Abstract

Safe interaction with interactive systems in the car requires both hands to be placed on the steering wheel and eyes to be kept on the road. To allow safe text input in the vehicle, we propose the back of the steering wheel as space for interactive text input elements. In the effort to explore this space, we present two design alternatives for text input elements; one has two sliding sensors and the other has three buttons on each side of the wheel. In combination with a head up display and an adapted keyboard layout, these elements allow text input while driving with the eyes on the road an the hands on the wheel. In a first study with end users, we show the potential of the proposed text input approach for future vehicles.
