RoundTable a physical input device for the control of virtual cameras. The so called round table has a round projection area as well as a personal workspace for each user. Using physical icons (phicons) the user can stipulate the position of virtual cameras. The resulting scene is displayed on a projection screen. With this scenario we propose a hybrid mixed reality environment for real-time camera control during a live-broadcast. Another application of the RoundTable deals with a artistic real-time sound-mixing application.
	Group Interaction people experience the sense of presence in a virtual space through movements as much as through visual or acoustic impressions. As social beings people are necessarily aware of their (local) position in group situations and they experience the physical space and the social climate of a group situation by simultaneously watching and moving around. In two projects we explore the modalities and limitations of group interaction in mixed-reality scenarios.
	Intuitive Interface An environment which allows for a more intuitive man-machine communication by using the entire space in front of a large rear-projection screen. Computer vision, recognizing movements, gestures and posture, and speech recognition are used, placing the user in a non-intrusive environment. The interaction is related to the location and movement of the user withing this space. The interface has a special focus on the needs of people in creative fields such as visual arts or film (abstract).
	Interactive Film Planning System A system for creating and modifying typical situations for planning films by using multimodal interaction combining speech and gesture recognition. This ongoing research project involves several computer scientists and media designers. The research I undertake focuses on gesture recognition. The Film Planning System is one application of the Intuitive Interface (see Intuitive Interface for more info).
	Facial Animation In my master thesis for computer science diploma about model based facial animation I used laser scanner data and B-splines to automatically generate facial masks that could be animated without further fine tuning (abstract).
	Facial Animation During my Internship at Apple Computer, in Cupertino, I implemented a pratical solution for tracking edges in image sequences using snakes with a special application to facial animation (abstract).
