A Multiple View Approach to Support Data Exploration in Co-located and Synchronous Collaboration

Multi-mobile devices connected to large displays afford collaborative exploration of large data sets and make decisions. However, typical interfaces for the large, such as an overview of the whole data set, do not well designed to support collaboration and promote communication. This paper introduces one innovative multiple view on large displays that accommodate multiple individual viewports in different scales in the shared space to facilitate data exchange, data comparison, and support communication. We conducted a controlled study to evaluate our approach to traditional shared display interfaces. The experiment found our techniques improved collaboration effectiveness, and individual detailed viewports during data exploration play an essential role in collaboration. Our work can potentially improve and extend our understanding of how to visualize information on shared displays.
