While recent advances in graphics, display, and computer hardware support ultra-scale visualizations of a tremendous amount of data sets, mechanisms for interacting with this information on large high-resolution wall displays are still under investigation. Different issues in terms of user interface, ergonomics, multi-user interaction, and system flexibility arise while facing ultra-scale wall displays and none of the introduced approaches fully address them. We introduce HIPerPaper, a novel
