This paper presents the work on a technology for Real time EMG acquisition and recognition of head movement. EMG signal detection and analysis is useful in various clinical and biomedical applications such as generation of control signal for prosthetic tool, but better solutions for detecting noise free EMG signals need to be developed. In this paper a simple and cost effective method for estimating human head movements from neck EMG signals is proposed. In this work, surface EMG signal is acquired from four main neck muscles (right and left sternocleidomastoid muscles and right and left trapezius muscles) using simple computer interface and processed by MATLAB based filter algorithm for online clean display.
