Touchlib - Home. Touchlib is a library for creating multi-touch interaction surfaces.
It handles tracking blobs of infrared light, and sends your programs these multi-touch events, such as 'finger down', 'finger moved', and 'finger released'. It includes a configuration app and a few demos to get you started, and will interace with most types of webcams and video capture devices. It currently works only under Windows but efforts are being made to port it to other platforms. Who Should Use Touchlib? Touchlib only comes with simple demo applications.
