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.
Earlier, special paper, special ink and special input reader were required for the OMR systems which restricted the questions to be asked. Now user can create their own forms and ask suitable questions. It takes less than 5 milliseconds on average check. User can use any type of mark square, ellipses, circle.
