a joystick controller for generating analog signals representative of coordinate positions is characterized by a pair of members movable in orthogonal directions by a handle . each member carries at least one wiper contact adapted to slide linearly along an associated linearly extending resistor carried on a circuit board to generate the signals representative of coordinate positions . the use of linearly extending resistors for generating the signals , as compared with rotary potentiometers , provides for a reduction in size of the joystick controller , economies in its manufacture , and a high degree of linearity between handle positions and the signals generated .
