5 and you? 5

6 Human-Computer Interaction (HCI) Human the end-user of a program the others in the organization Computer the machine the program runs on Interaction the user tells the computer what they want the computer communicates results 6

7 What is HCI? Task Organizational & Social Issues Design Technology Humans 7

8 User Interfaces Part of software program that allows user to interact with computer user to carry out their task HCI = design, prototyping, evaluation, & implementation of user interfaces (UIs) 8

9 Why Study HCI? Major part of work for real programs approximately 50% [Myers & Rosson 92] Stanford graduates work on real software intended for users other than us Bad UIs cost money (5% ^ satisfaction -> 85% ^ in profits) lives User interfaces are hard to get right 9

10 UI Design Cycle Design Evaluate Prototype 10

11 How to Design and Build UIs User-centered design Task analysis Rapid prototyping Evaluation Programming Iteration 11

12 User-centered Design Know thy User Cognitive abilities perception physical manipulation memory Organizational / job abilities Keep users involved throughout project 12

13 Task Analysis Observe existing work practices Create examples and scenarios of actual use Try-out new ideas before building software 13

14 Rapid Prototyping Build a mock-up of design Low fidelity techniques paper sketches cut, copy, paste video segments Interactive prototyping tools Visual Basic, HyperCard, Director, etc. UI builders & IDEs Eclipse, Visual Studio, 14

15 Evaluation Test with real users (participants) Build models Low-cost techniques expert evaluation walkthroughs 15

16 Iteration At every stage! Design Evaluate Prototype 16

17 Course Syllabus 17

18 Goals of the Course Learn the basics & the latest in HCI cognitive/perceptual constraints design techniques techniques for evaluating a user interface design technology used to prototype & implement UIs Carry out some publishable research 18

19 Lecture Format 11:00-11:25 I ll present the area 11:25-12:15 Student-Led Discussion 19

20 Course Structure HCI literature Conferences papers (chi, uist, cscw, ) journal articles (tochi, hci, ) 3-5 papers/week For student-led discussions ronyeh@cs with list of 3 prefs by Friday Must come prepared cs376@cs with 2 criticisms & 2 good points (w/ reasoning, evidence) 20

21 Grading 50% Projects 25% Paper Critiques 25% Participation & leading in-class discussion 21

22 Projects Research quality projects Meet with Ron and me about proposals 1 page proposals due Thursday, October 7 th Mid-term demo/review Must include an evaluation & iteration Final report 3-4 page paper in chi format (Dec. 12 th ) minute presentation in class (Dec. 13 th ) 22

23 Projects Working in pairs is encouraged A project related to your research (or another course project) is great Let me know if you do this Ron and I are happy to offer project suggestions 23

24 A few thoughts 24

26 Next Time Seminal Ideas As We May Think, Vannevar Bush The Xerox Star: A Retrospective, Jeff Johnson, Teresa L. Roberts, William Verplank, David C. Smith, Charles Irby, Marian Beard, Kevin Mackey User Technology: From Pointing to Pondering, Stuart K. Card and Thomas P. Moran 26

27 Some of this material is based on James Landay s cs260 course at UC Berkeley 27
