Analysts are increasingly encountering datasets that are larger and more complex than ever before. Effectively exploring such datasets requires collaboration between multiple analysts, who more often than not are distributed in time or in space. Mixed-presence groupware provide a shared workspace medium that supports this combination of co-located and distributed collaboration. However, collaborative visualization systems for such distributed settings have their own cost and are still uncommon in the visualization community. We present Hugin, a novel layer-based graphical framework for this kind of mixed-presence synchronous collaborative visualization over digital tabletop displays. The design of the framework focuses on issues like awareness and access control, while using information visualization for the collaborative data exploration on network-connected tabletops. To validate the usefulness of the framework, we also present examples of how the Hugin toolkit can be used to implement new visualizations with access to these collaborative mechanisms.

  • Hugin is the name of one of the principal Norse god Odin’s twin ravens, Munin being the other one. Serving as Odin’s eyes and ears, they leave his shoulder every day to fly all over Midgard and survey the state of the world. Rather than stepping through the all requirements, I will show you a short clip which shows the requirements.\n\nDesign Requirement\n

  • Comments : Felt they were in the same space. \n\nthere was no problem communicating with the local partner. But, com-municating with remote partners was a bit hard, since we can see what they are doing, but not what they are focusing on.\nA participant also hinted at augmenting the communication with video to heighten the interactivit\n“when I view the remote person’s chart, it would be nice to see it right side up from my point of view.\n\n, we chose Skype to realize the DR7 requirement for voice support, but we found that not integrating this mech- anism into the platform seriously limited its us\n
