While analyzing complex graphs, especially in collaborative work with other persons, large, high resolution displays offer the enormous advantage to display the graph very detailed in front of a high number of people to ease discussions. Compared to work at a single working place, the lack of manipulating data or create annotations without disturbing other users, there is a disadvantage. Relief can brought by separate the whole view from personal views on additional devices like tablets.
In this diploma thesis interaction concepts to record personal annotations and manipulate graphs will be developed to emerge easier discussions with other users. Here a large, high resolution display will be used for displaying the whole graph, while personal tablets enable the visualization and manipulation of additional information and views. The tablet position in space will be used to match the personal view to the the big overview.
