Talk Overview


Talk Overview• What is a seminar?• The complete computer

scientist• The textbook

What is a seminar?


Hatology• CSC385 @KU – many hats

Capstone course Senior design course Comprehensive Exam Professional preparation

Workforce Graduate studies


SeminarA small group of advanced students engaged in intensive study and/or research


Seminar• Features

In depth discussions Advanced topics Everyone participates Interact with practical problems Wrestle with theoretical issues Ongoing Socratic dialogue


Socratic Dialogue• Form of inquiry and debate

between individuals with opposing viewpoints based on asking and answering questions to stimulate critical thinking and to illuminate ideas.


Socratic Dialogue• Inquiry• Debate • Opposing viewpoints • Asking questions• Stimulate critical thinking• Illuminate ideas


The Complete Computer Scientist


The Complete Computer Scientist• Every professional

strives to be complete/consummate in her profession.


Complete• Synonyms

faultless, full, integrated, thorough, thoroughgoing, undiminished, whole

• Antonymsdeficient, lacking, missing,

wanting


Consummate• Synonyms

able, accomplished, complete, finished, perfected, skilled, thoroughgoing, trained, whole

• Antonyms incomplete, unfinished


The Complete Computer Scientist• Must . .

be a student of the human mind become a consummate designer understand the synergistic

relationship between artist and instrument

Textbook – Goals & Topics


Textbook Goals• Engender Socratic dialogue• Introduce advanced topics• Discuss practical problems• Guide senior design project


Textbook Goals• Introduce professionalism• Introduce practical research• Discuss key principles• Wrestle with current issues


Textbook Topics• Under development• Constrained by

What I know Am studying

• Seeking dialogue and input


Textbook Topics – as of now• Engelbart Synergy Principle

• Design• Ethics• Advanced computational issues• The CS profession• {More to come}

Always welcome input from colleagues


Design• Design theory• Design process• Design practice


Ethics• Foundations of ethics• Information ethics

Subsumes computer ethics• Business ethics

Intellectual property Patent law Anti-trust


Computational Issues• Tractability

Basics “Accidental” vs. essential

• Computability Theory Practice

• Commensurability


The CS Profession• CS as academic discipline

19th and 20th century roots Astride two extremes

Abstract Practical {Frank Zappa Principle}

Turing Award & recipients


The CS Profession• CS as profession

Professional responsibilities Codes of professional ethics Professional organizations Professional development

The iNewton Principle


Engelbart Synergy Principle


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.


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.


Engelbart’s Proposal• Comprehension

more rapid better in situations previously too complex

• Solutions• speedier• better• to problems before insoluble.


Engelbart’s Proposal• Including professional problems of . .

diplomats executives social scientists life scientists physical scientists attorneys designers


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.


Demo that changed the world• December 9, 1968

• Fall Joint Computer Conference• Introduced

computer mouse video conferencing teleconferencing hypertext


Demo that changed the world• Introduced

word processing hypermedia object addressing and dynamic

file linking bootstrapping collaborative real-time editor


Demo that changed the world• Engelbart with geographically

distributed team demonstrated the NLS ("oN Line System") to the 1,000 computer professionals in attendance.

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

– Andries van Dam {Brown University}


Designing for

Interactivity


Design Theory• The key:: Synergistic Interactivity• Crucial concepts

Interaction design Embodied cognition Mental model Mental model space Affordances & constraints


Designing for Interactivity


Mental Model Space• Art/architecture design metrics

symmetry balance unity simplicity Also

contrast, depth, harmony, interest, rhythm, sequence, variation, theme


Mental Model Space• Fractionated mental model space

unaesthetic discomfiting perplexing disruptive

• Examples cntrl-z (delete) & cntrl-x (save) brake & gas pedals


Milieu-Oriented Design


Milieu-oriented Design• V3 Principle

VeniVidiVici

• I came, I saw, I conquered


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


Vidi• Observation that is:

DeliberateFocusedSelective

• Identify critical factors within milieu of use


Vidi• Sherlock Holmes to Dr. Watson:You see,

but you do not observe.The distinction is clear.


Vidi• Mott’s observation at Ginn:

Text editor itself was intuitivePeople stumbled over

filingprintingdeleting


Vidi• Verplank’s 5 mouse tests

Distilled essence of mouse operation

Abstract tests to capture essenceI.e., deliberate, focused,

selective observation


Vidi• Observation has revealed

Necessary featuresUnderlying problems Inherent constraints


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}


Vici• Forge the solution

Engelbart: Seek augmenting human

intellect

spectrum of interactive

technology


Embodied Cognition


Embodied Cognition• An emerging understanding• Cognitive processes are deeply

rooted in the body’s interactions with the world. Psychology Philosophy Cognitive science A.I.


Embodied Cognition• Experimental evidence:

Body’s interactions with world affect cognitive processes

heavy media multitaskers perform worse on tests of task-switching ability requiring concentration


Embodied Cognition• Anecdotal evidence:

Joe Theisman: Mike McCarthy’s goal is to get Aaron Rogers into a rhythm early in the game


Embodied Cognition• Anecdotal evidence:

Technostress: undesirable effects of improperly implemented technology in the workplace. Many examples run counter to the

natural rhythms of the worker. E.g., the “always on syndrome”

♦ expectation to be continually connected and respond to workplace issues during what would normally be considered family time


Milieu-oriented Design• Understanding of embodied

cognition extends realm of design Beyond purview of software

engineer To system administrator Management Workers’ advocate (e.g., union)


Conclusion• Many more topics to cover

• To formulate:Organizing principlesUnifying themes


Conclusion• Questions to ask

E.g., what is a computer?

• Ideas• Suggestions• Criticisms

all welcomed
