Good colour contrast for websites

How did you choose the colours for your last website update? Did you choose colours based on your brand logo and text or did you use the Web Content Accessibility Guidelines (WCAG) algorithm? But can the WCAG algorithm guarantee good legible colour contrasts for websites? Research by The University of Cambridge says it doesn’t. So they have developed an alternative algorithm for good colour contrast for websites.

Since January 2022, the Accessible Perceptual Contrast Algorithm proposes that legibility of text on websites is better with perceived difference than a mathematical contrast ratio. White text on strong coloured backgrounds are preferred over black text in almost all cases in the study.

In the examples above, the black text passes the WCAG contrast ratio but fails the white text. The Accessible Perceptual Contrast Algorithm passes the white text and fails the black text.

Sam Waller explains this more fully in his article, Does the contrast ratio actually predict the legibility of website text?

As a result of this work, an early working draft of WCAG 3 proposes using the new method for calculating contrast.

This is important information for choosing brand logos and text so it isn’t just something web designers should know. Many website designs are guided by brand colours so choose carefully. This information is also important for product labelling especially for online shopping.

Do web accessibility overlays work?

Accessibility Overlays - What are they & why are they so bad? - YouTube — First screen of the YouTube video

This site has a web accessibility overlay or add-in widget. It’s the circle icon next to our logo on the website. If you click on it, it has a dropdown accessibility toolbar. That’s because the platform, WordPress, isn’t inherently accessible. So like the tacked on ramp to a building, it is an afterthought. But really, it advertises that the website platform isn’t really accessible and there are good reasons why.

Website add-ons for accessibility go back to the 1990s with products like Browsealoud and Readspeaker. They added text to speech capabilities on the website. More products arrived in the market with similar aims. To the layperson these features seem beneficial, but their practical value is overstated. That’s because the people who need these features will already have the software on their devices to access the web and other software. The Overlay Fact Sheet by Karl Groves explains more:

From the overlay fact sheet

“It is a mistake to believe that the features provided by the overlay widget will be of much use by end users because if those features were necessary to use the website, they’d be needed for all websites that the user interacts with. Instead, the widget is —at best—redundant functionality with what the user already has.”

Do overlays meet compliance?

While an overlay might improve compliance in some respects, full compliance cannot be achieved using this method. That’s because the products are unable to “repair” all possible issues. In some cases, the overlay can conflict with the users software and cause problems. And ironically, some overlays are inaccessible. So that means it’s back to the programmer and designer to get it right.

The video below gives examples of overlays and graphically shows how they don’t work. You only need to look at the first three minutes to get the idea.

We all have a responsibility to make our digital information accessible. Beware any web developer who says they’ve solved the accessibility problem with an overlay or widget. Indeed, you are showing your inaccessibility by having an “accessibility” overlay and icon on your site.

Web designers might think the international web standards are sufficient. But they are not – just like the standards for access and mobility in the public domain are not enough.

By the way, CUDA uses the WordPress platform’s free version and continues to do so because we do not receive financial support for the website and want to keep it open access. As with everything universal design – it is a work in progress. “Do the best you can with what you have at the time and strive to improve next time.”

Inclusive online conference planning

Virtual and hybrid conferences have become more popular since the advent of the recent pandemic. But are they accessible and inclusive? A paper from Canada addresses the issues of inclusive online conferences. Using the recent Parks Accessibility Conference as a case study, the authors describe their experiences. As a Canadian event, they also had to consider two languages in their planning.

Some people with disability or impairment find online events less stressful than attending in person. They can avoid travel stresses and the regular access barriers. Others who find crowds and noise difficult, tuning in from home is a more comfortable. Consequently, conference planners need to take care to plan for easy access and inclusion.

And it should be for every conference, not just conferences with a disability component. However, this is a good place to begin and to learn from first hand experiences. The Parks Accessibility Conference is one such example.

Key strategies

The authors provide a list of their key strategies:

- Make visual elements accessible to attendees with vision impairment
- Make audio elements accessible to attendees who are Deaf or hard of hearing
- Avoid overstimulation for individual who are neurodiverse or with a cognitive condition
- Create ways to incorporate multi-sensory experiences remotely
- Finding the right virtual conference platform.

