You know, first of all you don't pay only $400 or $500. You have to count the online paywall for both consoles. If you buy a PS 4 with $5 per month for online and you have the console for 5 years you payed ultimately $700  for it.

You also don't get a game with the standard bundle....another $60. Now we are at $760, then you want Camera maybe because it isn't bundled with the PS4, another $60  = $820. If I buy a Wii U with 300 $ I have 1-2 games, depends on the bundle. And also every feature from the beginning.

And almost everyone has/had a Wii at some point. If you want to play with other people they can bring a controller with them o you have one yourself. Also you can play every freaking Wii Game. You don't have that on the other consoles. Oh and the freaking remote play is also included in every bundle. The range isn't comparable but is has no lag at all. And if you wanna have that feature on PS 4 you need online features again and a vita (and not many people have them. +200 $. Or maybe $150-$175, depends on how they price the combined PS4/Vita bundle. So please do some research before saying Wii U price for it's value is 100 $ too expensive. 32 GB of memory isn't a excuse, depending on the game you can get as many games on it like the 40-50 gb games on a 500 GB HDD in the PS4.

3D is perceived with 4 bits of information: motion parallax, focus, convergence, and visual clues. Any 2D picture covers the last one, because our brains see the shadows, reflections, faces, etc. and understand the scene should be 3D. However 99% of the time this isn't enough to trick us into thinking it is 3D.

3D movies and the 3DS have the visual clues, but they also have convergence. The viewer's eyes converge on a 3D point in space rather than on the 2D screen. This is by far the strongest 3D clue our brain works with. Even on its own our brain perfectly perceives the image as 3D, as shown with magic eye pictures.

Head tracking is giving the visual clues ad the motion parallax, but if it lacks 3D convergence than 90% of the time the brain still perceives it as 2D. Plus the effect only works while the viewer is in motion. Unless you plan to bob your head back and fourth, it's just not good enough on its own.

In videos of the effect however, our brains only go off of visual clues. Because we are so used to seeing 3D scenes represented as 2D pictures, our brain just assumes the screen in head tracking videos would be 3D in real life. In the youtube video all of the visual clues say it's 3D, so we assume in real life it'd work that way. It doesn't. It's actually a very similar effect to viewing pictures of 3D chalk drawings.

All the visual clues in that picture make it almost impossible to know that most of it is flat, not 2D. Looking at the picture it "feels" 3D even, or at least if you imagine this scene in your head, it'd be 3D. Viewing it in real life, even from this perspective, the illusion would be much worse. Convergence and focus would instantly tell you it's 2D, while when viewing a picture your brain ignores those. The same is happening in the head tracking video and every other one trying to look 3D in that matter.

Focus is by far the most ignored 3D bit but it's still pretty valuable. There's only one 3D screen I know of that actually uses it.

You have not emty you head.. You are still trapped in the same ideea..

No.. you don't have to move your head at all to get the effect.. becurse the image  will change for you.. arcording to where you look at it.. meaning if you hold your head perfectly still.. and use wiimote/ nunchuc to walk..  the picture above (or 3d game on a 2d screen) will still be perfect 3d from that angel and perspectiv.. (change  real time) and that is not some trick with the eyes.. it's the game that make that efect ..

And funny how many saying VR are shit.. and even gimmick.. when there are som many different VR set on the way.. from the biggest player in the industry..

It's already confirmed.....

I really don't think I need to empty my head.

There are only three things that I'd say I'm truly qualified on. Game development (I'm a game developer), twisty puzzles(I hold many world records on Rubik's cubes. Even nerdier than video games but I love them), and 3D/VR(I started designing light field displays when I was 8 or so. Built my first working prototype at 13)

Not trying to impress you, but just express that I know what I'm talking about. Have you experienced head tracking for a 3D effect? It's certainly cool, but no it's not even close to feeling 3D compared to stereoscopic 3D.
