Now they can read human speech by interpreting sound vibrations, through tinfoil.

Researchers at MIT, Microsoft, and Adobe have developed an algorithm that can reconstruct an audio signal by analyzing minute vibrations of objects depicted in video. In one set of experiments, they were able to recover intelligible speech from the vibrations of a potato-chip bag photographed from 15 feet away through soundproof glass.

In other experiments, they extracted useful audio signals from videos of aluminum foil, the surface of a glass of water, and even the leaves of a potted plant. The researchers will present their findings in a paper at this year’s Siggraph, the premier computer graphics conference.

“When sound hits an object, it causes the object to vibrate,” says Abe Davis, a graduate student in electrical engineering and computer science at MIT and first author on the new paper. “The motion of this vibration creates a very subtle visual signal that’s usually invisible to the naked eye. People didn’t realize that this information was there.”

Back to the leadfoil – lined beaver den hutch, AJ, fast!

    That’s not me. My hair is about a foot and a half longer and my (full) beard about three inches longer than that guy’s (redneck, hillbilly chic). And I’m nowhere near that fat.

    I think they got the idea of reading vibrations from that movie Eagle Eye (on the surface of a cup of coffee in that case).

    I heard that the NSA plans to collect data about the eating habits of Americans by recording our farts.
