Lectures

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.

The lecture notes (identical to the handouts available below) can be ordered from WWWTopi (I think). Edita will print them and they should appear to your mail box before the lectures (I hope). Edita will begin receiving material beginning from 16 September 2002, so you can expect the first deliveries in or around 21 September.

Overview, 11 September 2002 [PDF, handouts as gzipped PS]

Overview of the field of visualization.

Graphical practice from past to present, 18 September 2002 [PDF, handouts - gzipped PS]

History of visualization and examples of visual practice, data integrity.

Theory of data graphics, 25 September 2002 [PDF, handouts - PDF, handouts - gzipped PS]

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, 2 October 2002 [PDF, handouts - PDF, handouts - gzipped PS]

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 theory, color in visualizations and color reproduction, 9 October 2002 [PDF]

A brief introduction to color theory. Examples of commonly used color spaces and color scales. Corlor reproduction covers issues on what should be taken into account when designing visualizations used on different media.

Pre-attentive processing, gestalt laws, visual objects, 16 October 2002 [PDF, handouts - PDF, handouts - gzipped PS]

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, 23 October 2002 [PDF, handouts - PDF, handouts - gzipped PS]

The depth information is obtained from various depth cues. Stereoscopic display are introduced, as well as virtual environment systems. Some examples is given on visualizing trees and networks in 2D and 3D.

Control, interaction, problem solving, 30 October 2002 [PDF, handouts - PDF, handouts - gzipped PS]

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, 6 November 2002 [PDF, handouts - PDF, handouts - gzipped PS]

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, 13 November 2002 [PDF, handouts - PDF, handouts - gzipped PS]

How do words and images relate, how to visualize text, including document collections, computer algorithms and program code.

Multidimensional multivariate visualization techniques, 20 November 2002 [PDF, handouts - PDF, handouts - gzipped PS]

Various ideas and techniques that can be used to visualize multidimensional multivariate information.

Information workspaces, sonification, conclusions, 4 December 2002 [PDF, handouts - PDF, handouts - gzipped PS]

Infosphere and information workspaces, sonification. Some concluding remarks.
