Flashing signal lamps and unfamiliar control elements tend to worry car drivers. The Avatar-based Virtual Co-driver System (AviCoS) will provide drivers with information directly and on-demand, making cumbersome paging through owner’s manuals a thing of the past. The AviCoS system reacts to a touch of the control elements and via a natural-language interface. A virtual assistant, the avatar, dispenses explicit information on the vehicle – supported by images and videos. The system was developed by the Technische Universitaet Muenchen Institute of Business Informatics in cooperation with Audi AG.
