Method and system for enabling user instruction through interaction with interface surface
First Claim
1. A method of enabling a user to instruct a computer system to perform an operation by interacting with graphical information and coded data printed on a first interface surface using a sensing device which generates indicating data indicative of the operation by sensing the coded data, the method comprising the steps of:
- receiving, in the computer system, the indicating data from the sensing device;
performing, in the computer system, the operation indicated by the indicating data; and
printing, in response to performing the operation, a second interface surface with graphical information relating to the performed operation and coded data, the coded data comprising a plurality of marks positioned relative to a predetermined pattern, the predetermined pattern having a rotationally invariant structure and an orientation target structure for allowing rotation of the coded data relative to the sensing device to be determined.

Abstract
There is provided a method of, and interface system for, enabling a user to instruct a computer system to perform an operation by interacting with graphical information and coded data printed on a first interface surface using a sensing device which generates indicating data indicative of the operation by sensing the coded data. In the method, and interface system, the computer system receives the indicating data from the sensing device, the computer system performs the operation indicated by the indicating data, and in response to performing the operation, a second interface surface is printed with graphical information relating to the performed operation and coded data.
