Abstract: An input device that may work in combination with an electronic device is provided. The input device is configured to input one or more adjustable parameters to the electronic device. The input device uses a plurality of concentric rotary dials to input the one or more adjustable parameters. The concentric rotary dials are co-planar with one another, and share a common center, axis or origin with one inside the other. The concentric rotary dials may have different radii from one another. Further, the concentric rotary dials have a plurality of indicia on one surface of the concentric rotary dials (such as the upper surface). Or, the indicia may be on a surface adjacent to the concentric rotary dials (such as on a non-movable faceplate). A user may move the concentric rotary dials to one or more settings in order to select one of the plurality of indicia.
