Known issue: Vuforia 7.5.26 does work with .NET scripting backend on UWP in Unity

October 31, 2018 - 8:57am #1


A regression was introduced with Vuforia SDK 7.5.26 in Unity where using the .NET scripting backend will throw an exception when running a Universal Windows Platform build. This also includes HoloLens apps.

Please use the IL2CPP scripting backend instead, where this issue is not seen. We plan to fix this issue in an upcoming release.

Updated HoloLens resolution now available

March 21, 2017 - 9:39am #1


A patch is available for HoloLens performance modes for Vuforia SDK 6.1 and greater. This change updates the "MODE_DEFAULT" camera device/performance mode to use the 896x504 resolution, as recommended by Microsoft for Vuforia computer vision algorithms. Vuforia's testing shows an improvement in detection distances on HoloLens when using this mode. The previous MODE_DEFAULT resolution can still be used by selecting MODE_OPTIMIZE_SPEED (1280X720). MODE_OPTIMIZE_QUALITY (1344x756) remains unchanged.

Hololens voice-/movement commands

June 15, 2019 - 5:11am #1

Hey there,

my name is Tim Gehringer and I come from Germany. On my University, I have  a project where we  work with Vuforia. The task is to create a practical laboratory experiment with a smartphone and the Hololens. We want to use videos to show the students how it works.

The APP with the smartphone is finished but we got problems with the Hololens. We have no interface to start the videos or show pictures. We dont know anything about Java Script. Could you be so kind and sent me some code that I can use for some voice-commands for my HoloLens.

Holographic emulation uses pc webcam instead of hololens camera

April 23, 2019 - 6:56am #1

I am a beginner in working with unity / vuforia, and have followed a few example videos on how to setup and build a project on the hololens. But everytime I do so this happens.

When I try to emulate my project on the hololens, it will use the built in webcam of my pc instead of the camera on the hololens. The hololens shows whatever the webcam sees on it however, so i can see myself in it for some reason.

Is there a way to use the hololens camera  instead of the webcam?
