CAUTION AREA ESTIMATING SYSTEM AND METHOD

WIPO Patent Application WO/2007/086222

A1

A system (10) for estimating a caution area with high accuracy independently of the mental state of the user. The system (10) comprises means (11, 17) for detecting the line of sight of the user, means (13, 21) for detecting bioinformation on the autonomic nerve system of the user, means (19) for estimating a line of sight stay model representing the degree at which the line-of-sight of the user stays in the field of view by analyzing the distribution of the line of sight of the user determined by the direction of the line of sight by using a statistical learning scheme, means (23) for estimating the arousal level on the basis of the bioinformation, and means (25) for estimating a caution area according to the parameter of the line-of-sight stay model and the arousal level.
