Abstract
Graphic display is an effective device for an automobile driver to get information. A driver, however, must pay attention to the outer environment, so there is not enough time to see the display. This paper describes an effective method of presenting graphic information to an automobile driver.
First, the graphic display is activated by fixation of the driver. The visual performance is measured by image processing of the driver's face. The driver's line of vision is detected by a position of the eye.
Second, optimum quantity of displayed information is determined by a model of a human visual information processing. The model describes the relationship between complexity of a displayed image and required time for the driver to understand it. Graphic image is designed by this model, so that the driver can get the information at a glance.
