Vergence Matching: Inferring Attention to Objects in 3D Environments for Gaze-Assisted Selection
International Conference on Human Factors in Computing Systems, 2023 Gaze pointing is the de facto standard to infer attention and interact in 3D environments but is limited by motor and sensor limitations. To circumvent these limitations, we propose a vergence-based motion correlation method to detect visual attention ...

The Effect of the Vergence-Accommodation Conflict on Virtual Hand Pointing in Immersive Displays
International Conference on Human Factors in Computing Systems, 2022 Previous work hypothesized that for Virtual Reality (VR) and Augmented Reality (AR) displays a mismatch between disparities and optical focus cues, known as the vergence and accommodation conflict (VAC), affects depth perception and thus limits user ...

Saccades and vergence performance in a population of children with vertigo and clinically assessed abnormal vergence capabilities. [PDF]
PLoS ONE, 2011 PURPOSE: Early studies reported some abnormalities in saccade and vergence eye movements in children with vertigo and vergence deficiencies. The purpose of this study was to further examine saccade and vergence performance in a population of 44 children (

Vergence fusion sustaining oscillations
Journal of Eye Movement Research, 2021 Introduction: Previous studies have shown that the slow, or fusion sustaining, component of disparity vergence contains oscillatory behavior. Given the delays in disparity vergence control, a feedback control system would be expected to exhibit oscillations following the initial transient period.

Central crosstalk for somatic tinnitus: abnormal vergence eye movements. [PDF]
PLoS ONE, 2010 BACKGROUND: Frequent oulomotricity problems with orthoptic testing were reported in patients with tinnitus. This study examines with objective recordings vergence eye movements in patients with somatic tinnitus patients with ability to modify their ...

Accuracy of formulae for secondary intraocular lens power calculations in pediatric aphakia
Journal of Current Ophthalmology, 2017 Purpose: To compare the accuracy of axial length vergence formulas versus refractive vergence formulas for secondary intraocular lens (IOL) implantation in pediatric aphakia. Methods: This retrospective comparative study, evaluated 31 eyes of 31 patients

Differentiation between vergence and saccadic functional activity within the human frontal eye fields and midbrain revealed through fMRI. [PDF]
PLoS ONE, 2011 Eye movement research has traditionally studied solely saccade and/or vergence eye movements by isolating these systems within a laboratory setting. While the neural correlates of saccadic eye movements are established, few studies have quantified the ...

Vergence-accommodation conflicts hinder visual performance and cause visual fatigue.
Journal of Vision, 2008 Three-dimensional (3D) displays have become important for many applications including vision research, operation of remote devices, medical imaging, surgical training, scientific visualization, virtual prototyping, and more. In many of these applications,
