Disabled people input- output devices

1. Braille keyboard

   • Braille keyboards are specialty keyboards that contain single keys that represent each of the dots in a braille cell.
   • To type a letter in braille the user would press a combination of the keys needed to create that braille character.

2. Pipes / sip and puff

   • Sip and Puff (or SNP) devices allow folks who are unable to use a manual device access computers and other vital technology.
   • Users “take a sip” or “blow a puff” of air into a wand that resembles a straw to create air pressure.

3. Foot mouse

   • Moving the cursor or scrolling a page or a document is extremely intuitive, taking just a few seconds to get.
   • To scroll, simply twist the mouse on itself. Rotating the device controls scrolling.

4. Head mouse

   • The CNN transforms the head movements to the actual coordinates of the mouse
   • The designed system allows people with disabilities to control a mouse pointer with head movements and to control mouse buttons with blinks. The results of the experiments demonstrate that this system is robust and accurate.

5. Eye typer

   • This can be used by people who cannot use a hand or foot operated mouse and a conventional keyboard.
   • A camera is mounted onto the computer and it is set to focus on the user's eye. The camera determines where the user is looking and monitors movements made by the eye.
