Dorsal Haptic Display is an automotive interface questioning how we perceive a car’s surroundings. Motors in a car seats backrest stimulate the driver’s back with a projection of rear obstacles. We conducted a first user study to prove basic functionality and presented our results at AutomotiveUI 2015 in Nottingham, UK, in September.

After some improvements in latency and rendering of the “haptic image” the system was demonstrated at this years International Conference on Persuasive Technology and for a broader public during “Lange Nacht der Forschung”.
