The final great feature about the dualshock 2 controller is it’s vibration feature. In a racing game, when you slam into a wall, you can feel the impact in your hands! The specific name for this is Force Feedback.This provides a tactile feature to the controller, allowing you to feel a sensation, even when you may not see it.

Force feedback is accomplished through the use of a very common device, a simple electric motor. In the Dualshock 2 controller, two motors are used, one in each handgrip. The shaft of each motor holds an unbalanced weight. When power is supplied to the motor, it the weight spins.

Because the weight is unbalanced, the motor tries to wobble. But since the motor is securely mounted inside the controller, the wobble translates into a shuddering vibration of the controller itself.
