HCI Seminar 357

Day 13 Notes

11/30/05

PHR project

1. One-minute papers from the blog:

Open Video design decisions…how to make the tradeoff decisions?

Designing user studies---the complexities and design decisions (art and science)

2.  Online Help. [from last meeting]

The self serve trend:

            Commerce/shopping

            Professional services:  accounting/taxes, banking, health care? (e.g., PHRs)

                        Libraries?  Searching?

                        News? Journalism

            Social services: digital government, e.g., e-rules, voting

Our help framework (from Dominick et al.  Portal Help: http://sils.unc.edu/research/publications/reports/TR-2003-01.pdf

            Tutorials

            FAQs and AnswerGardens

            Reference

            Mediated reference (email, chat, etc.)

            Knowledge-based help systems (context sensitive)

            Animated demonstrations (show mes)

Plaisant & Shneiderman define layered help that is sensitive to system and task context

Haas et al. define interactive glossaries

Help symposium:  Manifesto on help for statistical information http://ils.unc.edu/govstat/helpsymposium.html

3. Pervasive computing:

Ambient rooms (CHI 98 video)  [consider secondary tasks]

            Ambient info solutions best for monitoring/changing data

            Compare to agile views (in focus and the other views)

                        Ways to change view/bring ambient info in focus (our agile mechanisms)

                                    Conscious action

                                    Low engagement in primary task/focus causes attention shift

                                    Anomalous action in the environment invades attention

            Key design issue:  mapping signals (sound, light, etc.) to ambient conditions or tasks

4. Trends in HCI

a. Mobility and Ubiquityà alternative I/O, new work patterns (multi-tasking with a changing environment)

            Ambient/pervasive/location aware computing (e.g., Want & Schilit reading, discussion above)

                        What are the implications for input from the environment rather than user alone?

            Ubiquity, digital libraries as extended memories---back to Engelbart’s augmentation

                        How does ubiquitous information affect design? Consider help, travel, planning

            Calm technology (Weiser reading and his previous work on ubiquity)

                        Cyberinfrastructure is the new environment for design: from physical to virtual

b. Beyond rational designà alternative metrics and design processes?

The role of affect? (e.g., the Norman reading)  the interesting balance/tradeoff between affect and cognition (note the balance of eyes and ears that complement one another; also our findings of tradeoff between efficiency and satisfaction on video retrieval)

Digital jewelry (CHI 01 video)  just for fun?  Functional?

The role of environment and context (ranging from random to constructed worlds)?

Qualitative methods

c. VR and ARà AR as the bridge to VR in ‘deep cyberspace’  AR as the human input (system output) complement to environment as input to systems

5. One-minute paper  (post to blog)

What was the big point you learned in class today?

What is the main, unanswered question you leave class with today?
