Abstract
The paper presents a tactile pressure stimulus-based brain-computer interface (BCI) paradigm. 3×3 pressure pins matrix stimulus patterns are presented to the subjects in an oddball paradigm allowing for "aha-responses" generation to attended targets. A research hypothesis is confirmed with the results with five subjects performing online BCI experiments. One of the users could score with 100% accuracy in online ten averages based BCI test. Three users scored above chance levels, while one remained on the chance level border. The presented pilot study experiments and EEG results confirm the effectiveness of the proposed tactile pressure stimulus based BCI.
