  • Publication number: 20090164891
    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.
