What is OMR?
OMR (Optical Mark Recognition) is the translation of marks - or the absence of marks - but not the shape of the mark on forms that have small circles ("also called bubbles") completed by the respondent.

This is frequently used for check marks on questionnaires, ballots, tests and reports.
