A Meditative Smartspeaker Based On Electroencephalogram

An intelligent meditation box system is researched,which is specially designed for insomnia and high pressure crowd,and with the function of sleep and decompression.It is based on the design of wearable electroencephalogram(EEG)and neural plasticity theory.It combines the new technology and new thinking such as brain machine interface,magnetic levitation and intelligent sound box.The wavelet transform is used to process the EEG information,then the feature is extracted and then presented in a visual way to help the users to relax and keep goodSleep.A meditative smartspeaker based on electroencephalogram mainly composed of three parts: Meditation box,magic cube and brain wave instrument.The brain wave instrument can collect the EEG information,and the EEG information is transmitted through the Bluetooth ble to the meditative speaker.The meditative speaker is used to play music and light hints to help the users to carry out meditation training or promote sleep after the analysis of the brain information.The trainees' meditation immersion,concentration of the brain and relaxation can be visualized visually by means of light,The idea of magic cube,3D animation and so on,EEG data are also uploaded to mobile app and cloud server side for further analysis and processing;The smart speaker can be controlled by voice;it can be used for weather forecast and alarm clock setting;it also has common music playing functions such as Bluetooth music,DLNA,airplay and so on.The smart speaker can be controlled simply by buttons,sliding touch,six axis sensor and so on,and network configuration and operation control can be carried out by mobile app.The main work and research contents are as follows:(1)a complete set of smart speaker hardware is designed,and the hardware is tested and modified in various directions.The driver is written and tested corresponding to the corresponding hardware circuit.The circuit is optimized and modified according to the actual test results,and the driver is optimized to make up for some hardware defects according to some actual conditions.Depression.(2)complete the construction of compiling environment and the transplant of Linux operating system,and complete the software program design and test according to the requirement of the project,and realize the basic music function of the equipment as the intelligent sound box.(3)designed a set of meditation training process to visualize the state of EEG information,and meditate on users with the help of music.(4)the wavelet analysis is used to transform the original EEG information and quantify the degree of attention,so as to facilitate the use of meditation training function.The smart speakers developed by this research not only meets the needs of users for basic music functions of smart speakers.,but also integrates the new technology and new thinking,such as biological EEG,magnetic levitation,etc.,and perceives the brain state in real time by visualizing the mental state.Helps users meditate and relax and sleep well.Can be widely used in many fields such as mental health,education,training,medical care and so on.
