| 摘 要： | 脑机接口是一种不依赖于外周神经和肌肉等常规输出通道的信息交流系统。它可为神经肌肉障碍患者提供一条与外界沟通的途径,在虚拟现实、游戏娱乐以及航空等领域也具有重要的潜在价值。近年来,脑机接口的发展非常迅速,尤其对脑电信号的特征提取和特征转换等的研究较多。其中,稳态视觉诱发电位(SSVEP)和P300等皮层诱发电位信号因易于处理且不需要长时间训练而被广泛应用于脑机接口。本文总结了基于稳态视觉诱发电位(SSVEP)和基于P300脑机接口的研究进展,重点分析了脑机接口的实验范式以及目前相关研究存在的困难。

| Abstract: | Brain-computer interface(BCI) was a communication system that did not depend on the brain's normal output pathways of the peripheral nerves and muscles.BCI provided a new communication channel for the patients with severe neuromuscular disorders,and also had potential values in virtual reality,entertainment and aviation.Recently,BCI developed rapidly,and its researches mostly concentrated on feature extraction and translation algorithm.Cortical evoked potentials such as steady-state visual evoked potential(... |
