Abstract
Cognitive tunneling is a phenomenon where a driver can become overly‐focused on a display rather than the actual road scene. With a standard Head up Display (HUD), this is not normally an issue as the image is typically lower than the direct road scene. Augmented Reality (AR) HUDs on the other hand, use conformal graphics which exactly overlay and highlight the outside environment and are directly in the road scene. Studies have shown that HUD graphics directly in the view of the driver can increase cognitive tunneling. In this paper, we will study whether reducing the image distance of the HUD can help reduce the occurrence of cognitive tunneling.
