Optical Mark Recognition

Optical Mark Recognition (OMR) is a technology used to read marked information on paper forms, like surveys or exams. It works by scanning the document and detecting the presence of marks—such as filled-in bubbles or checkboxes. Software then processes the scanned image, interpreting the marks to extract data. This method is efficient for collecting responses quickly and accurately, reducing manual data entry errors. OMR is widely used in educational assessments, voting systems, and market research, making it a valuable tool for gathering information systematically and effectively.
