The Xio from Forcetek is ... well, it's interesting. Rather than reducing your controller to a wand or removing the controller altogether, the Xio is a harness that attaches to your arm. The device tracks the motion of your wrist as you turn it and twist it, translating the motions into in-game actions. We got to try it out at E3 with Tom Clancy's HAWX, and it was a novel experience to say the least. We were told by Forcetek that the ultimate goal is to incorporate the technology into an actual suit that can be used in an augmented reality experience of some sort. So yeah, wild.
