Interactive point-of-view authoring of digital video content using a resizable overlay window and a cylindrical layout
First Claim
1. An interactive, electronic method of authoring annotated traversals through visual data, the method comprising:
- displaying the visual data;
interactively defining a traversal of the displayed visual data by positioning a resizable overlay window relative to the displayed visual data, wherein said resizable overlay window is resizable while the visual data is being displayed, said traversal comprising a subset of motion video that specifies a time-based sequence of frames of said motion video, each of said frames comprising the visual data delineated by the overlay window, wherein the displaying said visual data comprises displaying the visual data in a cylindrical layout, and wherein said positioning of the overlay window is defined by a field of view of a virtual camera located centrally to said cylindrical layout;
annotating the traversal; and
storing a persistent record of the annotated traversal.

Abstract
The present invention provides electronic methods and apparatus for interactively authoring, sharing and analyzing digital video content. Methods for authoring include displaying visual data, defining each traversal as a time-based sequence of frames and annotating and storing a record of the traversal and its associated audio records. Defining the traversal Includes interactively panning the visual data by positioning an overlay window relative to the visual data and zooming in or out by resizing the overlay window. In alternative embodiments, the visual data may be displayed in a rectangular layout or a cylindrical layout. The methods are practiced using an integrated graphical interface, including an overview region displaying the visual data, a detail region displaying current data within the overlay window, and a worksheet region displaying a list of previously stored annotated traversal records. In a further aspect, the worksheet region list of annotated traversal records is published in a web document accessible via network using a standard HTML browser, and further annotations may be added by a community of network users. Analytical methods are also provided in which data markers corresponding to traversal records are plotted against an interactive abstract map enabling users to shift between levels of abstraction in exploring the video record.
