Q

Define the Concept of Feedback in Interaction Design

A

The concept of feedback is that a user should receive feedback after every action they perform to let them know if their action is successful or not.

Q

Define the Concept of Affordance in Interaction Design

A

Affordance is the link between how things look and how they’re used. e. g. When the affordances of a physical object are perceptually obvious, it is easy to know how to interact with it.

Q

Explain perceived and real affordance

A

There is two types of affordance, perceived and real affordance, Physical objects are said to have real affordance whereas User Interfaces that are screen-based are virtual and therefore do not have real affordance (perceived affordance).

Q

What are the benefits of problem space articulation within a team? (3)

A
  1. Bring on different perspectives (e.g. Project Managers, software engineers, etc.)
  2. Less chance of incorrect assumptions and unsupported claims in the final design
  3. Reflection upon ideas in the early stages is very important in helping everyone understand the design

Q

What are the core Problem Space questions asked? (4)

A
  • What are the problems with the existing product or user experience?
  • Why do you think they are problems?
  • How do you think the proposed design ideas might overcome these?
  • if you couldn’t come up with problems:
    How do you think your proposed design ideas support, change, or extend the current ways of doing this?

Q

What are the benefits of conceptualising the design space (Conceptual Model) ? (3)

A
  • Orientation: Enabling the design team to ask specific kinds of questions about how the conceptual model will be understood by the targeted users.
  • Open-Mindedness: Allowing the team to explore a range of different ideas to address the problems identified.
  • Common Ground: Allowing the design team to establish a set of common terms that all can understand and agree upon, reducing the chance of misunderstandings and confusion arising later.

Q

What are the core components of conceptual models? (4)

A
  • Metaphors and analogies
  • The concepts to which people are exposed through the product.
  • The relationships between those concepts.
  • The mappings between the concepts and the user experience.

Q

What are the issues with using metaphors? (6)

A
  • May break conventional and cultural rules
  • Can constrain designers in the way they conceptualise a problem space
  • Forces users to only understand the system in terms of the metaphor
  • Designers can use bad existing designs and transfer the bad parts over
  • Limits designers’ imagination in producing new conceptual models.
  • Might just choose the wrong metaphor.

Compositional Thread
Spatio-temporal thread

32
Q

What is the Sensual thread in UX?

A

Sensory Engagement at a physical level (see, hear, touch, smell, and taste through our sensory organs)

33
Q

What is the Emotional Thread in UX?

A

How do you feel about the product? It refers to value judgments that assign importance to things with respect to our needs and desires

34
Q

What is the Compositional Thread in UX?

A

The way that different elements of experience form a coherent
whole. It refers to “the narrative structure, action possibility, plausibility, consequences and
explanations of actions”

35
Q

What is the Spatio-Temporal Thread in UX?

A

Space and time of the experience and the influence on it.

36
Q

What are the goals of User Experience (UX)? (3)

A
  1. Be Satisfying, aesthetically pleasing, enjoyable, engaging, pleasurable, exciting, supportive of
    creativity
  2. Avoid being frustrating, annoying, unpleasant, patronising, and making one feel stupid.
  3. However
    “I don’t believe there is a set of [User Experience] principles that are applicable in all
    situations”
37
Q

What are personas?

A

They are rich descriptions of typical users of the product under development on which the designers can focus and for which they can design products.

38
Q

What is cognition?

A

It is what goes on in our heads when we carry out our everyday activities

39
Q

What are the core aspects of cognition? (5)

A

Attention: What to concentrate on, what we take in

Perception: How information is acquired from the world and transformed into experiences

Memory: What we can bring back to mind

Reading, speaking, listening: Understanding
words and language

Problem-solving, planning, learning, reasoning,
decision-making…

40
Q

Implications for the interaction design of attention? (6)

A
  1. Help direct the user’s attention
  2. Present (only) the information that is needed right now
  3. Highlight what is most relevant
  4. Use techniques that make things stand out like colour, ordering, spacing, underlining, sequencing and animation
  5. Leave out clutter
  6. Group related information together
41
Q

Implications for the interaction design of perception? (4)

A
  1. Use icons and graphics that are clear and easy to understand
  2. Use borders and spacing to indicate grouping
  3. Spoken words should be clear and audible
  4. Text and background should contrast, clear fonts, large enough, and text legible
42
Q

Implications for the interaction design of memory? (8)

A
  1. Help users quickly recall or recognise
  2. Keep procedures short and simple
  3. Menus and icons are easier than commands
  4. Use common and familiar icons and commands, place consistently
  5. A small number of options
  6. Offer hints to promote memory
  7. Offer different ways for people to organise
    information
  8. Offer search facilities so we don’t have to
    remember where we put things
43
Q

Implications for the interaction design of Language? (2)

A
  1. Only 3 items on a spoken menu
  2. Include options for multiple forms of media
44
Q

Implications for the interaction design of Problem-solving, planning, learning, reasoning, decision-making…? (2)

A
  1. Provide additional (hidden) information/functions for users who wish to understand more about how to carry out an activity more effectively (e.g. web
    searching)
  2. Use simple and memorable functions at the interface for computational aids to support rapid decision-making and planning, e.g. for users on the move.
45
Q

What is a mental model

A

A conceptual framework that’s developed to explain and predict user behaviour based on theories of cognition. Mental model is the user’s perception of how they can do what they want to do.

46
Q

How do we form mental models? (4)

A
  1. Experience
  2. Training
  3. Exploration
  4. Metaphors
47
Q

What do mental models represent?

A

It represents the user’s understanding of how the system works and what it can do

48
Q

How is the mental model related to the conceptual model?

A

The mental model is influenced by the conceptual model

49
Q

How do you create a persona? (4)

A
  1. Capture User characteristics
  2. Synthesise persona from real users
  3. Should be realistic (not perfect people)
  4. Bring them to life with a name, some characteristics not relevant to the product, goal and personal background.
50
Q

How are personas useful? (2)

A
  1. Used to focus design on user needs
  2. Stops getting fixated on general users as many personas may be used to represent users
51
Q

What not to do when creating a persona?

A

Do not be sexist/ ageist / ablest

52
Q

What are user requirements?

A

The User requirements are a set of descriptions of functions that the system being designed should do. It is created after considering who the users are.

53
Q

How can user requirements be represented? (3)

A
  1. Diagrams of how the system will operate/be used
  2. Scenarios or interview transcripts
  3. Mathematically formal descriptions
54
Q

What are the 2 types of User Requirements?

A

Functional Requirements
Non-functional requirements

55
Q

What are functional requirements?

A

What a system can do (NOT how)

56
Q

What are non-functional requirements?

A

Constraints (e.g. running on certain platforms) and Attributes (e.g. appearance, usability…)

57
Q

What are the rules that User Requirements must follow? (5)

A
  1. The following format should be used: The user must/could/should be able to <verb>, The system should/could/must be able to do <verb> for the user</verb></verb>
  2. Be as specific as possible
  3. Should be testable/measurable
  4. Avoid vague wording
  5. They should be complete and consistent
58
Q

What are some methods of gathering User Requirements? (6)

A
  • Interviews
  • Focus groups
  • Participatory design
  • Questionnaires
  • Researching similar products and use for prompting
  • Observing users doing a task
59
Q

What are the 2 main methods for prioritising requirements?

A

4-level system - MoSCoW - Must, Should, Could, Won’t have

3-level System - High, Medium, Low

60
Q

Why should you avoid categorising the importance of requirements using numbers e.g. 1, 2, 3

A

This can cause confusion between which is the most important and least important requirements to include
