Everybody knows presentations driven by small wireless control devices, pushing a button and slides go forward or backwards. My friends at stereolize always look for a more performance based interface and therefore we setup an interface which requires active body movement and visible interaction with the projection.

A slider was tided to the presenters position, automatically selecting options at the screen. In addition, big buttons at the screen could be pressed to move forward in the presentation or start specific content such as movies. you can imagine that initially some presenters had concerns regarding the stability of this interface but we convinced everybody within seconds. there was not one glitch throughout the whole cebit and we are sure to keep developing this idea futher.
