摘要：

目的為在理想環(huán)境下研究腦機(jī)交互（brain computer interface, BCI）系統(tǒng)，并為系統(tǒng)的實(shí)際應(yīng)用開發(fā)做鋪墊，本文基于Java3D設(shè)計(jì)了腦機(jī)交互應(yīng)用系統(tǒng)。方法 EEG信號(hào)經(jīng)分析處理后轉(zhuǎn)換成的實(shí)時(shí)控制命令，通過TCP/IP協(xié)議傳給Java3D應(yīng)用系統(tǒng)，實(shí)時(shí)控制虛擬小車運(yùn)動(dòng)。該應(yīng)用系統(tǒng)的設(shè)計(jì)分三步：首先搭建虛擬場(chǎng)景，包括對(duì)場(chǎng)景模型的建立以及對(duì)場(chǎng)景的布局設(shè)計(jì)；其次設(shè)計(jì)虛擬小車的運(yùn)動(dòng)，實(shí)現(xiàn)小車前進(jìn)和旋轉(zhuǎn)的連續(xù)運(yùn)動(dòng)；最后對(duì)場(chǎng)景中的模型配置進(jìn)行碰撞檢測(cè)，用基于運(yùn)動(dòng)想象的EEG分析結(jié)果實(shí)時(shí)控制小車運(yùn)動(dòng)，檢驗(yàn)本系統(tǒng)的功能。結(jié)果 EEG信號(hào)可以實(shí)時(shí)控制虛擬小車進(jìn)行連續(xù)運(yùn)動(dòng)，且碰撞檢測(cè)功能正常。結(jié)論研究結(jié)果初步證明該應(yīng)用系統(tǒng)的可行性，為BCI應(yīng)用系統(tǒng)的設(shè)計(jì)提供了新穎思路并奠定了良好基礎(chǔ)。

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.
