Benefits of technology

[0009]It is therefore an object of the present invention to provide an automatic spelling correction apparatus to reduce keystrokes.

Problems solved by technology

Mobile phones, for example, are limited to 12 buttons for input of phonetic symbols to assemble a Chinese word while the Zhu Yin Fu Hao phonetic symbol system has 37 phonetic symbols, resulting in input difficulty.
Although character entry via cycled button is functional, requiring additional keystrokes to input a phonetic symbol or an English letter may be considered by some to be inconvenient or even difficult.
It has often been argued manipulating cycled buttons is difficult due to small, difficult to read prompts.
Additionally, when an incorrect character is input, the “clear” button must be pressed to first erase the character before the correct character can be input, resulting in additional keystrokes.
Not all character combinations, however, have valid spelling.

Embodiment Construction

[0024]FIG. 2 is a schematic diagram of an apparatus for automatic spelling correction according to the invention. The apparatus comprises a storage device 21, a processing unit 22, and a display unit 23. The storage device 21 stores a character group table 211 and multiple character combination records 212, and can be a ROM, RAM, flash ROM or the like. Although the apparatus in a preferred embodiment is a handheld device, any electronic device with cycled buttons provided to input characters, such as Arabic numerals, English letters, phonetic symbols corresponding with Zhu Yin Fu Hao phonetic symbol system, or others, is applicable. The character group table 211 stores a character sequence composed of multiple characters, associated with a cycled button and an input mode.

[0025]FIG. 3 is a diagram of an exemplary character group table according to the invention. Record 32 contains three character sequences corresponding to the cycled button 12, associated with various input modes, an...

Abstract

An automatic spelling correction apparatus. The apparatus comprises a storage device and a processing unit. The storage device stores a character group table containing a character sequence of each cycled button, and multiple character combination records. A processing unit receives an original character combination and a new character, to determine whether the original character combination has a valid spelling, if not, a valid character combination matching the character combination record according to the character group table is generated.

Description

CROSS REFERENCE TO RELATED PATENT APPLICATION[0001]This patent application is a continuation application (CA) of a U.S. patent application Ser. No. 10 / 817,804 filed Apr. 6, 2004, and now pending. The contents of the related patent application are incorporated herein for reference.FIELD OF THE INVENTION[0002]The present invention relates to input correction, and more particularly to an apparatus for automatic spelling correction.BACKGROUND OF THE INVENTION[0003]Handheld devices, such as cellular phones, and PDAs, are designed to be small enough to meet mobility requirements. In order to reduce size handheld devices provide a limited number of buttons for input, and the sum of the buttons is less the total number of characters, such as English letters or phonetic symbols corresponding with Zhu Yin Fu Hao phonetic symbol system. Mobile phones, for example, are limited to 12 buttons for input of phonetic symbols to assemble a Chinese word while the Zhu Yin Fu Hao phonetic symbol system ...
