摘要：
A presentation device and an method of operating the presentation device may quickly move to a desired area on a map by adjusting a level of an electromyographic (EMG) signal even though a range of a motion of an arm is limited when searching the map using a wearable mobile device. The presentation device includes a first sensor unit configured to contact a measurement target and to obtain an electromyographic (EMG) signal from the measurement target； and a display controller configured to control a field of view (FOV) window for displaying a map area based on the EMG signal.
