Mind-Controlled Gaming: Build Your Own BCI
Build a brain-computer interface using the BioAmp EXG Pill and Arduino Uno R4 that enables video game control through focus detection and eye blink sensing via EEG and EOG signals.
Firmware:Arduino
Use Cases:Education
Overview
This project guides you through building a complete brain-computer interface for gaming. It combines EEG-based focus detection (beta waves at 13-30 Hz) with EOG-based eye blink detection to create a hands-free game controller.
Hardware Required
- BioAmp EXG Pill
- Brain BioAmp Band (or gel electrodes)
- BioAmp Cable v3
- Arduino Uno R4 Minima
- Jumper cables
- Nuprep Skin Preparation Gel
How It Works
The system uses two control mechanisms:
- Focus Detection: Beta wave analysis detects concentration levels for primary game actions
- Double-Blink Detection: EOG signals from eye blinks trigger secondary game actions
The Arduino Uno R4's CMSIS-DSP library handles real-time FFT processing of the brain signals.
What You'll Learn
- Combining EEG and EOG for multi-modal BCI control
- Real-time signal processing with CMSIS-DSP
- Building practical brain-controlled applications
