Embodiment Construction

[0025] Disclosed herein is a keyboard input method and device for inputting language symbols forming words such as Chinese characters with a small number of keys on a simplified keyboard, wherein a plurality of characters correspond to combinations of symbols or character strokes including letters and numbers. The user obtains the desired symbol on the display screen by pressing the keys on the keyboard for an appropriate number of times to enter the symbol. This symbol can be a stroke associated with the final desired character or an alphanumeric symbol associated with a set of symbols. A commonly used sequence of symbols associated with the Chinese language is called a pinyin sequence. When the user inputs another symbol to complete a word or character, the method or device displays the character corresponding to the symbol in the form of a 3×3 matrix. The 3×3 matrix displayed on the display screen corresponds to or maps to the keys of the keyboard on the device, and allows...

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 3x3 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 3x3 matrix to match the at least 3x3 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.

Description

technical field [0001] The present invention generally relates to entering characters into electronic devices using a keypad, and more particularly to entering Chinese characters using a telephone keypad. Background technique [0002] Portable handheld communication devices, such as cellular radiotelephones, typically have few keys for entering information, such as texts such as short messages or e-mails. A typical keypad for a handheld wireless communication device is a standard telephone keypad with ten numeric keys, an asterisk (*) key, and a pound (#) key. For English and many other alphabetic languages, the phone's numeric keypad is overlaid by an alphabetic keypad, where three or more letters of the alphabet are associated with each numeric key. For example, the number 5 key is associated with the letters j-k-l. In some electronic devices with simplified keyboards, after entering the letter input mode, the user inputs letters by pressing the keyboard multiple times t...
