Abstract:
1. A pen system for recording a track of handwritten information created by the pen device, comprising: a handheld pen device comprising an image sensor for optically imaging a position-coding pattern printed on a surface and a processor for recording said handwritten information as digital ink using the imaged position-coding pattern, said digital ink identifying a surface identity; and a memory for storing said digital ink, wherein the memory includes: a first memory unit located in the hand-held pen device; and a second memory unit located in an external data storage device, which memory units are connected in such a way that a transmission of said digital ink is caused to occur automatically from the first memory unit to the second memory unit, wherein receipt of said digital ink by said second memory unit causes said second memory unit to associate the track of handwritten information with a stored description of said surface, said stored description being identified by said surface identity.
