DISABILITIES
TYPES OF DISABILITY WEBSITES
There are many different types and styles of
websites for disabled people including;

 Deaf people
 Dyslexia
 Colour blindness
 Epilepsy

LOW VISION, PARTIAL SIGHT OR TOTAL
BLINDNESS

People with low vision may suffer from extreme forms of
short-sightedness or long-sightedness, or their vision may
be blurred or unclear in other ways.
When interacting with partial sighted or completely blind
people, websites typically need to do one or more of the
following:

Adjust the size of the text on their browser to a larger
scale
Use assistive software to magnify the web page
Use high contrast colour schemes- making it easier to
view.
Use screen readers
Use braille display
COLOUR-BLINDNESS


A common misconception is that people with colour-blindness only
see in black and white (or greyscale). Whilst that is true of one
form- there are many types of colour-blindness and each one has
differing effects on people’s vision of colour. Colour-blindness is
much more common in men than women.
Mostly when interacting with people who suffer from colourblindness, websites won’t need to use any special techniques or
software. However the following features of web pages make
viewing websites easier for people with colour-blindness
Major colour contrast between texts and background
 The use of colours alone to indicate meanings

DEAFNESS

Like blindness, deafness can manifest itself in different
degrees – from slight impairment to complete loss of
sensation. As the web is becoming an increasingly popular
experience, those suffering with deafness are becoming
more catered for.
Websites could use these techniques to help deaf people use
the internet;

Video content with captioning
Audio content or signals with full captioning
No background noises that are too loud
Subtitles located on the background noises

DYSLEXIA


Cognitive impairments are a very broad grouping including
a wide number of conditions. They include language-based
difficulties such as dyslexia, intellectual disabilities and
other conditions such as autism or attention/ hyperactivity
disorder (ADHD).
Websites for people with dyslexia or other impairments
may need to do one of the following to help them access the
web:


Provide screen readers
Provide text-to-speech software
Use simpler and less complex language
Use shorter sentences
Sufficient instructions on how to use functionality and what they’re
for
Make pages require a slower response
EPILEPSY

Epileptic seizures can be triggered by flashing or
strobe lights at certain frequencies. They can also
be triggered by flickering or blinking content in
web pages.

It is important that websites for people with epilepsy
do not present such content.

Hospitals can use this to allow all types of people
with various disabilities to view and understand
their situation and medical records.
 The hospitals could also recommend different

 By using appropriate websites all patients will be
able to fully understand and tackle their
disabilities via the internet.
