SE 204, IES 506 – Human Computer Interaction Lecture 7: Evaluating Interface Designs Lecturer: GazihanAlankuş Please look at the end of the presentation for assignments (marked with TODO)
Outline • Weekly show and tell about interfaces that you use • Talking about your experience with the homework • Continuing evaluating designs
Show and Tell • What good/bad interfaces have you seen lately?
Nokia smartphones • I helped my uncle yesterday. It took me more than an hour… • Hard to tell which internet connection you are using. Wifivs GSM data. • Menus under menus under menus… Many keys that you use in the process…
Your experience with the homework • People who didn’t observe a user were going to observe • How many people did? • How many still need to do? • High school students? • Let’s hear from your experience • How did it go? • What were the difficulties? • Have you learned anything? • What would you change next time?
What have we done so far? • Identify a problem • Identify requirements • Create a prototype • Evaluate the prototype • Evaluate yourself • Evaluate with experts • Evaluate through user tests
User Tests • Find users! • Test prototypes with them
Recruiting Users • Find people with the same experience level as the typical user • Don’t get people who are familiar with the product or your views on it. • Be careful about “friends and family” testing • Public places like libraries, dining halls, coffee shops can be good places to find people who wouldn’t mind helping for a few minutes. • Some companies have user testing labs that they set up and they handle recruiting users. • In academia, we often post fliers or set up agreements with local organizations. • A small budget to give out gift certificates or something can help.

How should you conduct user tests? • Some Techniques for Observing Users • Kathleen Gomoll, Advanced Technology Group, Apple Computer, Inc. • Please read! • Qualitative Evaluation Techniques • Saul Greenberg • We will follow his slides today
TODO:Homework week 6 due next Thursday (April 2) • If you haven’t used a campus visitor BEFORE creating a paper prototype you have to do this: • Create another prototype, with actual ethnographic observation • Remember our iterative loop! • Bring a guest to IEU! • Observe what they want to find/do/see • Interview them • (optionally) participatory design • Form hypotheses based on your observations, make the prototype(s) accordingly • You can use high school students. Talk to BarışBey in ÖğrenciDekanlığı
TODO:Homework week 7 due April 16 • Get two users to test your prototype • Don’t have to be on campus (can be if you want) • Should be in your target audience (people that do not know the IEU campus well) • Identify a couple of clear tasks that your interface is created to address • Test each of them one by one • Videotape the prototype • Optionally, also videotape the user’s face • Learn from the user test • Follow the instructions in Saul Greenberg’s slides • Create the necessary deliverables
TODO: Homework for IES 506 only, due two weeks from now • Rettig, M (1994) Prototyping for tiny fingers. Communications of the ACM, April, Vol.37,No.4. • Summarize it in about a page • Also • Send me weekly reports about your projects • Previous summaries were due today
TODO: Prepare for the midterm • Mark your calendars for the midterm exam • 9 April • 17:30-19:20 • Location: C302, C303
