ABSTRACT:
A touch-control mouse provides rapid and accurate control of the positioning of a cursor on a computer display screen, and includes a laminated touch-control film assembly, an aluminum supporting board, a press button switch set, a signal processing circuit board, and a dust-protective hanging case. Drawing using a finger on x-axis and y-axis resistance planes of the laminated touch-control film assembly results in variable potential value for x, y coordinates. The value of potential variation is calculated through a single-chip microprocessor to indicate relative direction, speed and amount of displacement on x, y coordinates. The signal of the relative direction, speed and amount of displacement is further is further sent by the single-chip microprocessor through a standard RS-232 connector to one of the serial communications ports of a PC to rapidly and accurately control the positioning of the cursor on the computer display screen.
