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.

UX - conceptionTry 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)

UX - conceptionGeneral 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!

UX - conceptionExperience 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

UX - conceptionConnected 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.

UX - not only user and computerfrom 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

Time factorShort 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

.

UX - Users perspective

Pragmatic aspects:

• Perceiving information

• Interpreting information

• Decision making

Hedonic aspects:

• Emotions

• Satisfaction

• Pleasure

UX - Designers perspective

Pragmatic aspects:

• Providing information

• Storing information

• Information architecture

Hedonic aspects:

• Creativity

• Aesthetics

• Expressivity

UX - conceptionTry 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)

Summary

User experience in contextconcepts and terminology


First we need to Understand…

The Facts of life

2014


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


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


Question?

So… do we drive or are we driven by the development of interactive

media?

2014


Let’s observe this

In context

2014


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


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



Implications

This implies to beable to measure the quality of the

interactive products.

2014


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


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 • user's feelings, motivations, and values are given as

much, if not more, attention than efficiency, effectiveness and basic subjective satisfaction2014


What is then…

User eXperience evaluation and how it fits in User eXperience scope

2014


Different definition

User eXperience

2014

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

Sónia Sousa & Mati Mottus2014

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


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

40

User experience

• Kuniavsky (2003) describes user experience as…– Building on information design, interaction design,

and identity design


41

User experience

• Further, to Jetter and Gerken (2010), user experience is…– A wholesome result of design and marketing

values


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



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

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



First reading assignment

• Step 1 : Read and understand it concept terminology out of the five UX sources provided in the course lectures thoroughly.

• Step 2 : Select one article or one chapter of the UX sources provided in dropbox.

• Task: Write a one page review, reflecting on the chapter or article’s main contributions and arguments... please try to summarize your thoughts in one page.
