The architecture of software interface for BCI system

Abstract

The basic idea of Brain Computer Interface (BCI) is the connection of brain waves with an output device through some interface. Aim of this article is to clarify the potential utilization of complex EEG signal in BCI system. For this purpose, the architecture of the software interface was designed and tested. The main task of the interface is to transfer brain activity signal into commands of intelligent robot. The paper is organized as follows. Firstly, there is a physiological description of the human brain, which summarizes current knowledge and also points out its complexity. The basic principle of BCI system is also explained. Secondly, the specification of used technical equipment (hardware component and software tools) is provided. Thirdly, the transfer operation is explained in the description of proposed software interface. Moreover, results of interface tests are also presented. Finally, discussion deals with the advantages and disadvantages of BCI system and its usage in real-time applications.
