What is the full form of OMR?

The full form of OMR is Optical Mark Recognition. OMR recognises human-created marks on specifically printed papers or journals used in studies, surveys, and other applications. It is often utilised in situations when a large number of candidates apply, and it is used to analyse data with consistency and immediate effect. The OMR reader can be used to read information from documents.

A datasheet is scanned using a scanner, which focuses a light beam on the form paper and identifies areas of limited light transmission, i.e. marked areas that reflect less light than blank zones. It has a margin of error of less than 1%.

Uses of OMR

• Surveys
• Insurance and Banking applications
• Examinations
• Election
• Evaluation & Feedback form

Advantages of OMR

• Previously, OMR systems required a unique type of paper, ink, and input reader, which limited the number of questions that could be answered.
• People can now develop their models by asking the proper questions.
• Testing takes less than five milliseconds on average.
• Users may utilise any type of circle, mark, square, or ellipse.

Limitations of OMR

• Users cannot collect considerable amounts of text because it complicates the findings.
• In the large text, data can be lost.
• Only multiple-choice questions (MCQs) are acceptable.
