Could a bag of chips being the latest tool used in the world of spying?
Abe Davis, a PhD candidate at MIT, posted a video experiment onto his Youtube channel on August 4 in which sound waves reflected off ordinary objects, such as a plant or bag of chips, were recorded and re-translated back into audio.
“In our work, we show how only using a video of the object and a suitable processing algorithm, we can extract these minute vibrations and partially recover the sounds that produced them," the researchers describe in their video.
He claims that his experiment allows normal household objects to become visual microphones.
