A non-invasive brain-computer interface for gaming, but the project is set up to also easily be repurposed as a BCI for other tasks, supporting a push the frontier movement. The BrainAccess Mini headset (8 channels @ 250 Hz) streams raw EEG; instead of feeding raw samples to a network (high latency, unstable training), a Feature Extraction Layer computes rolling 0.5 s power-spectral-density features across theta/alpha/beta/gamma bands, a Spatial GNN Layer message-passes over electrode nodes with spatial + functional-connectivity edges, and a meta-model head personalizes to each new brain in a 15-second in-game Calibration Wizard (press C). Live inference writes commands to the game at 4 Hz; keyboard keeps working simultaneously. Includes training (local + Modal cloud), a realtime EEG dashboard, replay mode for hardware-free demos, and an 82-test suite.
