Abstract

Disclosed is a method and apparatus for conveniently inputting characters and inputting characters as many as possible with a limited number of keys.

Description

technical field [0001] The present invention relates to a method and device for inputting as many characters as possible with a limited number of keys. Background technique [0002] Advanced semiconductor technologies have enabled more compact and high-performance portable terminals such as mobile phones and personal digital assistants (PDAs). However, their input devices are a hindrance because these compact portable terminals require as many input keys as a computer keyboard. Contents of the invention [0003] technical problem [0004] In order to overcome this obstacle, a conventional portable terminal has a computer keyboard whose size is reduced as much as possible. However, there is a limit to reducing the size of the keyboard. [0005] technical solution [0006] The present invention provides a method and apparatus for inputting all characters provided on a computer keyboard using a limited number of keys. [0007] Additional technical features of the present...
