4. KEYBOARD :
 A 'keyboard' is a human interface device which
is represented as a layout of buttons. Each
button, or key, can be used to either input a
linguistic character to a computer, or to call
upon a particular function of the computer.
Traditional keyboards use spring-based
buttons, though newer variations employ
virtual keys, or even projected keyboards.
 Examples of types of keyboards include:
 Computer keyboard
 Kier
 Chorded keyboard
 LPFK

5. POINTING
DEVICES :
 A computer mouse
 A pointing device is any human
interface device that allows a user to
input spatial data to a computer. In
the case of mice and touch screens,
this is usually achieved by detecting
movement across a physical surface.
Analog devices, such as 3D mice,
joysticks, or pointing sticks,
function by reporting their angle of
deflection. Movements of the
pointing device are echoed on the
screen by movements of the pointer,
creating a simple, intuitive way to

6. HIGH-DEGREE of FREEDOM
INPUT DEVICES :
 Some devices allow many
continuous degrees of freedom
as input. These can be used as
pointing devices, but are
generally used in ways that
don't involve pointing to a
location in space, such as the
control of a camera angle while
in 3D applications. These kinds
of devices are typically used in
CAVEs, where input that
registers 6DOF is required.

7. COMPOSITE
 DEVICES(P-1) :
Input devices, such as
buttons and joysticks,
can be combined on a
single physical device
that could be thought of
as a composite device.
 Many gaming devices
have controllers like this.
Technically mice are
composite devices, as they
both track movement and
provide buttons for
clicking, but composite
devices are generally
considered to have more
than two different forms
of input.

8. COMPOSITE

DEVICES(P-2) :
Game controller
 A game controller is a device used with
games or entertainment systems to
provide input to a video game,
typically to control an object or
character in the game. A controller is
usually connected to a game console or
computer by means of a wire or cord,
although wireless controllers are also
widespread. Input devices that have
been classified as game controllers
include keyboards, mice, game pads,
joysticks, etc. Special purpose devices,
such as steering wheels for driving
games and light guns for shooting
games, are also game controllers.
Devices such as mice and keyboards
can be emulated with a game pad
through the use of programs such as
'JoyToKey'.

9. GAME PAD (or Joypad)
 A gamepad (also called joypad or control pad), is a
type of game controller held in two hands, where the
fingers (especially thumbs) are used to provide
input. Gamepads generally feature a set of action
buttons handled with the right thumb and a
direction controller handled with the left. The
direction controller has traditionally been a four-
way digital cross (also named a joy pad, or
alternatively a D-pad), but most modern controllers
additionally (or as a substitute) feature an analog
stick.
 Some common additions to the standard pad
include shoulder buttons placed along the edges of
the pad, centrally placed start, select, and mode
buttons, and an internal motor to provide
force feedback.
 Gamepads are the primary means of input on all
modern video game consoles except for the Wii
(though the Wii Remote can function alternately
