An introduction into web accessibility, including the groups of people with disabilities affected by an inaccessible web site, the relevant legal and Government requirements and litigation in the area. Video demonstrations of various assistive technologies are shown, including a screen reader, thumb switch and onscreen keyboard.
Accessibility during a web site build
Incorporating accessibility into your web site build is important and can often mean the difference between an accessible and an inaccessible site at launch. Specific stages require accessibility intervention, including design, template, and final site launch. Suitable tasks and training is also covered.
Interactive maps are notoriously difficult to make accessible: in fact when it comes to accessibility for people with vision impairments, often it is assumed that maps cannot be made accessible. Gian Wild talks about the requirements for a fully accessible interactive map and how it can be accessible for all people with disabilities.
Instead of focusing on the accessibility of PDFs, Gian talks about how PDFs are used in the real world. Why do people upload so many PDFs? Gian talks about the main reasons for PDF usage – and the excuses people give as to why PDF must be used. Gian then talks about why PDFs are not the best format for the web, and when given a choice, what people really prefer.
Harvard and MIT have been sued by the National Association for the Deaf (supported by the Department of Justice) for lack of accurate closed captioning on their videos. However, the case also involves the inaccessibility of the video players. In our testing, we found only two accessible video players, and neither of them were the large commercial players that most organizations use.
Gian Wild talks about what makes a video player accessible, with examples.
Social media accessibility is an incredibly important tool in modern society. It is not just the young who access social media, with close to 30% of people over the age of 65 interacting on social networking sites, and 50% of people aged 50 – 64. As the percentage of recruiters who use LinkedIn is now 95%, social media is becoming an essential part of negotiating the current working environment.
The main reason why social media is not accessible is that social networking sites and apps are almost continually refreshed. Facebook sometimes changes twice a day. This, coupled with a lack of a formal testing process, means that what may be accessible today may be literally gone tomorrow.
Gian Wild goes through the accessibility issues of each of the four main social media sites (Facebook, Twitter, YouTube and LinkedIn) and discusses ways that you can make sure your social media content is accessible.
Carousel. Slideshow. Slider. Whatever you call them, they’re ubiquitous on organizational home pages across the web. And almost all of them are inaccessible. Gian goes through the requirements for an accessible slideshow, including the ability to pause with the mouse and keyboard, controls, contrast and how to make sure a carousel is accessible to screen reader users.
Unfortunately, when developing WCAG2, the Working Group did not envision the current world where mobile is almost ubiquitous. For example, on a mobile device there is no continual access to a keyboard (unless someone is using it as an add-on to the device – or using a Blackberry Classic). WCAG2 requires that all content be accessible to the keyboard interface, but it does not require that all content be accessible to a mouse or to a touchscreen user – which is essential on a mobile device. Gian Wild talks about the unique accessibility issues on a mobile site and mobile app, including hover traps, VoiceOver swipe traps and zoom traps.
