Software defined radio and Bci remote connection and signal acquisition -- 2
Budget: $1,500 – $3,000 USD
The microcontroller acts as the initial sensing unit for EEG signals. Once these are detected, a MIMO antenna system is activated to further collect EEG data with higher precision through electromagnetic frequencies. This enhanced data is then sent to a computer running a BCI software that employs a P300-based method to facilitate communication and potentially even visualize what the person is seeing.
Here are some considerations for this setup:
1. **Precision**: The use of MIMO for 'virtual electrode placement' could potentially enhance the spatial resolution of EEG readings.
2. **Signal Quality**: MIMO can help improve signal-to-noise ratio, ensuring more accurate and reliable data transmission.
3. **Real-time Processing**: Both P300 detection and image reconstruction from brain signals require significant computational resources, so a powerful computer would likely be needed.
4. **Safety**: Care would be needed to ensure that the electromagnetic frequencies used are safe for human exposure.
5. **Synchronization**: Ensuring real-time or near-real-time communication between the microcontroller, MIMO system, and the computer would be crucial for effective BCI functioning.
6. **Security**: Given that sensitive brain data is being transmitted wirelessly, robust encryption methods would be essential to maintain privacy and data integrity.
7. **Calibration**: Proper calibration would be essential to match the 'virtual electrodes' to the corresponding areas of the brain for accurate P300 or visualizations
