Three dimensional virtual reality enhancement techniques
For a world that has a portion of the world distant from the point of view of the user represented in only two dimensions as a video on a video screen, when an object on the video screen undergoes a trajectory that takes at least a portion of it to a location in the world that is not represented by the video but instead is a location in the world that is represented by computer graphics, in addition to being able to continue to see such an object when it is rendered as computer graphics in the computer graphics part of the world, i.e., popped out from the video, one is able to interact with such an object. Thus, an object which pops out from a video into the computer graphics part of the world may be "investigated" by a viewer of the world. For example, the user could enter a store which popped out of the video, and engage in virtual shopping therein. The particular store which is actually entered may be customized on a per user basis, e.g., as a function of geography. When the proprietor of a virtual store, or his representative, e.g., electronic agent, detects the avatar of one or more persons in the vicinity of the avatar of a store for which such proprietor's store corresponds to the virtual store for such passing persons, a message may be transmitted to such passing persons.
