Abstract:
1. A method of recognising digital ink input by a user into a computer-based digital ink recognition system, the user interacting with a paper-based document, the paper-based document having disposed therein or thereon coded data indicative of a particular field of the paper-based document and of at least one reference point of the paper-based document, the method including the steps of: receiving in a server, indicating data from a sensing device, operated by the user, regarding the identity of the paper-based document and at least one of a position and a movement of the sensing device relative to the paper-based document; processing the indicating data using a recognizer residing on the server to produce intermediate format data; and, transmitting the intermediate format data to an application; wherein, the application decodes the intermediate format data into computer-readable format data using context information associated with the paper-based document; further wherein, the sensing device comprises: (a) an image sensor adapted to capture images of at least some of the coded data when the sensing device is placed in an operative position relative to the paper-based document; and (b) a processor adapted to: (i) identify at least some of the coded data from one or more of the captured images; (ii) decode at least some of the coded data; and (iii) generate the indicating data using at least some of the decoded coded data.
