Abstract

A word processor is provided with a handwriting text processing function. A display displays document and text processing information. A pointing device enters handwritten text processing figures on a display. A memory stores text processing instructions associated with an text processing figure drawn on the screen. A direction in which the pointing device is moved on the screen to draw a figure, a length of the drawn figure on the screen, and/or which of several regions of the display the pointing device is presently pointing to are determined and used to distinguish different text processing functions associated with the same basic handwritten text processing figure. The word processor uses this information to selectively execute different kinds of text processing instructions such as an up-scroll of the screen, a down-scroll of the screen, a display of document head, a display of document tail, a display of underline, a display of line head, an arbitrary cursor movement, and a cursor shift on the same line.

a processor for performing the following steps;

analyzing a document processing function-symbolic figure drawn on the display with the pointing device with one of the stored document processing figures and identifying a corresponding one of the stored document processing figures;

selecting one of the two document processing operations associated with the identified document processing figure based on a determination of a direction in which the pointing device is moved on the display when the document processing figure is drawn and a determination of a length of the drawn document processing figure; and

executing the set of document processing instructions associated with the selected document processing operation.

2. A word processor according to claim 1, wherein the processor detects a sequence of a pen-down position followed by a pen-up position of the pointing device with respect to the display to determine the direction in which the pointing device is being moved while drawing the document processing figure, and when the processor determines that the pointing device is being moved in a downward direction from an upper portion of the display, the processor executes the set of document processing instructions for implementing the up-scroll operation when the length of the drawn figure is less than a predetermined length and the set of document processing instructions for implementing the document head display operation when the length of the drawn figure is greater than the predetermined length.

3. A word processor according to claim 1, wherein the processor detects a sequence of a pen-down position followed by a pen-up position of the pointing device with respect to the display to determine an upward direction in which the pointing device is moved from a lower portion of the display while drawing a figure, the processor executing the set of document processing instructions for implementing the down-scroll operation when the length of the drawn figure is less than a predetermined length and the set of document processing instructions for implementing the document tail display operation when the length of the drawn figure is greater than the predetermined length.

4. A word processor providing handwritten document processing functions, comprising:

a display including a plurality of display regions for displaying a document including text characters in a document display region and document processing information in another display region;

a pointing device for drawing any one of a plurality of document processing figures displayed on the display;

a memory for storing for each document processing figure a set of document processing instructions for implementing a document processing operation associated with that document processing figure, at least some of the document processing figures being associated with two different document processing operations; and

a processor for performing the following steps;

analyzing a document processing figure drawn on the display with the pointing device with one of the stored document processing figures and identifying a corresponding one of the stored document processing figures;

selecting one of the two document processing operations associated with the identified document processing figure based on a direction in which the pointing device is moved on the display when the document processing figure is drawn and a particular one of the display regions in which the document processing figure is drawn; and

executing the set of document processing instructions associated with the selected document processing operation.

5. The word processor according to claim 4, wherein the document processing operations include a display of an underline, a display of a line head, and cursor movement.

6. A word processor according to claim 5, wherein the processor detects a sequence of a pen-down position followed by a pen-up position of the pointing device to determine if the pointing device was moved from a left portion of the display to an upper right portion of the display while drawing a figure and executes the set of document processing instructions for implementing the underline display operation when the drawn figure is included within a document display region and the set of document processing instructions for implementing the line head display operation when the drawn figure is within a guidance display region not included in the document display region.

7. A word processor according to claim 5, wherein the processor detects a sequence of a pen-down position followed by a pen-up position to determine if a figure drawn on the display is approximately a point, and if so, executes the set of document processing instructions for implementing the cursor movement operation to move a position of a displayed cursor to a digit position on a same display line where the cursor is currently located when the pen-down position is located in a scale display region which is not included in the document display region.

8. A word processor according to claim 5, wherein the processor detects a pen-down position of the pointing device on the display in a scale display region different from the document display region, and from that detected pen-down position, calculates a corresponding cursor position in the document display region and causes a cursor to be displayed at that corresponding cursor position.

9. A method for processing a document using handwritten document processing figures comprising the steps of:

displaying a document including text characters in a document display region of a display;

using a pointing device, drawing any one of a plurality of document processing function-symbolic figures and displaying the drawn figure on the display;

storing for each document processing function-symbolic figure a document processing figure and a set of document processing instructions for implementing a document processing operation associated with that document processing figure, at least some of the document processing figures being associated with two different document processing operations and the document processing operations include an up-scroll of the screen, a down-scroll of the screen, a display of a beginning of a document head, and a display of an end of the document;
