System having printed interactive form and sensing device

Abstract

A system for computer software interaction is provided which has a printed form and sensing device. The form has information related to an interactive element coincidentally printed with coded tags. Each tag encodes data on the interactive element and an orientation and position of that tag on the form. The sensing device has an image sensor for capturing images of the tags when the sensing device is used to interact with the interactive element, and a processor. The processor determines the orientations and positions of the tags within the captured images which corresponds to the printed orientations and positions, decodes the data encoded by the captured tags at the determined orientations and positions, and sends indicating data indicative of the decoded data and the determined orientations and positions to a computer system for interpretation of the interaction.

1 . A system for computer software interaction, the system comprising:
 a printed form having information related to an interactive element coincidentally printed with coded tags, each tag encoding data on the interactive element and an orientation and position of that tag on the form; and   a sensing device having an image sensor for capturing images of the tags when the sensing device is used to interact with the interactive element, and a processor for:
 determining the orientations and positions of the tags within the captured images which corresponds to the printed orientations and positions of the tags; 
 decoding the data encoded by the captured tags at the determined orientations and positions; 
 sending indicating data indicative of the decoded data and the determined orientations and positions to a computer system for interpretation of the interaction. 
   
     
     
         2 . A system according to  claim 1 , comprising a relay device for receiving the indicating data from the sensing device and transferring the received indicating data to the computer system. 
     
     
         3 . A system according to  claim 1 , wherein the relay device is a printer. 
     
     
         4 . A system according to  claim 3 , wherein the printer is configured to print the form with said information and coded tags.
