I designed a unique and an easy-to-use interface and usability exploration of various Indic Script input methods for iPAQ and mobile phones, using an iterative user-centred design approach.

The average citizen in emerging markets is not computer-savvy, is fluent in the local language, and knows little or no English. The keyboard is often the most intimidating part of a computer for novice users. To make matters worse, many languages in the emerging markets including Indian languages are not keyboard-friendly.

The scripts for Indian languages are too complex or have too many symbols to be laid out on a standard keyboard, leading to the use of multiple shift modes. Pen-based interfaces and solutions will facilitate automation and access in the emerging markets. Efforts are presently focused on Indian languages and scripts with the understanding that they have broader application to the languages and scripts in the world’s emerging markets. Various input devices are being envisaged currently by various organisations to make Indic keyboard input easier. HP labs have invented some of their own. I was expected to work with user researchers and technologists to design the best in-class input methods for various user segments.

It was quite nice working with senior scientists and developers of hp. The interface has been implemented and working on iPAQ. It is rewarding to see that this project is being filed for a patent and will be published in Jan 2008.
