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 software interprets the output from the scanner and translates it into the desired ASCII output. OMR does not recognize hand-printed or machine-printed characters and does not make an image. This is frequently used for check marks on questionnaires, ballots, tests and reports.
