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 used to love hololens2 and still do. I used to provide "pro bono" support for everything HoloLens, answered questions on their forums, reported spammers, helping the community the best I could.

HoloLens 2 was amazing piece of hardware. The software was and is still amazing.

But MS got greedy, they fired all their mixed reality devs, jacked up all the pricing on everything, and discontinued momentum and practically all support for Windows Holographic and mixed reality apps.

So now we are divesting the best we can. Friendship ended with MS.

I wish MS would budge, but the greed is just too much.

In the future I will do everything possible to not buy from them again.

Sorry I can't elaborate much on why, but I'm just done. Too much greed. I wish it didn't have to end this way. This post will probably get deleted soon, but I just wanted to say, So long, thanks for all the fish.

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.

Hello Everyone,

I am working on a project that requires me to find the homogeneous transformation between the RGB camera on the hololens2 to the display visor. Does this exist, and where am I able to find it? Thank you!

Hi there, currently thinking of switching to a MacBook, does anyone know if I can still develop applications for the HoloLens using a MacBook? I know that I can emulate Windows on ARM with a MacBook that has an M3 but you never know.

Does anyone have feedback on that? Is it possible? Is it a pain in the ass?

someone has already succeeded in importing an animated model into Hololens 2. Could I please ask how it could be done. I use Blender 3d.

Hello,

I am having trouble with voice inputs for the MRTK Framework in Unity. I have the MRTK speech component enabled in the XR Rig, and when I hover over my action buttons, there is a “say ‘select’” pop up. If you click the button it takes you to a new scene. However, when I say select nothing is being done. Additionally, I have made a script using the KeywordRecognition Subsystem to listen to for Keywords. Yet when I say the key word nothing occurs. Does anyone have any possible ideas for why it’s not working?

Hi folks. Asking a question for a colleague working on Hololens 2. According to the Microsoft documentation, when you set up Device portal to work between a PC and a Hololens 2, you have to set up a user account specifically for it.

Does anyone know if activating this account wipes other existing user accounts or user data? My colleague was seeing language in the device portal interface that made them think so, and has other user data they don't want to wipe.

Thanks in advance!

I'm working on an application where the user works with physical tools that the app needs to track in AR. Solutions that use full object recogintion (e.g. Vuforia) seem needlessly expensive both in money and compute, so I thought I'd try the tried and true solution of using retroreflective markers attached to the tools.

This seems like it should be a common enough use case for it to be supported in MRTK or AR Foundation, but I haven't managed to find anything useful in the docs. My googling yields mostly medical papers with no focus on code or solutions using Research Mode which is not an option for me as I want to be able to publish the app.

Does anyone know what the best path forward here would be?

Dear community, I need your help.

I deployed a 3d model in unity to my hololens 2 and now want to interact with parts of the 3d model f.e when i click a pipe it shows a text „this is the pipe X and it does …“ How do I make parts of the 3d model interactable - what do I need to optimize in Unity?(I am a beginner)

Hi I was able to download the mirage app for both my desktop and Hololens. I was able to get the Hololens to connect to the server via the QR code, but cannot get the streaming to work once in. I am able to add a monitor to my displays, but when I click stream via the three dots in the top right corner I see a quick flash of what should be a virtual desktop via the Hololens, but it quickly disappears. Has anybody experienced this issue? Or knows of a solution?

I am currently working on a project for the Hololens 2 and wanted to incorporate Eye Gaze for Holographic Remoting. I feel like I'm so close to fixing it and I'm just missing one checkbox or something. In the past, I have successfully implemented Eye Gaze in projects using Holographic Remoting, so I don't know why it suddenly doesn't work. I have followed the instructions here:

https://learn.microsoft.com/en-us/windows/mixed-reality/mrtk-unity/mrtk2/features/input/eye-tracking/eye-tracking-basic-setup?view=mrtkunity-2022-05

I also went through blogs by Joost van Schaik and countless posts on forums, but nothing seems to be fixing my issue. In Unity, there is an Eye Gaze Cursor GameObject, however, it follows the position of my head, not my eyes, and it only renders at the start and hides as soon as hands are detected. CoreServices.InputSystem?.EyeGazeProvider?.IsEyeCalibrationValid is returning true, so it isn't an issue with eye calibration. I just don't understand why this seemingly simple implementation has taken me all day. If anyone has any tips, they would be greatly appreciated.

EDIT: To give some more context, the Eye Gaze cursor GameObject does appear when the scene first loads, however disappears when the hands are first detected and will not reappear. It also only follows the head and not the Eye Gaze. This post linked below is along the same lines as what I'm experiencing (although it doesn't look like they want eye gaze in the first place) but is above my level of understanding: https://github.com/microsoft/MixedRealityToolkit-Unity/issues/6320

Calling all XR devs, holoLens 2 app devs, and general experts in this process that includes VisualStudiocode. Who here still develops with the aforementioned programs, which version of Unity and which version of Visual Studio code do you use as of July 2024 to create usable and testable apps still? I'm a ux and ui dev trying to work on XR design and finding only out of date videos with our of date info that doesn't work too set up and test a project. We need new videos or instruction reviews. So asking current devs, how do you start 🤔?

