Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0021] Such as figure 1 As shown, the comprehensive quantification method of physiological arousal of the present invention includes collection of heart rate, calculation of long-range fluctuation coefficient of heart rate, calculation of local Hurst index of heart rate, calculation of average heart rate and fusion of various heart rate arousal indicators. If tachycardia causes the long-range fluctuation arousal index to fail, only the mean value index and the local Hurst exponent range index are fused; otherwise, all three indexes are fused. The quantified physiological arousal is obtained by fusing various heart rate arousal indicators.

[0022] The heart rate is calculated from the R wave location and the RR interval of the electrocardiographic signal, and the electrocardiographic signal is obtained directly through a physiological acquisition de...

Abstract

A physical arousal degree comprehensive quantifying method based on heart rate index includes heart rate collecting, calculation of heart rate long-range fluctuation coefficient, calculation of heart rate local Hurst index and calculation of heat rate mean value. High heart rate mean value can purely come from physical arousal caused by body movement. The small local Hurst index value range generally comes from stress physical arousal. The heart rate long-range fluctuation coefficient can stably balance the physical arousal degree in the normal range (smaller than 90 / min). By means of fusion of the above three indexes, the physical arousal comprehensive quantifying index allowing continuous valuing between peace to high arousal is acquired.

Description

technical field [0001] The invention relates to a comprehensive quantification method of physiological arousal degree based on heart rate index. Background technique [0002] Accurate quantification of physiological arousal can better reflect the degree of emotional excitement or tension, and has a good emotional indicator function. However, the current theoretical research and technical invention of emotion recognition for physiological signals is mainly to extract a large number of physiological signal parameters from a variety of physiological signals, and to classify and identify specific types of emotions, ignoring that various emotions are accompanied by a certain degree of physiological arousal. , and also ignores the quantification of physiological arousal. [0003] Therefore, the problem to be solved by the present invention is: to break the traditional method of emotion recognition from the perspective of specific emotion types, to provide a new physiological arou...
