Data Input
DATA INPUT METHODS:
Printed questionnaires – Depending on the type of questionnaires some form of optical data
reading dives would be the best method. An OMR or Optical Mark Reader can be used in
conjunction with special paper called mark sense form in order to easily input data from
questionnaires where people just simply mark their answer from an already defined set of
answers to a question. Another type of optical data reading that can be used with questionnaires
is called OCR or optical character reader. This type of data input can be used when the answers
to questions are hand written. According to the Data Identification Systems website (Data
Identification, 2003) OCR is a much faster form of data input then keystroke data entry, not only
is it faster but it is also generally more reliable and more efficient.
Telephone survey – The best way to input data from a telephone survey would be through the
use of voice recognition devices. Voice recognition devices are used to record and convert
speech into text using special software.
Bank Checks – The best method of data input for bank checks is to use what is called MICR or
Magnetic Ink Character Recognition. In this method characters are printed on check using
specialized ink or toner which a sorter or scanner can then read by the inks magnetic signal.
Retail Tags – The best method of data input for retail tags in through the use of Bar Coding. Bar
coding is the method in which merchandise information is printed onto a tag or the item itself
using a bar code. This bar code can then be read later by using a bar code scanner that turns the
bar code into readable text such as the items type, name, price, or product number. This method
is a great way to keep track of inventory and inventory sales.
Long Documents – The best method of data input for long documents are through the use of
scanners. A scanner is used to make digital photo copies of paper documents which can then be
stored, sent, or read in many different file types such as a .pdf format. This method greatly
reduces the time it would take for a person to manually type all the information using a keyboard
as well as reducing the storage space it would take to store the paper documents.
DATA OUTPUT METHODS:
Hand held computer – The best data output method for a hand held computer would be visual
output such as text or low end graphics on an LCD screen. LCD which stands for liquid crystal
display is ideal for hand held computers and helps to make their small size possible. Hand held
computers are not powerful as laptop or desktop computers so most output should be in the form
of text and simple graphics.
Color Photograph – The best method of output for a color photograph would be through a high
resolution printer using special photo paper. This method can be used to reproduce color
photographs of different dimensions. A lot of printers now have the capability to print pictures
stored on digital cameras or memory sticks that connect directly into the printer bypassing the
computer altogether and reproduce quality color photograph reproductions of the original
picture.
