MR Tech Community closing soon
It is with a heavy heart that we announce the closure of our Mixed Reality Tech Community. As Microsoft is no longer manufacturing and selling Microsoft HoloLens 2, and there are no further investments in new features or functionality, we will be shutting this forum down on March 1st, 2025. We want to express our deepest gratitude for your support, enthusiasm, and contributions over the years. Your passion and engagement have been the cornerstone of this community, and we are truly thankful for the vibrant discussions and knowledge sharing. While this chapter is coming to an end, our team remains available on Microsoft Q&A or via email at mshololens@microsoft.com. While the following communities are not managed by Microsoft, they contain valuable insights and expertise shared by fellow enthusiasts and experts: StackOverflow, Reddit, and HoloDevelopers Slack. Thank you once again for being a part of our journey. We look forward to seeing you in our other communities. Warm regards, The HoloLens Team

MRTK 3 Pinch Recognition On HoloLens 2
Hi everyone, this is my first time posting here. Please let me know if I messed up something in this post. I am optimizing a HoloLens 2 application developed with MRTK 3 in Unity, and I have been trying to improve the sensitivity of pinch recognition. In other words, what I wish to achieve is that the object manipulators in the application are only activated by pinching when the user’s thumb-forefinger distance becomes 0 (or at the least very close to 0). I set the pinch open threshold and the pinch closed threshold of the hands aggregator subsystem of MRTK 3 to 0.08 and 0.03, hoping that MRTK 3 will only recognize pinch in the more sensitive way mentioned above. However, the object manipulators are still activated by pinching even when the user’s thumb and forefinger are quite far away (about one half of the length of the user’s forefinger) from each other. Is this because of the hardware limitation of HoloLens 2? Is there any possibility that I can improve the pinch recognition on HoloLens 2? Big thanks in advance!

UWP 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. The capability setting in AppxManifest file is: <Capabilities> <Capability Name="internetClient" /> <Capability Name="internetClientServer" /> <Capability Name="privateNetworkClientServer"/> <uap:Capability Name="documentsLibrary" /> <uap2:Capability Name="spatialPerception" /> <DeviceCapability Name="webcam" /> <DeviceCapability Name="microphone" /> </Capabilities> The application tested all OK in unity editor but when loaded to hololens it failed to establish a network connection. Does anyone has any idea why the app has been blocked by hololens firewall? Thanks

HoloLens 1: Gestures not recognized in Unity 2019.4 with MRTK 2.8.3
I own an HoloLens 1 and so far I have developed some AR projects with Unity 2018.4.23f1 using the HoloToolkit (the version available in 2018). Now I want to develop a new project for HoloLens 1 with Unity 2019.440f1 LTS and use MRTK 2.8. I also use Visual Studio 2017. I created a new project and followed Microsoft's instructions on how to install and configure MRTK 2.8.3 (for example, I followed Microsoft manual "Set up a mixed reality project in Unity with the Mixed Reality Toolkit"). I added the MixedRealityToolkit to the new scene I created. For the MRTK Profile configuration, I selected the DefaultHololens1ConfigurationProfile. In the Input section, I activated the InputSystem and selected the DefaultHoloLens1InputSystemProfile. To verify that everything was correctly configured, I added to the scene a 3D cube, and, following Microsoft suggestions, I added the ObjectManipulator and NearInteractionGrabbable components to the cube. When I connect the HoloLens 1 to Unity through Holographic, I correctly see in the Hololens 1 the cube in the scene. Also, if I move the pointer over the cube, it correctly detects the presence of the cube. However, no gestures are recognized and therefore I cannot have any type of interaction with the cube. Even adding a bounding box with handles doesn't change the situation. The handles are recognized (their icons change) by the pointer, but then gestures are not identified and the presence of my hands in the FOV is not detected. I tried creating a new project several times starting from scratch, changing profiles and configurations, but the result is always the same. Is there something I'm doing wrong or missing? thank you for your help

Web navigation using WebView 2 in Hololens 2 + Unity (MRTK2)
Hi! I am trying out WebView2 Preview on HoloLens 2 using Unity 2022 and MRTK 2.8. Everything works great but I am not able to click on web's buttons, do scroll, etc. I have found this section of the documentation -> https://learn.microsoft.com/en-gb/microsoft-edge/webview2/get-started/hololens2#input which seems to point to web navigation, but I am not able to get it working. Any ideas? Thanks!
