Hi!
So I'm working on Hololens 2 (with MRTK for most of the XR part), and I need to spatially anchor my objects so they keep accurate positions. I also need to make the spatial anchor persitent and/or store them on a server to keep them between sessions

I was wondering what was the right way or at least package to do that theses days. I've looked at/tried:
- Azure spatial anchoring: it'll stop soon and i need to keep my project fully opensource and free to use
- AR Anchor from AR foundation: I managed to make the anchor work, but I can't make the saving and loading the the XRAnchorStore part works (I can provide more details if needed). And between deprecated methods and documentation that aren't up to date I can't find any guide that works. ChatGPT helped me a bit but reached its limit too.
- World Locking Tools: It creates error when I import it and also seems uncompatible with MRTK 3

Does anyone know either how to make one of theses solution work or can recommend be a better one or an up to date guide?
If not, could using QR codes be a good option?

Thanks a lot

Cannot find a change-log for this update that appeared on my HL1. It’s 2024–0B Update for Windows 10 version 1809 for x86 Based Holographic Devices. This is more of a heads up post, for when you guys install and hopefully find something on it.

Hey hey everyone, is there a subreddit to sell my HoloLens 2? I have it in original box and case.

The device as far as I know is bricked due to a faulty update released by Microsoft. For some reason the device is not charging above 1 LED light (Even when charging it overnight).

Microsoft customer care suggested to re flash the device which is a simple straight forward process but the device is nowhere the minimum 40% charge because of some restriction.

Getting into EDL mode by pressing the Brightness UP + Brightness DOWN + Power button until the LED's disappear only enables me to update the driver using the device manager window.

Thinking this as a bypass to the 40% charge requirement, tried connecting to the ARC software with the latest .ffu file and the recovery .ffu file (in case the process got stuck).

ARC opens a page which says unable to connect to the server (which I understand) but will not let me choose the manual package file I have downloaded. The option is greyed out. Tried everything but no luck.

Tried to solve this using the Windows Recovery tool which was used to recover LUMIA phones back in the day, the device does not want to connect to anything.

If anyone has any ideas on solving this, I am all ears!

I just checked on my Hololens, there's no support for WebXR anymore, and on Microsoft's documentation aka.ms/WebXR it says that WebXR exists, but is not officially supported.

Does this mean that Hololens 2 will just not support WebXR anymore?

I found a very interesting offer on eBay Trimble xr10 But without a helmet, and I have a question, is it possible to buy only a helmet? (Edit: eBay lot https://apisd.ebay.com/itm/null/156389135249?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=zZOUen5yRva&sssrc=4429486&ssuid=vzj8ymttrzw&var=&widget_ver=artemis&media=COPY)

Hi, I'm trying to implement WorldLockingTool for a cross platform project, which includes Android. The Microsoft Github Readme says that if it's possible to modify the plugin to make it work for smartphones. Does anyone know where I have to go to get started?

So I finding the right glasses to start experimenting with unity or unreal engine 4 but I found Only from japan eBay seller and sold 8 pieces and is a good offer?

I had just purchased a hololens 2.
I want to view my Maya models in hololens. There is no way or tutorial that I can find of.

Ridiculously complicated. There were few handbook pdf on Microsoft's site which cannot be downloaded. I am wasting my time downloading unreal, unity and unable to do shit.

9 years ago Microsoft in one of the first hololens demo demonstrated Maya viewing model in hololens.

In the view 3d model option of viewing obj. I can't open simple models of more than 10k faces. I can't view smooth (sub-d models)

What good is hololens if i cant view 3d files????
And no i dont want to only view inbuilt flappy bird flying around. I need it for my use case!!!!!!!!!!!!!!!!

~"no hololens team is fine, everything is going to plan" dude stfu you look like a scammer and now we know there isnt going to be a hololens 3 you ######, go to ####. All the people here defending him are #### IMO and are accontable.

My HoloLens has been lying around for a while and I decided to turn it on again, I’m trying to charge it but it has been stuck at 1 blinking indicator light for a while now, it is not booting, what should I do?

Friend gave me a HL 2 with his company logo. I work for a different company. Can I still use the device? Where do I go to create a Microsoft account that is eligible for HL 2? Many thanks in advance!!

Anyone have a repository of HoloLens apps? I’m struggling to find them mainly looking for RoboRaid and Young Conker. They do show up in the store but they all error out when you try. Other apps for the HL1 download fine, but any sort of “fun apps” error out. Tried Grafitti, young conker and Robo Raid. A couple errors that came up were “you have too many devices on your account” and or “you’re not in the right region”. I checked my device count and I have 5 (you can have 10) and my region is USA 🇺🇸 ironically, Washington state where the HoloLens was designed lol. Any help or guidance is appreciated.

For my thesis project im working with the hololens 2 to create an app that can be used in warehouses. The app will read a QR code and navigate the user to the specific box that correlates with the QR code. Anyone have any tips or guides/vids I should look into?

Hello, I am creating a 3D Model on Blender for Hololens, it should have some translucent textures like glass and semitransparent plastic, how can I create this? Nothing works, the texture looks good on Blender and other apps, but when moving to Hololens it looks either completely transparent (is invisible), or completely opaque and white. I am using the Principled BSDF shader and playing with alpha and weight (transmission).

