Abstract: Methods and devices provide a user interface that provides visual cues when a document pan or scroll has reached an end or boundary by distorting the document image in response to further user inputs. The image distortion functionality may include shrinking, stretching, accordion expansion, or bouncing of a document image. The degree of image distortion may be proportional to the distance that a user input would have the document move beyond the encountered boundary. When a boundary of a document image is reached during a rapid pan or scroll, a bouncing image distortion may be applied to the document image to inform the user that the document reached a boundary during the movement.
