Multi-command Tactile Brain Computer Interface: A Feasibility Study

Abstract

The study presented explores the extent to which tactile stimuli delivered to the ten digits of a BCI-naive subject can serve as a platform for a brain computer interface (BCI) that could be used in an interactive application such as robotic vehicle operation. The ten fingertips are used to evoke somatosensory brain responses, thus defining a tactile brain computer interface (tBCI). Experimental results on subjects performing online (real-time) tBCI, using stimuli with a moderately fast inter-stimulus-interval (ISI), provide a validation of the tBCI prototype, while the feasibility of the concept is illuminated through information-transfer rates obtained through the case study.

Multi–command Chest Tactile Brain Computer Interface for Small Vehicle Robot Navigation

“…The proposal is similar to the previously reported waist positions based tBCI reported in [1] with a difference that we propose to use the chest area simulation which simplifies a vehicular robot operation in comparison to our previous handand head-stimulus-based tBCI solutions reported in [10,9].…”

Robotic and Virtual Reality BCIs Using Spatial Tactile and Auditory Oddball Paradigms

“…This research project was an improvement of a previously reported finger stimulus tactile BCI developed also by the BCI–lab research group (Mori et al, 2013b). The direct brain–robotics interface was based on the P300 response (Donchin and Coles, 1988) classification in a tactile sensory modality (Brouwer and Van Erp, 2010).…”

“…The AUTD stimulus generator in the RautdBCI experiments delivered tactile and contactless stimuli to the user skin only via air pressure modulation using a technique of beam-forming-based focused ultrasound (Iwamoto et al, 2008; Mori et al, 2012, 2013a,b,c,d; Hamada, 2014). The AUTD stimulation effect was achieved due to a generated ultrasonic radiation static force, which was produced by an intense sound pressure amplitude.…”

Workshops of the Fifth International Brain-Computer Interface Meeting: Defining the Future

“…BCI prototypes described included a tactile-based BCI involving tactors to deliver P300 generating stimuli [156], and finger/hand [157, 158] and head/bone-conduction [159, 160] based tactile BCI prototypes.…”
