A new technology from Disney can turn someone’s finger and ear into a speaker.
It appears to make sound come from nowhere and could be seen as magical to someone who didn’t know the technology existed.

By taking sound recorded from a microphone and making the sound waves into a modulated electrostatic field on the skin of the person holding the microphone, the sound can then be heard when the person touches their own or someone else’s ear.

The signal creates a vibration in the earlobe that allows the person whose ear is being touched to hear the looped recorded sound.

The sound waves are inaudible unless the person transmitting them is touching someone’s ear, but the energy of the waves themselves can be transmitted to another person through any physical contact.

It was developed by Disney Research in Pittsburgh, Pennsylvania.

The installation and technology is called Ishin-Den-Shin, which is a traditional Japanese concept of unspoken interpersonal communication and translates roughly as “what the mind thinks, the heart transmits.”

Disney’s installation got an honorary mention at the Ars Electronica Festival held in Linz, Austria.
