Pattern ID
The ID of the Anoto pattern. Represents the pattern on the page. Can be used to retrace the document
to which the pattern belong.
Pattern Sequence
Pattern Sequences enable the multiplication of the number of available pattern by adding an extra iden-
tification to the document. A Pattern Sequence is also attributed to each Anoto Digital Pen, such as an
incoming PGC file will contain the Pattern, on which the Pattern Sequence is added from the pen data-
base. The pattern and pattern sequence refer to a specific document in the database. Signing a doc-
ument with a pen of which the Pattern Sequence does not match that of the document causes
Contamination, which can cause errors or ink to be placed on the wrong document.
Pen ID
The serial number of the Anoto Digital Pen. It is registered in the PlanetPress Capture database and is
present in each PGC file.
PGC File
Pen Generated Coordinates; PGC File containing all ink processed while the pen was undocked along
with the Pen ID. It is possible that a single document requires multiple PGC, just as it is possible that a
single PGC have multiple documents.
Pidget
Type of PlanetPress Capture object. Page element used to give instructions to the Anoto pen, as
opposed to recording ink.
PlanetPress Capture Database
A database containing the list of patterns, sequences, registered pens and documents. The Capture
Database can be used by a single server, or by multiple servers in a Client/Server architecture.
Session
The time spent by the pen between events that trigger a new session. Generally a session refers to any
ink in a single page containing a Capture Pattern. A session can contain ink from multiple fields in any
order. A new session starts whenever a PGC is sent for processing (which erases the data from the
pen).
