What you'll learn

Key ideas in The Digital Architect: From Pixels to Packets

  • High contrast colors draw the eye to the primary action first
  • Whitespace acts as a spotlight by removing competing visual noise
  • Lowering the visual weight of secondary buttons prevents confusion
  • Crowded elements compete for attention and lose individual impact
  • Contrast and weight in button design
  • Whitespace and crowding
  • Largest text indicates the starting point of the information
  • Uniformity forces the brain to work harder to find a starting point
  • Decreasing sizes signal the relationship between main ideas and details
  • Lack of hierarchy leads to 'choice paralysis' or user frustration
  • The effect of whitespace on perceived importance
  • Using font sizes to create a logical scanning path
  • Consequences of lack of hierarchy on cognitive load
  • The most important element is the one that completes the user's goal
  • Hierarchy should follow the primary intent of the specific screen
  • Users look for keywords and bold headings rather than full sentences
