3. Wireframing What is the main idea? –Separate content from layout and display –From last 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?

7. 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

8. 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

13. 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

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

15. Modes What are they? When are they necessary? Why can they be problematic? How can these problems be fixed?

16. Modal Blooper

17. Modal Blooper (and other problems too)

18. Toolglass + Magic Lenses An innovative way to deal with modes: –Make selection of operations visible as you are doing the operations –Work by Fishkin, Stone, and Bier at Xerox PARC

19. Toolglass & Magic Lenses A palette of tools Applying the fill-color tool Composing two tools – Fill-color and magnify

20. Toolglass + Magic Lenses Magic Lenses are windows which know about what’s below them, and/or what’s above them. –Using them makes the mode explicit –They can alter input, output, or both. –They can be combined See video
