Abstract: Computerized systems, methods, and computer-readable storage media storing code for the methods enable feedback to be provided to a user based on neuromuscular signals sensed from the user. One such system includes neuromuscular sensors and at least one computer processor. The sensors, which are arranged on one or more wearable devices, are configured to sense neuromuscular signals from the user. The at least one computer processor is or are programmed to process the neuromuscular signals using one or more inference models, and to provide feedback to the user based on one or both of: the processed neuromuscular signals and information derived from the processed neuromuscular signals. The feedback includes visual feedback of information relating to one or both of: a timing of an activation of at least one motor unit of the user and an intensity of the activation of the at least one motor unit of the user.

Abstract: Methods and systems used in calibrating the position and/or orientation of a wearable device configured to be worn on a wrist or forearm of a user, the method comprises sensing a plurality of neuromuscular signals from the user using a plurality of sensors arranged on the wearable device, and providing the plurality of neuromuscular signals and/or signals derived from the plurality of neuromuscular signals as inputs to one or more trained autocalibration models, determining based, at least in part, on the output of the one or more trained autocalibration models, a current position and/or orientation of the wearable device on the user, and generating a control signal based, at least in part, on the current position and/or orientation of the wearable device on the user and the plurality of neuromuscular signals.
