ALPHANUMERIC INPUT METHOD AND APPARATUS

摘要

A data input method and apparatus for inputting data are provided. The Applicants' method for inputting text includes providing the user with an apparatus comprising twelve keys. From two combinations of twelve keys, the user can produce a full set of alphanumeric text. These two combinations are referred to as chords. By monitoring and correlating a value representative of the chord combination, the user can emulate an entire 104 key keyboard. As embodied on devices which include a display device, the Applicants' method includes displaying a dynamic guide which assists the user in chord entry and completion by displaying the possible characters availabl e from a first input. The method and apparatus can be implemented on any device providing a minimum of twelve keys or a display device which allows for the representation and selection of twelve keys.
