øjentracking
Eyetracking is a method used to measure eye movements or the path of the eye relative to the head. It records the position of the eye and can determine where a person is looking, how long they are looking at a particular spot, and the sequence of their gaze points. This is typically done using specialized devices called eyetrackers. These devices can range from head-mounted systems to screen-based units that use infrared light to reflect off the cornea and pupil. The reflected light patterns are then analyzed by a camera to calculate the gaze direction.
The data generated by eyetracking can be visualized in various ways, such as heatmaps, which show areas
