Spatio-temporal analysis of error-related brain activity in active and passive brain-computer interfaces. 主动和被动脑机接口中与错误相关的脑活动的时空分析。
IF 2.1 Q2 Engineering Pub Date : 2019-01-01 Epub Date: 2019-11-19 DOI: 10.1080/2326263x.2019.1671040

Electroencephalography (EEG)-based brain-computer interface (BCI) systems infer brain signals recorded via EEG without using common neuromuscular pathways. User brain response to BCI error is a contributor to non-stationarity of the EEG signal and poses challenges in developing reliable active BCI control. Many passive BCI implementations, on the other hand, have the detection of error-related brain activity as their primary goal. Therefore, reliable detection of this signal is crucial in both active and passive BCIs. In this work, we propose CREST: a novel covariance-based method that uses Riemannian and Euclidean geometry and combines spatial and temporal aspects of the feedback-related brain activity in response to BCI error. We evaluate our proposed method with two datasets: an active BCI for 1-D cursor control using motor imagery and a passive BCI for 2-D cursor control. We show significant improvement across participants in both datasets compared to existing methods.

基于脑电图(EEG)的脑机接口(BCI)系统在不使用常见神经肌肉通路的情况下推断脑电图记录的脑信号。用户大脑对脑机接口误差的反应是脑电信号非平稳性的一个因素,对开发可靠的脑机接口主动控制提出了挑战。另一方面,许多被动脑机接口实现将检测与错误相关的大脑活动作为其主要目标。因此,该信号的可靠检测在主动式和被动式脑机接口中都至关重要。在这项工作中,我们提出了CREST:一种新的基于协方差的方法,该方法使用黎曼和欧几里得几何,并结合了脑机接口误差响应中反馈相关的大脑活动的空间和时间方面。我们用两个数据集来评估我们提出的方法:一个使用运动图像进行一维光标控制的主动脑机接口和一个用于二维光标控制的被动脑机接口。与现有方法相比,我们在两个数据集的参与者中都显示出显着的改进。

Automated Artifact Rejection Algorithms Harm P3 Speller Brain-Computer Interface Performance. 自动伪影抑制算法损害P3拼写机脑机接口性能。
IF 2.1 Q2 Engineering Pub Date : 2019-01-01 Epub Date: 2020-03-02 DOI: 10.1080/2326263X.2020.1734401

Brain-Computer Interfaces (BCIs) have been used to restore communication and control to people with severe paralysis. However, non-invasive BCIs based on electroencephalogram (EEG) are particularly vulnerable to noise artifacts. These artifacts, including electro-oculogram (EOG), can be orders of magnitude larger than the signal to be detected. Many automated methods have been proposed to remove EOG and other artifacts from EEG recordings, most based on blind source separation. This work presents a performance comparison of ten different automated artifact removal methods. Unfortunately, all tested methods substantially and significantly reduced P3 Speller BCI performance, and all methods were more likely to reduce performance than increase it. The least harmful methods were titled SOBI, JADER, and EFICA, but even these methods caused an average of approximately ten percentage points drop in BCI accuracy. Possible mechanistic causes for this empirical performance deduction are proposed.

脑机接口(bci)已被用于恢复严重瘫痪患者的沟通和控制能力。然而,基于脑电图(EEG)的无创脑机接口特别容易受到噪声伪影的影响。这些伪影,包括眼电图(EOG),可能比要检测的信号大几个数量级。已经提出了许多自动化的方法来从EEG记录中去除EOG和其他伪影,大多数是基于盲源分离。这项工作提出了十种不同的自动工件去除方法的性能比较。不幸的是,所有被测试的方法都大大降低了P3 Speller的BCI性能,而且所有方法都更有可能降低而不是提高性能。危害最小的方法是SOBI、JADER和EFICA,但即使是这些方法也会导致BCI准确率平均下降约10个百分点。提出了这种经验绩效演绎的可能机制原因。

The Seventh International Brain-Computer Interface (BCI) Meeting was held May 21-25th, 2018 at the Asilomar Conference Grounds, Pacific Grove, California, United States. The interactive nature of this conference was embodied by 25 workshops covering topics in BCI (also called brain-machine interface) research. Workshops covered foundational topics such as hardware development and signal analysis algorithms, new and imaginative topics such as BCI for virtual reality and multi-brain BCIs, and translational topics such as clinical applications and ethical assumptions of BCI development. BCI research is expanding in the diversity of applications and populations for whom those applications are being developed. BCI applications are moving toward clinical readiness as researchers struggle with the practical considerations to make sure that BCI translational efforts will be successful. This paper summarizes each workshop, providing an overview of the topic of discussion, references for additional information, and identifying future issues for research and development that resulted from the interactions and discussion at the workshop.

