Abstract

We conducted experiments to investigate the effect of display positions and orientations on visibility of in-vehicle display systems. In experiments, we installed display devices (tablet PCs) onto nine typical visual target positions on a vehicle (e.g., meter panel, left, right and inner mirrors, etc.) and evaluated visibilities of those devices under three illumination conditions (night, twilight, daylight). We employed RDK (Random Dot Kinematogram) as visual stimuli and determined PSE (Point of Subjective Equality) for displayed stimuli sizes between two devices (one is on the HUD (Head Up Display) position as a reference stimuli and another one is on one of nine devices including the HUD position itself.) through staircase procedures. Experimental results show that PSE for the left-mirror position device is significantly higher than PSE for other devices. Also, comparing PSE at door mirror positions with ones at positions where CMS (camera monitoring system) displays will be installed (just inside doors), we found visibility at latter position is better for the left side positions.
