It is important to create a physically safe space in VR, free from objects and people.
We recommend having a barrier to prevent other people from walking into the VR safe space when not using VR. Tables, or ribbons can make good barriers.
If possible, run the experience away from walk-ways, doors & thoroughfares to prevent unwanted traffic in the VR safe space.

2m x 2m is enough space for a user to stretch their arms around. This is important for allowing the user to explore their new body in the mirror scenes to properly accommodate body-transfer. More space is not a bad thing.

Flat ground will ensure the user wont trip on anything. Remove all items on the floor, and furnisher in the VR safe space.

Carpet can help make sure the user wont slip, and will help prevent the hardware from being damaged if dropped.

Direct sunlight can prevent the controllers from functioning correctly. The suns infrared light will wash out the infrared LED’s on the controllers used for tracking.
Direct sunlight can also damage the inner-lenses of the headset when they are not worn. The lenses behave as a magnifying glass, which can burn the screens if left in the sun.
