Pen system for recording handwritten information
First Claim
1. A pen system for recording a track of handwritten information, said system comprising:
- (A) a handheld pen device comprising;
an image sensor for optically sensing a position-coding pattern printed on a surface, said position-coding pattern identifying an identity of the surface;
a processor for decoding imaged portions of the position-coding pattern and generating digital ink representative of the track of handwritten information and the identity of the surface; and
a first memory unit, located in the pen device, for storing said digital ink; and
(B) a second memory unit located in an external data storage device,wherein said pen device and said second memory unit are connected in such a way that transmission of said digital ink is caused to occur automatically from the pen device to the second memory unit, and 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 corresponding to said surface identity.

Abstract
A pen system for recording a track of handwritten information. The system includes a handheld pen device having an image sensor, a processor and a first memory unit. The pen device generates digital ink by interacting with a coded surface and transmits the digital ink to a second memory unit located in an external data storage device. The pen device and the second memory unit are connected in such a way that transmission of the digital ink is caused to occur automatically from the pen device to the second memory unit. Receipt of the digital ink by the second memory unit causes the second memory unit to associate the track of handwritten information with a stored description of the surface. The stored description corresponds to the surface identity.

10. A method for memory management in a pen device, which is arranged to record a track of handwritten information created by the pen device, comprising the steps of:
-
imaging a position-coding pattern printed on a surface as the pen writes handwritten information on the surface, said position-coding pattern identifying an identity of the surface; decoding imaged portions of the position-coding pattern; generating digital ink representative of the track of handwritten information and the identity of the surface; transferring at least some of the digital ink from the pen device to a second memory unit in an external data storage device in such a way that transmission of said recorded information is caused to occur automatically from the pen device to the second memory unit as the digital ink is formed; and associating the track of handwritten information with a stored description of said surface, said stored description corresponding to said surface identity. - View Dependent Claims (11, 12, 13, 14, 15)
