Nouse ‘Use Your Nose as a Mouse’ – a New Technology for Hands-free Games and Interfaces
Dmitry O. Gorodnichy · 2002
With the invention of fast USB interfaces and recent increase of computer power and decrease of camera cost, it has become very common to see a camera on top of a computer monitor. Vision-based games and interfaces however are still not common, even despite the realization of the benefits vision could bring: hand-free control, multiple-user interaction etc. The reason for this lies in the inability to track human faces in video both precisely and robustly. This paper describes a face tracking technique based on tracking a convex-shape nose feature which resolves this problem. The technique has been successfully applied to interactive computer games and perceptual user interfaces. These results are presented.
