EMG Sensor-based Two-Hand Smart Watch Interaction

Abstract

These days, smart watches have drawn more attention of users, and many smart watch products have been launched (Samsung Gear series, apple watch and etc.). Since a smart watch is put on the wrist, the device should be small and unobtrusive. Because of these features, display of the smart watch is small and there is a limitation to interaction. To overcome the limitation, many studies are conducted. In this paper, we propose a two-hand interaction technique that obtains posture information of a hand using electromyography (EMG) sensor attached to the arm and to make input interaction to a smart watch different depending on each posture. EMG sensors recognize information about a user's hand posture, and the non-dominant hand is used for smart watch inputs. In this way, different function is executed depending on postures. As a result, a smart watch that has limited input methods is given a variety of interaction functions with users.
