I think people are forgetting that this feature can be turned off. Nobody is forcing anyone to use it. It's for people who want to experience something different and innovative. Wii anyone?

it works for that guy in teh vid b/c he is riht next to it, that way it can read his suttle movement and expand them in game

how ever the farther away fromt eh camera you move teh hard it wil lbe to read little movement and the only way for it to register Is by making larger movement tat might require you to really crane your eyes left or right to still be able to see the screen


Not to mention I don’t know of a single person that can sit perfectly still (as in 0 % movement )

There will always be soft tremors moving thru your body and your head is very rarely ever at rest ( it’s a fact of life) so sitting across the room the camera will either have to be so sensitive that it will read every movement and exaggerate it or almost no movement thus making me have to do the majority of it

However this could be great and (VR like) if you combine it with a goggle system so that I look right, the camera reads that, and my goggle show that….win


Or you could move the camera closer to you

Bingo. It doesn't matter how far you are from the montior or TV but the distance from the camera. I already have used my Track IR 20 feet away from my HDTV when I'm playing IL2 on my HDTV instead of  my PC monitor. (my pc is 20 feet away from my HDTV).

 Now it is true Track IR does take a little getting used to because you move your head a lot more than you realize as well a small turn of your head means a much larger turn on screen. Now That I gotten used to Track IR with a game like IL-2 on the PC  I really miss this feature with the PS3 version of IL-2.

 P.S One  big plus is PS eye is a lot cheaper than a Track IR unit which is over $100.

FPS game with PSwand for your gun and head tracking for you to look around.

Just a shame FPS aren't as big on PS3 as on 360.

Personally I'm not crazy about Track IR when it comes to FPS since you are  trying to turn & aim with your mouse plus head movement. Unlike a plane or car, your character turn instantly with the movement of a mouse.

You could use heading tracking as a mouse substiute which was it purpose in the beginning for the handicap.

Eye tracking would track in much finer detail, and wouldn't require you to look off screen because the center would constantly be moving to the location of your eye's focus.

I just don't see this working, especially given the EyeToy's terrible accuracy dealing with colors and light as it is.

@Jaaau!
The EyeToy doesn't use Infrared technology as far as I knew. It is merely a simple 2D tracking camera with a microphone. The only way it can even track 3D space is by guessing that a "bigger" object in relative to it's location means it is moving closer, which is true, but with very weak color detection and lighting needing to be perfect, I don't see it working all that well. That's why Sony Motion REQUIRES those light balls on the end because without those, it couldn't track the things worth spit.

I think that is good enough for head tracking a la Track IR

I see a major problem with the video in OP. He is moving his entire head left or right, up or down. To see the image form a different angle. But he isn't turning his head. If your playing GT and you turn your head, you wont be looking at the screen. Going by the video, you will have to keep your head straight and move it physically 12 inchs right or left, up or down.

This is why 3 screens were designes and used for racing games. Because you physically need to turn your head, not move it left or right. Still the tech could be used for other stuff, I wonder why they cant do full body tracking with PSEYE then ?

I'll just wait for TGS for more info. about this feature, to see how will it works. That's the best thing I can do right now and TGS is couple of weeks from now.

 The first TrackIR (1-3) used only one IR point  which you could turn you head slightly to see all around your plane or car.  With only one point you can only have two directional axis. In this video  he used  two IR points. The newer Track IR models uses 3 IR points so you can have all 6-D axis.  With only one or two IR points you can't have all 6-D axis  so the programer must choose which axis will be used in the game/program. 

 In the Op video if the camera sees the two IR points move closer together (thus the player is moving back) the game zooms out. If the two point move farther apart then zooms in. If the points move to the right then the game view shifts to the right. if the points move to left then view shifts to the left. Now in this video because you are using only two IR points instead of three the program would have trouble to determined the difference between the player  turning  his head a little to the right from a player moving to the right and backwards at the same time.
