Abstract: A detection device that includes an extraction unit that extracts waveform data based on a gait of a walker using sensor data acquired from a sensor installed on a foot of the walker and a detection unit that detects a gait event from the waveform data extracted by the extraction unit.

Abstract: Provided is an information processing device including an acquisition unit configured to acquire load information based on a load applied to a load measurement device from a sole of a user and a feature amount extracting unit configured to extract a feature amount indicating a walking environment from time series data in at least one walking cycle included in the load information.

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 o
