OMR: optical mark reading

Optical Mark reading (OMR) is a method of entering data into a computer system. Optical Mark Readers "read" pencil or pen marks made in pre-defined positions on paper forms as responses to questions or tick list prompts.

The OMR data entry system contains the information to convert the presence or absence of marks into a computer data file. OMR is a different technology from apparently similar automated data entry techniques, such as Optical Character Recognition (OCR) or barcodes, although in many cases these techniques may be used in conjunction with OMR.

The main advantages of the OMR technology are:

  • simplicity:
    "tick box answers" are marked with a cross or filled in by the user with an ordinary pencil or pen. 
  • reliability:
    the OMR scans the form, detects the presence of marks and passes the information to the computer
  • speed:
    AXIOME readers can read up to 11'000 forms/hour (double sided)
  • flexibility:
    the OMR reader tests for plausibility and transmits the formatted information to the computer. The interpretation, using AXIOME readers, can be very sophisticated: this is more than a means of recording simple « yes » or « no » answers 

When to use OMR:

Applications where OMR stands out as by far the most appropriate means of data capture are characterised when:

- data is to be collected from a large number of sources simultaneously
- personnel collecting data are not regular computer users
- a large volume of data must be collected and processed in a short period of time
- information mainly comprises the selection of categories or "tick box" answers to multiple choice questions.

AXIOME OMR are use in many different field like education, quality control, order taking, statistics and marketing, questionning and votes.
