Sony's R&D wizard Dr. Richard Marks has two impressive entries on his resume: Creating the PlayStation EyeToy motion controls and the upcoming PlayStation Move motion controls. And he thinks controller-less controls are "limited".

"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, we entered limits with that and I think without a controller you run into limits of what you can enable," Dr. Marks tells T3 magazine.


"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," says Dr. Marks. "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."

The PlayStation Move is going head-to-head against Microsoft's controller-free Kinect motion control system later this year.
