Patent ID: 7305611

Claim:
A computer-implemented method of creating an interactive visual lesson, comprising: creating a lesson map identifying a plurality of pages that constitute the interactive virtual lesson, each of the pages including a different interactive view of a three-dimensional model having a three-dimensional space, the respective interactive views of the three-dimensional model being defined by coordinates in the three-dimensional space; displaying a page selected from the plurality of pages on a graphical user interface of a computer, which selected page includes an interactive view of the three-dimensional model; drawing an annotation on the three-dimensional model included in the displayed page, the annotation being defined by coordinates in the three-dimensional space of the three-dimensional model; defining, in connection with the annotation drawn on the three-dimensional model included in the displayed page, a link to an arbitrary page different from the displayed page and selected from the plurality of pages that constitute the virtual lesson; navigating through the interactive virtual lesson in a non-linear fashion by activating the link defined in connection with the annotation drawn on the three-dimensional model; and displaying the arbitrary page linked to the annotation.
