In the picture A, we can see a
blind student using an adapted
keyboard with the presence of his
teacher. The headphones and the
screen probably use a program to
allow him to hear the text from
the screen
In the picture B, we can see
a blind girl using a screen
magnifier, with the presence
of his teacher. A kind of
software that enlarges text
and images
In the picture C, a
motor-impaired person
is using a pneumatic
switch to operate the
computer
In the picture D, a
motor-impaired user is
unable to type in a

the video camera on it
use a special software to

gaze point on the screen
