HoloLens blends holograms with your world, mapping your surroundings to remember where you place your apps and content.
For your HoloLens to work properly, HoloLens Wi-Fi needs to be turned on, though it doesn't have to be connected to a network.
Tips for setting up your space
HoloLens works best in certain kinds of environments. Choose a room with adequate light and plenty of space. Avoid dark spaces and rooms with a lot of dark, shiny, or translucent surfaces (for instance, mirrors or gauzy curtains).
HoloLens is optimized for indoor use. Use it in a safe place with no tripping hazards. More on safety.
Mapping your space
When HoloLens starts mapping your surroundings, you'll see a mesh graphic spreading over the space.
To help HoloLens learn a space, walk around the space and gaze around you. Air tap in a space to light up the mesh and see what's been mapped.
If your space changes significantly—for example, if a piece of furniture is moved—you might need to walk around the space and gaze around you so HoloLens can relearn it.
