From the background information supplied by the inventors, news correspondents obtained the following quote: "The present invention relates generally to a computer implemented method, data processing system, and computer program product for tracking a moving inventory. More specifically, the present invention relates to modeling assets relative to electronically sensed position of such assets and presenting such assets in a virtual world that models features in the real world.
"Modern uses of networked computers leverage the graphics processing power of client computers. The client computer is a computer typically assigned the task of supporting user input and displaying output to a user. Many users reach online environments called virtual worlds by using a client computer. A virtual world permits a user to adopt an avatar or a graphical representation of the user. The user has the power to move the avatar, have the avatar interact with objects, and have the avatar interact with the avatars of other users.
"A virtual world is the collection of all objects of the virtual world and the virtual areas, if any, associated with the objects. A virtual world may include simulation of object attributes, such as textures and sounds, as well as rules under which real-world physics are simulated or modified, all of which can be supported by a virtual world server. An object can model a real world item, or a prototype of a real world item. Accordingly, an object of the virtual world may be used to simulate solid, liquid, gas and combinations of these materials.
"An example of an object is an avatar. An avatar is an object that represents a true-to-life or a fanciful depiction of a person. The avatar may be rendered in a manner used by the virtual world server to render other objects. In addition, an avatar may serve other functions in addition to those normally associated with an object. An avatar perspective is the combination of the avatar location and attitude. In addition, a perspective may be modified by a stance of the avatar. The viewport may include menus, controls, and messages associated with the viewport to provide information pertaining to the contents of the viewport and to allow user actions upon the viewport.
"A virtual world depends on a coordinate system to create anchor points where avatars and objects may be located for purposes of rendering the avatars and objects to each user's computer. Coordinates are two or more units of distance that define a position in a virtual world. The coordinates may be a Cartesian set of points that define planes and altitudes, however, global coordinates also are known to be used. Typically, an object has a location referenced by a triplet of numbers, and optionally a region or other descriptor of a subset of space within the virtual world.
