  2. What are Input Devices? • 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. two-dimensional traditional mice, or three-dimensional navigators designed for CAD applications) Source: http://en.wikipedia.org/wiki/Input_device

  3. Examples of Input Devices • Keyboards • Mice • Webcams • Microphones • Digital Pens and Tablets • Joysticks • Wii Remote • Games Console Controllers (eg Xbox 360, PS3 etc) • Touch Screens • Scanner • Digital Camera Source:http://www.wong-sir.com/cit/information_processing/input_devices.htm

  4. How Input Devices can benefit Disabled People • 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 non-disabled 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.
