SteganoSonic sends digital information via silent supersonic waves
Wonders never cease. We first saw the magic of supersonic waves and how they developed into message and data carriers. Now we come to an age where we’re witnessing these waves transmitting digital information silently. The setup mainly included a terminal, set up in the vicinity of a speaker. Information was then sent from the directional speakers to the screen where it is displayed. When a tablet was taken into the vicinity a Web page introduction would magically pop up on the screen. One could even hear the talk delivered when he’d come near the speaker.
The source states, ‘This system is known as a parametric speaker acoustical system. Basically, SteganoSonic takes those inaudible supersonic waves and loads them with digital information, such as a website URL, and sends it to the tablet terminal.’ The system has been developed by Hitomi Tanaka, a second year student at Keio University’s environmental information studies. Another marvel arrives from Keio University.
