A mental state assessment system based on a holographic projection technology and a working method thereof

Abstract

The invention provides a mental state assessment system based on a holographic projection technology. The mental state assessment system is characterized by comprising holographic projection equipmentfor holographic projection of a scene source file in a holographic projection scene library; The audio playing module is used for playing an audio source file in the audio library; The physiologicalsignal acquisition module is used for acquiring physiological signals of a tested person and sending the physiological signals outwards; And the mental state assessment module is used for receiving the physiological signal sent by the physiological signal acquisition module and carrying out emotion recognition and mental state assessment on the physiological signal by adopting a dynamic graph convolutional neural network algorithm in combination with a width learning system to obtain a mental state assessment result. The system can more accurately and strongly stimulate emotions, and can improve the accuracy of mental state assessment. The invention further provides a working method of the mental state assessment system, the method is more accurate and stronger in emotion stimulation, andthe mental state assessment accuracy degree is high.

Description

technical field [0001] The invention relates to the technical field of mental state assessment, and more specifically, to a mental state assessment system based on holographic projection technology and a working method thereof. Background technique [0002] Existing emotional stimulation methods mainly stimulate people’s emotions through pictures, videos, etc., such as stimulating the surprise emotions of the subjects by showing some surprising pictures, and stimulating people’s horror emotions by playing horror movie clips. However, such a stimulation method cannot provide a good immersive atmosphere, and it is not easy for the subjects to quickly enter the state, and there may be distractions, which makes the collected EEG inaccurate. [0003] Holographic projection technology is a technology that uses the principles of interference and diffraction to record and reproduce the real three-dimensional images of objects. The first step is to use the principle of interference ...

AI Technical Summary

Problems solved by technology

However, the existing EEG-based mental state assessment system uses electrodes to collect EEG signals, and then uses algorithms such as short-time Fourier transform and principal component analysis to process data, extract data features, and identify emotions in different frequency bands. However, the features extracted by this algorithm are not effective when applied to emotion recognition.
