Tips and Tricks when using Eyetracker.
An eye tracker is used to record eye movements relative to the head or the direction of gaze. It is an established method in e.g., psychology, neurology, engineering, and human factors.
The majority of modern eye trackers are video based, which means that they measure eye movements by tracking the position of the pupil and one or several corneal reflections in each frame of the video. The recorded data typically consist of the gaze position (x,y) on the stimulus and the size of the pupil, acquired at sampling rates between 50 and 1000 Hz.
MULTILING has one eye tracker, the SMI RED 250 mobile.
