Anchor Lede: Computers can search for words very quickly, but when it comes to images our brains are much better. So engineers are exploring how we can help computers.
Randy Atkins: If you’re web surfing for, say, a “beautiful” or “funny looking” picture, search engines have a tough time knowing exactly what you want. So Paul Sajda, a Columbia University biomedical engineer, is monitoring people’s brain activity as he shows them pictures at the rate of ten a second.
Paul Sajda: You might see an image and realize, “Ooh, that’s interesting.” You might not be able to then, in that fraction of a second, really describe it in detail. You just know that it caught your attention.
