DIGITAL UNIVERSITY PROJECT

Covering

• Background

• Legal Frameworks (students and staff)

• Content Management Solution

• uPortal and Accessibility

• Conclusions


The Digital University Project

• Planned over the summer of 2001

• Senior Management buy-in and support

• Flexible structure with cross-institutional steering group

• Two initial development strands

– Institutional web portal

– Web content management


First Targets: Students and Staff• Core database applications - Ingres

• Web based email client – IMP

• Library systems - Innovative

• Staff Intranet - home-grown, PERL etc

• VLE/LMS – BlackBoard L1 + Merlin

• External applications - identification


Accessibility: Legal Frameworks• United States

– Americans with Disabilities Act– Section 504 & 508 Rehabilitation Act– Section 255 Telecommunications Act

• United Kingdom– Disability Discrimination Act 1995– Special Educational Needs & Disability Act 2001

• European Union– European Employment Directive (by 2006)

• Australia– Disability Discrimination Act 1992– Telecommunications Act 1997


In the US…• ADA: right to be able to access and use any facilities

and programs available to other members of the public. • Section 255 of the Telecoms Act: manufacturers of telecom

products and services make them accessible to people with disabilities whenever "readily achievable".

• Rehabilitation Act – Section 504 “reasonable adjustment” in the

workplace– Section 508 of the Rehabilitation Act: Federal Agencies

develop, procure, maintain, or use only those electronic and IT systems which comply with a set of accessibility standards, unless this places an "undue burden" on the Agency.


US: WAI/WCAG and s 508

• WCAG Level A (Priority 1) conformant site needs additional work in the 5 areas of– Scripts

– Applets

– Forms

– Navigation

– Timed response feedback

To be s 508 conformant


US: WAI/WCAG and s 508

• S 508 conformant site needs additional work in the 4 areas of

– Auditory description of visual track

– Identify changes in natural language of text

– Equivalents for dynamic content

– Clarity of language

To be WAI/WCAG Level A (Priority 1) conformant


US case experience

• Access Now/Gumson vs Southwestern Airlines

• Ruling that ADA does not apply to the internet but to specified physical spaces

• Specific rejection of WAI/WCAG specs as not "a generally accepted authority."


In the UK

• Special Educational Needs & Disability Act 2001 applies Disability Discrimination Act 1995 to education from Sept 2002

• Institutions should make “reasonable adjustments” enabling access to “student services”

• Disabled students should not be placed at “substantial disadvantage”

• Anticipatory legislation


BUT …

“Less favourable” treatment may be justified:

• Maintain academic standards

• Prohibitive cost

• Affects the interests of other students

• Impacts on health and safety


In the European Union …

• Community Institutions must “take account” of needs of disabled peopleAmsterdam Treaty - Declaration 22

• “Public sector web sites … must be designed to be accessible to ensure that citizens with disabilities can access information and take full advantage of the potential for e-government.“eEurope Action Plan, Feira Council, June 2000

• EED: "reasonable accommodation" for disabled employees by 2006


EU: accessibility & education• Widening participation and Design-for-All

• European Union/European Commission Actions

– Tendering criteria modified to include e-accessibility

– Framework Programme VI modified

– Promotion via WAI-DA project

• Legislative variance across member states

• ESOs identify standards as basis for legislation


In Australia• Disability Discrimination Act 1992

– Encourages organisational “Disability Action Plan”

• Telecommunications Act 1997– Universal Service Obligations include equipment

for disabled people

• Funding for consumer groups such as TEDICORE (Telecommunications and Disability Consumer Representation)

• Australian Communications Industry Forum


Australian case experience

• Scott vs Telstra 1995• Failure to provide a text telephone ruled

discriminatory

• Maguire vs SOCOG 2000• Sections of web site for Sydney Olympics

inaccessible ruled discriminatory


Summary

• UK and EU likely to reference WAI/WCAG Priority Levels

– In legislation (EU)

– In cases (UK)

• US explicit rejection of WAI/WCAG specs

• Australian framework (with active consumer group involvement) actively promoted by EU


Content Management: Resolving Chaos

• The Web: it’s not amateur hour anymore

• Web tools by Heinz – 57 varieties of editor

– Technical support nightmare

– Human Resource nightmare

• Accessibility “test case” – any volunteers?

• Aggregating web pages through portal: GIGO


Content Management: Solutions• Solution for sites and portal channels

• Caveat: 2 years ago, but watching…

• Almost universally expensive/overpriced

• Frequently inflexible

• Not designed for use by HEI


Content Management: Technology• Not “Build or buy, but build and buy”• db solution utilising current licences• Edit basic content within secure web page• Design templates

– XHTML output (now) > XSLT (future)– base design – WAI/WCAG Priority 1– high contrast design – WAI/WCAG Priority 3

• Support rudimentary, but flexible workflow


Content Management Process

• Sensitivity to cultures of departments

• “What do you need to do?”

• Information design & architecture first

• Flexible “toolkit” approach

• Clear responsibilities and ownership

“Everything should be made as simple as possible, but no simpler.”


uPortal and Accessibility: Goals• To create a portal that enables all users

to have equal access to information

• As far as possible enable use without Assistive Technologies (direct access)

• Facilitate access for Assistive Technologies (compatible access)

• Address visual impairments/motor disabilities first


Design

• uPortal provides flexibility

• Look and feel

– skins for different visual impairments

• Structural layout

– how the content is presented

• Simplify the portal design


Tools/Testing

• Automated tools to check conformance– Bobby – check for WAI/508

• (http://bobby.watchfire.com)

– A-Prompt, LIFT

• Test with assistive technology– e.g. screen readers

• Test with users


Look and feel

• Update the CSS and create new graphics

• Two skins

– base – University visual identity

– high contrast – Visual impairments

• Other issues

– font sizes


New skins – base version


New skins - High contrast


Layout

• Use tab/column default scheme

• edit nested-tables.xsl– webpages/stylesheets/org/jasig/portal/layout/tab-column/nested-

tables

• 4 main sections

– Header, Navigation, Content and Channel


• Aggregate all the functionality into one visual layer

• Simplify by removing the tab graphics and login channel

• Screen reader has immediate access to navigation

• Keyboard shortcuts using accesskey attribute

Header & Navigation


Header & Navigation – High contrast• nested-tables.xsl checks the skin

<xsl:if test="$skin='hull'">

…. </xsl:if>

<xsl:if test="$skin='hullac'">

<div class="uportal-text-ac2">THE UNIVERSITY OF HULL</div>

<div class="uportal-text-ac">port.hull.ac.uk</div>

</xsl:if>


Content


Channel


Results• Work in progress

– can be used without assistive technology– access for AT– skin for visual impairment– enabled some keyboard access

• Outstanding – To pass WAI/WCAG Priority 2 needs to

• use a public identifier in a DOCTYPE statement• warn users about pop-up windows or when changing the active window

– Base version also needs to • use relative sizing and positioning (% values) rather than absolute (pixels)

– Section 508• Passes

– Finer grained user choices


Issues for portal implementation• Grey areas:

– Resources and links external to institution

– Distance learners

• Aggregated systems presented via portal

– Portal as conformant “wrapper”?

– Presentation oriented web services (WSRP)


Practically …

• Don’t second guess “Reasonable Adjustment/etc” – Use automated conformance tools

– BUT, test with real users

– AND test with variety of assistive technologies

• Document every step…

• Access All Areas (http://www.techdis.ac.uk/accessallareas/)
