Document Type and Number:
Japanese Patent JP7173294
Kind Code:
B2
Abstract:
This walk discrimination device is provided with: a data reception unit for receiving sensor data that includes an acceleration and an angular speed acquired by a sensor provided to a shoe in order to measure the walk of a pedestrian for each single step on the basis of the sensor data; an acceleration determination unit for determining whether the acceleration included in the sensor data is positive or negative; an attitude angle calculation unit which calculates an attitude angle using the acceleration and the angular speed included in the sensor data; an attitude angle determination unit which determines whether or not the attitude angle calculated by the attitude angle calculation unit has exceeded a threshold value and determines whether or not a peak of the attitude angle has been detected; a walk discrimination unit which discriminates a walk on the basis of a sequence of the determinations made by the acceleration determination unit and the attitude angle determination unit; and an output unit which outputs a discrimination result provided by the walk discrimination unit.
