Enhancing Mobile Content Privacy with Proxemics Aware Notifications and Protection
summary
A tablet prototype uses an electromagnetic motion tracker and headband tracking to detect onlookers within about five feet, popping a glyph notification and applying visual protections (grayscale, dim screen, selective anonymization or a mask protection viewport). A Wizard-of-Oz field test (12 participants) and a lab study (26 participants, baseline vs notification vs protection vs both) show higher perceived awareness and usability; users prefer masks for precise finance tasks and dimming for general use, but 12 participants report mistrust in tracking accuracy.
