Usage Scenarios

Mobile OCR Server based OCR
Application Areas On Device OCR for instant text re-use
e.g. store captured text as notes,
apply text to speech,
send info via mail or
send text to translation service
Server based OCR allows
Data extraction of specific fields of interest
Usage of big databases (verification
& additional meta data)
Information
to be processed
Printed Text Printed text,
Hand filled survey forms,
Checkmarks,
Barcodes
Application Types “Thick” Apps with OCR technology included,
OS native,
“Thin” Client approach
Image capture, data communication with the back-end,
More generic Apps for multiple devices
for simple task and quality check
before the documents are sent to the server
