Abstract

A forms-based computer interface and method captures and interprets handwriting, pen movements, and other manual graphical-type user input for use in computerized applications and databases. An embodiment employs a portable Input and Control Device, a writing implement, and a host computing device that together capture, interpret, utilize, and store the handwriting, marks, and other pen movements of a user on and around predefined and identified forms. The Input and Control Device comprises a device for holding the predefined and identified forms and an e-clipboard for docking the holding device, capturing user input, and transmitting it to the host computing device for processing. Form, field, and user-specific handwriting and mark recognition are used in the interpretation of user input. An edit utility permits review and editing of the captured and interpreted input, permitting correction of capture and interpretation errors.

Claims

1. A method for user-computer interaction, comprising the steps of:

detecting pen-based user input onto at least one identified form, each identified form having a known structure with at least one predefined input field, the step of detecting including detecting an input location relative to the structure of the identified form;

capturing the detected user input to obtain an input content;

classifying the detected and captured input to obtain an input type; and

based on the input type, performing at least one of the steps of;

executing a command;

providing an information display;

performing mark recognition on the captured input to obtain interpreted input; and

performing handwriting recognition on the captured input to obtain interpreted input.

2. The method of claim 1, wherein the step of classifying utilizes the location of the detected input.

3. The method of claim 2, wherein the step of classifying further utilizes the content of the detected input.

4. The method of claim 1, further comprising the step of:

if interpreted input has been obtained, performing at least one of the steps of;

storing the interpreted input in a database;

supplying the interpreted input to an application program; and

displaying the interpreted input.

5. The method of claim 4, further comprising the step of providing a facility for editing the interpreted input.

6. The method of claim 1, further comprising the step of providing a facility for definition of a new identified form.

7. The method of claim 1, wherein at least one predefined form input field is associated with a limited set of valid input content.

8. The method of claim 7, further comprising the step of rejecting captured input at the location of a predefined form input field that is not valid input content for that predefined form input field.

9. The method of claim 1, further comprising the step of detecting which identified form is being used from among a set of possible identified forms.

10. A method for automatically entering the content of pen-based data into a computer-based application, comprising the steps of:

detecting the location of a pen-based data entry on at least one defined form, each defined form having a known location structure and at least one input field within that known location structure;

capturing the pen-based data entry to obtain an entry content;

based on the detected entry location, identifying the input field at that location;

based on the identified input field, performing content recognition on the entry content to obtain an interpreted entry; and

supplying the interpreted entry to the computer-based application.

11. The method of claim 10, further comprising the step of displaying the interpreted entry to a user for verification.

12. The method of claim 11, further comprising the step of permitting user modification of the interpreted entry.

13. The method of claim 10, further comprising the step of the step of detecting which defined form is being used from among a set of possible defined forms.

14. The method of claim 10, further comprising the step of permitting user definition of a new defined form.

15. The method of claim 10, wherein at least one form input field is associated with a limited set of valid entry content.

16. The method of claim 15, further comprising the step of rejecting entry content at a form input field that is not valid entry content for that form input field.

17. A forms-based computer interface, comprising:

a writing implement, the location and content of an entry made by the writing implement being detectable and capturable by automatic means;

an input and control device, comprising;

a writing surface, the writing surface being configured to hold at least one form requiring data input;

at least one location detection device for detecting the location on the form of at least one entry made by the writing input; and

at least one content capture device for capturing the content of the detected entry; and

an input processing system, the input processing system comprising;

a facility for receiving the location and content of the captured entry; and

a facility for recognizing and interpreting the content of the captured entry, based on the entry location, in order to obtain an interpreted entry.

18. The interface of claim 17, wherein the input processing system resides on the input and control device.

19. The interface of claim 17, wherein the input processing system resides on a host computer and the input and control device further comprises a communications device for communicating the detected and captured entry to the host computer for processing in the input processing system.

20. The interface of claim 17, wherein the input processing system further comprises a facility for editing of an interpreted entry.
