The invention discloses an emotional state
objective evaluation system based on electroencephalogram signals, and relates to the technical field of
mental health assistance for art therapy healing, and the
system comprises a data collection module which is used for synchronously collecting multi-
modal physiological and behavior data when a subject accepts an art therapy healing intervention process based on audio-visual content; and the input end of the emotional state evaluation module is connected to the
data acquisition module, and the emotional state evaluation module is used for receiving and
processing the multi-
modal data. According to the emotional state
objective evaluation system based on the electroencephalogram signals, multi-
modal physiological behavior data and subjective feedback are fused, multiple independent
verification and artificial arbitration mechanisms are introduced, the objectivity and reliability of emotional state evaluation are enhanced, and the system can accurately evaluate the emotional state according to the real-time
evaluation result. According to the method, personalized healing intervention is dynamically matched and triggered from the pre-labeled content
library, so that the conversion from static observation to dynamic response is realized, and the artistic healing process can adapt to the emotional change of the subject in real time.
