Yeah, but just to play devil's advocate for a mo, not everyone's idea of FUN is the same. I've yet to find many films where my enjoyment was increased by the addition of 3D
Comparing a 3D TV with immersive VR are as comparable as:
Staring at a Mona Lisa vs Watching a Blu-Ray
Do you even know how VR affects your state of mind when you are immersed? The sense of "presence" allows you all the feelings you get from actually travelling to that place.
For instance. If you are falling down in VR, you will actually feel like you are falling down - you've had the dreams where you fall, so you know you can experience the sensation without actually doing it.
If you're standing near a huge castle, you will actually think you are there, and you will be in awe at the size of it.
Seeing mountains in the distance, makes you actually think they are in the distance. Seeing a cockpit around your body, makes you think you are in fact surrounded by this cockpit.
It doesn't even fade away the more you use it. The sense of vertigo from standing at a ledge doesn't fade one bit, regardless of how many times you've tried it.
All this happens because of a trick of the mind called "presence", which overrides your conscious and rational mental faculties. The "primal brain" which governs your sense of presence are much older parts of the brain, older in terms of evolution. So it's like the BIOS (when you boot up your computer). If you disable a hard drive in the BIOS, it doesn't matter what a higher operating system like Windows tries to do. If BIOS is told that the hard drive is disconnected, Windows won't even have a chance at booting up. Similarly, if your brain's temporal lobe is convinced (by the eyes) that it is falling, it will overrule your brain's higher systems (the rational parts). So you will be rationally aware of the illusion going on, but you won't be able to affect how the
visual cortex ->
temporal lobe -> goes directly to your
limbic system, and makes you fearful, sweat and feel like you are falling.
That's my way of explaining how a sense of "presence", however irrational, can completely convince your body. Even though your rational mind knows it's just a trick, because you're wearing the VR headset.
In order to achieve Presence, you need to fulfill certain criteria. And you can't break even one of these criteria:
Michael Abrash gave a talk on VR at Steam Dev Days in 2014. According the VR research team at Valve, all of the following are needed to establish presence.
- A wide field of view (80 degrees or better)
- Adequate resolution (1080p or better)
- Low pixel persistence (3 ms or less)
- A high enough refresh rate (>60Hz, 95Hz is enough but less may be adequate)
- Global display where all pixels are illuminated simultaneously (rolling display may work with eye tracking.)
- Optics (at most two lenses per eye with trade-offs, ideal optics not practical using current technology)
- Optical calibration
- Rock-solid tracking - translation with millimeter accuracy or better, orientation with quarter degree accuracy or better, and volume of 1.5 meter or more on a side
- Low latency (20 ms motion to last photon, 25 ms may be good enough)
So please, try to get some knowledge on the subject before comparing it to a 3D TV
