A human interface device or HID is a type of computer device that interacts directly with and takes input from humans. The term "HID" most commonly refers to the USB-HID specification. The term was coined by Microsoft (as they worked in the USB SIG?).

Common HIDs

• Keyboard
• Mouse, Trackball, Touchpad, Laptop eraser
• Graphics tablet
• Joystick

Less Common HIDs

• Anything Vehicle-like - Just the sticks, wheels, buttons and pedals. Those HIDs talk to the computer that renders the simulation, and outputs results to the screen, and maybe your seat.
• Hand Glove
• Stomp Pad

Most operating systems will recognize USB HID devices, like a keyboard or mouse, without needing a special driver (though you may want one for advanced features). You should get some message saying that a "HID-compliant device" has been recognised. This is generally not the case with the direct PS/2 5-pin DIN connectors which preceded USB, as these are recognised as native hardware by the BIOS firmware upon booting.

A USB HID is described by the USB human interface device class.
