Concentric Sliders to Display Partial Satisfaction of Query Criteria

This paper describes a new approach called concentric planar slider to visually build queries and to pilot a data view. The purpose of this approach is to go beyond the binary satisfaction of the query criteria(satisfied vs. not satisfied). This UI control helps the user to know to what extent the dataset elements satisfy them. Two interactive sliders are combined in a planar setting. This plane is split into concentric zones that are associated to decreasing degrees of satisfaction of the query criteria. Various (potentially asymmetric) rules can be defined to express the non-satisfaction of a given criterion. These theoretical concepts have been implemented in a prototype whose main features are also described.
