Hi everyone, I am a final year Master's student at Nanyang Technological University (NTU), Singapore. For my dissertation, I am studying whether Mixed Reality (MR) is perceived to improve the efficiency and quality of project management processes and workflows across the PMBOK performance domains.

I am looking for professionals who currently work, or have previously worked, in a project management or project related role where MR is used in processes and workflows. By MR, I mean technology that blends the physical and digital worlds, such as the Microsoft HoloLens and similar headsets, where users interact with 3D holograms in a real environment.

Have tried cooling fans that dissipate, but not a great way to attach. Need something reliable.

After I tried updating windows on my Hololens 2 and the update never finished. After I clicked on reboot device turned off and nothing happened. I let it sit for a while but it never turned on. Reboot doesn't doo anything. hard reboot also doesn't do anything. I tried to get it into recovery mode but that doesn't work, no LED blinking no nothing. I found on here setup to get it into EDL mode which I managed to do but when I open the ARC app I can't do anything. The app sees the headset but sites unknown OS version and unavailable version with blanked out buttons. I'm stuck on this screen and can't get past it. If anyone knows please help

EDIT:a reboot unfucked it

Im trying to factory reset my halolens one, but once the device gets put into recovery mode, i get the same "usb device not recognized" and "failed to enumerate" error even with different PCs and Cables

recently bought a hololens gen 1 for cheap, but the owner didnt remember the password, can anyone help me reset it

cam we reset it normal way using wrt or not as i think it is no longer supported

Vendo hololens 2 praticamente nuovi usati solo x test. A qualcuno interessano?

Edit: It’s working! Tried it again and seemed to work fine. Not sure why it did not initially? I like to think maybe MS has some dedicated callbacks for HL1 device registration but those servers needed to be spun up LOL!

——

I recently got a HL1 that worked like a charm out of the box. It was signed into the previous owner's account, so I did a factory reset. However, I am not able to sign in to my own account!

I tried using an app password since I have MFA enabled but no luck! Is there any way to start using the device offline? Or to somehow login now?

I also flashed the latest version of the OS i could find as well, thinking that may help 10.0.17763.737 -> 10.0.17763.6660

Any HL1 owners have similar issues? or workarounds?

Hi all.

I'm just curious about the state of the HoloLens 1 in 2026?

I'd like to know how it does loading websites, like are you able to load websites like YouTube, Gmail, MS office applications Web version, etc. Can it still load?

What's the state of apps supported with the HoloLens 1? Is it as simple as finding the app, then sideloading it to the hololens?

Can you sideload any application as long as it's UWP and X86?

Can you sideload a new browser given that it is a UWP?

Thanks community

Hi,

Was wondering if anyone holds some HL2, he doesn’t need?

Thanks

Looking for the wisdom of the crowd... it seems like the Hololens 2 was well received in the industrial sector and companies were very disappointed that it was discontinued. Many companies deployed hundreds of units internally. I found online estimations that in total MSFT sold about 350k units, half of which were sold to the industrial sector.

So why did MSFT discontinue the product? If you comment, please start with a statement whether your comment is an opinion or is it based on actual information you know about MSFT's considerations.

Thank you!

I just booted up my HL2 and the brightness button doesn't react anymore (was working 2 weeks back). Has anyone experienced this and found a software way around for this? because the settings don't show anything for "brightness"..

Where can I download Holons projects created by fans? Most apps on the Hololens 2 don’t really work properly. There aren’t any great apps on the Store.

I have used hololens 1 and 2. I have the hololens 2 for about a year and it is in like new shape. I want to sell them since I finish with my project but don’t know where to. If any one interest, should me an offer!

Hi everyone,

I have been trying to pack some apps (ie. Firefox) with MSIX packaging tool for use on the HL1. However, I have had no luck so far. On the HL1, all I get is the spinner and the app goes to sleep, when I try to launch from device portal, I get error 0x80270254. TargetDeviceFamily in manifest is set to Windows.Universal (I have also tried Windows.Holographic with same results) and MinVersion set to 17763. I have also tried WSAppBak and yielded same results. Any suggestions as to what I should try?

Have a brand new HoloLens2 still in the box and not sure what to do with it. The wrapper has been taken off the box but that’s it. Purchased for potential work project but project died. Who wants it? Willing to give it up for cheap since I know it’s no longer supported.

Otherwise, what do I do with it.

I am a PhD candidate in 3D modelling and AR-technology in otologic surgery (ear surgery). I am a medical doctor doing a MD/PhD, and since I know how to code, I have done so myself. As of now I have been programming 3D-models and added them to HoloLens 2. With Microsoft discontinuining this product I am no longer able to purchase several other units, which I will need for my further research (after my PhD). What would be the best alternative? I want several surgeons/residents wearing the glasses together and looking at the same 3D-model, so I think an AR-type of glasses would be better than VR.

