A multimodal perceptual user interface for video-surveillance environments

In this paper a perceptual user interface (PUI) for video-surveillance environments is introduced. This system provides a tool for a video-surveillance control-room, and exploits a novel multimodal user interaction paradigm based on hand gesture and perceptual user interfaces. The proposed system, being simple and intuitive, is expected to be useful in the control of large and dynamic environments. To illustrate our work, we introduce a proof-of concept multimodal, bare-hand gesture-based application and discuss its implementation and the obtained experimental results.
