I've worn an Oculus Quest 2 on an airplane to watch 3d movies. It works fine. This article is way too deep of a dive on non-issues. * Sure, you don't get the full resolution. The apps typically put you in a virtual movie theatre and "waste" pixels on your environs. But people watch 720p content all the time! Would I want this to be my only media experience? No. Is it better than your tiny phone or cheap tablet on your tray table? Yes. * The 6dof tracking is totally off because the cameras can't see the fact that you're moving and you just end up shifting wildly. You can turn it off and go back to accelerometer-based head tracking and it works fine (modulo landing and takeoff, and in those regimes you just need to reset the viewport every so often). I would recommend you turn off 6dof before you get on the plane though; it's wild trying to do it on the plane.

I’ve worn a Sony glasstron to watch movies on a planes, back in the Stone Age, and given that DVD at 480p was the pinnacle of quality at the time, it also worked just fine — as long as I didn’t move my head.

> But people watch 720p content all the time! I had the same reaction, and the article only says that the effective resolution, accounting for their "pixels per degree", is something less than 1080p. Which sort of implies it is better than 720p...somewhere between the two. Plus whatever benefit blocking out the things around you in the plane has. I'd much rather hear some reviews of the experience from run of the mill people that don't have much experience with VR. I suppose the article does, though, at least set a reasonable expectations bar.

  My interpretation is that it is some sort of cognitive bias, which is very common: Because A is better than B, we start to think of B as not good, while in reality B is still good and A is just better. In particular A may only be marginally better, or only be better on paper, according to an irrelevant metric. I see this come up a lot in hardware discussions (Megapixels come to mind) and manufacturers love to jump on this effect.

Yep. I have the NReal Air's. I still prefer a TV when I'm chilling at home, but the NReals work great on planes.

    - RockRobotRock 3y ago
      The device needs to have a USB-c port with DP mode
    - SkyPuncher 3y ago
      The USB-c port you use them with needs to support video output. Not all USB-C ports support that. I also have them working (without audio) with my Playstation.

    Nope, they're essentially a general purpose portable monitor. They basically feel like a giant, 1080p projector screen. That's just in "dumb" mode. * They supposedly work well with Dex (Samsung/Android VR space) * They also have a desktop app called "Nebula" that can generate up to 3 virtual monitors. Resolution low for each monitor, but it's handy for having a bunch of different material in your view. * They can also do 3D side-by-side mode.

Could the Vision pro just track you based on your environment rather than the accelerometer while on a plane? That would prevent any kind of drift. If that R1 chips is as fast as they say then that doesn’t seem unreasonable.
- numbsafari 3y ago
  Based on what they have said in interviews, I have a feeling that is exactly what they are doing. My guess is that they combine a number of signals to do the tracking, and when those signals start to disagree too much they've prioritized some signals over others. That could include things like how your eyes are tracking and other physiological signals, not just the accelerometer and various cameras.

  This is what the Meta and Windows MR headsets do as well, it's not even that intensive.
- smoldesu 3y ago
  Most inside-out headsets like the Quest and PSVR already do this. It hardly has anything to do with system power, and is more about resolving contradictory sensor readings.

>But people watch 720p content all the time! I'll do you one better. My nephew was going to a summer camp that didn't allow the kids to bring phones or tablets. He was allowed to bring an MP3 player, tho. So I downscaled a copy of Into the Spiderverse to 432x240 (his iPod Nano's native resolution). I left the bitrate quite high (1600kps) and it looks absolutely great. Even stretched out on a full sized ipad, it's completely watchable.

    Maybe he will get caught as part of the summer camp experience. I think transistor radios at summer camp were thought to ruin the experience.

    As a summer camp alumnus myself, I can assure you that finding clever ways to circumvent camp rules is itself a cherished camper tradition.

    Sometimes a little bit of comfort makes being away from home easier on kids and makes the summer camp experience a positive one.

