Claim One:
1. A method of deleting information displayed on a screen associated with a computer system, the method comprising the steps of: detecting a pointer created stroke input onto the display screen, the stroke being defined as a series of points; processing the stroke for scrub gesture recognition, the stroke processing steps including the substeps of defining a multiplicity of corners in the stroke, removing selected corners that have an associated turn angle that is less than a predetermined angle, and removing selected corners that are associated with segments that are shorter than a designated length; determining whether the processed stroke meets the path definition requirements of a scrub gesture based upon characteristics of the processed stroke itself and without comparing the processed stroke to stored stroke objects, and said scrub determining step includes the substep of determining whether the number of times that the processed stroke changes the direction of its turn angles exceeds a predetermined number; determining whether an object displayed on the screen is selected when the stroke is determined to meet the path definition requirements of a scrub gesture; and deleting the selected object if the processed stroke meets the requirements of a scrub gesture and an object is selected for deletion.
