Usability Goals and Guidelines

Goals

Nielsen's framework

  • Learnability
  • Efficiency of use
  • Memorability
  • Few and noncatastrophic errors
  • Subjective satisfaction

Components

Desktop

Affected: PinPuppy, icons,fonts, wallpaper
Icons and description must be clear and self-evident
Only the most important things belong on the desktop. If it is not needed to be present to the user, it has to go
Allow long working hours: high contrast, legibility, font size, icon size
Appealing to a broad audience

Menu

Repeatetly used programs should be prominently placed
Self-explanatory structure; think about non-experts !
As a rule of thumb about 5-7 items per group of elements
First access is usually with a task in mind and guided by guessing from the context, e.g. check email. Structure should be grouped by action, description should start with the action it is supposed to do (not "Sylpheed Email-Reader", better "Email reader (Sylpheed)" ).
Succesive access is guided by recall of signals: words, icons, position. Give non-biased signals.
Check every item over and over on functionality; give feedback to the user

Wizards

Applications

- Subjective satisfaction
I don't like that ROX resizes it's windows by default. takes a while to find where to switch that ... off

important buttons should be on the right hand side by convention. The "save" button in the Ethernet wizard after load/config is on the left though.
