Optical mark readers (OMRs) work by detecting the presence or absence of marks on a specially designed sheet, such as a test or survey form. When the sheet is scanned, the OMR uses light reflection to identify marked areas, typically where respondents fill in bubbles or checkboxes. The reflected light is interpreted by the OMR's sensors, which convert the data into digital form for analysis. This technology is commonly used in educational assessments and data collection due to its speed and accuracy.
