Feel the BCI vibe – vibrotactile BCI feedback

Controlling a device via a brain-computer interface (BCI) requires the participant to look and to split the attention between the device and the BCI feedback, which is partly contradictory. Therefore, a stimulation system based on 6 coin-motors is developed, which provides a tactile illusion as BCI feedback. Several experiments are conducted to optimize the illusion parameters and to check the influence on the EEG. Furthermore, 6 healthy BCI subjects compared visual with tactile feedback in online MI recordings, and no performance degradation was found.
