Hypnosis Depth Detector

Abstract

A hypnosis depth detector, comprising: an electroencephalographic electrode, an electroretinographic electrode, a reference electrode, and an analog-to-digital converter, a filtering circuit, and a processor connected in that order. An acceleration sensor is connected to the processor. The electroencephalographic electrode is used for detecting an electroencephalographic signal of a user during sleep. The electroretinographic electrode is used for collecting an electroretinographic signal of the user during sleep. The acceleration sensor is used for detecting a motion signal produced by an arm response of the user. A speaker is used for playing audio to the user. The analog-to-digital converter converts the electroretinographic signal and the electroencephalographic signal to digital signals. The filtering circuit filters the electroretinographic signal and the electroencephalographic signal at a low frequency and outputs the filtered signals to the processor. The processor is used for determining, on the basis of the electroencephalographic signal, the electroretinographic signal, and the motion signal, a current hypnosis depth of the user. The hypnosis depth comprises a scale 1 hypnosis depth, a scale 2 hypnosis depth, and a scale 3 hypnosis depth. The invention can improve identification accuracy and efficiency.

Description

technical field [0001] The invention relates to the technical field of sleep aids, in particular to a hypnosis depth detector. Background technique [0002] During sleep, the human body undergoes a process of self-relaxation and recovery. Therefore, good sleep is a basic condition for maintaining good health. However, due to reasons such as high work pressure and irregular life schedule, some people have poor sleep quality, manifested as insomnia, waking up in the middle of the night, etc. [0003] Intelligent assisted sleep is a sleep method combined with modern technology. When the subjects enter the hypnotic state, their susceptibility to suggestion is significantly improved, they can maintain a close relationship with the hypnotist, and they will accept their hints without criticism. When hypnotism is used to assist sleep, when the hypnotist is hypnotized by the hypnotist, the hypnotist can issue sleep instructions to make the hypnotized person fall asleep. Compared w...

AI Technical Summary

Problems solved by technology

For each level of hypnosis depth, there are corresponding judgment standards, which are judged according to the action characteristics of the hypnotized person. For intelligently assisting sleep through hypnosis, correct recognition is the prerequisite for the next stage of hypnosis However, this generally requires a hypnotist to make a judgment based on sufficient experience, and it is difficult for ordinary users to judge. At the same time, these detection methods can identify the depth of hypnosis, and the accuracy is difficult to guarantee and the efficiency is low.
