But, why would EMG be used instead of other input techniques such as computer vision or speech recognition? As stated by \cite{Saponas_2010}, occlusion and lighting limit the capabilities of computer vision and speech recognition may be socially awkward in most situations. To further strengthen the usage of EMG, Saponas stated that the EMG approach "allows people to use their fingers for input without any sensing technology on or near their hands."   EMG when used and applied to computer, can form muscle-computer interfaces. In an experiment conducted by \cite{saponas2008demonstrating}, 10 sensors worn in a narrow band around the upper forearm demonstrated reliable interpretations of the muscle movements. They were able to differentiate the position and the applied pressure of finger presses; and, presses. And,  they were able to classify tapping and lifting gestures across all of the five fingers. The problem with this however, is that lots of sensors may be cumbersome to the person. \begin{comment}  find source  \end{comment}
