Abstract

The invention discloses an attention evaluation method and an attention evaluation system. The attention evaluation method comprises the following steps: acquiring electroencephalogram (EEG), an electrocardiosignal and behavioral data; converting the EEG from a time domain to a frequency domain, and extracting an EEG feature vector; performing cepstrum processing on the electrocardiosignal, and extracting an electrocardiosignal feature vector; processing the behavior data, and extracting a behavior feature vector; and processing the EEG feature vector, electrocardiosignal feature vector and the behavior feature vector by adopting a PCVM (Production Centered Virtual Manufacturing) probability classification algorithm, thereby obtaining the evaluation result. With the adoption of the technical scheme, the EEG, electrocardiosignal and behavioral data of a testee can be comprehensively processed and analyzed, the comprehensive feature vectors are subjected to classified counting, the problem that the attention evaluation accuracy cannot be improved is solved, and accurate and stable attention level prediction results of the testee can be obtained.

Description

technical field [0001] The invention relates to the technical field of high-speed rail, in particular to an attention evaluation method and system. Background technique [0002] At present, there are more and more methods for evaluating the level of attention. Among them, one method is mainly to collect, process and analyze the EEG signal of the subject, and then extract the characteristics of the EEG signal from the time domain and frequency domain; The tester's electrocardiographic signal (ECG) is collected, processed and analyzed, and then the characteristic indicators related to the cardiac cycle are extracted from it. [0003] All of the above methods only collect and analyze the subjects' electroencephalogram (EEG) or electrocardiogram (ECG) separately, and do not effectively combine the two parameters for analysis. Therefore, the accuracy of existing evaluation methods needs to be improved. Contents of the invention [0004] The main purpose of the embodiments of...
