TrapezoidBox
  : Dynamic Query Interface for Spatial Proximity Query with Degree-of-Interest Varied by Distance to Query

  
  Motivation

    Dynamic queries are effective tools for interactively querying large datasets. They continuously update the datafiltered from the database and visualize. Many information visualizationresearch and commercial systems adopted dynamic queries as an essential component.
    In this paper we present an interactive query interface called "TrapezoidBox" to support spatial proximity queries where users' degree of interest varies depending upon the degree of separation from the point of interest. Spatial proximity queries are commonly built in information seeking tasks especially on online maps. If not impossible, it is hard to formulate spatial proximity queries using existing dynamic query widgets suchas range sliders. TrapezoidBox allows users to easily build spatial proximityqueries by interactively adjusting a trapezoidal function.
    Our controlled userstudy results show that TrapezoidBox has several advantages over a baseline interface with range sliders.
