Abstract

Handwritten/input stroke data is compared with a gesture dictionary. If the data coincides with a specific gesture, it is checked whether the gesture is completed, and the stroke data is stored. After the meaning of the gesture command is analyzed by using the gesture dictionary, an image stroke data group which does not coincide with any gesture, and an icon group replacing stroke data which coincides with a gesture appears on the display screen. In this state, when the user taps icons having functions as gestures he/she wants to execute, the corresponding gesture commands are executed.

Claims

1. An information processing apparatus capable of processing handwritten information, comprising:

means for storing gesture strokes and corresponding icons indicating commands specified by corresponding gesture strokes;

means for inputting handwritten stroke data;

recognition means for recognizing that a stroke included in the handwritten stroke data is identical to one of the gesture strokes;

means for displaying a stored icon corresponding to the recognized gesture stroke at a position where the recognized gesture stroke was input on a display screen;

judging means for judging the presence or absence of a selection of the displayed icon, at the position where the icon is displayed; and

selection means for selecting, in accordance with the judgment, to execute a command specified by the displayed icon.

2. The apparatus according to claim 1, further comprising means for performing re-display processing for the handwritten stroke data,

wherein said selection means performs a selecting operation to execute the command specified by the recognized gesture stroke in a case that said judging means judges the presence of a selection of the corresponding icon, and

wherein said means for performing re-display processing performs re-display processing in a case that said judging means judges the absence of a selection of the corresponding icon.

3. The apparatus according to claim 2, wherein re-display processing for the handwritten stroke data is performed on the basis of a predetermined state change.

4. The apparatus according to claim 3, wherein the predetermined state change includes at least a state chance in which a selection is not made for a predetermined period of time, the handwritten stroke data is transferred to an application, a file is formed, or a printing operation occurs.

5. The apparatus according to claim 4, wherein the command specified by the gesture stroke is executed with respect to all the displayed icons when a selection is not made for said predetermined period of time.

6. The apparatus according to claim 1, wherein a predetermined symbol representing the handwritten stroke data, which can be identified as the command specified by the recognized gesture stroke, is attached to the icon.

7. An information processing method capable of processing handwritten information, comprising the steps of:

recognizing a stroke identical to one of a plurality of stored gesture strokes, the gesture strokes corresponding to icons indicating commands specified by corresponding gesture strokes, the recognized stroke included in handwritten stroke data;

displaying an icon corresponding to the recognized gesture stroke at a position where the recognized gesture stroke was input on a display screen;

judging the presence or absence of a selection of the displayed icon at the position where the icon is displayed; and

selecting, in accordance with the judgment, to execute a command specified by the displayed icon.

8. The method according to claim 7, further comprising the step of performing re-display processing for the handwritten stroke data,

wherein, in said selection step, a selecting operation is performed to execute the command specified by the recognized gesture stroke in a case that, in said judging step, the presence of a selection of the icon is judged, and

wherein re-display processing is performed in a case that, in said judging step, the absence of a selection of the icon is judged.

9. The method according to claim 8, wherein re-display processing for the handwritten stroke data is performed on the basis of a predetermined state change.

10. The method according to claim 9, wherein the predetermined state change includes at least a state change in which a selection is not made for a predetermined period of time, the handwritten stroke data is transferred to an application, a predetermined file is formed, or a printing operation occurs.

11. The method according to claim 10, wherein the command specified by the recognized gesture stroke is executed with respect to all the displayed icons when a selection is not made for said predetermined period of time.

12. The method according to claim 7, wherein a predetermined symbol representing the handwritten stroke data, which can be identified as the command specified by the recognized gesture stroke is attached to the icon.

13. An information processing apparatus capable of processing handwritten information, comprising:

means for storing stroke data and corresponding icons indicating commands specified by corresponding stroke data;

means for inputting handwritten image data;

recognition means for recognizing a meaning of a stroke included in the handwritten image data which is identical to one of the stored stroke data;

means for displaying a corresponding stored icon corresponding to said recognized meaning at a position where the stroke was input on a display screen;

judging means for judging the presence or absence of a selection of the displayed icon at the position where the icon is displayed; and

selection means for selecting, in accordance with the judgment, to make the displayed icon active.

14. The apparatus according to claim 13, further comprising means for performing re-display processing for the handwritten image data,

wherein said selection means performs a selecting operation to execute an operation having the meaning corresponding to said icon in a case that said judging means judges the presence of a selection of the icon, and

wherein said means for performing re-display processing performs re-display processing in a case that said judging means judges the absence of a selection of the predetermined icon.

15. The apparatus according to claim 14, wherein re-display processing for the handwritten image data is performed on the basis of a predetermined state change.

16. The apparatus according to claim 15, wherein the predetermined state change includes at least a state change in which a selection is not made for a predetermined period of time, the handwritten image data is transferred to an application, a file is formed, or a printing operation occurs.

17. The apparatus according to claim 16, wherein an operation having the meaning corresponding to said icon is executed with respect to all displayed icons when a selection is not made for said predetermined period of time.

18. An information processing method capable of processing handwritten information, comprising the steps of:

recognizing a stroke identical to one of a plurality of stored strokes, the strokes corresponding to stored icons indicating commands specified by the strokes, the recognized stroke included in handwritten image data;

displaying a corresponding stored icon corresponding to a meaning of said recognized stroke at a position where the recognized stroke was input on a display screen;

judging the presence or absence of a selection of the displayed icon at the position where the icon is displayed; and

selecting, in accordance with the judgment, to make displayed icon active.

19. The method according to claim 18, further comprising the step of performing re-display processing for the handwritten image data,

wherein, in said selection step, a selecting operation having the meaning corresponding to said icon is performed in a case that, said judging step, the presence of a selection of the icon is judged, and

wherein re-display processing is performed in a case that, in said judging step, the absence of a selection of the icon is judged.

20. The method according to claim 19, wherein the restoration to the re-display processing for the handwritten image data is performed on the basis of a predetermined state change.

21. The method according to claim 20, wherein the predetermined state change includes at least a state change in which a selection is not made for a predetermined period of time, the handwritten data is transferred to an application, a predetermined file is formed, or a printing operation occurs.

22. The method according to claim 21, wherein an operation having the meaning corresponding to said icon is not made for said predetermined period of time.

23. A computer-readable storage medium holding program codes for processing handwritten information, comprising:
