Week Ten Updates

The final touches were put on the project. The algorithm was changed slightly to include a temporary variable so that the command function is only called when the signal energy crosses the threshold. This prevents the function from executing the same command many times rapidly.

The electrodes continued to cause problems. The alligator clamps tend to peel the corners off of the face, and the electrodes are so sensitive that they must be completely attached or they will not detect muscle contractions properly. More adhesive electrodes would mitigate this problem.

We recorded a demo demonstrating control of foobar2000 using EMG signals.

 

The final script and command function can be found here:
