Problems solved by technology

In addition, in terms of the accuracy of emotion description, in the field of psychology and computer emotion computing, although there are related technical foundations for emotion recognition and calculation of biosignals, including EEG, ECG, respiration rate, blood oxygen saturation, body surface Single or multi-modal emotion recognition models such as temperature, but the above-mentioned models are mainly used to identify some typical emotional types, such as: sadness, happiness, disappointment, anger, etc. These emotional states are usually stimulated by stimuli that contain storylines. Obviously, , the above typical emotional types are not sufficient to describe the natural emotional states of adolescents in different built environments
[0006] In addition, in terms of the selection of stimulus sources, the existing methods are relatively simple, most of which include the stimulus source of the story; and do not distinguish the content of the stimulus object and the source itself, there is a large chance in the actual operation, and the stimulus effect is not good. Satisfactory

Embodiment Construction

[0051] see Figure 1-8 , EEG-based emotional perception system for teenagers' environmental psychology, including EEG signal acquisition module, EEG signal preprocessing module, EEG signal feature extraction module and emotion perception module; based on the built environment that teenagers often contact, participate in or are passionate about As the source of visual stimulation, the subjects were teenagers;

[0052] The EEG signal acquisition module is used to collect the original 32-lead EEG signals of the subject through the recording electrodes and the reference electrodes, and send the collected original EEG signals to the EEG signal preprocessing module; The 32-lead EEG signal was acquired by using the international 10-20 system electrode placement method, and each electrode corresponds to one EEG signal. The electrode placement method of the international 10-20 system adopted in the present invention: place 30 recording electrodes and 2 reference electrodes, and the la...

Abstract

The invention discloses a system and a method for sensing emotion of juvenile environmental psychology based on electroencephalogram, and a method for selecting simulation samples. The system comprises an electroencephalogram signal acquisition module, an electroencephalogram signal preprocessing module, an electroencephalogram signal feature extraction module, an emotion sensing module and the like; and a built environment serves as a visual simulation source, wherein juveniles often contact with, participate in or are crazy about the built environment. The emotion sensing method comprises the steps of selecting the visual simulation source, acquiring the electroencephalogram signal, preprocessing the electroencephalogram signal, extracting electroencephalogram signal features, training a model, determining emotion intensity and the like. According to the method for selecting the simulation samples, arousal dimensionality and valence dimensionality are divided according to 5 emotion intensities, and rectangular select boxes are determined non-equidistantly according to the actual selected condition of the samples and the distribution state of the samples in a two-dimensional space. The emotion sensing system, the emotion sensing method and the method for selecting the simulation samples have the advantages of high emotion sensing ability, object extending ability and the like, and have high application values in environmental psychology research.

Description

technical field [0001] The invention relates to an EEG-based emotional perception system and method for adolescent environmental psychology, and a stimulus sample selection method. Background technique [0002] According to statistics, the number of minors under the age of 18 in my country is as high as 367 million. According to conservative estimates, there are as many as 30 million people with various learning, emotional and behavioral disabilities. In recent years, the incidence of psychological problems among Chinese adolescents has shown an obvious upward trend in recent years, and the incidence of children's psychological and behavioral problems is as high as 14% to 17%. Among them, emotional problems (such as anxiety, depression, etc.) are one of the common psychological problems, with a high incidence rate and wide spread, and affect the individual's behavior and psychosocial function. The World Health Organization (WHO) predicts that children and adolescents with ...
