This document provides an introduction to web accessibility. It begins by addressing some common misconceptions about accessibility, noting that it aims to accommodate people with a wide range of disabilities, not just visual impairments. The document emphasizes that accessibility is important for both ethical and legal reasons, and that inclusive design benefits all users. It then outlines key web accessibility guidelines from the W3C, providing examples of how to make content more accessible through proper semantic markup and alternative text. The conclusion stresses that accessibility is an essential consideration for web development.

Accessibility
The web is about information sharing. Why make it hard for users to access your content. Release your site from bad building practices, make it equal access for all and get SEO benefits for free.
Get through to the disabled community
By breaking down disability barriers you open up your content to a wider community currently 600,000+ in NZ.
There are definite dos and don’ts when it comes to building for the disabled. Learn what works for them.
I Am the LAAW! (Lean Accessibility Audit Workshops)Michael Ryan
Fitting accessibility into an agile development cycle can be challenging. Often accessibility specialists are spread thin across agile squads and they have to deliver quickly into multiple sprint cycles.
To meet the demand I looked to Lean UX principles and developed The Lean Accessibility Audit Workshop (LAAW). LAAW has two goals 1) detect accessibility problems quickly and 2) spread the accessibility knowledge. This is accomplished by training members of agile squads on accessibility basics, evaluation methods and tools. The training evolves into an accessibility audit as squad members collaboratively capture, share and prioritize findings. The LAWW method compresses a 6-8 week evaluation process into a 2 weeks process while training squad members to detect and avoid accessibility issues in the future. And it can be pretty fun.
Web accessibility refers to the inclusive practice of removing barriers that prevent interaction with, or access to, websites by people with disabilities. When your website is inaccessible, research shows you could be excluding up to 20 percent of your visitors from interacting with your content and functionality. If your university website is inaccessible, you could be preventing access to education, student services, and more.
When your website is accessible, everyone can consume your information freely. Visually-impaired users can visit your website using a screen reader. Those who can’t use a mouse can navigate your site using a keyboard or other input device.
While creating accessible websites involves every step, including design and content, the foundation for good accessibility starts with good markup. Join my workshop to learn more about accessibility and how to program a high-quality user experience that is inclusive and beneficial to all.

WCAG is supposed to give us a reasonably objective way of saying whether or not the sites we are building/auditing are "accessible" (to a particular baseline). However, they are only as useful as our understanding and interpretation of the guidelines' normative text. And, of course, it is not perfect - with some omissions, handwaving, and straight-up loopholes. So where does this leave developers and auditors?
In this talk - a reprise of a previous talk, now updated to cover new SCs from WCAG 2.2 - Patrick may not have all the answers, but he'll have a good rant around the subject anyway...

