CamShift is a tecnology developed by Intel that allows to a PC the recognition and the tracking of an object as, for example, a human face.

Nanodesktop tecnology has realized a new result: this homebrew implements the Intel tecnology under PSP

It is only a proof of concept, but in the future this could be useful for paralized humans (the tracking of the head can be analyzed by a software on PSP and it can send the commands to a system of servo mechanisms for assistance).
