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 "Optical 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 information
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 dif-
ferent specific meanings 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.
Note: The PlanetPress Capture ICR engine is only available with PlanetPress Workflow version
7.5 and higher.
An ICR Workflow
The ICR engine in PlanetPress Workflow 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. Mul-
tiple 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 lan-
guage needs to be selected.
