I’m trying to create an application using Unity 2022.3.14.f1 and Visual Studio 2019 for the Hololens 2. The goal is to scan a QR code and render a virtual number on top of it. This number should increment over time. I’m not sure how to approach this problem. Any guidance on how to achieve this would be greatly appreciated. Specifically, I’m looking for advice on how to scan the QR code, render the virtual number, and update it over time. Thank you in advance for your help.

    Hello, Welcome to Microsoft Q&A,

    For HoloLens 2, our current recommendation is to use Unity 2021.3 LTS and Visual Studio 2022 for development. For more information, please refer to Choosing a Unity version and XR plugin - Mixed Reality | Microsoft Learn and Install the tools - Mixed Reality | Microsoft Learn.

    Regarding how to implement QR Code on HoloLens 2, you can refer to QR code tracking - Mixed Reality | Microsoft Learn and microsoft/MixedReality-QRCode-Sample at OpenXR (github.com). This sample also shows you how to generate some holograms at the location of the QR Code.

    Regarding the number that increases over time, I think you could try implementing a timer function in Unity's lifecycle function Update or FixedUpdate. For more details, it is recommended that you seek support from the Unity forum.
