OMR full form

The full form of OMR is Optical Mark Recognition. OMR is a special type of optical scanner used to recognize the type of mark made by a pen or pencil. It is used where one of the few options is to be selected and marked.  OMR is an input device that is designed to recognize special types of Signs or Marks. You must have often given exams on OMR Sheet in various types of examinations where you have to fill the circle properly with a Black Pencil. When you give the exams, this OMR sheet is put in the OMR scanner and this scanner puts a laser light on your sheet And scans only those dark circles where you have completely blackened the circles in the OMR sheet, from there the amount of laser comes backless and from where you have not blackened the circles. In this way, this Scanner recognizes your given answers. It is specially used for checking answer sheets of examinations containing multiple-choice questions. The biggest advantage of the OMR Sheet Scanner is that it can check about 10000 copies in 1 hour. But if you enter the data from the keyboard, then the chances of mistakes are very high, however, if you enter the data from OMR then the scope of mistakes is very less. OMR can be used to collect only those data in which more than one option has to be selected i.e. if you want to collect single data then you can use OMR.

Advantages and Disadvantages of OMR

  • The biggest advantage of the OMR sheet scanner is that it can detect about 10000 copies in 1 hour.
  • If you enter data with a keyboard then it is more likely to make mistakes, whereas if you enter data with an optical mark reader then the chances of mistakes are very less.
  • It is necessary to fill the OMR sheet properly because if the mark sheet is not indicated properly then the optical mark reader will not be able to collect that data.
  • OMR can be used only for collecting data in which more than one option has to be selected i.e. if you want to collect single data then you cannot use OMR.

How to Fill OMR

  • Filling up the optical answering sheet, again and again, does not make any sense to the respondent.
  • Completely darken the sphere i.e. if you do not darken it partially then it will not catch the machine.
  • Do not put any marks other than blacks like tick marks or cross marks.
  • Many people leave the circle in half and black, but this will not accept your answer, that is, the machines will not be able to read.
  • Remember while filling the circle, don't go out of your way, that means you have to fill the circle from inside only.
