Abstract

In a character-figure editing apparatus, a user can correctly select a desired character or figure from a plurality of characters and figures on a display section. The user inputs the character, the figure, and the editing operation by handwriting. A decision section identifies the handwritten information as one of the character, the figure and the editing operation. A memory section stores the character information and the figure information identified by the decision section. A display section displays the input handwriting information, the character and the figure stored in the memory section. The input handwritten information is temporarily stored as a series of coordinates in order. The decision section selects a corresponding character or figure in accordance with the input handwritten information when the handwritten information is identified as the editing operation. Then an editing section edits the character or the figure in accordance with the editing operation.

Claims

1. Character-figure editing apparatus, comprising:

display means for displaying a plurality of characters or figures, each of which was previously inputted by a user as a first handwritten information;

memory means for storing the first handwritten information of each of the plurality of characters or figures as attribute information and a first series of coordinates inputted in an order, the attribute information including characteristics of the character or the figure, and the first series of coordinates including (X,Y) coordinates, a distance and a slope between a pen and a tablet;

input means for inputting a second handwritten information by the user tracing on at least one of the plurality of characters or figures displayed by said display means, the input means comprising the pen and the tablet for the user to handwrite on the tablet to draw the plurality of characters or figures, or an editing operation;

storing means for temporarily storing the second handwritten information inputted by said input means as a second series of coordinates inputted in an order, the second series of coordinates including (X, Y) coordinates, switch on/off information, a distance and a slope between the pen and the tablet;

decision means for comparing the second handwritten information stored in said storing means with the first handwritten information stored in said memory means, and for selecting the character or the figure represented in said memory means by the first handwritten information that coincides with the second handwritten information in said storing means; and

editing means for editing the selected character or figure by the editing operation inputted by the user.

2. The character-figure editing apparatus according to claim 1,

wherein said decision means includes an editing operation memory means for storing a plurality of handwritten patterns and associated editing operations for use in identifying the inputted handwritten information as one of the associated editing operations.

3. The character-figure editing apparatus according to claim 1,

wherein said input means inputs a handwritten information by the user as the editing operation for the selected character or figure,

and said display means displays the handwritten information of the editing operation inputted by said input means.

4. The character-figure editing apparatus according to claim 3,

wherein said decision means includes means for identifying a kind of editing operation of the inputted handwritten information after the handwritten information is selected as coinciding with the character or figure information, in accordance with the handwritten patterns stored in said editing operation memory means.

5. The character-figure editing apparatus according to claim 4,

wherein said decision means identifies the handwritten information as a newly inputted character or figure when the handwritten information does not coincide with the character or figure information in said memory means.

6. The character-figure editing apparatus according to claim 1,

wherein said display means highlights the display of the character or figure selected by said decision means in comparison with the other characters and figures displayed.

7. The character-figure editing apparatus according to claim 6,

wherein said display means displays a plurality of the characters or figures one by one which are selected by said decision means when the handwritten information corresponds to a plurality of the character or figure information in said memory means.

8. Character-figure editing method, comprising the steps of:

displaying a plurality of characters or figures, each of which was previously inputted by a user as a first handwritten information;

storing the first handwritten information of each of the plurality of characters or figures as attribute information and a first series of coordinates inputted in an order, the attribute information including characteristics of the character or the figure, and the first series of coordinates including (X, Y) coordinates, a distance and a slope between a pen and a tablet;

inputting a second handwritten information through an input means by the user tracing on at least one of the plurality of characters or figures displayed at the displaying step, the input means comprising the pen and the tablet for the user to handwrite on the tablet to draw the plurality of characters or figures, or an editing operation;

storing the second handwritten information inputted at the inputting step as a second series of coordinates inputted in an order, the second series of coordinates including (X, Y) coordinates, switch on/off information, a distance and a slope between the pen and the tablet;

comparing the first handwritten information with the second handwritten information;

selecting one of the plurality of characters or figures stored at the first storing step by the first handwritten information that coincides with the second handwritten information stored at the second storing step; and

editing the one of the plurality of characters or figures selected at the selecting step by the editing operation inputted by the user.

9. A computer readable memory containing computer-readable instructions, comprising:

instruction means for causing a computer to display a plurality of characters or figures, each of which was previously inputted by a user as a first handwritten information;

instruction means for causing the computer to store the first handwritten information of each of the plurality of characters or figures as attribute information and a first series of coordinates inputted in an order, the attribute information including characteristics of the character or the figure, and the first series of coordinates including (X, Y) coordinates, a distance and a slope between a pen and a tablet;

instruction means for causing the computer to input a second handwritten information through an input means by the user tracing on at least one of the plurality of characters or figures displayed, the input means comprising the pen and the tablet for the user to handwrite on the tablet to draw the plurality of characters or figures, or an editing operation;

instruction means for causing the computer to store the second handwritten information of the user tracing as a second series of coordinates inputted in an order the second series of coordinates including (X, Y) coordinates, switch on/off information, a distance and a slope between the pen and the tablet;

instruction means for causing the computer to compare the second handwritten information of the user tracing with the first handwritten information of each of the plurality of characters or figures;

instruction means for causing the computer to select the character or the figure from the plurality of characters or figures by the first handwritten information that coincides with the second handwritten information of the user tracing; and

instruction means for causing the computer to edit the selected character or figure by the editing operation inputted by the user.
