  • The course is titled F27ID Introduction to Interactive Design.
  • Reviewing examples of good and bad designs is part of the overview.
  • Evaluating design to prevent problems is also discussed.
  • The presentation clarifies usability vs. user experience.
  • A discussion about the topic is planned.

Usability in Interaction Design

  • The importance of usability and interaction design is questioned.
  • Issues arising from design failure are explored.
  • Preventing design failure by ensuring good usability is highlighted.
  • The user-centered design process, introduced in Lecture 1, is emphasized.
  • Interaction design is considered pervasive.
  • Examples of interaction design in everyday objects are encouraged.

Norman Doors

  • The concept of "Norman Doors" (a term coined by Don Norman) exemplifies poor design choices.
  • The presentation shows images of doors with inconsistent push/pull mechanisms.
  • Poor design in interactions leads to frustrating and inconvenient experiences.

Interaction Design Communication

  • Effective design communicates interaction, eliminating the need for extra labels.
  • Intuitive design is crucial.
  • The design should convey the intended interaction without needing additional instructions.

Usability in Interaction Design Consequences

  • Bad design can have serious implications beyond mere inconvenience.
  • Preventable errors in hospitals, exceeding diabetes and traffic accidents in severity, are cited as examples of the dangers of bad design.
  • The presentation includes images of medical devices (perfusion pumps).

Levels of Response to a Product - Don Norman

  • Different levels of user response to products were described.
  • (Visceral, Behavioral, Reflective).

User Experience (UX)

  • Usability (Effectiveness, Efficiency, Learnability, Error Prevention, Memorability) is a core part of a good user experience.
  • A positive user experience is desirable

UX Threads

  • Sensual thread: How the product feels physically (sights, sounds, touch).
  • Emotional thread: How the product affects the user emotionally (satisfaction, frustration).
  • Compositional thread: How the different elements of the product create a cohesive experience.
  • Spatio-temporal thread: How the product or system is experienced over time and across space.

Interaction Design Goals

  • Develop usable products.
  • Evaluate whether the product does what it's intended to do.
  • Assess whether interacting with the product is simple and effective.
  • The product must deliver a positive user experience.

User Experience Goals

  • How the success of UX is determined.
  • Evaluating User experience is difficult due to the subjective nature of experience.
  • Understanding user feelings, behaviors and motivations is vital for creating good UX.
  • More information is available in the F28ED(Y2) and F20AD(Y4) modules.

Usability vs UX

  • Usability and UX are linked but not equivalent.
  • Good usable design often leads to a positive user experience.
  • The importance of usability and user experience varies by application.
