Details on demand
Jump to navigation Jump to search
The details on demand–technique allows interactively selecting parts of data to be visualized more detailed while providing an overview of the whole informational concept.
We distinguish between the refinement methods detail on demand, where the user requests greater detail, and progressive refinement, where the system transmits and displays more detail automatically. Both methods can be combined, too. In order to save bandwidth, it is essential that only differential data are transmitted.
