Biography
David Przewozny is computer vision developer. His research is focused on humans in front of the camera. Using different types of cameras, e.g. low cost, high speed or depth cameras, he demonstrated how to preserve privacy while sharing presence information, tracking eyes for 3D displays or analyze the gait of older persons.
However analyzing the hands of the user in front of the machine (computer) is his main research focus. Currently he develops a multi-modal interaction system for intensive care units. Mouse, touch, proximity, hand postures, hand gestures, head gestures as well as speech recognition are combined to support care givers in using the medical devices faster and easier than before.
Together with Rene de la Barre and Siegmund Pastoor he received the Josef Fraunhofer Award in 2006.
David Przewozny received the Dipl.-Ing. in computer science from Technical University of Berlin in 1999.
