Episode notes
Neuromotor Interface Basics
- Neuromotor interfaces read muscle electrical activity to detect neural signals indirectly.
- This approach is a non-invasive alternative to brain-computer interfaces reading brain activity directly.
AI Scaling Laws Enable Generalization
- AI scaling laws apply to neuromotor interfaces improving model performance with larger diverse datasets.
- Training on many people data enables generic, cross-user neuromotor control without individual calibration.
Wristband Design Tradeoffs
- Design wristbands to balance miniaturization with signal fidelity for accurate electromyography.
- Prioritize comfort, aesthetics, and battery life for all-day wearable consumer devices.
