What is the Full form of OMR?
The full form of OMR is Optical Mark Recognition. OMR acknowledges human-created marks on a specially printed paper or journal used in experiments, surveys, and so on. It is widely used where the huge number of candidates apply and to evaluate data with consistency and immediate effect. Pieces of information from the documents can be read using the OMR reader.
A datasheet is scanned via a scanner which focuses a light beam on the form paper and identifies areas of minimal light transmission, i.e. marked areas reflecting less light compared to blank zones. It provides an error of less than 1 per cent.
Uses of OMR
- Insurance and Banking applications
- Evaluation & Feedback form
Advantages of OMR
- Previously, a special type of paper, ink and input reader were needed for the OMR systems that limited the questions being answered.
- People may now ask the right questions and develop their models.
- It takes less than five milliseconds on average for testing.
- Users may use circle, mark, square, ellipses of any kind.
Limitations of OMR
- Users can not gather large volumes of text as it complicates the results.
- Data can be lost in large text.
- Only MCQs (multiple choice questions) are favourable.
