US Patent 8682300 Adaptation of notification perimeter based on relevance to a user

Location-based notification architecture that provides notification relevance to a user and/or a user goal. The size of the virtual perimeter or boundary is changed dynamically based on changes in relevance to a user and/or user goal, and thus, can be made dependent on various factors. The size of the perimeter can increase or decrease according to user preferences that are learned over time (e.g., preference for a gas station of a specific company). These capabilities improve the relevance of the notification the user receives. The relevance of a notification to the user can be improved by tuning the perimeter size according to known parameters that depend on the point of interest (e.g., business) itself and/or by tuning of the size of virtual perimeter according to parameters associated with user behavior. Other parameters can be considered as well, such as environmental conditions, and traffic conditions, for example.
