Today Discuss Assignment 3 Wireframing Card Sorting

Wireframing What is the main idea? –Separate content from layout and display –Next week: Use the page layout to signal the flow of interaction Group conceptually related items together –Nielsen: What does the layout communicate? Test if a page of content becomes more usable because of the layout A template (for a home page) should contain what items?

How WireFraming Fits In Kelly Goto & Eric Ott of Macromedia edia/monterey/architecture/

From

How to Test A Layout Study conducted by Thomas S. Tullis from Fidelity Investments in 1998 Assessed the usability of five alternative template designs for their intranets. Method: –Show templates with “greeked” text –Draw labeled boxes around each page corresponding to 9 elements –No overlapping allowed –Indicate if something appears not to be there

The Elements 1.Main content selections for this page 2.Page title 3.Person responsible for this page 4.Intranet-wide navigation (e.g., intranet home, search) 5.Last updated date 6.Intranet identifier/logo 7.Site navigation (e.g, major sections of this section of the intranet) 8.Confidentiality/security (e.g, Public, Confidential, etc.) 9.Site news items

From

Nielsen Wireframing Example Different parts of the designs scored better Best parts were taken from each design and combined Resulted in an overall better score

Results of Study Correct Page Elements Subjective Appeal (-3 to +3) Template 152%+1.3 Template 367%+0.9 Final Design72%+2.1

Card Sorting Main purpose? –Determine how to organize a set of information –Determine good labels for the items in that organization How is it done? –User-centered Write topics on cards Ask different participants to organize them for a given task –Need strategies for “difficult” cards Consolidate the results –Do another round for labels
