THE DIGITAL PEN
From ink to digital data: quick and easy
A digital pen looks, feels and writes like a normal ballpoint pen. However, it contains an integrated digital camera, an advanced image microprocessor and a mobile communications device for wireless connection.

Using a digital pen you can capture, store and then securely send the handwriting, enabling you to easily convert ink to digital data – right away. 

The pen camera takes snapshots
In combination with a surface with the Anoto dot pattern printed on it, a digital pen starts digitizing handwritten text the moment you put pen to the surface. The pen reads and records pen strokes in relation to the barely visible pattern.

As you write, the camera built into the pen automatically takes digital snapshots of the dot pattern at a rate of between 50 and 100 images per second. Every snapshot contains enough data to enable the pen’s image microprocessor to determine the exact position of the digital pen and what it writes or draws. 

Pen data ready for transfer
In addition to capturing the coordinates that enable accurate recording of the handwriting, the digital pen appends key data about the handwriting context. This includes the exact time it was written and the identity of the writer – every digital pen has a unique pen ID, which is included every time data is sent from the pen. The pen data also includes details on the specific paper form and page.

All this data is then retained in the pen’s memory. The digital pen can store up to 50 full A4/Letter size pages of handwritten data. With the handwritten form or document completed and pen data captured and stored, the user is ready to transfer data from the pen.
