摘要:
A system and method is described for constructing a proximity-based ad hoc network among a plurality of sensors and for using such a network to perform location tracking. The system and method uses time-coded data received from each of the sensors to determine a current proximity of each of the sensors to one or more beacons. Then, by leveraging information relating to the effective transmission ranges of the beacons, the system and method determines the relative location of each of the plurality of sensors with respect to other sensors within the plurality of sensors. Where actual (as opposed to relative) location information is available for a particular sensor, it can be used to generate or augment location information associated with other sensors known to be spatially and temporally proximate to the particular sensor. The current location information for each of the sensors is then used in providing location-based services.
摘要:
A system and method is described for constructing a proximity-based ad hoc network among a plurality of sensor-enabled devices and for using such a network to facilitate data sharing among users of those devices (referred to herein for simplicity as “sensors”). The system and method advantageously enables data to be shared among co-located sensors in a manner that does not require local connections or communication among those sensors and that protects user privacy. The system and method also beneficially enables data to be transferred among heterogeneous sensor types that would otherwise be incapable of detecting and/or communicating with each other. The system and method may perform user-initiated data transfer as well as automatic data transfer responsive to sensor proximity and other factors, such as commonality of user interests or activities or membership in a social network.

摘要:
A system and method for selecting and presenting media on a network to tune an environment to the tastes of the users within that environment, thus improving the experience of that location. A physical location of a media presentation device is received over a network. The physical location of a plurality of end users are identified via the network, wherein each of plurality of users associated are with a plurality of media files stored on the network. A least one of the end users that are within a defined proximity to the media presentation device are identified. At least one media file associated with the end users that are within a defined proximity to the media presentation device are identified and transmitted over the network to the media presentation device.
摘要:
A system and method for determination and display of personalized distance. A request is received for the determination of a personalized distance over a network, wherein the request comprises an identification of a requesting user, and a plurality of real world entities comprising at least a starting location and an ending location. At least one route is determined between the first location and the second location. Spatial, temporal, topical, and social data available to the network relating to the requesting user and each real world entity and the route is retrieved using a global index of data available to the network. A personalized distance is calculated via the network between the first location and the second location using spatial, temporal, topical, and social data relating to the requesting user and each real world entity and the route. A representation of the personalized distance calculated for the route is displayed on a display medium.

摘要:
A system and method for presentation of media related to a context. A request is received over a network from a requesting device for media related to a context, wherein the request comprises at least one criteria. A query is formulated based on the context criteria so as to search, via the network, for user profile data, social network data, spatial data, temporal data and topical data that is available via the network and relates to the context and to media files so as to identify at least one media file that is relevant to the context criteria. A playlist is assembled via the network containing a reference to the media files. The media files on the playlist are transmitted over the network to the requesting device.