  I've said this before, but people process resolutions wrong. Resolutions are not a promise of a minimum of quality, they are a maximum. High quality pixels at lower resolution can stand up to more processing for upscaling than garbage ones. A resolution tells when you'll top out because you've got near-100% fidelity for each one. I have a bit of astigmatism, but I still don't wear glasses as a routine thing, and when I watch good DVDs on my 60" TV from about 8 feet away, it's fairly rare for me to be that upset by the video quality. Even after I suck some out downsampling into mp4, it's still rare for me to actively notice. DVD encoders are fairly good now. At this point I don't care at all if something advertises a "4K" stream because I know that it's still likely to be not all that good. Tell me the bitrate of your stream, that's what I want to know. (Assuming the use of a modern codec and quality encoder.) I can get a "4K" stream with hundreds of kilobits per second. The encoder will be crying because of the shoddy job you're making it do and the decoder will look at you like you're on crack, but by golly, 4K's worth of pixels will indeed be shoveled onto the screen.

> The 6dof tracking is totally off because the cameras can't see the fact that you're moving and you just end up shifting wildly Why? I don't get this. As long as the plane is moving at a constant speed it should be no different from sitting in a stationary room right? Unless there's like turbulence or something I guess?

- Retric 3y ago
  Resolution is only half the story. High bit rate 720p > Netflix levels of 4k video compression. Downsampling compressed 4k video to 720p probably looks quite good as long as they don’t then compress the output.

As a fairly tall person, working on a laptop or tablet on a plane has become a literal pain in the neck. I don't know if it's that the seats are closer, the tray tables are lower, or maybe I'm just getting old. This seems like a much more pleasant experience.
- smoldesu 3y ago
  Some nights I'll wear my headset in bed for this reason. I've got a TV in my room, but with my Quest I can lay back however I want and still get an IMAX display in front of me. Not sure if I'd be desperate enough to try it on a plane (the stereoscopy would probably make me sick), but as a viewing experience it's phenomenal. The OLED panel on the original Quest is a godsend for movie watching, and when streaming over DNLA I can get 3-4 hours of battery life.
  - crazygringo 3y ago
    Yup I do the same. The key is an app that doesn't use the "movie theater" gimmick but just gives you a screen you can resize arbitrarily and move in space to vertically above your head. It truly is a glorious viewing experience, and if you make the screen large enough you effectively get full 1080p detail.
- bick_nyers 3y ago
  For me it's how close the seats are, you have to hold your hands in close to your body to type on a keyboard, and you don't have the room to tilt the screen back for a good viewing angle. Sometimes I've found resting the laptop in my lap/knees along the screen hinge (so it makes a 45 degree angle with my thigh) to be the most usable. This requires you to pull your shoulders/elbows back however so you usually can't do it if you have someone you don't know sitting next to you. I have strongly debated bringing my Quest 2 onto a plane and using a wireless keyboard to program with, I think the ergonomics would work out much better when flying coach.

Lower video resolution also feels like a decent tradeoff for a few reasons: - Thanks to the headset's optics, you're staring at a point in space ~5ft in front of you instead of a couple feet tops which cuts down eye strain - It's private, so you don't feel like people are watching over your shoulder - On international or redeye flights, you're not keeping everybody up with the light spewing from your tablet/phone

  > On international or redeye flights, you're not keeping everybody up with the light spewing from your tablet/phone On almost every international overnight flight I've been on people watch movies and TV on seat back monitors at all times. For people who need absolute darkness the airline usually provides an eye mask.
smachiz 3y ago
Agree completely. The author also suggests that you don't want "see through" mode coming on everytime someone walks by, but that's exactly what I want. I don't want to be in a public area, even a plane, unaware of my surroundings. If I'm watching on a 7" screen on a seatback, I still have peripheral vision. I want to maintain that. I want to see on the area that isn't the screen, I just want something bigger than 7", and the ability to do things besides just watch movies/TV (like, my own content or games....). Basically, this is clickbait.

Do you typically have issues with nausea? It just seems to me like many people might struggle with VR on a plane given that planes and VR can each on their own cause people to vomit, and not only would you be using both at the same time, but they would actually impact each other because the plane has turbulence which would impact accelerometers but not cameras. I have no idea how this would all work out in the end. Perhaps it wouldn't be as bad as one might think.
- pxx 3y ago
  No nausea issues with this setup for me at least. I'd say my VR stamina is probably average-ish? E.g. I use blink long-distance movement in Alyx and Red Matter because otherwise I get a bit dizzy, but otherwise my stamina is limited by headset comfort and battery. Yeah the important thing is to turn off the cameras. It'd be a vomit inducer otherwise.
