An optical answer sheet or bubble sheet is a special type of form used in multiple choice question examinations. OMR is used to detect answers. The Scantron Corporation creates many optical answer sheets, although certain uses require their own customized system. [citation needed] Optical answer sheets usually have a set of blank ovals or boxes ...
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.

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 ...
Multiple choice questions are tested using a standardised optical answer sheet that uses optical mark recognition for detecting answers. This exam is held annually on the first Monday of September. The score is calculated based on a bell curve, thus the passing grade is reflected by the yearly performance.
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.
