Education
Visual accessibility—how effectively vision can be used to travel safely through or complete activities within a space—has an important impact on low-vision mobility. In this seminar, Gordon Legge will describe an empirical approach for studying the visual accessibility of indoor spaces, including experiments on the detection and recognition of steps and ramps. He will also outline the development of a new form of adaptive technology—the Digital Sign System—to assist visually impaired people with indoor navigation.
