Although screen-based trackers have a limited monitoring range, they still provide enough freedom of eye movements for the respondents to remain unrestricted. These trackers require the respondent to be in front of a monitor screen to interact with content on a screen. Both are used in various research areas, but their utility and the data they collect differ. These are screen-based and glass eye trackers. While the market has several different eye-tracking devices and software, eye research principally depends on two types. The accuracy necessary may therefore be problematic to attain in short of an infrared light source. Thus, normal light sources with ordinary cameras may find it challenging to track and provide the required contrast. Infrared light sources, which are the primary detection methods, are necessary because the gaze’s accuracy depends on the pupil’s clear demarcation and the recognition of your corneal reflection. Through filtering and many calculations, the machines are then able to detect where you are looking. The process of monitoring optical reflections of the cornea is called the pupil center corneal reflection (PCCR). The reflections are the vector in which the cornea and the pupil relate and are tracked using the infrared camera. During eye-tracking, the gaze point is measured by directing an infrared-like light into the eye pupil and the entire cornea. The Basics of Eye-Tracking SoftwareĪs mentioned, eye tracking is when intelligent computerized devices are operated to measure where we look. Gaze Point has advanced eye-tracking software and equipment for comprehensive and professional eye-tracking, providing these services and softwares across the country. It’s a technology that enables people with mental and physical deformities to enjoy more prosperous and independent lives. Sometimes, it’s used as a substitute for conventional mice and keyboards. Eye tracking, also known as gaze interaction, is a technology used in research to see where someone is looking on a computer screen.
