Title:
DRIVING ANALYSIS DEVICE, AND DRIVING ANALYSIS METHOD
Document Type and Number:
WIPO Patent Application WO/2021/112048
Kind Code:
A1
Abstract:
An information generating unit (S10 to S40) generates a time series of detected elements, where a gaze direction, indicating the region, among a plurality of regions, toward which the gaze of a driver driving a vehicle is oriented, and the open or closed state of the eyes of the driver, serve as the detected elements. An acquiring unit (S50) acquires evaluation data from the time series of the detected elements, using a time window having a predetermined time width. An extracting unit (S60) extracts, from the evaluation data, a plurality of feature quantities including, at least, a result obtained by adding together the frequency of appearance of each detected element. An analyzing unit (S70) analyzes at least one of the inclination of the driver and the state of the driver using a function which takes as inputs at least some of the plurality of feature quantities extracted by the extracting unit.
