Game Informer: DualShock 3

[MuGen]

It's basically the same as programming vibration function into a game. Except this time, they choose from 6 pin point motors, to isolate the vibration. Unless the game gets complicated and it has to vibrate in more than 1 motor, for example in a shooting game when you get shot in the leg and the shoulder causing 2 motor vibrations.

But, other than those complex games, it shouldn't be a problem to program individual shock.
