Can haptics facilitate the interaction with an in-vehicle multifunctional interface?

Validerad; 2009; 20090624 (ysko)
A driving simulator study was conducted to investigate whether the interaction with an in-vehicle multifunctional interface maneuvered by a rotary control can be improved if assisting haptics is provided. Two conditions were compared in the study, one in which neutral haptics was provided through the rotary control and one in which enhanced haptics was provided. Participants drove on a curved rural road while performing tasks such as list scrolling, radio tuning and text entry. The results indicated that, for radio tuning and settings adjustments tasks, interaction is improved when enhanced haptics is provided. It was shown that enhanced haptics can increase performance in terms of task completion time and can reduce the number and duration of glances made to the display. However, for alphanumeric input tasks, improvements are needed. Enhanced haptics seems to facilitate interaction with functions in which the sensations can be incorporated in an intuitive way.
