Abstract: A mobile electronic device includes a wireless communications interface configured to receive, from a remote device, a sequence of remote device proximity indicators. The sequence of remote device proximity indicators indicate positions of the remote device. A mobile proximity detector of the mobile electronic device is configured to monitor a current position and a current velocity of the mobile electronic device; determine, from the sequence of remote device proximity indicators, a current remote device position and current remote device velocity; and determine, using at least the current remote device position and velocity, and the current position and the current velocity of the mobile electronic device, a likelihood of close contact between a user of the mobile electronic device and the remote device. A notification manager of the mobile electronic device is configured to notify the user of the likelihood of close contact.

Abstract: A system provides a “virtual room” for remotely sharing content experiences via electronic devices at different locations. The system may enable synchronization of the content at the different locations, access control, be able to provide and/or experience interaction feedback regarding the content, control the interaction feedback that is provided and/or experienced, enhance the ability of people to distinguish the content from the interaction feedback, and so on. As such, people may be able to share content experiences more like they were present in a single location while remote from each other.
