Experimental Study on Superiority of Automotive Head-Up Displays in Visual Optics.

Abstract

Automotive head-up displays (HUDS) are superior to conventional console displays for use in recognizing forward view and displayed images. By analyzing the visual performance of drivers, the authors have experimentally proven the superior mechanism of HUD from the point of visual optics. The authors have concluded that the peripheral field of vision plays an important role in recognizing displayed images, while external visual objects are watched from automobiles. In the paper, the authors have also proven a hypothesis that can determine the balance of eye fixation time on the external objects and displayed images, and differences in degree of displayed image recognizability between HUD and conventional displays.
