Well, I don't have the money now, but Q4 '22 is a while away. So this is the first newsletter I've ever signed up for.

Any text thoughts on text inputs while mobile? I've actually got a split keyboard like you show in use while standing, but that looks a little janky. Maybe we all need to learn how to use twiddlers.

This looks like a decent deal looking deeper into it. Things that weren't obvious on first pass: (1) The VR specs are much higher than consumer level. I suspect this is what makes it reasonable to read text on it. The comparison headset is this: https://varjo.com/products/aero/ (They named it, but didn't google it) (2) They said "VR Computer" but don't define the term. They mean that it's a full PC with a headset ins…

> * Is there some useful interactions between 3D visualization and high-quality small-text rendering? If you have good VR/3D developer stories, then this can work.* Yes, I want to see a CAD application where the user is looking at a complex CAD model in 3D, with labeled parts and everything, and usefully interacting with it. Typing commands, grabbing and turning the model, etc.

That would be so, so cool. I don't see this happening for a while unless a CAD vendor works with us but definitely where I see this tech.

Man, what has HAPPENED to this place? I'm the biggest curmudgeon in the room, I'll have six feet of dirt on my face before I agree to use this daily, but damn, folks, this IS cool. Everyone complains about boring stagnating consumer tech, locked-down hardware, and Mark Zuckerberg making a real go at personally stalking every single person on the planet - this is the _exact opposite of that_.

The top 10+ subthreads are all positive - I think I had to go all the way to #18 to find a negative one. You may be falling prey to the contrarian dynamic: https://hn.algolia.com/?dateRange=all&page=0&prefix=true&sor...

You may well be right - and, to the point of your explanations about the dynamic, the sentiment definitely seems to have shifted - which is great!

I'm a bit torn, as on the one hand, I'm squarely in the target demo and appreciate the huge amount of work that has gone into the project, and the PPD is really exciting. (back in 2015 I actually started building my own VR workspace software https://www.youtube.com/watch?v=jNtZmCDyEyU with an Oculus DK2 but shelved it for other projects waiting for better HMD hardware that never arrived). But sadly, I fear that if I ordered a Simula, it might end up years late, half-baked, and sitting on the shelf like my LibreM 5 and many other open source hardware projects I've backed. (Also the ergonomics of the HMD really makes me a iffy on whether it can be worn comfortably for extended periods.)

I also think it's also somewhat bad timing, since HMD hardware releases are finally picking up. Panasonic's MeganeX, which uses 2560x2560 120Hz micro-OLEDs, is finally being released in the spring for <$1000 after being first shown 2 years ago (and there seem to be lots of similar micro-OLED HMDs in the pipeline from various Chinese manufacturers). Also, even though the PPD is much lower, there's stuff like the Lynx R1 coming out shortly that will also have full OpenXR support, is committed to privacy and staying independent, and has number of things that makes it more useful as a platform for all-day wear and hacking on: an ultra-thin flip-up form factor, 6DoF SLAM, UltraLeap hand tracking, eye tracking, and has already-working overlay AR (w/ 20ms camera-eye pipeline).

Thanks for the kind reply—I always brace myself when posting like that!

When I visited this thread 2h ago, the top subthread was negative.

Definitely some kind of weird dynamic going on...

I would highly discourage including a keyboard or mouse. If you are already spending $2700 on a VR computer I suspect you already have a keyboard or mouse you prefer or want to invest in a setup of your choice. No point in creating eWaste to drive home the point that this is a computer. And to that point you say that they need to emphasize that it is a computer and not just another headset (to the point of saying included a keyboard and mouse), but then bring up their use of terminal windows in their marketing (I agree though they should show other things as you suggested)?

Two of your points in your comment seem to be lambasting the fact SimulaVR aren't advertising towards the lowest common denominator of people buying tech. It is a $2700 computer and display. Who exactly, that would ever actually purchase this device, would not understand it is a computer (or that it can come with one if you aren't doing stand alone), or not realize that if it can be used in a coffee shop it can be used in a home office?

I think this is really cool, however I view VR headsets like monitors. I want them light, cool, and relocatable. I would imagine it would be cheaper to have this as two units. The headset, and "the box". The box does all the fun stuff and sends it wirelessly to the headset. Use a hardware compressor/decompress and a wifi 6e chip. Really that's all I want, a headset that is comfy, stays cool, great lenses, and can be…

Isn't the reason why this is typically not done that VR giving a good experience is very low-latency-dependent, and it's very hard to make wireless connections have an ultra-low latency?

This is all true, but it also doesn't mean the that the current high price was the only possible approach. I see decisions made in the design that don't look great from cost-benefit standpoint. For example, this is being marketed mainly as a productivity tool. Wireless is certainly important for gaming when you are moving around in your environment, but people using this are primarily going to be in a stationary posi…

It doesn't make upgrading impossible. The compute pack is detachable, replacable, and can even function independently. The benefit is pretty crucial: friction. If you have a tethered VR headset, the amount of work you need to do to set it up is insane. Especially with lower-level software like Simula.

>It doesn't make upgrading impossible. The compute pack is... replacable

It is only replaceable and upgradable if this company sells these compute modules separately. There is no discussion I saw on that website that they are committing to do this and there is no guarantee they will be around to still sell you one in the future. Even if they do, you are locked into their ecosystem.

>The benefit is pretty crucial: friction. If you have a tethered VR headset, the amount of work you need to do to set it up is insane.

I have never used a VR device on Linux and maybe the work involved there would be truly "insane", but I have used a few on Windows and they are basically completely plug and play after you install the software. Although even with the work involved, this seems to be an enthusiast device aimed at techies. If these customers are looking for a frictionless experience, they probably wouldn't be daily driving a Linux machine in the first place.
