SURVEY 1: PRELIMINARY RESULTS

1. 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. • Work Cited • 1A. P. Felt, E. Ha, S. Egelman, A. Haney, E. Chin, and D. Wagner.
