on footwear; a mounting-direction-determining means for determining, using the acquired sensor data, the direction in which the sensor is mounted; a coordinate conversion unit for converting the coordinate system of the sensor data in accordance with the determined direction in which the sensor is mounted; a detection unit for detecting a walking event from time-series data of the sensor data in which the coordinate system has been converted; a calculation unit for calculating a gait parameter according to the detected walking event; and a transmission unit for transmitting the calculated gait parameter.
