Virtual reality interactive emotion detection and regulation system based on brain-computer interface

Abstract

The invention discloses a virtual reality interactive emotion detection and regulation system based on a brain-computer interface, and the system comprises a stimulation module which is used for transmitting stimulation information, playing audios and videos expressing different emotions through a video or a three-dimensional scene, and transferring the emotion of a user through the motion of a virtual person; the feedback module is used for transmitting and feeding back a result processed by the data processing module and helping the user to adjust real-time emotion; the data acquisition module is used for acquiring and recording electroencephalogram signals of a user; and the data processing module is used for processing the electroencephalogram signals, including state marking of electroencephalogram data, data segmentation, feature extraction, classifier model calculation and generation of corresponding feedback commands. According to the system, the problems that an existing electroencephalogram emotion detection system is single in feedback form and cannot achieve interaction are solved, the brain-computer interface technology and the virtual reality technology are combined, the interactive emotion detection and regulation system based on the virtual human is created, emotion detection and emotion regulation are achieved, and good use experience is achieved.

Description

technical field [0001] The invention relates to the technical fields of brain-computer interface technology, virtual reality technology and emotion induction, detection and regulation, in particular to a virtual reality interactive emotion detection and regulation system based on a brain-computer interface. Background technique [0002] By definition, emotion is a general term for a series of subjective cognitive experiences, including but not limited to people's attitudes, experiences and corresponding behavioral responses to objective things. EEG is one of the effective ways to understand how the human brain works harmless, painless and operable, so we hope to understand a person's emotional state through EEG. Algorithmically, emotion recognition is a key task, but for practical applications, emotion regulation is even more critical. However, some people have difficulty regulating their emotions according to their thoughts. Our focus is on proposing a system that is bene...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the current EEG emotion detection system has a single feedback form and cannot realize interaction, etc., and proposes a virtual reality interactive emotion detection and control system based on brain-computer interface. Combining with reality technology, an interactive emotion detection and regulation system based on virtual human is created. The system uses the expression of virtual human to display the user's emotional state, and gives feedback to the user to realize emotion detection and emotion regulation. After obtaining a good classification Accuracy while obtaining a good user experience
