First Human Interface

A human interface device or HID is a type of computer device that interacts directly with, and most often takes input from, humans and may deliver output to humans. The term "HID" most commonly refers to the USB-HID specification.The term was coined by Mike Van Flandern of Microsoft when he proposed the USB committee create a Human Input Device class working group.The working group was renamed as the Human Interface Device class at the suggestion of Tom Schmidt of DEC because the proposed standard supported bi-directional communication.
