Method of inputting letter in mobile terminal through extraction of proposed letter set

摘要

Disclosed is a method of inputting letters in a mobile terminal by using letter keys each of which has at least one letter allocated thereto. In the method, after there is an input of at least two letter keys, first proposed letter sets are extracted from combinations of letters allocated to the input letter keys, and one of the extracted first proposed letter sets is selected. When there is a further input of the letter key, the first proposed letter sets are further extracted by combining the selected first proposed letter set with letters allocated to the further input letter key. One of the further extracted first proposed letter sets is selected and the selected letter set is received as input data.
