56‐3: Perceptual and Safety Aspects of Augmented Reality Head‐Up Displays in Cars

This study aimed to design visual information for a navigation feature in an Augmented Reality (AR) Head‐Up Display (HUD) and integrate the graphics into a Volvo XC60 concept car. The implemented graphics were then tested with users driving the vehicle on public roads. The results were analyzed to determine whether AR‐HUD could enhance perception, attention, and safety. User evaluations revealed that AR‐HUD helped drivers keep their eyes on the road more frequently when using AR guidance compared to a conventional HUD. Both qualitative and quantitative data indicated that presenting clear and well‐timed information for an optimal duration was the key factor in designing human‐machine interfaces that support effective user interactions.
