Brain-computer interface (BCI) is a revolutionizing human-computer interaction, which has potential applications for specific individuals or groups in specific scenarios. Extensive research has been conducted on the principles and implementation methods of BCI, and efforts are currently being made to bridge the gap from research to real-world applications. However, there are inaccurate or erroneous conceptions about BCI among some members of the public, and certain media outlets, as well as some BCI researchers, developers, manufacturers, and regulators, propagate misleading or overhyped claims about BCI technology. Therefore, this article summarizes the several misconceptions and misleading propaganda about BCI, including BCI being capable of “mind-controlled,” “controlling brain,” “mind reading,” and the ability to “download” or “upload” information from or to the brain using BCI, among others. Finally, the limitations (shortcomings) and limits (boundaries) of BCI, as well as the necessity of conducting research aimed at countering BCI systems are discussed, and several suggestions are offered to reduce misconceptions and misleading claims about BCI.

关于脑机接口的若干不准确或错误的观念和误导性宣传

脑机接口（BCI）是一种革命性的人机交互方式，对于特定场景下的特定个体或群体具有潜在的应用前景。人们对BCI的原理和实现方法进行了广泛的研究，目前正在努力弥合研究与实际应用之间的差距。然而，一些公众对BCI存在不准确或错误的观念，某些媒体以及一些BCI研究人员、开发商、制造商和监管机构传播有关BCI技术的误导性或过度炒作的说法。因此，本文总结了关于BCI的几种误解和误导性宣传，包括BCI能够“意念控制”、“控制大脑”、“读心术”以及能够“下载”或“上传”信息。使用 BCI 等来控制大脑。最后，讨论了 BCI 的局限性（缺点）和局限性（边界），以及开展旨在对抗 BCI 系统的研究的必要性，并提出了一些建议，以减少对 BCI 的误解和误导性主张。
