Abstract
An appliance and method of operation is provided. The appliance may include an outer casing, a user interface, and a controller. The outer casing may define an enclosed volume. The user interface may be mounted to the outer casing to include a light projector and a translucent diffuser disc. The light projector may be positioned within the enclosed volume and include a plurality of discrete segmented light emitting diodes to each selectively emit one or more discrete light emissions. The translucent diffuser disc may be positioned between the light projector and the outer casing. The diffuser disc may include a continuous outer surface aligned with the light projector to display the one or more discrete light emissions as a visually continuous pattern. The controller may be operably connected with the light projector and configured to determine the visually continuous pattern displayed at the continuous outer surface.
