Aids for the blind

In the United States some 1,500 veterans of World War II and a total of approximately 240,000 persons are handicapped by loss of vision. Much has been done to aid these individuals, but the present occupational fields open to them are very limited. Development of suitable instruments for measuring and computing, guidance devices, and devices for reading printed material; and creation in the mind of industry a better attitude on capabilities of the blind are of major importance in their aid. Some progress has been made, but in order to overcome the limited application of Braille and the handicaps involved with guide dogs mechanical and electric equipment is being developed and refined.
