ABSTRACT:
Apparatus is provided for facilitating communication of a multi-symbol message by a speechless, handicapped person. The apparatus includes a plurality of independently selectable symbol indicators, preferably arranged in a matrix, and each including an electrically energizable light source such as a light emitting diode that is energized when the symbol is selected. As an aid to message composition, an individually selected one of the symbol indicators serves as a cursor. The apparatus receives signals supplied by an actuator accessory for defining commands including a cursor-move command and a record command. Upon completion of message composition, the apparatus provides for automatically selecting each symbol indicator that had served as the cursor at the time of receipt of a record command.
