Abstract

The optimal display distance for a head up display showing augmented reality (AR-HUD) was investigated, based on visual cognition time and subjective assessment values of visibility. The tendency was that the further the display distance, the shorter the cognition time and the better the subjective assessment value. For display ranges of some length or further, improvements in both indices levelled off (reached saturation). We propose that the optimal display distance for AR-HUD systems is 15 m or more, the distance at which both indices reach saturation. .
