A method, system, and computer program product for human-machine interface devices. Embodiments commence upon receiving a set of dimensions then generating a first interactive user interface comprising a series of concentric rings corresponding to the set of dimensions. The concentric rings comprise a series of wedges representing dimension values. A second interactive user interface is displayed, wherein the second interactive user interface comprises at least some of the set of dimensions, and wherein a user interaction upon the first interactive user interface causes a change in the second interactive user interface. Embodiments can include a selector to select a wedge and/or a slice, and the second interactive user interface can be presented as a table. User interaction upon the second interactive user interface is reflected simultaneously on the first user interface and user interaction upon the first user interface is reflected simultaneously on the table.
