Automatic and interactive animation driven by change-based heuristics

Abstract

Techniques for performing automatic interactive animation by automatically matching objects between multiple artboards, allowing an animator to link multiple artboards in a temporal sequence using time as a trigger and allowing an animator to preview an animation using intuitive drag controls via an input device such as a mouse or touch screen. An automatic animation process is performed by matching objects/nodes between artboards by determining a ranking of similarity between objects based upon a distance metric computed for a set of one or more attributes associated with each object in the artboards. If sufficient match is found, the matched objects can be treated as a single entity to be animated. In another embodiment, dominant direction of movement with respect to the matched objects is determined, and receipt of a drag event (mouse input or touch screen gesture input) in said dominant direction causes a preview of animation of that entity.
