Move objects in Mid-Air with Sound ( interesting...!! )



A team of three Japanese engineers from The University of Tokyo and the Nagoya Institute of Technology recently unveiled an ambitious device that uses sound waves to move objects through three dimensional space. It uses four arrays of speakers to make soundwaves that intersect at a focal point that can be moved up, down, left, and right using external controls. According to one of the engineers the device uses ultrasonic speakers and is almost completely silent.