The planners worked with presenters to help format and organise their presentations and materials. They hosted a pre-conference session with attendees to explain how to use the various features of the online platform so they knew what to expect.

The paper reads like a story, explaining every step along the way so that others might learn from their experience. There are eight recommendations for future conferences based on what they learned. Top of the list is to include people with disability from the beginning.

The title of the paper is, Virtual Accessible Bilingual Conference Planning: The Parks Accessibility Conference.

From the Abstract

The objective of this paper is to share how our team planned and delivered a virtual conference that was fully bilingual and accessible to individuals with disabilities.

We incorporated closed captions, sign language interpretation, language interpretation (audio), regularly scheduled breaks, and a multi-sensory experience.

We describe our approaches to planning the conference, such as including individuals with disabilities in decision-making, selecting virtual conference platforms, captioners, and interpreters, and how we incorporated a multi-sensory experience.

The paper also summarizes feedback we received from our attendees using a post-conference evaluation survey and our team’s reflections on positive aspects of the conference and opportunities for improvement. We conclude by providing a set of practical recommendations that we feel may be helpful to others planning virtual accessible bilingual conferences in the future.

People with complex communication needs

See a separate paper, Supporting Communication Accessibility and Inclusion in Online Meetings for Persons with Complex Communication Access Needs. This is a Masters thesis on running online sessions for people with complex communication needs.

From the abstract

This community-based, participatory research study explores how online sessions can be designed to support complex communication access needs. The use of a community-led co-design approach resulted in a deeper understanding of the individual communication accessibility requirements, barriers, and lived experiences of persons who use AAC, within the online meeting context.

Participants (‘co-designers’) designed and took part in collaborative design sessions aimed at developing ideas for supporting communication access and inclusion throughout the process of meeting online. Through cross-community collaboration, we co-designed an open-source communication access toolkit for online meetings.

The toolkit includes accessibility guidelines with a protocol for holding accessible and inclusive online sessions; suggested accessibility features and plugins for meeting platforms; and a template for a collaborative participant notebook.

The design outcomes provide guidance to the general population on how we might ensure that online meetings of all forms are inclusive and accessible for diverse and complex communicators, as we all have a right to communicate with dignity in ways where we understand and are understood.

Making questionnaires more readable

One area of inclusion and accessibility that often gets forgotten is readability of forms and questionnaires. Academics and marketing professionals regularly use surveys to get information from specific groups of people. Within those groups will be people with varying levels of capability in terms of being able to decipher what’s on the screen or form. And it isn’t all about literacy and reading ability. It’s about the different ways people see and interpret the information. Here are some good tips for making questionnaires more readable from Alex Haagaard in Medium.

Likert Scales

Likert scales aren’t great for screen readers because they often interpret them as tables. But much depends on the design of the survey platform. Even if they are screen-readable, Likert scales can be difficult for people who are neurodiverse. People who are autistic or dyslexic struggle with visual tracking across and between rows. This creates the need to exert more brain power to focus on getting the corresponding check box.

Instead of using a Likert scale, use a series multiple choice questions to capture the same information. Creating page breaks to separate distinct sections of the questionnaire also helps with readability for everyone.

Balancing access conflicts

As is often the case, making something more accessible for one group can create problems for another. So it’s important to identify these early and eliminate or mitigate the barriers.

One solution is to provide optional comment boxes where the participant can choose whether to reply in their own words. People who want to quickly complete the questionnaire can skip this.

Haagaard takes things a step further with a suggestion to provide detailed explanations about terms and concepts at the beginning of each section. However, this is tiresome for screen readers and others might find this overwhelming. Participants can be asked at the beginning of the survey if they would like the key information repeated for each section. Those who say no can have the concise experience.

In summary, Haagaard acknowledges that it is unrealistic to assume that anything can be fully accessible to everyone. That means that there will still be occasions where an alternative means of participating is required. This might be an interview or an email.

The title of the article is Making Your Surveys More Readable. This is the third in a series on cognitively accessible survey design.

Accessible places with Google Maps

Google Maps has two new features to help us find our way and what we are looking for. Live View uses the camera in your phone to give street view directions, and the “Accessible Places” feature marks entrances with wheelchair access.

