Versatility of human body control through low-cost electromyographic interface

An increasing trend in Human-Machine Interaction is the development of a tighter connection between the human user and the device. This paper analyses the possibility of creating a low-cost system that enables a person to use a group of muscles to control a different part of his body using Electromyography (EMG). This system features an EMG reader, two processing boards and a robotic hand, and was tested in both ideal and practical conditions. Despite being possible to see satisfactory results in some subjects’ first uses, it was concluded that the practicing time was a key factor on the precision of the artificial limb control.
