What is Input: Definition and 615 Discussions

An input method (or input method editor, commonly abbreviated IME) is an operating system component or program that enables users to generate characters not natively available on their input devices by using sequences of characters (or mouse operations) that are natively available on their input devices. Using an input method is usually necessary for languages that have more graphemes than there are keys on the keyboard.
For instance, on the computer, this allows the user of Latin keyboards to input Chinese, Japanese, Korean and Indic characters. On hand-held devices, it enables using the numeric keypad to enter Latin alphabet characters (or any other alphabet characters) or a screen display to be touched to do so. On some operating systems, an input method is also used to define the behaviour of the dead keys.
