Of the three motion-sensing products made available for the current flock of consoles, Microsoft's Kinect device for the Xbox 360 appears to be more than a simple gimmick.
With Kinect, gamers don't need to use a controller. All functions are carried out by gestures. Even when using Kinect to access the console's core features, there's a hint of Star Trek when commanding the device for specific tasks.
This point was made during Microsoft's press conference at E3 when a little girl came out onstage and began to play with her virtual tiger cub. Although the sequence seemed a little over-dramatic and scripted, what other device allows gamers to interact with virtual objects simply by using their hands? Imagine playing chess or constructing a virtual racetrack.
While it seems that most E3 attendees and viewers thought Nintendo had the best of show, Microsoft's Kinect showed the most promise on a hardware level, hands down.
