7.5

Knowing this, the best practice when creating fields is that they have, at the very least, a 7mm margin on each size of the
actual area you want to capture from. For example, an effective 30mm wide pattern will actually be 44mm wide using these
margins. The margin should be for both the vertical size and the horizontal size.
Distance between patterns
In implementations where a lot of patterns need to be close together (a questionnaire, multiple choice question, checkmarks,
etc) it is important to understand the risk of then pen writing across multiple fields on the paper. People using the pen may, for
example, make a very broad checkmark which would bleed over to the next field. This can cause PlanetPress Capture to
detect the ink as being present, and thus trigger whatever that field does.
PlanetPress Capture ICR
The term "ICR", which means "IntelligentCharacter Recognition"is an evolution on the popularly-known "OCR", which is "Opti-
cal Character Recognition". The difference between the two is easily explained:While OCRcan only recognize characters
using the finished shape (for example, in scanned documents and pictures), ICRrelies on much more data which is provided
by the Anoto Digital Pen:the path that the pen takes, the exact timing of this path, start and stop points, etc. This extra infor-
mation boosts the recognition rates of characters by a wide margin.
It's important to note that both OCRand ICRare relatively loose terms - that is to say, they can have different specific mean-
ings depending on the technology used, but in their general sense mean the same thing. When using the term ICR, we use the
above definition for convenience.
The PlanetPress Capture ICRengine is only available with PlanetPress Production version 7.5 and higher.
An ICRWorkflow
The ICRengine in PlanetPress Suite is used in conjunction with PlanetPress Capture, translating the ink from the Anoto Digital
Pen into separate characters, or text, that is readable by the suite. Multiple components are required in order for the ICRto
work:
l In PlanetPress Design, a Capture Field Object must be added and the Perform ICRoption must be activated (See
the Capture Field page in the PlanetPress Design User Guide). This must be either a Multi-Area Field or a Text Field.
l The Capture Fields Processor must have the Perform ICRRecognition option checked, and language needs to be
selected.
l Once the ICRdata is available, do something with it. This is done by reading the ICRdata that is available in the meta-
data generated by the Get Capture Document task.
l The metadata is also readable by the Capture Condition task, including the captured text and the reliability of this text.
The Workflow as such is the following:
