At some point, I hope that a single de facto Korean mobile keyboard array emerges, such

as what has happened in Japan. Given the somewhat volatile nature of the mobile device

market, along with the complexity of hangul, it may be years until a de facto Korean mo-

bile keyboard array emerges. However, if I were to guess based solely on market share,

ease and intuitiveness of input, and other factors, Samsung’s Chonjiin Hangul seems like

the best candidate for the de facto standard.

Other Input Hardware

What has been described so far falls into the category of keyboard arrays—that is, keys that

are used to input kana, hangul, Latin, or other characters. Other more recent hardware

methods, such as pen input, do not require use of conventional keys. Optical Character

Recognition (OCR) is another input system that deals with the problem of transcribing

already printed information. Finally, there are voice input systems.

is area is rapidly changing. Since the rst edition of this book was published, OCR

and voice recognition systems have advanced signicantly. Interestingly, pen input hasn’t

quite taken o, and at this ...
