In order to support patients with motor disfunctions, we proposed brain-machine interface technology based on the characteristics of tactile sensory EEG. As an index to determine the presence or absence of conscious attention, propagation velocity vectors were calculated based on the relative time lag between EEG signals measured from three electrodes located in an equilateral triangle. It was found that the EEG response signal to the subject's finger sensory stimulation propagated to the right direction in the occipital region, but the propagation changed to the upper left direction by conscious attention.
