Abstract
Drivers’ visual distraction serves as the main cause of traffic accidents, different ambient illuminance can also exert a considerable impact on the drivers’ cognition efficiency. It is therefore very important to study the color visibility of AR-HUD interface under different illuminance. In this study, an evaluation experiment of digital character was carried out through an in-vehicle AR-HUD based on three variables: seven colors (R, G, B, Y,P, YR, W) of character, the outlines(white, grey, none) of character and ambient illuminance(daytime, night). A total of 19 stimuli were displayed to evaluate color visibility, visual fatigue, color preference and visual intrusion. The experimental results showed that (1): Y (4.12) and G (3.92) had apparent visibility in daytime, while R (3.88) and Y (3.80) were significantly obvious in night. (2): For the outlined character, the visibility with white outline is higher than that of grey outline, and visibility is affected by the luminance contrast between character and outline. (3): For the non-outlined character, windshield turns into the display background, the luminance contrast of character reaches greater visibility.
