Carmack On VR Latency 94

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."

    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. []

    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.
