silmäseurantat

Silmäseuranta, often translated as eye tracking, is a technology that allows a device to determine where a person's eyes are looking. It works by detecting and measuring eye movements, fixations, and pupil dilation. This information can then be used to understand attention, cognitive load, and interaction patterns.

There are several methods used for eye tracking. Remote eye trackers are typically mounted below a screen and use infrared light and cameras to capture reflections from the cornea and pupil. Head-mounted eye trackers are worn by the user, often as part of a headset or glasses, and offer greater accuracy and freedom of movement. They also use cameras and illuminators to track the eyes.

The applications of silmäseuranta are diverse. In research, it's used in fields like psychology, human-computer interaction, and marketing to study visual attention and user experience. It plays a crucial role in usability testing, helping designers identify areas of confusion or interest on interfaces. For individuals with disabilities, eye tracking technology can serve as an alternative input method for computers and communication devices, enabling control through eye movements. It is also employed in areas such as driver monitoring systems to detect drowsiness and in sports to analyze athlete performance. The data generated by eye tracking can provide insights into subconscious responses and decision-making processes.
