The study explores the extent to which tactile-force stimulus delivered to a hand holding a joystick can serve as a platform for a BCI. The four pressure directions are used to evoke tactile brain potential responses, thus defining a tactile-force brain computer interface (tfBCI). The brain signal processing and classification procedures lead to successful interfacing results. Experimental results with seven subjects performing online BCI experiments validate the hand location tfBCI paradigm, while the feasibility of the concept is illuminated through remarkable information-transfer rates.
