Before you begin:

There are many user-input devices beside the traditional keyboard and mouse.

For example, user input can come from a joystick, a touch screen, a microphone, or other devices that allow great flexibility in user input.

These devices are collectively known as Human Interface Devices (HIDs). The raw input API provides a stable and robust way for applications accepting raw input from any HID, including the keyboard and mouse.
