VIRTUAL KEYBOARD SYSTEM WITH AUTOMATIC CORRECTION

摘要

An enhanced text entry system (100) which uses word-level analysis to correc t inaccuracies automatically in user keystroke entries on reduced-size or virtual keyboards (105). A method and system determine alternate textual interpretations of each sequence of inputs detected within a designated auto - correcting region (106). The actual interaction locations for the keystrokes may occur outside the boundaries of the specific keyboard key regions associated with the actual characters of the word interpretations proposed, where the distance from each interaction location to each corresponding intended character may increase with the expected frequency of the intended word in the language. Likewise, in a virtual keyboard system, the keys actuated may differ from the keys actually associated with the letters of th e word interpretations. Each such sequence corresponds to a complete word, and the user can easily select the intended word from among the generated interpretations.
