This article describes an improvement for the input devices of personal computers, computer terminals, or work stations. It is proposed to integrate the function of a computer keyboard with the function of a mouse (hand-held device for controlling continuous movement of the cursor on a display). The advantage is that the mouse can be moved without removing the fingers from the keyboard (otherwise, when moving fingers between mouse and keyboard, spatial orientation may be lost). A specific implementation is suggested in which the keyboard is mounted on roller balls and the mouse is positioned at the bottom of the keyboard in a central location. Furthermore, a resting bar for the balls of the hands (covered with rubber to increase friction) is mounted at the front side of the keyboard to simplify guiding.
