Permeable, mid-air displays, such as those using fog or water mist are limited by our ability to shape and control the aerosol and deal with two major issues: (1) the size and complexity of the system, and (2) the creation of laminar flow, to retain display quality. Here we present SonicSpray, a technique using ultrasonic Bessel beams to create reconfigurable mid-air displays. We build a prototype from low-cost, off-the-shelf parts. We explore the potential and limitations of SonicSpray to create and redirect laminar flows of fog. We demonstrate a working prototype that precisely controls laminar aerosols
through only 6x6 ultrasound transducers array. We describe
the implementation steps to build the device, verify the control and projection algorithm for the display, and evaluate its performance. We finally report our exploration of several useful applications, in learning, entertainment and arts.
