A novel wireless dry EEG brain-controlled wheelchair with five steering behaviours is devised, which is based on two-stage control strategies combining sustained and brief motor imagery brain-computer interfaces (SB-MI-BCIs). Compared with the existing single modal brain-computer interface (S-BCI) controlled wheelchair, this new wheelchair has achieved more control commands and higher information transfer rate. Compared with their previous hybrid BCIs controlled wheelchair, subjects can control the wheelchair spontaneously and efficiently just by imagining the left hand, the right hand or both hands without any other visual attentions (e.g. P300 or SSVEP). The experimental results demonstrate that the SB-MI-BCIs can efficiently provide multiple independent control signals for wheelchair navigation.
