本发明公开一种基于SSVEP的注意力测评方法、训练方法以及脑机接口，通过显示测试图像刺激受试者的视觉，采集受试者的脑电波，提取所述脑电波中的SSVEP，使用SSVEP的幅值特征表征受试者的注意力程度。本发明的方法实现注意力程度的量化，提高了注意力程度评测的准确性和可用性；提高脑电信号能够反映的信息维度，提高脑机接口的可用性，拓宽脑机接口的运动控制功能。 An SSVEP-based attention evaluation method, a training method, and a brain-computer interface are provided. The vision of a subject (3) is stimulated by means of displaying test image(s) (2), the brain waves of the subject (3) are collected, the SSVEP in the brain waves is extracted, and the amplitude features of the SSVEP are used to represent the degree of attention of the subject (3). The present method achieves quantification of the degree of attention and increases the accuracy and usability of attention evaluation, increases the dimension of information that EEG signals can reflect, increases the usability of the brain-computer interface, and widens the motion control function of the brain-computer interface.
