Lecture 2-Interaction design Flashcards
What is interaction design?
Designing interactive products to support the way people communicate and interact in their everyday and working lives. –> how a product behaves
Who is involved in interaction design(2)?
-Need understanding of users, technology, business,…
-Multidisciplinary teams(engineers, designers, product managers)
What is the benefit of interaction design?
More creative and original designs
What are the 2 disadvantages of interaction design(2)?
-Different languages and values –> problems in communication
-Complex and costly
What are the core characteristics of interaction design(3)?
-Users should be involved throughout the development of the project.
-Specific usability and user experience goals need to identified, documented and agreed to at START of project.
-Iteration is needed through the core activities.
What are the 5 design principles for interaction design?
Visibility :
-we can “see” how to do use a device
Feedback:
-Sending information back to the user about what has been done.
Constraints:
-Restricting the possible actions that can be performed to prevent the user from selecting incorrect options.
Consistency:
-Designing interfaces to have similar operations and use similar elements for achieving similar task →usable and learnable
What is user experience(UX)?
It focuses on the overall experience between a user and a product.How a product behaves and is used by people in the real world.
- Cannot design a user experience-only can design FOR a user experience
What is user interface(UI)?
It’s the process of making interfaces in software or computerized devices with a focus or style.
What is Information Architecture(IA)?
It’s a structural design of shared information environments, the art and science of organizing and labelling websites, online communities and software to support usability and fundability.
What is IxD?
It examines the interaction(via an interface) between a system and its user.
What is the definition of accessibility?
The extent to which an interactive product is accessible by as many people as possible.
What is the definition of inclusiveness?
Making products and services that accommodate the widest possible number of people.
What are the types of disabilities(3)?
1.Sensory impairments
2.Physical impairments
3.Cognitive impairments
What are the 3 categories of impairment?
Permanent
Temporary
Situational
What are the 6 usability goals? (SULEME)
1.Effectiveness
2.Efficiency
3.Safety
4.Utility
5.Learnability
6.Memorability
What is efficiency?
The way a system supports users in carrying out their tasks.
Criteria: time to complete a task, # of operations to complete a task
What is safety?
Protecting the user from dangerous conditions and undesirable situations.
Criteria: # of errors, time to recover from errors
What is utility?
The extent to which the system provides the right kind of functionality so that users can do what they need or want to do.
Criteria: availability of core tasks
What is learnability?
How easy a system is to learn to use
Criteria: time to learn a task, errors made in learning a task
What is memorability?
How easy a system is to remember how to use, once learned.
Criteria: errors made in carrying out a task after system is learned
