ABSTRACT:
Methods, systems, and apparatus, including computer program products, for processing graphical input. Input that specifies a path is received. The path includes multiple locations ordered along the path. A tracking zone is specified for each of the multiple locations based on the location and a previous location preceding the location along the path, where the tracking zone indicates a direction of the path at the location. A backward motion is detected between a first and a second location in the path if the first location's tracking zone overlaps with the second location's tracking zone. If a backward motion is detected between the first and second locations, a portion of the path connecting the first location to the second location can be replaced.
