Patent ID: 7834852

Claim:
A system for enabling user interaction with computer software, the system including a computer system for: generating print data; transferring the print data to a printer, the printer being responsive to the print data to print a form by printing: information related to at least one interactive element; and, coded data at least partially indicative of the at least one interactive element, the coded data being coincident with the information; receiving indicating data from a sensing device, the sensing device, when placed in an operative position relative to the information, sensing the coincident coded data and generating the indicating data using the sensed coded data, the indicating data being at least partially indicative of the at least one interactive element; identifying, using the indicating data, the at least one interactive element; and, performing an action associated with the at least one interactive element, 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.
