Øjensporing

Øjensporing, also known as eye tracking, is a technology that records and analyzes the movement of an individual's eyes. It is used in various fields, including psychology, neuroscience, marketing, and human-computer interaction. Eye tracking systems typically use either video-based or electro-ocular graphic (EOG) methods to detect eye movements.

Video-based systems use cameras to capture the movement of the eye and the surrounding area. These systems can be further categorized into remote and head-mounted types. Remote systems are non-intrusive and allow for natural movement, while head-mounted systems provide higher accuracy but may restrict movement. EOG systems, on the other hand, use electrodes placed around the eye to detect electrical signals generated by eye movements.

Eye tracking data can provide valuable insights into cognitive processes, such as attention, perception, and decision-making. In marketing, it is used to understand consumer behavior and preferences. In human-computer interaction, it helps improve user interfaces by optimizing the placement of elements based on where users look.

The accuracy and reliability of eye tracking systems have improved significantly over the years, making them a valuable tool in various research and application domains. However, ethical considerations and privacy concerns must be addressed when using eye tracking technology.
