Tactile-force brain-computer interface paradigm

Student teaching and research laboratory focusing on brain-computer interface paradigms - A creative environment for computer science students -

“…5) Vibrotactile and Tactile-pressure BCI Paradigms: A series of successful vibrotactile [13], [14] and tactilepressure/force [16], [17] paradigms were developed with the BCI-LAB approaching a problem of communication alternatives design for those LIS patients with no vision or functional hearing (due to the so called ear stacking syndrome). In these spatial tactile projects the contributing students combined successfully their knowledge of multichannel stimulus generation systems development in MAX 6 environment [25] together with brainwave processing and classification.…”

“…The experimental focus of the non-invasive BCI lab is on the external stimulus-driven paradigms relaying on event related potential's (ERP) P300 responses [1] allowing for multi-sensory stimulation application. The sensory modalities available for experimenting are as follows, (i) spatial auditory: with multi-loudspeaker studio configurations [3]- [8] and headphone viral sound-based [9], [10]; (ii) spatial visual: P300 [4] and steady-state response-based [11], [12]; (iii) spatial tactile: realized with vibration-based P300 [13]- [15], tactile-force [16], pin-pressure [17], and airborne ultrasonic tactile display (AUTD) contactless somatosensory modality [18], [19]. Non-invasive BCIs are the most safe because the brainwave sensors are usually attached to the surface of a human head, thus such experiments, within the institutional ethical committee guidelines, are perfectly suitable for computer science students.…”
