Agenda
Reading Review Lecture Lab Team/Project
Kathy E. Gill, uwdigitalmedia.org
Recap: Our goal is flow
The process of an optimal experience The activity feels seamless It is intrinsically enjoyable Individual loses self-consciousness
Kathy E. Gill, uwdigitalmedia.org
Five Tests of Effectiveness (1/2)
Time to learn How long does it take for typical members of the community to learn how to complete task?
Speed of performance How long does it take to perform relevant benchmarks?
Rate of errors by users How many and what kinds of errors are commonly made during typical applications?
Kathy E. Gill, uwdigitalmedia.org
Five Tests of Effectiveness (2/2)
Retention over time Frequency of use and ease of learning help make for better user retention
Subjective satisfaction Allow for user feedback – interviews (focus groups), online surveys (both free-form comments and satisfaction scales).
Kathy E. Gill, uwdigitalmedia.org
Design for Diversity
Personality differences Cultural and international diversity Users with disabilities Elderly users Anything else?
Kathy E. Gill, uwdigitalmedia.org
Raskin’s Rules
The user should set the pace of the interaction
Error avoidance, facilitated with “undo/redo”
Accessible to the naïve, efficient for the expert
Kathy E. Gill, uwdigitalmedia.org
Errors are not mistakes!
Mistakes are the result of conscious deliberation
Slips result from automatic behaviorNorman’s Types: capture, description, data-
driven, associative activation, loss-of-activation and mode errors
Kathy E. Gill, uwdigitalmedia.org
Good Error Messages
Polite Illuminating Treat the user with respect
Kathy E. Gill, uwdigitalmedia.org
Design for Error
Minimize occurrence by understanding the causes of errors
Make detection and recovery easier Change the attitude toward error from
“stupid user” to “stupid design”
Kathy E. Gill, uwdigitalmedia.org
One small problem:
When you design an error-tolerant system, people come to rely on that system (it had best be reliable!)Anti-lock brakes (ABS)Blade guard on circular sawAnything else?
Kathy E. Gill, uwdigitalmedia.org
To increase errors, add a little:
Social pressure Time pressure Economic pressure
In other words, real life!
Kathy E. Gill, uwdigitalmedia.org
Resultant design philosophy:
Put knowledge in the world (iow, make options visible)
Remember the three questions:Where am I, where can I go, where have I
been? Design for errors
Kathy E. Gill, uwdigitalmedia.org
Sitemaps (1/2)
Organizing content – the backbone of your information architecture
It is human tendency to organize things to make them easier to retrieve
Kathy E. Gill, uwdigitalmedia.org
Sitemaps (2/2)
How to learn how people think about your contentObserveVisit competitor web sitesEvaluate server logsCard sorts
Kathy E. Gill, uwdigitalmedia.org
Card sort (1/3)
List of information by topic Cards (or post-it notes for affinity
diagram) Group Name the group
Kathy E. Gill, uwdigitalmedia.org
Card sort (2/3)
Look for patterns – dominant organization scheme
Adjust for consistency ID categories that don’t match
May be featuresMay just be oddball
Test the resulting patterns
Kathy E. Gill, uwdigitalmedia.org
Card sort (3/3)
Category refinement = taxonomy Examples:
