The use of head-up displays (HUDs) in motor vehicles.

摘要

Motor vehicle manufacturers are installing Head-Up Displays (HUDs) in motor vehicles. HUDs are used to provide drivers with a variety of vehicle information such as vehicle speed. In theory, HUDs should assist drivers in monitoring the status of their vehicle while allowing them to spend more time looking at the external scene. However, research in the aviation literature has shown that pilots tend to cognitively tunnel on HUDs to the extent that processing of the external scene is delayed. In the present research, a driving simulator was used to examine whether cognitive tunnelling occurs with analogue and digital HUDs. This experiment showed that participants were better at maintaining the posted speed when HUD information was available. However, when the digital HUD was used for monitoring speed, lane deviations were larger and reaction times to visual and auditory probes were longer than when either of the other two displays was present.
