Abstract

Event Abstract Back to Event METU-BCI Studies: Development of a low cost and efficient BCI system for the disabled H. B. Erdoğan1*, Berna Akıncı1, Erman Acar1, Nevzat G. Gençer1 and A B. 1 1 Middle East Technical University, Electrical and Electronics Engineering Department, Brain Research Laboratory, Turkey Aim: The purpose of this study is to develop a low cost BCI framework for the disabled and address the possibility of such a system as a cheap and practical tool for the possible users. Methods: Beside the signal processing techniques and classification methods, the mechanisms in measurement of the brain activity and system stability during experimental paradigms are of quite importance in Brain-Computer Interfaces (BCIs). The quality of the signal detecting and recording devices considerably affect the performance of the algorithms employed in these systems. With the developments in technology, it is possible to develop assistive BCI systems with lower cost and higher efficiency. In this study, the possibility of a BCI system as a cheap and practical tool for disabled patients is addressed. Specifically, an efficient BCI framework has been designed in which a 10 channel prototype EEG system is realized using low cost hardware components and free software/firmware tools in market. Several signal processing and classification methods are implemented/integrated with various BCI applications. Results: As a completing study, a low cost P300 based BCI application has been realized exhibiting an average bit rate of 25.4bits/min in healthy subjects. Conclusion: The framework currently developed has few dependencies on expensive signal processing and hardware tools. Therefore, it can easily be donated to patients with a proper funding.
