@okh I've use this feature and I've create some furniture for this.
You can try this door

Maybe someone could introduce this to make some animations when visit a home. When camera is near door the door start opening. Could be made it in AOI this kind of animation.
Off course only for those interested in this kind of virtual reality. I'm not!
