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

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 Interest in an HCI comp? 18

19 Lecture Format 11:00-11:25 I ll present the area 11:25-11:50 Student presents papers 11:50-12:15 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 55% Projects 15% In-class Lecture 15% Paper Critiques 15% Participation 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 2-4 page paper in chi format minute presentation in class 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 User Interface Design Tools vision, gesture, sensor nets, ubiquitous computing Computational photography Marc Levoy s new cameras: what UIs (both camera and darkroom ) does this imply? explore the iroom 24
