[Applications, industrial transformation and commercial value of brain-computer interface technology]

Brain-computer interface (BCI) is a revolutionary human-computer interaction technology, which includes both BCI that can output instructions directly from the brain to external devices or machines without relying on the peripheral nerve and muscle system, and BCI that bypasses the peripheral nerve and muscle system and inputs electrical, magnetic, acoustic and optical stimuli or neural feedback directly to the brain from external devices or machines. With the development of BCI technology, it has potential application not only in medical field, but also in non-medical fields, such as education, military, finance, entertainment, smart home and so on. At present, there is little literature on the relevant application of BCI technology, the current situation of BCI industrialization at home and abroad and its commercial value. Therefore, this paper expounds and discusses the above contents, which are expected to provide valuable information for the public and organizations, BCI researchers, BCI industry translators and salespeople, and improve the cognitive level of BCI technology, further promote the application and industrial transformation of BCI technology and enhance the commercial value of BCI, so as to serve mankind better.脑机接口（BCI）是一种变革性的人机交互技术，其中既有不依赖外周神经和肌肉系统即可从大脑直接向外部设备或机器输出指令的BCI，也包括绕过外周神经和肌肉系统从外部设备或机器直接向大脑输入电、磁、声和光等刺激或神经反馈的BCI。随着BCI技术的发展，其不仅在医学领域具有潜在的应用，而且在非医学领域，如教育、军事、金融、娱乐、智能家居等方面也具有应用前景。目前，鲜有对BCI技术的相关应用、国内外BCI产业化现状以及其商业价值进行详细论述的文献，为此本文对上述内容展开阐述和讨论，可望为社会公众及组织、BCI研究人员、BCI产业转化者和销售人员提供有价值的信息，提高对BCI技术的认知水平，进一步促进BCI技术的应用和产业转化，提升BCI的商业价值，以便更好地为人类服务。.
