Human-Computer Interaction (HCI)
Humanthe end-user of a programthe others in the organization
Computerthe machine the program runs on
Interactionthe user tells the computer what they wantthe computer communicates results

What is HCI?
HumansTechnology
Task
Design
Organizational &Social Issues
27 September 2005 8cs376 Introduction
User Interfaces
Part of software program that allowsuser to interact with computeruser to carry out their task
HCI = design, prototyping, evaluation, & implementation of
user interfaces (UIs)
27 September 2005 9cs376 Introduction
Major part of work for “real” programsapproximately 50% [Myers & Rosson ‘92]
Stanford graduates work on “real” softwareintended for users other than “us”
Bad UIs costmoney (5% ^ satisfaction -> 85% ^ in profits)lives
User interfaces are hard to get right
Why Study HCI?
27 September 2005 10cs376 Introduction
UI Design Cycle

27 September 2005 11cs376 Introduction
How to Design and Build UIs
User-centered designTask analysisRapid prototypingEvaluationProgrammingIteration
27 September 2005 12cs376 Introduction
User-centered Design
“Know thy User”Cognitive abilities
perceptionphysical manipulationmemory
Organizational / job abilities Keep users involved throughout project
27 September 2005 13cs376 Introduction
Task Analysis
Observe existing work practicesCreate examples and scenarios ofactual useTry-out new ideas before building software
27 September 2005 14cs376 Introduction
Rapid Prototyping
Build a mock-up of designLow fidelity techniques
paper sketchescut, copy, pastevideo segments
Interactive prototyping toolsVisual Basic, HyperCard, Director, etc.
UI builders & IDEsEclipse, Visual Studio, …
27 September 2005 15cs376 Introduction
Evaluation
Test with real users (participants)Build modelsLow-cost techniques
expert evaluationwalkthroughs
27 September 2005 16cs376 Introduction
IterationAt every stage!

Goals of the Course
Learn the basics & the latest in HCIcognitive/perceptual constraintsdesign techniques techniques for evaluating a user interface designtechnology used to prototype & implement UIs
Carry out some publishable research
