  1. Golden rules of design from one screen looking out

  2. Four golden rules of design • knowing where you are • knowing what you can do • knowing where you are going (with respect to goal) • or what will happen • knowing where you’ve been (with respect to goal) • or what you’ve done

  3. top level category sub-category web site this page live links to higher levels Knowing where you are – breadcrumbs • shows path through web site hierarchy

  4. knowing what you can do • What is active what is passive • where do you click • where do you type • consistent style helps • e.g. web underlined links • Labels and icons • standards for common actions • language – bold = current state or action

  5. knowing where you are goinggoal seeking goal start

  6. knowing where you are goinggoal seeking goal start progress with local knowledge only ...

  7. knowing where you’ve been-goal seeking goal start … but can get to the goal

  8. goal start knowing where you’ve been-goal seeking … try to avoid these bits!

  9. user action and control entering information knowing what to do affordances

  10. Name: Alan Dix Address: Lancaster Name: Alan Dix Address: Lancaster Name: Alan Dix Address: Lancaster Entering information • Forms, dialogue boxes • Presentation + data input • Similar layout issues • Alignment - N.B. different label lengths • Logical layout • Use task analysis • Groupings • Natural order for entering information • Top-bottom, left-right (depending on culture) • Set tab order for keyboard entry  ?

  12. Colour and 3D • Both often used very badly! • Colour • Older monitors limited palette • Colour over used because ‘it is there’ • Beware colour blind! • Use sparingly to reinforce other information • 3D effects • Good for physical information and some graphs • But if over used … e.g. text in perspective!! 3D pie charts

  13. baduseofcolour • overuse - withoutverygood reason (e.g. kids’ site) • colour blindness • poor use of contrast • do adjust your set! • adjust your monitor to greys only • can you still read your screen?

  14. Across countries and cultures • localisation & internationalisation • changing interfaces for particular cultures/languages • globalisation • try to choose symbols etc. that work everywhere • simply change language? • use ‘resource’ database instead of literal text… but changes sizes, left-right order etc. • deeper issues • cultural assumptions and values • meanings of symbols • e.g tick and cross … +ve and -ve in some cultures … but … mean the same thing (mark this) in others  
