eye tracker

A simple calibration procedure of the individual is usually needed before using the eye tracker.

The most widely used current designs are video-based eye trackers.

Evidently there was an eye tracker operating somewhere.

Eye trackers necessarily measure the rotation of the eye with respect to the measuring system.

The second technique is an eye tracker.

Most of times an eye tracker is not part of a standard lab and it is still expensive.

An eye tracker is a device for measuring eye positions and eye movement.

Edmund Huey built an early eye tracker, using a sort of contact lens with a hole for the pupil.

(1973) Accurate two-dimensional eye tracker using first and fourth Purkinje images.

The first and fourth Purkinje images are used by some eye trackers, devices to measure the position of an eye.

Eye trackers which precisely measure the eye's position and movement are also commonly used to determine fixation points in perception experiments.

Eye tracking - Eye trackers measure the point of gaze, allowing a computer to sense where the user is looking.

The results were compared with parallel sessions in which people used an onscreen keyboard and eye tracker to take dictation.

When the display is manipulated with the use of an eye tracker, this is known as a gaze contingent display.

Examples of trackers include motion trackers, eye trackers, and data gloves.

Video based eye trackers typically use the corneal reflection (the first Purkinje image) and the center of the pupil as features to track over time.

It is important to realize that the eye tracker does not provide absolute gaze direction, but rather can only measure changes in gaze direction.

Eye trackers are used in research on the visual system, in psychology, in cognitive linguistics and in product design.

Eye trackers bounce near infra-red light off the interior of the eyeball, and monitor the reflection on the eye to determine gaze location.

Eye trackers can also be used to detect eye movements so that the system can determine precisely where a user is looking at any given instant.

EyeGuide was developed as an affordable alternative to other eye trackers for the Texas Tech University's usability lab.

They used a special "eye tracker" camera to follow Mr. Ocean's eye movements and a sensor that recorded his hand movements.

The eye tracker used in the experiment was manufactured by EyeTech Digital Systems of Mesa, Ariz.

In general, commercial eye tracking studies function by presenting a target stimulus to a sample of consumers while an eye tracker is used to record the activity of the eye.

The company produces the EyeGuide Eye Tracker system, which was released in October, 2011, and EyeGuide Assist, a mouse replacement tool.
