What makes smart glasses spatial AR?
Spatial AR relates digital content to positions in the surrounding world. An object can appear beside a real table instead of following every movement of your head. That requires tracking and software support beyond simply showing an image.
Turning and moving are different problems
Rotation tracking measures which way you face. Position tracking also measures movement through space. The distinction matters when you lean toward a virtual object: its appearance should change appropriately if it occupies a location in the room. Ask what happens when you move, rather than accepting a stationary demonstration as proof of spatial placement.
Picture a label above a real door. A head-following label stays in the same part of your view as you turn away. A world-placed label remains associated with the door. Those behaviors can both be useful, but they support different applications and should be described separately.
