迪士尼研究发布“心领神会”的触感传声技术

#研究分享#迪士尼研究发布了一项名为“心领神会”的技术,将优先应用在麦克风上。1)技术的原理是A君的音讯透过麦克风会被记录下来,此时他用指尖触碰B君的耳朵,就可以无声传播声音;2)此技术还能应用到物件触碰上,人们一旦用手触碰某一安装了该装置的物件,就能透过触感心领当中包含的信息;

原文标题:Ishin-Den-Shin

Ishin-Denshin is a four-kanji mantra which represents the traditional Japanese concept of interpersonal communication through unspoken mutual understanding. It literally translates as “what the mind thinks, the heart transmits.” Sometimes explained in English in terms of “telepathy” or “sympathy”, the term is also commonly rendered as “heart-to-heart communication” or “tacit understanding.” [Wikipedia]

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.

 

A Shure 55 microphone is connected to a computer’s sound card. The microphone is recording as soon as a sound that is a higher amplitude than a set threshold is sensed. The computer creates a loop with the recording which is then sent back to an amplification driver. This amplification driver converts the recorded sound signal into a high voltage, low current (300 Vpp, 50 uA) inaudible signal. The output of the amplification hardware is connected to the conductive metallic casing of the microphone via a very thin, almost invisible wire wrapped around the microphone audio cable. When holding the microphone, the visitor comes in contact with the inaudible, high voltage, low power version of the recorded sound. This creates a modulated electrostatic field around the visitors’ skin. When touching another person’s ear, this modulated electrostatic field creates a very small vibration of the ear lobe. As a result, both the finger and the ear together form a speaker which makes the signal audible for the person touched. The inaudible signal can be transmitted from body to body, using any sort of physical contact.
