声悬浮可以在没有任何物理接触的情况下将毫米级的物体保持在半空中。这种能力已经被利用来创建显示，因为能够定位半空中的物理体素能够实现丰富的数据表示。然而，大多数时候，声悬浮的有趣特性没有被利用。声悬浮是无害的，声音在物体周围衍射，因此我们可以将我们的手插入悬浮器内，触摸悬浮的粒子，而不会对我们产生有害影响。在这个演示中，我们展示了与声悬浮颗粒的更有形的相互作用，通过将声学透明结构穿过颗粒，使用可穿戴悬浮器在半空中操纵颗粒，或者通过直接操纵移动多个颗粒。我们希望这个演示能提供一个更实际的声悬浮体验。由于所有展示的设备都是自己动手做的，我们鼓励参观者进一步试验声悬浮。
Acoustic Levitation can hold millimetric objects in mid-air without any physical contact. This capability has been exploited to create displays since being able to position mid-air physical voxels enables for rich data representations. However, most of the times interesting features of acoustic levitation are not exploited. Acoustic Levitation is harmless and sound diffracts around objects, thus we can insert our hand inside the levitator and touch the levitated particles without harmful effect on us. In this demo, we showcase more tangible interactions with acoustically levitated particles by passing acoustically-transparent structures through the particles, manipulating particles in mid-air with wearable levitators or by moving multiple particles with direct manipulation. We hope that this demo provides a more tangible experience of acoustic levitation. Since all the presented devices are Do-It-Yourself, we encourage visitors to experiment further with acoustic levitation.
