Why is it required? Because users wearing head-mounted displays cannot see their surroundings. So, it is essential to create a boundary to help avoid obstacles and collisions.
The boundary mainly appears as a white outline inside mixed reality and becomes instantly visible the moment you step in its proximity. Its appearance signifies the end of the safe zone so, slow your movements and avoid extending your limbs beyond it as you might bump into living room furniture.
Create Boundaries in Windows Mixed Reality
It’s easy to create Boundaries in Windows Mixed Reality, but you should be mindful of certain points. For example, during setup, you can choose to create one Boundary at any time by selecting Start > Mixed Reality Portal on your desktop. Or you can open Menu, select Run setup to create a new boundary. 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 get an error message while creating a boundary, follow these guidelines. Finally, if you choose not to create a boundary or remove it completely, follow these steps. Select Start, choose Mixed Reality Portal and open its Menu. After that, simply turn Boundary to Off. While the boundary is off, make sure to stay in one place. Source.
