Looking at HMI Concepts for Highly Automated Vehicles: Permanent vs. Context-Adaptive Information Presentation

Abstract To facilitate the usage and expected benefits of higher-level automated vehicles, passengers’ distrust safety concerns should be reduced through increasing system transparency (ST) by providing driving-related information. We therefore examined effects ST on gaze behavior during driving, trust in driving evaluation different human-machine interface (HMI) concepts. In a simulator, 50 participants experienced three identical highly drives under HMI conditions: no (only conventional speedometer), context-adaptive (all information only available more complex situations) or permanent permanently available). Compared to without HMI, introduction two HMIs resulted significantly higher center stack display (i.e. gazes towards HMIs), which was accompanied ratings. The considerable differences availability provided versus did not reflect similarly regarding Additionally, user experience evaluations expressed preferences for HMI. Hence, seem create over supporting economical, vehicles.
