Wheelchair control by elderly participants in a virtual environment with a brain-computer interface (BCI) and tactile stimulation.

•Elderly participants performed a five session tactile ERP-BCI training.•Training significantly increased underlying EEG features used for BCI control.•Mean accuracies above 95% and mean ITR above 20bitsmin1 were achieved.•Highest combination of mean accuracy and speed ever reported for a tactile BCI.
