Multi-class Classification of EEG Activities to Explore a Virtual City

-Linear Discriminant Analysis-

Abstract

The electroencephalograms were measured to explore a virtual city only via human brain activities.By applying virtual reality technology,the visual evoked potentials,induced by virtual panorama and by virtualsquares,were recorded with three electrodes over the visual cortex.The linear discriminant analysis made about74.2 % of averaged recognition rate in inferring three gaze directions for two subjects.The possibility will be pre-sented to interact with a computer graphics according to the estimated gaze directions.
