Mobile content is twice as difficult [usability] — from Jakob Nielsen

When reading from an iPhone-sized screen, comprehension scores for complex Web content were 48% of desktop monitor scores.

It’s more painful to use the Web on mobile phones than on desktop computers for many reasons:

  • Slower downloads
  • No physical keyboard for data entry
  • No mouse for selection; no mouse buttons to issue commands and access contextual menus (indeed fewer signaling states, as discussed further in our seminar on Applying HCI Principles to Real World Problems: a touchscreen only signals “finger-down/up,” whereas a mouse has hover state in addition to button press/release)
  • Small screen (often with tiny text)
  • Websites designed for desktop access instead of following the usability guidelines for mobile
  • App UIs that lack consistency

New research by R.I. Singh and colleagues from the University of Alberta provides one more reason: it’s much harder to understand complicated information when you’re reading through a peephole.
