A Design Pattern Language to Assist the Design of Alarm Visualizations for Operating Control Systems
Display pages are sometimes too large to be viewed all at once from a single alarm display screen with a level of resolution adequate for operator's tasks.
The human operator needs to be able to navigate through large alarm displays
Use mechanisms that allow the operator specify a different degree of interest in different parts of the information. These mechanisms should allow alarm information to be moved or spatially partitioned. They should also be designed to facilitate target detection. For example, these mechanisms should be sufficiently slow when approaching the target so the operator can recognize the target.
In contrast to filtering techniques, these mechanisms combine the visualization of detail alarm information with a representation of an overview of contextual data or even the entire dataset. Discriminating interesting from contextual information is agreed as a suitable and e_ective approach to achieve visual scalability in visualization (Card, S. K., Mackinlay, J. D., & Shneiderman, B.
