There is a tv show called Psycho Pass which is set in the near future. I bring it up as it has a wristwatch in it where you press a button on it and then it projects a larger screen out of it (maybe 6"x4") about six inches away from the wrist. Sensors then allow you to interact with the screen.
No idea what the tech behind that could be. Closest I could come up with is the watch shooting out a fog when you want the virtual display.
I definitely thought the Apple Watch would be a little bit further ahead of other smartwatches than it is. I thought it would be to other smartwatches what the iPhone was to other smartphones at the time.
So, I was thinking that the Apple phone would be something like this projected keyboard (http://en.wikipedia.org/wiki/Projection_keyboard) but as a touchscreen that is suspended in mid air.
