When the PlayStation 4 launches this November, the PlayStation Eye camera will enable you to sign into the console using just your face. Unlike its Microsoft counterpart, Kinect, the Eye won't allow much more control of the system. At least not initially. "At the time of launch, first the face recognition is for the purpose of logging in," SVP and Division President of Business Division 1 at Sony Computer Entertainment Masayasu Ito told Engadget in an interview this afternoon.

Beyond face recognition for log in -- something Sony's still not shown to the press or public -- PS4 users with an Eye will also be able to use voice "from the game page." Ito said, "Game titles could be called in and then the game could start." But in the future, Ito said the PS4's camera will go further. There's no voice or gesture command in the UI beyond what's described above, but he foresees more in-game use. "That's as far as it goes, but continuous updates, it can go deeper. Make it with greater depth. With face recognition, we think about how that could be used in the context of the game," he said. He sadly wouldn't go further, but demos like The Playroom -- a game that's included on the PS4 at launch -- offer an example of how the Eye will work in games. As for more UI control, well, we're hopeful that that's part of the "continuous updates" Ito promised.

That's fine as far as it goes, but the real advantage of Kinect is every Xb one will have one. So it doesn't matter what functionality Sony builds into the PS Eye it's small user base compared to total PS4 user base will always hold it back. Perhaps PS5 will have an Eye packed in from launch, though perhaps by then the next innovation in controls will be something different and Sony won't pack that in with every console either.

One advantage that I believe MS has in this area is that they have built the X1 with Kinect as the means of doing voice navigation. The X1 has dedicated audio hardware chips to do all that processing without out taxing the CPU. From what we have seen so far for the PS4, Sony does not have this type of setup. This could mean that the CPU would need to do a lot of work and if this is done in game could have an effect on performance.

Another area that MS has a head-start is in the voice recognition. MS has been doing this for a long time even before you toss in Kinect. Voice recognition is a touchy technology when you do international and even local with a lot of different accents.

I believe there will definitely be things the PSeye will be able to do because it has a camera and Audio chip array like Kinect. Without the depth sensor, true mapping of body and environments will not be something it can do. The PSeye will be very dependent on lighting within your home which I can tell you from my experience is something that breaks both the PSeye and the first Kinect.

It should be interesting to see what Sony does with the 2 cameras. Will we see some 3D type of camera features. I am hoping for something unique to get me to purchase the PSeye again.

Don't care for the eye.

It's fine if they add some shortcuts with voice and face recognition, as long as the UI has been fully optimized for controller use. Voice recognition is not for me.

Is Move still supported on the ps4? My 4 year old is currently loving Puppeteer with the move. That light ball on the end of a stick with buttons. 4 year olds dream toy.

QUANTIC DREAM!

Just interested, why is voice not for you.  Do you have bad experience with voice commands or you just do not like talking to your devices.  The only reason I am asking is that I can see voice being much faster than picking up a controller and navigating to something instead of just saying "PS4 Play God of War".

I feel like with their similar architectures on the systems, they can easily port these features if one feature really catches on.  If a game uses some crazy Kinect trick and users go wow it can easily be ported at a little less resolution and fluidly than Kinect.  It's obviously up to MS first party though because third parties aren't going to screw over Sony like that.  That would be like if this gen a bunch of them used analog face button recognition and made it an integral feature therefore gimping the Xbox version.

Just started playing Pupeteer. Haven't used the 3D or the Move controller as of yet. Is it worth trying out the Move controls?

Still nothing that interests me beyond possibly using the Move in FPS games. Will it be three or four seconds quicker to use voice commands? Maybe, but it's not like I'm sitting there going, "Oh my GOD, it's so hard to navigate to my game!"
