In this paper we present a real-time 3D object tracking algorithm based on edges and using a single pre-calibrated camera. During the tracking process, the algorithm is continuously projecting the 3D model to the current frame by using the pose estimated in the previous frame. Once projected, some control points are generated along the visible edges of the object. The next pose is estimated by minimizing...
INTOI is a rear-projection setup which combines accurate pen tracking with hand gesture recognition. The hardware consists of an Anoto pattern printed on a special rear-projection foil and an infrared tracking system. INTOI is a low-cost system that is scalable and provides highly accurate input (to less than 1mm). Finally, our setup supports a novel multi-user interaction that combines simultaneous...
