A tactile interaction concept for in-car passenger infotainment systems.

Many modern cars offer in-vehicle infotainment systems to enable information and entertainment features. Often, these systems use touchscreen-based interaction concepts, which can be tedious (holding the arm) and imprecise due to the mobile context. In addition, most systems are driver-targeted and neglect the interaction by passengers. In this paper, we therefore investigate the use of an absolute indirect touch interaction concept with tactile feedback to enable passenger interaction with an infotainment system with the goal to ease screen navigation and improve user experience. Results from an experiment (N=18) reveal that this approach performs well regarding usability and user experience for both entertainment and infotainment functions.
