3 2005 Adobe Systems Incorporated. All Rights Reserved. United Kingdom: 1995 Disability Discrimination Act

ƒ The Disability Discrimination Act 1995 (DDA) makes it unlawful to discriminate against disabled people in the way in which you provide services ƒ Discrimination can take place in two ways ƒ by treating a disabled person less favourably ƒ by failing to make “reasonable adjustments” so that disabled people can make use of a service ƒ The 2001 Special Educational Needs and Disability Act (SENDA) amended the DDA to include education

4 2005 Adobe Systems Incorporated. All Rights Reserved. 1995 Disability Discrimination Act (cont.)

ƒ The Disability Rights Commission Code of Practice published February 2002 includes a definition of the term ‘service‘

ƒ http://www.drc-gb.org/uploaded_files/documents/2008_223_drc_cop_rights_of_Access.doc

ƒ A website that offers free information or a commercial product or service to the public is a ‘service’ as defined under the Act

ƒ e.g, an airline ticket booking service

ƒ Such websites must conform to web accessibility guidelines

20 2005 Adobe Systems Incorporated. All Rights Reserved. The Accessible PDF

“Document language is English” ƒ PDF maintains the visual integrity of a document

ƒ But the logical document structure may not follow the drawing order of page objects

ƒ A truly accessible PDF must unambiguously define document structure “Image of ƒ surface This is accomplished by preparation “tagging” page elements equipment” ƒ Purely visual elements must carry an alternate text description

Correctly defined reading order

21 2005 Adobe Systems Incorporated. All Rights Reserved. What do

ƒ Enable document reflow (low vision, limited mobility)

ƒ Provide a “hook” on which to hang alternative text descriptions

ƒ Make it possible to modify reading order without changing the document’s appearance

ƒ Ensure the correct interpretation of tables and interactive features such as form fields, bookmarks, hypertext links, web URLs etc.

22 2005 Adobe Systems Incorporated. All Rights Reserved. How do I make a tagged PDF?
