Method for analyzing factors influencing emotion changes and electronic equipment

Abstract

The invention provides a method for analyzing factors influencing emotion changes and electronic equipment. The method comprises the following steps: collecting electrocardiogram signals, breathing signals and acceleration signals of a subject at different states in preset time, and averaging the breathing signals at different states; utilizing a maximum value of the acceleration signals repeatedly collected at different states as an acceleration threshold value; and acquiring a breathing reference value, the acceleration threshold value and an electrocardiogram signal base line. The method further comprises an analysis step as follows: synchronously collecting the electrocardiogram signals, the breathing signals, the acceleration signals and environmental signals, and carrying out comparison on the collected acceleration signals and the acceleration threshold value; when the acceleration signals are larger than the acceleration threshold value, demarcating the collected acceleration signals, and carrying out Kalman filtering by virtue of the sum of three axes of the demarcated acceleration signals, so as to filter motion interferences; acquiring breathing change through comparisonbetween the breathing signals and the breathing reference value; analyzing the electrocardiogram signals in which the motion interferences are filtered, so as to obtain an SDNN index and a pressure index; and acquiring the factors influencing the emotion changes according to the environmental signals, skin temperature signals, motion states and the pressure index.

Description

technical field [0001] The invention relates to the technical field of psychological evaluation, in particular to an analysis method for factors affecting emotional changes and electronic equipment. Background technique [0002] At present, there are many devices on the market for the measurement of physiological indicators, such as ECG sensors, skin temperature sensors, etc., but these different types of sensors require many electrodes to be attached to the human body, and will limit the state of the person. During the electrocardiogram, the subject needs to lie down to obtain a good signal; whether it is an infrared or contact skin temperature sensor, the measurement of skin temperature by forehead measurement is easily affected by the surrounding environment temperature. [0003] At the same time, when it is necessary to analyze the cause of the change in the psychological state of the subject, it is necessary to place a variety of different test equipment on the subject ...

[0002] At present, there are many devices on the market for the measurement of physiological indicators, such as ECG sensors, skin temperature sensors, etc., but these different types of sensors require many electrodes to be attached to the human body, and will limit the state of the person. During the electrocardiogram, the subject needs to lie down to obtain a good signal; whether it is an infrared or contact skin temperature sensor, the measurement of the skin temperature by forehead measurement is easily affected by the surrounding environment temperature.

[0003] At the same time, when it is necessary to analyze the reasons for the changes in the psychological state of the subjects, it is necessary to place a variety of different test equipment on the subjects at the same time, which makes the test process very cumbersome

Moreover, it is impossible to consider the impact of exercise conditions on people, which increases the error of the analysis, which leads to deviations in the analysis of the psychological state of the subjects
