Description

This paper describes a study on electroencephalogram (EEG)-based control. Discrimination methods for left/right direction thinking using brainwaves have been proposed. The main target of these studies were to develop control systems using the recognition result. Effects of measurement locations on human head on the recognition performance were not investigated. This paper employs Linear Discriminant Analysis (LDA) for this discrimination of human thinking. LDA makes us easy to investigate the relationships between the measurement positions and the recognition rates. The authors focus on alpha and beta waves which are called specific frequency range included in brainwaves, and we try to discriminate direction thinkings using the alpha and beta waves. Experimental results with four subjects show that average discrimination rate is approximately 70%. This paper also shows a preliminary investigation of eective measurement positions for the thinking detection.
