I would assume that move uses only gyro (IMU) data to determine its pose and uses tracking for position only. Lighthouse can also do that (for stuff with a gyro - which the HMD and controllers have), but it's only used as a fallback.

There are workarounds for this, primarily symbolic links/junctions. Oculus should be posting a support article about how to use these.
It is pretty stupid though that they don't support selecting a drive at launch.

The syncing part was very useful information for advising others on placement. Anybody not placing these things up high will have to use a sync cable even if they're technically within LoS. Placing a body between them, even if momentarily, is sure to break the sync.
Actually, that doesn't seem to happen:
He even goes into more detail in the same thread on the exact scenario you are proposing (someone moving between the lighthouses). As long as you have something somewhat reflective (like a white wall) enclosing your VR space, it still works. Of course, ensuring direct LoS is still best, and presumably the most resilient.
Vive and psvr use completely opposite systems for tracking, so it would probably be better to compare to rift/touch. I'm not sure how many points that system needs for a lock.
Also the stereo camera of psvr certainly helps.
When buying a $600 piece of hardware, I don't expect to have to implement a workaround.
IMUs do the vast majority of tracking for all 3 major VR systems. External tracking is only used to correct sensor error (drift). That's why external tracking updates at a much lower rate (e.g. 60fps camera, 60hz laser), vs ~1000hz for IMUs
1. Directory junctions. Yeah, they are somewhat cumbersome on a game by game basis. - hopefully there will be an Oculus Games folder or something like that to junction to another drive. Then the only potential issue is when a game installs and checks to make sure there's enough free space.
2. One of the Oculus employees posted on their official forum at one point confirming that a DisplayPort -> HDMI adapter worked just fine for the Rift. I'm guessing they won't be supported "officially" but they will work. My PC outputs to a TV (well, receiver -> TV anyway) that necessitates HDMI. I may upgrade to to a 4k display this year too, and the adapter I have won't support HDMI 2.0, so using the adapter for the TV is not a good solution long-term.
Why they didn't use a DisplayPort connection to begin with is beyond me. I'm guessing nearly all the cards that meet their requirements are limited to one HDMI port but have more than one DisplayPort.
Edit: I type too slow.
No one is going to disagree with you there.

I saw the bounce part, but I'm hesitant to recommend that somebody actually rely on it. I wouldn't feel confident in telling a prospective buyer "Hey, if you have white walls, you're set!" I prefer to err on the side of caution. Better to assume you'll need the cable first, and then have a pleasant surprise if you don't.
Thanks for the information. Much appreciated!
I really don't like the option of using Directory Junctions. But, i'm open.
How would this work as a matter of interest? If items are in the 'Oculus Store' and you browse it similar to something like Steam, how would you setup the directory junction?
Well yes, in order to correct error it has to know what the error is.
Constellation and lighthouse update at lower than the refresh rate of the displays in the HMDs, they are not sufficient to be the primary source of tracking. They are the periodic "i know i'm here" updates between the much more frequent "i think i'm here" updates

"The system has been stated to sweep the room 100 times a second. In 10 milliseconds, a single Lighthouse unit will sweep a first beam horizontally across the room. In the next 10 milliseconds, it will sweep a second beam vertically across the room. Finally, it will rest for another 20 milliseconds. Thats a total of 50 sweeps per second."
You have to remember that each laser sweep only gives you X or Y, you need two sweeps to get a position.
I like the liberty that you have in this game. Stacking beer bottles on the pool tables or doing trick shots with objects surely looks like fun.
This is the first time I see this game, looks really good, maybe one of the better looking VR games.
I guess I added 2 more games to my list.

Oculus Rift can do room scale VR, but doesn't see the demand for it

...outstanding. Yeahhh I'm not putting up with this ignorance. Flipping the Rift.

Time will tell. There's demand, but it's only once the Vive is released we'll know how many people can really take advantage of it in a real world setting.
The book in that Fantastic Contraptions Oculus teaser shows a Vive headset and controllers. Nice.
Xbox one can done cloud computing too.
You also have to have to make sure your turbo button is on and you don't have a disk in the A:\ drive.

i think the "who's got 15x15" is the worst part...its obvious it doesn't require the max amount of space possible to enjoy..so quit acting like it does.. Its smarmy
This sounds like trying to diminish the competition's product rather than anything.
In reality, at least in terms of image and promotion they were obviously caught off guard.

