Silmajuhtimine

Silmajuhtimine, also known as eye tracking, is a technology that allows devices to detect a person's gaze and determine where they are looking. This is achieved through the use of infrared light and cameras. An infrared light source illuminates the user's eye, and a camera captures images of the eye. Specialized software then analyzes these images to pinpoint the location of the pupil and cornea, and by measuring the reflection of the infrared light on the cornea (a glint), it can calculate the direction of gaze.

The applications of silmajuhtimine are diverse. In accessibility, it provides a crucial alternative input method for individuals with severe motor impairments, enabling them to control computers, communicate, and interact with their environment using only their eyes. This can involve selecting letters on a virtual keyboard, navigating menus, or even playing games. In research, eye tracking is used in fields like psychology and human-computer interaction to understand attention, cognitive load, and user experience. For instance, researchers might study where users look on a webpage to assess its effectiveness or how people process visual information.

Furthermore, silmajuhtimine finds use in market research and advertising to analyze consumer behavior, such as observing what product packaging or advertisements attract the most attention. It is also employed in fields like driver monitoring systems to detect drowsiness or distraction by tracking eye closure and gaze patterns. The technology continues to evolve, becoming more accurate, affordable, and integrated into various devices.
