Drivers' Visual Atttention to In-Vehicle Displays: Effects of Display Locationand Road Type

摘要

The purpose of this report is to describe two experiments concerning theattentional demand of in-vehicle displays while driving on public roads. In the first experiment, 10 younger and 12 older drivers participated on an expressway, a rural road, and a suburban street. Their glances to the instrument cluster, the center console, and a head-up display were recorded by an eye-mark recorder. They were instructed to look at the targets as much as safely possible. In the second experiment, another 8 younger drivers' visual behavior relative to the smae targets, on urban streets, was recorded by a small video camera. Vehicle operation data (speed, steering-wheel angle, and throttle-opening ratio) were recorded in both experiments. The results of both experiments showed that drivers' glance behavior relative to in-vehicle displays was affected by the display location and the road type.
