Motion detection accessories
Xbox One: Xbox One comes with the redesigned and improved Kinect device, which Microsoft says can track motion better. The Kinect has a 1080p camera, and uses a multi-microphone array with noise isolation to hear voice commands.
PlayStation 4: The PlayStation Eye, the Sony motion detector for game consoles, is sold separately from the PS4 for $60. However, it is nonessential to total game play.
Bottom Line: If motion activated games are your weapon of choice, Xbox One may be the best route, but if not, PS4 offers just as much.
