Zuckerberg: Neural Wristband For AR/VR Input Will Ship "In The Next Few Years"
An entirely different approach to finger tracking is to sense the neural electrical signals passing through your wrist to your fingers from your brain, using a technique called electromyography (EMG). Theoretically this could have zero or even negative latency, perfect accuracy, work regardless of lighting conditions, and not be subject to occlusion. When discussing the technology in 2021 Reardon claimed that a recent breakthrough enabled decoding the activity of individual neurons for “almost infinite control over machines”.
Occlusion-free finger tracking of this quality and reliability could enable precise control of complex interfaces with incredibly subtle movements of your hand resting on your lap, making it an ideal input method for headsets and AR glasses.
