1. A system comprising:
a plurality of sensors configured to continuously sense neuromuscular signals from a body part of a user; and
at least one computer processor programmed to:
determine based, at least in part, on the neuromuscular signals sensed from the body part of the user, a current position and/or orientation of the plurality of sensors on the user's body part;
present a user interface to the user indicating a current position and/or orientation of the plurality of sensors; and
generate a control signal based, at least in part, on the current position and/or orientation of the plurality of sensors on the user's body part, wherein the control signal causes the user interface to instruct the user to variably reposition the plurality of sensors to a different position on the user's body part based on the determined current position and/or orientation and further based on which position and/or orientation of the user's body part is associated with a specific set of training data generated from a specific input model.
