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…
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…
