13. Human Computer Interaction (HCI)
HCI - process of two-way communicating between human and computer.
Interface - media for information and action between human and computer.
HCI consists of Human side and Computer side.
Step of interaction process:
Information is represented by computers.
Information is perceived by human.
Information is interpreted by human.
Decision is made by human.
Information is represented by human.
Information is stored by computers.

14. UX - conception
Try to explain, how You understand the term “user experience”
Use other HCI terms to support Your arguments:
usability
user
interface
time
interaction design
•
•
•
•
•
What is it? (e.g: user is a person, usability is products property)
15. UX - conception
General idea
Experience emerges from the intertwined works of
perception, action, motivation, emotion and cognition in
dialogue with the world (place, time, people, and objects).
User Experience (UX) is not much different from experience per
se. It simply focuses interest on interactive products.
Emotion is main aspect in UX!
16. UX - conception
Experience in interaction - User experience
UX requires both interactive product and user to be present.
•
•
•
•
•
Blue circle is UX
Green circle is usability
Overlapping area of both circles
is UX-pragmatics.
Non overlapping area of blue
circle is UX-hedonics.
Non overlapping area of green
circle is accessibility
17. UX - conception
Connected aspects
•
•
•
•
User Engagement (UE) - part of interaction process. which
keeps users going on with interaction.
Affordances - object’s feature to provide a way to complete
an action. Affordances may not be connected to intended
task.
Learnability - products ability to provide skills. Good
learnability means that skills come quicker.
Trust - users attitude to product. trust is higher when user is
not worried about own’s security.
18. UX - not only user and computer
from perspective of usage process UX is influenced by:
Interface is located between
(interactive) content and user.
Interaction quality depends on
context.
Context can be for example:
● user profile
● users mental state
● device (computer) settings
19. Time factor
Short time experience:
•
First impression.
Long time experience:
•
•
Episode of use - several minutes
Longitudinal use - several days
Repeated use:
•
.
Same as longitudinal but time is counted not as
minutes, days but how many times product has been used
20. UX - Users perspective
Pragmatic aspects:
Perceiving information
Interpreting information
Decision making
•
•
•
Hedonic aspects:
Emotions
Satisfaction
Pleasure
•
•
•
21. UX - Designers perspective
Pragmatic aspects:
Providing information
Storing information
Information architecture
•
•
•
Hedonic aspects:
Creativity
Aesthetics
Expressivity
•
•
•
22. UX - conception
Try to revise, Your previous explanation of term “user
experience”
Bring in more terms to rely on while explaining:
•
•
•
•
•
usability
user
interface
time
interaction design
What is it? (e.g: user is a person, usability is products property)
24. First we need to Understand…
The Facts of life
2014
Sónia Sousa & Mati Mottus
23
25. Essential characteristics
• The fact is that…
– Interactive media is changing society
• One should ask,
– how do we establish
• what impact these changes has on our usage
experience
• This phenomena that can be observed
– from 2 views
• The environmental thesis
• The anti-deterministic view
2014
Sónia Sousa & Mati Mottus
24
26. Two views
• The environmental thesis
– For McLuhan (1967) we are metaphorically fish
that are unaware of the mediating water that
surrounds us
• The anti-deterministic view
– For Williams (1974) it is human agency and the
activities of societies and cultures that affect the
nature of technology, not the other way around
2014
Sónia Sousa & Mati Mottus
25
27. Question?
So… do we drive or are we driven by
the development of interactive
media?
2014
Sónia Sousa & Mati Mottus
26
29. knowledge domain
• Human-computer interaction
– Dedicated to understand
• how people interact with computer; or
– To understand If computer are developed for
provide
• successful interaction with humans
2014
Sónia Sousa & Mati Mottus
28
30. Related knowledge domain
• Interaction design
– A design discipline dedicated to defining the
behavior of artifacts, environments and systems
• User experience design
– established to cover the holistic perspective to
how a person feels about using a system
– The focus is on pleasure and value rather than on
performance
2014
Sónia Sousa & Mati Mottus
29
32. Implications
This implies to be
able to measure the quality of the
interactive products.
2014
Sónia Sousa & Mati Mottus
31
33. How to measure
• In the beginning HCI community started to focus
on
– Quality measures like measuring
• user performance (effectiveness);
• task-oriented settings measures (Efficiency).
– But, with the new generation of interactive products
(mobile, ubiquitous, social)
– that is not enough as…
• This do not explains user satisfaction
• Product attractiveness
• The (emotion) aspects and qualities of the product
2014
Sónia Sousa & Mati Mottus
32
34. Question?
• Does recent advances in
mobile, ubiquitous, social
– Pushed human-computer interaction into more
practically all areas of human activity
• IF SO..
– This has led to a shift away from the usual stress
on usability to a much richer scope of user
eXperience, where
2014
• user's feelings, motivations, and values are given as
much, if not more, attention than
efficiency, effectiveness and basic subjective
satisfaction
Sónia Sousa & Mati Mottus
33
35. What is then…
User eXperience evaluation and how
it fits in User eXperience scope
2014
Sónia Sousa & Mati Mottus
34
37. User experience
• According to the standard ISO 9241-210, user
experience is the…
– Person’s perceptions and responses that result
from the use or anticipated use of a
product, system or service
2014
Sónia Sousa & Mati Mottus
36
38. User experience
• According to Roto, Law, Vermeeren &
Hoonhout (2011), user experience is the…
– An active and passive encounter with a system
• Dynamic and changing over time, it includes, according
to these authors, usability and interface design
2014
Sónia Sousa & Mati Mottus
37
39. User experience
• According to Hanssenzahl and Tractinsky
(2006), user experience is…
– A consequence of the characteristics of the
system, the user’s internal state and the context
2014
38
40. User experience
• Kuniavsky (2003) describes user experience
as…
– Building on information design, interaction
design, and identity design
2014
Sónia Sousa & Mati Mottus
39
41. User experience
• Further, to Jetter and Gerken (2010), user
experience is…
– A wholesome result of design and marketing
values
2014
Sónia Sousa & Mati Mottus
40
42. User experience
• And finally, according to Nielsen, Norman and
Tognazzini (2011), user experience is even
more comprehensive as it…
– Encompasses all aspects of the end-user’s
interaction with the company, its services, and its
products
2014
Sónia Sousa & Mati Mottus
41
43. Agreement points
• Some common UX concept points
1. UX emerges from user’s interactions;
2. Is dynamic and can change over time;
3. Requires a multidisciplinary approach
• graphical design, interaction design, marketing, economy
• But it aims to,
– Create meaningful experience to the user by looking
at
• What a person feels when using it?
• Observing how useful, easy of use and efficiency is the
product
2014
Sónia Sousa & Mati Mottus
42
44. Useful models
• On top of providing good illustrations of
distinct conceptualizations of what user
experience is all about
– This model provide a useful lens to evaluate user
experience and should be selected according to
the purpose in mind
2014
Sónia Sousa & Mati Mottus

out of the five UX sources provided in the course
