Abstract

Improved data entry for handwriting entry computer systems, including "delayed translation" of written strokes, is provided. After a user has entered data into a handwriting entry computer system, the writing is associated with a target field or object. In one embodiment of the invention, a translation of the entered data is performed, and the untranslated "ink" is displayed. At a later time, if desired, the user can elect to display the translated text. If there are errors or mistranslations, the user can make corrections or revert back to the ink. In another embodiment, a user enters data into the computer system. A translation of the data is performed by a background process. If any of the characters cannot be translated, the original ink is displayed. If all of the characters are translated, the resultant word is compared to a dictionary of words, numbers and symbols. If the resultant translated word does not match a dictionary entry, the original ink is displayed. If there is a match, the translated text is displayed. In another embodiment, the user can selectably choose between translated text and the original ink on a field by field basis.

a mode selector for selecting said display mode; and

memory for retaining a respective block of said data in said original ink form whenever said respective block of said data is displayed in said second display mode.

2. The device of claim 1 wherein said display comprises a display of a computer system.

3. The device of claim 1 wherein said display is a pen sensitive display of a computer system.

4. The device of claim 1 wherein said data entry device comprises a pen.

5. The device of claim 1 wherein said data is comprised of one or more strokes.

6. The device of claim 5 wherein said translator comprises a generator for generating machine readable characters from said strokes.

7. The device of claim 6 wherein said machine readable characters comprise Unicode characters.

8. The device of claim 6 wherein said machine readable characters comprise ASCII characters.

9. The device of claim 1 wherein said mode selector determines said display mode by a user input.

10. The device of claim 1 wherein said memory retains a respective block of said data in said translated form whenever said respective block of said data is displayed in said first display mode.

11. The device of claim 1 further comprising an error detecting means for detecting errors in said translated form of a respective block of said data said errors arising from one of (a) the device'"'"'s inability to translate the original ink form of said respective block of said data and (b) the device'"'"'s inability to match said translated form of said respective block of said data to data in a dictionary.

12. The device of claim 11, wherein said mode selector comprises:

a mode decider for causing said display to display a respective block of said data in said second display mode when said respective block of said data contains no errors and for causing said display to display said respective block of said data in said first mode when said respective block of said data contains errors.

13. The device of claim 1 further comprising:

identifying means for identifying said original ink form of said respective block of said data;

targeting means for identifying a target field of said original ink form of said respective block of said data.

14. The device of claim 13 wherein, when there is a boundary of said original ink form of said respective block of said data, and a boundary of each of said plurality of fields, said targeting means identifies said target field of said original ink form of said respective block of said data by comparing said boundary of said original ink form of said respective block of said data with said boundary of each of said plurality of fields, and identifying said target field as one of said plurality of fields whose said boundary is overlapped by at least a predetermined percentage of area of said boundary of said original ink form of said respective block of said data.

15. A method for input of data comprising the steps of:

receiving input of data and displaying said data;

generating a plurality of fields, each field for receiving and being associated with a respective block of said data;

entering a respective block of said data in each of said plurality of fields in an original ink form comprising one or more strokes;

generating a translated form of a respective block of said data from said original ink form of said respective block of said data;

enabling, in each of said fields, said respective block of data associated with said field to be displayed in one of (a) a first display mode where said respective block of said data is in said original ink form and (b) a second display mode where said respective block of said data is in said translated form;

selecting said display mode; and

retaining a respective block of said data in said original ink form whenever said respective block of said data is displayed in said second display mode.

16. The method of claim 15 wherein said step of receiving and displaying said respective block of said data is performed with a display of a computer system.

17. The method of claim 15 wherein said step of receiving and displaying said respective block of said data is performed with a pen-sensing display of a computer system.

18. The method of claim 15 wherein said step of entering said respective block of said data in said original ink form is performed with a pen.

19. The method of claim 15 wherein said step of generating said translated form of said respective block of said data comprises the step of generating machine readable characters from said strokes.

20. The method of claim 19 wherein said machine readable characters comprise Unicode characters.

21. The method of claim 19 wherein said machine readable characters comprise ASCII characters.

22. The method of claim 15 wherein said selection of said display mode is determined by a user input.

23. The method of claim 15 further comprising the step of retaining a respective block of said data in said translated form whenever said respective block of said data is displayed in said first display mode.

24. The method of claim 15 further comprising the step of detecting errors in said translated form of said respective block of said data, said errors arising from one of (a) inability to translate the original ink form of said respective block of said data and (b) inability to match said translated form of said respective block of said data to data in a dictionary.

25. The method of claim 24 further comprising the step of:

displaying a respective block of said data in said second display mode when said respective block of said data contains no errors and displaying said respective block of said data in said first mode when said respective block of said data contains errors.
