Towards predicting task performance from EEG signals

摘要

Smart wearable devices have lead to an increased need for processing and sharing large streams of physiological data in real-time. Modern Human-Machine Interaction (HMI) systems, especially applications designed for user training and assessment (e.g., educational or smart-rehabilitation systems), should be able to track and monitor those signals and adapt their parameters accordingly in order to optimally facilitate the special needs of each individual. Towards this end, we propose a passive Brain-Computer Interface (BCI), using a wireless non-intrusive EEG sensor under a robot assisted training task designed for cognitive assessment. As part of this ongoing work, we demonstrate our initial results on predicting user's task performance, from the EEG signals, before task completion. Our findings highlight the potentials of our hypotheses as we achieve a maximum accuracy rate equal to 74% when evaluated on 69 real subjects.
