Syllabus and links to class notes available at:

Main Points
Human interaction difficult/impossible? To automate
HCI is not a brand new field
IT tools lead to improved productivity and different decision making processes
IT tools have potential to augment but long way to go
Questions
Buckets dependent on search engines, how must SE’s change to optimize?
Are there reviews/syntheses of HCI (Yes…many ;-)
How to predict whether/why specific technogies (e.g., smart cards) accepted in a community?
More on closure in user-system interactions?
Can bucket-queen communication be self-organizing?
Is there a downside of augmentation, e.g., dependence?
Is access to all the info enough? Better to get right info at right moment?
What is bootstrapping?
Is there an algorithm/equation for intellect enhancement?
Sequential vs parallel processing in IR?
2. Reading discussions
Discuss Marchionini 1992.
10 years old—are the assumptions valid today?
1. people are task oriented
2. people are resource smart/lazy
3. info growth unlimited, software & interfaces greatest opps
Information seeking functions (process in 1995)
Recognize/accept; define problem, select source, form query/action, execute query/action, examine results, extract info, reflect/stop
Trends/Issues---still valid today?
1. extend to multimedia (DLs)
2. improve problem definition and info extraction
3. work on collaborative interfaces
4. beyond string search in IR
5. new I/O devices
6.
intelligent
interfaces (e.g., agents, user profiles)
7. diversity and individual diffs
Discuss Greene et al
The role of surrogates
Overviews: surrogates for a collection
Previews: surrogates for an object
Representations & Mechanisms
Guidelines
Use salient surrogates
Use multiple surrogates
Use multiple levels of surrogates
Use surrogates for size, extent, availability
Leverage data types
Choose metaphors that map onto primary task or data
Sequence surrogates, capitalize on natural orderings
Provide direct manipulation control mechanisms
Discuss Shneiderman et al.
Formulation (discuss Liddy’s NLQ grammar for our table project)
Action
Review Results
Refinement
3. Discuss Agileviews as current thinking (Powerpoint slides on G drive)
