Abstract
A method of adjusting the size of an area to be deleted in a pen-based computing system is provided. An electronic pen may include an eraser end. The eraser end may be used to contact the display surface of a computer system. Application of pressure to the display through the eraser end of the electronic pen may result in the deletion of the text indicated by the position of the electronic pen. As additional pressure is applied, the size of the area to be deleted increases. The invention provided may be used with both pixel type and stroke type erasing systems and provides an efficient and accurate method of deleting electronic ink.
