Chameleon Devices: Investigating More Secure and Discreet Mobile Interactions via Active ...
summary
An Android app prototype captures a photo of the placement surface, lets users define image areas glow cues for SMS/WhatsApp/Facebook, and triggers a hand-over replay to re-show missed alerts. The app is deployed on participants’ own phones in a five-week field study across a Cape Town township and the UK. Emergent users report increased discretion and some security benefit but demand stronger camouflage, lower power draw, and alternatives when surfaces are plain; UK users value reduced social disruption.
