Abstract

A pen-based processor needs to be usable to input and edit script in the manner of a text-based computer but retain a resemblance to the user much like a pad and pencil. The pen-based computer implements enable input, editing and other manipulation of handwritten script, ASCII text and drawings in a common document using a compatible internal representation of the data and a simple, consistent set of user control functions. These functions are invoked by the user with an intuitive and interactive set of user gestures which do not distract the user from the task of inputting or editing the document. A two-step gesture method avoids confusion between strokes and command gestures and allows similar gestures to be used for different functions within the same and different contexts. The system infers from customary user writing conventions that certain relationships of data are to be preserved and maintains the relationships, subject to user override, during editing. The display document is formatted to contain both lined areas of script, text and imbedded drawings that can be edited, including word wrapping, and adjoining unlined drawing areas that remain unaffected by editing of lined area contents.
