APPARATUS AND METHOD FOR CONTACT FREE INTERFACING BETWEEN USER AND SMART DEVICE USING ELECTROMYOGRAM SIGNAL

摘要

According to an embodiment of the present invention, an apparatus allows a user to interface with a screen of a smart device in a contact free manner, and comprises: an electromyogram electrode to measure an electromyogram signal according to a distance between a thumb and an index finger; a transmission unit to transmit the electromyogram signal to a smart device; an attaching means to fix the electromyogram electrode and the transmission unit on a hand of a user; a calculation unit to derive a displacement value of the thumb and the index finger of the user matching the electromyogram signal transmitted to the smart device; and a control unit to perform a pinch-to-zoom operation with respect to the screen of the smart device. The embodiment of the present invention uses an electromyogram signal according to a movement of the fingers of the user as an input signal to precisely recognize a motion, and can perform an interface between the user and the smart device in a contact free manner without being greatly affected by a distance.
