基于Java3D的脑机交互应用系统设计
Design of BCI application system based on Java3D
摘要
Abstract
Objective An application system based on Java3D in brain computer interfaces ( BCI ) is designed to study the BCI system in an ideal environment, and pave the way for the development of the practical applications. Methods The processed EEG signals are converted to the real-time control commands which may drivre the virtual car to move by TCP/IP. The system design contains three steps. Firstly, we set up a virtual scene, build models and make the layout of the scene. Secondly we design a virtual car which can move forward and rotate continuously. Thirdly, we design the collision detection with the models in the scene and apply EEG analysis based on imagination activities to control the car in real time in order to test the system function. Results The experimental results show that EEG signals can continuously drive the virtual car to move in real time, and the function of collision detection is normal. Conclusions The results preliminary prove the feasibility of the application system, present a good foundation and set an example for the design of BCI application system.关键词
