Summary: Providing insight in complex networks or graphs with multivariate data is
one of the main challenges for visual analysis today. Much work has been done
for visualizing information on nodes, but the space in between has mostly not
been used yet. We present the current progress of our approach for using this
free space to visualize additional information. We developed two techniques
called Partially filled Bars and Bars of Varying Height. Both techniques enable
presenting multiple attribute values on the edges of a network simultaneously.
We briefly discuss first use cases for such interfaces as well as advantages
and disadvantages of both techniques. For proof the concept, a preliminary
evaluation has been performed. The results show, that both techniques are
promising for many use cases.

Summary: Collaboration between users of a system is often a crucial factor for
reaching given goals in an effective and efficient way. However, in many
application domains, the current systems do not sufficiently support
collaborative work (sometimes they even don't support it at all). One good
example is geographical information systems (GIS), that usually only follow an
one user at one time approach. In this paper, we present the development of a
scalable Multi-user Geographical Information System (MuGIS). With MuGIS it is
now possible to integrate large display environments with mobile smart devices
for remote control. The system is deployed as a client-server architecture. It
uses the NASA World Wind Java framework and SOAP web services for
communication. On the client side, all common mobile smart devices are
supported. The underlying concept provides different user roles and multi-user
identification.
