ABSTRACT:
A method for selecting objects displayed on a screen of a pen-based computer system characterized by the steps of: (a) determining that a selection gesture has been made on the screen of the pen-based computer by a stylus; (b) detecting a path made by the stylus across at least a portion of an object depicted on the screen; (c) displaying a line image on the screen along the path; (d) determining a selection of at least a portion of the object as indicated by the path; and (e) displaying selection indicia on the screen representing the selection. The step of displaying the selection indicia can occur concurrently with or after the complete path is made by the stylus on the object. Preferably, the line image is removed after the step of displaying the selection indicia.
