Classification of tactile event-related potential elicited by Braille display for brain–computer interface
J Hori, N Okada�- Biocybernetics and Biomedical Engineering, 2017 - Elsevier
To construct brain–computer interface (BCI), an event-related potential (ERP) induced by a
tactile stimulus is investigated in this paper. For ERP-based BCI, visual or auditory
information is frequently used as the stimulus. In the present study, we focus on tactile
sensations to reserve their visual and auditory senses for other activities. Several patterns of
mechanical tactile stimulation were applied to the index fingers of both hands using two
piezo actuators that were used as a braille display. Human experiments based on the�…
