What is the full form of OMR

OMR: Optical Mark Recognition

OMR recognizes marks made by human beings on a document or specially printed papers used in examinations, surveys, etc. It is generally used where a large number of applicants apply and data has to be processed immediately and with accuracy. Data is read from the document with an OMR reader.

Data sheet is scanned through a scanner that shines a beam of light on the form paper and detects the areas of limited light transmittance i.e; marked areas as they reflect less light in comparison to blank areas. It gives less than 1% error.

Applications

• Examinations
• Surveys
• Evaluation and Feedback form
