Pen system for recording handwritten information
First Claim
1. A pen system for recording a track of handwritten information created by a handheld electronic pen, said system comprising:
- the handheld electronic pen comprising;
an image sensor for optically imaging a position-coding pattern printed on a surface;
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 first memory unit for storing said digital ink; and
a second memory unit located in an external data storage device, wherein said first and second 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, 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 being identified by said surface identity.

Abstract
A pen system for recording a track of handwritten information created by a handheld electronic pen. The pen system includes the handheld electronic pen and a second memory unit located in an external data storage device. The electronic pen has an image sensor for optically imaging a position-coding pattern printed on a surface, a processor for recording the handwritten information as digital ink and a first memory unit for storing the digital ink. The first and second memory units are connected in such a way that a transmission of digital ink is caused to occur automatically from the first memory unit 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.

10. A computer system for receiving digital ink stored in a first internal memory unit of a handheld pen device, said digital ink representing a track of handwritten information recorded from an imaged position-coding pattern and said digital ink identifying a surface identity, wherein said computer system comprises:
-
a second memory unit connected to said first memory unit in such a way that transmission of said digital ink is caused to occur automatically from the first memory unit to the second memory unit; and a processor for automatically associating the track of handwritten information with a stored description of said surface upon receipt of said digital ink, said stored description being identified by said surface identity. - View Dependent Claims (11, 12)
