Optical mark readers (OMRs) are devices designed to process marked data, commonly used for grading multiple-choice exams and surveys. They work by detecting the presence or absence of marks on paper, usually using infrared light, which allows for rapid and accurate data collection. One interesting fact is that OMR technology can read various types of marks, such as filled bubbles or checkboxes, and can also handle different paper sizes and formats. Additionally, advancements in OMR have led to the incorporation of optical character recognition (OCR) features, enabling the reading of handwritten text alongside marked data.
