The present invention relates to a jotting implement that infers hand-jotted information from a jotting surface. The hand-jotted information is any information marked on the jotting surface as a result of writing, jotting, drawing, sketching, or in any other manner of marking or depositing marks on the jotting surface. Hand-jotted information is also information traced on t he jotting surface without leaving any markings thereon or otherwise produced b y the motions executed by the jotting implement with respect to the jotting surface while in contact with the jotting surface. The jotting implement has a nib for jotting and an arrangement for determining when the nib is jotting o n the jotting surface. Further, the implement has an optical unit for viewing the jotting surface. The implement also has a processing unit for receiving optical data of said jotting surface from the optical unit and determining from it the physical coordinates of the nib with respect to at least one corner of the jotting surface and at least one edge of the jotting surface and/or other landmarks or optically recognizable features on the jotting surface.
