Abstract

Analyses of optic flow due to observer self-motion and analyses ofthe driver’s gazing behavior during curve driving have suggested that the driverhas a tendency to look at a location close to the tangent point on the inside edge ofthe road. Psychophysical experiments have further demonstrated that this visualstrategy can be partly explained as an optimization of information pick-up. Themain objective of the present study was to investigate, in an interactive simulationcontext, if this perceptual strategy might be used to define a visual aid for curvedriving. In the framework of the French ARCOS project (Research action forsecure driving; www.arcos2004.com), we used a mini-simulator developed byINRETS (MSIS-CIR group) in collaboration with FAROS company, with twomain original characteristics: (1) during curve driving, the tangent point can becalculated and inserted in the visual scene in real-time and (2) a real-time eyerecordingsystem (EYELINK,® SMI) allows us to evaluate the relationshipsbetween driving performance, gaze direction and the on-line presentation of thetangent point.

Gaze Behavior During Simulated Driving: Elements for a Visual Driving Aid
