Mechanical pointer for use with handicapped children

Abstract

For the nonverbal cerebral palsy child, communication with the outside world is a major problem. With those c.p. children who do not suffer complete limb paralysis, limb movement is at least very spastic and prevents them from using normal keyboard writing devices or instruments. During recent years a number of special communication devices have been developed for the use of such children and these range from simple mechanical systems to sophisticated, but costly, electronic systems. The paper describes a simple, inexpensive, yet useful, mechanicalpointer system for such handicapped children, which can be used for a multiaddress communications system as well as a drawing or art instrument for severely involved children.
