Abstract
Provided is an input device of a wearable wireless communication terminal. The device includes a biomagnetic sensing unit having a plurality of sensors for sensing biomagnetism caused by human muscular motion, a distinguishing unit for generating a signal(s) for distinguishing whether one or more sensing signals are inputted from any one(s) of the plurality of sensors of the biomagnetic sensing unit, a memory for storing a key mapping algorithm, and a controller for combining one signal or at least two signals outputted from the distinguishing unit, depending on the key mapping algorithm, and recognizing the combined signal as key input.
