øjenbevægelsesanalyse

Eye movement analysis, or øjenbevægelsesanalyse in Danish, is a research field and a diagnostic tool that studies the patterns and characteristics of human eye movements. It involves recording and analyzing how the eyes move during various tasks, such as reading, visual search, or visual tracking. This analysis can provide insights into cognitive processes, attention, and visual perception.

The technology used for eye movement analysis typically involves an eye tracker, which can be mounted on a computer screen or a head-mounted device. These trackers use infrared light to monitor the position of the pupil and corneal reflection, allowing for precise measurement of gaze direction. Data collected includes fixation points (where the eye pauses), saccades (rapid, ballistic movements between fixations), and pupil dilation, which can be an indicator of cognitive effort.

Applications of eye movement analysis are diverse. In usability research, it helps understand how users interact with websites and software, identifying areas of interest or confusion. In psychology and neuroscience, it is used to study attention, memory, and the underlying neural mechanisms of vision and cognition. In clinical settings, it can aid in the diagnosis of neurological disorders, learning disabilities like dyslexia, and developmental conditions such as ADHD, by identifying abnormal eye movement patterns.

The interpretation of eye movement data requires specialized software and expertise. Researchers and clinicians analyze metrics like scan paths, fixation durations, and dwell times to draw conclusions about an individual's visual behavior and cognitive state. The field continues to evolve with advancements in tracking technology and analytical techniques.
