                         rich in information about the wearers location, interactions and 
                         intentions. In the wearable domain, hand gesture recognition is 
                         the natural replacement for keyboard input. We describe a 
                         framework combining a coarse-to-fine method for shape detection 
                         and a 3D tracking method that can identify pointing gestures and 
                         estimate their direction. The low computational complexity of both 
                         methods allows a real-time implementation that is applied to 
                         estimate the users focus of attention and to control fast 
                         redirections of gaze of a wearable active camera. Experiments have 
                         demonstrated a level of robustness of this system in long and 
                         noisy image sequences.",
