A less than 15 second calibration procedure is required to set up the system for a particular user.
The user looks at a small calibration point as it moves around the screen.
There is no need to recalibrate if the user moves away from the screen and returns later.
A user operates the system by looking at rectangular “keys” or cells that are displayed on the control screen. To “press” a key, the user looks at the key for a specified period of time.
The gaze duration required to visually activate a key, typically about ½ second, can be adjusted by the user.
An array of menu keys and exit keys allow the user to navigate the Eyegaze programs independently.
