Conceptual design of BCI in the formal basis of Hierarchical System

Abstract

The use of Hierarchical Systems (HS) technology in conceptual design of BCI is proposed in the work. Being biomechatronic by nature BCI system contains, biological (brain), computer, visual informatics (LCD, GUI), electronic (sensors) and executive mechanical (mobile robot) or virtual mechanical (virtual keyboard) subsystems. So, conceptual model of the BCI system being designed should contain connected systemic models of the above subsystems presented in the general formal basis. The BCI system structure, its dynamic presentation as the unit in its environment and BCI environment should be also described in this basis. Inter-level dynamics fulfilled by system-environment (e.g., brain-computer) interactions have to be taken into account by BCI Conceptual Model as well. Traditional models of mathematics and AI do not allow such a description. So, aed model of HS was chosen as theoretical basis of BCI Conceptual Model development in the work. Results of BCI detailed design and testing are also given.
