HCI Seminar 357
Day 8 Notes
One minute summaries
Main Point
Interface server components
already exist
Usability is more science
than art
Usability studies are
designed, and thus subject to design decisions
No ultimate usability metrics
Potential for interface
server to relieve some UI expense from data providers
Usability
metrics include efficiency, functionality, errors and user
satisfaction.
Question
Is satisfaction the most
important u criterion?
What is a good usability
study (qualities, criteria, etc.)
What is the interface
boundary? How to separate the
application and data?
How to control satisfaction
questionnaires (bias, context)?
Next steps in usability r&d?
Why are see through tools not
used?
Is there a (principled) way
to determine how much data to cache in RB+ (e.g., in each thread?)
Differences
between web interface and application interface?
Is interface server more
about data integration or user friendliness?
Have we reached a design
plateau?
1. Usability and HCI
research. Beyond usability to
understanding user behavior and HII
2. Eye tracking as a
technique
for user input
to track behavior and infer
cognition
Guest discussion: Anthony Hughes with demo in IDL
3. biometrics
for input/control
controlling robot arms by thought: Nicolelis work
Guest
discussion: Jimmy Ivory on bioback
Biometrics readings:
What is my identity? What are my extensions? Where do I begin and end (parents, children,
DNA)? What agents represent me? Are
these hyperlinks? My
citations? Exoinformation leaking from me? What can I effect? Spatially? Temporally?
4. Assignment: Outline a study design that incorporates
physiological data (due next week)
