    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.

    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.

    Reading in mTBI

    People with mTBI often complain about dificulty in reading in spite of normal results in usual eye exams. We investigate this issue by looking at accommodation and reading rate and subjective measurement of reading difficuties for a variaty of reading tasks in normal and mTBI population.

    Adaptive Visual Strategies for Individuals with Macular Degeneration

    In this project we try to gain a better understanding of what visual strategies people use to gather information in the world.

    Fovea Use During Smooth Pursuit

    There is continuing debate as to whether smooth pursuit relies on the foveation of a moving target, especially when the target is compact. Previous studies have shown that gaze is placed on the center-of-mass of a target during saccadic eye movements.
