Development of sEMG Based Human Machine Interface Control System for Wrist Watch

Abstract

A Wearable Electromyography device includes the advantage of Electromyography (EMG) sensors and provides a wired or wireless human machine interface (HMI) for interaction with computing systems and attached devices associated with electrical signals generated by specific movement of the patient's muscles. An electromyogram (EMG) measures the electrical activity of muscles at rest and during contraction. Nerve conduction studies measure how well and how fast the nerves can send electrical signals. Nerves control the muscles in the body with electrical signals called impulses. These impulses make the muscles react in specific ways. Nerve and muscle problems cause the muscles to react in abnormal ways.Following initial automated self-calibration and positional localization processes, measurement and interpretation of muscle generated electrical signals is accomplished by sampling signals from the EMG sensors of the Wearable Electromyography Device. Initially, the Wearable Electromyography Device is donned by the user and placed into a coarsely approximate position on the surface of the patient's skin.
