OMR refers to the technique of converting a handwritten marks into an ASCII value. The Mark is created by filling a circle or a box on a pre-printed form .
The presence or absence of a Mark in a specific location is then converted into a value such as a selection in a multi- choice question,
the selection of one item in a list of several, or even to code a specific numeric or alphanumeric value, such as a date using six columns of 10 boxes or name with 26 columns etc
Thus, if a Mark by itself can only generate a binary choice (presence or absence), the combination of several marks arranged on a form can provide intelligent answers to questions and be used as a fast and
accurate replacement to data entry in many applications.

Optical marks recognition is traditionally performed using Reflective Light Method where a beam of light is reflected on a sheet with marks. (Sekonic Optical Mark Readers , a low priced Japanese Readers are very special )Special forms are created using Timing Marks and color drop-out (depends what reading head you uses , Visible or Infra-red) and are usually referred as Scantron or Sekonic Forms from the name of the vendors that sell these systems.
