Abstract:Most research on Brain-Computer Interfaces (BCI) focuses on developing ways of expression for disabled people who are not able to communicate through other means. Recently it has been shown that BCI can also be used in games to give users a richer experience and new ways to interact with a computer or game console. This thesis describes the research conducted to find out what the differences are in user experience between actual and imagined movement as paradigms in a BCI game. A group of twenty subjects played the game BrainBasher controlling their actions in the game purely with brain waves. Questionnaires were administered throughout the whole experiment to measure user experience. BrainBasher also yielded a statistic on how well people were able to control the game. The questionnaire was corrected for internal consistency and used to evaluate the differences. Results showed that users found more challenge in imagined movement but at the same time stayed more alert when performing actual movement. Furthermore the brain activity related with actual movement was found to be better recognizable by the classiffication pipeline used by BrainBasher.
