That's a good point, and something my Vive setup has been struggling with. My play area is just a little bit too small, so I see the boundaries a lot. It's not as bad as not having them and periodically punching a wall or walking in to the couch, but it's kind of a bummer to see it and go, "oh, right, I'm in my living room," especially in some of the much more immersive experiences.
