Echolocation For Your Cell Phone

sciencehabit writes "In a few years, an iPhone app may give you a 3D layout of a room as soon as you step into it. Researchers have developed an algorithm that spits out the shape and contours of complex structures (including Switzerland's Lausanne Cathedral) using data compiled from four randomly placed microphones. The technology, which relies on the same sort of echolocation bats and dolphins use to navigate, could be used to develop more realistic echoes in video games and virtual reality simulations and to eliminate the echo from phone calls."

Re:but what of the privacy implications?!!

Lucius Fox will use it, but under protest.

Lucius Fox wouldn't be caught dead working for Apple. He wouldn't even work for the government. At Wayne Enterprises, it was setup for a short period of time, to justify a legitimate clear and imminent threat to the people, and was dismantled as soon as that threat was gone, and no "metadata" was collected; It was a targetted search. Apple collects and stores all of your searches, sells location information to the highest bidder, and could give a flying fuck through a rolling doughnut about your privacy.
