Problems and Solutions in Accessibility and Usability of ICT for Disabled People
Gill Whitney

I have worked to use the practical use of regulation, legislation and standardisation to support Digital Inclusion (or the belief that these are tools which should be used when relevant).
My Background
Digital Exclusion
“…increasingly we find that vital information, communications, better shopping and financial deals, and some public services are now only available online. Indeed, many of these facilities are most beneficial to those who are not using them. There is concern that those who are not using digital technology, and indeed those who wish to, but are trying to “catch up”, are excluded.”

Real people have complex needs and lead complex lives
A person with diabetes may have reduced sensitivity in their hands and feet and be blind or partially sighted. Their requirements could include some or all of the requirements for a user with mobility, dexterity and visual impairment. They may also have a lower level of literacy and also of digital literacy and live in a area of slow (or no) broadband access.
Example:
A visually impaired user who wishes to access audio described television programmes would need:
to be able to have access to digital television,to be able to select the audio description
service, to be able to find out which programmes have
audio description (most likely through a web based television guide).

The use of information systems for the Office of the High Commissioner for Human Rights and the United Nations Committee on the Rights of Persons with Disabilities, 2012 to 2013
I was one of the authors of the recent revision of ISO/IEC Guide 71:2014 Guide for addressing accessibility in standards, including leading the task force on process.
Recent Projects
Digital Inclusion
Information and communication technologies, or ICTs, play a key role in all our daily lives, in our work, education, public services and in our homes. More and more new and complex services can be accessed electronically through a range of devices. Yet access, service design, personal capacity, trust, skills, willingness and awareness can represent significant barriers to some of the very people able to benefit most from these services.
Transfer of Accessibility Information
The aim of this lecture is to look at the challenges faced by people who are restricted in online access – and why this matters.
Key issues: Discrimination, Legislation Regulation
What needs to be done to enable Digital Inclusion?
Solutions exist that can be used, therefore you need;Background knowledge of existing best practice design
solutions (codified in standards or available in existing prize winning designs).
Background knowledge of existing governmental and other initiatives used to promote digital inclusion.
Knowledge of when new solutions must be sought.
Transfer of Accessibility Information
The successful transformation of accessibility information from the `accessibility community' to others who are responsible for the specification, design and maintenance of technology.
The transfer of accessibility information is not straightforward for two reasons; The political angle – as accessibility is firstly driven by
human rights legislation. The fact that the audience for the accessibility
information may be unwilling recipients of the information (not for reasons of wishing to discriminate but simply for reasons of cost, time, etc.).
Transfer of Accessibility InformationOngoing research makes use of communication
theory to pass information from users who have experienced accessibility problems to the designers and specifiers of the systems.
Communication theory `that richer, more personal means of communication’ are more effective.
The visually impaired end users have a full power of veto on any editing to the messages that have been created from their experiences.
It is hoped that these messages will support the use of relevant accessibility standards.
Examples of Mandates and Legislation which drive Accessibility
The Equality ActSection 508Mandate 376 - standardisation mandate to CEN,
CENELEC and ETSI in support of European accessibility requirements for public procurement of products and services in the ICT domain.
M/473 Standardisation mandate to CEN, CENELEC and ETSI to include “Design for All” in relevant standardisation initiatives
European Public Procurement
Public Procurement is the term used to describe the purchasing of works, supplies and services by national, regional and local public bodies, including central government, local authorities, fire and police authorities, defence, health services, joint consortia of public bodies, and public and private utilities.
The annual value amounts to around £500 billion, estimated at around 11.5% of EU Gross national product.
ISO/IEC 40500:2012Information technology -- W3C Web Content
Accessibility Guidelines (WCAG) 2.0
ISO/IEC 40500:2012 [Web Content Accessibility Guidelines (WCAG) 2.0] covers a wide range of recommendations for making Web content more accessible. Following these guidelines will make content accessible to a wider range of people with disabilities, including blindness and low vision, deafness and hearing loss, learning disabilities, cognitive limitations, limited movement, speech disabilities, photo-sensitivity and combinations of these. Following these guidelines will also often make your Web content more usable to users in general.

The Coles web accessibility case
Gisele Mesnage, legally blind from birth, who stated to the media that the evolution of online grocery shopping had “changed her life”.
"For about three-and-a-half years I managed to use the website, select the delivery time, and do my orders unassisted.
The delivery options were broken in a 2013 update. http://www.accessiq.org/news/w3c-column/

ISO/IEC Guide 71:2001Guidelines for standards developers to address the needs of older persons and
persons with disabilities
This Guide provides guidance to writers of relevant International Standards on how to take into account the needs of older persons and persons with disabilities. Whilst recognizing that some people with very extensive and complex disabilities may have requirements beyond the level addressed in this Guide, a very large number of people have minor impairments which can be easily addressed by relatively small changes of approach in standards, thereby increasing the market for the product or service.
The social model of disability
Disability is created by barriers in society.The barriers generally fall into 3 categories:
the environment – including inaccessible buildings and services
people’s attitudes – stereotyping, discrimination and prejudice
organisations – inflexible policies, practices and procedures

ISO/IEC Guide 71:2014Guide for addressing accessibility in
standards
ISO/IEC Guide 71:2014 provides guidance to standards developers on addressing accessibility requirements and recommendations in standards that focus, whether directly or indirectly, on systems (i.e. products, services and built environments) used by people.

Human abilities and characteristics
Combination of the social and medical models of disability.
Both models used by standardisers. Other models exist.
