At our lab today we were discussing how various everyday activities will change when everybody has those future Augmented Reality wearable specs. I was speaking enthusiastically about all the cool things we will be able to do that we can’t do now.
“But what about selfies?” one of the students objected. “If you are wearing the camera on your face, how can you take a picture of you and your friend together?”
I took a small coin-sized object out of my pocket and held it up at arm’s length. “This is my future camera,” I said. “And I can also preview what the selfie will look like, because I can see anything I want through my wearables.”
The point was that a camera can be as small as you want, once it no longer needs to be attached to a physical screen. When you are wearing those future specs, the “screen” will be wherever you want it to be.
