How could this idea work, or how does it not work?

Well... it sucks that on touch devices, half the screen if not more is taken up by the input... prompting me to think about holographic projection... which is a general coining, not necessarily "holographic" but a non-physical display.

So the idea is that you have your average phone design, in landscape mode and these two rods pop out at each end of the phone eg. left-most, right-most...

From the left, a 2D beam is projected to the right rod, then you have these beams with variable arc-radius that intersect this plane, and these areas where the "beam(s)" are focused, is where pixels change... somewhat similar to ionization of the air using lasers with 3D Aerial vision see link here:

Anyway, you can see the drawing I made of what I mean

It's just an idea... based on a flawed understanding of physics...

It's probably not safe, the energy requirements to ionize the normal air and make an image... also the resolution would probably ****

Not practical I'm afraid although there are optical projecton keyboards on the market already that possibly can be Bluetooth coupled.

Besides - the thought of two high voltage spikes coming out by accident in my pocket doesn't bear thinking about - Ouch !!!
