Permissions: Do Icons Help Comprehension?Ariel Haney, Serge Egelman, Nathan Good, David Wagner
  • SURVEY 2: CONTROL CONDITION
  • SURVEY 2: EXPERIMENTAL CONDITION
  • SURVEY 2: PRELIMINARY RESULTS
  • CONCLUSIONS
  • Users understand icons better than the current text explaining Android permissions.
  • Future work to improve icons’ ability to signal inappropriate runtime permissions.
  • Past studies have demonstrated that a significant number of users don't notice permission warnings.1
  • Of those users that do notice them, many misunderstand their meaning.1
  • Icons have been shown to increase warning comprehension.2
  • .
  • PURPOSE
  • Can icons increase comprehension of Android permission warnings?
  • SURVEY 1: INSTALL TIME
  • How do well do users understand icons relating to permissions at install time?
  • This is currently when permission information is shown.
  • SURVEY 1: SETUP
  • What permission is being requested?
  • SURVEY 1: PRELIMINARY RESULTS
  • Although the number of users who understood the permissions was low, these numbers represent a 21%-51% increase in comprehension from textual permission warnings.
  • SURVEY 2: RUNTIME
  • How well do users understand permission icons at runtime?
  • Previous research has shown that warnings are most effective when shown right before the hazard is encountered.2
  • Control condition – The icon is shown above an app that would clearly need the permission. Experimental condition – The icon is shown above an app that is unlikely to need the permission.
