Abstract
We developed a system of free-hand pointer by tracking the finger of the speaker with an active stereo vision system and then computing the projection direction in either of the following two modes: the finger-orientation mode and the eye-to-fingertip mode. We prefer the latter for its robustness. In order to allow the speaker to move around in a wider 3D space without reducing the pointing resolution, we utilize a well-calibrated active stereo vision system which has a relatively small field of view but can control its stereo cameras to fixate at the moving finger. Our experiments have successfully demonstrated the feasibility of developing a free-handpointer using an active stereo vision system.
