Interactive interfaces to video information provide a displayed view of a quasi-object called a root image. The root image consists of a plurality of basic frames selected from the video information, arranged such that their respective x and y directions are aligned with the x and y directions in the root image and the z direction in the root image corresponds to time, such that base frames are spaced apart in the z direction of the root image in accordance with their time separation. The displayed view of the root image changes in accordance with a designated viewing position, as if the root image were a three-dimensional object. The user can manipulate the displayed image by designating different viewing positions, selecting portions of the video information for playback and by special effects, such as cutting open the quasi-object for a better view. A toolkit permits interface designers to design such interfaces, notably so as to control the types of interaction which will be possible between the interface and an end user. Implementations of the interfaces may include editors and viewers.

[ What is claimed is:] [1.] An interface to an associated video sequence, the interface comprising:a) information defining a three-dimensional root image, the root image consisting of a plurality of basic frames selected from said video sequence, and/or a plurality of portions of video frames corresponding to selected objects represented in the video sequence, x and y directions in the root image corresponding, to x and y directions in the video frames and the z direction in the root image corresponding to the time axis whereby the basic frames are spaced apart from one another in the z direction of the root image by distances corresponding to the time separation between the respective video frames;b) means for displaying views of the root image;c) means for designating a viewing position relative to said root image; andd) means for calculating image data representing said three-dimensional root image viewed from the designated viewing, position, and for outputting said calculated image data to the displaying means.
