Abstract: There is provided a method for inputting a Chinese word based on a first-input Chinese character, the method comprising: receiving a first-input Chinese character of a first letter of a target word from a user; displaying at least some of recommended Chinese words on a word-recommending interface of a device, wherein each recommended Chinese word is composed of at least one letter and has a letter including the first-input Chinese character; and displaying a Chinese word selected from the recommended Chinese words by the user on a selected-word display interface of the device.

Abstract: Provided is a keyboard for typing Chinese character, which includes a first base unit key group including subgroups of base unit keys having similar shapes to each other, a second base unit key group including base unit keys having symmetrical shapes with each other, and a third base unit key group including subgroups of base unit keys which are different from the base unit keys included in the first base unit key group and having similar shapes to each other.

Abstract: A character input method includes receiving an input of at least one base shape and a base shape input signal from a user, generating a root shape by combining the at least one base shape input before the input of the base shape input signal, according to the input of the base shape input signal, receiving an input of an input complete signal from the user, and generating a character by combining the at least one root shape generated before the input of the input complete signal, according to an input of the input complete signal.
