Visual 3D Querying of Spatio-Temporal Data

Visual interfaces are very important for human interactions in cyberworlds. Visual querying should be one of the basic tools for data mining and retrieval in cyberworlds. In this paper, function-based modeling of spatio-temporal range queries is described. It allows for creating an intuitive visual interface using 2D projection of 3D query shapes. The proposed approach combines visualization of time-dependent data with visualization of the range query formulation employing very compact function-based query model. It is also shown that the proposed geometric model makes constructing the queries on spatio-temporal attributes more intuitive, and allows for posing temporal range queries of any shape
