Spatial computing doesn’t arrive all at once—it kind of creeps in, almost unnoticed at first. A phone overlays directions onto a street, a headset places a floating window in your living room, a sensor maps a space so digital objects don’t just appear but stay anchored where you expect them. Then at some point you realize the interface is no longer confined to a screen. It’s around you, layered onto the environment, reacting to where you are and how you move.
