A Query Description Model and its Implementation as an Interactive Query Tool for Visualization Systems

摘要

In this paper, we describe the development of a query definition support environment for Queryball, which is a new style of interaction tools developed at Nara Women's University. Queryball is a translucent ball, which has query conditions and visualization methods. Users can apply a query just inside the ball, and modify the area where the query is applied by moving and overlapping Queryballs. We propose several query models for Queryball using a description model named visualization pipeline. Based on the models, we developed a Queryball definition support environment with two description modes; one is to use a script language, the other is to use a visual programming tool. By using the visual programming tool, user can browse and edit the definitions of Queryball easily, intuitively, and graphically.
