Abstract
A pen-based processor needs to be usable to input and edit script like a text-based computer but retain a resemblance to the user of a pad and pencil. The disclosed system and method implement input, editing and other manipulation of glyphs including handwritten script, ASCII test, bit-mapped images 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 using 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 use of similar gestures 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 lined or unlined areas of glyphs that can be edited, such as by mapping each glyph in the image lines to a machine editable line space including insertion of a moving space i…
