Abstract
The present invention, generally speaking, provides a text entry system that uses a relatively small number of keys and that is well-adapted to memorization and skill-building. In one aspect of the invention, the text entry system is based on a set of well-chosen, “morphologically significant” symbols, related in pairs, with one such symbol assigned per key. A letter is entered unambiguously by sequentially pressing multiple keys, preferably exactly two keys. In another aspect of the invention, the number of symbols in the set is fewer than the number of keys in a telephone keypad. “Extra” keys are assigned to other characters or actions, such as “space,” “period,” backspace,” and return. Different modes of operation are provided, allowing for the entry of numbers, the entry of punctuation, cursoring, etc.
