Scientific Approach(beyond user friendly) • Specify users and tasks • Predict and measure • time to learn • speed of performance • rate of human errors • human retention over time • Assess subjective satisfaction(Questionnaire for User Interface Satisfaction) • Accommodate individual differences • Consider social, organizational & cultural context
Design Issues • Input devices & strategies • Keyboards, pointing devices, voice • Direct manipulation • Menus, forms, commands • Output devices & formats • Screens, windows, color, sound • Text, tables, graphics • Instructions, messages, help • Collaboration & communities • Manuals, tutorials, training www.awl.com/DTUI hcibib.org useit.com

Leonardo’s Laptop The old computing is about what computers can do, The New Computing is about what people can do mitpress.mit.edu/leonardoslaptop www.cs.umd.edu/hcil/newcomputing
An Inspirational Muse: Leonardo da Vinci (1452-1519) Renaissance Man • Combined science & art • Integrated engineering & esthetics • Balanced technology advances & human values • Merged visionary & practical
Goals for The New Computing 1) Usable: Reliable & comprehensible 2) Universal: Diverse users & varied equipment 3) Useful: In harmony with human needs
1) Usable: Ending User Frustration • Goal: make computer usage less frustrating • Identify top ten frustrations • Measure severity & frequency in lost time • Determine if the situation is improving
1) Time diary study Self reports & observations (111 students) • Pre-session survey: • demographic information • computer experience and attitudes • level of computer anxiety, mood • Users spend 2.5 hours (average) • Report their frustrating experiences • Post-session survey: • assess mood after the session • overall frustration level • loss of time
Internet Applications Operating System timed out/dropped/ refused connections (32) error messages (35) crashes (16) long download time (23) freezes (24) wrong response (10) web page/site not found (17) missing/ hard to find features (23) slow response (8) email (15) crashes (13) unexpected message boxes (6) 1) Frequent Frustrations (out of 373)
1) Minutes lost (111 subjects) – 46% Minutes lost: 7902 Total minutes: 17,453 1196 1230 2081 3395 Web browsing Other minutes lost OS Productive minutes Email
Percent of Internet Use by Educational Attainment 2) Universal: Digital Divide Remains Troubling U.S. Department of Commerce www.ntia.doc.gov/ntiahome/dn/
2) Universal: Diverse Users & Varied Equipment • User diversity: Accommodate users with different skills, knowledge, age, gender, disabilities, disabling conditions (mobility, injury, noise, sunlight), literacy, culture, income, etc. • Technology variety: Support broad range of hardware, software, and network access • Gaps in user knowledge: Bridge the gap between what users know and what they need to know Communications of the ACM, May 2000
2) Universal Usability in Practice www.otal.umd.edu/uupractice/
3) Useful: Generative Theories Beneficial theories: - Descriptive - Explanatory - Predictive - Prescriptive but the big step forward will be - Generative Theories to guide our invention of new technologies
3) Theories of Human Needs • Jefferson: Life, Liberty & the Pursuit of Happiness • Roosevelt: Freedom of speech & expression, religion, from want, from fear • Maslow: Hierarchy of human needs • Physiological • Safety • Love • Esteem • Self-Actualization • Covey: Living, Loving, Learning & Leaving a legacy
Human Needs for Relationships Relationships • Self: working on your own • Family & Friends: 2-50 close intimates • Colleagues & Neighbors:50-5000 acquaintances • Citizens & Markets: 5000 and more
Human Needs for Activities • Activities • Collect: Information • Relate: Communication • Create: Innovation • Donate: Dissemination

Getting to the Golden Age of Usability • Action Items • Developers: Apply usability guidelines & testing methods • Web producers: Develop UU statements • Managers: Provide responsible leadership • Journalists: Raise public expectations • Policy makers: Raise & clarify requirements • Funders: Expand research on usability • Educators: Disseminate scientific results • Researchers: Explore bold new visions
ACM Code of Ethics In a fair society, all individuals would have equal opportunity to participate in, or benefit from, the use of computer resources regardless of race, sex, religion, age, disability, national origin or other such similar factors.
