Design of an EEG-based brain-computer interface (BCI) from standard components running in real-time under Windows.

摘要: An EEG-based brain-computer interface (BCI) is a direct connection between the human brain and computer. Such communication system needed by patients with severe motor impairments (e. g. late stage of Amyotrohpic Lateral Sclerosis) has to operate in real-time. This paper describes selection appropriate components construct such BCI focuses also on suitable programming language operating system. The multichannel runs under Windows 95, equipped real-time Kernel expansion obtain reasonable operations standard PC. Matlab controls data acquisition presentation experimental paradigm, while Simulink used calculate recursive least square (RLS) algorithm that current state EEG First results new low-cost show accuracy differentiating imagination left right hand movement around 95 %.
