1. Prof. Anselm SpoerriWeb Design Summary1 Web Guiding Principles Diversity of Users & Rapid Change –Diverse users, diverse computers, diverse skills, diverse … –Rapid evolution of technology and expectations –Short attention span Common Sense –No right way to design Make it short –More likely to be read and remembered –Cut in ½ and cut in ½ again Don't make me think –Get rid of question marks - each item has clear purpose Make it work at a glance –People have little time Support intented task - manage expectations

3. Prof. Anselm SpoerriWeb Design Summary3 Design Implications Scan pages - don't read them Design for Scanning Make text short - cut words Make page work at a glance Sufficient left margin, 640x480 = main message Create Visual Hierarchy Look for anything = Search Interest Decide quickly Choose first “reasonable item” Make obvious what you can do on a page Make obvious what is clickable Muddle through Don't figure out how things work Resist forming models Don't make users think Get rid of question marks Each item = clear purpose Stick to what works Repetition & Consistency Grid Layout, Easy Navigation, Graphics, Color Coding, Typography

5. Prof. Anselm SpoerriWeb Design Summary5 User Behavior  Design Implications  Design Specifics 2 Create Visual Hierarchy & Guide Eye Important Things = Visually Prominent (More Important = Larger / Sharp Contrast) Use headlines to guide the eye Visual Contrast Use sharp changes in size (headline), light intensity (bold), color, texture, motion to create contrast. Proximity: related things spatially close Spatial separation = conceptual separation. Don't mix alignment styles. Use Grouping & Nesting to Increase Information Density (Short-term Memory = 3-7) Use bounding shapes.

8. Prof. Anselm SpoerriWeb Design Summary8 Requirements for Web Pages  Layout Presents Info Clearly & Logically Facilitates Understanding & Recall  Visual Hierarchy Guides Eye to Important Things Where do I start? What can I do here? What site is this? What page am I on? Options at this level? Where I am? Go higher or home? Major sections of site? Web Page needs to easily answer Web Navigation needs to easily answer  Site ID – logo, image, text  Page name  Primary Navigation Top Row or Left Column Simple text hyperlinks, icons, rollovers, image-maps, pull-downs  Secondary Navigation Below Top Line or Left Column  Expanding / Nesting Hierarchies Static or Dynamic Outlines  Color Coding, Breadcrumbs Primary / Secondary Navigation

9. Prof. Anselm SpoerriWeb Design Summary9 Basic Design Principles Alignment –Don't Mix Alignment Styles - Simplicity –Create Sufficient Left Margin –Constrain Total Width of Page Proximity –Related Things Close Together –Spatial Separation = Conceptual Separation Repetition & Consistency –Grid Layout, Navigation, Graphics Color Coding, Typeface –Creates Ease of Use Contrast –Bigger, Bolder, Color, Spatial Distance –Guide the Eye and Create Visual Hierarchy

10. Prof. Anselm SpoerriWeb Design Summary10 Writing for the Web Concise, SCANABLE and ObjectiveConcise, SCANABLE and Objective by Jacob Nielsen People scan page –Study: 79% always scanned + only 16 % read word-by-word. Make pages “scanable” –Start with conclusion –One idea per paragraph –Half the word count (or less) than conventional writing –Highlighted keywords –Meaningful sub-headings (not "clever" ones) –Bulleted lists Credibility important and increased by: –High-quality graphics –Good writing –Use of outbound hyperlinks
