References 184losing vision is a significant decrement in performance of actions that rely on
the spatial resolution and wide field of view that vision provides, particularly under tight temporal constraints (see Chapters 2 and 4). Returning a
tennis serve or driving in city traffic are examples. Nonetheless, the ability of
many blind people to perform tasks that we generally think of as visually
guided, like steering a bicycle around obstacles (using echolocation), is testimony to the potential of other sources of information to substitute for visual
input. This form of sensory substitution, allowing one or more of the remaining spatial senses to take the place of vision, is possible because hearing and
touch are also informative about the environment. Expanding these natural
sensory substitutions with compensatory strategies and theoretically motivated technologies would no doubt enhance the capabilities of blind and
low-vision individuals.
