CONTACTLESS INTERFACING DEVICE AND CONTACTLESS INTERFACING METHOD USING ELECTROMYOGRAM SIGNALS BETWEEN USER AND SMART DEVICE

摘要

An embodiment present invention relates to a device of interfacing a user with a screen of a smart device without contact. The device includes: an electromyogram electrode measuring electromyogram signals based on a distance between a thumb and an index finger; a transmission unit transmitting the electromyogram signals to the smart device; an attaching means attaching the electromyogram electrode and the transmission unit to a user′s hand; a calculation unit determining and outputting the highest value among output values of multiple sorting machines as a value of the displacement between the user′s thumb and the user′s index finger matched up with the electromyogram signals transmitted to the smart device; and a control unit performing a pinch-to-zoom motion to the screen of the smart device. The device of interfacing the user with the screen of the smart device is capable of precisely recognizing the motion by using the electromyogram signals based on the movement of the user′s fingers as input signals and interfacing the user with the smart device without contact and great influences of the distance.;COPYRIGHT KIPO 2016
