    Tracking a target in depth with central field loss

    Bilateral field loss due to maculopathy creates a scotoma that extends in depth — a volume scotoma. Morevoer the size of the scotoma depends on whether observers turn their eyes to track a target as it comes closer. This project investigates how the volume scotoma affects the ability to track oncoming targets in these individuals, and in controls with a simulated volume scotoma.

    Patterns of Visual Deficits in Amblyopia

    Background Amblyopia means blunted sight in the Greek language and is a term clinicians use to describe decreased vision usually in one eye most commonly due to a focusing error (refractive error in one eye, very different from other eye - anisometropia) and/or a misalignment between the two eyes (strabismus or squint). Amblyopia is sometimes called “lazy eye”. This is different than being just near or far sighted which is a refractive error usually similar and in both eyes developing at any age and vision improves instantly on prescribing and wearing spectacles to correct the error.

    Cerebral Visual Impairment (CVI): An in-depth study of visual functioning in everyday life

    The purpose of this research study is to learn about how cerebral visual impairment affects everyday visually guided behaviours and determine interventions to treat the difficulties. This study is conducted remotely through telephone or video link and also in person at the laboratory.

    Harnessing the Power of Drawing for the Enhancement of Learning across Levels of Vision Function

    Recent scientific findings about art and drawing suggest that drawing can facilitate learning in a wide variety of domains. The proposed collaboration will develop an interdisciplinary research program aimed at harnessing the power of drawing to enhance learning across fields of intellectual endeavor.

    Advanced Spatiomotor Rehabilitation for Navigation in Blindness & Visual Impairment

    Successful navigation requires the development of an accurate and flexible mental, or cognitive, map of the navigational space and of the route trajectory required to travel from the current to the target location. The Cognitive-Kinesthetic (C-K) Rehabilitation Training that we have developed in the preceding period utilizes a unique form of blind memory-guided drawing to develop cognitive mapping to a high level of proficiency.

    Investigating Reading in Individuals with Cerebral Visual Impairment (CVI)

    In this project, we aim to understand (i) how CVI affects reading, (ii) how current rehabilitation techniques or assistive technologies help improve reading in CVI and (iii) what more can be done to assist those individuals with CVI

    Human Echolocation

    What is echolocation? Sometimes, the surrounding world is too dark and silent for typical vision and hearing. This is true in deep caves, for example, or in murky water where little light penetrates.
