摘要

This light-of-sight data processing device is provided with: an inflection point detection unit which detects an inflection point of the trajectory of a line of sight on the basis of line-of-sight data obtained by detecting the line-of-sight of a subject for a prescribed period; a start point determination unit which, when the inflection point is detected, determines whether the line of sight moves by equal to or greater than a first movement amount within a first time between the inflection point and the start point at which the movement starts towards the inflection point; an end point determination unit which, when the inflection point is detected, determines whether the line of sight moves by equal to or greater than a second movement amount within a second time between the inflection point and an end point at which the movement ends from the inflection point; and an abnormal data detection unit which detects abnormal data in the line-of-sight data on the basis of the determination results from the start point determination unit and the end point determination unit.
