Patent ID: 8322607

Claim:
A method of controlling a computer system by an optical sensing device, said method comprising the steps of: receiving a nib force on a nib of said optical sensing device upon said nib of said optical sensing device being pressed against a substrate; effecting a mode change between a cursor control mode and a hyperlinking mode upon said nib force actuating a nib switch coupled to said nib of said optical sensing device; imaging optically coded data printed on the substrate, said coded data being indicative of a region identity associated with the substrate and of a plurality of coordinate locations on the substrate; generating cursor control data using the optically imaged coded data when said optical sensing device is in said cursor control mode; generating interaction data using the imaged coded data when said optical sensing device is in said hyperlinking mode, said interaction data being indicative of the region identity and of at least one coordinate position of the optical sensing device relative to the substrate; and communicating said cursor control data or said interaction data to said computer system, wherein the cursor control data initiates a cursor control response in said computer system and the interaction data initiates a hyperlinking response in said computer system.
