A Design Science Study on Methods of Feedback for In-car Gesture-controlled Infotainment Systems

Abstract: Navigating an in-car infotainment system by using gesture-control can be distracting, drivers usually seek for confirmation from the infotainment system by rapidly glancing at the screen and therefore reduce the eyes-on-the-road time, this can be dangerous. This study aims to evaluate whether if by applying both visual and auditory feedback from the infotainment system can reduce the distraction. One iteration of design science is performed with results showing that by applying the combination of audio (different clicking sounds) and colour (different colour changes) feedback, the distraction is reduced according to the qualitative interview results, participants claimed that they can use the system without looking at the screen. Suggestions are also made to improve the system by adding feedback methods such as voice assistant, or different audio cues, can be applied and have the potential to reduce the distraction even further. Although the study could not distinguish between whether if the result is led by the user interests to
