How does the OMR Reader work?

OMR technology is used in our daily lives. It is designed to detect the presence of marks on the answer sheets. Also, it is an efficient system for reading bulk data, MCQ answers, and processing in a short time. The OMR sheet goes through the OMR reader, which evaluates the marked areas and extracts information, and is preserved in a separate file. It offers scanning credibility for generating data-driven reports. However, it comes with eminent scanning features that can scan many answer sheets at a time with any ordinary scanner. 

How OMR Reader works?

What is an OMR reader? 

OMR reader refers to the method of recording data that is present in the OMR sheet in the form of a response. It collects a large amount of data in a short time. The information comprises selected categories in multiple-choice questions. In addition to multiple-choice questions, it can read names, ID numbers, and other non-multiple-choice answers. Collecting data with OMR sheet reader software is accurate. Although, OMR technology has continued to evolve. In conventional OMR sheet reading, you need special scanners and experts for scanning. It is expensive and takes a lot of time. Whereas, OMR software is becoming popular for its quick scanning and processing. 

How does it work? 

The working of OMR sheet reader software is based on the principle of ‘Law of reflection’ that implies that the light follows the angle of incidence equal to the angle of reflection. It implies that a lighter surface reflects more light compared to the darker one. Accordingly, OMR software uses a sensor to identify the dark-marked area on the OMR sheet. 48 sensors do this job. It will convert information into a data file for storage. You need to adjust the setting of the OMR software and put OMR sheets in the scanner. Then you can select the option and it can read accordingly. No software can work directly from the computer. 
OMR technology is prevalent in the education sector. After the current medical crisis, universities, schools, and colleges are dependent on OMR based examination. It revolutionized the evaluation process for the exam authorities. It is providing accurate and data-driven results for analyzing the student’s performance. Moreover, It is easy for the examination authorities to use it, and it is cost-effective as well. Information will be stored in the data file after the processing of the OMR sheet.
