This is mainly for a senior design project, but Im trying to find information about basically reading coordinates from a webcam. Namely when someone waves their hand in front of the camera, the mouse pointer will move. Simple sounding...yet hard to find info for. We had a few idea, such as using 2 cameras to read the "depth" of a persons hand moving between them. Using these components, we could then move the mouse pointer (maybe in OpenGL? with X,Y position) Another idea is something similar to Object tracking, with 1 camera. but..i can't find any libraries/info about this? Any help is greatly appreciated.
