摘要:
近年来,一类被称之为脑控的新型控制系统发展迅速, 这是一种基于脑--机接口(Brain-computer interface, BCI)的人机融合控制系统, 也是一种基于人的意念和思维的控制系统. 脑控系统已被成功应用于残疾人的生活辅助、中风病人和损伤肢体的康复训练、 操作员状态的实时监控、游戏娱乐和智能家居等广泛的领域. 本文在简要介绍了脑控的研究背景、基本原理、系统结构和发展概况的基础上, 着重对脑电信号(Electroencephalogram, EEG)模式、控制信号转换算法和应用系统研究等主要问题的研究现状, 进行了较为详细的论述和分析, 并探讨了进一步研究的方向和思路. 最后对脑控的未来发展方向和应用前景进行了分析和展望.
Abstract:
Recently, a new system called brain control system has been developed rapidly. Brain control system is a human-computer integration control system based on brain-computer interface (BCI), which relies on human's ideas and thinking. Brain control system has been successfully applied in wide fields, assisting disabled patients daily life, training patients with stroke or limb injury, monitoring the status of human operator, as well as entertainment and smart house etc. In this paper, the background, basic principle, system structure and developments are firstly introduced briefly. The current research status focusing on the problems of electroencephalogram (EEG) signal pattern, control signal transfer algorithm and system application is summarized and analyzed in detail. The further research direction and thoughts are discussed. Finally, the future development of brain control is analyzed and prospects are given.
