Abstract

This project aimed to enhance performance and usability of mental imagery-based BCIs by evaluating (1) user-appropriate and robust control strategies, (2) whether mental imagery-based BCIs are robust and stable enough for real-world applications and (3) user-comfort in able-bodied and disabled individuals. Three studies were conducted to address these issues. The results showed that alternatives to motor imagery can provide a great benefit especially to severely motor impaired users. Individually chosen control strategies from a broad range of reliable and stable mental tasks can improve BCI usability and performance substantially. Furthermore, participants could operate the BCI while simultaneously perceiving or reacting to deviant auditory stimuli and could attain stable long-time BCI control despite longer breaks without any BCI use. This project paid special attention to practical issues and helped to pave the way out of the laboratory into real-world application for mental imagery-based BCIs.
