Interactive photographs in which still objects can be manipulated have been developed at the Massachusetts Institute of Technology MIT .

MIT said its algorithm analysed video of a still object to detect "tiny, almost invisible vibrations" that determined how it moved.

The technique, called interactive dynamic video IDV , does not require any special cameras.

It could be used to create special effects in video games or films.

"This technique lets us capture the physical behaviour of objects, which gives us a way to play with them in virtual space," said Abe Davis, a PhD student at MIT's Computer Science and Artificial Intelligence Laboratory.
