3. 1. short history of HCI research visionaries Vannevar Bush, 1945, As we may think Doug Engelbart, 1962, Augmenting human intellect: a conceptual framework

4. 1. short history of HCI research user participation Enid Mumford: ETHICS (~1980) Scandinavian approach

5. 1. short history of HCI research user-centered design Modeling the user interface Pfaff (Seeheim model, 1985) Moran (CLG, 1981); Tauber (UVM, 1988) a systematic process Modeling task knowledge Johnson & Johnson (TKS) Paterno (CCT)

6. 1. short history of HCI research contextual design Beyer & Holtzblatt (1997) "Contextual Design: a Customer-Centered Approach to Systems Designs"

7. "User Centered Design" coming of age! Norman & Draper (1986) User Centered System Design: New Perspectives on Human-Computer Interaction Vredenburg et al. (2000) User-centered design: An Integrated Approach Garrett (2002) The Elements of User Experience: User-Centered Design for the Web Lambropoulos & Zaphiris, 2006) User-centered Design of Online Learning Communities

8. HCI conferences 25 year anniversary ECCE (Europ. Conf.in Cogn. Engineering ) 1982 CHI (Human factors in computing systems) 1982 Interact 1984 so we seem to have succeeded...... “My students do not need to talk to people” (professor in computer science, Amsterdam, 2006) Ergonomics

9. 2. old and new misconceptions 2.1. the user can do it Dutch Open University service desk, dispatcher statistics 2005, frequency of call categories "reset password"

10. 2. old and new misconceptions 2.2. if only the system is user friendly

11. 2. old and new misconceptions 2.3. all users want the same thing: International bank case: management / head office bank shops

12. 3. the "H" in HCI - whom am I designing for? different users and stakeholders have different goals

13. the users: 2005: 6,000,000 new registrations: 100,000/month often played in geographically spread groups

14. the client

15. 3. the "H" in HCI - whom am I designing for? different users and stakeholders have different goal goals may change / develop only in an actual context

16. new client goals: training for “teamwork, integrity and leadership”

17. 3. the "H" in HCI - whom am I designing for? different users and stakeholders have different goals goals may develop only in an actual situation the client of design is not always willing to support all user goals should the designer consider all stakeholders? Taliban / Sunnite / Shiite groups

18. 3. the "H" in HCI - whom am I designing for? different users and stakeholders have different goals goals may develop only in an actual situation the client of design is not always willing to support all user goals "the user" suggests too simple a design space!

19. 4. HCI in 2007 and beyond developing technology (Moore's law); changing types of applications ("intelligent", "connected", "embedded"); broadening scope of presence in society and environment; changing unit of analysis (activity); changing focus (functionality → experience) moving interest in / from scientific disciplines (psychology, arts). the context of use is a partner now

20. 4. HCI in 2007 and beyond developing technology (Moore's law); changing types of applications ("intelligent", "connected", "embedded"); broadening scope of presence in society and environment; 4.1. changing unit of analysis (activity); 4.2. changing focus (functionality → experience) 4.3. moving interest in / from scientific disciplines (psychology, arts). 4.4. the context of use is a partner now

21. 4.1. a new paradigm: activity centered design human (user's) goal priority is function of situation: individual history (do I know customer at my desk?); the culture experienced as actual (do I consider myself employee of bank X, or team member of branch Y?); the context (my branch manager aims at keeping a client friendly image); actual needs (how to get rid of the cue at my desk).

22. activity centered design situated goals → situated activities (Norman, 2006: "human-centered design considered harmful") activities will be chosen by people based on situated goal priorities (e.g., in a meeting, phone rings) activities may be delegated to other agents if these can take the related role, depending on the context this asks for a change in task analysis → activity analysis

23. 4. HCI in 2007 and beyond developing technology (Moore's law); changing types of applications ("intelligent", "connected", "embedded"); broadening scope of presence in society and environment; 4.1. changing unit of analysis (activity); 4.2. changing focus (functionality → experience) 4.3. moving interest in / from scientific disciplines (psychology, arts). 4.4. the context of use is a partner now

24. 4.2. Experience – what is it anyhow? a “buzz word” “living” the interaction with artifacts in fact nothing new, and still includes functionality and usability

25. a changed in HCI culture from... experts – developing their own tools “no user interface please” to... reactive and intelligent environment for everybody – part of the situation, culture, and organization “I do not care what's inside, if it serves my purpose”: useful (for my purpose) usable (fit to my understanding, possibilities and context) safe (acceptable risk) motivating (convincing / fun / warning / unpredictable)

26. which experience should HCI be aiming at? e.g. Designing a web site = designing a specific experience for the web intended by the client & experienced by the user challenge for HCI research: how to build scientific knowledge to support methods and techniques.

27. example from a web design company- "generic experiences": Shopping Learning Feeling part of a community Finding Information Playing Being entertained Creating stuff Personal enrichment … Often a mix of a primary experience with others

28. model for shopping: attract Inform activate

29. Attracting customers Form: credibility quality of execution Content: personal interest Sensational content Specialized content

30. Nike (Attract)

31. Informing customers …drawing people into the online messages Provide understanding rather than plain information Help the audience to: Recall Comprehend Evaluate

32. Nike (Inform)

33. Invoke customer action Persuading people to ‘buy’ the online message and take action Present insight Provide guidance Elicit performance Provide reinforcement / feedback / reward

34. Nike (Invoke – take action)

35. arts and crafts in HCI research: needs a systematic HCI research approach the whole process needs a scientific base: from requirements to presentation and documentation knowledge is available in practice find inspiration and quests from real clients and use in context

36. 4. HCI in 2007 and beyond developing technology (Moore's law); changing types of applications ("intelligent", "connected", "embedded"); broadening scope of presence in society and environment; 4.1. changing unit of analysis (activity); 4.2. changing focus (functionality → experience) 4.3. moving interest in / from scientific disciplines (psychology, arts). 4.4. the context of use is a partner now

37. 4.3. new solutions require new HCI disciplines Computer science & Psychology & Ergonomics  Ethnography, Anthropology, Sociology  Theater, Graphic design, Cinematography, Industrial design, Multimedia design  HCI, formal specifications, tools, patterns CSCW, Contextual design, design of collaboration and organization poor academics need to go to creative and consider experience design: arts and crafts

38. 4. HCI in 2007 and beyond developing technology (Moore's law); changing types of applications ("intelligent", "connected", "embedded"); broadening scope of presence in society and environment; 4.1. changing unit of analysis (activity); 4.2. changing focus (functionality → experience) 4.3. moving interest in / from scientific disciplines (psychology, arts). 4.4. the context of use is a partner now

39. government funding of research projects in several countries now ask for industrial commitment: small & medium sized enterprises, as well as government and health care bodies are (non funded) partners for academic projects "industrial" experts as part time academic researchers (paid by industry) "industrial" review boards

40. be aware: industrial practice was there before academia Apple Advanced Technologies Xerox PARC IBM Science Centers Philips Design Microsoft international banks Nokia

41. different flavors of "new" HCI seem to emerge in academia in Communication Science in Industrial Design - not much research in Artistic Design (multimedia, games) - no theory? specialization in Computer Science – often a hard time and a decreasing number of students Psychology? - seems to have lost interest!

42. 5. summary and conclusion recognized systematic HCI approaches emerged, based on theory, models, and research but misconceptions never disappeared and "old" knowledge is no longer true the "H" is no longer the optimal unit of analysis, so change the unit of analysis (activity in context) broaden the focus (functionality → experience) identify basic disciplines (psychology → arts) partner with the "context"
