Abstract:
Automated vehicles will likely use some form of external Human Machine Interfaces in the future to communicate with other road users. Using projections, the communicated message can be addressed and directed towards certain traffic participants. The present study evaluated the effects of projection-based eHMI on the road user behaviour using a unity based pedestrian simulator. Results reveal that while green signalling lights are preferred over the colours cyan and magenta, the colour green is mostly interpreted as a movement prompt. In ambiguous situations undirected signalling confused study participants showing that pedestrians refer signals of vehicles in their vicinity to themselves. Therefore, undirected signalling should only be used when no one else standing around the vehicle could also see it. Otherwise, it is safer to not communicate at all. While study participants overall preferred projections in front of the vehicle using a crosswalk symbol and moving arrows, different eHMIs had marginal effects on the time, the participants needed to enter the encroachment zone.
