Today’s automobiles serve not only as vehicles but also as mobile offices combining communication tools such as cellphones and car navigation systems providing online information services. The many switches are conventionally distributed on the dashboard. A move is under way, however, to combine them into a multifunctional touch panel. We propose a voice-supported active touch panel. Since information feedback to the operator is important in ensuring correct function selection, the panel we designed combines a vibrator and voice explanation. Touch sensors use PZT thin film sensors. The voice explanation uses a quick response system. This paper reports the features and configuration of the voice-supported active touch panel.
