POSTER:computer news || THE MECHANISM OF EAVESDROPPING
DATE:2014-08-05
A sound wave is transmitted in space by mechanical vibrations of molecules created by some source. The source wave propagating in space, can transmit vibration energy to another body, which, in turn, begins to wave, and, as Adobe, Microsoft and MIT researchers were able to show secondary fluctuations may be overheard.
Researchers have developed an algorithm that allows us to identify the sound by vibration analysis of the object captured on video with a high frame rate. For example, in one experiment, human speech was heard from the surface of the packaging of potato chips at a distance of 4.5 meters, in other experiments used aluminum foil and houseplants.
It is hoped that the technology will be used in research, and not to spy.
