  • Patent number: 4795348
    Abstract: A communication aid that is useful to individuals who have lost the ability to communicate with other individuals by talking and/or writing. The communication aid includes a generally flat plate or panel which carries thereon a plurality of short message portions, such as words or phrases in human readable form. A plurality of manually placeable tokens are provided. Each token carries a sequence indicator, such as a number or letter, thereon. The handicapped individual selectively places a number of these tokens on the plate in a sequence, so as to communicate a message logically readable by individuals who observe the plate. This complete message is composed by reading the short message portions in the sequential order of the numbers or letters that are carried by the tokens, to thereby form the long message.
