Eye tracking device Scientists track eye movements in glaucoma patients to check vision impairment while driving.. Eye tracking is the process of measuring either the point of gaze (where one is looking) or the motion of an eye relative to the head.
Within computer technology, the gaze-contingency paradigm is a general term for techniques allowing a computer screen display to change in function depending on where the viewer is looking. Gaze-contingent techniques are part of the eye movement field of study in psychology.
The Eye Tribe [1] was a Danish startup company that produced eye tracking technology and was selling it to software developers for them to incorporate the eye tracking device into their applications and programs. The Eye Tribe's software allowed a user to direct a smart phone, tablet, or computer with just the look of an eye.
The Software Usability Research Laboratory at Wichita State University did a subsequent study in 2007 testing eye gaze patterns while searching versus browsing a website, and the results confirmed that users appeared to follow Nielsen's ‘F’ pattern while browsing and searching through text-based pages.

Egocentric vision or first-person vision is a sub-field of computer vision that entails analyzing images and videos captured by a wearable camera, which is typically worn on the head or on the chest and naturally approximates the visual field of the camera wearer. Consequently, visual data capture the part of the scene on which the user focuses ...
Eye tracking – Eye trackers measure the point of gaze, allowing a computer to sense where the user is looking. This information is useful in a variety of contexts such as user interface navigation: By sensing the user's gaze, a computer can change the information displayed on a screen, bring added details to attention, etc.
Eye contact signals intent of communication and the social significance of eye gaze engages theory of mind computations. [13] Because there is an overlap of activation in structures involved in theory of mind computation with regions associated with eye contact detection, this model proposes that this is the mechanism that causes the eye ...
A number of computer and smartphone applications adjust the computer video color temperature, reducing the amount of blue light emitted by the screen, particularly at night. Dry eye is a symptom that is targeted in the therapy of CVS. The use of over-the-counter artificial-tear solutions can reduce the effects of dry eye in CVS.
