Research on Visualization Nonverbal communication, right-brain processing, mindmaps, art-talk, symbol processing, semiotics Tuesday, August 07, 2001
This is awkward. I used the right-click to capture several paragraphs from a book on the web. Last in/first out. So you start with the final chunk and read backwards to the first. Hmmm. How to take coherent notes?

3. The Information Access Process A study of business analysts [oday93] found three main kinds of information seeking tasks: monitoring a well known topic over time (such as researching competitors' activities each quarter), following a plan or stereotyped series of searches to achieve a particular goal (such as keeping up to date on good business practices), and exploring a topic in an undirected fashion (as when getting to know an unfamiliar industry). Although the goals differ, there is a common core revolving around the information seeking component, which is our focus here.

2. Human-Computer Interaction Aside from using icons and color highlighting , the main information visualization techniques include brushing and linking [eick95][tweedie94], panning and zooming [bederson96], focus-plus-context [leung94], magic lenses [bier94], and the use of animation to retain context and help make occluded information visible [robertson93][card91]. These techniques support dynamic, interactive use. Interactivity seems to be an especially important property for visualizing abstract information, although it has not played as large a role within scientific visualization.

2. Human-Computer Interaction What makes an effective human-computer interface? Ben Shneiderman, an expert in the field, writes (p.10) [shneiderman97]:
Well designed, effective computer systems generate positive feelings of success, competence, mastery, and clarity in the user community. When an interactive system is well-designed, the interface almost disappears, enabling users to concentrate on their work, exploration, or pleasure. posted by jay cross on 8:26 PM | link
