PRIVACY SAFEGUARDS FOR PROJECTING CONTENT ONTO A SHARED DISPLAY DEVICE

摘要

A technique allows a user to project content onto a shared display region in a controlled manner. The technique involves receiving context information that describes a context in which a user is currently interacting with a local user computing device. The technique then determines, based on policy logic and the context information, whether it is appropriate to invoke a private state, or to remove the private state and enter a shared state. The private state involves presenting a privacy screen on one or more shared display regions. The local user computing device remains connected to the display device(s) that host the shared display region(s) while operating in both the private state and the shared state. According to one advantage, the technique eliminates or reduces the risk that the user will inadvertently release private information to others; further, it does so without asking the user to perform burdensome preparatory actions.
