“Using traditional cameras and algorithms,” MIT News reports, “[Interactive Dynamic Video] looks at the tiny, almost invisible vibrations of an object to create video simulations that users can virtually interact with.” Check it out:

“This technique lets us capture the physical behavior of objects, which gives us a way to play with them in virtual space,” says CSAIL PhD student Abe Davis, who will be publishing the work this month for his final dissertation. “By making videos interactive, we can predict how objects will respond to unknown forces and explore new ways to engage with videos.”
