silmätallennus

Silmätallennus, also known as eye tracking, is a technology that measures the point of focus or motion of a person's eye relative to their head. This is typically done using specialized equipment that tracks the pupil's position. Eye tracking systems can be used to record where a person is looking, how long they are looking at a particular spot, and the path their gaze takes across a screen or scene.

The primary applications of eye tracking are in research and usability testing. Researchers use it to understand visual attention in fields like psychology, marketing, and human-computer interaction. For example, it can reveal what elements of a website or advertisement attract the most attention, or how users navigate complex interfaces. In clinical settings, eye tracking can aid in the diagnosis and monitoring of certain neurological conditions or vision impairments.

There are various methods for eye tracking, including remote eye trackers that do not require the user to wear any equipment and screen-based systems where the tracker is integrated into a monitor. Mobile eye trackers are also available for use with portable devices. The data generated by eye tracking can be visualized in various ways, such as gaze plots, heatmaps, and scan paths, to provide insights into visual behavior. The technology has also found applications in assistive technology, enabling individuals with severe motor impairments to control devices with their eyes.
