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.
