Summary
There is a lack of means to input text in Indian languages in a market which is dominated by English interfaces. New text-input mechanisms have to go through a long process of prototype building and longitudinal user testing before the method is rolled out for general usability. A feasible course is to develop predictive models, which, in turn can be a beneficial mode for evaluating existing and new text entry methods.

The project involved modelling and simulation: development of an evaluation model based on Fitts’s Law (regression) in complement with key-stroke level model; Conducted user testing for Marathi language script users to predict expert level speeds across multiple competing keyboards offering similar functionality.
