Secondary task boundaries influence drivers' glance durations

Abstract

Drivers show a wide range of behavior while performing a secondary task behind the wheel. In the current study, we categorized drivers into groups based on their glance behavior at task boundary (i.e., pressing a touch screen button after reading driving-related messages) and compared driving capabilities of drivers in each group. The comparison between the groups identifies different eye glance strategies, or task switching decisions, and associated vehicle control behaviors. Senders' uncertainty model was adapted to explain the results and to suggest future directions in developing driver models.
