Eye-tracking systems determine the direction of a subject's gaze using the images provided by a camera, allowing people who are severe disabled to interact with a computer by moving the cursor to gazed points on the screen. However, detecting the wish of activation ("mouse click") only from gaze information is a well known problem. We propose a system that detects and uses muscle contraction as the source for the click command. In this way, the user will use gaze to move the cursor and then muscle activity to perform a click command.
