判定装置、判定方法、およびプログラム
Document Type and Number:
Japanese Patent JP7078177
Kind Code:
B2
Abstract:
A determination device includes: a sensor data reception unit that receives sensor data including acceleration in a travel direction of a user and in a gravity direction; a walking state discrimination unit that switches to a discrimination mode in response to the acceleration in the gravity direction exceeding a first threshold in a power saving mode, and switches to a walk measurement mode in response to the acceleration in the travel direction exceeding a second threshold in the discrimination mode; a change trend detection unit that detects a change trend of peak values using log data of the peak values of the acceleration in the travel direction in the discrimination mode; a threshold change unit that changes the second threshold based on a detection result by the change trend detection unit; and a transmission unit that transmits the sensor data in the walk measurement mode.
