The way it works is that an eye-gaze camera tracks the person’s eye movements, which then moves the mouse on a computer screen. The person selects items either by holding their eye-gaze for a certain time, referred to as ‘dwell’, by blinking, or by clicking an external button.
How do you evaluate eye tracking?
Gaze points constitute the basic unit of measure – one gaze point equals one raw sample captured by the eye tracker. The math is easy: If the eye tracker measures 60 times a second, then each gaze point represents a sixtieth of a second (or 16.67 milliseconds).