So been playing around with my HL1. How does it make sense that edge doesn’t work at all on the latest os version, and Microsoft says to roll back to use the legacy edge? Can’t I somehow sideload the the older edge to make it work on the current build? Make it make sense. Why would Microsoft make the hl1 unusable with the latest update? I would love to roll back but I’d lose out on features, and the store working. Any advice? Kinda bummed.

Hello everyone, I am making an MR application that will be deployed/operated on a Microsoft HoloLens 2, it will involve object detection using a fine-tuned YOLO v8. Since I cannot use my Mac to develop the app, can I use cross-platforms like Flutter or React native?

I’m running into the following with my HoloLens 2. After leaving it plugged into my laptop overnight, it will no longer charge or boot.

When unplugged, pressing the power button results in a single light turning on, flashing 4 times, and turning off.

When plugged into the OEM charger with the OEM cable, the device has one light power on and fade in and out for a few minutes. After that, it stays lit but no further lights turn on, as would be expected during normal charging. After the one light remains lit, putting on the headset shows the Microsoft logo, but it never moves past the logo, even after 30 minutes.

When trying to reflash the device, it needs to be put in the recovery mode for reflashing, which requires 40% power. Since the device doesn’t seem to be accepting a charge, I don’t have a way to put it into recovery mode, which seems to be done while unplugged.

Did I somehow put the device into a weird mode? Any tips or suggestions would be appreciated!

THE FIX: Get the device into recovery mode by powering on while connected to a PC while holding both brightness keys. You’ll know when you’ve done this correctly when you see an unrecognized device in Windows device manager similar to the following: “QUSB_BULK_CID:0402_SN:XXXXXXXX”.

Go to Windows Update and make sure optional updates are turned on. You can do that by going to Windows Update > Advanced Options > Toggle On “Receive updates for other Microsoft products”

Force Windows update to fetch the Qualcomm Ports driver. You can do this by pausing and resuming Windows update. You’ll find the Qualcomm driver under Windows Update > Advanced Options > Optional updates > Driver updates. It’ll be named something like “Qualcomm Incorporated - Ports - 3/25/2016 12:00:00 AM - 2.1.2.2”. Install it. Once you do, the unknown device in Windows Device Manager will be replaced by a device similar to “Qualcomm HS-USB QDLoader 9008 (COM3)”.

Open Windows Advanced Recovery companion. Download it and install it if you don’t have it. Once you have it, launch it. It won’t automatically find the HoloLens, so you have to select the manual option. Once you have, it should detect the HoloLens and allow you to install the windows OS to it.

Hi All

So, today I tried to update my via ARC. Started the process and it got to about 10% and lost connection, no idea why device has left alone connect to the PC, nothing I can tell interfered with it.

The screens then went completely red and the device shutdown. At the point all 4 white LEDS came on, but that was it, not recognised by PC and wouldn't turn off without full reset (Hold Power + VolDown button).

The only reaction I get from it is via holding Brightness up + brightness down and power, then all the LEDS switch off, but the device presents as a Qaulcomm HS-USB QDLoader 9008. Arc doesn't autodetect it, however does seem to see it is I manually select the device.

When I try to reflash it immediately starts recovery, gets to 1% then fails.

Any ideas greatly appreciated as this is driving me a little mad.

Thanks in advance for any help.

Hi there, I’m thinking of purchasing a HL2 for a person project to do some developing of software. The price for the one I was looking at is £450. Is this worth it or should I look to the Quest 3 for AR development?

We have a severe lack of 3D AR smart eyewear. There's HoloLens 2 which has worked well for my purposes, even in a ruggedized environment, but Microsoft is all but forgotten it. Just waiting for them to pull the plug. While Magic Leap didn't really work for my environment (safety glasses needed, wired solution), at least it was an alternative. Now they are moving to licensing their technology, which implies they are getting out of the hardware business. I've not tried DigiLens ARGO, but there doesn't seem to be many COTS software packages that support it (I'm only aware of Taqtile Manifest). Yes, VR headsets with passthrough video are all the rage, but I can't see using that in a ruggedized environment and could be a safety hazard if it fails.

Thoughts?

Hey there, I am trying to use the HoloLens to do something unusual. I want to use the Lidar information to feed information into an offsetting device that detects objects and gives me their position based on the HoloLens position + heading + distance to the object.

For this last part to work I need access to the Lidar using the Research mode, would anyone be able to point me to a tutorial that shows how this can be done? It would be cool to feed into that data stream similarly to what is done with the video camera.

As the title says, is it worth it in 2024? I work from home and I’ve seen the holo 1 go for about $150-200 now used, and want something I can stream my Xbox, and pc to, watch videos, and work from it. Am I silly to even consider it? Any advice is appreciated

I work for a HVAC drafting company and we are looking to implement AR for clash detection, Digital Engineering and future facilities management. We have been looking at the Hololens for ages but the price point in Australia is so high ($5000) to take a punt and test it. Is a second hand gen 1 worth a try to test how models would look and work before going all in?

We still operate on Windows 10 if that changes anything.
