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-
choicequestion, 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. Basically an OMR
Reader is only intelligent to accurately give the postion
of the marks , interpretation of marks is an important aspect
and more than often known as Template Creation
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
