15 Facts About Eye tracking

Eye tracking is the process of measuring either the point of gaze or the motion of an eye relative to the head.

Eye tracking trackers are used in research on the visual system, in psychology, in psycholinguistics, marketing, as an input device for human-computer interaction, and in product design.

Eye tracking trackers are being increasingly used for rehabilitative and assistive applications .

Eye tracking showed that the task given to a subject has a very large influence on the subject's eye movement.

Eye tracking wrote about the relation between fixations and interest:.

Therefore, eye tracking is often coupled with other methodologies, such as introspective verbal protocols.

Optical methods, particularly those based on video recording, are widely used for gaze-Eye tracking and are favored for being non-invasive and inexpensive.

Eye tracking movements are typically divided into fixations and saccades – when the eye gaze pauses in a certain position, and when it moves to another position, respectively.

People with severe motor impairment can use eye tracking for interacting with computers as it is faster than single switch scanning techniques and intuitive to operate.

Eye tracking is helpful in analysing visual search patterns, detecting presence of Nystagmus and detecting early signs of learning disability by analysing eye gaze movement during reading.

Eye tracking has already been studied for flight safety by comparing scan paths and fixation duration to evaluate the progress of pilot trainees, for estimating pilots' skills, for analyzing crew's joint attention and shared situational awareness.

Eye tracking technology was explored to interact with helmet mounted display systems and multi-functional displays in military aircraft.

Research on interacting with multi-functional displays in simulator environment showed that eye tracking can improve the response times and perceived cognitive load significantly over existing systems.

In recent time, eye tracking technology is investigated in automotive domain in both passive and active ways.

Eye tracking is used to monitor cognitive load of drivers to detect potential distraction.
