Embodiment Construction

[0030] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments, but the embodiments of the present invention are not limited thereto.

[0031] Heart rate refers to the number of heartbeats per minute in a normal person's quiet state, also called resting heart rate, generally 60-100 beats per minute. Electrocardiogram (ECG) is a synthesis of action potentials generated by cardiomyocytes when the human heart pulses. If two electrodes are placed on the body surface, changes in ECG can be recorded through the potential difference between two points on the body surface to form a continuous curve, which is called an electrocardiogram. Skin electricity is an emotional physiological indicator, which represents the change of skin conduction when the body is stimulated.

[0032] Physiological signals such as ECG, heart rate, and skin electricity contain the content of emotional changes. Changes in emotion can be disti...

Abstract

The invention provides an emotion recognition system and method based on a wearable bracelet. The system comprises a physiological signal acquisition module, a physiological signal preprocessing module, a physiological signal feature extraction module, an emotion classification module and a comprehensive evaluation module; the physiological signal acquisition module is used for acquiring three kinds of physiological data of electrocardiograph, heart rate and skin electricity of a wearer; the physiological signal preprocessing module is used for carrying out data segmentation and denoising on the three kinds of physiological data and then transmitting the physiological data to the physiological signal feature extraction module; the physiological signal feature extraction module is used forcarrying out feature extraction on the three kinds of physiological data; the emotion classification module is used for carrying out emotion recognition on the three kinds of physiological data and outputting three emotion states; the comprehensive evaluation module adopts a weight-based voting decision rule, voting decision is carried out on the three emotional states, a current emotional state label of the wearable bracelet wearer is determined comprehensively, and a recognition result is obtained. According to the system, the cognitive and management capability of the wearer on the emotionof the wearer is improved, and a healthier psychological state can be possessed.

Description

technical field [0001] The invention relates to the field of wearable devices, in particular to an emotion recognition system and method based on a wearable bracelet. Background technique [0002] In recent years, mobile Internet technology has achieved rapid development, and wearable devices have played a very important role in people's lives, and have gradually become more popular products in consumer electronics. It helps people develop a healthy lifestyle and plan their work and life more reasonably. Wearable electronic devices are favored by consumers and developers for their advantages of easy portability, accurate measurement, and strong expansion capabilities. In today's society, people are facing increasing work and life pressure. Long-term pressure has a serious impact on people's emotions. Negative emotions can easily lead to depression, heart disease, high blood pressure, endocrine disorders and other health problems. Therefore, early detection of potential emo...
