what is a joystick in computer

A Joystick is an input device consisting of a flexible stick that pivots on a base and reports its angle or direction to the device it is controlling. It is is a cursor control device used in computer games and assistive technology . The Joystick, which got its name from the control stick used by a pilot to control the ailerons and elevators of an airplane, is a hand-held lever that pivots on one end and transmits its coordinates to a computer. Joysticks are often used to control video games, and usually have one or more push-buttons whose state can also be read by the computer.

How does a computer joystick work?

It works on a simple principle, where the machine accepts the hand movement with the help of the sensors and converts it into a mathematical code, which then moves the virtual body in the computer in the same way. The Joystick starts working only when it is connected to the computer or the gaming device.

Types Of Joystick

There are five types of joysticks:

+  Digital Joysticks

+  Paddle Joysticks

+  Analog Joysticks

+  Pc Analog Joysticks

+  Joypads

+  Digital Joysticks

what is a Digital Joysticks in computer

Digital Joysticks are the most common Joysticks used for PCs, employing simple left, right, up, down and firing commands. They are also called “Atari-style” Digital Joysticks. Paddle Joysticks consist of one knob used to control the game and one firing button. This is one of the oldest Joysticks.

+  Paddle Joysticks

what is a Paddle Joystick

A Paddle Joystick is a game controller with a round wheel and one or more fire buttons, where the wheel is typically used to control movement of the player object along one axis of the video screen. A paddle controller rotates through a fixed arc (usually about 330 degrees); it has a stop at each end.

+  Analog Joysticks

what is a analog Joystick

An Analog Joy Stick  is an input device for a controller (often a game controller) that is used for two-dimensional input. While digital sticks rely on single electrical connections for movement (using internal digital electrical contacts for up, down, left and right), analog sticks use continuous electrical activity running through potentiates to measure the exact position of the stick within its full range of motion.

+  Pc Analog Joysticks

what is a Pc Analog Joysticks

A PC Analog Joysticks combine both concepts presented in the digital and paddle joysticks; they control the game like a digital joystick, but also use potentiometers to measure the movements like the paddle joysticks.

+  Joypads

what is a joypad

A Joypad is used for playing video games of many types, including sports, first-person shooters, role-playing, and others. The picture shows an example of the Xbox 360 controller for Windows and a popular Joypad for the computer and consoles.
