Abstract

A method of and system for facilitating stylus input into a text entry field in a pen-based computer system. The system detects a touch down of a stylus and determines whether the touch down is in a text entry field. Upon detection of movement of the stylus in the text entry field greater than a threshold, the system draws an include rectangle around the text entry field. The system sizes the include rectangle based on the size of the text entry field. The system interprets and completely inks any stroke of the stylus starting within the include rectangle within a predetermined timeout as an input to the text entry field. The system erases the include rectangle whenever it detects a stylus touch down outside the include rectangle, or the predetermined timeout expires without the system detecting a stylus touch down.
