Method, apparatus, and program product for modeling presence in a persistent virtual environment

摘要

Apparatus, methods, and computer program products are disclosed that accumulate a presence history of an entity within a persistent virtual environment by repeated gathering of virtual presence information. The virtual presence information includes an entity identification value and a sampling time value. Once the virtual presence information is collected, the technology performs a general least-squares-fit to a set of basis functions on a portion of the presence history to create a coefficient vector. The coefficient vector represents a temporal profile consistent with the presence history and includes coefficients responsive to the general least-squares-fit. Once the coefficient vector is created, the technology characterizes the entity responsive to its coefficient vector and presents the characterization of the entity.
