Nouse 'use your nose as a mouse' perceptual vision technology for hands-free games and interfaces
2004
Image and Vision Computing
Due to recent increase of computer power and decrease of camera cost, it became very common to see a camera on top of a computer monitor. This paper presents the vision-based technology which allows one in such a setup to significantly enhance the perceptual power of the computer. The described techniques for tracking a face using a convex-shape nose feature as well as for face-tracking with two off-theshelf cameras allow one to track faces robustly and precisely in both 2D and 3D with low
