Flashcards in Input/output for disabled people Deck (10):
1

Touch screens + head wand

For people who can’t use a keyboard allowing input; also helps people with learning difficulties since icons are easier to understand

2

On-screen keyboards

For people who can’t use keyboards (use head wand to select letters)

3

Voice recognition

Blind and partially-sighted people can communicate with a computer using microphone and software (keyboard and touch screens can’t be used)

4

Tracker ball

Easier to use than a mouse if people have problems using their arms and hands or if they have a coordination problem

5

Large font size/use of colour

Helps people who are partially-sighted since the larger icons and/or colourful outputs on large screens are much easier to see

6

Braille printers

Dot matrix printers can be modified to produce raised dots (i.e. Braille), this helps blind and partially-sighted people to read the output

7

Voice synthesis

Loudspeakers and special software are used to output information in the form of sound to help blind and partially- sighted people; it also helps people who have difficulty reading/understanding text

8

Large/concept keyboards

These help people who have difficulty using normal keyboards (either because of difficulty using hands/arms or co-ordination problems)

9

Prediction software

To help dyslexic people when typing

10

Foot activated controls

To allow people with restricted hand/arm movement to communicate.
