Why doesn't Sony's Playstation 3 controller give you the shakes? According to the company, the familiar DualShock-style force-feedback was dropped from the new controller in favor of motion-sensors. However, Immersion Technologies -- which sued Sony for using its haptic tech in earlier controllers -- believes that the controller could be made to rumble, and has some ideas for Sony about how to do it. The catch: Sony needs to drop its appeal of the verdict in Immersion's 2004 lawsuit, and pay Immersion the $90 million that the judge in that case awarded the company. And, of course, Sony would have to pay Immersion for whatever technology they use in the PS3 controller. Frankly, it doesn't sound like a bad deal. By continuing to appeal the lawsuit, Sony's risking another loss and piling up legal fees, and by dropping the shock, they're left with a controller that many have called a weak attempt to copy the Wii. Working with Immersion on a haptic solution could solve both problems.
