Paper Prototyping a case study at Cornell University Library Melissa Kuo DLIT Usability Seminar March 20, 2007
What is paper prototyping? • "Paper prototyping is a variation of usability testing where representative users perform realistic tasks by interacting with a paper version of the interface that is manipulated by a person ‘playing computer,’ who doesn’t explain how the interface is intended to work." Source: Paper Prototyping: The Fast and Easy Way to Design and Refine User Interfaces (Snyder, 2003)
Why use paper prototyping? • Conceptual, high level, early stages of design • Quick and easy to change • All team members could participate • Users feel more free to respond, interface seems more changeable • Alternative to electronically-generated wireframes, Photoshop comps, HTML prototypes
Possible findings (modify this slide for easier flow of talking?) • Usability issues • Example: bad labels, layout problems, navigation • Missing functional requirements • Example: search features • Preference for one design alternative • Example: drop-down list vs. checkboxes • Priorities • Example: browse by category vs. browse A-Z list • Issues outside the user interface • Example: using Gateway vs. never using it Source: Paper Prototyping (Snyder, 2003)
Case Study: WebFeat Implementation • Basic layout ideas • New service • Web development by WebFeat
The process • form usability sub-group • consult with A&U group • formulate key tasks and test questions • get materials and create prototypes • recruit and schedule subjects • run tests • discuss results, make changes, rinse and repeat
Key Tasks • Find articles on a topic • Find images • Locate and search a specific database • Locate a particular e-journal
Sample Questions • Find some articles on the musician Dorsey Harvey. • How would you find an image of an art nouveau painting? • Find an article in the database Agricola. • Find the journal Psychology and Law. • Others… • Find the book Catcher in the Rye by J.D. Salinger. • Once you got a list of results, how would you email them to yourself?
How to cut paper and glue stuff • Low fidelity vs. high fidelity prototypes • Don’t have to draw straight lines • Materials include: • Drawing pad, markers, scissors, removable tape, restickable glue, white-out, index cards, paper
The test • Olin 111B • Facilitator, “Computer”, Note-taker • Meet students at reference desk • Introductions, review consent form • “testing the system, not you” … “no wrong answers” • Run through questions • room for flexibility, limited prompting of subjects • Subject questions? • Sign receipt, see ya
Reviewing data, making revisions (flesh this out, what to say) • Transcribe notes, post to wiki • Sub-group and group meeting • Changes between rounds
Observations (flesh out) • Interesting responses from subjects • What comments are worth making changes? • It was fun!
