Reading is an important aspect of a child’s development. Reading outcome is heavily dependent on the level of engagement while reading. In this paper, we present FOCUS, an EEG-augmented reading system which monitors a child’s engagement level in real time, and provides contextual BCI training sessions to improve a child’s reading engagement. A laboratory experiment was conducted to assess the validity of the system. Results showed that FOCUS could significantly improve engagement in terms of both EEG-based measurement and teachers’ subjective measure on the reading outcome.
