Please share your experience with tethered cellular
We've recently added a new docs page to include more information on connecting HoloLens to cellular networks. You can find it athttps://aka.ms/HL5G. While hotspot / WiFi is sufficient for most use cases, there are still times when tethering provides some benefit (for example ultra low latency or Azure Remote Rendering). Though we're unable to provide a curated list of cellular devices that are compatible with HoloLens 2, we're hoping folks in our community can share your own experience with the devices that have worked for you. Thanks in advance for sharing, and thank you for being part of the community!13KViews6likes39CommentsMesh App not working
Hi guys, I'm facing an issue of not being able to connect to the server when loading up the Microsoft Mesh app. The message shows "Failed to connect to server". Things I've tried: - Changed the internet connection to a different wifi and phone hotspot - Reinstalled the Mesh app - Windows Update for the Hololens 2 - Factory Reset, logged in with a new user and attempted to start the app None of it worked, and the same error message persisted. Is anyone facing the same issue? Could it be that Microsoft stopped managing the server for the app? Any help is much appreciated. Thank you! Regards, HanSolved8.5KViews2likes18CommentsReal world object detection
Hi All, I hope this is the right place to ask this question. If it is not, please point me to the right location. Thanks. I have been asked to develop a HoloLens 2 healthcare application that should work as guide for patients on how to handle different devices for blood sugar measurements, insulin pumps etc. But I need some help/information for how to do this the best way. The HoloLens 2 application must be able to recognize the device (blood sugar measurement device) on the table, so that it can start telling what to do with it. Are you able to help me with this? Thank you in advance927Views3likes13CommentsWhat are the negative effects of virtual reality?
While virtual reality (VR) has many potential benefits, such as enhancing education, entertainment, and even therapy, there are also several negative effects associated with its use. One of the most common negative effects of virtual reality is motion sickness, which can occur when the brain perceives conflicting signals from the body and the VR environment. This can cause nausea, dizziness, and disorientation. Another potential negative effect of virtual reality is addiction. Some users may become so immersed in the virtual world that they lose touch with reality and become dependent on the experience. This can lead to social isolation, neglect of responsibilities, and even physical harm. Virtual reality can also have negative effects on physical health. Extended use of VR headsets can cause eye strain, headaches, and neck pain. In addition, some VR games and experiences may require physical movement or exertion, which can lead to injuries or muscle soreness. Finally, there are concerns about the psychological effects of virtual reality, particularly on young children and adolescents. Some experts worry that prolonged exposure to virtual environments could lead to behavioral changes, desensitization to violence, and even increased aggression. Overall, while virtual reality has many potential benefits, there are also several negative effects to consider, particularly in terms of physical and psychological health. It is important for users to be aware of these risks and to use virtual reality in moderation.8.9KViews0likes13CommentsHololens 2 experience is a dream to use.
Would it be possible to engineer a new setup where you can use a more powerful computer that is either backpacked or long-wired to a super-computer in the building? Just have all the sensors and display be routed to the main more powerful PC. Being limited to 4GB as well as Snapdragon 850 can only take you so far. It's great for now but the potential of this is just so high but crippled by trying to compact it into something all headmounted only. The escape from actual reality is clearly awesome with incredible potential. It can actually make reality better too. Unfortunately, a lot of top engineers are doing BTC and other easy ways to make money or just straight retiring. Imo, all this makes life better that people would love to develop and use if only it could be easier and the toolsets seamless to make. Some apps are so great that you might as well use them rather than try to make things yourself in Unity as the time it takes to make a basic scene then upload/run it is super long. Moving objects to the cloud and having it near instantly show up on the display to drag n' drop is great. The world that I've seen in Hololens 2, I can't live w/o. I hate coming back to the 2D reality we have now. 😞 I have the screens setup so when I go all the way right I have the experience. I use the keyboard from the main PC through Developer Deploy to type. It's not that I'm doing everything in the Hololens 2 but having the Hololens 2 along with using the main PC makes the computing experience a lot better.1.5KViews0likes7CommentsQuestion regarding outdoor-use scenario for forestry-training
Without access to a HL-device I am looking for an assessment/opinions regarding the following usage-szenario: For a remote training of farmers in a tropical environment we are looking into using HL2 + Dynamics 365 Remote Assist, where the expert (in a remote location) gives guidance to the course participants wearing the HL and working outdoors on the trees (pruning of trees etc.). I know that HL2 is designed with indoor use in mind. Still I'm interested in owners or maybe MS employees on the feasability of the described scenario and the possibility to overcome some of the challenges (providing shade for better visibility and cooler environment, setting up markers for better spatial recognition etc.) Thank you!1.5KViews0likes7CommentsWhy my few applications not work with my Microsoft email?

Hello, I am using the following tools: TelloforUnity MRTK v1.0.2104.3 Beta Unity 2019.4.28f1 I want to be able to see the drone's camera feed on hololens. Using only TelloforUnity I am able to see the camera feed on Unity when I start the Scene, but when I try to launch the project to Hololens all I am able to see is a white screen in the area where the video should have played. For anyone who is familiar with TelloforUnity, I created a new project, added the MRTK and I added the TelloVideo to my scene. The video works fine in Unity but not on Hololens. Any Ideas how to fix this issue or how to stream a video to Hololens?Solved3.4KViews0likes6CommentsImage Processing or Video processing with OpenCV + Unity
Hello I am a student from Belgium and I 'm doing my thesis with a hololens2. I have to make an application on the hololens for bad sighted people. To do that, I have used the free OpenCV package with Unity. I need some help with the MRTK packages and how to use MRTK and OpenCV at the same time. Is there an example program that already uses OpenCV with Unity for the Hololens2? Many Thanx Bart Punie8.5KViews0likes6CommentsUWP app network connection blocked by hololens 2 windows firewall
Hello, my UWP app, which was installed on the HoloLens, has encountered an issue and is now unable to connect to the internet.I checked the hololens diagnostic log and it stated the following event: "Windows Defender Firewall was unable to notify the user that it blocked an application from accepting incoming connections on the network. Reason: The application is non interactive Application Path:.....". My development setup includes Unity 2018.4.11f1 and Visual Studio 2019.

Hi, my company has been using HoloLens 2 since September 2020. So it's been almost a year until today. During this time period, the HoloLens 2 had been used mainly as tools for presenting demo to clients about the following applications: 1. Dynamics 365 Remote Assist, 2. Dynamics 365 Guides, and 3. Trimble Connect. The issue that I would highlight in this topic is the overheat problem in HoloLens 2. At first, the usage time (full usage of remote assist) could range between 60-80 minutes (outdoor) before the appearance of the overheat warning. But as time goes by, the time usage dropped drastically and therefore the frequency of overheating increases a lot, even when used indoor at room temperature. In the most recent case, the average usage time until the overheat warning appeared is between 30-40 minutes (it varied based on the running application). If there are any similar issue, please kindly share your experience with me. If someone knows the roundabout solutions for this issue, I appreciate it a lot if you could drop it in this thread.3.6KViews0likes5CommentsError When trying to open 'Advanced Properties' section of Tap to Place script
