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
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.
