| Abstract In-vehicle ambient lighting offers potential as an implicit interface for supporting driver attention, yet its effectiveness in this application is unclear. This exploratory driving simulator study investigated how visual attention feedback using ambient lighting was perceived by drivers. Twelve drivers completed a car-following task while engaging in a forced visual distraction task under three ambient lighting conditions: discrete flashing, temporal change and colour change. Post-drive interviews guided by the Critical Decision Method examined their perception, comprehension and projection of the different states. While most drivers noticed the lighting, few correctly interpreted it as attention feedback, and no consistent reduction in visual distraction was observed. Findings suggest that ambient lighting alone is insufficient to reallocate driver attention without clearer meaning and behavioural alignment. |
