Hi there,

Is there smth wrong with spatial target on Android devices? I use Samsung S21 Ultra. When I put my model on floor or table, after a while it simply drifts away... Has smth changed in implementation?

 

I don't experience such issues on iOS.

What kind of surface are you using as a target? Does it have some visible "texture" to it, e.g. wood grain or tiles or something like that? Or is it a plain flat monochrome surface? In the latter case, the camera may have trouble keeping tracking as you move around. If that's the case, try finding a flat surface with more visible features and see if it performs better.

 

You might also be able to get better tracking by playing with the "Extended Tracking" and "Persist Map" options on the 3D Container widget. Try different combinations to see if there's a configuration that solves the problem for you.

Hi @ClayHelberg,

thanks for pulling up my post. As far as I know, Spatial Target should pick device AR implementation for surface recognition (for Android ARCore, for iOS ARKit). I used wooden floor which has many non-pattern details for better plane recognition. You can see three videos down:

1. how spatial tracking works on wooden floor

2. how spatial target works outdoor with additional toys I put to make environment more heterogeneous

3. How a AR Elements app (App to demonstrate AR Core essentials) works on this phone (Samsung S21 Ultra)

Yes, I can see that the stability is not very good there. Have you experimented with the "Extended tracking" and "Persist map" options in Vuforia Studio? They may help you take better advantage of the AR features offered in your phone's OS. These are options on your "3D Container" widget in Studio:
