4}Digitizing
Tablets: Digitizing tablets are an input
device which is used to input drawings and sketches in the computer. A
digitizing tablet consists of an electronic tablet and a cursor or
pen. Images are usually drawn onto a flat surface with a stylus and then appear
on a computer monitor or screen. It receiving information represented in
drawings and sending output to a CAD (computer aided design) application and
PC-based software like AutoCAD.
5} Touch Sensitive Screen: A touch sensitive screen is working both as input and output device. Touch-sensitive control-display units (CDUs) were evaluated for commercial aircraft flight decks in the early 1980s. A touch panel is a piece of equipment that lets users interact with a computer by touching the screen directly. Incorporating features into the monitor like sensors that detect touch actions makes it possible to issue instructions to a computer by having it sense the position of a finger or stylus.

Space Mouse: Space Mouse is a
peripheral tool for controlling three-dimensional objects created by computer
programmers. A three-dimensional mouse has its own system of controls and its
own signals that need to be interpreted by an operating system and/or
application.Space mouse is 3D Controller designed for manipulating objects in a 3D environments. It can 3D cameras at different angles to position and view the object.

8} Digital Still Camera: A Digital still
camera is a type of input device which is used in photography. Traditional cameras capture
light into photographic film but Digital camera uses electronics to store
photographs.
The use of photographic film was pioneered by George
Eastman, who started manufacturing paper film in 1885 before switching to
celluloid in 1888-1889. His first camera, which he called the
"Kodak," was first offered for sale in 1888.

Optical Mark Reader (OMR): OMR is an input
device which is used to entering data in the computer. Optical Mark Reader
reads the pencil or pen marked made by human to capturing document forms such
as surveys and tests and save the data into an output file which you can use to
perform further analysis. They are used to read questionnaires, multiple choice
examination paper in the form of lines or shaded areas. Michael Sokolski (September 25, 1926 – June 13, 2012) was a
Polish-born American design engineer who is the inventor of OMR.

Image Scanner: Image Scanner is a device which is
used to Scan the any hard copy of any image of paper in the Soft copy of computer
system to store data for further use or analysis. Like we can upload our documents
image to fill up the form of competition or school/college registration. There are
special models for scanning photo negatives, or to scan books. In
the computer, the signal from the scanner is transferred to a
digital image. Russell
Kirsch and his team at the US National Bureau of Standards in the
year 1957 built the first image drum scanner.
There are four
types of scanners:
1.
Flat-bed Scanner
2.
Sheet-fed Scanner
3.
Drum Scanner
4.
Portable Scanner
1} Flat-bed Scanner: A flatbed scanner is an optical scanner which
makes use of a flat surface for scanning documents. The scanner is
capable of capturing all elements on the document and does not require movement
of the document. A Flatbed scanners often come with sheet
feeders for scanning multiple sheets of paper rather than one at a time.
2} Sheet-Fed Scanner: A Sheet-fed scanner
is also known as Automatic document feeder(ADF) is a digital imaging system
which is specifically designed for scanning loose sheets of paper. It is widely
used by business organizations to prepare their loose papers. They are
capable of handling, duty cycle rating, speed (pages per minute),
and duplex capability.
3} Drum
Scanner: A Drum Scanner can capture highest resolution of image. In large format photographers there are really just a few options when
it comes to digitizing our beautiful sheets of film: Flatbed scanners like the
Epson v700/750 or v800/850, a few very expensive dedicated scanners like the
Hasselblad Flextight, or a drum scanner.
4} Portable Scanner:
A portable scanner is a type of hand-held scanner. This device work same as
flat-bed scanner which convert any of a physical document in the Digital
format. This device is especially useful when
space is a concern, as flatbed scanners tend to take up a large amount of space.
