What is force feedback? The joystick will vibrate in attempt to give a more realistic feel to action in gameplay.
Vibrating alone is not force feedback. Many console and PC controllers can vibrate but they are not force feedback controllers. Force feedback is the application of physical force in response to user input. Used, for instance, in arcade games and car and plane simulators. It is usually more of a constant force in a specific direction depending on the current action going on in-game.Force feedback controllers can vibrate as well, but vibrating alone is not force feedback. There is a substantial difference between the two, and I wish that marketers wouldn't advertise vibrating controllers as 'force feedback' controllers.
There is a significant difference between playing my Gran Turismo 3 game with my dual-shock controller (vibration) and playing it with my force-feedack steering wheel. I couldn't beat the harder races until I started using the wheel so that I was able to 'feel' the road surface (for instance, like when the car would begin to slide or fishtail). BTW, I don't think a lot of people really appreciate just how realistic GT3 is when it comes to real-world physics...
