In Linz the students of the course unconventional user interfaces showed their first set of functional prototypes. The topics are related to interactive mirrors, context-aware advertisement posters, healthy rear-seat entertainment, and text input while driving. The assignment was to create a system that allows creating an authentic user experience for the concept. The technical solutions were very different and ranged from a dismantled keyboard to a system using a micro-controller, from a two-way mirror with display behind to direction detection in front of an advert. Even though the prototypes were fairly simple most of them showed impressively how much of an idea a functional prototype can transport.
