An apparatus, a system, and a method for transferring data from a terminal to an Electromyography (EMG) device are provided. The method includes detecting a user motion, determining whether the user motion corresponds to a motion associated with requesting data to be transferred from the source terminal to the EMG device, and if the user motion corresponds to a motion associated with requesting data to be transferred to from the source terminal to the EMG device, transmitting to the source terminal a request for the data according to the user motion.
