Lectures 2004

You can find summary of the lectures and copies of the slides below. Copies of the slides can be downloaded only from within the HUT.FI domain.

If you are not located in the HUT network: you can for example login to the Computing Centre servers, download the files you want with a web browser (e.g. Lynx) and transfer the slides for viewing to where-ever you want. Or you can configure a ssh pipe to wwwproxy.hut.fi:80.

The lecture notes (identical to the handouts available below) can be ordered from WWWTopi. Edita will print them and they should appear to your mail box before the lectures (I hope). Edita will begin receiving material beginning from middle of September, so you can expect the first deliveries in the latter part of September.

Overview, 16 September 2004 [handouts]
Introduction to the course.
Graphical practice from past to present, 23 September 2004 [transparencies, handouts]
History of visualization and examples of visual practice.
Theory of data graphics, 30 September 2004 [handouts]
Classical theory of data graphics (or how to make elegant and effective visualizations), as presented by Edward Tufte. Main concepts are data-ink, chartjunk, multifunctioning graphical elements, data density and small multiples and aesthetics.
Vision research, human eye and perception of gray, 7 October 2004 [handouts]
A brief introduction to the history of vision research. Build of the eye, its optical properties and acuities. How the visual system perceives gray levels.
Color, 14 October 2004 [handouts]
Basics of color perception, use of color in visualizations and color reproduction
Pre-attentive features, patterns and objects, 21 October 2004 [transparencies, handouts]
Pre-attentively processed visual features and how to use them in visualizations. Gestalt laws define how people perceive patterns. Image- and structure-based theories of visual objects are introduced.
3D, 28 October 2004 [transparencies, handouts]
The depth information is obtained from various depth cues. Stereoscopic display are introduced, as well as some examples, including 3D tree and network visualizations. Sonification is introduced.
Control, interaction, problem solving, 4 November 2004 [transparencies, handouts]
Visualizations can be used to monitor systems, such as industrial processes. A modern computer interface can also be considered to be a monitoring system. Knowledge of visual monitoring models can be used to make such interfaces more effective. Interaction with visualizations is discussed, from models of data manipulation and principles of designing effective navigation systems to the structure of human memory and problem solving loop.
Mathematical methods, 11 November 2004 [transparencies, handouts]
How to project high-dimensional data to 2D or 3D. Some linear and non-linear data projection methods are introduced, with examples.
Words, text and documents, 18 November 2004 [transparencies, handouts]
How do words and images relate, how to visualize text, including document collections and computer algorithms.
Multidimensional multivariate visualization techniques, 25 November 2004 [transparencies, handouts]
Various ideas and techniques that can be used to visualize multidimensional multivariate information.
