NYTimes: Microsoft's headline announcement at this year's E3 gaming conference was a motion-detection system housed in a sensor bar that plugs into your Xbox 360's ports. The pull-out-all-the stops unveiling included an on-stage appearance by Steven Spielberg who raved "I think what Microsoft is doing is not about reinventing the wheel. It's about no wheel at all."
I had my doubts.
First, we've all seen motion tracking before. Remember the Intel Play Me2Cam (1999)? How about Sony's EyeToy (2003), which offered several motion sensing party games for the PlayStation 2, (including a burglar alarm)? There was also Hasbro's ION (2006). Sony's PS3 PlayStation Eye (2007) came with motion games like Eye of Judgment. All came with big claims but limited success.
