Technical details

An analog joystick is a joystick which has continuous states, i.e. returns an angle measure of the movement in any direction in the plane or the space (usually utilizing potentiometers) and a digital joystick gives only on/off signals for four different directions, and mechanically possible combinations (such as up-right, down-left, &c.). (Digital joysticks were very common as game controllers for the video game consoles, arcade machines, and home computers of the 1980s.)
