基于脑电图(EEG)的脑机接口(BCI)系统推断通过EEG记录的大脑信号,而不使用常见的神经肌肉通路。用户大脑对BCI错误的反应是导致EEG信号非平稳性的一个因素,并对开发可靠的主动BCI控制提出了挑战。另一方面,许多被动BCI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和被动BCI中都是至关重要的。在这项工作中,我们提出了CREST:一种新的基于协方差的方法,使用黎曼几何和欧几里得几何,并结合空间和时间方面的反馈相关的脑活动,以响应BCI错误。我们评估我们提出的方法与两个数据集:1-D光标控制使用运动想象和2-D光标控制的被动BCI的主动BCI。与现有方法相比,我们在两个数据集中的参与者中显示出显着的改进。
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.