Accessible Places feature

Google Maps has expanded its “Accessible Places” feature that shows when a place is wheelchair accessible and/or stair-free. It will be interesting to see if this will encourage more places to make their businesses accessible. As we know, when it’s good for a wheelchair, it’s good for prams, bikes and trolleys.

The feature was originally launched in 2020, but it was limited to just Australia, Japan, the U.K., and the U.S. Now, the feature is available worldwide on Android and iOS.

To use this feature, turn on the “Accessible Places” setting in the Google Maps app. You will see a wheelchair icon on the business profile if it has a wheelchair accessible entrance. You will see the same icon with a strikethrough if the location is not accessible. The feature can also check to see if the location offers accessible parking, facilities, and seating.

Steepness of slopes doesn’t appear to be covered, and Google doesn’t say if their access maps are accessible.

It’s up to business owners to update their business profile to reflect whether their business is accessible. It’s unlikely Google will check whether this is true, but user feedback should keep businesses on their toes.

Live View feature

When walking around in new surroundings, Live View helps you keep your bearings. Using the phone camera, the flat map view is transformed into the street view with arrows so you know which way to head. A great plus for tourists and visitors.

With Live View, users can walk the streets using the camera on their phone and get directions on the screen. The updated version has more information such as cafes, ATMs and transit stations.

Different app developers have tried their hand at creating access maps, but Google brings many features together on the one screen. However, access for wheelchair users does not guarantee access for everyone, and it doesn’t cover all disabilities. It also doesn’t say how welcome people with disability will feel. Nevertheless, it is a good start and Google will continue to improve. The next thing is finding places where you can hear each other talk.

The Metaverse: inclusive and accessible?

The concept of the Metaverse is a continuous online 3D universe that combines multiple virtual spaces. It’s the next step on from the internet. It means users can work, meet, game and socialize in these 3D spaces. We are not quite there yet, but some platforms have metaverse-like elements. Video games and Virtual Reality are two examples. So, we need to keep a careful watch on developments to make sure the Metaverse is inclusive and accessible.

Another term for the Metaverse is digital immersive environments. It sounds science fiction, but this fiction is becoming a fact. Someone is designing these environments, but are they considering equity, diversity and inclusion? Zallio and Clarkson decided to tackle this issue and did some research on where the industry is heading.

Several companies are involved in the development of digital immersive environments. So before they get too far in development it’s important to define some principles for the design of a good Metaverse. Zallio and Clarkson came up with ten principles that embrace inclusion, diversity, equity, accessibility and safety.

10 Principles for designing a good Metaverse

is open and accessible
is honest and understandable
is safe and secure
is driven by social equity and inclusion
is sustainable
values privacy, ethics and integrity
guarantees data protection and ownership
empowers diversity through self-expression
innovates responsibly
complements the physical world

Their paper is insightful and provides some important areas for discussion and research. We need developers to consider the essentials of inclusion, diversity and accessibility. Zallio and Clarkson advise that designers can learn from the past to reduce pitfalls in the future. As the Sustainable Development Goals say, “leave no-one behind”.

Diagram showing the 10 principles for designing a good Metaverse.

The title of the paper is Designing the Metaverse: A study on Inclusion, Diversity, Equity, Accessibility and Safety for digital immersive environments.

Synopsis of the paper

1. The Metaverse appears as the next big opportunity in the consumer electronics scenario.

2. Several companies are involved with its development.

3. It is extremely important to define principles and practices to design a good Metaverse.

4. Qualitative research pointed out to challenges and opportunities to design a safe, inclusive, accessible Metaverse that guarantees equity and diversity.

5. Ten principles for designing a good Metaverse embrace inclusion, diversity, equity, accessibility and safety.

From the abstract

The Metaverse is shaping a new way for people interact and socialise. By 2026 a quarter of the population will spend at least an hour a day in the Metaverse. This requires consideration of challenges and opportunities that will influence the design of the Metaverse.

A study was carried out with industry experts to explore the social impact of the Metaverse through the lens of Inclusion, Diversity, Equity, Accessibility and Safety (IDEAS). The goal was to identify directions business has to undertake.

The results indicated the nature of future research questions and analysis to define a first manifesto for Inclusion, Diversity, Equity, Accessibility and Safety in the Metaverse.

This manifesto is a starting point to develop a narrative, brainstorm questions and eventually provide answers for designing a Metaverse as a place for people that does not substitute the physical world but complements it.

