Aggregated data associated with a geographic area may be obtained. The aggregated data may be dynamically distilled to obtain a presentation set of data based on a dynamically changing geographic location associated with the geographic area. A transmission of a stream of personalized audio data that is based on the presentation set of data may be initiated, via a device processor, to a receiving device associated with a user that is associated with the dynamically changing geographic location.

Audio presentation of condensed spatial contextual information

Audio data associated with a plurality of originating sources is obtained, the audio data directed to a participant entity. An originating entity associated with one of the originating sources is determined. A listener focus indication is obtained from the participant entity indicating a listener focus on the originating entity. A spatial positional relationship is determined between the participant and originating entities. A filtering operation is initiated to enhance a portion of the audio data associated with the originating entity, the portion enhanced relative to another portion of the audio data that is associated with the originating sources other than the first one. A spatialization of a stream of the first portion that is based on a participant positional listening perspective is initiated, based on the spatial positional relationship. Transmission of a spatial stream of audio data is initiated to the participant entity, based on the filtering operation and spatialization.

Selective spatial audio communication

Positional information is provided while minimizing the possibility that personally identifiable information can be derived therefrom. Positional information is received in the form of trails that can be aggregated. Individual cells of a grid reflect a quantity of aggregated trails through those cells, an average intensity and direction of movement through those cells, or a more detailed distribution thereof. Alternatively, individual trails are aggregated to an aggregated trail in the form of a line. Further obfuscation of personally identifiable information occurs by resampling aggregated positional information, by introducing false positional information, or by falsely modifying existing positional information, in a manner that does not impact the overall aggregations, and by pruning, or deleting, positional information, especially around sensitive locations, such as a user's home, place of business, or other location that users typically would seek to keep private. Provision of positional information is delayed until a sufficient amount is received.

Depersonalizing location traces

A system for configuring orientation and storing criteria corresponding to vector elements that form a boundary of a polygon is provided. This innovation can define the boundary of a polygon as individual vectors with implied 'from-' and 'to-' directionality and can store the vectors in a standard manner such that they are always aligned in a like orientation. This novel configuration and/or storage mechanism(s) can facilitate efficient spatial operations. Particularly, spatial operations can be enhanced by employing a single formula to compare a reference point to any of the vectors forming the boundary when determining intersection with a boundary vector segment. Additionally, the innovation can employ a novel schema to store vector information into a relational database management system (RDBMS). As such, the data can be used for performing spatial selection operations such as the well-known Point-In-Polygon and Polygon-on-Polygon operations.
