Sony’s research and design boss, Dr. Richard Marks, has decided to step forward and confess that not only is PlayStation’s own EyeToy a limited technology (he would know), but that Microsoft’s Kinect is limited by the same reasoning as well. Considering Marks created the EyeToy and stands by the fact that it is a “neat” device, he also understand that the lack of a controller is something gamers won’t be able to overlook in the long run and will limit the enjoyment that Kinect or EyeToy tries to deliver on its own.

Speaking with T3, Marks explains that he thinks “it depends if you believe that controller-less is necessarily better which I don’t believe. 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.”

He added: “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.”

This isn’t the first time Marks has spoken out against the camera-technology. Last week, quotes were released sharing that Marks didn’t believe hands-free controls were viable. Regardless of how all of this plays out, it will be interested to see if both Move and Kinect end up as dust collectors like most Wii consoles or if they’ll be used.
