Accessibility – a universal requirement in a world of 7 billion people
2 December 2011
- An estimated 15 per cent of the
world’s population lives with a disability. If
family members or care-givers are included, one
quarter of our global population is directly
affected by disability. And a growing and
increasingly “greying” population, coupled with
medical advances, means that more people than
ever will be living with a disability in the
future. Information and communication
technologies (ICTs), embedded in apparatus, are
already transforming the lives of many disabled
people, through aids to mobility, speech and
hearing, and the performance of everyday tasks.
For its part, ITU strives to ensure that ICTs as
a means of communication – and the myriad and
multiplying benefits and opportunities they
bring are accessible to all, including those
with disabilities.
The United Nations Convention on the Rights of
Persons with Disabilities requires countries to
take “appropriate measures” to:
-
Ensure ICT
and emergency service access to
persons with disabilities on an
equal basis;
-
Promote
access for persons with
disabilities to new ICT,
including the internet;
-
Promote
design, production and
distribution of accessible ICT
at an early stage;
-
Ensure that
persons with disabilities can
exercise the right to freedom of
expression and opinion;
-
Provide
information in accessible
formats and technologies
appropriate to different kinds
of disabilities in a timely
manner and without additional
cost;
-
Urge private
entities that render services to
the public to provide
information and services in
accessible and usable formats
for persons with disabilities;
-
Encourage
mass media (including
information providers through
the internet) to make their
services accessible.
With this human rights framework as a guide, ITU
seeks to ensure that people with a disability
enjoy the same opportunities in life as others
and that accessibility issues are taken into
account in all aspects of its work.
Through its standardization activities, ITU
promotes accessibility standards such as the
well-known “tactile identifier” standard
requiring the middle key (#5) of a keyboard to
be easily identifiable by the visually impaired.
It supports open accessibility standards to
ensure interoperability between different
manufacturers and operators of ICT products and
services. It has also produced a checklist and
guidelines on accessibility for standards
makers.
In addition, ITU encourages development of
products and services aimed at increasing
accessibility, such as the “Total Conversation
Service”, a flexible interface that merges
voice, video and text telephony. ITU also
promotes the principle of “universal design”,
which is defined by the UN Convention as the
design of products and services to be usable by
everyone to the greatest extent possible,
minimizing the need for special adaptations or
different devices for people with disabilities.
Recognizing the clear need to coordinate
technology that can assist viewers and listeners
with disabilities to maximize the benefits
offered by broadcast, cable, IPTV, and the
Internet, ITU recently launched the Focus Group
on Audiovisual Media Accessibility. The aim of
this group of experts will be to make access
service requirements independent of the delivery
platform. ITU also issued a report on
Making TV Accessible to
provide practical information on accessible TV
features like captioning, audio description and
easy-to-use remote controls.
Thus ITU is urging all technology developers to
incorporate the basic building blocks of
assistive technologies into ICTs of all kinds
mobile phones, computers, television, ATMs
(automatic teller machines) and so on – and for
all languages. These building blocks include
text to speech and speech to text software,
interactive voice command, and language rule
tables for Braille transcription.
In fact, many technologies we take for granted
today – automatic door openers, talking ATMs,
touch sensitive keyboards – were created as
assistive technologies. “Eye-aware” programs
that use eye movements like a computer mouse to
highlight and select, drag and drop, and click –
are another technology initially created for
people with disabilities that can be expected to
appear in a growing number of mainstream
applications in the near future.
ITU also advises its Members on how to meet
their obligations on accessibility under the UN
Convention, encouraging the exchange of best
practice and helping to develop and promote
policy guidelines, for example, through
compiling an e-Accessibility Policy Toolkit for
policymakers. It has initiated outreach
programmes, such as the Joint Coordination
Activity on Accessibility and Human Factors, and
the Dynamic Coalition on Accessibility and
Disabilities within the Internet Governance
Forum, which include non-governmental
organizations representing disabled people. And
it works to create greater awareness of
accessibility issues through its conferences and
publications, and provides education and
training on accessible ICTs.
The need for “accessibility” is not confined to
people with physical or mental disabilities.
Anyone can be permanently or temporarily
“disabled”, for example, if they try to receive
a phone call in a noisy environment or speak a
language for which there are few internet
resources. Moreover, we will all grow old and
lose abilities, so that – even if not now we
stand to benefit from accessible communication
in the future.
Indeed, rather than treating accessibility as
important solely for addressing the needs of
people with disabilities, elderly people or
those with temporary impairments, we should
regard accessibility as a universal requirement
that aims to ensure that ICTs of all kinds can
be used with ease by people with the widest
range of capabilities. In this way, all the
world’s people, whatever their individual
abilities or disabilities, stand to benefit from
an “accessible ICT world”.
