Research Abstract

We have improved brain-computer interface (BCI) based on the event-related potentials (ERPs) elicited by the visual stimuli which added eye gaze detection function for the severely disabled. In the P300-type BCI, we examined the relationship between gazing point and the change of waveform of ERPs. It showed that using eye gaze information would improve the BCI. Based on the results, we have proposed a method of grouping stimuli. The proposed system would reduce user's burden in the case of the transitionto the BCI communication from the eye-gaze interface.