City Access Map

CITY ACCESS MAP is a web application that shows how cities across the world are doing in terms of accessibility. It’s open source and covers any urban area with more than 100,000 residents. It computes walking accessibility down to the block level. It’s a tool for almost anyone who has an interest in cities that have access to services within a 15 minute walk.

The CITYACCESSMAP is interactive and shows the differences in cities across the globe. For example, it shows that Bogota, Colombia is one of the most accessible cities. Orlando USA on the other hand is one of the least accessible. France is generally accessible with many cities reaching high levels of accessibility.

Australia is represented by Brisbane, Sydney, Melbourne and Adelaide. Searching by city brings a close up view of the suburbs. In Sydney, it shows good accessibility in and around the CBD. However, as expected as you move to outer suburbs accessibility reduces considerably.

It should be noted that the term “accessibility” mainly refers to access to services rather than an accessible built environment. The tool is worth investigating as a planner and administrator in any field. If nothing else, it is interesting to see how countries compare.

For IT people wanting to know the detail of the map design there is more information in a separate section. You can download processed data for any city in the application.

The scientific research is also available and you can contribute to the project by contacting Leonardo Nicoletti.

Universal design and perfection

A universal design approach to a project often means doing the best you can with the knowledge, skills and resources to hand. Each time you have a design project, make it more accessible and inclusive than the last. Universal design is not about perfection, or perfection for absolutely everyone. It is an ongoing iterative process.

The notion of perfection reinforces the perspective that accessibility is hard.

A blog post from CanAxess discusses the issue of perfection in digital and web design. Using the example of two people, a celebrity chef, and a special forces soldier, the article discusses “the perfection millstone around the neck”.

If digital designers have a mindset of expecting absolute perfection they will reinforce the idea that accessibility is hard. For example, headings might be incorrectly rendered on a page. For designers this is unforgivable and a “slight on those users who need that support the most”. The risk is that designers will give up and stop trying to improve digital accessibility. And then there is the anxiety, procrastination and fear of falling short.

Having high standards is a good thing, but it needs to be balanced otherwise it makes it hard to get started on a project. So, at these times, “good enough is good enough”. The advice from the blog post is to do better than yesterday and do it well.

Google spells out accessible, inclusive, usable

It would be good if all designers took their lead from the likes of Apple and Google: inclusion, accessibility and usability are about the design process. Apart from clearly explaining how these terms are linked and can be used together, Google spells out accessible, inclusive and usable in a half hour video

Infographic showing three groups of disability: permanent, temporary and situational. From Microsoft. — Microsoft infographic: Permanent, temporary, situational disability

The video also has some tips and tools for designers and shows how three different users have the same need: a man with a mobility disability (permanent), a boy with a broken arm (temporary) and a woman with an armful of shopping (situational). Microsoft designed an infographic to illustrate the point.

Individual situations might be different but they all have the same need for accessibility. And people have the same goals they want to achieve regardless of their situation.

This instructional presentation is aimed at an audience interested in designing apps, particularly the second half of the video. However, the messages in the first half can be applied to other design disciplines.

Website cookie banners: barriers to access?

Some people think that people who are blind can’t use websites or smartphones because they can’t see the screen. This is not true of course because they use screen reader software to read out the content of the webpage. However, even on a reasonably accessible website, cookie banners are barriers to access to the very first page.

Many websites have accessible features, but they are not necessarily linked up. The popup cookie banner can prevent some users from accessing the website entirely.

Clive Loseby’s Tedx talk explains that despite legislation for online accessibility, very few websites meet basic access standards. You can check your easily by doing what people with low vision and people with screen readers do. They use the keyboard and not the mouse. Go to your home page and use the Tab key. Does it progress through the menu or navigation tabs?

It is a legal requirement in most countries to have accessible websites – the guidelines and standards have been around for more than 20 years. What is taking so long? Clive Loseby explains basics and how every organisation or business is missing out on customers.

Some websites use popup banners to advertise something and others use scrolling images as well. These have a similar effect to the cookie banners.

A reminder about attitude

Some of the responses to the talk in the comments section are not positive and in some cases almost abusive. While all YouTube videos get their share of negatives, it is still a reminder that ableism is alive and well.
