Where are we losing the link? It is at the screen! Computer screen.
All that is processed and stored in computers is in digital form. Every computer basically does same thing. Viz., convert any information into bit by bit and manipulate it as per instructions or store it.
Imagine a case: Suppose, you want to print "xyz" on a screen. x, y, z each character is represented by a bit in memory. But, when you show it, the video adapter should transform this single bit with the formatting information, to a bit map for required number of pixels. So, this is what is loss of digitality, also it becomes complex and heavy in terms of memory consumption. Suppose, user wants to select only x and y from this "xyz", and paste it on to screen on some other PC, is it possible(hete, I am jsut extrapolating user needs into the future)?
If we design a device which can read say, "xy" from "xyz" displayed on the screen, the device has to scan the image imprinted in the screen and using some algorithm, it should interpret it as "xy". That means the reader device has to be made smarter. Why not making the screen smarter if it is easier? With each character, let us insert the ASCII value (of the character) inside one of the pixels directly, you can make it more readable. This is easier than image processing because, the ASCII value of the character being displayed is readily available in the memory.
But, a standard has to be developed for that. Decision on which pixel repsresents ASCII value of the character, has to be taken.
If this feature is inducted, it will help all data transfers which need user interactions. This might sound peculiar at first time. But, I think if such a technology is developed, some of the latent requirements of customers will be satisfied.
