Testing external HMI designs for automated vehicles – An overview on user study results from the EU project interACT

Kurzfassung

This paper gives an overview on the design and research work conducted in the EU interACT project. The objective of the project is to ensure the safe integration of Automated Vehicles (AVs) into mixed traffic environments. Based on psychological models of current interaction between humans in traffic, interaction design strategies were defined for the implicit and explicit communication of an AV with other road users. Those strategies were tested with users in eight simulator studies. The main objectives, methods and results of these studies are summarized in this paper. The outcomes of the studies reveal a need for a welladjusted communication of the AV by implicit and explicit (external HMI) signals in urban environments.
