Integrated HMI Concept for Driver Assistance and Automation

Abstract

The present study describes the development of an integrated ADAS HMI concept within the European-funded research project interactIVe, its implementation and user-centred validation in a driving simulator. The HMI concept integrated visual, haptic and acoustic information-, warning- and intervention (IWI) strategies, and allowed the driver to select between three different assistance and automation levels. The concept was implemented in the fully interactive Ford HMI driving simulator and was validated in an empirical user study with N=24 participants. The vast majority of the sample was positive about the idea of integrated assistance functions integrated in three selectable modes. Good comprehensibility and learnability of the mode selection concept could be proven. The visual display concept with safety zone segments around the vehicle - representing the safety-shield metaphor - was positively recognized. User feedback and observation results also revealed some weaknesses in system usability. Detailed suggestions for improvement could be derived.
