An Input Device is any peripheral computer hardware used to
provide data and control signals to an information processing
system, i.e. a Computer.
Many input devices can be classified according to:
modality of input (e.g. mechanical motion, audio, visual, etc.)
the input is discrete (e.g. key presses) or continuous (e.g. a
mouse's position, though digitized into a discrete quantity, is
fast enough to be considered continuous)
the number of degrees of freedom involved (e.g. twodimensional traditional mice, or three-dimensional navigators
designed for CAD applications)

There are many examples of Input Devices that can benefit
Disabled people such as Braille keyboards for blind people.
Specialist mice and keyboards that require no strength to use
are for people who have limited or no use with their hands.
Speech Recognition Software can also help people with the
above problems and is also useful for everyday life for nondisabled people as it makes life simpler and can prevent RSIs,
or Repetitive Strain Injuries, which can occur from using a
Computer too much.
There is also Screen Magnification software, again for visually
impaired people and Communication and Translation
software for deaf people.
