A novel tactile stimulation system for BCI feedback

When BCI based devices are operated, users are often desired to interact with environment. However, conventional visual BCI feedback disturbs continuous and smooth interactions. Therefore, a new tactile stimulation system suitable for delivering BCI feedback to user is developed. The system employs tactile illusion of movement to produce a continuous movement within six coin motors. Two protocols that convert the BCI feedback into spatiotemporal patterns of the stimulator are tested online. The results show that there are no identified artifacts in the EEG signal and no degradation of classification accuracy.