Sounds early, but I love the concept. I hope they get more to do in it beyond "pick them up and literally throw them in to jail" though.
Never thought about how perfect pool would be in VR. It's too bad using two headsets for local play is going to be such a luxury for a long while as passing the headset back and forth probably won't be too practical. Online play could be real cool though.
I think this is an awesome way to contextualize teleporting. I do agree it would be even cooler if they could combine this with some (even a little) room scale though. It looks like it would really benefit from motion controllers too. Not sure if it will be nearly as fun with a traditional controller and it obviously won't be as immersive.
Real pretty but too little to go on from the trailer.

I think the point is that the larger tracking space is where Vive's tracking system has the advantage since it's explicitly part of it's spec, and with two cameras Rift will seemingly be able to do a smaller room tracking space. What they don't see the huge demand for and aren't focusing their tech on is the maximum room tracking space.
That's not true though. The room tracking is room tracking be it minimal space or more. Room tracking is not advised/supported on Rift no matter the size. At least this is the current position.
And you said this, because?

I don't think "not advised/supported" is really the actual position. It's not the default set up, but they've made it clear that it can be done and developers are free to develop for it if they wish. They're just not pushing it, which is different to not advising it or supporting it.

So is anyone receiving updates on order status from Oculus yet?
Zalusithix

Ah, I wasn't aware of the actual sweep timing. I knew the general concept / math behind operation, but as far as timing went I only remembered the general "100 times a second". This could be interpreted as 100 complete scans or 100 partial. Not that it really matters. It only needs to be fast enough to keep the IMUs in check while subject to human movement speeds. In that job, the accuracy of the measurement and occlusion resistance are more important than pure update speed (beyond a certain point at least).

Here's a handy little guide to symbolic links on Windows: Lifehacker
I've heard nothing yet and I should (hopefully) be in the first wave based on order number.

Are there going to be OT's for these products? I don't think I've seen anyone volunteer in the OT OT.
Guess that means you could put a mirror at a specific location to create a path for sync pulses between stations that wouldn't otherwise have LOS. Could help with some of the more difficult setups.
Edit: not convex, that would create too many unwanted reflections.
The discussion was I think in this very thread, but Oculus is advising developers to track their games in 180 degrees. I'll search for the links.

Recommended or not, if you read the article Oculus does say it's possible, and pretty clearly.
So if a dev wants to create a room scale game it's not Oculus or the tech that's stopping them. And I would bet Oculus will change their stance anyway when Touch releases.
I wouldn't be surprised if the Touch controllers come with Room Scale VR cameras and that is why they kept delaying Touch. Just speculation but it seems viable.
I didn't speculate on what a developer can do against Oculus' recommendation, I only stated that this is Oculus' current official position on this topic. We can discuss what the future will bring and if and buts, but that doesn't change the current status.

Could you switch to a DP->HDMI cable for your monitor instead? Or DVI->HDMI?

Why do first person "Cockpit" games make us "less" sick than just walking in first person? Do our brains see a cockpit and think "Car, everything is ok", or something?
I assume the nausea you get in VR is similar to Car Sickness?
Third person movement has less chance to make you sick as well right?
So why not make a game where you "move" in third person and can zoom in to first person when you are stopped? You could even use the same "move to cover" mechanic as The Division.
Are Third Person Shooters and RPGs going to be the first somewhat traditional AAA experiences we get in VR?

So would I. But it would be nice to not have to guess and bet, and instead have something more concrete from oculus themselves

What the heck would a "room scale camera" be? A camera with higher resolution and FoV than the one they give you? If they're packing two of those hypothetical cameras with the controllers, Rift owners better brace themselves for the cost of going room scale.
of course its possible, but if it isn't the default setup then it's useless.

This is why I'm leaning towards Vive. It's not a deal breaker that Oculus doesn't have it but when you're spending upwards of $600 USD, whats another 200 to ensure that you do have the capability?
Edit: Oh and you get touch controllers included with the 200 USD premium.

It's not useless if it means developers of room scale games for Vive can also provide support for it on Rift knowing Rift owners who want that experience can reconfigure their setup to play them.
Their audience is fairly niche as it is, it would make sense for them to expand that to a subset of Rift owners of it's not overly difficult to support.
I'm going Oculus myself, but I'm really interested to see how Vive does room-scale. I have no interest in room scale itself, but new technology fascinates me and if they blow my expectations out of the water, I'm in. For now though, I'm keeping my expectations very conservative and want a darn good sitting VR experience for my first purchase...... and since I got in to the first Oculus preorders, that's the one I'll get.
