The Mouseless is a proposed input device for personal computers.
A prototype Mouseless, designed by Pranav Mistry of the MIT Media Lab.
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.
According to Mistry' statement, the fully functional prototype of the Mouseless costs around $20.
