VOYAGER: Automatic Computation of Visual Complexity and Aesthetics of Graph Query Interfaces

People prefer attractive visual query interfaces (vqi). Such interfaces are paramount for enhancing usability of graph querying frameworks. However, scant attention has been paid to the vi- sual complexity and aesthetics of graph query interfaces. In this demonstration, we present a novel system called voyager that leverages on research in computer vision, human-computer interaction (hci) and cognitive psychology to automatically compute the visual complexity and aesthetics of a graph query interface. voyager can not only guide vqi designers to iteratively improve their design to balance usability and aesthetics of visual query interfaces but it can also facilitate quantitative comparison of the visual complexity and aesthetics of a set of visual query interfaces. We demonstrate various innovative features of voyager and its promising results.
