Is eye tracking bad for eyes?

Tobii Eye Tracking devices are using near-infrared illumination to create reflections on the eyes that can be tracked with high accuracy. Light emission that meets this standard is not harmful to the human eye.

What do you need for eye tracking?

An infrared light source (and thus detection method) is necessary as the accuracy of gaze direction measurement is dependent on a clear demarcation (and detection) of the pupil as well as the detection of corneal reflection.

What type of measure is eye tracking?

When we talk about eye tracking, fixations and gaze points are the basic output measures of interest and often the most used terms. Gaze points show what the eyes are looking at. If your eye tracker collects data with a sampling rate of 60 Hz, you will end up with 60 individual gaze points per second.

What is eye tracking in psychology?

What is an eye tracking problem?

With tracking problems, eye movements are slow, inaccurate, or require head or finger movement to help the eyes track. This can interfere with reading fluency and comprehension, copying, handwriting, and sports performance.

How do you do eye tracking?

The basic concept is to use a light source to illuminate the eye causing highly visible reflections, and a camera to capture an image of the eye showing these reflections. The image captured by the camera is then used to identify the reflection of the light source on the cornea (glint) and in the pupil.

Why do babies stare into your eyes?
