User interface control of responsive devices

An apparatus comprising

• two or more user interface devices configured to generate outputs,
• at least two of the two or more user interface devices having at least two electroneurography sensors configured to detect, at a dorsal side of a wrist of the human, nerve signals associated with intended contractions of two or more muscles and to generate corresponding sensor outputs,
• a processor configured to derive information corresponding to and representing nerve signals from the sensor outputs of the electroneurography sensors,
• at least one of the user interface devices comprising an inertial measurement unit (IMU),
• at least one of the user interface devices comprising a wrist-worn user interface device, two or more responsive devices, and
• an interpreter configured (i) to generate interpreted outputs based on (a) the information derived by the processor corresponding to and representing nerve signals from the sensor outputs of the electroneurography sensors, (b) a joint consideration of the information derived by the processor corresponding to and representing nerve signals from the sensor outputs of the two electroneurography sensors of each of the user interface devices, and (c) a separate consideration of the information derived by the processor corresponding to and representing nerve signals from the sensor outputs of each of the two electroneurography sensors of each of the user interface devices, and (ii) to provide the interpreted outputs to a controller configured to effect actions by the two or more responsive devices.
