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

4
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

Information Visualization
  • The eye
  • the window of the soul,
  • is the principal means
  • by which the central sense
  • can most completely and
  • abundantly appreciate
  • the infinite works of nature.

An Inspirational Muse Leonardo da Vinci
(1452-1519)
  • Renaissance Man
  • Combined science art
  • Integrated engineering esthetics
  • Balanced technology advances human
    values
  • Merged visionary practical

22
Goals for The New Computing
  • 1) Usable Reliable comprehensible
  • 2) Universal Diverse users varied
    equipment
  • 3) Useful In harmony with
    human needs

23
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

24
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

25
1) Frequent Frustrations (out of 373)

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

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
31
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

    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

44
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,
