Ishin-Den-Shin Disney Research
The Ishin-Den-Shin technology uses a standard microphone to record audio and then converts it into an inaudible signal transmitted through the body of the person holding the microphone.
When they touch someone's earlobe, an organic speaker is formed and the sound becomes audible, effectively whispering a message into that person's ear.
The sound can be passed from person to person using any physical contact.
The technology, which was developed at Disney Research in Pittsburgh, received an honorary mention at this week's Ars Electronica Festival in Linz, Austria.
