The HUD is displayed directly in front of the driver to facilitate quick reading of information. However, because the display image overlaps with the scenery in front, it can be troublesome for the driver. It is thought that the HUD might better be displayed at a position removed from the line of vision extending straight forward.
We carried out tests in order to determine a display position in which there is no feeling of troublesomeness for the driver. The observers were required to assign one of five levels of troublesomeness to the HUD. The collected data was used to derive the basic relationship between the display position and the feeling of troublesomeness. The influence of the height of the driver's eye position on the feeling of troublesomeness was also analyzed. It is estimated that the drivers with low eye positions would feel much troublesomeness caused by the HUD.
