Audio-Haptic Car Navigation Interface with Rhythmic Tactons

While car environment is often noisy and driving requires visual attention, still navigation instructions are given with audio and visual feedbacks. By using rhythmic tactons together with audio, navigation task could be supported better in the driving context. In this paper we describe haptic-audio interface with simple two-actuator setup on the wheel using rhythmic tactons for supporting navigation in the car environment. The users who tested the interface with a driving game would choose audio-haptic interface over audio only interface for a real navigation task.
