Natural Visual User Interfaces Beyond Input Modalities

The understanding of Natural User Interfaces (NUIs) commonly refers to user input which is often realized through speech or gesture interaction. However, car manufacturers have not yet extensively integrated natural input into their products. In our opinion, the feedback channel back to the driver as well as natural output modalities have been neglected in the discussions of NUIs. Visual presentations that integrate strategies of human visual perception can possibly serve as an appropriate output channel, enrich speech and gesture interaction with feedback and in turn increase user acceptance. We propose the integration of stereoscopic or large display solutions for the development of NUI concepts. Our approach allows for a seamless integration of displays into the vehicles environment and interior so that the borders between virtual and physical space become indistinct. In this paper, we discuss potentials and limitations of Natural Visual User Interfaces (NVUIs) in an automotive context. We provide first steps towards assessing the design space of visual output for NUIs to inspire future research.
