LCD Display/Image Capture Device

Jon writes "Remember jokes about clueless newbies trying to fax documents by holding them up to the monitor? Perhaps they were just ahead of their time. Toshiba has developed a combined LCD/optical sensor, according to EETimes. It isn't monitor sized yet, but in a few years, perhaps?"

So much for privacy

That opens up an interesting question, can some one exploite this to see what you are doing at your desk?

ie picking your nose =]

I just want

[scorp1us]

To be able to position a webcam from computer A in front of a monitor from computer B, and reverse it. So each camera is looking at each other's monitor.

Then I want to display crap on the screen which then gets interpreted as data (Imagine a 4x4 checkerboard, black=0, white=1, so each screen displays 16 bits at a time)

Now use this to bridge two networks.

Questions: How many cells can be fit on a monitor?
How fast can you change/read the data?
Ideally if your webcam is 320x200, you could get 64kbits per flash. If you can use 4 colors instead of two, you're upto ISDN speeds...

Ah, you mean this chapter. And indeed, it's almost true now:

"Behind Winston's back the voice from the telescreen was still babbling away
about pig-iron and the overfulfilment of the Ninth Three-Year Plan. The
telescreen received and transmitted simultaneously. Any sound that Winston
made, above the level of a very low whisper, would be picked up by it, moreover,
so long as he remained within the field of vision which the metal plaque
commanded, he could be seen as well as heard. There was of course no way of
knowing whether you were being watched at any given moment. How often, or on
what system, the Thought Police plugged in on any individual wire was
guesswork. It was even conceivable that they watched everybody all the time. But
at any rate they could plug in your wire whenever they wanted to. You had to
live--did live, from habit that became instinct--in the assumption that every
sound you made was overheard, and, except in darkness, every movement
scrutinized."
