Models

Question 1

What is theory?

Answer 1

• Means to analyse and predict performance.
• Explanation of phenomenon
• Can help identify factors (eg cognitive, social etc..)

Question 2

What is a model?

Answer 2

A simplification of an HCI phenomenon.

Makes it easier for designers to predict and evaluate alternative designs.

Question 3

What is a framework?

Answer 3

Set of interrelated concepts and/or specific questions for ‘what to look for’.

Provide advice on how to design.

Question 4

What is general process when designing user interfaces?

Answer 4

Start with 0 designs, make lots of designs and then refine them until you have 1.

Question 5

Give a model of the design process

Answer 5

Analysis:

• Requirements gathering, market research
• Design brief

Iteration:

• Design
• Prototyping
• Evaluation/critique

Implementation

Question 6

What should all designs being with?

Answer 6

Should know who the end users are.

User communities can be expected to carry with them usage patterns and certain knowledge

Question 7

What is a persona?

Answer 7

Prototypical user often created by synthesising data from surveys or interviews.

Question 8

What are the advantages of personas?

Answer 8

Put a human face to an abstract customer.

Help team members share a consistent understanding of end-users

Benefits of solutions and features can be understood by directly relating them to personas.

Question 9

What are the 8 steps of rapid contextual design?

Answer 9

1. Contextual enquiry
2. Interpretation sessions and work modelling
3. Model consolidation and affinity diagram building
4. Persona development
5. Visioning
6. Storyboarding
7. User environment design
   8: Interviews and evaluations with paper prototypes and mock-ups

Question 10

What is contextual inquiry?

Answer 10

Conduct field studies to observe and understand tasks being performed

Question 11

What is interpretation and work modelling?

Answer 11

Team discussions draw conclusion from step 1.

Workflow processes, work culture and work policies are understood as to how they impact end-user’s tasks.

Question 12

What does model consolidation and affinity diagram building do?

Answer 12

Present understanding of data so far to targeted population of end-users

Identify work patterns and processes and arrange these concepts into affinity diagrams.

Question 13

What is visioning?

Answer 13

Review data and personas

Define how the system will aid the end-users with their tasks

Capture key ideas and express vision of revised workflow for end-users

Question 14

What is the process of storyboarding?

Answer 14

Use vision to guide detailed redesign of user tasks.

Defines and illustrates the assumptions behind the new implementation.

Question 15

What is user environment design?

Answer 15

Express a single coherent representation of users and works that is to be performed.

Question 16

What happens during the interviews and evaluations with paper prototypes & mock-ups?

Answer 16

Carry out interviews and tests with end-users, move around the prototyping space.

Ensure the new system meets end-user requirements

Question 17

What is participatory design?

Answer 17

Direct involvement of people in the collaborative design of the things and technologies they use.

End-users commit to repeated meetings with specific role

Question 18

What are the arguments in favour of participatory design?

Answer 18

More user involvements bring more accurate information about tasks.

End-users have an opportunity to influence design decisions

Question 19

What are the arguments against participatory design?

Answer 19

Extensive user involvement is lengthy and thus costly

Antagonism from end-users not involved in participatory design

Designers may compromise their design

Question 20

What is mass-participatory design?

Answer 20

Users and potential users self-select
