Study Notes
Interaction Design Relationship
- Interaction design (ID) is related to Human-Computer Interaction (HCI), Ubiquitous Computing, Human Factors, Cognitive Engineering, Cognitive Ergonomics, and Computer Supported Co-operative Work.
- ID combines academic disciplines such as psychology, social sciences, computing sciences, engineering, ergonomics, and informatics.
- ID combines design practices such as graphic design, product design, artist-design, industrial design, and film industry.
The User Experience
- The user experience is how a product behaves and is used by people in the real world.
- Core characteristics of interaction design:
- Users should be involved throughout the development of the project.
- Specific usability and user experience goals should be identified, clearly documented, and agreed to at the beginning of the project.
- Iteration is needed through the core activities.
Accessibility and Inclusiveness
- Accessibility: the extent to which an interactive product is accessible by as many people as possible.
- Inclusiveness: making products and services that accommodate the widest possible number of people.
Usability Goals
- Effective to use
- Efficient to use
- Safe to use
- Have good utility
- Easy to learn
- Easy to remember how to use
User Experience Goals
- Desirable aspects:
- Satisfying
- Helpful
- Fun
- Enjoyable
- Motivating
- Provocative
- Engaging
- Challenging
- Surprising
- Pleasurable
- Enhancing sociability
- Rewarding
- Exciting
- Supporting creativity
- Emotionally fulfilling
- Entertaining

- Frustrating
- Patronizing
- Making one feel guilty
- Making one feel stupid
- Annoying
- Cutesy
- Childish
- Gimmicky
Design Principles
- Generalizable abstractions for thinking about different aspects of design
- The do's and don'ts of interaction design
- Derived from a mix of theory-based knowledge, experience, and commonsense
Feedback and Constraints
- Feedback: sending information back to the user about what has been done, including sound, highlighting, animation, and combinations of these.
- Constraints: restricting the possible actions that can be performed, helping to prevent user from selecting incorrect options.
- Physical objects can be designed to constrain things.
Consistency
- Design interfaces to have similar operations and use similar elements for similar tasks.
