Development of a BCI simulated application system based on DirectX

Abstract

This paper proposes a novel Brain Computer Interface (BCI) simulated application system based on DirectX. In the application system, a virtual car built by 3D Studio Max is imported into the DirectX, first. Then the transformation matrix is designed for the car to achieve the control of movement. Some objects are developed in virtual scenes for enhancing realistic immersion, such as the sky and obstacles. The virtual car can receive the control commands from Electroencephalography (EEG) signal processing system by the TCP/IP protocol. Finally, the virtual car can perform turning left, turning right, moving straight, and so on. The simulated results show that it is available to implement the real-time control by EEG signal. The designed system can not only be used as a simulated application but also be used as feedback for subjects. What is more, as no need for robotics and other hardware, the system is cost-effective, interesting, and ease of use. Potentially, the system can promote the research of BCI application and feedback.
