Brain-computer interface (BCI) is a revolutionizing human-computer interaction with potential applications in both medical and non-medical fields, emerging as a cutting-edge and trending research direction. Increasing numbers of groups are engaging in BCI research and development. However, in recent years, there has been some confusion regarding BCI, including misleading and hyped propaganda about BCI, and even non-BCI technologies being labeled as BCI. Therefore, a clear definition and a definite scope for BCI are thoroughly considered and discussed in the paper, based on the existing definitions of BCI, including the six key or essential components of BCI. In the review, different from previous definitions of BCI, BCI paradigms and neural coding are explicitly included in the clear definition of BCI provided, and the BCI user (the brain) is clearly identified as a key component of the BCI system. Different people may have different viewpoints on the definition and scope of BCI, as well as some related issues, which are discussed in the article. This review argues that a clear definition and definite scope of BCI will benefit future research and commercial applications. It is hoped that this review will reduce some of the confusion surrounding BCI and promote sustainable development in this field.
脑机接口（BCI）是一种变革性的人机交互方式，在医学和非医学领域都有潜在应用，正成为一个前沿且热门的研究方向。越来越多的团队参与到BCI的研发中。然而，近年来，关于BCI出现了一些混乱，包括对BCI的误导性和炒作性宣传，甚至将非BCI技术贴上BCI的标签。因此，本文基于BCI的现有定义，包括BCI的六个关键或基本组成部分，对BCI的明确定义及确定范围进行了全面的思考和讨论。在这篇综述中，与以往BCI的定义不同，所给出的BCI明确定义明确纳入了BCI范式和神经编码，并且明确将BCI用户（大脑）确定为BCI系统的关键组成部分。不同的人对BCI的定义、范围以及一些相关问题可能有不同的观点，本文对此进行了讨论。这篇综述认为，BCI的明确定义及确定范围将有利于未来的研究和商业应用。希望这篇综述能减少围绕BCI的一些混乱，并促进该领域的可持续发展。
