What is OMR in with respect to computers?

OMR is a popular electronic method which involves the process of collecting human marked data (generally on paper) and converting it into a form which is readable by a computer. 

This technology is generally used by the educational institute or by any institutions who conduct examinations. Multiple-choice questions exams, surveys, assessments etc are evaluated very easily if optical mark recognition is used. 

OMR mainly works with documents which are of fill in the bubble or mark type. This technology was developed in the 1930s and is still a very popular way of evaluating multiple choice documents.

Advantages of OMR:

  • The evaluation by OMR scanner is more accurate than that of a human

  • The evaluation can be done at a much faster pace

  • Very useful in case of large surveys

  • High cost benefits if the a large number of documents are to be scanned

  • Easy to implement and support 

  • Data can be stored directly in the cloud and hence can be transferred wherever required

  • Helps in grading without being biased 

How do OMR scanners work?

  1. OMR scanner focuses a beam of light on a dedicated area.

  2.  Since the marks or bubbles on the OMR sheet are filled (generally with black colour) they will absorb this light.

  3. The OMR sheet being white (or similar shades) will reflect back the light

  4. Now with the help of computing processes the areas where lights weren’t reflected will be used for evaluation.
