The Ishin-Den-Shin interactive installation addresses physicality and intimacy in digital audio communication. It consists of a microphone that can record sounds and transmit them through touch. Once recorded, the sound is transformed in an inaudible signal. This signal is transmitted to a person's body when holding the microphone. The signal can be transmitted by physical contact, from body to body. The recorded sound becomes audible only when touching someones ear. The sound can be heard only by the specific ear which is touched, as if the finger would be whispering the recorded sounds. Secrets, messages and whispers can then be transmitted from person to person in physical contact with each others. Bodies become a broadcasting medium for intimate, physical, sound communication.
