Abstract: A method and system of inputting data, including language and other forms of communication, into an electronic device is disclosed. The method and system are directed to reducing the number of keystrokes that a disabled person would need to make to use a computer or alternative communication device. The method and system according to the invention utilizes a virtual keyboard upon which a user makes an input pattern or “gesture”. The gesture is then transformed into a ranked list of language unit prefixes. Word prediction analysis then analyzes the list of language unit prefixes and develops a list of potential word or phrases that the user may select from.
