Pen system for recording handwritten information

摘要

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.
