P300-based brain-computer interface memory game to improve motivation and performance

A brain-computer interface (BCI) relies on a classifier to determine a user's intent through the EEG signals. This classifier needs to be trained with a specific user prior to its usage. Since the effectiveness of a classifier is affected by the user's motivation during training, a memory game using the BCPy2000 platform has been developed for enhancing motivation and performance in using a traditional P300-based BCI system. A pilot study showed that this memory game is accomplishable by human subjects in a BCI system.
