Silmäseurantaa

Silmäseurantaa, which translates to "eye tracking" in English, is a technology that allows for the measurement and analysis of eye movements. This technology tracks the gaze, attention, and focus of a person's eyes as they look at a screen, a physical object, or their surroundings. Devices used for eye tracking range from specialized infrared cameras to integrated sensors in devices like smartphones and computers.

The fundamental principle behind most eye tracking systems involves emitting infrared light onto the user's eyes. This light is reflected by the cornea and the pupil. The eye tracker then captures these reflections, and sophisticated algorithms analyze the patterns to determine the precise point of gaze. The accuracy and speed of these systems are crucial for their effective application.

Eye tracking has a wide array of applications across various fields. In user experience research, it helps understand how people interact with websites, applications, and products, identifying areas of interest and confusion. In marketing, it can reveal what elements of advertisements capture attention. For individuals with disabilities, eye tracking technology can serve as a powerful assistive communication tool, allowing them to control devices and interact with the world through their gaze. It is also utilized in academic research, psychology, and even in the gaming industry.
