Abstract
A controller controls an ultrasonic source to cause the ultrasonic source to emit one or more sound pulses in a direction of a surface in order to obtain reflected sound pulses that are used to determine one or more properties of the surface, receive control signals from the controller, based on the one or more properties of the surface that are determined, and emit ultrasonic sound waves in the direction of the surface based upon the control signals. The ultrasonic sound waves exert a force which causes visible particles within a region proximate the surface to move to achieve a desired appearance with respect to the surface.
