Can the quality be brought up enough to have a combination display and
window? Without compromising either.
Howzbout display panels instead of drywall?
I'll have some difficulty getting used to the future, but I am looking
forward to bigger and better displays.
3M developed something very nearly a combination of touchscreen and
display projector in the late '90s. I was working for the applied
archaeology labs at University of Texas and we got a demo/market-test model.
It was one of those things that everybody went "Ooooh SHINEY", got
all excited, then had zero use for. Accordingly, my memory of it is
very hazy. Mostly what I remember was that the Windows-only software
was a clusterf**k to use and nobody would sit still to get trained to
it, so the thing sat in the corner.
It looked like a big whiteboard on wheels, connected via serial(?)
cable to the computer. The projector displayed the Windows desktop on
the board and there were special markers to draw with. The board
recorded marker strokes to something resembling a PowerPoint
presentation. IF, that is, I remember correctly.
Does anyone remember such a thing? Did 3M ever bring it out as a
product?
