Abstract
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, including insertion of a moving space into pre-existing document text and word wrapping. Adjoining drawing areas are unaffected by editing of text data.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
84 words
A computerized method for determining word boundaries from ink strokes entered with a graphical input device on a dynamic document display, the method comprising: entering ink strokes onto the document display; grouping the ink strokes as a script line; ordering the ink strokes in the script line according to the leftmost point of each stroke so that the strokes are ordered from left to right; grouping adjacent sets of ink strokes separated along the script line by a pre-determined amount of space as words.
Claim 2
Dependent Claim
84 words
A computerized method for determining word boundaries from ink strokes entered with a graphical input device on a dynamic document display, the method comprising: entering ink strokes onto the document display; grouping the ink strokes as a script line; ordering the ink strokes in the script line according to the leftmost point of each stroke so that the strokes are ordered from left to right; grouping adjacent sets of ink strokes separated along the script line by a pre-determined amount of space as words.
Claim 3
Dependent Claim
26 words
A method according to claim 1 in which the script line to which an ink stroke belongs is determined by the starting point of the stroke.
Claim 4
Dependent Claim
27 words
A method according to claim 1 in which the script line to which an ink stroke belongs is determined by its proximity to a current input area.
Claim 5
Dependent Claim
29 words
A method according to claim 1 in which an ink stroke is reassigned to an adjacent script line and associated with the ink strokes in said adjacent script line.
Claim 6
Dependent Claim
14 words
A computer-readable medium having computer-executable instructions for performing the method of claim 1 .
Claim 7
Dependent Claim
155 words
A pen-based computer method for a user interactively to edit glyphs on a document display to insert handwritten script using a pen-type input device, the method comprising: forming a series of lines, each having a beginning point and an end point, to define line spaces for writing script; writing N consecutive strokes in one or more of the line spaces; determining a common input line space; establishing the common input line space as the current input line space if: (a) the N strokes are within a user-definable horizontal distance, (b) the N strokes are within a predetermined vertical proximity of the common input line space, and (c) the N strokes are contained within three adjacent line spaces including the common input line space, a preceding line space, and a subsequent line space; associating with the current input line space those of the N consecutive strokes that are not currently residing in the current input line.
Claim 8
Dependent Claim
155 words
A pen-based computer method for a user interactively to edit glyphs on a document display to insert handwritten script using a pen-type input device, the method comprising: forming a series of lines, each having a beginning point and an end point, to define line spaces for writing script; writing N consecutive strokes in one or more of the line spaces; determining a common input line space; establishing the common input line space as the current input line space if: (a) the N strokes are within a user-definable horizontal distance, (b) the N strokes are within a predetermined vertical proximity of the common input line space, and (c) the N strokes are contained within three adjacent line spaces including the common input line space, a preceding line space, and a subsequent line space; associating with the current input line space those of the N consecutive strokes that are not currently residing in the current input line.
Claim 9
Dependent Claim
63 words
A method according to claim 6 wherein the step of determining the common input line space comprises: determining a center of gravity for each of the N strokes; determining for each stroke a resident line wherein the center of gravity of said stroke resides; and establishing the common input line as the line having a user-definable percentage of the N center of gravities.
Claim 10
Dependent Claim
55 words
A method according to claim 6 wherein the step of determining the common input line space comprises: determining a center of gravity for each of the N strokes; determining an average center of gravity from the N center of gravities; establishing the common input line as the line wherein the average center of gravity resides.
Claim 11
Dependent Claim
39 words
A method according to claim 6 including writing M strokes following the N strokes and storing each of the M strokes in the current input line if a portion of each M stroke contacts the current horizontal input area.
Claim 12
Dependent Claim
14 words
A computer-readable medium having computer-executable instructions for performing the method of claim 6 .
Claim 13
Dependent Claim
104 words
A pen-based computer method for a user interactively to edit glyphs on a document display to insert handwritten script using a pen-type input device, the method comprising: forming a series of lines, each having a beginning point and an end point, to define line spaces for writing script; determining a current input line space; determining a current horizontal input area within the current input line; determining vertical and horizontal extents of a stroke; storing the stroke in the current input line if a portion of the stroke contacts the current input line and a portion of the stroke contacts the current horizontal input area.
Claim 14
Dependent Claim
104 words
A pen-based computer method for a user interactively to edit glyphs on a document display to insert handwritten script using a pen-type input device, the method comprising: forming a series of lines, each having a beginning point and an end point, to define line spaces for writing script; determining a current input line space; determining a current horizontal input area within the current input line; determining vertical and horizontal extents of a stroke; storing the stroke in the current input line if a portion of the stroke contacts the current input line and a portion of the stroke contacts the current horizontal input area.
Claim 15
Dependent Claim
53 words
A method according to claim 11 wherein the horizontal input area moves along the current input line as the user writes, the method comprising: identifying the word containing the latest stroke that was entered into the current input line; repositioning the horizontal input area along the current input line relative to said word.

Dependent Claim
14 words
A computer-readable medium having computer-executable instructions for performing the method of claim 11 .
