Abstract

A method of interpreting handwritten data inputted on a printed form using an optically sensing pen. The form has a plurality of different form fields for the handwritten data input. The form also includes a plurality of printed tags, each tag encoding a location on the form. The method comprising performing, in a computer system, the steps of: (a) receiving, from the pen, digital ink representing handwritten data input of the pen relative to the form, the digital ink being generated in said pen by sensing a plurality of tags during handwritten input in one of the form fields; (b) identifying, using the digital ink and a description of the form stored in the computer system, the form field in which handwritten data has been inputted; (c) identifying, in the computer system, a set of predetermined text values associated with the identified form field; and (d) interpreting the handwritten data by decoding the digital ink and converting the decoded digital ink into computer text. The computer text is selected only from the set of predetermined text values identified in step (c).

Claims

1. A method of interpreting handwritten data inputted on a printed form using an optically sensing pen, said form having a plurality of different form fields for said handwritten data input, said form including a plurality of printed tags, each tag encoding a location on the form,

said method comprising performing, in a computer system, the steps of:

(a) receiving, from the pen, digital ink representing handwritten data input of the pen in one of said form fields, said digital ink being generated in said pen by sensing a plurality of tags during said handwritten input in said form field;

(b) identifying, using the digital ink and a description of the form stored in the computer system, the form field in which handwritten data has been inputted;

(c) identifying, in the computer system, a set of predetermined text values associated with the identified form field; and

(d) interpreting the handwritten data by decoding the digital ink and converting the decoded digital ink into computer text,

wherein the computer text is selected only from the set of predetermined text values identified in step (c).

2. The method as claimed in claim 1, wherein the field is a name field and the set of predetermined text values comprises a plurality of names.

3. The method as claimed in claim 1, wherein the field is an address field and the set of predetermined text values comprises a plurality of known addresses.

4. The method as claimed in claim 1, wherein the field is a telephone number field and the set of predetermined text values comprises numerals only.

5. The method as claimed in claim 1, wherein the field is a credit card number field, and the set of predetermined text values comprises numerals only.

6. The method of claim 1, wherein said form is an order form.

7. The method of claim 6, wherein said form includes at least one button for submission of an order.

8. The method of claim 7, further comprising the steps of:

receiving, from the pen, position data indicative of selection of the button; and

initiating an order represented by the handwritten data input on the form.

9. The method of claim 1, wherein each tag identifies a form identity.

10. The method of claim 1, wherein said digital ink includes the form identity and said description of the form is identified using the form identity.
