Visual cues supporting direct touch gesture interaction with in-vehicle information systems

Recent in-vehicle information systems are increasingly equipped with touch screens. While classic (i.e. point-based) direct touch interaction has known benefits in non-automotive environments, it primarily relies on visual attention, which makes it a bad candidate for interaction in the car, where visual attention should be on the road. We have designed an interaction scheme for IVIS based on touch gestures and pie menus and implemented several versions of it featuring visual cues as improvements to the original idea. In an extensive user study with a primary driving task, we were able to show that our interaction scheme is significantly faster than classic touch interaction and that it demands shorter gesture using visual cues.
