Abstract :
Brain activities in a standing posture were studied in immersing virtual environments. Electroencephalographic oscillations induced by two flickering virtual buttons were recorded for one subject. The flickering frequencies were set to be 6.9 and 4.8 Hz. Even in standing, clear steady-state visual evoked potentials were observed. Linear discriminant analysis with the single trial brain activities for 2 seconds yielded 74.9% of the average classification performance in sitting and 80.7% in standing in inferring three eye-gaze directions. The results in this study contribute to reduce both mental and physical stress of the users of brain-computer interfaces.
