  2. Today • Finish Project Team Formation • View Xerox Star video • Start User Centered Design

  3. User Interface TimeLine • Apple Macintosh • ’84-’86 • http://www.digibarn.com/collections/screenshots/Apple%20Macintosh%20v1-1%20-%201984/ • Apple 2gs • ’86-’92 • http://fp3.antelecom.net/gcifu/applemuseum/iigs.html • Mac II • Circa ’87-90 • http://fp3.antelecom.net/gcifu/applemuseum/mac2.html • Windows 3.0 • Released ’90 • http://en.wikipedia.org/wiki/Image:Windows_3.11_workspace.png • Windows 95 • Released ’95 • http://en.wikipedia.org/wiki/Windows_95 • Xerox Alto • Circa ’73 • http://www.digibarn.com/collections/systems/xerox-alto/ • Xerox Star • Circa ‘81 • http://members.fortunecity.com/pcmuseum/alto.html • Unofficial Apple timeline: • http://fp3.antelecom.net/gcifu/applemuseum/index.html • Apple Lisa: • Lisa 1 and 2, circa ’83-’85 • http://en.wikipedia.org/wiki/Apple_Lisa#Software • http://fp3.antelecom.net/gcifu/applemuseum/lisa2.html • http://www.digibarn.com/collections/screenshots/Apple%20Lisa/

  4. Why User-Centered Design? • System will fail if it: • does not do what the user needs • is not appropriate for the user • Why don’t we just define a “good interface”? • There is a huge variety of users and tasks • Guidelines are usually too vague e.g. “Provide feedback”, “Be intuitive” Slide by James Landay

  5. User-Centered Design Overview • Needs assessment • Find out • who users are • what their goals are • what tasks they need to perform • Task Analysis • Characterize what steps users need to take • Create scenarios of actual use • Decide which users and tasks to support • Design based on this • Evaluation • Test interface by “walking through” tasks • Do this before implementation

  6. Participatory Design • A subset of user-centered design • User actively participates in design of the system • Pros: • potentially more accurate information about the tasks • more opportunity for users to influence the design decisions • buy-in from sense of participation • potential greater acceptance of final system Slide adapted from Ben Shneiderman

  7. Participatory Design • Cons (potential): • more costly • lengthier implementation period • antagonism from those whose suggestion are not incorporated • force designers to compromise design • exacerbate personality conflicts between designers and users • highlight organizational politics Slide adapted from Ben Shneiderman

  8. Example: Student Course Enrollment:How to Help Students Achieve their Goals? achieve lifetime of success become successful IT manager learn to build useful systems enroll in i213

  9. Help Users Achieve Goals • Example: Course Enrollment Software • What matters from the programmers’ point of view? • What matters from users’ point of view? • What about the course administrators?

  10. Next Week • Project Proposal Due • Readings: • Cooper (Inmates, Chs. 9-11) • Holtzblatt (in reader) • Newman & Landay • Topics: • Tuesday: Personas • Thursday: Resume user-centered design
