The head-up-display (HUD), which reflects driving information into the windshield has the goal to lower driving effort from the information uptake and thereby, increase our safety by reducing risks associated to e.g., fatigue and stress. However, the user acceptance of the Advanced Driving Assistance Systems (ADAS) is remarkably low. This motivated us to test the HUD by conducting a real-world experiment with 48 subjects who drove in real traffic conditions two premium vehicles in a highway in Germany. After each ride, participants rated their driving experience in terms of Human-Machine Interface (HMI), their feelings of safety and driving effort. Results from CMP regressions (Roodman, Stata J.
11, 159–206 (
2011)) show that the HUD has a significant positive effect on the driving effort and safety feelings, and on the overall driving experience. Moreover, we find that this effect is stronger among risk-averse drivers, elderly, students, and females. In particular, women felt significantly safer while the HUD was activated. To reverse low ADAS acceptance, specific differentiation settings regarding the driver’s profile are discussed.
