Fixációhossz

Fixációhossz, often translated as fixation duration or fixation length, refers to the amount of time a person's gaze remains relatively stationary on a specific point in their visual field. This stationary period is known as a fixation. When we look at something, our eyes do not move in a continuous, smooth fashion. Instead, they make a series of rapid, jerky movements called saccades, which shift our gaze from one point to another. In between these saccades, the eyes pause for a brief period, and this pause is a fixation.

The duration of a fixation can vary significantly depending on factors such as the complexity of the visual scene, the task being performed, and individual cognitive processes. For example, when reading, fixations tend to be shorter on common words and longer on less familiar or longer words. In visual search tasks, fixations might be prolonged on areas of interest or where a target is suspected. The average fixation duration in adults is typically around 200-250 milliseconds, but this can fluctuate. Analyzing fixation duration is a common method in eye-tracking research to understand attention, cognitive load, and information processing during visual tasks. Shorter fixations might indicate rapid processing or a lack of deep engagement, while longer fixations can suggest more effortful processing, deeper comprehension, or a greater level of interest.
