Haptic BCI Paradigm based on Somatosensory Evoked Potential

TL;DR

This paper introduces a low-cost, open-source haptic BCI paradigm utilizing somatosensory evoked potentials, featuring a novel hardware-software setup and dry EEG electrodes for improved comfort, demonstrated through real-time online experiments.

Contribution

It presents a new haptic BCI paradigm with open-source components, novel stimuli delivery hardware, and the use of dry EEG electrodes for enhanced user comfort.

Findings

Successful online implementation with five subjects

Improved comfort using dry EEG electrodes

Potential for real-time BCI applications

Abstract

A new concept and an online prototype of haptic BCI paradigm are presented. Our main goal is to develop a new, alternative and low cost paradigm, with open-source hardware and software components. We also report results obtained with the novel dry EEG electrodes based signal acquisition system by g.tec, which further improves experimental comfort. We address the following points: a novel application of the BCI; a new methodological approach used compared to earlier projects; a new benefit for potential users of a BCI; the approach working online/in real-time; development of a novel stimuli delivery hardware and software. The results with five healthy subjects and discussion of future developments conclude this submission.
