tonight?3. What (computer-based) POS systems do you typically
encounter as a customer in a standard week?4. What process would you use to find the latitude and
longitude of the statue of Gregor Mendel on the plaza in front of the Mendel Science Center?

Goals Developing design principles Investigating models and theories Creating evaluation processes
– Experimentation– Opinion
Outlining an effective design process—interface engineering
Proposing interface designs

Themes (1) Hierarchy of design principles Models Theories (or theory) Awareness
– Mental models– Common interactions– Microsoft vs. Apple vs. others– General knowledge

Strategies (Ways of Knowing) Create concept maps for reading
assignments– Combine individual maps
Slip-of-paper (SOP) questions and surveys– Summarize results
Lectures, sometimes Discussion, always Argumentation, when appropriate

Hot Areas; Burning IssuesThe List
Errors made through inadvertent gestures, e.g. iPad, Wii Bad default choices; not checking device properties, e.g.
zoom setting Discrepancies between presentation and function, e.g. bad
choice of icons Error cost of wrongly pressed, chosen widgets. Non-intuitive interfaces to systems, e.g. synching iPod and
iTunes System time-outs Discoverability of functionality, especially advanced
features Foreshadowing completion of tasks

iPad A new small device Issues of design and user interaction?
– Discoverability of functionality– Easy to learn elementary functionality– Lack of multitasking, only single window– Keyboard design– Accidental gesture interpretation– Inconsistent interfaces across apps
(extends to all software)
![Page 28: User System Interface CSC 8570-001](https://reader035.vdocuments.site/reader035/viewer/2022081507/5681694e550346895de0eb76/html5/thumbnails/28.jpg)
iPad(5)– Displaying non-mobile web sites– Pinch zoom– Scroll to end?– Is it trying to be a computer?
![Page 29: User System Interface CSC 8570-001](https://reader035.vdocuments.site/reader035/viewer/2022081507/5681694e550346895de0eb76/html5/thumbnails/29.jpg)
What to Study: Potential Topics Tiny interfaces: Cell phones, smartphones, PDAs,
ultramobile PCs, house systems, POS systems Gesture-based input; pen interfaces Intelligent interfaces (cf. IUI) Task analysis (e.g. buying a ticket) Collaboration tools/systems (cf. CSCW) Personalization; recommender systems Friendly forms Creating digital libraries Mashup tools Web-based interfaces to systems, to information, for
task completion

Reading a Research Paper Expect to find
– Abstract– Introduction– Description of experiment– Discussion of results– Conclusion – Proposals for future work– References
![Page 31: User System Interface CSC 8570-001](https://reader035.vdocuments.site/reader035/viewer/2022081507/5681694e550346895de0eb76/html5/thumbnails/31.jpg)
Reading (2) Try the abstract—though it may be too
abstract, too condensed. Read the introduction until you get
confused. Read the conclusion. Look at the reference list—hoping to find
papers you already know about. Check the headings and first few lines of
the middle sections for ease of understanding.

Reading (3) Examples:
– Mackenzie: Unipad text entry– Soukoreff and Mackenzie
: Metrics for text entry errors

Next Time Read Wigdor & Balakrishnan, Tilt Text:
using tilt for text input to mobile phones. (You can get a copy of the paper from the ACM Digital Library.)
Evaluate its structure and content as a research paper.
Identify design principles for user interfaces based on the paper.
Hand in your solution to the table exercise.

Next Time (2) Install EndNote on your computer
and record the references from the Wigdor paper in it.– EndNote has been available for loan
from the library. Check with the Reference Desk
Install the CMAP software on your computer and capture the principal ideas of today’s lecture in it.

Next Time (3) What is the difference between
taxonomy and ontology? How is the field of HCI divided?
