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.
The competition consists of 15 questions of increasing difficulty, where each answer is an integer between 0 and 999 inclusive. Thus the competition effectively removes the element of chance afforded by a multiple-choice test while preserving the ease of automated grading; answers are entered onto an OMR sheet, similar to the way grid-in math questions are answered on the SAT.
Optical music recognition (OMR) is a field of research that investigates how to computationally read musical notation in documents. [1] The goal of OMR is to teach the computer to read and interpret sheet music and produce a machine-readable version of the written music score.
Michael Sokolski (September 25, 1926 – June 13, 2012) was a Polish-born American design engineer. Sokolski was the inventor [1] of the Scantron OMR scanner, used to scan and grade forms on which students mark answers to academic multiple choice test questions. [2] [3] [4] Sokolski was born near Rovno, Poland (now Rivne, Ukraine) on September ...
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 ...
c) The incorrect response will yield -¼ (25% negative) marks for each question. d) For any combination of more than one option, even if it contains the correct option, the said answer will be treated as incorrect and will yield -¼ (25% negative) marks. e) Not attempting the question will fetch zero mark. Category-2. a) Only one option is correct.

On completion of a learning module a student can use an optical scan-type card to record answers to up to 27 questions, with up to 5 choices per question. [14] They are scanned by the reader and the results are then transmitted to an IBM System/360 in remote job entry mode and can also be printed on the IBM 2740 . [ 14 ]
