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 available to them. 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 the user to type on the numeric keypad to enter Latin alphabet characters (or any other alphabet characters) or touch a screen display to input text. On some operating systems, an input method is also used to define the behavior of the dead keys.

Although originally coined for CJK (Chinese, Japanese and Korean) computing, the term is now sometimes used generically to refer to a program to support the input of any language. To illustrate, in the X Window System, the facility to allow the input of Latin characters with diacritics is also called an input method.
On Windows XP or later Windows, Input method, or IME, are also called Text Input Processor, which are implemented by the Text Services Framework API.
While the term input method editor was originally used for Microsoft Windows, its use has now gained acceptance in other operating systems[ citation needed ], especially when it is important to distinguish between the computer interface and implementation of input methods, or among the input methods themselves, the editing functionality of the program or operating system component providing the input method, and the general support of input methods in an operating system. This term has, for example, gained general acceptance on the Linux operating system; it is also used on the Mac OS.
Several input methods allow the use of Chinese characters with computers. Most allow selection of characters based either on their pronunciation or their graphical shape. Phonetic input methods are easier to learn but are less efficient, while graphical methods allow faster input, but have a steep learning curve.
The Cangjie input method is a system for entering Chinese characters into a computer using a standard computer keyboard. In filenames and elsewhere, the name Cangjie is sometimes abbreviated as cj.
The International Alphabet of Sanskrit Transliteration (IAST) is a transliteration scheme that allows the lossless romanisation of Indic scripts as employed by Sanskrit and related Indic languages. It is based on a scheme that emerged during the 19th century from suggestions by Charles Trevelyan, William Jones, Monier Monier-Williams and other scholars, and formalised by the Transliteration Committee of the Geneva Oriental Congress, in September 1894. IAST makes it possible for the reader to read the Indic text unambiguously, exactly as if it were in the original Indic script. It is this faithfulness to the original scripts that accounts for its continuing popularity amongst scholars.
The writing system of the Korean language is a syllabic alphabet of character parts organized into character blocks representing syllables. The character parts cannot be written from left to right on the computer, as in many Western languages. Every possible syllable in Korean would have to be rendered as syllable blocks by a font, or each character part would have to be encoded separately. Unicode has both options; the character parts ㅎ (h) and ㅏ (a), and the combined syllable 하 (ha), are encoded.
Simplified Cangjie, known as Quick or Sucheng is a stroke based keyboard input method based on the Cangjie IME but simplified with select lists. Unlike full Cangjie, the user enters only the first and last keystrokes used in the Cangjie system, and then chooses the desired character from a list of candidate Chinese characters that pops up. This method is popular in Taiwan and Hong Kong, the latter in particular.
Predictive text is an input technology used where one key or button represents many letters, such as on the physical numeric keypads of mobile phones and in accessibility technologies. Each key press results in a prediction rather than repeatedly sequencing through the same group of "letters" it represents, in the same, invariable order. Predictive text could allow for an entire word to be input by single keypress. Predictive text makes efficient use of fewer device keys to input writing into a text message, an e-mail, an address book, a calendar, and the like.
In human–computer interaction, a cursor is an indicator used to show the current position on a computer monitor or other display device that will respond to input.
The pinyin method refers to a family of input methods based on the pinyin method of romanization.
Japanese input methods are used to input Japanese characters on a computer.
A Unicode font is a computer font that maps glyphs to code points defined in the Unicode Standard. The vast majority of modern computer fonts use Unicode mappings, even those fonts which only include glyphs for a single writing system, or even only support the basic Latin alphabet. Fonts which support a wide range of Unicode scripts and Unicode symbols are sometimes referred to as "pan-Unicode fonts", although as the maximum number of glyphs that can be defined in a TrueType font is restricted to 65,535, it is not possible for a single font to provide individual glyphs for all defined Unicode characters. This article lists some widely used Unicode fonts that support a comparatively large number and broad range of Unicode characters.
Language input keys, which are usually found on Japanese and Korean keyboards, are keys designed to translate letters using an input method editor (IME). On non-Japanese or Korean keyboard layouts using an IME, these functions can usually be reproduced via hotkeys, though not always directly corresponding to the behavior of these keys.
A text entry interface or text entry device is an interface that is used to enter text information in an electronic device. A commonly used device is a mechanical computer keyboard. Most laptop computers have an integrated mechanical keyboard, and desktop computers are usually operated primarily using a keyboard and mouse. Devices such as smartphones and tablets mean that interfaces such as virtual keyboards and voice recognition are becoming more popular as text entry systems.
Indic Computing means "computing in Indic", i.e., Indian Scripts and Languages. It involves developing software in Indic Scripts/languages, Input methods, Localization of computer applications, web development, Database Management, Spell checkers, Speech to Text and Text to Speech applications and OCR in Indian languages.
Unicode input is the insertion of a specific Unicode character on a computer by a user; it is a common way to input characters not directly supported by a physical keyboard. Unicode characters can be produced either by selecting them from a display or by typing a certain sequence of keys on a physical keyboard. In addition, a character produced by one of these methods in one web page or document can be copied into another. In contrast to ASCII's 96 element character set, Unicode encodes hundreds of thousands of graphemes (characters) from almost all of the world's written languages and many other signs and symbols besides.
The Intelligent Input Bus is an input method (IM) framework for multilingual input in Unix-like operating-systems. The name "Bus" comes from its bus-like architecture.
Google IME, also known as Google Input Tools, is a set of input method editors by Google for 22 languages, including Amharic, Arabic, Bengali, Chinese, Greek, Gujarati, Hindi, Japanese, Kannada, Malayalam, Marathi, Nepali, Persian, Punjabi, Russian, Sanskrit, Serbian, Tamil, Telugu, Tigrinya, and Urdu. It is a virtual keyboard that allows users to type in their local language text directly in any application without the hassle of copying and pasting.
A keyboard layout is any specific physical, visual, or functional arrangement of the keys, legends, or key-meaning associations (respectively) of a computer keyboard, mobile phone, or other computer-controlled typographic keyboard.
Bengali input methods refer to different systems developed to type the characters of the Bengali script for Bengali language and others, using a typewriter or a computer keyboard.
The Vietnamese language is written with a Latin script with diacritics which requires several accommodations when typing on phone or computers. Software-based systems are a form of writing Vietnamese on phones or computers with software that can be installed on the device or from third-party software such as UniKey. Telex is the oldest input method devised to encode the Vietnamese language with its tones. Other input methods may also include VNI and VIQR. VNI input method is not to be confused with VNI code page.
MessagEase is an input method and virtual keyboard for touchscreen devices. It relies on a new entry system designed by Saied B. Nesbat, formatted as a 3x3 matrix keypad where users may press or swipe up, down, left, right, or diagonally to access all keys and symbols. It is a keyboard that was designed for devices like cell phones, mimicking the early cell phones' limited number of 12 keys.
Our top story of 2012 involves a formerly little-known app called Fleksy and its rise toward prominence and mainstream acceptance.
Word prediction is used to speed up the text entry. The prediction system uses the context of the sentence to predict three words that could be used next.
