Abstract This thesis is focusing on research in to develop the brain computer interfaces somatosensory assistive virtual reality (VR) control algorithm for achieving trajec-tory tracking purpose using the brainwave capture instrument. First, the brain-computer interface uses signals recorded from the brain waves. The virtual reality is constructed by a specified environment in the Cartisian space where a ball is setup up to move around on the ground driven by brainwave.By using the fast Fourier transform (FFT), we can construct the best upper and lower desired brain thinkingcontrol trajectory. Then, the brian computer feedback control is designed through the measurement of the ball position and velocity, and various information Biblot control (Brian control) to stabilize the closed-loop ball control virtual reality sys-tem and achieve the trajectory tracking purpose.The proposed control algorithm is written by Visual C#. Finally, simulations are used to show the effectiveness of the proposed by converting the ball up/down or left/right on the VR system by way of a brain wave instrument.
