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
