digital generation. Read what some people answered when questioned about
the use of computers in their lives.
Computers: friend …
↓
‘I have a GPS, Global Positioning
System, fitted in my car. With this
navigation system I never get lost.
And the DVD recorder is perfect for
my children’s entertainment.’
‘I use an interactive whiteboard, like
a large touchscreen monitor, at
school. I find computers very useful
in education.’
‘Assistive technology, for people
with disabilities, has helped me a lot.
I can hardly see, so I use a screen
reader, a program that reads aloud
onscreen text, menus and icons.’
‘This new HMD, head-mounted
display, allows me to watch films,
and enjoy virtual reality, the artificial
environment of the latest video
games.’
‘The upgraded wireless network at
my university is great: we can
connect our laptops, PDAs and Wi-Fi
cell phones to the network anywhere
in the campus. Communication is
becoming easier and easier.’
or foe?
↓
‘Our
society
has
developed
technological
dependence.
When
computers are down, our way of life
breaks down: planes stop flying,
telephones don’t work, banks have to
close.’
‘Computers
produce
electronic
waste, plastic cases and microchips
that are not biodegradable and have
to be recycled or just thrown away.’
‘They are responsible for health
problems, e.g. computer addiction, an
inappropriate and excessive use of
computers.’

the help of computers, is creating
serious problems.’
‘Citizens may feel a loss of privacy
because of unauthorized use of
personal data or receiving unwanted
electronic messages.’

Computers for the disabled
Can you hear or feel pictures? Can you move something without touching
it? Dan Jellinek went to Los Angeles and found out that you can do all
these things…and more.
Computers have started to change the lives of some disabled people. They can
help them to communicate and to live more independently. The 14th international
conference on computers and disabled people showed some exciting examples.
1.______________.
vOICe is a program that changes pictures into sounds. Different colours and
shapes have different sounds. With practice, blind people can listen to the sounds
and ‘see’ them by using their ears.
2.______________.
The program MouseCAT changes pictures into vibrations on the screen. Blind
people can touch the screen and ‘feel’ the images. They can also use this program
to speak – they write words and the computer says them.
3.______________.
Mindmouse can identify brain activity. It is like a hat. You put it around your
head and operate the computer by thinking.
4.______________.
CharM is a computer system that can identify people’s emotions. In this way,
people who can’t speak can communicate how they feel to other people.
5.______________.
Handy 1 is a robot arm with five different kinds of movement. It can help very
disabled people do activities like eating and drinking.
6._______________.
It is often difficult for them to meet other children. DO-IT is an Internet program
that helps them get help and support from other children who suffer the same
problems.
