ASIST Conference report
RAVE update
Project updates (nov 21 is thanksgiving break, nov 28 trends, dec 5 project presentations)
1. On-minute papers
Adoption practice versus marketing theory/wishes
See-through tools
Doubtful
people can coordinate two-handed inputs
Do
simple, less complicated applications have a better chance of adoption than
complex apps (e.g., table browser vs table lens)?
Can
all the metadata needed to answer all the questions of users be provided?
Why
is statistics a different medium? How
might this impact design?
Will
the Dvorak keyboard (or another non-qwerty example) be adopted?
How
to use see-through tools? (think about suites, styles and metaphors rather than
single widgets)
2. Mechanisms: Pad++ and Jazz
Bederson & Hollan
Jazz available for download http://www.cs.umd.edu/hcil/jazz/
An alterative to scroll and jump
The metaphor discussion (pros and cons of metaphors) and moving beyond existing media to a ‘physics of information appearance and behavior’
What are the natural applications for zooming?
What are the limits?
Show the progression of Pad-Pad++-Jazz work

Broader discussion
We have been considering representations and mechanisms all semester. It seems obvious that we want to have a designer kit that has different reps and different mechanisms and a challenge of design is how to map reps to tasks/problems and then map these reps to appropriate mechanisms. It seems obvious that these mappings must be used in concert, as sets (e.g., metaphors for the entire interface or an interaction style rather than a hodge-podge of cool techniques). These mappings are constrained by technical environments (e.g., WWW and Java libraries), but more importantly by user expectations, and the installed base of styles. Imagine we want to identify a small set of actions people want to take on information resources. What goes on the list?
