Abstract:
1. A reduced keyboard system for text input on an electronic device, comprising; (a) a virtuat keyboard comprising a plurality of keys; (b) an input device associated with said virtual keyboard, wherein text input is performed by placing said input device onto the virtual key of said keyboard that corresponds to the first character of a word, sliding said input device to subsequent virtual keys corresponding to subsequent characters of a word, and lifting said input device from said virtual keyboard so as to produce a bi-dimensional input pattern, and; (c) a dictionary database associated with said virtual keyboard, said dictionary database comprising a plurality of classes wherein each of said classes contain words that have first and last letters corresponding to predetermined keys of said virtual keyboard; wherein said bi-dimensional input pattern is used in order to determine the identity of the inputted word at least partially based on mathematical monotonous comparisons between said bi-dimensional input pattern and a temporary library of patterns generated from words contained within possible classes of said dictionary database to which the inputted word belongs such that inputted words are identified based on whole-word recognition.
