1. Note: next week before class SAS visitors to lab…oct 25, guest speaker Todd Barlow

2. One-minute paper debriefing
Big Points:
Web is a mess—solutions: interface design guidelines; improve basic human capabilities?
Info is a change in HUMAN knowledge state
Info seeking is purposeful.
There is lots of basic R&D to do on intelligence amplification, affective computing, search evaluation.
Smartcard security and user trust
The usefulness of hypertext may not yet have been fully tapped

Questions:
Info science is multi-disciplinary—where do I fit?
Can computers evolve into problem-solving appliances that are simply part of the environment?
How to design interfaces to accommodate human limits, differences?
Not convinced that linear progression is best/most logical for information seeking?
How can we ms reaction knowledge without testing at that level?
How did Xerox PARC start? (see Rogers)
Is it possible to be computer literate but wrongly? (e.g., experience with a bad interface keeps one from learning a new one)…(cognitive inertia)
How much IR is text based and how is non-text IR different?
Are gaps in skill/knowledge across individuals/groups inevitable?

3. Finish  Information-seeking Process
Recognize and accept
Define problem (address ASK)
Select source
Formulate query (Taylor’s levels: visceral, conscious, formalized, compromised)
Execute query
Examine results
Extract information
Reflect/iterate/stop
2.1. Information-seeking strategies: Analytical and Browse (figure of continua)
2.2. Browsing (see transparencies)

3. Greene et al.  Use pdf version to illustrate examples…visible human; LC; lifelines, etc.
Shneiderman et al.
This addresses analytical search : Four phases
 Formulation, action, review of results, refinement
 The examples meant to demonstrate one step of iterative refinement
4. Overviews and Previews
Use Powerpoint slides on G drive for discussion.  Examples next week
What other views are useful?  What mechanisms may work (e.g., glasses tool)? Any term projects here?

5. One-minute paper
What was the big point you learned in class today?
What is the main, unanswered question you leave class with today?
