自動車運転中のディスプレイの視認性計測

抄録

With the proliferation of on-board information in recent years, vehicle display devices, such as navigation system, have multiplied and instrument panels have become very complex. Still, a driver must be able to see and understand the information. For safe and comfortable driving, there are increasing demands for improving visibility of the onboard display. There have been various reports for visibility of the display. But, most of the reports have been on the evaluation by human sense, and there has been few for the visibility evaluation during vehicle driving.
This paper describes the method for detecting the driver's eye movements using the facial images illuminated by infrared light source with a single TV camera on dashboard, measuring the gaze duration and evaluating visibility in driving. In addition, the usefulness of the navigation system with voice route guidance compared with a conventional non-voice system has been demonstrated using the measuring system based on this method by day and by night.
