Pupil size affects measures of eye position in video eye tracking: implications for recording vergence accuracy

open access: yesJournal of Eye Movement Research, 2016
Video eye trackers rely on the position of the pupil centre. However, the pupil centre can shift when the pupil size changes. This pupillary artifact is investigated for binocular vergence accuracy (i.e. fixation disparity) in near vision where the pupil

Binocular vision and three-dimensional motion perception : the use of changing disparity and inter-ocular velocity differences [PDF]

open access: yes, 2011
This thesis investigates the use of binocular information for motion-in-depth (MID) perception. There are at least two different types of binocular information available to the visual system from which to derive a perception of MID: changing disparity ...

Changes in Binocular Color Fusion Limit Caused by Different Disparities

open access: yesIEEE Access, 2019
When the color asymmetry between the left and right eyes exceeds a threshold value, named binocular color fusion limit, the color rivalry is said to occur.

Binocular Vision: An Orientation to Disparity Coding [PDF]

open access: yesCurrent Biology, 2002
A new study has shown that neurons in the visual cortex are specialized to encode the larger range of horizontal - relative to vertical - disparities that occurs in central vision. These results challenge the established 'energy' model of disparity processing.

Do standard optometric measures predict binocular coordination during reading?

open access: yesJournal of Eye Movement Research, 2021
In reading, binocular eye movements are required for optimal visual processing and thus, in case of asthenopia or reading problems, standard orthoptic and optometric routines check individual binocular vision by a variety of tests.

Learning bio-inspired head-centric representations of 3D shapes in an active fixation setting

open access: yesFrontiers in Robotics and AI, 2022
When exploring the surrounding environment with the eyes, humans and primates need to interpret three-dimensional (3D) shapes in a fast and invariant way, exploiting a highly variant and gaze-dependent visual information.

Binocular contributions to motion detection and motion discrimination during locomotion.

open access: yesPLoS ONE
During locomotion, the visual system can factor out the motion component caused by observer locomotion from the complex target flow vector to obtain the world-relative target motion.

On the inverse problem of binocular 3D motion perception. [PDF]

open access: yesPLoS Computational Biology, 2010
It is shown that existing processing schemes of 3D motion perception such as interocular velocity difference, changing disparity over time, as well as joint encoding of motion and disparity, do not offer a general solution to the inverse optics problem ...

Binocular summation of contrast remains intact in strabismic amblyopia [PDF]

open access: yes, 2007
PURPOSE. Strabismic amblyopia is typically associated with several visual deficits, including loss of contrast sensitivity in the amblyopic eye and abnormal binocular vision.
