...tracking the motion of the eyes. When the eye takes in a series of images of faces, objects or scenes, it spends less time on familiar elements because the brain needs less processing to interpret them. DODPI has developed an infrared camera that can track eye movement and an algorithm that can interpret it, providing clues as to whether a suspect recognizes, say, the face of a kidnapped child. Tests have reportedly achieved an 85% to 92% success rate...
...this so-called social news users, rather than a computer algorithm, determine how important or interesting the stories are, and Digg posts them on its home page accordingly. The articles are tagged with the number of "diggs," or positive votes, from readers. Click on "Switch to Cloud View" in "Upcoming Stories" to see which stories are gaining traction (the headlines appear bigger). And don't miss the new Digg Labs page, offering two visual alternatives to displaying the same info: Swarm http://labs.digg.com/swarm) which looks like a cluster map, and Stack http://labs.digg.com/stack) which resembles more...
...hope of a price drop? Thanks to computer scientist Oren Etzioni, an answer may be just a few mouse clicks away. Etzioni's site Farecast.com original name was, of course, Hamlet--provides the lowest fare on a route, a 90-day price history and, using a novel predictive algorithm, a tip to "buy now" or "wait," along with a figure indicating how confident Farecast is in its advice. (Flyers buy directly from the airlines.) Boston and Seattle are currently the only searchable points of origin at Farecast, which launched just last month, but CEO Hugh Crean says the site will...
Medical care can be a gamble--and patients often don't understand the odds. University of California researchers aim to change that, with an interactive Web-based tool that they are calling the roulette wheel. This color-coded visual model uses a computer algorithm to help patients and their doctors assess the possible outcomes of different treatments. Take the prostate-specific-antigen (PSA) test for prostate cancer, for example. The wheel for PSA screening shows a typical patient the potential harm (incontinence, impotence, death) or benefit (no symptoms) that could result from treatment following a PSA test in which high...
...Will the new revelations about the NSA tip the balance? Perhaps. According to the story, the NSA is not actually listening in on the phone calls but monitoring the patterns of calls in a kind of giant Google search, with the hope that their algorithm will detect something untoward and worth investigating. But even if your call to Aunt Sally isn't being listened to by some NSA officer, the program sounds creepy enough that no shortage of senators jumped all over it. The Republican Chairman of the Senate Judiciary Committee, Arlen Specter of Pennsylvania, said he'd subpoena...
