Feasibility study for implementing brain computer interface using electroencephalograph

Abstract

The purpose of a Brain Computer Interface (BCI) consists of the development of an interface between a human and a computer to allow the control of a device only via brain signals. The conformance of the system and the individual brain patterns of the subject is the major concern while developing the interface. In this paper, we begin with the exploration of variety of brain sensing technologies for detecting the specific forms of brain activity used in HCI research and then analyzing the properties of the most prevalent technology used in HCI research – Electroencephalograph. We have then proceeded with our aim of conducting a feasibility study of this implementation idea and verified the same by clearly determining the requirements and setting up of the appropriate facilities for research. We have also described and discussed the experiments showing the differences in the brain wave patterns for proving the same.
