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.
