    Coordination of Eye and Head Movements in Central Field Loss

    This project investigates the interaction between central field loss (CFL) and vestibular function.

    Sign Finder

    This project seeks to develop a computer vision-based system that allows a visually impaired traveler to find and read informational signs, such as signs labeling office doors, streets, restrooms and Exit signs.

    A Computer Vision-Based Indoor Wayfinding Tool

    The ability to navigate safely and confidently is a fundamental requirement for independent travel and access to many settings such as work, school, shopping, transit and healthcare. Navigation is particularly challenging for people with visual impairments, who have limited ability to see signs, landmarks or maps posted in the environment.

    The Role of Selective Visual Attention in Amblyopic Suppression

    Individuals with strabismus are confronted with double vision, their brain has to choose to attend to one image and ignore or suppress the other. It has been commonly suggested that a constant suppression on the non-preferred eye in strabismus is responsible for the development of amblyopia. In the current project, we study the role of top-influences of attention in amblyopic suppression and test the hypothesis that visual suppression in amblyopia may be a form of long-term attentional “neglect”.

    Alleviating interocular suppression by high-attention demand training in amblyopia

    The goal of this project is to test a hypothesis that whether or not training patients to pay more attention to the input from the amblyopic eye can overcome interocular suppression to treat amblyopia.

    Fellow Eye Deficits in Strabismic Amblyopia

    Fellow eye abnormalities have been reported in a number of psychophysical and VEP studies. The goal of this project is to characterize the fellow eye deficits.

    Grouping and Perception in Different Types of Amblyopia

    This project was to measure the neural correlates of grouping and perception in different types of amblyopia. We found that strabismus generates significant abnormalities at both early and later stages of cortical processing and, importantly, that these abnormalities are independent of visual-acuity deficits

    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

    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.
