EMG Actuated Maze

We have all seen, used, and are familiar with the concept of a tilting marble maze where a ball is moved through a maze by tilting one end up and then the ball rolls in the opposite direction. Generally, the parts of the maze that are raised up are actuated directly by the individual, in this iteration of the tilting marble maze, you will never touch the game board. In this version, you and another participant will actuate the board with EMG (electromyography) signals. Reimagine how you can use your body to complete this challenge.
