We evaluated the keyboards with participants with low-level of education through a first-time usability test and a longitudinal usability test. One of the logically structured keyboards started out with significantly higher success rate, typing speed, and lesser errors than the other two. The longitudinal test involving text input of 500 words did not conclusively prove that either design was better. Our study establishes benchmarks for text input speeds, errors and ratings for the initial learning phase for text input in Marathi among …
