In image target- Advanced, I can't choose Extended Tracking. It shows that "For extended tracking capabilities please use the DeviceTracker"
But I have select "Track Device Pose" in Device Tracker. And It shows that "Developers looking for extended tracking functionality should enable the Positional Device Tracker".
But I can't fand where to select Positional Tracker?
Hi,
There are 3 things to consider.
1. You need to select in the Vuforia config
2. The Extended tracking is activated per Target basis and it is by default ON. This option is available under each Target under the Default Trackable Event handler: Tracked or Extended Tracking
Here more info regarding Device Tracker with Unity: https://library.vuforia.com/content/vuforia-library/en/articles/Solution/Configuring-Rotational-Tracking-in-Unity.html
3. The device being used, Android or iOS. For Android you need to make sure that under the vuforia Configuration -> Android Settings -> ARCore requirement: the option Optional or Required is selected.
For IOS steps 1 and 2 are enough and you will have Extended tracking.
Also you need to check if your Android device is compatible with ARCore. Under this link you will find more info: https://library.vuforia.com/content/vuforia-library/en/articles/Solution/arcore-with-vuforia.html
Thank you.
