Steady-State VEPs in CAVE for Walking Around the Virtual World
Conference paper
Abstract
The human brain activities of steady-state visual evoked potentials, induced by a virtual panorama and two objects, were recorded for two subjects in immersive virtual environment. The linear discriminant analysis with single trial EEG data for 1.0 seconds resulted in 74.2 % of averaged recognition rate in inferring three gaze directions. The possibility of online interaction with 3D images in CAVE will be addressed for walking application or remote control of a robotic camera.
