Brain-Machine Interfaces with Decoded Neural Feedback
Quick fact
In 2016, a paralyzed man named Nathan Copeland used a brain implant to feel the touch of a robotic hand, with the sensation delivered directly to his brain via micro-electrodes—the first demonstration of human bidirectional brain-machine interface.
Why this is interesting
Imagine moving a robotic arm with your thoughts alone—now imagine feeling the texture of what that arm touches. How can a machine both read your intentions and send messages back to your brain?
