First Claim
1. A continuous input device for use in a sequential word generation system, the continuous input device providing input of a plurality of polysemous symbols, in selected sequences, to access prestored words and concurrently providing input of a plurality of alphabetic characters, in selected sequences, corresponding to non-prestored words, without the need of a mode selection key utilizable solely for selection among a plurality of input modes, the device comprising:

storage means, operatively connected to said key input means, for sequentially storing input polysemous symbols as a symbol sequence and for separately and concurrently sequentially storing input alphabetic characters as a character string;
comparison means, operatively connected to said storage means, for comparing said stored symbol sequence, upon storage of each polysemous symbol in the stored symbol sequence, to a plurality of predetermined symbol sequences to determine a symbol sequence match; and
input mode automatic selection means, operatively connected to said storage means, comparison means, and key input means, for automatically selecting a symbol mode and utilizing said stored input symbol sequence to subsequently access stored information for subsequent output upon said comparison means determining a symbol sequence match and for automatically selecting a character mode and utilizing said stored input character string upon the input symbol sequence being of a predetermined length and upon said comparison means not determining a symbol sequence match.

Abstract
A continuous input system allows a system operator to continuously input a plurality of polysemous icon symbols to access stored morphemes, words, phrases, or sentences corresponding to an icon sequence. The system, with automatic mode selection for the input system, containing a plurality of character and symbol keys, allows for automatically selecting of the icon mode, a character or word prediction mode, and even a subsequent suffix mode, to allow a user to enter morphemes, words, phrases, or sentences sequentially. Further, by utilizing the character and word prediction modes, including the suffix mode, words, phrases or sentences corresponding to non-accessible icon sequences can be automatically activated without having to manually switch out of the icon mode or select the character and word prediction mode. Such automatic icon, word prediction, character and suffix mode selecting, thereby allows continuous text or speech generation with a minimal number of input key activations necessary for a system operator.
