CS 3724 Introduction to Human Computer Interaction Section 2 CRN 11500 MW 2: 30 -3: 45 126 Mc. B

Where Are We? About 1/4 through the Semester q Scenario-Based Design q Read Chapters 1 -5 q Lectures/exercises on: q q q q Team Building Users, (Front-End) Requirements Analysis, and Ethnography What is Design? Where Do Ideas Come From? Representations Formative Evaluations Information Visualization

Are We Meeting the Goals of Course ? q OFFICIAL VERSION Survey of concepts, theory, and practice. Interdisciplinary underpinnings. Evaluation of computer-based technology. User-oriented perspective: human (cognitive, social) and technological (i/o, interactions styles, devices). q Design guidelines, evaluation methods, participatory design, communication between users and system developers. q q q STEVE HARRISON’S VERSION q q Learn that HCI topic is both wide and deep. Design involves asking good questions Convince some of you that HCI is phat / cool Convince the rest of you that HCI expertise is needed in most computer projects

Today’s Agenda q CS 3724 so far q Kinds of HCI Design q q UE: Activity, Information, and Interaction Experience, Narrative, and Genre User-Centered Speculative q Methods q q Metaphor Periscope Role-playing Design Review

Some Kinds of Design q Activity q Information q Interaction q Experience q Narrative q Genre q User-centered q Speculative • UE: • Highest level of abstraction • Functionality • Activity Design Scenarios • Methods: • Wizard of Oz • Metaphor • Persicope

Some Kinds of Design q Activity q Information q Interaction q Experience q Narrative q Genre q User-centered q Speculative • UE: – – • Middle level of abstraction Information theory Presentation Info Visualization Methods: – Graphic design – Cog. Psych lab experiments – Sketches of screens

Some Kinds of Design q Activity q Information q Interaction q Experience q Narrative q Genre q User-centered q Speculative • UE: – Lowest level of abstraction – I/O – ergonomics • Methods: – Mental models – Performance optimization (e. g. Fitt’s Law) – Cog. Psych lab experiments

Some Kinds of Design q Activity q Information q Interaction q Experience q Narrative q Genre q User-centered q Speculative • Not In UE • Used in: – Theme park rides – Immersive games • Gestalt – “look and feel” – Crosses all UE Levels • Methods: – storyboard

Some Kinds of Design q Activity q Information q Interaction q Experience q Narrative q Genre q User-centered q Speculative • Not In UE • Used in: – Games – Interactive fiction • Literary/cinematic – Crosses all UE Levels – Scenarios users live in • Methods: – Role-playing

Some Kinds of Design q Activity q Information q Interaction q Experience q Narrative q Genre q User-centered q Speculative • Not In UE • Used in: – New media – Exhibit design • How is meaning communicated? – Crosses all UE Levels – What genres are possible? • Methods: – Deconstruction – Persicope – Recombinant construction

Some Kinds of Design q Activity q Information q Interaction q Experience q Narrative q Genre q User-centered q Speculative • Not In UE • Used in: – Most HCI • Think like a user – Crosses all UE Levels – Like SBD, but develops standards no scenarios • Methods: – GOMS – Storyboards – Participatory

Some Kinds of Design q Activity q Information q Interaction q Experience q Narrative q Genre q User-centered q Speculative • Not In UE • Used in: – Quickly done products • Come up with something unlike anything else – Crosses all UE Levels • Methods: – Analogies from totally unrelated areas

Graphic Design q. Cog. Psych Lab Experiments q. Mental Models q. Performance Optimization q. Role-playing q. Deconstruction q. Recombinant Construction q. GOMS q. Storyboards q. Participatory q.

Methods we’ll learn this week: q. Brainstorming q. Delphi planning method q. Hierarchical task analysis q. Morphological Box q. Wizard of Oz q. Metaphor q. Persicope q. Graphic Design q. Cog. Psych Lab Experiments q. Mental Models q. Performance Optimization q. Role-playing q. Deconstruction q. Recombinant Construction q. GOMS q. Storyboards q. Participatory q. Analogies From Totally Unrelated Areas q. Concept Selection q. Design Review

Role Playing q. Very much like Wizard of Oz q. Ideation / validation q. Method: q. Start with scenario q. Act out interaction q. Improvise q. Use props

Metaphor q. Ideation q. Method: q. Generate (I. e. brainstorm) analogs q. Re-describe activity in scenario using metaphor q. Develop representations based on metaphor q. Do not confuse metaphor with what is being represented!

Periscope q. Ideation / Validation q. Can be used with morphological box and/or brainstorming q. Method: q. Come up with “good” ideas q. Figure out what category they are in q. Then figure out other ideas in same category (space) q. Are they also “good” ideas?

Design Review q. Validation, Analysis, Teaming q. Like “claims” in SBD q. The compliment to brainstorming q. Form of reflection q. Method: q. Give alternative courses of action q. Golden Rule: focus on idea q. Articulate the position you coming from (that is, are you speaking as an expert, pretending to be the user, someone with a particular model of how the system works, etc. )
