Interested in hacking a PC gamepad rumble pack but need some advice

Here's my overall goal, I'm just not sure what the best way to go about things is, so I figured I'd ask the forum. I had an easy chair that had vibrating motors installed in it that I could control with a wired remote, and I've removed all the wiring and the motors so I can put them in a new chair, but what I really want to be able to do is hook the controls for the vibrating motors up so that they receive input to rumble from the games I'm playing, and rumble with the same intensity/length that the rumble pack in a PC gamepad has, I'm just not sure what the best way would be to connect the rumble input so that it controls the motors in the chair. Would my Arduino board help, or would there be a better way of doing this?
