基于脑电信号的注意力水平评价研究进展

Research progress on attention level evaluation based on electroencephalogram signals

注意力水平评价是指通过观察或实验测试的手段对人的注意力水平进行评价,其研究成果在教育教学、智能驾驶、医疗健康等领域有很大的应用价值。脑电信号凭借其客观可靠性和安全性成为分析和表达注意力水平的最重要技术手段之一。目前,鲜有综述文献对脑电信号在注意力水平评价领域的应用进行全面的梳理总结。为此,本文首先概述了注意力水平评价的研究进展;然后重点剖析了脑电信号注意力水平评价的重要方法,包括数据预处理、特征提取与选择、注意力水平评价方法等;最后讨论了脑电信号注意力水平评价领域当前发展的不足,并对未来发展趋势进行展望,为相关领域的研究工作者提供参考。

Attention level evaluation refers to the evaluation of people's attention level through observation or experimental testing,and its research results have great application value in education and teaching,intelligent driving,medical health and other fields.With its objective reliability and security,electroencephalogram signals have become one of the most important technical means to analyze and express attention level.At present,there is little review literature that comprehensively summarize the application of electroencephalogram signals in the field of attention evaluation.To this end,this paper first summarizes the research progress on attention evaluation;then the important methods for electroencephalogram attention evaluation are analyzed,including data preprocessing,feature extraction and selection,attention evaluation methods,etc.;finally,the shortcomings of the current development in the field of electroencephalogram attention evaluation are discussed,and the future development trend is prospected,to provide research references for researchers in related fields.
