Information Management in an Electronic Pen Arrangement

An electronic pen (101) implements a method for information management, which controls association of information related to different position areas (104', 105A', 105B') on a reference surface (106). The reference surface comprises a plurality of individually addressable position pages (105A', 105B'). The pen has a position detector for detecting positions on the reference surface, each position being associated with a recording time. The pen also has a memory (108) for holding definition data which defines at least one selection area (104') on the reference surface. A position processor in the pen maps the detected positions against the definition data. When the position processor identifies that a detected position falls within the selection area (104'), it selects at least one of the position pages (105A', 105B') based on further detected positions and according to a temporal selection criterion. The criterion typically tells the processor what further positions to analyze and how to analyze them to select the position page(s). The selection area (104') may be associated with a predetermined action to be taken by the position processor with respect to the selected position page (105A', 105B'), for example associating a time-stamped data item with the selected position page (105A', 105B') and/or deriving such a data item.
