Optical mark recognition (OMR) collects data from people by identifying markings on a paper. OMR enables the hourly processing of hundreds or even thousands of documents. A common application of this technology is used in exams, where students mark cells as their answers. This allows for very fast automated grading of exam sheets.
Video of the process of scanning and real-time optical character recognition (OCR) with a portable scanner. Optical character recognition or optical character reader (OCR) is the electronic or mechanical conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene photo (for example the text on signs and ...
The IBM 1231 is an online optical mark reader that can read and score 2000 test answer sheets per hour, depending on downstream operations. [6] The correct answers for the test can either be entered using a master sheet (like the 1230) or sent to the 1231 using the optional master-mark special feature. [7]
The company is well known for their machine-readable paper forms on which students mark answers to multiple-choice test questions [1] and the optical mark recognition (OMR) and imaging scanners that read them. To analyze those answers, the machines use OMR- and image-based data collection software. In addition to its forms and scanners ...
He was the engineer who developed Scantron's multiple choice answer sheets, which use a number 2 pencil to read and grade a student's test results. [3] He held several of the company's optical mark recognition (OMR) patents in the United States. [3] The introduction of the Scantron test revolutionized tests given in all forms of formal education.

Earliest ideas of optical character recognition (OCR) are conceived. Fournier d'Albe's Optophone and Tauschek's Reading Machine are developed as devices to help the blind read. [1] 1931–1954 First OCR tools are invented and applied in industry, able to interpret Morse code and read text out loud.
The Votronic, from 1965, was the first optical mark vote tabulator able to sense marks made with a graphite pencil. [1] The oldest optical-scan voting systems scan ballots using optical mark recognition scanners. Voters mark their choice in a voting response location, usually filling a rectangle, circle or oval, or by completing an arrow.
