Abstract

This study analyses forearm muscle contractions that occur during movements of individual fingers. An amplitude threshold is implemented on the multiplied backwards difference (MOBD) of the signal to determine when a muscle contraction occurs, and is followed by a windowed variance threshold of the MOBD to determine which finger contracted. The purpose is to create a low-cost, computationally efficient method to determine specific finger contractions from the forearm. This method was able to differentiate the ring finger from the other fingers, which in comparison had a variance approximately ten times higher.
