Oh, very cool. My undergrad thesis project was a $20-of-materials device that turned EMG readings into mouse cursor movements, it's always interesting seeing new frontiers in computer input methods. The source code was sadly lost in the great GitHub Christmas wipe of 2021, but it was really interesting to test it out on myself. Since EMG readings are 1-dimensional but cursor movement is 2-dimensional, I decided to make it a beat based system, like a rhythm game - a small flex moved the cursor proportionally, a large flex rotated the movement of the next cursor movement 90 degrees counterclockwise.
