Last week Sony Move engineer Anton Mikhailov was quoted saying a Move-powered Lightsaber game would be "damn better than Kinect's". But he's not done bashing the MS motion controller. No, he wants more.
This time he says Kinect's tech is "not quite up to spec" and is "mostly technological problems".
"We're not necessarily against Kinect or against depth cameras, it's just we feel like Move has more applicability across more genres so it fits better with what we try to do," he told Videogamer.
"Also I think the tech is a bit, not so much immature, but not quite up to spec in what we think. Like the PlayStation Eye camera runs at 60 frames per second so it can track you very quickly whereas the Kinect and other depth camera are only 30 frames per second. So they are more suited for slower motions.
"Dancing is still kind of okay and then the yoga stuff that they were doing, it fits that very well, whereas if you want to do quick punches it's harder to do that just because you can't see the player as quickly. And there's also more latency, things like that. So you know, it's not a particularly sexy result, it's just mostly technological problems."
He goes on "We thought that they were just minor, well not so much minor. Marketing-wise they're minor tech problems, technologically-wise they're quite big.
"The fact that it runs at 30 frames per second instead of 60, that's a common problem with all those cameras. It's actually hard to fix because you have a lot of data to transport. Sort of working with that image is expensive computationally-wise. I think they quoted something like 10-15 per cent of the Xbox resources, plus like 50 megs of memory or something like that.
Of course, Move doesn't have that issue. "The Move takes less than 1%, and like 1 megabyte," he points out. "So, you know, that's just a bunch of numbers but to developers that means [games] like Killzone 3 can just put in Move and not have to worry about it, whereas something like Kinect you have to make significant game changes to actually fit that into your game."
