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
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, 10 September 2003 [transparencies, handouts]
- Introduction to the course.
- Graphical practice from past to present, 17 September 2003 [transparencies, handouts]
- History of visualization and examples of visual practice, data
- Theory of data graphics, 24 September 2003 [transparencies, 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, 1 October 2003
- 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, 8 October 2003
- Basics of color theory, color in visualization and color reproduction.
- Pre-attentive features, patterns and objects, 15 October 2003
- 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
- 3D, 22 October 2003
- 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, 29 October 2003 [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, 5 November 2003 [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, 12 November 2003 [handouts]
- How do words and images relate, how to visualize text, including
document collections and computer algorithms.
- Animation (Jyrki Hokkanen, CSC), 19 November 2003 [PDF,
- Introduction to computer animation.
- Multidimensional multivariate visualization techniques, 26
November 2003 [handouts]
- Various ideas and techniques that can be used to visualize
multidimensional multivariate information.
- Information workspaces, sonification, conclusions, 3
December 2003 [handouts]
- Infosphere and information workspaces are task-oriented caches to
access the infosphere. Basics of the use of nonspeech audio to convey
information, or sonification, are discussed and a very short summary
