Due to the highly hands-on, rough nature of such applications, the industrial joystick tends to be more robust than the typical video-game controller, and able to function over a high cycle life. This led to the development and employment of Hall effect sensing to such applications in the 1980s as a means of contactless sensing. Several companies produce joysticks for industrial applications using Hall effect technology. Another technology used in joystick design is the use of strain gauges to build force transducers from which the output is proportional to the force applied rather than physical deflection. Miniature force transducers are used as additional controls on joysticks for menu selection functions.
