Abstract
An electronic pen for recording of handwritten or hand-drawn information has a control unit and a memory. The control unit registers pen movements across at least one base, stores a plurality of digital pen strokes in the memory as a function of said movements, and supplies a set of the digital pen strokes for processing. The digital pen strokes include a first type, which is processed as graphical information constituting the information to be recorded, and a second type, which is processed as instructions for the processing of digital pen strokes of the first type. The electronic pen may detect a current working session of the pen. The control unit indicates, for the processing of the set of digital pen strokes, the working session during which the respective digital pen strokes have been input.
