TED: New video technology that reveals an object's hidden properties | Abe Davis

The video explores the concept of capturing subtle motions that are invisible to the human eye using technology developed at MIT. This technology, called the emotion microscope, amplifies these motions in videos, allowing us to visualize phenomena like a pulse or breathing. The video further delves into the idea of using video to capture sound vibrations, effectively turning objects into visual microphones. Through various experiments, the challenges and potential of this technology are discussed, highlighting its applications in fields like surveillance and interactive simulations. The video concludes by emphasizing the future potential of this technology in capturing and interacting with real-world objects.

What is the primary function of the 'emotion microscope' developed by MIT?

• To amplify subtle motions in videos

• To detect colors in low light

• To record audio from a distance

• To enhance video resolution

How does the concept of a visual microphone work?

• By converting sound into light signals

• By using video to capture sound vibrations

• By recording sound directly with a microphone

• By amplifying sound through speakers

What was a significant achievement in the early experiments with visual microphones?

• Capturing high-resolution images

• Recovering intelligible human speech from silent video

• Detecting colors in complete darkness

• Recording sound from underwater

What is a key factor that affects the success of visual microphone experiments?

• The color of the object

• The distance of the object from the camera

• The temperature of the environment

• The type of sound being played

What is the purpose of using video vibrations to interact with objects?

• To create 3D models

• To simulate how objects respond to new forces

• To enhance video quality
