Information Visualization, Self-Ethnography and You 20120127 MARIUS WATZ - AHO INTERACTION DESIGN INFORMATION VISUALIZATION, SELF-ETHNOGRAPHY AND YOU An introduction to Information Visualization, including a (very) brief history, recent trends and the notion of Data Literacy. Practical application: Self-Etnography, also known as personal data logging. Easily available tools, relevant existing projects and suggested practices. TWITTER.COM/MARIUSWATZ FLICKR.COM/PHOTOS/WATZ UNLEKKER.NET VIMEO.COM/WATZ GENERATORX.NO DELICIOUS.COM/GARUDA WORKSHOP.EVOLUTIONZONE.COM INFORMATION VISUALIZATION » The practice of interpreting data and presenting it visually in ways that bring to light patterns of information, so as to enable the discovery of knowledge. » Visualization is often seen as a way of convincing an audience. But is also a powerful for discovering new knowledge. » The aim of visualization is to reveal (Manuel Lima) INFORMATION VISUALIZATION » History: Maps are as old as written culture. Infoviz as we know it dates back to late 1700s. » Almost all common chart types were pioneered before 1810 » Early heroes: William Playfair, Charles Minard, Florence Nightingale Willam Playfair Statistical Breviary (1801) Generally considered the first pie chart Willam Playfair Trade balance, England and Denmark / Norway Florence Nightingale, 1858 Causes of mortality in the Army Charles Minard, 1869 Chart of Napoleon’s disastrous march on Moscow Simultaneous display of multiple variables (location, troops, temperature) COMPUTERS & VISUALIZATION » A computer = a machine that computes.

They include ratios and proportions (static and dynamic, geometric, arithmetic and harmonic progressions) expressing symmetry and self-similarity principles in spatial-metric terms, but also principles of nonlinearity and complexity by symmetry-breakings within non-metric systems. The first part explains geometric and numeric relational figures/sets as taken for “principles of beauty and primary aesthetic quality of all things” in classical philosophy, science, and architecture. These progressions are guided by certain rules or their combinations (codes and algorithms) based on principles of regularity, usually directly spatially reflected. Conversely, configurations representing the main subject of the following sections, could be spatially independent, transformable, and unpredictable, escaping regular extensive definitions. Their forms are presented through transitions from scalable to no-scale conditions showing initial symmetry breakings and abstractions, through complex forms of dynamic modulations and variations of matter, ending with

  • What Is Visualization? Published in Visual Studies Journal (Taylor & Francis, 2011)
    1/26 Lev Manovich www.softwarestudies.com What is Visualization? Published in Visual Studies journal (Taylor & Francis, 2011). Abstract The article proposes that the practice of information visualisation (infovis) from its beginnings in the second part of the eighteenth century until today relied on two key principles. The first principle is reduction. Infovis uses graphical primitives such as points, strait lines, curves and simple geometric shapes to stand in for objects and relations between them. The second principle is the use of spatial variables (position, size, shape and, more recently, movement) to represent key differences in the data and reveal patterns and relations. Following this analysis, I discuss a more recent visualisation method which we can call ‘media visualisation’: creating new visual representations from the actual visual media objects (images, video) or their parts. The article analyses the well‐known examples of artistic visualisations that use this method: Listening Post (Ben Rubin and Mark Hansen, 2001), Cinema Redux (Brendan Dawes, 2004), and Preservation of Selected Traces (Ben Fry, 2009). I further suggest that media visualization method is particularly relevant for humanities, media studies and cultural institutions. Using the actual visual artefacts in visualisation as opposed to representing them by graphical primitives helps the researcher to understand meaning and/or cause behind the patterns she may observe, as well as discover additional patterns. To illustrate this idea, I present the examples of projects created in our lab at UCSD (Software Studies Initiative, softwarestudies.com). Founded in 2007, the lab develops on techniques and software to allow interactive exploration of large sets of visual cultural data using media visualisation approach and supervisualisation systems such as 287 megapixel HIPerSpace.

  • Contexts for Conservation 20132013 National Conference --- Adelaideadelaide 2323---- 25 October
    ContextsContexts for Conservation 20132013 National Conference --- AdelaideAdelaide 2323---- 25 October Data visualisation: a new tool for conservation Peter Shaw, National Archives of Australia Abstract In the National Archives of Australia we are flooded with information in databases, spread sheets and images. We use this data to identify, understand and retrieve collection items. Analysis of collections through physical surveys and database interrogations is used to establish conservation priorities and undertake identified projects. This methodical approach can be time consuming and labour intensive. Web based word searches can be a little like viewing the world through a letterbox. By harnessing data sets we can use visualisation techniques to look at everything and reveal associations that can be used for preservation and access purposes. Visualisation can be a useful tool for access, preservation planning and data entry quality. Five years ago, the Archives commissioned a project called the Visible Archive, in which visualisation techniques were applied to large Archives datasets to develop ways of exploring and understanding the contextual relationships of records. The Archives is currently supporting a project to explore content based image retrieval that will gather like images in a data set. For conservators and archivists this will have the benefit of identifying duplicate images; associating images that may be split across collections and allowing data entry comparison for consistency, accuracy and completeness. I aim to demonstrate that with available data sets conservators can use visualisation processes to identify conservation priorities in image collections and target records at risk and known to be deteriorating. Introduction My aim is to propose a different approach to the conservation and management of photographic collections.

  • Aesthetics Framework in the Design Knowledge Modelling of Data Visualization
    Journal of Advances in Information Technology Vol. 11, No. 1, February 2020 Research on the Application of Function-Technology- Aesthetics Framework in the Design Knowledge Modelling of Data Visualization Chiung-Hui Chen Asia University, Taichung, Taiwan Email: [email protected] Abstract—Data visualization is the combination of design boring or extremely colorful and complex data aesthetics and rigorous science, and the selection on visual visualization patterns. Kalfoglou et al. [1] proposed that representations is ultimately determined by the integration design knowledge is important for the design industry, of aesthetics and design information. For the design design education, and related technologies. Design knowledge and experience on this aspect is rather deficient, knowledge refers to exploring solutions in a wide range designers often cannot keep the balance between design and of possibilities in known and unknown fields, as its value functions. This study is aim at developing a data is different from objective technical data. Therefore, the visualization design method targeted to design on design design education of data visualization cannot neglect the education, to enable students to have specific methods to visual basis, and must return to communication; if it only follow when engaging in information design and to provide reference to designers for design. The content analysis focuses on colorful and complex data visualization method is employed to discuss relevant literature and to patterns, it will produce invalid communication. summarize the data visualization design cases, and the data To sum up, how to effectively organize and use data visualization design patterns are established to facilitate design is a very important topic in the current mass learning and knowledge inheritance of data visualization production of information.
