øjenbevægelsesstyring

Eye-tracking, or øjenbevægelsesstyring in Danish, is a technology that allows a computer or device to understand where a person is looking. It works by tracking the movement of the eyes, typically using infrared light and cameras. The system records the path of the gaze, noting the fixation points (where the eyes stop) and saccades (rapid movements between points). This data can then be used to control devices or provide information about a user's visual attention.

The primary applications of eye-tracking are in assistive technology for individuals with severe physical disabilities who may have difficulty using traditional input methods like keyboards or mice. By looking at specific icons or areas on a screen, users can interact with their computer, send messages, or operate other connected devices. Beyond accessibility, eye-tracking is employed in research for understanding user behavior in areas like marketing, web design, and human-computer interaction. It can reveal what elements attract attention and how people process visual information. Further uses include usability testing of interfaces, gaming, and in some medical and psychological studies. The accuracy and speed of eye-tracking systems have improved significantly, making them a versatile tool for various applications.