WAI-ARIA An introduction to Accessible Rich Internet Applications / JavaScrip...Patrick Lauke
Vanilla HTML is limiting and boring. Our clients demand highly engaging and interactive web experiences. And wouldn’t you know, with just a bit of HTML and JavaScript we can craft amazing custom controls, widgets and effects that go far beyond the confines of traditional static markup. But how can we ensure that these custom experiences are both understandable and usable for people with disabilities, and in particular those using assistive technologies such as screen readers?
In this talk, we will look at the basics of making some common custom-built components accessible - covering how browsers and assistive technologies interact, the limitations of HTML, and how ARIA can help make interactive experiences more accessible. In addition, we will explore some of the recent additions in ARIA 1.1, as well as some particular challenges when it comes to traditional ARIA patterns and assistive technologies on mobile/tablet/touch devices.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.
Gopinath Rebala
Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.
Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Web Accessibility - an introduction
Patrick H. Lauke
SBS briefing session - 16/11/2006
2. 16/11/2006 2
Introduction
What we’ll cover today:
• some of the misconceptions about accessibility
• reasons why accessibility is important
• highlight some web accessibility guidelines
Q&A at the end, but please shout out any questions.
3. 16/11/2006 3
So why am I here?
• involved in web since early 90s
• University webmaster since 2001
• responsible for writing and enforcing web strategy, standards
and guidelines for UoS
• involved in global discourse on accessibility
• WaSP (Web Standards Project) Accessibility Task Force
4. 16/11/2006 4
Some misconceptions
What is accessibility?
“making sure our web site works for the blind…”
There is a wide range of disabilities:
• visual impairments
• auditory impairments
• mobility impairments
• cognitive disabilities
5. 16/11/2006 5
Some misconceptions
Why bother?
Marketing executive:
“such a small market is not worth the hassle”
Web designer:
“no time to create a separate accessible site”
Site owner:
“blind people won’t be using my web site”
6. 16/11/2006 6
Some misconceptions
Marketing executive:
“such a small market is not worth the hassle”
It is estimated that there are 7 million disabled people
in the UK and that around 19% of the working age
population has some form of disability.
Source: Disability Rights Commission – Disability briefing January 2004
7. 16/11/2006 7
Some misconceptions
Web designer:
“no time to create a separate accessible site”
In majority of cases, no need for special “disabled only access”
site.
• Inclusive design, not segregation
• Separation of content and presentation, using web standards,
structural markup: single site, accessible to all
• Accessibility included in planning stage, not as an afterthought
• “Text only” is not a solution
8. 16/11/2006 8
Some misconceptions
Site owner:
“blind people won’t be using my web site”
Accessibility not just about the blind, but…
A possible scenario: visually impaired customer buying
photographs or paintings for a sighted relative?
9. 16/11/2006 9
Legal requirements
If the ethical / moral and financial reasons were not enough, there are
legal requirements:
• UK - Disability Discrimination Act 1995
provision of goods and services
• Australia – Disability Discrimination Act 1992
• USA – Americans with Disabilities Act
• USA – Section 508 of Rehabilitation Act
procurement policy for federal government agencies
Other countries have similar legislation.
Cases are being brought to court: SOCOG, RNIB,
Ramada/Priceline…
10. 16/11/2006 10
Legal requirements for Education
Original Disability Discrimination Act 1995 explicitly excluded
Public Transport and Education
Special Educational Needs and Disability Act 2001 (SENDA)
removed exemption, effectively became part IV of the DDA.
“Disabled students not to be substantially disadvantaged”
11. 16/11/2006 11
Access for all
More importantly
• Accessibility is not just about users with disabilities
• Provisions and changes made for accessibility can benefit all users
“Real world” example: access ramps
With regards to web:
• Benefits to users of alternative browsing devices (PDAs, web phones, etc)
• Not a permanent disability, but “situational” – library PC, loud environment, etc
• “Silver surfers”
Crossover between usability and accessibility
13. 16/11/2006 13
W3C Guidelines
So…what’s a web designer to do?
World Wide Web Consortium (W3C) committed to accessibility
"The power of the Web is in its universality. Access by everyone
regardless of disability is an essential aspect.“
Tim Berners Lee, W3C Director
W3C Web Accessibility Initiative (WAI) produced Web Content
Accessibility Guidelines (WCAG)
14. 16/11/2006 14
W3C Guidelines
WCAG 1.0, 5 May 1999
14 guidelines (general principles), broken down into checkpoints.
Checkpoints categorised into 3 priority levels
• [Priority 1] A Web content developer must satisfy this checkpoint.
• [Priority 2] A Web content developer should satisfy this checkpoint.
• [Priority 3] A Web content developer may address this checkpoint.
15. 16/11/2006 15
W3C Guidelines
1. Provide equivalent alternatives to auditory and visual content.
2. Don't rely on color alone.
3. Use markup and style sheets and do so properly.
4. Clarify natural language usage
5. Create tables that transform gracefully.
6. Ensure that pages featuring new technologies transform gracefully.
7. Ensure user control of time-sensitive content changes.
8. Ensure direct accessibility of embedded user interfaces.
9. Design for device-independence.
10. Use interim solutions.
11. Use W3C technologies and guidelines.
12. Provide context and orientation information.
13. Provide clear navigation mechanisms.
14. Ensure that documents are clear and simple.
Not going to go through all, but give a few examples
16. 16/11/2006 16

3) Use markup and style sheets and do so properly (cont.)
<h1>This is a heading</h1>
<p>Blah blah blah</p>
<h1>This is another heading</h1>
<p>Blah blah blah</p>
<h2>A sub-section</h2>
<p>Blah blah blah</p>
• Machine-readable.
• Convey meaning and structure, not just visual appearance.
• Cfr MS Word and screen readers.
• “But the headings look ugly…” – use CSS
Outline:
•This is a heading
•This is another heading
–A sub-section

6) Ensure that pages featuring new technologies transform gracefully
• Plugin technologies: Java, Flash, Shockwave.
• Scripting: VBScript (IE only!), reliance on javascript.
Worst case: navigation or other essential page feature.

WCAG examples
6) Ensure that pages featuring new technologies transform gracefully
Javascript popups – what happens when JS is off/unavailable?
<a href=“#” onclick=“window.open(‘foo.html’)”>bar</a>
Can be made accessible (fallback mechanism):
<a href=“foo.html” onclick=“window.open(this.href); return
false;”>bar</a>

Automated validators
The infamous “Bobby”…(now WebXact http://webxact.watchfire.com/ )
• Automated accessibility checkers are dumb.
• “Bobby” and co. are just a tool and do not replace human
checks.
• False positives, false negatives.

All my images have an ALTernate text of “image”…is that
accessible?

Conclusion
Hopefully, what you’ll take away from this presentation:
• Accessiblity not just about “the blind”
• Moral, financial and legal reasons to ensure web sites are
accessible
• Accessibility can benefit all users
• W3C WAI WCAG and some examples
Worth noting: accessibility not about rote mastery of a few
guidelines. Many cases where there is no one single solution –
requires judgement and compromise.