Hey Holo community,

I just recently got the Holo 2 and wanted to illustrate a 3D model I have in unity in the Holo 2. I tried several different tutorials on youtube & articles but could not get the Holo to show my 3D Model from unity Does anyone have advice or can refer to a source which helps me solve my problem?

Trying to get the remote assist to work, and figured a device license would work because I have a lot of potential users. but at 50 dollars a user seems not great for a ton of users but the device licenses seemed to be what we needed, however it seems that it's not a device licenses as much as a "single account" that everyone can use but assigning the shared account a device license having everyone log into the same account? this is not ideal in a secure environment. Also seems like why even use the 250 dollars device license with a single account when you can just use the one user account license.

The HoloLens 2 is by no means new technology, yet there's still nothing else quite like it on the market. With Microsoft constantly announcing layoffs in the HoloLens space, it seems it's only a matter of time before they sunset the device as well. There also doesn't appear to be any work happening on a HoloLens 3 either.

What do you think the next device will be? Something that is fully AR and also 100% self contained with no external wires.

Hi all,

I've been trying to figure this out for a while, but it doesn't seem I have found a solution and maybe someone out there has a similar issue.

I would like to install the Holographic Remoting Player app on the hololens 2 offline via the standard provisional package process as a appxbundle.

It seems to install fine, but when I launch it, it refuses to launch. That being said, I tested it to enable it with Internet and it launched as expected.

Is there a way to "authenticate" the app so it doesn't need to ping the Microsoft Store to use? It seems after that first ping, I can take the device fully offline and use it as normal.

But of course, due to environment, everything must be offline and disabled for WiFi, etc.

Any direction or answer would be much appreciated!

The wifi direct virtual adapter in hololens2 settings sand Bluetooth virtual adapter shows as "non operational". I can not use wifi direct. Does anyone know how to uninstall/reinstall or fix these drivers?

Hello, is there a way to only use gaze and dwell for Hololens 2 instead of hands or voice? Not just within apps but to navigate the whole device in general. For e.g. I gaze and dwell on an app on the menu to open it up. If it's not in-built, does anyone know of a hack-y/programming way of doing this? Thanks!

After years for waiting on a used hololens to be affordable I finally ordered one. For an overview of what I want to achieve is a program that will let me look at objects recognize them with a 3d overlay. Some able to be picked up and some stationary and have them anchored to a location where i place them. I'd like to be able to label them and add a cable that snaps to a location on the 3d model (inputs and outputs on a device). I'd like to be able to label change color of the cable and have another end that i can attach to the second object. Hopefully id be able to scan and upload a new object through the hololens if not ill do prescans and have it as an asset in the project. It'll be a 3d wiring diagram basically where I can see what cables I have plugged into what input and output and show some else where to run cables. I'd like to upload and see a room schematic from a picture taken through the hololens that I can view as reference. And hopefully be able to map the locations of the objects in a room size of 100'x200' up to 300'x500'. I'd like the project to open like a sandbox scan a room and bring in all the elements that i can place. If anyone has any good tutorial videos I can watch that can help me add some of these aspects into a project that would be great.

I am reading through the MRTK documentation for mixed reality capture.

I can see how to video capture with holograms, video capture without holograms, but is there a way to capture just the holograms (no real world)?

At my workplace we have introduced the hololens 2 for remote help with the maintenance teams on rotations. But we want to extend the use of the device. And one idea was to use it for integration of the new employees.

The idea is to create an environnement with contextual nodes that will just float and wait the user. And when the user interact with them it will show the images, assets , videos or texts. In some kind of contextual screen. We want them to just be all there waiting for the user in the 3d space.

Is there a software or app like that on the market?

We have a setup where we run an AR simulator app on a laptop and on the headset same time and it works fine. But when we try to cast the image from the hololens to the laptop the miracast loose connection very often. 2 days ago it stopped casting completely. Basically it doesn't connect up via the Bluetooth. We have 2 headset a H1 and a H2. Both has got the same issue.

Basically the title, Is it possible to develop video playing/streaming app for HoloLens using electron js ? And please give me examples of some of the apps developed for holo lens using electron js for similar application if possible.

Recently, i bought a Hololens 1 headset for around $220, and it's actually quite good as my first AR headset. The small FOV initially bothered me, but i got used to it. Microsoft Edge Legacy mostly opens up the websites i need, even the official YouTube mobile website opens and loads videos. The system reminds me of Windows 10 Mobile, runs well, lagging is only noticeable in some third-party apps or when opening a massive website in Edge. The exclusive first-party games like Young Conker and Fragments are impressive, Hololens could have more potential and apps back in the days, if not the price. The Microsoft Store is half-broken, you have to manually search apps. Battery life is not very long, about 3 hours of active use on brightness 3-4. Windows still gets very minor system updates, up to this day. Third-party Bluetooth devices, except keyboards and mice don't work properly, as Windows lacks the drivers for them (this is the issue of desktop Windows too, on Linux these devices work properly), the micro-usb port does not support OTG adapters. Hololens 1 can't be interop-unlocked using online guides for W10M.
