Standards relating to the accessibility of ICT systems

Report on International ICT Accessibility Standards Proposed, Being Developed and Recently Published

Richard Hodgkinson FISTC,
5th July 2007

Overview:

This report covers current international activities in the development of standards, technical reports and guidelines that include accessibility requirements and recommendations for ICT products.

Accessibility standards are developed globally by committees of the International Organisation for Standardisation (ISO), the International Electrotechnical Commission (IEC), Joint Technical Committee (JTC) 1 of the ISO & IEC, national standards bodies (e.g. the BSi, ANSI, AFNOR, DIN…) and many other organisations.

Proposed new standards and activities:

Note: The following “projects” are currently under discussion within various standards organisations. In due course Working Drafts and New Project proposals will be submitted for international ballot. If the balloting is successful (acceptance of the project, commitment of experts, offer of a project editor, etc) the projects will be assigned to the appropriate standards organisations or new organisations will be created.

ISO 9241-129 – Guidance on software individualisation

The new project proposal for this new standard was approved by international ballot (2007-07) within ISO/TC 159/SC 4. It has yet to be allocated to a Working Group.

It will address ergonomic requirements and recommendations for individualization of
human-computer interactions and will provide support for the development, evaluation, and procurement of user interfaces that incorporate individualization.

ISO 9241-135 – Voice user interface design

This potential standard is being discussed in ISO/TC 159/SC 4/WG 5 (Software ergonomics and human-computer interaction) and in due course a Working Draft will be prepared together with a New Project proposal for international ballot.

This standard would provide recommendations and guidelines for the user-centred design of software user interfaces for voice controlled dialogue systems to increase usability.

ISO 9241-152 – Interpersonal communication – Usability and accessibility of computer-based data and voice communication

This potential standard is currently being discussed and developed within ISO/TC 159/SC 4/WG 5 (Software ergonomics and human-computer interaction). In due course a Working Draft will be prepared together with a New Project proposal for international ballot.

ISO 9241-910 – Framework for tactile and haptic interactions

This standard will provide a framework for specifying, designing and evaluating various aspects of. It will also contain general information about tactile and haptic interactions. The proposal is currently undergoing new project ballot, which closes 2007-09. ISO publication is indicated as 2010.

Development is planned by ISO/TC 159/SC 4/WG 9 – Haptic and tactile interactions.

Accessibility functions for information processing / Personal Computers

This potential standard is currently undergoing New Work Item ballot (closes 2007-07) which will also decide to which Sub Committee the project (standard) is allocated for development. The original proposal was raised in ISO/IEC JTC 1/SC 35 (User interfaces) by the Japanese national body.

A Working Draft has been developed from Japanese standard JIS X8341-5 Guidelines for older persons and persons with disabilities - Information communication and services - Part 2: Information processing equipment.

Interoperability of assistive technologies and information technologies

This potential standard is currently being discussed and developed within ISO/IEC SC JTC 1/SC 35 (User interfaces). A Working Draft is currently being prepared together with a New Project proposal for international ballot.

Guidelines for all people, including elderly persons and persons with disabilities - Marking tactile dots on consumer products

This potential standard has been proposed by the Japanese National Body and would be based upon Japanese standard JIS S 0011-2000. A Working Draft is available.

The NP ballot was approved 2007-04 and the project has been assigned to new Working Group ISO/TC 159/SC 4/WG 10 – Accessible design for consumer products. The establishment of WG 10 was approved 2007-06, and the Japanese national body will provide the convenor.

Guidelines for all people including elderly persons and persons with disabilities - Visual signs and displays - Specification of age-related luminance and its use in assessment of light

This new project was proposed by the Japanese National Body and is based upon Japanese standard JIS S 0031:2004 - Guidelines for all people including elderly persons and persons with disabilities – Visual signs and displays – Specification of age-related luminance and its use in assessment of light.

The new project was approved by international ballot (2007-04), and has yet to be assigned to a Working Group in ISO/TC 159/SC 5 – Ergonomics of the physical environment.

(ETSI) Human Factors - Specialist Task Force on M/376 - European accessibility requirements for public procurement of products and services in the ICT domain - Phase 1

ETSI is preparing a Specialist Task Force (STF) in response to Phase 1 of Mandate M/376 on European accessibility requirements for public procurement of products and services in the ICT domain. The activity will be co-ordinated between ETSI, CEN and CENELEC. The ETSI STF will produce:

An inventory of ICT products and services that are usually bought by public procurers.
A list of existing functional accessibility requirements in Member States and internationally for those ICT products and services.
In each technical area gaps will be identified where no accessibility requirements exist and suggestions will be provided for developing missing or additional requirements.
A list of existing national, European and international standards and technical specifications will be identified which might comply with those requirements
A proposal will be made for a standardization work programme for the development of requirements and award criteria that still do not exist or that are not yet standardized.

CEN/BT WG 185 - Report on Conformance schemes (second report as requested by M/376 – Phase 1)

In parallel to the ETSI STF (above) CEN is preparing a project team to produce a report under Phase 1 which “will present an analysis on testing and conformity schemes of products and services meeting accessibility requirements.”

Standards currently being developed:

ISO 9241-20 – Accessibility guidelines for information/communication technology equipment and services

Scope: This Standard addresses general guidelines for planning, designing and developing ICT products and services to ensure their accessibility for people with the widest possible range of abilities including older persons and persons with permanent or temporary disabilities (referred to as “people with special requirements”). This Standard is also intended to provide general guidelines for evaluating and purchasing ICT products and services. Information communication equipment and services include hardware and software aspects of information processing equipment, electrical communication facilities, office machines, the Internet, and others. It does not include buildings, offices or transportation.

CEN Workshop on Document Processing for Accessibility (WS/DPA)
This activity is supported by the EUAIN (European Accessible Information Network) who are funding the chairman and technical secretariat.

Objectives:

To bring together all the players in the information provision and e-publishing chain in order to achieve the critical mass significantly to enhance the provision of accessible information at a European level
To provide guidelines (a CWA = CEN Workshop Agreement) on integrating accessibility components within the document management and publishing process rather than as just a specialised, additional service.
To raise awareness and stimulate the adoption at local, regional, national and European levels of the emerging formats and standards for the provision of accessible information and to find ways of ensuring that technological protection measures do not inadvertently impede legitimate access to information by people with print impairments

Schedule:

18 July 2007 – Distribution of final draft for 60 day public consultation
18 September 2007 – Meeting to review public comments
16 November 2007 – Final workshop meeting to approve the CWA before publication.
