live usability lab: see one, do one & take one home
DESCRIPTION
Presentation for the Connecticut State Library / Continuing Education, September 11, 2008. This innovative half-day workshop will provide background on usability and define the user experience (UX). We will offer a "live usability lab" with audience assessment of one library web site and provide time and resources to create usability scenarios for YOUR web resources. Attendees will participate in interactive usability testing to evaluate web-based library resources from the user's perspective. You will also develop questions and methodology to assess usability and the UX @ your library!TRANSCRIPT

Paul Marty:
“… only a small amount of time is necessary to demonstrate … that the best way to evaluate an interface for usability is to test that interface with representative users.”

Why Should We Care About UX?
“Your web site is the embodiment of your library ... For customers to feel they have a good relationship with your library, they must first feel they have a good relationship with the web site — and that begins with the user experience.”
Paraphrased from Garrett, J.J. “Customer Loyalty and the Elements of User Experience”
The Elements of User Experience
What is Usability?
Usability … assesses how easy user interfaces are to use. The word “usability” also refers to
methods for improving ease-of-use during the design process.
Jakob Nielsen, Usability 101
Components of Good Design
•Learnability•Efficiency•Memorability•Error recovery•Satisfaction
Satisfaction?
Shneiderman, “Designing for Fun”
Satisfaction –> Fun
Shneiderman, “Designing for Fun”
How to Achieve Good Design
• Think like a user
• Consistent design
• Tweak text
Thinking Like a User
“… let’s acknowledge the vital importance of empathy for the user. Only by understanding and caring about the perspective of the individual can we design useful, usable solutions.”

Reading Online is Like ??
Reading Proust – Read long sentences online because it’s
easy to keep your place, follow complex trains of thought, and flip to the next screen of dense text
orSkimming citations
– Skim titles & abstracts for keywords, take notes, and move to the next citation
Reading Online: ProustFor a long time I used to go to bed early. Sometimes, when I had put out my candle, my eyes would close so quickly that I had not even time to say "I'm going to sleep." And half an hour later the thought that it was time to go to sleep would awaken me; I would try to put away the book which, I imagined, was still in my hands, and to blow out the light; I had been thinking all the time, while I was asleep, of what I had just been reading, but my thoughts had run into a channel of their own, until I myself seemed actually to have become the subject of my book: a church, a quartet, the rivalry between Francois I and Charles V. This impression would persist for some moments after I was awake; it did not disturb my mind, but it lay like scales upon my eyes and prevented them from registering the fact that the candle was no longer burning. Then it would begin to seem unintelligible, as the thoughts of a former existence must be to a reincarnate spirit; the subject of my book would separate itself from me, leaving me free to choose whether I would form part of it or no; and at the same time my sight would return and I would be astonished to find myself in a state of darkness, pleasant and restful enough for the eyes, and even more, perhaps, for my mind, to which it appeared incomprehensible, without a cause, a matter dark indeed.
Swann’s Way / Marcel Proust

Jargon to Library Users
• “ERIC, I think it’s some kind of journal … some kind of citation.”
• Reference Shelf “[It’s] very general. You don’t know what to expect as it could be anything.”
Jargon for Librarians
• On travelocity, you need the cheapest round-trip ticket from Boston to London.
• These are your options – which is right?
1) Flights & Prices2) Fares3) 3 Best Itineraries
Usability Testing
• Define users• Design questions to mimic what users
would realistically do• Do usability testing early & often
– 3-5 users highlights 85% of errors– Better to test several small groups than 10-
15 at once
• Note errors, redesign and retest

How We Will Test
Volunteers Required
• Anyone who hasn’t used iCONN?• Willing to answer questions about iCONN
in front of the rest of us?!• Leave the room for ~5 minutes• I will
– Demonstrate iCONN– Describe the usability test questions
@ iCONN
• Union Catalog (reQuest)• Licensed, proprietary – reliable! –
databases • Authentication, access• Federated searching
• http://www.iconn.org/
Read to the “Tester”
Usability Test Questions
• Login to iCONN site• Find the book 7th Heaven by James
Patterson. Does your library own it? If your library doesn’t own the book, how would you get it?
• Find a recent article on global warming. • Find a table of contents for Consumer
Reports. • Choose a resource that lets you search
your family history.

Redesigning UConn’s Database Locator
Redesign Goals
• Web & database usage statistics greatly outweigh individual library-user contact
• UConn Libraries “Plan 2010” Goal 2: Scholar’s Portal says:– “Provide immediate, unmediated, and
comprehensive access to digitized research and scholarly collections worldwide.”
• Peter Morville: “Make Things Findable”
Redesign Timeline
• Began Winter 2006: “database descriptions too long, fix”– All agreed. But …– Rewriting database descriptions wouldn’t
solve all problems.– “Maybe we should do more”
• Ad hoc group started meeting spring 2006 & set up plan
• Rolled out final version spring 2007
Usage Log Analysis
March - May 2006, UConn patrons …– Performed a keyword
search 15,800 times; and – Clicked on Databases by
Title 6,600 times;– Used the subject browse
