Tactile Graphics Helper (TGH)
Tactile graphics use raised lines, textures, and elevations to provide individuals with visual impairments access to graphical materials through touch.

Computer Vision Journal Club
The Computer Vision Journal Club meets periodically to discuss papers on topics in computer vision, machine learning and other topics of interest such as assistive technologies for persons who are blind or visually impaired, dual sensory loss (hearing and vision loss), neuroscience and psychophys

Characteristics of Smooth Pursuit in Individuals with Central Field Loss
This project investigates the properties of smooth pursuit eye movements in individuals with macular degeneration. Commonly believed to be a fovea-linked eye movement, smooth pursuit has not been previously investigated in individuals with central field loss, despite its importance for tracking moving objects, such as vehicles or pedestrians on a busy street.

Eye Movements and Accommodation Patterns in Strabismus
Strabismus misaligned eyes is a common developmental condition in young children that can lead to amblyopia or poor vision and other forms of low vision. This project looks at the eye movements in relation to accommodation or focusing power in these patients to determine predictors of strabismus and outcome of treatment, with the goal of improving early detection, intervention and treatment.

CamIO
CamIO (short for “Camera Input-Output”) is a system to make physical objects (such as documents, maps, devices and 3D models) accessible to blind and visually impaired persons, by providing real-time audio feedback in response to the location on an object that the user is touching.

Go and Nogo Decision Making
The decision to make or withhold a saccade has been studied extensively using a go-nogo paradigm, but little is known about the decision process underlying pursuit of moving objects. Prevailing models describe pursuit as a feedback system that responds reactively to a moving stimulus.

Integration and Segregation
Traditionally, smooth pursuit research has explored how eye movements are generated to follow small, isolated targets that fit within the fovea. Objects in a natural scene, however, are often larger and extend to peripheral retina.

Acoustic Cues for Wayfinding
This project aims to do a detailed analysis of the environmental acoustic cues that help some blind navigate successfully.

Learning in the Sighted and the Blind through Different Sensory Modalities: Structure and Dynamics of Cortical Reorganization
This project focuses on the emerging area of the neuroscience of art learning. It addresses the important issue of how the brain learns complex skills, specifically the process of drawing, through two different sensory modalities.

Human Oculomotor Functions & Their Deficits in Traumatic Brain Injury
Recent studies have established that a high proportion of patients diagnosed with mild (or diffuse) traumatic brain injury (mTBI) exhibit binocular vision dysfunctions, particularly, deficiencies in the binocular coordination of eye movements.

Encoding of 3D Structure in the Visual Scene: A New Conceptualization
The multidisciplinary goal was to develop an integrated conceptualization of the mid-level encoding of 3D object structure from multiple surface cues
