Patent ID: 8009151

Claim:
A system for enabling user interaction with computer software, the system including a printer for: receiving print data; printing a form, using the print data, by printing: information related to at least one text field; and, coded data at least partially indicative of the at least one text field, the coded data being coincident with the information; receiving indicating data from a sensing device, the sensing device, when moved in an operative position relative to the at least one text field, sensing the coincident coded data and generating the indicating data using the sensed coded data, the indicating data being at least partially indicative of movement of the sensing device relative to the at least one text field; and transferring the indicating data to a computer system to allow the interaction to be interpreted, wherein the system includes the sensing device, the sensing device comprising: (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 interface surface; and (b) a processor adapted to: (i) identify at least some of the coded data from at least one of the captured images; (ii) determine an orientation and position, within at least one of the captured images, of at least some of the coded data; (iii) decode at least some of the coded data; and (iv) generate the indicating data using at least some of the decoded coded data and the determined orientation and position.
