UI design choices.

Filed under: Technology, programming — Prakash Muralidharan @ 5:17 pm

UI design is something that receives less importance compared to the holy grail of coding. But we all hate websites with crappy layouts and cumbersome navigation structures. I came across this really neat tradeoff matrix on UI design by Mike Padilla.

DesignBenefitCost
Shallow information architectureFewer clicks to find infoMore clutter
Deep information architectureClean, reduced clutterMore clicks to find info
Small fontMore information per screenMore difficult to read for some users
Large fontEasier to readLess information per screen
Drop-down boxSelection amongst many choices using limited spaceHidden choices
Radio buttonsSee all selections at all timesAdditional space required, clutter
IconsQuick recognition once learned, aesthetically pleasingMust be learned
Text linksAlways understoodMust be read, do not stand out as actionable items as much from other text
AbbreviationsSave spaceMust learn or recognize
Full textEasily understoodRequires additional space
Keyboard shortcutsHigh speed of data entryMust be learned
Point and clickIntuitiveAdditional time required for interaction due to increase motor skills required

Mike goes on to suggest the following factors to judge a UI:

  • Ease of learning and memorability
  • Efficiency of use
  • Error frequency, severity, and recovery
  • Subjective satisfaction

  • Linking and Sharing
