We already have the technology. It's just not cheap enough yet.
It's a cliché to say that in the past few decades "everything has become computerized" and that the power and quality of our computers has increased massively.
What hasn't changed much is the size of the interface. Sure, some of us have large monitors, or many monitors (you know who you are). But the vast majority of us interact with our computers and the Internet through a small rectangle (on a laptop, tablet or phone) that we place in front of our faces.
We take for granted that to interact with computers is to block out the world around us (and the people around us) as we focus on these glowing screens.
But after all these years of "computerization," something wonderful is about to happen: Our interface to the world of computers will leap off of the screen and onto the walls, floors, ceilings, tabletops, windows and other surfaces in our homes and offices, and in public spaces.
Here's what's happening.