As of now I have been looking into Magic Leap 2, Almer arc 2 and Vuzix M4000. I think the latter two seems to be very industrial-leaning, and I think Magic Leap 2 will be the best choice, but would love the input!

Hi everyone,

this is a bit of a shot in the dark: I’ve been working on a small demo for HoloLens 1 to take part in a Demoscene event early april and I’m running into a persistent issue where the app always launches as a 2D window instead of a spatial holographic experience.

Setup:

• HoloLens 1
• Developer Mode enabled
• Paired with PC
• Reachable via WiFi
• Device Portal accessible
• Deployment via Visual Studio 2017 works
• Unity “Build and Run → USB Device” does nothing

Project details:

• Unity 2019.4 LTS
• UWP build
• Target Device: HoloLens
• Architecture: x86
• Build Type: D3D
• IL2CPP backend
• Min version: 10.0.14393.0
• App is extremely lightweight (~4110 vertices, 1 material)

The project builds and deploys fine via VS2017, but when launched on the HoloLens it opens as a flat 2D UWP window in the shell. No spatial projection, no stereoscopic rendering, no head tracking.

I have:

• Removed the Main Camera
• Tried keeping the Main Camera
• Adjusted Player Settings
• Ensured spatialPerception capability is enabled
• Verified manifest MinVersion

No change, it always launches as a 2D window.

At this point I’m wondering:

• Is Unity 2019.4 LTS simply not viable for HoloLens 1 holographic apps?
• Is there a specific XR/VR configuration still required for HL1 that I’m missing?

If anyone here has built a true holographic (spatial) app for HoloLens 1, I’d really appreciate insight into: Which Unity version was working last for it? Does the somewhat new XR Plug-in Management work at all for HL1 or if I need to downgrade Unity even further?

Please note that getting a HL2 is not an option, its specifically for this purpose, making something for a demoscene submission, and I try to keep it small enough to maybe qualify for sizecoding. Thanks in Advance!

Hello,

I have 2 Hololens 2 to sell. They have been used for approximatively 9 months during my PhD. They are now back to factory parameters. The charger are missing so I'll reduce the prices.

Do you know the best way to sell them ? I am condemned to use Ebay or similar websites ?

Thank you very much !

Hey folks — on HoloLens there’s Follow Me for app windows (Edge, etc.). I’m wondering if anyone’s built (or seen public/open-source code for) a different behavior that’s more like “stay in front, but offset”.

What I mean: a window that stays front-right or front-left while you’re walking, so you can keep moving forward and just glance to the side to see it. But it’s not rigidly head-locked — so if you quickly shake/turn your head, it doesn’t jitter/drag with your headset pose. Also not purely world-anchored where you can just walk past it and leave it behind.

Has anyone implemented something like this (app/repo/sample), or is there a known approach using MRTK / HoloLens APIs? Any pointers appreciated.

I have a HoloLens 2 with a broken head strap. After carefully opening the device, I found the issue: the plastic gear rail has snapped into several pieces.

I’m wondering if this part could be 3D printed, and whether anyone here has already attempted this repair. I haven’t been able to find original photos or CAD files of the gear rail online, but I’ve noticed I’m definitely not the only person running into this problem.

Does anyone know someone who could recreate this part as a 3D model, or have experience reverse-engineering small mechanical parts like this? Any advice, references, or previous attempts would be greatly appreciated.

Update

I was able to create a 3-D model and repair my device

I will give away the 3-D files for free, just shoot me a DM. If you attempt this, don’t try to remove the rubber that’s my only tip.

Hello everyone,

I’m an AR application developer currently working on a project where I need to combine gaze (eye‑tracking data) with the real environment, so that the system can capture the specific target in the real scene that the user is currently looking at (the gaze point).

I have a few questions and would really appreciate your insights:

1. Is there any existing API or method to access real‑time passthrough camera images on HoloLens 2?
2. Between HoloLens 2 and Galaxy XR, which device is more suitable for developing this type of application?
3. Considering that the HoloLens 2 developer community seems more active than Galaxy XR’s, how much should this factor influence my choice?

Context:

• My background is mainly with HoloLens 2 development.
• I’ve seen that some developers tried to access HL2’s passthrough camera images, but they were black‑and‑white and likely worse than QPro, so I decided not to continue development on HL2.
• Project deadline is approaching — I need to deliver a demo before April next year, so I must decide soon.

Any advice, experiences, or pointers to resources would be extremely valuable. Thank you in advance!
