Magnetic levitation monitoring and control using iPod

This video shows a magnetic levitation experimental testbed being commanded using an iPod Touch. The user commands the position of the ball using a slider at the bottom of the iPod graphical user interface (GUI). The measured position of the ball is communicated to the GUI in real-time, displayed in a textbox, and used to animate the ball position on the GUI. Alternative iPod interfaces allow the user to manipulate gains of an algorithm controlling the ball position.
