One of the great things about the myoelectric signal processor project is that it is all “open source,” which means others can have access to the software to collaborate and make improvements.  In order to keep the software open source, all of the signal processing is being performed in the commonly used software Javascript.  Data analysis is being performed to measure the range and repeatability of the measurements (for the truly data-savvy out there, the student is using a Linear Descriminant Analysis (LDA), as well as using a Gaussian statistical model). Additionally, the signal processor will be able to plot out the  voltages being recorded by the electrodes in real time. This plot is similar to an electrocardiogram signal and will show voltages versus time. This will be useful because it will allow the team to see the voltage reactions from different movements and it will also allow them to make sure that the electrodes and circuit board are properly connected and all voltages are being recorded.
