Query: Effect of Analysis Window and Feature Selection on Classification of
  Hand Movements Using EMG Signal   Electromyography (EMG) signals have been successfully employed for driving
prosthetic limbs of a single or double degree of freedom. This principle works
by using the amplitude of the EMG signals to decide between one or two simpler
movements. This method underperforms as compare to the contemporary advances
done at the mechanical, electronics, and robotics end, and it lacks intuition.
Recently, research on myoelectric control based on pattern recognition (PR)
shows promising results with the aid of machine learning classifiers. Using the
approach termed as, EMG-PR, EMG signals are divided into analysis windows, and
features are extracted for each window. These features are then fed to the
machine learning classifiers as input. By offering multiple class movements and
intuitive control, this method has the potential to power an amputated subject
to perform everyday life movements. In this paper, we investigate the effect of
the analysis window and feature selection on classification accuracy of
different hand and wrist movements using time-domain features. We show that
effective data preprocessing and optimum feature selection helps to improve the
classification accuracy of hand movements. We use publicly available hand and
wrist gesture dataset of $40$ intact subjects for experimentation. Results
computed using different classification algorithms show that the proposed
preprocessing and features selection outperforms the baseline and achieve up to
$98\%$ classification accuracy.
