基于脑电的无创脑机接口研究进展

A review of non-invasive electroencephalogram-based brain computer interfaces

脑机接口在脑与外部环境之间建立一种全新的不依赖于外周神经和肌肉的交流与控制通道,从而实现脑与外部设备的直接交互。脑电因具有非侵入式、易于使用及设备价格低廉等特点而被广泛应用于脑机接口。本文回顾了基于脑电的无创脑机接口的研究历史,从脑机接口的类型、应用及面临的挑战3个方面综述了脑机接口的研究现状,并展望了脑机接口的未来发展前景。

The brain computer interface（BCI） is a new communication and control channel between the brain and the external world that does not depend on the peripheral nerves and muscles, with a direct interaction between the brain and the external devices. Due to the advantages such as the noninvasiveness, the ease-of-use, and the low cost, the electroencephalogram（EEG） is the most popular method for current BCIs. This paper first reviews the history of the EEG-based non-invasive BCIs. Then, the focus is placed on the state-of-art of researches in three main aspects, namely the taxonomy of the current BCIs, the applications of the BCIs, and the challenges in developing the BCIs. Finally, a summary of future developments of the EEG-based BCI technology is given.
