What is Usability?Usability of Digital LibrariesUser-centered DL designMethods of Usability EvaluationIE Lab @ UMC
What is Usability?
Usability is the degree to which an actual customer can use a product or service, such as a Web site, software application, or online store - to perform a typical task or achieve a particular goal.
What is Usability? cont.Jacob Nielsens definition:LearnabilityEfficiencyMemorabilityMinimum errorsSubjective satisfaction
Usability of Digital LibrariesImportant components: Content Functionality Interface
User-centered DL DesignIt is challenging because:Human information behavior is complex and highly context dependentDigital library technologies are rapidly evolving
Changing Information Environment From physical structures .
Changing Information Environment cont.to an integrated electronic environment in motionAlways accessibleHyperlinkedMultimediaWirelessMobile
How to Approach DL Design?Understand users information needs and information seeking behavior in their everyday life contextDesign process should be process-oriented and iterative, not product-oriented and summative
How to Approach DL Design? cont.
Identify your users (not only regular suspects)Find out what is being done to know the users (you may be already doing a lot)Take a dynamic/holistic look at the users (pay attention to their lifecycles, transitions, multiple roles)
What is a DL Usability Evaluation?
It is NOT a single THINGIt is NOT a single EVENTIT IS a PROCESS integrated with all the stages of DL development AND maintenance
Methods of Usability EvaluationParticipatory designFocus group researchSurveysDesign walk throughPaper-pencil evaluationExpert evaluationUsability auditUsability testingField studies
Usability TestingMeasures usability by giving a close-up look at an individual users experience while navigating a site or software application, right down to the users verbal and facial expressions.
Integration of Design & EvaluationStudy users continually and involve them in all stages of the DL design and evaluation processConduct usability testing before, during and after designing new services of DLBe alert to new applications and new user communities
Integration of Design & Evaluation cont.
User-centered DL designRapid prototypingIterative design
Information Experience Lab @ UMCWe conduct research in human information behavior, human-computer interaction and usability methodsWe consult information system developers and researchers at and outside of University of Missouri in usability and information behavior studies. We teach students in usability evaluation techniques and information behavior research methodologies.
Information Experience Lab @ UMCEstablished in 2003 Includes the Information Experience Room (data collection) and the Control Room (research & analysis)Experience Room is set up with five desktopsPortable lab with five laptopsRemote data collection
MoraeAn integrated software application for usability testing Enables developers to measure how usable is their website or information systemPinpoints specific problem areas, and easily share the results
Modern software-based labAll-digital software solution- Eliminates costly, complex hardware and videotapes
Truly portable- Take it anywhere on a laptop
Identify areas for improvement faster- Exclusive Rich Recording Technology
Easy to implement and use- Usability implemented throughout
Project examplesMU Libraries Website Study
Task: Usability evaluation of the MU Libraries website IE Lab helped the library usability team to collect data with Morae.
Project ExamplesUMC Admissions Website study (2006 CASE award winner)
Task: Usability evaluation of the new student admissions website. IE Lab provided the development team with remote, real-time observation of how prospective students and their parents use the website.
Project ExamplesUMC Office of Research Illumination study
Task: How useful is the research magazine website - Illumination to the target audiences? IE Lab conducted one-on-one user interviews and a focus group interview to identify users needs for research information and their interaction with Illumination .
Project ExamplesUMC College of Education Website
Task: Content and task oriented evaluation of the CoE website. IE Lab applied moderated and non-moderated group data collection methodology, enabling better efficiency in Lab space use and short turn-around time for project completion.
Current and Future ProjectsUsability of the MOBIUS website. http://mobius.missouri.edu/. MOBIUS is a consortium of academic libraries with 68 member colleges and universities in the state of Missouri. It provides a virtual collection of 18 million items.Usability of the library website of the TamKang University, Taiwan http://www.lib.tku.edu
