Can Kinect Only Recognize Two Players Per System?

If so, Why is Sega Touting 4x Local Multiplayer for Free Riders?

Until gamers can try it for themselves, it’s unclear with Microsoft’s tinkering how many players will legitimately be able to simultaneously take part in games enabled by Kinect, the company’s new peripheral out in November.  But in an interview published by Joystiq with the company behind Kinect’s core technology, it may not be many.

PrimeSense made the raw pieces, and they in turn licensed the tech to Microsoft.  Admitting that much of the legwork and processing is handled by MS’s own software, PrimeSense reps told Joystiq’s Mike Schramm that the chip embedded within the camera can only process two people at a time:

PrimeSense reps also told me that the camera can “see” any number of people on the screen — you can fit as many people in that camera as possible, and the computer will see all of them and can even recognize them as human shapes. But it can only run calculations on two people at a time, just because the processing power required to track all of the body’s locations and movements is so great. During our testing with the device, a person moving in front of the camera was able to “steal focus,” but the computer can also be told through gestures to keep focus on a certain person.

That acknowledgment is important for two reasons.  First, it contradicts words Microsoft’s Alex Kipman, project director on what was then Project Natal, told Eurogamer in a June 2009 interview.  Back then, Kipman outlined multiple control possibilities, across multiple players:

We can track up to four players in the same way we track controllers. Each individual player will be able to choose – do I want to bind with a controller, or do I want to bind with my body, or do I want to bind with both?

There’s reason for Sonic fans to be concerned, too.  On Friday, we reported a claim from the official product listing for Sonic Free Riders that touted local multiplayer for up to four people.  But if the core technology can realistically support only two, how will additions pan out?  Is that why SFR demos on the E3 show floor were with only two people at best–and only performed by Sega staff?

If Kinect can’t handle more than two players, it may not just be a case of false advertising on both Microsoft and Sega’s part.  There may also be supporters of both the system and of Sonic Free Riders venting frustration when large scale multiplayer bouts go awry.  It is possible Microsoft’s added technology have alleviated concerns, but until we hear something more concrete, you have been warned.  The presence of Sonic Free Riders at future conventions open to the public–or lack thereof–may be  telltale signs of whether both SFR and Kinect itself are ready for prime time.
