isometric joystick

a joystick that doesn’t move when pressure is applied to it; the isometric joystick is sensitive to the force a person is applying. When used to control a pointer, as when embedded in the keyboards of many laptops, the isometric joystick controls the velocity of pointer movement. A major drawback of the isometric joystick is that it doesn’t provide any kinesthetic feedback to the user. In other words, the only non-visual feedback users get is the pressure they feel in contacting the joystick, but not in any motion.
