Demo of a tremor compensation system using electrical stimulation. Based on information from portable sensors, the controller applies higher currents for stronger tremors. Tremor is induced with an auxiliary stimulator.

This video by Carlos Gonçalves demonstrates the operation of a virtual keyboard using a regular webcam and readings of the user's head movement. The idea is to design an input system for people with impairments that cannot use conventional mouse or keyboard. Following developments include more robust techniques to detect command gestures.
