Which combination of devices should be used to read the marked answers and separately digitize the printed text in a document containing handwritten checkboxes and printed text ?
OMR and OCR
The document holds two different kinds of content, so two different readers are needed, and each one is matched to what it can actually interpret.
The ticked checkboxes are marks in fixed positions, and the device built to sense the presence or absence of a mark at a known location is the Optical Mark Reader (OMR). It does not try to recognise shapes, only whether a position is filled, which is why it is used for answer sheets and survey forms.
The printed text has to be turned into editable characters, and that is the job of Optical Character Recognition (OCR), which identifies the shape of each glyph and maps it to a character code.
The other devices cannot do this work. MICR reads only the magnetic-ink characters on the bottom band of a cheque, and a barcode reader decodes striped or matrix symbols, not free text or tick marks.
Hence, the answer is OMR and OCR.
