ABSTRACT="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, that it demands less visual attention (as
confirmed by improved driving performance) and that our improvements
further increased these effects."
