Sure - this makes a great deal of sense. The brain discards all but
the last pico-fraction of the data actually presented to it, focusing
instead on the "important bit." It would be great if we could cut out
the middle man and just poke a bit of recognition equipment in the
right way. So far as technologies that actually accomplish this,
natural language does a pretty amazing job. The memory, I think, of
particularly vivid things I've read is about as rich as the
recollection of things that actually happened.
