Carmack On VR Latency
An anonymous reader writes "For a while now, John Carmack has been pushing to bring virtual reality technology back to the gaming world. VR was largely abandoned over a decade ago when it became apparent that the hardware just wasn't ready to support it. In 2013, things are different; cheap displays with a high pixel density and powerful processors designed for small systems are making virtual reality a... reality. One of the last obstacles to be conquered is latency — the delay between moving your head and seeing your perspective change in the virtual world. In a lengthy and highly-technical post at #AltDevBlogADay, Carmack has outlined a number of strategies for mitigating and reducing latency. With information and experience like this being shared with the game development community at large, it shouldn't be long until VR makes a permanent place for itself in our gaming lives."
.... I can't help thinking this
Surely any dedicated gamer would see the value in simply injecting a thickening agent into the endolymph of the Vestibular system. With careful dose control, that should induce a matching lag in the perception of motion, thus providing a highly realistic experience!

Stanford has an elaborate VR lab. The system is 120FPS, and the lag is low, but I'm not sure how low. There's full motion tracking of the subject in a 20 foot by 20 foot space. They have public tours every Friday. Sign up and try high-end VR.
This isn't a graphics lab. It's a psychology lab. Some of the results are scary. They've had kids go through a VR experience of swimming with sharks. A few weeks later, the kids are asked about it, and a sizable fraction of them believe they really did it, adding details that were not in the sim like what they ate while visiting the sharks.
They're always running psychology experiments, and looking for volunteers. Pays $15/hr.
How can they not talk about Carmack's chosen one? This seems to be the best hope for affordable VR for the masses.

Oh, yeah. Michael Abrash did this two months ago.

Google Glass doesn't have anything to do with VR. You are confusing it with Augmented Reality.

I remember when everyone suddenly got excited about virtual reality in the early 1990s. Of course, back then it was more the concept and the possibilities that triggered peoples' imaginations- actual VR systems and games did exist at that time, but were never really widespread, probably due to the limitations and cost of the then-current technology and the fact it was essentially a novelty.
:-O
One commentator, however, said something that has stuck with me ever since. I can't remember the exact wording, but it was along the lines of...
"Eventually the current fad for Virtual Reality will pass, and everyone will forget about it. Then one day you'll look around you and realise that it's everywhere."
(*) If you remember it too, then yes- it really *was* that long ago
"Slashdot - News and Chat Sites Deviant". (Click "homepage" link above for details).
Numerous studies showed that extended use of VR could cause severe problems, namely permanent lazy eye (loss of depth perception). I believe it was Nintendo that dropped a VR product because of their own studies (I'm too tired to go look for the data at the moment). Government studies also found this to be true, so working in VR in Government jobs is restricted (or was when I was there) to 8 hours per week.
More studies need to be done to determine safe levels, and most importantly people should be made aware of the potential risks to health. Currently there are no warnings that I'm aware of and most people have no knowledge of the studies.
-The wise argue that there are few absolutes, the fool argues that there are no probabilities.
"Tick", hyphen, "tack"? Your 3D printed clock sounds like junk.
But his breath is minty fresh.
Actually according to Wikipedia the first red/green anaglyph film was shown in 1922 for an audience in NYC. man I knew that shit was old but not THAT damned old.
And as much as I hate to admit it, but being in computer retail as long as i have I know this will end up being the case, know what you need to get VR the big thing again? Porn, that's what. people wanted burners "To back up my pictures" (bullshit, porn) and they got big hard drive "To store my pictures" (A TB of pictures? bullshit its for porn) and if they come out with VR porn I have no damned doubt I'll be selling VR units to people who'll say "So I can see my pictures in virtual reality" (Bullshit, I've seen your family and they don't even look good in 2D, its for porn).
If there is one thing I've learned its not only the Internet that was made for porn, everything from VCRs to big fat HDDs are all needed for porn. Porn, its what drives technology today for a better smuttier tomorrow.
ACs don't waste your time replying, your posts are never seen by me.
