What should I ask about XREAL screen anchoring?
Ask what the image does when you turn your head and when you move your head through space. Also identify which behavior comes from the glasses and which requires an accessory or software configuration.
Rotation and position need different explanations
We would have the demonstrator show both movements. A screen that responds to turning has not necessarily demonstrated position tracking when you lean. The distinction is easy to miss if the entire demo happens seated and facing forward.
Choose a real object near the apparent screen position, turn away and return, then lean sideways. Describe what the screen does without assuming the same behavior applies to every XREAL model or accessory. Exact configurations make anchoring comparisons meaningful.
