Memory and Site Structure

This study emphasizes the significance of unassisted recall in web design, focusing on memory aids and information structure. While many websites incorporate memory aids, the quality of these aids and how information is organized is crucial for user experience. By understanding what users want to achieve on your site through task analysis, you can better structure information. This guide discusses practical strategies, such as chunking data and maintaining link consistency, to create a user-friendly web environment that enhances navigation and usability.

Presentation Transcript

  1. Memory and Site Structure ITC 200

  2. Concept of +/- Seven • Remember: this study focused on unassisted “recall” -- otherwise known as memorization • Most web sites include memory aids • The quality of the memory aid is another discussion!

  3. Information Structure • For web sites, information structure is usually more important than the “+/- 7” rule • Chunk data • Impose order where there is none (number, alpha sequence)

  4. Task Analysis • To effectively structure your information - you have to know what your web site customers want to do on your site! • This is also known as task analysis

  5. A Real Life Example • The next slide is a screen capture of a drop-down menu on the Washington State Attorney General’s web site • Notice how structure has been created • Can you easily make a selection from the (considerably longer than seven) list? Why or why not?

  6. Secondary Links • Do you like the way the designer treats the secondary drop-down link in the following screen capture? Why or why not?

  7. Link Consistency • On the following slide, does the lack of consistency in link wording confuse? Why or why not? • Does the lack of consistency in number of links in drop-down versus category index page confuse? Why or why not?

  8. Resources • Anything by Edward Tufte • User and Task Analysis for Interface Design • Information Exploration and Visualization : http://www.awl.com/dtui/chapters/ch15.html • Task Analysis Tutorial: http://uml.tutorials.trireme.com/uml_tutorial_4_1.htm • User-Centered Analysis and Conceptual Design: http://www.humanfactors.com/training/useroriented.asp • Web Site User-Centered Design: http://www.internettg.org/newsletter/june98/user_requirements.html
