Abstract
The invention pertains to the field of Augmentative Communication Technology. The invention addresses the problem of providing a communication device for producing message output reflecting a user'"'"'s intended message which minimizes the amount of user input required to produce a message. The invention pertains to an augmentative communication system in which user input may specify attributes of a predefined subject of desired communication. Responsive to such input, a system in accordance with the invention may provide to the user a set of predefined messages which are pertinent to the specified subject. From this set of messages the user may specify a message to be produced as output for purposes of communication. Alternatively, the user may alter the specified attributes and receive a different set of predefined messages based on the revised specifications.
