Children were asked to point to familiar locations in and around their homes. Results suggest that blindness interferes with the development of spatial knowledge in which Euclidean directions between…

To develop a battery of tasks to predict and improve mobility performance, a series of functional vision tasks (texural shearing, degraded images, embedded figures, and parafoveal attention) were generated by a microcomputer. Sixty visually impaired subjects given either computerized task training or real-life training improved their low vision…
