Design, we conducted two studies of people's social judgments about this topic. In Study I, 750 people were surveyed as they walked through a public plaza that was being captured by a HDTV camera and displayed in real-time in the office of a building overlooking the plaza. In Study II, 120 individuals were interviewed about the same topic. Moreover, Study II controlled for whether the participant was a direct stakeholder of the technology (inside the office watching people on the HDTV large-plasma display window) or an indirect stakeholder (being watched in the public venue). Taking both studies together, results showed the following: (a) the majority of participants upheld some modicum of privacy in public; (b) people's privacy judgments were not a one-dimensional construct, but often involved considerations based on physical harm, psychological wellbeing, and informed consent; and (c) more women than men expressed concerns about the installation, and, unlike the men, equally brought forward their concerns whether they were The Watcher or The Watched.
