1	Why Bother with Accessibility?	Web accessibility (known in other fields as inclusive design or universal design) is the degree to which a website is available to as many people as possible. Accessibility is most often used to describe how people with disabilities can access the web. How we approach accessibility In the web community, there’s a surprisingly inconsistent approach to accessibility. There are some who are endlessly dedicated to accessible web design, and there are some who believe it so intrinsic to the web that it shouldn’t be considered a separate topic. Still, of those who are familiar with accessibility, there’s an overwhelming number of designers, developers, clients and bosses who just aren’t that bothered. Over the last few months I’ve spoken to a lot of people about accessibility, and I’ve heard the same reasons to ignore it over and over again. Let’s take a look at the most common excuses. Excuse 1: “People with disabilities don’t really use the web” Accessibility will make your site available to more people — the inclusion case In the same way that the accessibility of a building isn’t just about access for wheelchair users, web accessibility isn’t just about blind users and screen readers. We can affect positively the lives of many people by making their access to the web easier. There are four main types of disability that affect use of the web: Visual Blindness, low vision and colour-blindness Auditory Profoundly deaf and hard of hearing Motor The inability to use a mouse, slow response time, limited fine motor control Cognitive Learning difficulties, distractibility, the inability to focus on large amounts of information None of these disabilities are completely black and white Examining deafness, it’s clear from the medical scale that there are many grey areas between full hearing and total deafness: mild moderate moderately severe severe profound totally deaf For eyesight, and brain conditions that affect what users see, there is a huge range of conditions and challenges: astigmatism colour blindness akinetopsia (motion blindness) scotopic visual sensitivity (visual stress related to light) visual agnosia (impaired recognition or identification of objects) While we might have medical and government-recognised definitions that tell us what makes a disability, day-to-day life is not so straightforward. People experience varying degrees of different conditions, and often one or more conditions at a time, creating a false divide when you view disability in terms of us and them. Impairments aren’t always permanent As we age, we’re more likely to experience different levels of visual, auditory, motor and cognitive impairments. We might have an accident or illness that affects us temporarily. We might struggle more earlier or later in the day. There are so many little physiological factors that affect the way people interact with the web that we can’t afford to make any assumptions based on our own limited experiences. Impairments might be somewhere between the user and the website There are also impairments that aren’t directly related to the user. Environmental factors have a huge effect on the way people interact with the web. These could be: Low bandwidth, or intermittent internet connection Bright light, rain, or other weather-based conditions Noisy environments, or a location where the user doesn’t want to disturb their neighbours with sound Browsing with mobile devices, games consoles and other non-desktop devices Browsing with legacy browsers or operating systems Such environmental factors show that it’s not just those with physical impairments who benefit from more accessible websites. We started designing responsive websites so we could be more future-friendly, and with a shared goal of better optimised experiences, accessibility should be at the core of responsive web design. Excuse 2: “We don’t want to affect the experience for the majority of our users” Accessibility will improve your site for all your users — the usability case On a basic level, the different disability groups, as shown in the inclusion case, equate to simple usability goals: Visual – make it easy to read Auditory – make it easy to hear Motor – make it easy to interact Cognitive – make it easy to understand and focus Taking care to ensure good usability in these areas will also have an impact on accessibility. Unless your site is catering specifically to a particular disability, where extreme optimisation is most beneficial, taking care to design with accessibility in mind will rarely negatively affect the experience of your wider audience. Excuse 3: “We don’t have the budget for accessibility” Accessibility will make you money — the business case By reducing your audience through ignoring accessibility, you’re potentially excluding the income from those users. Designing with accessibility in mind from the beginning of a project makes it easier to make small inexpensive optimisations as part of the design and development process, rather than bolting on costly updates to increase your potential audience later on. The following are excerpts from a white paper about companies that increased the accessibility of their websites to comply with government regulation. Improvements in accessibility doubled Legal and General’s life insurance sales online. Improvements in accessibility increased Tesco’s grocery home delivery sales by £13 million in 2005… To their surprise they found that many normal visitors preferred the ease of navigation and improved simplicity of the [parallel] accessible site and switched to use it. Tesco have replaced their ‘normal’ site with their accessible version and expect a further increase in revenues. Improvements in accessibility increased Virgin.net sales by 68%.

Excuse 4: “Accessible websites are ugly” Accessibility won’t stop your site from being beautiful — the beauty case Many people use ugly accessible websites as proof that all accessible websites are ugly. This just isn’t the case. I’ve compiled some examples of beautiful and accessible websites with screenshots of how they look through the Color Oracle simulator and how they perform when run through Webaim’s Wave accessibility checker tool. While automated tools are no substitute for real users, they can help you learn more about good practices, and give you guidance on where your site needs improvements to make it more accessible. Amazon.co.uk It may not be a decorated beauty, but Amazon is often first in functional design. It’s a huge website with a lot of interactive content, but it generates just five errors on the Wave test, and is easy to read under a Color Oracle filter.

Despite the complexity of the design, it gets an outstanding zero errors on the Wave test, and is still readable under a Color Oracle filter.

It only gets one error on the Wave test, and looks fine under a Color Oracle filter.

However, SoundCloud only gets one error on the Wave test, and the colour contrast holds up well under a Color Oracle filter.

Your types of content and interactions will dictate one set of constraints. Your users’ needs and goals will dictate another. In broad terms, web design as a practice is finding the equilibrium between these constraints. And then there’s just caring. The web as a platform is open, affordable and available to many. Accessibility is our way to ensure that nobody gets shut out.	2013	Laura Kalbag	laurakalbag	2013-12-10T00:00:00+00:00	https://24ways.org/2013/why-bother-with-accessibility/	design
