Full Form of OMR :
Optical Mark Recognition (or) Optical Mark Reader
OMR Full Form is Optical Mark Recognition (or) Optical Mark Reader. It is a method used to enter data into a computer. It is also called as Optical Mark Recognition. OMR is capable of reading pen or pencil marks present in pre-defined places on a documents or papers. Usually, it reads tick marks or responses to questions on papers. The absence of presence of the pen/pencil marks is then converted for further use. OMR is normally used whenever there is a requirement to collect huge data sources at the same time or at a short period. The rate of error that can happen in OMR method is less than 1%. A typical example OMR application is the multiple-choice exam papers of students attending various public exams all over India. Usage of Bubble sheets is another application.
One is not unfamiliar with an OMR sheet. Optical Mark Recognition has become one of the most commonly and popularly implemented processes for capturing human-marked data. It is essentially a process through which the data marked by humans is captured from documents such as tests or surveys. Let us explore three important aspects of OMR and find out what gives it a special place in the field of assessment. So, here are three things about Optical Mark Recognition, which will hereinafter be referred to as OMR, that you should know about:
OMR software is a computer application which enables OMR on a computer with the help of an Image scanner for processing tests, attendance sheets, tests, checklists and other documents that use OMR. The software is used for capturing data from the OMR based documents and this process of capturing depends upon a host of factors such as designing pattern, and thickness of the paper sheet. One of the earliest OMR software was Remark Office OMR, which used images obtained from common image scanners. The software was released way back in the year 1991. The need for a sophisticated OMR software emerged due to the high cost incurred by OMR systems. An OMR software, apart from being handy and more accurate, incurs less cost upon the person or institution.
An OMR software is additionally used for adding OMR marks to documents, which are to be mailed so that the folder insert equipment can scan them. One such example is Mail Markup manufactured by a UK based company Funasset Limited. Mail Markup enables the user to cause configuration and selection of OMR sequence and application of the OMR mark to the mail documents before printing. There are also open source OMR softwares such as FormScanner, Moodle, TCExam, Shared Questionnaire System, OMR Mark Engine, queFX, etc.
History behind OMR
The first ever mark scanner was developed by IBM under the name 805 test Scoring Machine, which sensed the electrical conductivity of the gravity pencil lead with the help of wire brushes which scanned the page. In the period around the 1930s, Richard Warren did experiments with OMR for test scoring. However, the first successful OMR scanner was invented by Everett Franklin Lindquist, who designed it for better scanning and scoring of his self-designed tests. The current rights to Lindquist’s patent are held by Westinghouse Corporation. IBM made several improvements to its OMR devices. Soon other players entered the market with different kinds of OMR devices.
Usage of OMR
The use of OMR is not restricted to surveys or school tests but has been incorporated by several health care agencies and enterprises. The use has been incorporated with the objective of simplifying the data input processes as well as reducing errors. Some of the applications of OMR are given in the following paragraphs:
- It has found application in the process involving institutional research.
- It is extensively used in consumer surveys.
- OMR sheets are used for conducting tests and assessments.
- It has been used in banking, mortgage loan, and insurance sector.
- In inventory counts and time sheets.
- It is used in product evaluation and data compilation.
- In geocoding.
OMR has different field types, which provide for the format in the desired form. These fields include:
- Grid: In this lines or bubbles are set up in the format of a grid and allows the user to fill in name, ID number, phone number, etc.
- Add: It totals the answers to an individual value.
- Dotted Line fields: It was designed by Smartshoot OMR and allows border dropping such as traditional color dropping.
- Multiple: It provides for several options out of which one has to be selected. It is usually found in surveys and tests.
OMR also comes with disadvantages, despite having extensive applications. OMR can cause complications where a user wishes to collect a larger volume of text information. There can be several accuracies attributed to unnumbered or incorrectly numbered pages, etc. There is a chance that a page is rescanned if proper measures are not placed and can lead to skewed results.
