Answer

Answer Details

(a) How Optical Mark Recognition (OMR) works:

An OMR reader shines a light onto a pre-printed form and detects the positions where marks have been made by the user (for example, pencil marks in specific bubbles). [1]
The marked positions reflect less light than unmarked areas, and the reader records which boxes or bubbles have been filled in, converting their positions into data. [1]

(b) Two examples of where OMR is used:

Marking multiple-choice examination answer sheets where students fill in bubbles corresponding to their chosen answers. [1]
Collecting responses from lottery tickets where players mark their chosen numbers on a pre-printed grid. [1]

(c) One advantage and one disadvantage of OMR:

Advantage: Large volumes of forms can be processed very quickly and accurately without manual data entry, saving time and reducing errors. [1]
Disadvantage: The system can only read data from specially designed forms with pre-defined positions for marks, limiting the types of data that can be collected to simple choices rather than free-form text. [1]
