Abstract: An interpreter based augmentive communications system ("ACS") and method for enabling handicapped individuals to generate sentences and also to control external devices. The ACS may employ auditory or visual feedback to present category and word choices to the user. With a single switch the user may select categories and words from these choices which then are stored in an input buffer to permit the construction of sentences. Alternatively, the user may select choices which permit the control of external devices such as a wheelchair by manipulating the single switch. The microprocessor controlled ACS system incorporates a simplified programming language and interpreter to permit nonprogrammers to construct user programs that are tailored to the particular needs of the individual user. In additon, as the user gains proficiency in using the ACS, the user program can be easily revised to permit more efficient and sophisticated communications.
