Privacy itch and scratch: on body privacy warnings and controls

In the age of ubiquitous computing increasing amounts of personal data are being logged and shared, making privacy management a challenging task that must be integrated into our daily lives. In this paper, we explore the metaphors of ‘privacy itch’ for warnings and ‘privacy scratch’ for control of privacy preferences through real time, on-body, haptic interaction technologies. To assess the utility of these concepts, we implemented a forearm wearable prototype: the Privacy Band, and conducted a small lab-based user study.
