Apparatus and Method for Contact Free Interfacing Between User and Smart Device Using Electromyogram Signal

摘要

An embodiment of the present invention relates to an apparatus for interfacing a smart device screen in a non-contact manner by a user, comprising: an electromyogram electrode for measuring an electromyogram signal according to a distance between a thumb and index finger; a transmitter for transmitting the electromyogram signal to a smart device; An operation unit for deriving a displacement value between a thumb and a index finger of a user matched with an EMG signal transmitted to the smart device, an operation unit for pinching the screen of the smart device, And a control unit for performing the control. The embodiment can more accurately recognize the operation by using the EMG signal according to the movement of the user's finger as an input signal and can perform the interfacing between the user and the smart device in a non-contact manner without a great influence on the distance.
