Abstract: The disclosed System enables word-level text entry on a small displayed keyboard by tracing an input path that begins on or near the key of the first letter, passes through or near the key of each letter in sequence, and terminates in the vicinity of the key of the last letter. The input path is processed by scoring it against words in a database that includes an indication of relative frequency. A correctly spelled word is output even when the input path corresponds to an incorrect spelling of a word. Words are ranked according to a score calculated from the weighted distances from each associated key to determined input path points, further weighted by the frequency of use and by other characteristics of the input path. Alternate word choices are presented to the user in a manner to minimize distraction. Efficient editing mechanisms and other enhancements are included.

Abstract: A method and system of inputting alphabetic text having a virtual keyboard on a touch sensitive screen. The virtual keyboard includes a set of keys where an each letter of alphabet is associated with at least one key. The present invention allows someone to use the virtual keyboard with continuous contact of the touch sensitive screen. The user traces an input pattern for word by starting at or near the first letter in a decided word and then tracing through or near each letter in sequence. The present invention then generates a list of possible words associated with the entered part and presents it to user for selection.
