Despite several decades’ research, robust, responsive and intuitive control schemes remain elusive. Current commercial hardware advances
offer a variety of movements but the control systems are unnatural, using sequential switching methods triggered by specific
sEMG signals. However, recent research with pattern recognition and simultaneous and proportional control shows good promise for
natural myoelectric control. This paper investigates several sEMG time domain features using a series of hand movements performed by 11 subjects, taken from a benchmark database, to determine if optimal classification accuracy is dependent on feature set size. The features were extracted from the data using a sliding window process and applied to five machine learning classifiers, of which Random Forest consistently performed best. Results suggest a few simple features such as Root Mean Square and Waveform Length achieve comparable performance to using the entire feature set, when identifying the hand movements, although further work is
required for feature optimisation.
