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.
