Augmented Reality information on Head-Up display (AR-HUD) in a car can be relevant for visual aid and for strengthening the safety of the driver. However, some display Parameters are necessary to guarantee the good perception of these information and the driving environment. In this study, we are interested on head motion parallax, and specifically the ones generated with lateral head movements of the driver. In fact, during natural observation this cue physiologically strengthens depth perception and its absence may impact driver perception. Our goal is to demonstrate the impact of the generated movements and the projection distance on driver’s perception, using an AR-HUD. This was investigated in terms of eye-comfort and driver preferences. In this article, we focus on the primary driving task with basic lane marking highlight, and we observe how the different conditions affect subject’s perception especially during curves negotiation. Results show the importance of eye-tracking when using an AR-HUD for alignment accuracy and better comfort which directly driver performance and safety.
