Eye-tracking

ramme|<ref>LC Technologies (2015)</ref>|Example on Eye-Tracking glasses "Eye tracking" is the measurement of the eye's activity. Where do we focus? What do we ignore? When do we blink? How do participants react to various stimuli? Eye tracking data is collected using either an external tool, or some kind of spectacles ("Eye tracker") which is connected to a computer. They usually consist of two components, a light source and a camera, which is directed towards the eye. The camera tracks the reflection from the light source on for example the pupil. This information is used to derive rotation of the eye and thereby the direction of the gaze. Additional information such as blink frequency and changes to the pupil diameter can also be detected by the eye tracker. The collected data is written to a file that is compatible with Eye-tracking analysis programs. <ref>Eye Tracking Inc, (2015), The process of eye tracking.
