ヘッドアップディスプレイ（HUD）の投影方法がヒトの視覚情報処理に与える影響の評価

抄録

Head-up display (HUD) is a technology that is expected to be applied to automotive driver assistance. While driving, drivers input visual information into their brains by turning their eyes from the road environment to the HUD image. We investigated whether the time required for this eye-turning process is influenced by the HUD projection method. We found that the virtual image projection tended to take longer than the real image projection. The reason is probably that the positional relationship between the display body and the HUD image affected the spatial localization of the image.
