Optical Mark Reader (OMR) is a high-tech data input device integrated optical and electrical technology. It is a powerful tool for speedy automatic data capture, thousands of data bytes per second, several hundreds of times faster than manpower, especially it can work for a long time without break.
Optical Mark Reader (OMR)uses infra-red light to scan marks on prepared forms such as multiple- choice examination answer sheets or lottery tickets.
The input and output devices of a computer are normally abbreviated as I/O devices.There are a variety of input units,which are used by computers.THE MOST COMMONLY USED UNIT OF THIS TYPE IS A KEYBOARD AND A MOUSE OF A DESKTOP COMPUTER.Special purpose units are scanners,magnetic ink character reader,optical mark reader,optical character reader and bar code reader.
A special scanning device that can read carefully placed pencil marks on specially designed documents. This is an input device.

When a multiple choice test is answered, a pencil mark is drawn in a small area (often looking like this [ A ] before completion) on an answer sheet to indicate the chosen response. The sheets are then fed into a machine which automatically reads the position of these marks, relays this information to a computer which interprets the data, processes it against a programmed data base and produces a response. In a test, the result is displayed as marks or a percentage. The system can also be used to compile reports or supply a fast way of entering numbers for a lottery draw.The machine that reads the sheets is called an Optical Mark Reader (OMR for short). It works by light reflecting off the paper being picked up by a sensor. Where there are marks, less light is reflected and the relative position of the mark indicates the answer given. The position of the marks is calculated with the help of fixed marks on the paper which indicate the origin point. Some machines are programmed so that it doesn't matter which way round the paper is inserted, it still gives the desired data.The system does rely on the use of specific forms: blank paper with lots of pencil dots is not an option!
