System and Method for On-Demand Pricing Using Complex Event Processing

A Virtual Universe (VU) is a computer-based simulated environment intended for its users (aka: residents) to traverse, inhabit, and interact with one another through the use of avatars. Many VUs are represented using 3-D graphics and landscapes, and are populated by many thousands of residents. Other terms for VUs include metaverses and "3D Internet."

Often, the VU resembles the real world in terms of physics, houses, and landscapes. VU concepts are defined as follows:
• An avatar is a graphical representation the user selects that others can see, often taking the form of a cartoon-like human.

• An agent is the user's account, upon which the user can build an avatar, and which is tied to the inventory of assets the user owns.

• A region is a virtual area of land within the VU, typically residing on a single server

• Assets, avatars, the environment, and anything visual consists of unique identifiers (UUIDs) textures (distributed to users as graphics files such as JPEG2000 files), and effects data (rendered by the user's client according to the user's preferences and user's device capabilities).

• Teleport offer: An offer to instantaneously travel directly to a specific location

Objects in a virtual universe are composed of one or more primitive objects such as cones, triangles and polygons. The more detailed an object, (i.e., the more primitive objects in its composition) the longer it takes to render and download. It is common for virtual world parcels to incorporate many objects in their design.

Complex Event Processing (CEP


Complex Event Processing, or CEP, is primarily an event processing concept that deals with the task of processing multiple events from an event cloud with the goal of identifying the meaningful events within the event cloud. CEP employs techniques such as detection of complex patterns of many events, event correlation and abstraction, event hierarchies, and relationships between events such as causality, membership, and timing, and event-driven processes.


In this disclosure, Events has two meanings. The first meaning is tied to complex event processing in which individual actions or events are analyzed as described above. The second meaning of an event is a gathering in which individuals would pay to participate. Virtual events can be concerts, movies, performances, etc.

Presently, adequate methods do not exist to assist entities in properly setting prices for events within a virtual universe. As virtual worlds gain popularity for personal and business relationships it will become increasingly important to set prices commensurate with interest in the event.

The disclosed invention defines methods to assist in event pricing within a virtual universe. Upon detection of incorrectly priced events the proposed invention performs some of the following actions:
1. Notifies event owners of pricing not commensurate...
