A joystick for generation of directional control signals for computers, video games, remote controllers, and other electronic devices and instrumentation. The present invention comprises a resistive membrane sensor and an actuator for coupling directional forces onto the membrane sensor. The resistive membrane sensor is comprised of two insulating substrates with resistor rings on each substrate, conductive leads, and a pressure-variable resistor. Increasing pressure on the actuator and membrane sensor decreases the resistance of the pressure-variable resistor in series with the resistor rings. An electronic circuit measures the membrane sensor and converts the resistances into the X and Y components of the force vector acting on the joystick. An alternative membrane sensor comprises a resistive ring, a conductive ring, and a pressure-variable resistor. |
