Development of a BCI Simulated Application System Based on Unity3D

This paper develops a BCI simulated application system based on Unity3D, called going to the cinema. Firstly, a 3D car model and some scene models built in 3ds Max are imported into Unity3D. Then, in Unity3D, the virtual reality scene layout is designed with its own and imported models. The audio effects and collision detection are added to enhance realistic immersion. After that, the behaviors of the 3D car are defined. The communication and timer functions are configured. Finally, the system can receive the commands through the TCP/IP protocol to control the 3D car movement to go to the destination-cinema. The simulation results show that the system is feasible and has good performance. The designed system can be used as not only a simulated application system, but also a feedback training system providing effective feedback of vision and hearing, which can lay a foundation for BCI application and feedback.
