Think and Spell

Think and Spell is a part of an overall goal to research Brain-Computer Interfaces (BCI) for use in everyday environments.

A P300 based BCI is used with a T9 ambiguous keyboard algorithm combined with context-sensitive word selection to reduce the decisions required to ‘type’ a word. This approach can significantly improve accuracies and information transfer rates.
