High Quality Content by WIKIPEDIA articles! The Mouseless is a proposed input device for personal computers. A prototype Mouseless, designed by Pranav Mistry of the MIT Media Lab, replaces conventional hardware mouse with a set of infrared laser strobe, an infrared camera and image recognition software. The laser beam is optically split into a wide beam illuminating an imaginary plane above the working desk. The camera captures the pattern of invisible infrared light as it illuminates user`s hand. The user rests the palm on the desk and commands the system in the same way as he or she would do with a conventional mouse.
