The Evaluation of a Brain Computer Interface System with Acquired Brain Injury End Users

This paper focuses on the evaluation of a P300 BCI prototype to migrate from the lab to the home of people with acquired brain injury (ABI). Our evaluation involved both, end users and healthy controls. Overall, lower accuracy scores were recorded for the end-user group (55%) compared to 78% in the control group. The findings further indicate that participants were satisfied with the BCI but felt frustrated when it did not respond to their input. Overall, our evaluation indicated that BCI systems can work for people with ABI and the results will inform the development of subsequent prototypes.
