Abstract
A method of enabling a user to instruct a computer system to perform an operation via an interface surface and a sensing device. The interface surface includes an interface, the interface including visible graphical information and substantially invisible coded data. When the sensing device is placed by the user into an operative position relative to the interface surface to designate at least some of the graphical information, it senses indicating data indicative of the operation using at least some of the coded data. The graphical information designated is at least partially indicative, to the user, of the operation. The operation indicated by the indicating data is then performed in the computer system.
Claims28
A method of enabling a user to instruct a computer system to perform an operation via:
- an interface surface including an interface, the interface including visible graphical information and substantially invisible coded data;
- and
- a 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 surface;
- and
- (b) a processor adapted to:
- (i) identify at least some of the coded data from one or more of the captured images;
- (ii) determine an orientation, within the captured images, of at least some of the coded data;
- (iii) decode at least some of the coded data;
- and
- (iv) generate indicating data indicative of the operation, using at least some of the decoded coded data;
- the method including the steps of, in the computer system:
- receiving the indicating data from the sensing device;
- and
- performing the operation indicated by the indicating data;
- wherein the graphical information designated by the user is at least partially indicative, to the user, of the operation.
An interface system for enabling a user to instruct a computer system to perform an operation via:

- and
- a 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 surface;
- and
- (b) a processor adapted to:
- (i) identify at least some of the coded data from one or more of the captured images;
- (ii) determine an orientation, within the captured images, of at least some of the coded data;
- (iii) decode at least some of the coded data;
- and
- (iv) generate indicating data indicative of the operation, using at least some of the decoded coded data;
- the computer system being configured to:
- receive the indicating data from the sensing device;
- and
- perform the operation indicated by the indicating data;
- wherein the graphical information designated by the user is at least partially indicative, to the user, of the operation.
