Task: Difference between revisions

Revision as of 11:32, 26 August 2009

There are a number of different task taxonomies in InfoVis at different levels of granularity.

Task Taxonomy of Relational Information Displays

by: [Zhang, 1996] based on [Carswell and Wickens, 1988]

There are three major types of display tasks:

information retrieval
comparison
information integration

High-level tasks / purposes / goals of Visualization

Sources: [Schumann and Müller, 2000], [Keim et al., 2006]

On the interplay between task and representation

Thus, although there are no best displays that are efficient for all types of tasks, there is a correct or incorrect mapping between the representation of a display and the structure of a task.
