What this research studies
From your point of view, researchers will record natural, tiny eye movements while you look at images and 3-D scenes to see how each eye’s small jitters affect what you perceive. The team will run behavioral tests of stereopsis (depth perception), use precise eye-tracking to compare the two eyes, and combine those data with computational models of how the brain decodes binocular input. Some experiments probe the control of those movements to learn how the eyes are coordinated, and others examine how the changing inputs shape perception. Participation mainly involves lab visits for vision tasks and eye-movement recordings.
Who could benefit from this research
Good fit: Ideal participants are adults willing to undergo vision tests and eye-tracking, including people with typical binocular vision and those with binocular vision differences such as stereo deficits or strabismus.
Not a fit: People whose health problems are unrelated to vision, or who cannot reliably sit still for eye-tracking or follow visual task instructions, are unlikely to benefit or be eligible.
Why it matters
Potential benefit: If successful, this work could improve understanding of how binocular eye movements shape depth perception and help develop better diagnostics or treatments for binocular vision problems.
How similar studies have performed: Previous research shows fixational eye movements matter for single-eye acuity, but applying these ideas to binocular depth perception and control is a newer direction.
