Nintendo unveils MotionPlus accessory

Nintendo has peeled the plastic off its MotionPlus accessory for the Wii remote.

This slots into the bottom of the controller and tracks your arm position and orientation giving off "unmatched" precision, according to the Nintendo website.

There are few other details on how exactly it works or what it does, although it boasts a "true 1:1 response" to your movement.

More information is expected tomorrow at the Nintendo E3 press conference. We will be bringing you live coverage of that from 5pm UK time.
