If accessibility is on the agenda in a web project, then the question often arises, which step should be the first step. Barrier-free web design is by no means trivial. The following tips are intended to help you get started in this topic.
Which guidelines can I use?
The Web Content Accessibility Guidelines 2.0 provides a comprehensive description of the requirements to be satisfied in 61 success criteria. The WCAG 2.0 is a recommendation of the World Wide Web Consortium and was adopted in 2008. The guidelines also specify the rules of conformity – compliance with all the requirements of the Directive.
In most countries, various regulations with heterogeneous criteria apply. The “Barrier-free Information Technology Ordinance 2.0” (short: BITV 2.0), which is relevant for the federal administration, contains not only an excerpt from WCAG 2.0 but also further requirements for easy language and sign language.
The orientation to the Web Content Accessibility Guidelines (WCAG 2.0) allows a reliable achievement of conformity, not least because of the detailed documentation. Start there with the lowest compliance level. The use of a good digital agency in Dubai will help you become compliant.
Which users should reach my offer?
Accessibility is about people with disabilities – a very heterogeneous target group. Before implementing a barrier-free web design, you should therefore consider the working methods and specific requirements of the various user groups:
- Blind users use so-called screen readers to convey screen content using non-visual output devices (acoustically via voice output or tactile via a so-called “braille display”). Screenreaders, in turn, rely on the accessibility tree of an operating system (the accessibility tree is an interface to the operating system, where applications such as browsers provide information about the user interface, where they are then fetched and processed by screen readers).
- Important aspects for the web development for the visually impaired are – in addition to the limited perception of visual content in particular the adjustment of the screen settings and the use of magnification systems.
- Some users with physical limitations cannot use the mouse pointer (or keyboard). However, it is important for the web design that the usability of all functions is guaranteed by keyboard.
- People with learning disabilities may need u. a. Easy language. Unfortunately, there are hardly any requirements for this in the corresponding web standards.
For deaf users, acoustic information must also be provided in text form. The translation of content in sign language is required by the web standards only for audio content in videos. The BITV 2.0 also specifies that homepages must include some introductory information in sign language.
