Outline of Final Research Achievements

A Brain-computer interface (BCI) using an event-related potential (ERP) induced by a tactile stimulus was investigated in this study. We focused on tactile sensations instead of visual and auditory sensations. Several patterns of mechanical tactile stimuli were applied to the fingers of both hands using two piezo actuators that were used as a braille display. Human experiments based on the oddball paradigm were carried out to investigate the property of recognition and discrimination for tactile stimuli. Subjects were instructed to pay attention to unusual target stimuli while avoiding other frequent non-target stimuli. We confirmed that the accuracy of the proposed method is influenced from subject’s concentration to the task and the difficulty of the task. The proposed method would be applicable to practical use from the experimental results.
