Data Input Device - Optical Mark Recognition (OMR) Device

// Description:- // Optical Mark Recognition is the use of shading in of boxes of specific areas of a form to represent data. For example, a lottery ticket; the boxes are shaded in according to the numbers chosen. Consequently, the positioning of the paper for reading must be precise. The lottery card has a number of small squares print ed on the card, that you colour in or mark with a dark pen. he input reader senses those dark squares and converts them in the lottery number which has been selected.

// Advantages:- // // Dis-advantages:- //
 * Good for inputting large volume of data at low cost.
 * Very little training or instruction required to use the forms/card.
 * Good for multi-choice questionnaries.


 * Can only input a limited data set.
 * Poorly marked forms/cards cause errors.
 * Creased/folded forms cause errors.
