I noticed Lenovo's recent announcement of the new T1 Glasses.
On further examination I discovered that T1 supports Screen Anchor Mode that allows to anchor 2D display into position independent of head rotation.
This feature appears to be independent of SDK or any apps/settings/software running on the host PC/Phone. This means that you could anchor a BIOS screen of your laptop/PC.
Processing of 2D screen shifting/zooming is done entirely by the glasses.
Unity/Unreal or OpenXR are not involved.
Is it possible to find out how this is achieved independent of SDK?
Are there plans to make this feature available to other XR1/XR2 glasses or headsets?
