A computer system and method of operation thereof are provided that allow interactive navigation and exploration of spatial enviroments, both real and virtual. The computer system employs a data architecture comprising a network of nodes connected by branches. Each node in the network represents an intersection in the real environment that allows a user of the computer system to select which path to follow. Likewise, each branch in the network represents a path connecting physcial intersections in the real environment. The network is constructed directly from a map of the target environment. Navigation data such as image frame sequences, intersections between paths, and other related information are associated with the elements of the network. This establishes a direct relationship between locations in the environment and the data which represent them. From such an organization, the user may tour the environment, viewing the image sequences associated with each path and choosing among intersecting paths at will. The computer system of the present invention is suitable for applications such as developing training materials for complex procedures, building video games or interactive exhibits, authoring stories with multiple alternative endings, creating virtual shopping malls and virtual stores, or allowing virtual visits to remote sites (e.g., museums, historic sites, etc). |
