A Displaying Method for the On-board Display Reflected Driving Environmental Variation

Abstract

With the increasing number of on-board visual displays, it is important to develop such on-board displays as easy to see even in various driving environments, such as driving on a snow covered. In this paper, we propose a new displaying method based on luminance adaptation, one of the human vision properties, associated with luminance changes while driving. In this method, adaptation level of the driver is estimated with the luminance of inside and outside of the vehicle. Then, the luminance of the display is determined by the adaptation luminance in order to perceive the constant brightness of the display even in the different environmental luminance. Experimental results of subjective evaluation comparing the conventional display indicate the effectiveness of the method.
