Problems solved by technology

[0004] In order to overcome the problem that the previous studies only divided the emotional state into two states of calm and excited, and did not consider individual differences, the present invention discloses an emotion detection method based on the change of human skin resistance. Change this phenomenon to qualitatively and quantitatively analyze the degree of human emotional changes, so as to use it

Embodiment 1

[0088] Figure 10 The frequency of deep breathing of the human body is once every 2 seconds, and the time is 20s. The detected resistance / emotional state value-time curve; Figure 11 The frequency of human deep breathing is 2 seconds, and the time is 60s. The detected resistance / emotional state value-time curve; the comparison shows that the longer the deep breathing time, the longer the duration of excitement, and the higher the detected emotional state value.

Embodiment 2

[0090] Figure 12 The frequency of deep breathing of the human body is once every 2 seconds, and the time is 60s. The detected resistance / emotional state value-time curve; Figure 13 The frequency of human deep breathing is once every 10 seconds, and the time is 60s. The detected resistance / emotional state value-time curve; the comparison shows that the faster the deep breathing frequency, the higher the emotional state value.

[0091] Experimental data shows that the method of the present invention can more finely divide the calm state and the excited state, and express the different degrees of excitement of the human body.

Abstract

The invention discloses an emotion detection method and system based on human skin resistance changes. The method includes parameter initialization, acquisition of human body resistance data, data analysis, and emotional state values feedback for a user. The analysis comprises preprocessing and threshold analysis, slope analysis, slope and duration combined analysis, and slope, duration and threshold combined analysis. The system comprises a medical pole piece, a bridge resistance / conductivity measurement circuit, an amplifying circuit, an A / D conversion circuit, a CPU and a man-machine interface. According to the method and system, a self-adaptive algorithm is adopted, emotions is reflected through the resistance, slope and state duration changes, the problem of individual differences can be overcome, and the excitability of testers can be reflected more accurately.

Description

technical field [0001] The invention relates to an emotion detection method based on changes in human skin resistance. Background technique [0002] When organisms feel external stimuli and emotional agitation, their skin resistance increases due to the potential difference between the two points, resulting in a decrease in the resistance between the two points of the skin. This phenomenon is called physiological electrical reflex. People's research on this phenomenon is not very deep. At present, the more authoritative explanation is that the change of human skin resistance is related to the activity of sweat glands. When emotional, more sweat is secreted, and there are a lot of electrolytes in the sweat, which leads to changes in the surface resistance of the human skin. [0003] Many researchers have also analyzed the relationship between emotion and resistance, but they are devoted to why emotional fluctuations affect the change of human skin resistance. They only use t...
