Gaming accessory company Splitfish already brought motion sensing to the PS2 controller. Now the bring rumble back onto the Sony PS3 controller with the SensorFX.

To avoid issues with Immersion’s Rotating Mass Patent, Splitfish uses technology with no moving parts. We are in contact with Splitfish about a photo of the SensorFX, but they do not have one yet.

It will be interesting how well this works. Splitfish is creative that is for sure. We got in contact with them back in 2005 when they introduced the eyeFX 3D glasses for the PS2.
The SensorFX feedback system can be sold as an add-on to existing controllers or as an imbedded feature that is part of a standard controller.
The SensorFX has two modes, one for games that have force feedback support already built in and the other mode that relies on motion tilt sensing and button use and other actions to trigger the SensorFX tactile feedback.
