Title:
INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND INFORMATION PROCESSING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2018/116476
Kind Code:
A1
Abstract:
An Internet of Things (IoT) device according to the present invention detects variation in the movement direction of a pedestrian wearing the IoT device. While the amount of variation in the movement direction is below a threshold, the IoT device detects the per-step movement amount of the pedestrian from a vertical amplitude component of the IoT device. The IoT device uses the estimated movement amount to estimate the position of the pedestrian. Subsequently, if the amount of variation in the movement direction reaches or exceeds the threshold, the IoT device uses the movement amount detected while the estimated variation amount was below the threshold to estimate the position of the pedestrian.
