Abstract

The differences between the excessive attention and unfocused attention states were examined, as part of a development of an agent system and warning system that adapt to a driver's state. Eye movement was investigated to identify to what extent drivers used visual information, which was most important information for the drivers. An Eye-mark Recorder was used for eye-movement measurement, and a LEGACY Touring Wagon 3.0R equipped with an Active Driving Assist (ADA) system was used for the experiment. The eye behaviors of the subjects were categorized, and an F-test was performed for the data for the start and the end of driving without a leading vehicle. The acceleration and the steering angular velocity of the vehicle were calculated to examine whether the variance of eye-movement was affected by the driving environment and the driver's behaviors. The variance of the eye-movement successfully identified the transition from the excessive attention to unfocused attention.
