Wearable devices and associated band structures for sensing neuromuscular signals and identifying hand gestures and methods of use thereof

A non-transitory computer-readable medium storing instructions that, when executed by one or more processors of a band of a wrist-wearable device, cause the one or more processors to:

• sense, with a plurality of sensors arranged in the band, electrical signals travelling through a wrist of a user when wearing the band;
• output, from the plurality of sensors, signals comprising information indicating a movement of at least one of the wrist, a hand, and fingers of the user;
• determine, with the one or more processors, a gesture of the user based at least in part on the information indicating the movement of at least one of the wrist, the hand, and the fingers of the user;
• and
• output, from the one or more processors, a flag that identifies the determined gesture.

A method of operating a band of a wrist-wearable device, the method comprising:

• sensing, with a plurality of sensors arranged in the band, electrical signals travelling through a wrist of a user when wearing the band;
• outputting, from the plurality of sensors, signals comprising information indicating a movement of at least one of the wrist, a hand, and fingers of the user;
• determining, with one or more processors, a gesture of the user based at least in part on the information indicating the movement of at least one of the wrist, the hand, and the fingers of the user;
• and
• outputting, from the one or more processors, a flag that identifies the determined gesture.
