2 What is Tufteism?The study of the philosophies of Edward Tufte.
3 Who is Edward Tufte?Professor of statistical evidence and information design at Yale UniversityTeaches:statistical evidenceinformation designinterface designKnown primarily for his self-published books on information design, which have received more than 40 awards for content and design.
4 Tufte Books Published in 1983 The classic book on statistical graphics, charts, tables. Theory and practice in the design of data graphics, with detailed analysis of how to display data for precise, effective, quick analysis. Design of the high-resolution displays, small multiples. Editing and improving graphics
5 Tufte Books Published in 1990 This book celebrates escapes from the flatlands of both paper and computer screen, showing superb displays of high-dimensional complex data. The most design-oriented of Edward Tufte's books.
6 Tufte Books Published in 1997 Visual Explanations: Images and Quantities, Evidence and Narrative is about pictures of verbs, the representation of mechanism and motion, process and dynamics, causes and effects, explanation and narrative. Practical applications and examples include statistical graphics, charts for making important decisions in engineering and medicine, technical manuals, diagrams, design of computer interfaces and websites and on-line manuals, animations and scientific visualizations, techniques for talks, and design strategies for enhancing the rate of information transfer in print, presentations, and computer screens.
7 How does he relate to interface design? Interface designers organize information and design a means to present it.Tufte believes that the way we choose to organize and present information can have a dramatic effect on how the reader/user interprets it.
8 Presentation of Information has a Dramatic Effect on How It is Interpreted. The Challenger Shuttle explosion of 1986.Information existed that should have prevented launch.Lauch occurred.Shuttle exploded.

12 Escaping FlatlandAll communication between a viewer and an image occurs on a 2 dimensional surface.Most interesting data is multivariate in nature.
13 How to Escape Flatlands How to increase the number of dimensions that can be reproduced on flat surfaces?High information resolutionUse small multiplesCompromise – what non-essential information can you get rid of to incorporate data from other dimensions?
