Agenda: 08/26/2013 • Discuss information visualization methods. • Tables, diagrams, charts, bullet points • Words vs. pictures vs. numbers • Visualization that must stand on its own vs. those accompanied by talk. • Evaluate information visualization methods. • Look for level of content. Does it transmit rich content? • What are the strengths/weaknesses? • Are there other ways that the material could be presented? • Generate guidelines for information visualization.
To visualize means… • To form a mental image of… • To make perceptible to the mind or imagination. • Visualization is a cognitive activity; when we visualize we perform a mental process.
Information visualization • Definitions of information visualization related to technology: • The study of how to effectively present information. • The use of computer-supported visual representations of abstract data to amplify cognition (from Readings in Information Visualization). • The purpose of information visualization is to help people think by providing different representations of data for differing contexts. • Information visualization should help: • Speed up understanding and resultant actions. • Encourage innovative ways to think about the data.
Information visualization is design, not art • Art and design are not the same. • Art is valued for its originality and expressiveness. • Art is valued for pushing the bounds of accepted norms and potentially expanding the definition of those norms. • Design is valued for its fitness to a particular user or task. • Design is valued for its effectiveness and use. • Design requires that the designer know the audience, use, task, and objectives to be accomplished.
