Abstract

A method and apparatus for manipulating inked objects in a computer system includes the steps of displaying a first recognized object on a computer screen and displaying a first ink object on the screen which was previously recognized as the first recognized object. The first ink object is edited to create a second ink object, and the second ink object is recognized as a second recognized object. The first recognized object is then replaced with the second recognized object. The method also preferably includes a step of selecting the first recognized object, and the first ink object is displayed in response to the selection step. A preferred method of selecting the first recognized object is to move a stylus within a predetermined distance or bounding box of the first recognized object. Editing the first ink object preferably includes adding or deleting a portion of the ink object, inserting a space between characters of the ink object, replacing a portion of the ink object, and adding new ink to the ink object. Alternate embodiments include moving the recognized object to different locations on the screen in relation to the first ink object, and determining in advance if the path of the stylus in moving toward the bounding box of the recognized object. The method and apparatus of the present invention permits convenient and quick manipulation of inked objects and correction of recognized objects displayed on a pen computer system.

Claims

1. A method for editing a recognized object on a computer screen comprising:

displaying a first recognized object on a computer screen;

displaying a first ink object on said computer screen which was previously recognized as said first recognized object, wherein said first recognized object and said first ink object are displayed concurrently;

editing said first ink object to create a second ink object;

recognizing said second ink object as a second recognized object;

replacing said first recognized object with said second recognized object.

2. A method as recited in claim 1 further comprising the step of moving said first recognized object on said computer screen when displaying said first ink object.

3. A method as recited in claim 1 further comprising a step of selecting said first recognized object for editing and wherein said step of displaying said first ink object is accomplished in response to said step of selecting said first recognized object.

4. A method as recited in claim 3 wherein said step of selecting said first recognized object is accomplished by moving a pointing means within a predetermined distance of said first recognized object.

5. A method as recited in claim 1 wherein said step of editing said first ink object is accomplished with a pointing means.

6. A method as recited in claim 5 wherein said step of editing said first ink object includes deleting at least a portion of said first ink object.

7. A method as recited in claim 5 wherein said first ink object comprises a plurality of characters, and wherein said step of deleting includes entering a gesture to delete at least one character.

8. A method as recited in claim 5 wherein said first ink object comprises a plurality of characters, and wherein said step of editing said first ink object includes inserting space between two adjacent characters.

9. A method as recited in claim 8 wherein said step of inserting space between two adjacent characters is accomplished by entering a space gesture.

10. A method as recited in claim 5 wherein said step of editing said first ink object includes entering new ink over at least a portion of said first ink object to replace said at least a portion of said first ink object with said new ink.

11. A method as recited in claim 12 wherein said step of editing includes entering new ink, wherein said second ink object includes said first ink object and said new ink.

12. A method as recited in claim 5 wherein said step of recognizing said second ink object is accomplished after a delimiter occurs indicating said editing step is complete.

13. A method as recited in claim 12 wherein said delimiter includes a predetermined period of time elapsing after said first ink object is edited.

14. A method as recited in claim 12 wherein said delimiter includes moving a pointing means a predetermined distance from said first ink object.

15. A method as recited in claim 1 wherein said step of replacing said first ink object with said second ink object includes displaying said second ink object in place of said first ink object.

16. A method as recited in claim 1 further comprising displaying said second recognized object in place of said first recognized object.

17. A method for displaying information in a computer system comprising:

displaying a recognized object on a screen of a computer system;

selecting said recognized object; and

displaying an original ink object at about its original position and in about its original configuration while simultaneously displaying said recognized object, such that said original ink object can be edited.

18. A method as recited in claim 17 wherein said step of selecting is accomplished with a pointing means.

19. A method as recited in claim 18 wherein said step of selecting said recognized object is accomplished when said pointing means is on said screen and within a predetermined distance of said recognized object within the plane of the screen.

20. A method as recited in claim 19 further comprising a step of editing said ink object to create a new ink object.

21. A method as recited in claim 20 further comprising a step of recognizing said new ink object as a new recognized object.

22. A method as recited in claim 21 further comprising a step of replacing said recognized object with said new recognized object.

23. A method as recited in claim 18 wherein said step of selecting said recognized object is accomplished when said pointing means is proximate to but not touching said screen and within a predetermined distance above said plane of said screen.

24. A method as recited in claim 23 wherein said step of selecting said recognized object includes determining a path of said pointing means.

25. A method as recited in claim 24 wherein said step of selecting said recognized object includes:

collecting a number of points representing said path;

calculating a least squares fit line of said points; and

selecting said recognized object when said fit line points towards said recognized object.

26. A computer system comprising:

digital processing means;

memory means coupled to said digital processing means;

screen means coupled to said digital processing means;

pointer means coupled to said digital processing means for entering an ink object into said memory means;

means for recognizing said ink object entered into said memory means and for displaying a recognized object on said screen means;

means for selecting said recognized object; and

means for displaying said ink object as entered into said memory means on said screen in a substantially unaltered state while simultaneously displaying said recognized object, such that said original ink object can be edited.

27. A computer system as recited in claim 26 wherein said pointer means is selected from the group comprising stylus, mouse, and trackball pointing devices.

28. A computer system as recited in claim 26 wherein said screen means and said pointer means are parts of a pen computer system.

29. A computer system as recited in claim 28 wherein said means for selecting includes means for detecting said pointer means within a predetermined distance of said recognized object.

30. A computer system as recited in claim 28 further comprising means for editing said ink object.

31. A computer system as recited in claim 30 further comprising means for recognizing said edited ink object as a new recognized object.

32. A computer system as recited in claim 31 further comprising means for replacing said recognized object with said new recognized object.
