What VR could, should, and almost certainly will be within two years
Valve has been collaborating with Oculus for some time now and not long ago they helped them build their latest Crystal Cove Prototype. Although they see the CC prototype as a step in the right direction, they believe that we still have some way to go before the age of AR is upon us. At least one more year to be exact. They've built their own state of the art costly prototype to showcase what is to come and apparently it's blowing people's minds.
David Hensley of Tripwire was particularly hyperbolic, and said that going back to his Oculus Rift would be like switching from an Xbox to an 8-bit Nintendo. "Valve’s VR demo at SteamDevDays felt like being in a lucid dream state and very much like a holo deck."
Johnathan Blow (developer of Braid & The Witness) explains that he was skeptical of VR technology based on what he'd seen so far but that Valve turned him around; "It's so much better than anything else I had used that I was instantly very excited by it." "Right away I could see games you might design for this system that had been impossible before."
One of Valve's brainiacs, Michael Abrash regularly spreads words of wisdom from his blog; Ramblings in Valve Time and he did the same at the Steam Dev Days event where he delivered a very interesting talk on the future of VR in which he outlined the somewhat magical experience of presence in VR and pointed to 2015 as the year that it's likely to be achieved on consumer devices.
"Once hardware that supports presence ships, we think it has the potential to cause a sea change in the entertainment industry. Not only could VR rapidly evolve into a major platform, but it could actually tip the balance of the entire industry from traditional media toward computer entertainment."
"Presence is hard to quantify, but our demos have shown that it is a very real and compelling phenomenon, one that hooks far deeper into the perceptual system than anything that’s come before, and it’s why we’re so excited about the future of VR. It’s our belief that great VR will be built on presence, because it engages you at a deeper, more visceral level than any other form of entertainment, and can only be experienced in VR. "
"Presence requires a wide field of view, adequate resolution, low pixel persistence, a high enough refresh rate, global display, specialized optics, rock solid tracking, low latency and fine tuned calibration. I want to emphasize that presence is not a property of any one of these elements; it’s a property that emerges when all of the elements are good enough. If the optics aren’t calibrated perfectly, then the scene will warp as you turn your head no matter how good everything else is. Likewise, no amount of fidelity will convince your visual system that a virtual scene is real if latency is too high. Presence can’t be induced if even one of the key elements is subpar. It's worth noting that inducing presence reduces motion sickness because what your eyes see will more closely respond with what your vestibular system reports.
According to Abrash presence requires the following minimum specs;
• 20 ms motion-to-last-photon latency
• 3 ms pixel persistence
• 95 Hz refresh
• 110-degree FOV
• 1k x 1k resolution per eye
• High quality, well calibrated optics
• Tracking
- millimeter accurate resolution translation
- quarter degree accurate rotation
- volume of 2 meters cubed
"This head-mounted display would support a powerful sense of presence and would have an excellent shot at widespread adoption. VR can certainly get much better yet down the road, but that’ll require time and major hardware R&D. In contrast, we believe everything on this slide is doable with relatively minor tweaks of existing technology; no breakthroughs or miracles are needed, just solid engineering."
Still, it's important to note these are the minimum specs to achieve presence. When these arrive in 2015 they will enable us to step into other worlds but there will still be A LOT of room for further improvement. "For one thing, presence would benefit from every one of the key elements getting better than what’s in our prototypes. We could literally use up to 100 times as many pixels, and a wider field of view, lower latency, and all the rest would also improve the experience; the optics in particular are far from optimal. Also getting per user lens positioning right is a challenge. As I mentioned, we think we’re close on head tracking, but we don’t have a shippable solution yet, and then there’s eye tracking, which could greatly enhance presence but is nowhere near solved. Going to a wireless connection and eliminating the tether would
be a big plus."
