27. Engelbart Synergy Principle PACISE 2012

28. Engelbart Synergy Principle • Augmenting human intellect: a conceptual framework {1962} • Augmentation Research Center • Stanford Research Institute (SRI) • Contrast - #’s, DP, evolution • Proximate influence • Xerox PARC • Apple Computer, Inc. PACISE 2012

29. Engelbart’s Proposal • By augmenting human intellect we mean increasing the capability of man to approach complex problem situations, to gain comprehension to suit his particular needs and to derive solutions to problems. PACISE 2012

30. Engelbart’s Proposal • Comprehension • more rapid • better • in situations previously too complex • Solutions • speedier • better • to problems before insoluble. PACISE 2012

31. Engelbart’s Proposal • Including professional problems of . . • diplomats • executives • social scientists • life scientists • physical scientists • attorneys • designers PACISE 2012

32. Engelbart’s Proposal • We do not speak of isolated clever tricks that help in particular situations. • We refer to way of life in an integrated domain. PACISE 2012

33. Demo that changed the world • December 9, 1968 • Fall Joint Computer Conference • Introduced • computer mouse • video conferencing • teleconferencing • hypertext PACISE 2012

34. Demo that changed the world • Introduced • word processing • hypermedia • object addressing and dynamic file linking • bootstrapping • collaborative real-time editor PACISE 2012

35. Demo that changed the world • Engelbart with geographically distributed team demonstrated the NLS ("oN Line System") to the 1,000 computer professionals in attendance. • http://faculty.kutztown.edu/rieksts/385/days/01jan26.html • http://www.dougengelbart.org/firsts/dougs-1968-demo.html PACISE 2012

36. Demo that changed the world • Doug gets credit for persisting in spite of the fact that 90% of the people thought he was a crackpot – Bill Paxton {team member} • His vision hasn't really been realized in today's environment – Andriesvan Dam {Brown University} PACISE 2012

37. Designing for Interactivity PACISE 2012

42. Milieu-Oriented Design PACISE 2012

43. Milieu-oriented Design • V3 Principle • Veni • Vidi • Vici • I came, I saw, I conquered PACISE 2012

44. Veni • Designer goes to where product will be used • Deep immersion in the deployment environment • Mott & Tesler go to Ginn Publishing • Participatory design • Guided fantasy PACISE 2012

45. Vidi • Observation that is: • Deliberate • Focused • Selective • Identify critical factors within milieu of use PACISE 2012

46. Vidi • Sherlock Holmes to Dr. Watson: • You see, • but you do not observe. • The distinction is clear. PACISE 2012

47. Vidi • Mott’s observation at Ginn: • Text editor itself was intuitive • People stumbled over • filing • printing • deleting PACISE 2012

48. Vidi • Verplank’s 5 mouse tests • Distilled essence of mouse operation • Abstract tests to capture essence • I.e., deliberate, focused, selective observation PACISE 2012

49. Vidi • Observation has revealed • Necessary features • Underlying problems • Inherent constraints PACISE 2012

50. Vici • Forge the solution • Mott @ Ginn: • Seek to allow • move documents around same way as editor allows to move text around the document. _ Office Schematic {desktop metaphor} PACISE 2012
