EMG Sensors as Virtual Input Devices
Tomáš Tisančín, Adam J. Sporka, Ondřej Poláček · 2014
Electromyography (EMG), i.e. the detection and analysis of electric signals related to activity of muscles in humans, is often used to control prosthetic limbs. Recently, its importance started to grow also in the field of the human--computer interaction. We have established a simple electromyographic signal pipeline using two off-the-shelf hardware devices NIA in order to implement a virtual input device capable of emulation of mouse. A single NIA device is capable of signal composed of various components, including the EMG signal. We tested the reliability of recognition of elementary activities, such as fist clench, eye blink, etc. and the use of NIA as device which controls an emulation of the mouse. The placement on the forehead yielded least amount of errors.
