Abstract

The enhanced feature of this invention is the direction of a pen input on an electronic device to a separate canvas where it can be separately manipulated and processed for use. Temporal and spatial analysis can ensure that each canvas contain pen strokes that spatially belong together such as an individual word composed of multiple strokes for easy manipulation of the word on the screen. Another related enhanced feature of the invention for erasing portions of the inputted writing is the process of generating a new curve with different points than the original curve.

Claims

1. A method to be executed at least in part in a pen input receiving application comprising:

receiving a pen input;

creating a canvas area based on spatial and temporal pen input information; and

inserting the canvas area.

2. The method of claim one wherein said canvas area is a smaller area than the original area that accepts said pen input.

3. The method of claim two wherein the said canvas area encloses a single word.

4. A method to be executed at least in part in a pen and eraser input receiving application on a existing digital pen contour comprising:

receiving an eraser input;

determining the shape of an erasing contour;

identifying new points that did not necessarily exist on the original pen contour based on the erasing input;

modifying an pen contour based on the erasing contour and said new points; and

inserting the new contour or contours.

5. The method of claim four wherein at least one of the new points did not exist on the original pen contour.

6. A computer readable medium capable of storing a program facilitating rendering and electronic pen stroke being intersected by an erasing contour the program comprising the steps of:

receiving an eraser input;

determining the shape of an erasing contour;

identifying new points that did not necessarily exist on the original pen contour based on the erasing input;

modifying an pen contour based on the erasing contour and said new points; and

inserting the new contour or contours.

7. The computer readable medium of claim six wherein at least one of the new points did not exist on the original pen contour.

8. A computer readable medium capable of storing a program facilitating rendering and electronic pen stroke the program comprising the steps of:

receiving a pen input;

creating a canvas area based on spatial and temporal pen input information; and

inserting the canvas area.

9. The computer readable medium of claim eight wherein said canvas area is a smaller area than the original area that accepts said pen input.

10. The computer readable medium of claim nine wherein said canvas area encloses a single word.
