Abstract: The ADS1299 chip of the OpenBCI development board is used as the core design system to collect non-invasive EEG signals and transmit the data to the upper computer via the WiFi module for display to realize portable monitoring of EEG. It can perform signal preprocessing and other operations on the upper computer as required. It uses the graphical editing language LabVIEW to develop according to the "producer-consumer" model. The producer part is mainly responsible for data analysis and reception, and it judges whether the data is lost. The consumer part is mainly responsible for data preprocessing, waveform display, recording, etc. The designed monitoring device is mainly realized by the EEG cap, OpenBCI development board, WiFi module, battery and other components. Using this monitoring device, it is possible to further study brain-controlled electronic entertainment products. Through this interactive behavior, you can achieve more precise control of your brain and enhance the immersive experience.
