    Audiom is a tool that allows blind and visually impaired individuals to view maps completely in audio. It is a web component and can be embedded into any webpage, similar to Google Maps.

    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.

    Reverberant Auditory Scene Analysis

    The world is rich in sounds and their echoes from reflecting surfaces, making acoustic reverberation a ubiquitous part of everyday life.

    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.

    Visual Functions in CVI Application

    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.
