Controller Info:

E3 2005 showcased Sony's "boomerang" design, which was abandoned due to poor public reaction and replaced with an upgraded wireless version of the DualShock 2 at E3 2006. The new controller features finer analogue sensitivity, more trigger-like R2 and L2 buttons, an Xbox 360 like central button, and a USB mini-B port for charging the internal battery and use for wired play. There are four numbered LED indicators, to identify and distinguish multiple wireless controllers. The major feature revealed was the ability to sense both rotational orientation and translational acceleration. Games that use this feature will come with an option to turn it off.

Sony has stated that because of these sensors, the rumble feature of the previous controllers has been removed, reasoning that the vibration interferes with motion-sensing. Haptics developer Immersion Corporation (who successfully sued Sony) expressed skepticism of Sony's rationale, and has since introduced tilt and motion-sensing which filters out vibration in software.
