Abstract: A device, system or method may optionally control a function of a secondary device and include a body-wearable user device including a wireless transmitter configured to communicate directly with a wireless receiver associated with a secondary device, a sensor configured to sense a physical motion of at least one of the user device and a body part of a user of the user device and output a signal based on the physical motion, and a processor, communicatively coupled to the transceiver and the sensor, configured to generate a command to control a function of the secondary device based, at least in part, on the signal based on the physical motion from the sensor. The transceiver is configured to transmit the command to the secondary device.
