Abstract
The tracking of physical entities within a space such that computer-implemented computations (or ambient computing) may be performed on the features and/or activity of physical entities within that physical space. A space-time data structure corresponding to the physical space is set up. For at least one physical entity within that physical space, physical feature(s) of the physical entity is sensed at different instances in time. That sensed feature is stored in an entity data structure that is associated with the space-time data structure. This may be done for multiple physical entities within the location using multiple entity data structures that are each associated with the space-time data structure. A computing system may navigate such a space-time data structure to perform computation on physical entities, physical features and physical activity within that physical space.
