Abstract

A pen or stylus-operated graphical user interface for a computer or computing device, which includes a sensing surface having an area corresponding to a data input field, the data input field being conditioned for hand entering and editing of graphical input symbols, and handwriting recognition software operative to analyze the graphical input symbols and superimposing a display field of character data corresponding to the graphical input symbols on the data input field.

Claims

1. A pen or stylus operable system for a computer, comprising:

(a) a graphical user interface coupled to said computer and having a sensing surface said sensing surface having an area corresponding to a data input field, said sensing surface controlled by said graphical user interface and having means for hand entering and editing of graphical input symbols;

(c) handwriting recognition software on said computer operative to analyze said graphical input symbols one after another without interruption or delay and to automatically superimpose on and replace said graphical input symbols with a display field of character data corresponding to said graphical input symbols on said data input field.

2. An interface according to claim 1, wherein said sensing surface is display surface.

3. An interface according to claim 1, wherein said sensing surface is a tablet separate from a display surface.

4. An interface according to claim 1, wherein said handwriting recognition software also initiates an action based upon said graphical input symbol.

5. An interface according to claim 1, wherein said handwriting recognition software initiates an editing mode when said pen or stylus contacts said sensing surface without moving for a predetermined minimum amount of time.

6. An interface according to claim 5, wherein symbol recognition of handwritten input is a default mode and editing mode is initiated with a timeout.

7. An interface according to claim 5, wherein movement of said pen, in predefined ways, while being held in continuous contact with the sensing surface, without being removed from said data input field, causes corresponding editing functions to be effected.

8. An interface according to claim 7, wherein said character data is corrected and edited in said editing mode without moving a cursor for said pen or stylus outside said data input field of said sensing surface.

9. Apparatus for combining data entry of handwritten symbols with displayed character data in a pen or stylus-operable graphical user interface for a computer or computing device, comprising:

(a) means for recording and displaying handwritten graphical input symbols as they are entered on a data input field of a display surface; and

(b) user recognition software for analyzing said graphical input symbols one after another continuously without interruption or delay and automatically superimposing on and retlacing said graphical input symbols with display field character data corresponding to said graphical input symbols.

10. Apparatus according to claim 9, wherein said means for recording is a sensing surface operative to receive and record the graphical input symbols.

11. Apparatus according to claim 10, wherein said means for displaying is said display surface.

12. Apparatus according to claim 10, wherein said sensing surface is at least part of said display surface.

13. Apparatus according to claim 9, wherein said handwriting recognition software also initiates an action based upon said graphical input symbol.

14. Apparatus according to claim 9, wherein said handwriting recognition software initiates an editing mode when said pen or stylus contacts said display surface for a predetermined minimum time without moving.

15. Apparatus according to claim 14, wherein movement of said pen, without being removed from said data input field, in predefined ways, while held in continuous contact with the sensing surface causes corresponding editing functions to be effected.

16. Apparatus according to claim 15, wherein character data is corrected and edited in said editing mode without moving a cursor for said pen or stylus outside said data input field.
