Question 10

“Design is not just what it looks like and feels like. Design is how it works.”

Steve Jobs

Question 11

describes the practice as: “the goal of creating products that enable
the user to achieve their objective(s) in the best way possible.”

The Interaction Design Foundation

Question 12

makes a product useful. A product is bought to be used. It has to satisfy certain criteria, not
only functional, but also psychological and aesthetic.

Answer 12

Good design

Question 13

is one which is not easy to understand, distracting, difficult to use and short lived

Answer 13

Bad design

Question 14

He develop the ten principles of good design

Answer 14

Dieter Rams

Question 15

10 Principles of design

*Good design is innovative.
*Good design makes a product useful.
*Good design is aesthetic.
*Good design makes a product understandable.
*Good design is unobtrusive.
*Good design is honest.
*Good design is long-lasting.
*Good design is thorough down to the last detail.
*Good design is environmentally-friendly
*Good design is as little design as possible

Question 16

involves the study, planning, and design of the interaction between
people (users) and computers.

Answer 16

Human Computer Interaction

Question 17

Interaction Design is the practice of:

Answer 17

 understanding users’ needs and goals
 designing tools for users to achieve those goals

Question 18

What is the difference between interaction design and HCI?

Answer 18

According to the definition in Interaction Design — Beyond HCI, IxD is
much broader than HCI, because it includes all means of technology,
system, and products, while HCI concerns interactive computing
system.

Question 19

In designing interactive products the following questions should be considered:

Answer 19

who are going to use it?
how its going to be used? And;
where its gonna be used?

Question 20

refers to how a product behaves and is used by people in the real world.

Answer 20

The user experience

Question 21

Important aspects of the user experience are the following

Answer 21

usability
functionality
aesthetics
content
look and feel
emotional appeal

Question 22

Two Components of Human Memory

Answer 22

1. working memory
2. long-term memory.

Question 23

where you do your
conscious thinking.

Answer 23

Working memory

Question 24

is probably the least
understood part of human cognition.

Answer 24

Long-term memory

Question 25

is an
essential principle
probably the most
important in
communicating a
model to the user.

Answer 25

Visibility

Question 26

The various types of user interfaces include:

Answer 26

graphical user interface (GUI)
command line interface (CLI)
menu-driven user interface

Question 27

Golden rule of design:

Answer 27

understand your materials

Question 28

is an
important Windows security
feature.

Answer 28

User Account Control

Question 29

– Use linked labels to provide secondary navigation that shows
the path from the front to the current site page in the hierarchy.

Answer 29

Breadcrumbs

Question 30

Forms can put users off registration. So, use this sign-up pattern to
let
users sample what your site/app offers for free or familiarize
themselves with it

Answer 30

Lazy Registration

Question 31

Let users enter data in various formats (e.g., city/town/village or zip
code)

Answer 31

Forgiving Format

Question 32

Make buttons stand out with color so users know what to do

Answer 32

Clear Primary Action

Question 33

Show users only features relevant for the task at hand, one per screen.
If you break input demands into sections, you’ll reduce cognitive load
(e.g., “Show More”)

Answer 33

Progressive Disclosure

Question 34

Hide nonessential information on detailed pages to let users
find
relevant information more easily.

Answer 34

Hover Controls

Question 35

designers typically combine this with a wizard pattern

Answer 35

Steps Left

Question 36

Dark patterns are risky because user mistrust and feedback can
destroy a brand’s reputation overnight.

Answer 36

Dark Patterns

Question 37

about creating interventions in often complex situations using technology of many
kinds including PC software, the web and physical devices.

Answer 37

Interaction design

Question 38

Design involves:

Answer 38

– achieving goals within constraints and
trade-off
– understanding the raw materials:
computer and human
– accepting limitations of humans and of design

Question 39

Here are some more examples of commonly-seen affordances in
graphical user interfaces. B

Answer 39

Downward-pointing arrows
Texture
Mouse cursor
Visible highlighting
Make Commands Visible

Question 40

A. understand computers

Answer 40

– limitations, capacities, tools, platforms

Question 40

B. understand people

Answer 40

– psychological, social aspects, human error

Question 41

Users need to find their way around a system. This involves:

Answer 41

– helping users know where they are, where they have been and what they can do next
– creating overall structures that are easy to understand and fit the users’ needs
– designing comprehensible screens and control panels

Question 41

Complexity of design means we don’t get it right first time:

Answer 41

– so we need iteration and prototypes to try out and evaluate
– but iteration can get trapped in local maxima, designs that have no simple improvements, but are not
good
– theory and models can help give good start points.
