Abstract
A novel system and method based on three-dimensional acoustic-manipulation technology is disclosed. By changing the distribution of an acoustic-potential field generated by ultrasonic phased arrays, objects can be levitated and animated. Various distributions of acoustic-potential fields can be generated in accordance with the present invention, including acoustic-potential fields having arbitrary shapes, including any three-dimensional shapes. One or more ultrasonic phased arrays surrounding a workspace can be used to generate standing waves of various shapes to provide the acoustic-potential fields. Objects can be suspended at the nodes of the acoustic-potential field so that the ultrasound distribution (i.e., the desired arbitrary shape) is visualized. The system and method can be used to realize floating screen or mid-air raster graphics, mid-air vector graphics, and interaction with levitated objects. The system and method can also be used in other applications, including cleaning applications.
