An on-screen keyboard is a software only approach that creates a virtual keyboard emulator. A keyboard image is visually displayed to the user, where the keys are "typed" (clicked) via the pointing device (whether mouse, trackball, pen, touchscreen, etc.). The software interfaces with the operating system, which is "told" that keystrokes are being generated (as if by a physical keyboard). Any underlying software application used by the operator then reacts as though the keystrokes were typed from a physical keyboard. This creates an entirely new way for computer operators to work with applications. For example, with a touchscreen interface and an on-screen keyboard, the user can operate the system without the need for a mouse or physical keyboard.
