Long Distance Walking

Prof. Anirudha Joshi from IIT Bombay visited CHEC, Kochi University of Technology, and gave a talk entitled "The story of Swarachakra - Cracking the puzzle of text input in Indian languages".

Abstract

There was a time when text input in Indian languages was called a ‘puzzle’. People found it so difficult that became a barrier that prevented them from using most other technology products, from doing common tasks such as searching the web or saving a contact. As a result, Indians typed very little in their own languages. The Roman script (in which we write English) is an Alphabet. The Japanese Kanji is logographic while Hiragana and Katakana are syllabic. In contrast, a large majority of Indian scripts are Abugidas - a different type of scripts. In our lab, we were convinced that we need different solutions - what works for Alphabets may not work for Abugidas. Over the years we explored several designs. Our early solutions were for desktop computers. Later we developed concepts for the feature phones. We tried several creative ideas and made prototypes. We got interesting results in the lab. We published papers and case studies. But beyond that, we could not reach out and make a difference to the end-users. Then smartphones arrived, and quickly became popular. It became relatively easier to develop and deploy keyboards. Again, we tried several ideas. One solution stood out in comparison with others. We called it “Swarachakra”. Today, Swarachakra is available for 12 Indian languages and has been downloaded by about 4 million users. What was the problem, and how was it solved? And what challenges remain? Come to the talk to find out.
