Project Overview

This project is a cooperation between Technische Universität Dresden and University of Rostock. It is supported by the DFG (Project numbers: DA 1319/3-1, SCHU 887/14-1).

Graphs have an important role in different application areas. For example in social network analysis or to depict biological relations in systems biology. Known visualization approaches focus primarily on graph exploration and use mouse interaction techniques. The goal of this project is to support exploration and manipulation similarly through multiple interactive surfaces and novel interaction modalities.

The research foci are the following:
  • Merging of exploration and interactive manipulation:
    Graphs are often interactively created. One example is process modeling. In other applications graphs are being visually explored. For example in the area of social networks. It shall be analyzed how far interactive displays can bring together exploration and interactive manipulation to open new possibilities for novel applications.

  • Merging of interaction and information presentation:
    Modern interactive displays support both presentation and interaction and thereby reduce the cognitive distance between input and output. This potential shall be used to allow a continuous transition between presentation and interaction and to provide novel options for direct manipulation and exploration of complex graphs.

  • Combination of multiple displays and interaction techniques:
    The use of tabletops and small additional displays (magic lenses) simultaneously enables the combination of views with different resolutions with multiple interaction techniques. This potential shall also be used for the analysis of complex graphs.
