Lesson 3

Question 1

Is the process of developing a tool from the perspective of how it will be understood and used by a human user.

An iterative design process in which designers focus on the users and their needs in each phase of the design process.

Answer 1

User-centered Design (UCD)

Question 2

To a system design results in a product that delivers more efficiently, satisfyingly, and user-friendly experience for the user; thus, leading to increased sales and customer loyalty.

Answer 2

Employing UCD

Question 3

PRINCIPLES OF UCD

Answer 3

2) Maintain consistency
3) Use simple and natural dialogue
5) Provide adequate feedback
7) Let the user take charge
9) Offer Assistance
10. Error-free

1) Design for the users and their tasks
4) Reduce unnecessary mental effort by the user
6) Provide adequate navigation mechanisms
8) Present information clearly

Question 4

THE PROCESS OF UCD

Answer 4

• Specify the context of use
• Specify requirements
• Create design solutions
• Evaluate designs

Question 5

Identify the people who will use the product, what they will use it for, and under what conditions they will use it.

Answer 5

Specify the context of use

Question 6

Identify any business requirements or user goals that must be met for the product to be successful.

Answer 6

Specify requirements

Question 7

This part of the process may be done in stages, building from a rough concept to a complete design.

Answer 7

Create design solutions

Question 8

Evaluation - ideally through usability testing with actual users - is as integral as quality testing is to good software development.

Answer 8

Evaluate designs

Question 9

_ 10 general principles for interaction design. They are called “_” because they are broad rules of thumb and not specific usability guidelines.

Answer 9

Jakob Nielsen’s
heuristics

Question 10

10 Usability Heuristics for User Interface Design

Answer 10

1) Visibility of system status
2) Match between system and the real world
3) User control and freedom
4) Consistency and standards
5) Error prevention
6) Recognition rather than recall
7) Flexibility and efficiency of use
8) Aesthetic and minimalist design
9) Help users recognize, diagnose, and recover from errors
10) Help and documentation

Question 11

The first principle is about keeping users informed about their actions and what’s happening at a given interaction.

Answer 11

1) Visibility of system status

Question 12

This principle claims that a system should always speak the user’s language and follow real-world conventions.

Answer 12

2) Match between system and the real world

Question 13

A good UI design should never impose an action on the user or make decisions for them. Instead, the system should only suggest which paths the users can take.

Answer 13

3) User control and freedom

Question 14

This heuristic is about keeping the same language throughout the system to avoid confusing the user.

Answer 14

4) Consistency and standards

Question 15

This Nielsen heuristic proposes that a good design should always prevent problems from occurring.

Answer 15

5) Error prevention

Question 16

As seen, Nielsen’s heuristics aim to reduce users’ cognitive load, and this also includes their memory capacity.

Answer 16

6) Recognition rather than recall

Question 17

Your designs should benefit both inexperienced and experienced users.

Answer 17

7) Flexibility and efficiency of use

Question 18

As a designer, please don’t consider aesthetics above functionalities.

Answer 18

8) Aesthetic and minimalist design

Question 19

Your designs should help the user identify and find solutions to eventual problems and errors.

Answer 19

9) Help users recognize, diagnose, and recover from errors

Question 20

The last of Nielsen’s heuristics concerns documentation that will help users understand how to perform their tasks.

Answer 20

10) Help and documentation

Question 21

Don Norman’s Principles of Interaction Design

Answer 21

Visibility
Feedback
Constraints
Mapping
Consistency
Affordance

Question 22

Is the basic principle that the more visible an element is, the more likely users will know about them and how to use them.

Answer 22

Visibility

Question 23

Is the principle of making it clear to the user what action has been taken and what has been accomplished. Many forms of _ exist in interaction design, including visual, tactile, audio, and more.

Answer 23

Feedback

Question 24

Is about limiting the range of interaction possibilities for the user to simplify the interface and guide the user to the appropriate next action. This is a case where _ are clarifying, since they make it clear what can be done.

Answer 24

Constraints

Question 25

Is about having a clear relationship between controls and the effect they have on the world. You want this _ to feel as natural as possible.

Answer 25

Mapping

Question 26

Refers to having similar operations and similar elements for achieving similar tasks. By leveraging _ elements throughout your entire experience, you make your experience far easier to use.

Answer 26

Consistency

Question 27

Refers to an attribute of an object that allows people to know how to use it. Essentially to afford means to give a clue. The physical button on a mouse gives a clue that it can be clicked to perform an action. When an object has strong _, it’s very clear how to use it.

Answer 27

Affordance
