  • UX conception and terms IFI7155 http://ifi7155.wordpress.com/ Sonia Sousa Mati Mõttus Tallinn University Institute of Informatics 2014
  • 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 - 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)
  • 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!
  • 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
  • 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.
  • 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
  • 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
  • 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 - 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)
  • Summary User experience in context concepts and terminology
  • First we need to Understand… The Facts of life 2014 Sónia Sousa & Mati Mottus 23
  • 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
  • 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
  • Question? So… do we drive or are we driven by the development of interactive media? 2014 Sónia Sousa & Mati Mottus 26
  • Let’s observe this In context 2014 Sónia Sousa & Mati Mottus 27
  • 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
  • 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
  • 2014 Sónia Sousa & Mati Mottus 30
  • Implications This implies to be able to measure the quality of the interactive products. 2014 Sónia Sousa & Mati Mottus 31
  • 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
  • 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
  • What is then… User eXperience evaluation and how it fits in User eXperience scope 2014 Sónia Sousa & Mati Mottus 34
  • Different definition User eXperience 2014 Sónia Sousa & Mati Mottus 35
  • 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
  • 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
  • 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
  • User experience • Kuniavsky (2003) describes user experience as… – Building on information design, interaction design, and identity design 2014 Sónia Sousa & Mati Mottus 39
  • 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
  • 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
  • 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
  • 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 43
  • 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. • Please see the course blog for more information – Remember this is a independent work assignment. – The deadline is 13.February 2014 Sónia Sousa & Mati Mottus 44
