Abstract
This study describes depth perception to visual contents in various distances when using 3D Head-Up Display which places virtual images on the appropriate 3D position. In the field experiment, the 3D-HUD was evaluated in comparison with two types of HUD which have focal depth of 7 and 15 meters. The visual contents were displayed ahead from 30 to 100 meters and participants were instructed to judge the depth of contents while performing a visual primary task. Judgement time and error were measured during the experiment. Based on the results, we discuss how the depth perception is influenced by each HUD.
