BEADDA is an AI-driven physiotherapy system integrating EEG, EMG, and computer vision to measure cognitive and physical performance in real time. I built a unified biosensing pipeline by integrating OpenBCI EEG and EMG hardware with LabStreamingLayer (LSL) to synchronize multi-channel neural and muscle signals. I implemented full signal-processing workflows—including filtering, artifact reduction, calibration, and feature extraction—to create reliable neural and muscular metrics suitable for downstream AI models. This system enables real-time assessment of user state, forming the foundation for adaptive physiotherapy feedback and AI-guided movement correction.
