Abstract
Abstract Disclosed is a computer system user interface in which the user is provided with a visual indication of whether or not a source object is over a valid target object during direct manipulation operations. A shadow is displayed behind the source object. When the source object is over a valid target, the size of the shadow is reduced or eliminated to give the appearance that the source and target are attracted to each other. When the source object is over an invalid target, the size of the shadow is increased to give the appearance that the source object is repelled by the target object.
