Virtually There: A Comparison of Conventional Navigational Aids with HUD Alternatives compares different navigational aids including a heads up display (HUD) to conventional aids. Participants drove routes using different aids and their driving performance, speed, and ease of use ratings were measured. Results showed participants made fewer incorrect turns and rated HUD as easiest to use, but HUD use was also associated with higher speeds. While HUD showed potential to improve navigation, further research is needed to understand benefits over other aids and address potential increased speeding.
