ABSTRACT:
An improved computer mouse allows a computer operator to interactively adjust horizontal and vertical resolution by depressing switches on the mouse frame and moving the mouse frame on a flat surface. Optional indicators on the mouse frame indicate a plurality of resolution settings. An internal sounding device within the mouse assembly provides audio feedback as the resolution is changed. The invention connects to a standard Personal Computer (PC) through a serial RS-232 port or a standard parallel "bus mouse" interface and contains provisions for vendor unique interfaces. Keyboard entry is not required in order to adjust the resolution setting of the mouse. Memory resident dynamic tracking programs are not needed to modify the resolution of the mouse, thereby freeing up computer memory for other applications.
