Out of sight, out of mind: Effects of displaying access-control information near the item it controls

We take a detailed look at how users, while focusing on non-permission tasks, notice and fix access-control permission errors depending on where the access-control policy is spatially located on a photo-sharing website. The access-control policy was placed on an online photo-sharing website under the photo or album, on the sidebar, or on a separate settings page. We find that placing the access-control policy directly under photos and album thumbnails improves participants' ability to notice errors in their access-control settings without negatively impacting non-access-control tasks. © 2012 IEEE.
