Computer cursor control joystick and its control method

摘要

The present invention discloses a method of controlling a computer cursor by a joystick, which uses at least one X-axis variable resistor and one Y-axis variable resistor of a rotary mechanism of a joystick to produce a horizontal potential signal and a vertical potential signal to compute the potential variation of said horizontal potential signal and said vertical potential signal and produce a vector displacement signal, and then converts said vector displacement signal into a cursor control code and outputs such code to a computer, so that the cursor of the computer will generate coordinates with respect to its horizontal and vertical movements in order to achieve the purpose of controlling the movement of the computer cursor.
