A boundary defines the area in which you can move around while you're wearing your Windows Mixed Reality immersive headset. Because you can't see your surroundings while you're using your headset, it's important to create a boundary to help you avoid obstacles. The boundary looks like a white outline inside mixed reality, and appears when you come close to it. When you see it, slow your movements, and avoid crossing the boundary or extending your limbs beyond it.
The area inside the boundary should be free of furniture and other obstacles, including the area above you (think about low-hanging light fixtures or ceiling fans). This way, you'll know that as long as you stay inside the boundary, you won't bump into or trip over anything.
When you first set up your headset, you'll have a chance to create a boundary. The setup app (Mixed Reality Portal) will take you through the steps. If you have trouble creating the boundary, see Set up Windows Mixed Reality FAQ.
If you choose not to create a boundary during setup, you can create one at any time by selecting Start > Mixed Reality Portal on your desktop. Open Menu , then select Run setup to create a new boundary.
If someone new uses your headset, make sure they understand the boundary and how to use it. And if you move your headset to a new location, you'll need to set up a new boundary that works for that space.
If you choose "Seated and standing," either during headset setup or later on, you'll be using your headset without a boundary. This means you'll need to stay in one spot when using the headset, so that you can avoid physical obstacles and tripping hazards. You can sit down or stand up, but you won't be able to move around. Keep in mind that obstacles might be overhead as well as around you.
Some apps might be designed to work with a boundary, so you might not be able to use them, or might not have the same experience, if you use them without a boundary.
If you choose "All experiences," you'll set up a boundary, and will be able to use apps and experiences that work with a boundary as well as those that don't require one.
Windows Mixed Reality might sometimes have trouble identifying a boundary that you previously created. If this happens, you can choose to create a new boundary, or you can choose to use your device in Seated and standing mode.
