These three different vibrotactile stimulation patterns were provided to the fingertips of five healthy subjects by a small solenoid-type vibrating tactor. The five subjects, who were blindfolded, were asked to selectively focus their attention to either left or right fingertip flutter sensations, according to the audible cue given. <\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.33%\">\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"299\" height=\"230\" src=\"https:\/\/ise.ncsu.edu\/bci\/wp-content\/uploads\/sites\/7\/2016\/07\/SSSEP1.png\" alt=\"Towards Development of Steady-State Somatosensory Evoked Potentials (SSSEPs)-Based Brain-Computer Interfaces\" class=\"wp-image-20\" \/><\/figure><\/div>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"960\" height=\"400\" src=\"https:\/\/ise.ncsu.edu\/bci\/wp-content\/uploads\/sites\/7\/2016\/07\/SSSEP_Main-Copy.png\" alt=\"steady-state somatosensory evoked potentials (SSSEPs)\" class=\"wp-image-37\" srcset=\"https:\/\/ise.ncsu.edu\/bci\/wp-content\/uploads\/sites\/7\/2016\/07\/SSSEP_Main-Copy.png 960w, https:\/\/ise.ncsu.edu\/bci\/wp-content\/uploads\/sites\/7\/2016\/07\/SSSEP_Main-Copy-600x250.png 600w, https:\/\/ise.ncsu.edu\/bci\/wp-content\/uploads\/sites\/7\/2016\/07\/SSSEP_Main-Copy-768x320.png 768w\" sizes=\"auto, (max-width: 960px) 100vw, 960px\" \/><\/figure><\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:66.66%\">\n<p>The results of this study showed that small solenoid-type haptic tactors can elicit SSSEPs near the contralateral central brain areas.
