What if we could place a mirror on the wall in VR, and then when you walk up to the mirror, you see yourself reflected, but in another world? And then, by some gesture like reaching out and touching your mirrored hand, the worlds change places. You now see yourself reflected in the place you just came from, and then when you turn around, you are in the new world that was formerly in the reflection.
I began brainstorming other situations where it is natural to want to turn around. And there it was—the elevator. Of course! We are all used to walking into a small enclosure, turning around, and then walking out into a new place moments later.
So here was the idea for my next contribution. Let’s install elevators in the Holodeck! Let’s alternate their location from level to level, encouraging the player to walk across the room, get into and elevator, and then emerge from the elevator at a new level. Then let’s repeat this several times, taking the player higher and higher from the ground floor, all the way up the roof and the wide open sky.
