The eye tracker sends out near infrared light. The light is reflected in your eyes. Those reflections are picked up by the eye tracker’s cameras. Through filtering and calculations, the eye tracker knows where you are looking.

How does the eye tracker Challenge work?
The eye tracking technology is based on pupil center corneal reflection (or PCCR). This means that an infrared light source illuminates your eyes. An image sensor can then detect the reflection. Add some calibration and algorithm magic, and what you get back is the gaze bubble on your screen.
Is eye tracking accurate?
The (spatial) quality of the tracked gaze can be measured in terms of precision and accuracy.Accuracy is often reported by manufacturers to be < 0.5°. However, in particular for remote eye trackers, offset from the true gaze point is often found to be larger than 1° [5, 30], even in controlled environments.

20-40 ms
the average duration of a saccade is 20-40 ms. the duration of a saccade and its amplitude are linearly correlated, i.e. larger jumps produce longer durations. the end point of a saccade cannot be changed when the eye is moving.
What is the precision of eye?
Precision is defined as the ability of the eye tracker to reliably reproduce the same gaze point measurement, i.e. it measures the variation of the recorded data via the Root Mean Square (RMS) of successive samples.
Can you use a webcam for eye tracking?
Webcam Eye Tracking is detecting an individual’s gaze location using a webcam rather than a real eye tracker with infrared illuminators.They can do it remotely behind their screens only with a webcam and good internet connection.

Are humans blind 40 minutes a day?
Humans are blind for about 40 minutes per day because of Saccadic masking—the body’s way of reducing motion blur as objects and eyes move. 20/20 isn’t perfect vision, it’s actually normal vision—it means you can see what an average person sees from 20 feet.
What triggers a saccade?
On average, for T(XE) between 40 and 180 ms, no saccade is triggered and target tracking remains purely smooth. Conversely, when T(XE) becomes smaller than 40 ms or larger than 180 ms, a saccade is triggered after a short latency (around 125 ms).
