Eighty-eight children (either totally blind or with residual vision) estimated directions between landmarks in a large scale layout of objects. Children experienced the layout either directly by walking around it or indirectly by examining a tactile map. Use of tactile maps considerably facilitated the performance of the blind children.

This study examined effects of visual impairment on the performance of typical educational tasks requiring visual accommodation to print material at three different distances. Subjects were 18 visually impaired and 19 nonimpaired children (ages 6-10). Findings indicated that visually impaired children exhibited more fixation shifts per task.…

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…
