FULL STORY

An entirely new predictive typing model can simulate different kinds of users, helping figure out ways to optimize how we use our phones. Developed by researchers at Aalto University, the new model captures the difference between typing with one or two hands or between younger and older users.

'Typing on a phone requires manual dexterity and visual perception: we press buttons, proofread text, and correct mistakes. We also use our working memory. Automatic text correction functions can help some people, while for others they can make typing harder,' says Professor Antti Oulasvirta of Aalto University.

The researchers created a machine-learning model that uses its virtual 'eyes and fingers' and working memory to type out a sentence, just like humans do. That means it also makes similar mistakes and has to correct them.

'We created a simulated user with a human-like visual and motor system. Then we trained it millions of times in a keyboard simulator. Eventually, it learned typing skills that can also be used to type in various situations outside the simulator,' explains Oulasvirta.

The predictive typing model was developed in collaboration with Google. New designs for phone keyboards are normally tested with real users, which is costly and time-consuming. The project's goal is to complement those tests so keyboards can be evaluated and optimized more quickly and easily.

For Oulasvirta, this is part of a larger effort to improve user interfaces overall and understand how humans behave in task-oriented situations. He leads a research group at Aalto that uses computational models of human behaviour to probe these questions.

'We can train computer models so that we don't need observation of lots of people to make predictions. User interfaces are everywhere today -- fundamentally, this work aims to create a more functional society and smoother everyday life,' he says.

The researchers will present their findings at the CHI Conference in May.
