  2. Eye tracking - Wikipedia

    en.wikipedia.org/wiki/Eye_tracking

    Specifically, eye-tracking can be used to assess search efficiency, branding, online advertisements, navigation usability, overall design and many other site components. Analyses may target a prototype or competitor site in addition to the main client site. Eye-tracking is commonly used in a variety of different advertising media.

  3. Visual processing abnormalities in schizophrenia - Wikipedia

    en.wikipedia.org/wiki/Visual_processing...

    Eye movements are important behaviors for locating and tracking objects in the visual world. Two of the major types of eye movements are saccades and smooth pursuit. Saccades are very rapid and precise eye movements between two positions, and are important in establishing fixation. Smooth pursuit on the other hand, allows the viewer to track a ...

  4. Vergence-accommodation conflict - Wikipedia

    en.wikipedia.org/wiki/Vergence-accommodation...

    The technique requires an eye-tracking solution and means of modulating focal distance of a screen. Modulation of a focal distance can be, for example, physical actuation of the screen in relation to a fixed eyepiece optics, alternatively it can be utilization of varifocal [ 23 ] [ 24 ] lens element(s).

  5. Convergence insufficiency - Wikipedia

    en.wikipedia.org/wiki/Convergence_insufficiency

    The symptoms and signs associated with convergence insufficiency are related to prolonged, visually demanding, near-centered tasks. They may include, but are not limited to, diplopia (double vision), asthenopia (eye strain), transient blurred vision, difficulty sustaining near-visual function, abnormal fatigue, headache, and abnormal postural adaptation, among others.

  6. Video-oculography - Wikipedia

    en.wikipedia.org/wiki/Video-oculography

    Approaches to solving this problem include, among others, polar cross correlation methods and iris pattern matching/tracking. [1] [2] In animal studies, VOG has been used in combination with fluorescent marker arrays affixed to the eye, and it has been proposed that such an array could be embedded into a scleral lens for humans. [3]

  7. Eye movement in music reading - Wikipedia

    en.wikipedia.org/wiki/Eye_movement_in_music_reading

    From the start, there were basic problems with eye-tracking equipment.The five earliest studies [5] used photographic techniques. These methods involved either training a continuous beam of visible light onto the eye to produce an unbroken line on photographic paper, or a flashing light to produce a series of white spots on photographic paper at sampling intervals around 25 ms (i.e., 40 ...

  8. Visual pathway lesions - Wikipedia

    en.wikipedia.org/wiki/Visual_pathway_lesions

    The visual pathway consists of structures that carry visual information from the retina to the brain.Lesions in that pathway cause a variety of visual field defects. In the visual system of human eye, the visual information processed by retinal photoreceptor cells travel in the following way:

  9. Gaze-contingency paradigm - Wikipedia

    en.wikipedia.org/wiki/Gaze-contingency_paradigm

    In interactive mode, the eye-tracker is used as an input device. From a general point of view, an interactive system responds to the observer's actions and interacts with them. Because the display updates in response to the observer's eye movements, the gaze-contingency paradigm can be classified an interactive eye-tracking application. [1]