第七届国际脑机接口(BCI)会议于2018年5月21日至25日在美国加利福尼亚州太平洋格罗夫的阿西洛马会议场地举行。本次会议的互动性体现在25个涵盖BCI(也称脑机接口)研究主题的研讨会上。研讨会涵盖了硬件开发和信号分析算法等基础性主题、虚拟现实生物识别和多脑生物识别等新颖而富有想象力的主题,以及临床应用和生物识别开发的伦理假设等转化性主题。BCI研究在应用和应用人群的多样性方面不断扩展。随着研究人员努力解决实际问题以确保 BCI 转化工作取得成功,BCI 应用正朝着临床准备就绪的方向发展。本文对每场研讨会进行了总结,概述了讨论主题,提供了更多信息参考,并指出了研讨会上的互动和讨论所产生的未来研发问题。

Trends in research participant categories and descriptions in abstracts from the International BCI Meeting series, 1999 to 2016. 1999年至2016年国际BCI会议系列摘要中的研究参与者类别和描述趋势。
IF 1.8 Q3 ENGINEERING, BIOMEDICAL Pub Date : 2019-01-01 Epub Date: 2019-08-01 DOI: 10.1080/2326263x.2019.1643203

Much brain-computer interface (BCI) research is intended to benefit people with disabilities (PWD), but inclusion of these individuals as study participants remains relatively rare. When participants with disabilities are included, they are described with a range of clinical and non-clinical terms with varying degrees of specificity, often leading to difficulty in interpreting or replicating results. This study examined trends in inclusion and description of study participants with disabilities across six International BCI Meetings from 1999 to 2016. Abstracts from each Meeting were analyzed by two trained independent reviewers. Results suggested a decline in participation by PWD across Meetings until the 2016 Meeting. Increased diagnostic specificity was noted at the 2013 and 2016 Meetings. Fifty-eight percent of the abstracts identified PWD as being the target beneficiaries of BCI research, though only twenty-two percent included participants with disabilities, suggesting evidence of a persistent translational gap. Participants with disabilities were most commonly described as having physical and/or communication impairments compared to impairments in other areas. Implementing participatory action research principles and user-centered design strategies continues to be necessary within BCI research to bridge the translational gap and facilitate use of BCI systems within functional environments for PWD.

许多脑机接口(BCI)研究旨在造福残障人士(PWD),但将这些人纳入研究对象的情况仍然相对罕见。即使纳入了残障人士,也会用一系列临床和非临床术语对其进行描述,具体程度不一,往往导致难以解释或复制结果。本研究考察了1999年至2016年六次国际BCI会议中纳入和描述残疾研究参与者的趋势。每次会议的论文摘要均由两名经过培训的独立审稿人进行分析。结果表明,在2016年会议之前,残疾人在各次会议中的参与度有所下降。2013年和2016年会议的诊断特异性有所提高。58%的摘要指出残疾人是BCI研究的目标受益人,但只有22%的摘要包括残疾参与者,这表明存在持续的转化差距。与其他方面的障碍相比,残疾参与者最常被描述为有身体和/或交流障碍。在BCI研究中实施参与式行动研究原则和以用户为中心的设计策略仍然是必要的,以弥合转化差距并促进残疾人在功能环境中使用BCI系统。

ABSTRACTThis study sought to understand the perceptions of special education staff and caregivers (n = 6) who took part in a brain-computer interface (BCI) technology trial for individuals with severe cerebral palsy. Participants were interviewed post-trials regarding the different BCI components. The transcripts were coded and analyzed using thematic analysis. Results showed that BCIs are not suitable for independent use outside of clinical/laboratory settings. The hardware needs to be configurable, comfortable and accommodate physical support needs. The training approach needs to be less cognitively demanding, motivating and support personalized mental tasks. For BCIs to transition into the real world, there should be adequate technological support, improved reliability, and a systemic assessment of how the technology will fit into the lives of end users. Participants emphasized the on-going need to involve users and individuals who support them, to create a system that truly meets the needs of the users.
摘要本研究旨在了解参与重度脑瘫患者脑机接口(BCI)技术试验的特殊教育人员和护理人员(n = 6)的看法。参与者在试验后接受了关于不同脑机接口成分的访谈。使用主题分析对转录本进行编码和分析。结果显示,脑机接口不适合在临床/实验室环境之外独立使用。硬件需要是可配置的,舒适的,并适应物理支持需求。训练方法需要减少对认知的要求,激励和支持个性化的心理任务。为了使bci过渡到现实世界,应该有足够的技术支持,提高可靠性,并对技术如何适应最终用户的生活进行系统评估。与会者强调,持续需要用户和支持他们的个人参与,以建立一个真正满足用户需要的系统。

Participants were interviewed post-trials regarding the different BCI components. The transcripts were coded and analyzed using thematic analysis. Results showed that BCIs are not suitable for independent use outside of clinical/laboratory settings. The hardware needs to be configurable, comfortable and accommodate physical support needs. The training approach needs to be less cognitively demanding, motivating and support personalized mental tasks. For BCIs to transition into the real world, there should be adequate technological support, improved reliability, and a systemic assessment of how the technology will fit into the lives of end users.
