Interference of Vuforia Tracker while using AR Camera and Gyroscope

By kaarthickml on Thu, 10/31/2019 - 09:30

Hello

I am using Unity 2019.1 and Vuforia 8.3.8 to build an app for Android and iOS. It is a native app with a unity AR module that makes use of Vuforia ARCamera.

In one feature, I should be able to switch between AR mode and non - AR mode like pokemon go. I have a gyroscope script attached to the camera to display points of interest in 3D depending on coordinates from the backend

I switch between the AR and non-AR mode by enabling/ disabling the VuforiaBehavior. The gyroscope works perfectly in the non- AR mode and the POI gameobjects remain wherever they are placed. However, in the AR Mode, they start floating in a certain direction and do not stick to the co-ordinates they are supposed to. Also, the direction changes and keeps showing the wrong POI in the real world. Can this be because of Vuforia's device tracker? I am only using the ARCamera and not any image targets. How can I have the live camera feed alone but not have any tracking and let the gyroscope do the positioning of the POIs?

 

Hi,

Yes, Extended Tracking enabled via Device Tracker is doing exactly what you described. I would suggest to disable Extended Tracking and test your experience.
