Abstract
A method and apparatus for character entry and more particularly Chinese character entry. The method improves the ease of entry for Chinese characters on a device that has a keypad arrangement of at least a 3×3 matrix (106). For example wireless communication devices such as radiotelephones have a keypad (108) for dialing phone numbers. Arranging the Chinese characters on the device display in a 3×3 matrix to match the at least 3×3 matrix of the keypad allows the user to quickly select from the pinyin list (104) the key on the keypad that corresponds to the desired character in the matching matrix.
