Reading information that people have marked on surveys, tests, and other paper documents are known as optical mark recognition. OMR is used to read multiple choice exam papers that have colored regions for the multiple choice questions.
What is OMR?
By recognizing specific markings on a document, optical mark recognition (OMR) is an electronic technique for collecting data that has been handled by a human. The optical mark recognition method is typically carried out with the use of a scanner that measures the light’s passage or reflection through the paper. Marked areas of the paper will reflect less light than unmarked areas, giving them a lower contrast reflectivity.
Optical mark reading is another name for optical mark identification, however, Scantron is the more well-known brand name.
