Abstract:
The emission of variable ultrasonic sound waves from a plurality of sound sources is controlled based on controlled signals generated by a controller. The plurality of sound sources emit ultrasonic waves towards a surface based on the control signals, creating a force which causes particles within a region proximate the surface to move in a desired manner with respect to the surface. The movement of the particles with respect to the surface changes the appearance of the surface. In this manner, the appearance of the surface may be changed in a desired manner to suit needs for home automation and security.
