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.
Most of the widely used Indic scripts are encoded in Unicode for working on Computers and Internet. As of version 10.0, Bengali, Devanagari, Gujarati, Gurmukhi, Kannada, Limbu, Malayalam, Masaram Gondi, Newari, Ol Chiki, Oriya, Sinhala, Tamil and Telugu scripts are encoded and supported. Historically used writing systems like Arwi, Ahom alphabet, Grantha, Khudabadi, Mahajani, Modi alphabet, Siddham script, Syloti Nagri, Tirhuta are also included. Some more Indic scripts are in development and will be included in unicode, for instance Tulu Script.
A lot of Indic Computing projects are going on. They involve some government sector companies, some volunteer groups and individual people.

Full size keyboards
With the advent of Unicode inputting Indic text on computer has become very easy. A number of methods exist for this purpose, but the main ones are:-
Inscript is the standard keyboard for Indian languages. Developed by C-DAC and standardized by Government of India. Nowadays it comes inbuilt in all major operating systems including Microsoft Windows (2000, XP, Vista, 7), Linux and Macintosh.
This is a typing method in which, for instance, the user types text in an Indian language using Roman characters and it is phonetically converted to equivalent text in Indian script in real time. This type of conversion is done by phonetic text editors, word processors and software plugins. Building up on the idea, one can use phonetic IME tools that allow Indic text to be input in any application.
Some examples of phonetic transliterators are Xlit, Google Indic Transliteration, BarahaIME, Indic IME, Rupantar, SMC's Indic Keyboard and Microsoft Indic Language Input Tool. SMC's Indic Keyboard has support for as many as 23 languages whereas Google Indic Keyboard only supports 11 Indian languages.
They can be broadly classified as:
- Fixed transliteration scheme based tools - They work using a fixed transliteration scheme to convert text. Some examples are Indic IME, Rupantar and BarahaIME.
- Intelligent/Learning based transliteration tools - They compare the word with a dictionary and then convert it to the equivalent words in the target language. Some of the popular ones are Google Indic Transliteration, Xlit, Microsoft Indic Language Input Tool and QuillPad.
This layout was developed when computers had not been invented or deployed with Indic languages, and typewriters were the only means to type text in Indic scripts. Since typewriters were mechanical and could not include a script processor engine, each character had to be placed on the keyboard separately, which resulted in a very complex and difficult to learn keyboard layout.
With the advent of Unicode, the Remington layout was added to various typing tools for sake of backward compatibility, so that old typists did not have to learn a new keyboard layout. Nowadays this layout is only used by old typists who are used to this layout due to several years of usage. One tool to include Remington layout is Indic IME. A font that is based on the Remington keyboard layout is Kruti Dev. Another online tool that very closely supports the old Remington keyboard layout using Kruti Dev is the Remington Typing tool.
Mobile phones with Numeric keyboards
Mobile/Hand/cell phone basic models have 12 keys like the plain old telephone keypad. Each key is mapped to 3 or 4 English letters to facilitate data entry in English. For inputting Indian languages with this kind of keypad, there are two ways to do so. First is the Multi-tap Method and second uses visual help from the screen like Panini Keypad. The primary usage is SMS. 140 characters size used for English/Roman languages can be used to accommodate only about 70 language characters when Unicode Proprietary compression is used some times to increase the size of single message for Complex script languages like Hindi. A research study of the available methods and recommendations of proposed standard was released by Broadband Wireless Consortium of India (BWCI).
In native methods, the letters of the language are displayed on the screen corresponding to the numeral keys based on the probabilities of those letters for that language. Additional letters can be accessed by using a special key. When a word is partially typed, options are presented from which the user can make a selection.
Smart phones with Qwerty keyboards
Most smart phones have about 35 keys catering primarily to English language. Numerals and some symbols are accessed with a special key called Alt. Indic input methods are yet to evolve for these types of phones, as support of Unicode for rendering is not widely available.
For Smart Phones with Soft/Virtual keyboards
Inscript is being adopted for smart phone usage. For Android phones which can render Indic languages, Swalekh Multilingual Keypad Multiling Keyboard app are available. Gboard offers support for several Indian languages.
Localization means translating software, operating systems, websites etc. various applications in Indian language. Various volunteers groups are working in this direction.
Mandrake Tamil Version
A notable example is the Tamil version of Mandrake linux. Tamil speakers in Toronto(Canada) released Mandrake, a GNU/Linux software, in coming out with a Tamil version. It can be noted that all the features can be accessed in Tamil. By this, the prerequisite of English knowledge for using computers has been eliminated, for those who know Tamil.
IndLinux is a volunteer group aiming to translate the Linux operating system into Indian languages. By the efforts of this group, Linux has been localized almost completely in Hindi and other Indian languages.
Indic blogging refers to blogging in Indic languages. Various efforts have been done to promote blogging in Indian languages.
Some Social networks are started in Indian languages.
Indic programming languages
Google offers improved translation feature for Hindi, Bengali, Marathi, Tamil, Telugu, Gujarati, Punjabi, Malayalam and Kannada Microsoft also offers translation for some of these languages.
Transliteration tools allows users to read a text in different script. As of now, Aksharamukha is the tool which allows most Indian scripts. Google also offers Indic Transliteration. Text from any of these scripts can be converted to any other scripts and vice versa. Whereas Google and Microsoft allow transliteration from Latin letters to Indic scripts.
Carnegie Mellon University, in collaboration with the Hear2Read project, has developed a text-to-speech (TTS) software that helps the visually impaired listen to text in native Indian languages. Currently, Tamil is being offered and , releases in Hindi, Bengali, Gujarati, Marathi, Kannada, Punjabi and Telugu are expected over the remainder of 2016.
Internationalized Domain Names
Usage and Growth
According to GoDaddy, Hindi, Marathi and Tamil languages accounted for 61% of India's internet traffic. It is to be noted that less than 1% of online content is in Indian languages. The newly created top apps have support for multiple Indian languages and/or promote Indian language content. 61% of the Indian users of WhatsApp primarily use their native languages to communicate with it. A recent study revealed that adoption of Internet is highest among local languages such as Tamil, Hindi, Kannada, Bengali, Marathi, Telugu, Gujarati and Malayalam. It estimates that Marathi, Bengali, Tamil, and Telugu will form 30% of the total local-language user base in the country. Currently, Tamil at 42% has the highest Internet adoption levels, followed by Hindi at 39% and Kannada at 37%.
