My research focuses on the development of novel techniques for the visual and audio-visual perception of humans and their activities, in order to build perceptive human-friendly systems.
I am particularly interested in building complete human-friendly systems, such as human-friendly robots, smart environment and assistive technology for people with visual impairments. I'm also interested in automatic analysis of multimedia content and video surveillance applications.
My team and I have been working on a number of perception components including person tracking, person identification, recognition of pointing gestures, estimation of head orientation and focus of attention, as well as audio-visual scene and activity analysis.
In addition to my research group on "Computer Vision for Human-Computer Interaction (CV-HCI)" at the Karlsruhe Institute for Technology (formerly Universität Karlsruhe (TH)), I'm head of the KIT's Study Center for Visually Impaired Students (SZS)".
I also closely collaborate with the Perceptual User Interfaces research group at the Fraunhofer Institute for Optronics, System Technologies and Image Exploitation - IOSB in Karlsruhe.
I'm co-founder of Videmo Intelligente Videoanalyse GmbH Co. KG. Videmo develops innovative software and algorithms for automatic video analysis in a wide range of application areas such as security, customer analysis, traffic monitoring and health care.
- Please see the list of ongoing projects on my research groups' homepage
- I was member of the Franco-German project Quaero. Here, we contributed to video-based and multimodal multimedia analysis, in particular the detection and recognition of people, events and genres in images and videos.
- In 2007, I was awarded an Attract project funded by the Fraunhofer Gesellschaft. It was called "Visual perception of people - interaction in and with attentive rooms". Work on this project was conducted with my research group at the Fraunhofer Institute for Optronics, System Technologies and Image Exploitation - IOSB in Karlsruhe
- I was member of the German Research Center on Humanoid Robots (SFB 588) In this project we contributed the key components for the visual perception of people and their activities to the Karlsruhe humanoid robot.
- I was member of the coordination team of CHIL - Computers in the Human Interaction Loop. Here, we have extensively worked on audio-visual perception of people in and for smart environments.
