Abstract
A hand tracking system includes a wearable device configured to be worn on a user's wrist. The wearable device includes one or more transmitters, at least one receiver, and a controller. The transmitters generate an electric field that is altered by movement of a hand, fingers, and/or wrist of the user. The wearable device may also include one or more microphones that are configured to detect taps and so forth by one or more fingers of the hand. In some embodiments, the microphones are positioned such that they detect the taping my monitoring acoustic waves propagating through the tissue of the hand. The controller uses information captured by the receivers and/or the microphones and a model (e.g., machine learning model) to recognize a hand gesture.
