ABSTRACT
In this paper, we propose a mathematical model to measure the visual stability of dynamic graph drawings. Our approach was validated through a study, which combined the use of questionnaires and an eye-tracking device. The participants of the study had to track members of a software development community over five periods of time in three different dynamic graph drawings. The results suggest that dynamic graph drawings making use of fixed positions are more efficient in the visual search but are limited in the recognition of single elements. On the other hand, dynamic graph drawings with the minimal changes or a constant structure improve the recognition of single elements but lose efficiency in the visual search.

Using Visual Stability to Support Search Efficiency and User Experience in Dynamic Graph Drawings
ENIC '15: Proceedings of the 2015 Second European Network Intelligence ConferenceIn this paper, we present a set of algorithms to compute a foresighted graph layout. We aim to produce a dynamic graph drawing that allows the users to track actors in a dynamic social network, supporting a satisfying user experience along with an ...
Dynamic graph models
Research in graph theory has focused on studying the structure of graphs with the assumption that they are static. However, in many applications, the graphs that arise change with time, i.e., they are dynamic in nature. This is especially true of ...
