Abstract: The disclosed technology includes systems and methods providing event- or condition-based notifications of device mirroring responsive to one or more of changes in the physical or internal environments of a computing device, for example a mobile computing device. Moreover, some implementations may include stopping or suspending device mirroring responsive to the same. A change in the physical environment of a computing device may be determined from a change in a signal received at the device, for example a network connection signal, IR signal, or ambient light or noise level. A change in physical environment may also be determined based on a change in location or orientation of the computing device. A change in the internal environment of the computing device may include a change in the active application at the device, or a change in focus to a new application.
