Dr Richard Marks – who many will know as being the creator of Sony‘s PlayStation Move technology – has got in a nice dig at motion control rival Kinect, saying that Microsoft’s decision to have no controller at all on the product could actually end up being quite “limiting”.

The Kinect doesn’t look too limited here anyway.

Speaking T3, Marks claimed that Sony had considered doing away with the controller in the same way that Kinect does, but that ultimately it did not allow enough freedom for the gamer. “I think it depends if you believe that controller-less is necessarily better which I don’t believe,” said Marks.

Ahead of the inevitable Christmas battle between the pair – just wait until late October or early November and the TV campaigns will be relentless – Marks has ramped up the pressure on the rival to his baby.

“I created the technology for EyeToy which we made a controller-less device and it was really neat and it enabled new things but it is not the end-all, be-all in control,” he said. “We entered limits with that and I think without a controller you run into limits of what you can enable.

“You can do things like track the whole body, you can have dancing and exercise but a lot of the core gameplay ideas that we want to see happen and want to enable just weren’t possible with only a camera. We would have done that, we look at as much as we could do with just a camera but it wasn’t the right choice we felt,” he added

Is he right? I dunno, those who have tried the Kinect say that it is a markedly different proposition from the main motion control kingpin, the Wii. Perhaps this novelty value alone will help it push past the Nintendo item this Christmas as well as Sony’s more traditional-looking Move. Maybe we’re wrong but Marks’ comments have the air of someone trying to win a PR battle before the sales war begins.
