Abstract

The invention discloses an anxiety state detection and feedback system based on EEG signals. The detection and feedback system comprises specially-made portable EEG signal monitoring equipment, an EEGsignal analysis system and an anxiety state analysis algorithm. Working principles of the detection and feedback system are as follows: (1) the specially-made portable EEG signal monitoring equipmentcollects brain wave data of a user and transmits the brain wave data to the EEG signal analysis system in real time; (2) after receiving the data, the EEG signal analysis system decodes and preprocesses the data, and then performs signal identification through a brain wave data machine learning model by applying the anxiety state analysis algorithm; and (3) when the system identifies the signal data characteristics of the user entering an anxiety state, the anxiety state is fed back to the equipment and a terminal in real time for feedback.

Description

technical field [0001] The invention belongs to the technical field of EEG signal identification, and in particular relates to an anxiety state detection and feedback system based on EEG signals. Background technique [0002] Anxiety is a common emotional state, and an uncontrollable state of anxiety is called an anxiety disorder, which is a widespread mental health disorder. The occurrence of anxiety state is related to environmental factors, personality traits and other factors, and its occurrence is accompanied by strong abnormal brain activity. In particular, abnormalities in brain activity during anxiety will be reflected in abnormalities in EEG signals. Studies have shown that EEG signal abnormalities in anxiety states may be reflected in multiple dimensions, including frequency, power spectrum, coupling relationship, etc. With the continuous improvement of EEG signal recognition and analysis technology, the EEG brain wave monitoring technology of anxiety state is be...
