Short for optical mark reading or optical mark recognition, OMR is the process of gathering information from human beings by recognizing marks on a document. OMR is accomplished by using a hardware device (scanner) that detects a reflection or limited light transmittance on or through a piece of paper.
OMR allows for the processing of hundreds or thousands of documents per hour. For example, students may recall taking tests or surveys where they filled in bubbles on paper (shown right) with a pencil. Once the form had been completed, a teacher or teacher's assistant would feed the cards into a system that grades or gathers information from them.

OCR
Stands for "Optical Character Recognition." OCR is a technology that recognizes text within a digital image. It is commonly used to recognize text in scanned documents, but it serves many other purposes as well.
OCR software processes a digital image by locating and recognizing characters, such as letters, numbers, and symbols. Some OCR software will simply export the text, while other programs can convert the characters to editable text directly in the image. Advanced OCR software can export the size and formatting of the text as well as the layout of the text found on a page.
