Abstract
Generally, when a driver looks at an in-vehicle display device, the driver will often repeatedly look at the display device for short durations while glancing back at the road for safety rather than look once for a long time. In this study, authors investigated the influence of driving load on the characteristics of information acquisition method by having 11 subjects drive a passenger car while they repeatedly read display information on a test course. The results indicate that while driving a car in a leeway condition the psychological load during the time not looking at the display device (i.e. the time between repeated readings) does not greatly disturb the information acquisition performance.
