A BCI headset was coupled with a VR headset to generate a VR + BCI environment. The author developed a VR game in which the avatar\'s movement is controlled using the user\'s cortical responses with the help of a BCI headset. Specifically designed visual stimuli were used in the proposed system to elicit the strongest possible responses from the user\'s brain. The proposed system also includes an auditory feedback mechanism to facilitate precise avatar movement.
Conventional P300 BCI and SSVEP BCI were also used to control the movements of the avatar, and their performance metrics were compared to those of the proposed system. The results demonstrated that the hybrid SSVEP + P300 BCI system was superior to the other systems for controlling avatar movement.
方法:将BCI耳机与VR耳机耦合以生成VR+BCI环境。作者开发了一个VR游戏,在BCI耳机的帮助下,使用用户的皮层反应控制化身的移动。在所提出的系统中使用了专门设计的视觉刺激,以引起用户大脑的最强反应。所提出的系统还包括听觉反馈机制以促进精确的化身移动。
结论:常规P300BCI和SSVEPBCI也用于控制化身的运动,并将它们的性能指标与拟议系统的性能指标进行了比较。结果表明,混合SSVEPP300BCI系统在控制化身运动方面优于其他系统。
