Abstract: Make available, to a plurality of administrators of a plurality of wireless local area networks, a portal that permits specification of messages to be displayed to potential users of the wireless local area networks. Obtain, by a wide area network operator, via the portal, a plurality of messages associated with the plurality of wireless local area networks, to be provided to putative users of the plurality of wireless local area networks. Selectively provide (i.e., from the wide area network operator) at least a subset of the plurality of messages to corresponding ones of the putative users.

Abstract: Real-time two-way communication between a user immersed in a virtual reality (VR) environment and another party who is not in the VR environment. The sequence of video frames being presented to the VR user on, e.g., a head mounted display, i.e., the VR user's “field of view” in the VR environment, is shown to a guest user on their computing device. Simultaneously, video from a camera in a guest user computing device is shown to the VR user in a window in the VR environment. Audio is also exchanged in real time between the VR user and guest user by use of a microphone and loudspeaker in both the VR system and the guest user computing device. The VR user's system can also support both rotational and translational user movement thus properly changing the VR user's apparent distance from objects displayed in the VR environment.
