Guidance on stable, smooth gyroscope sky navigation?

[joinother]

Hi! I have been working on an experimental HarmonyOS port and am trying to make the gyroscope-based sky view feel stable and natural.

I may simply have missed the relevant part of the codebase, so I wanted to ask whether Stellarium has an existing reference implementation or recommended approach for this. In particular, I am trying to understand:

• how device orientation is converted into the sky-view direction;
• how the view is kept from unexpectedly rotating or drifting around the centre; and
• what smoothing or filtering approach works well without making the motion feel laggy.

The open-source code I found seems to cover related orientation concepts, but I have not yet found a clear mobile gyroscope control path. Any pointers to source files, documentation, or design notes would be greatly appreciated. Thank you!

This simply isn't implemented. The only port that would benefit from it so far has been Android, and it's still incomplete.

The desktop version developed in this git is not geared towards mobile use. I too rarely feel the need to hold up and align my 34" screen with the sky (and it has no gyroscope). Mobile ports come by external contributions, but most are incomplete.
