ögonspårare
An ögonspårare, which translates to "eye tracker" in English, is a device used to measure either the point of gaze or the motion of an eye relative to a head. The term ögonspårare is primarily used in Swedish contexts. These devices work by illuminating the eye, typically with infrared light, and then using a camera to record the reflection of this light on the cornea, known as the corneal reflection. By analyzing the position of the pupil and the corneal reflection, the system can determine where the user is looking.
Ögonspårare have a wide range of applications. In research, they are used in psychology and human-computer interaction
The accuracy and precision of ögonspårare can vary depending on the technology used and the specific application.
