We grab USB controllers from the CNMAT sensor library, hook them to our machines and explore simple programs that show the data they provide. Examples include:

* Digitizing tablets (Wacom),
* game controllers (WII, Nunchuck and WIIfit), gamepads and joysticks
* MIDI Fader boxes (Behringer BCF2000)
* HID devices, e.g. , switch boxes, 3D mouse (SpaceNavigator)
* Built-in Mouse Trackpad and Keypad
