Anyone interested in optimal colours for web and phone might be interested in a project that came out of a colour matching game app. The game is based on colour perception. Feedback data showed designers how people perceive colour. With the help of academics they began to analyse the data in meaningful ways. Preliminary analysis indicates there is a variation across countries. For example, Norwegians were better at colour matching than Saudi Arabians. Singaporeans struggled to identify greens, and Scandinavians did best with red-purple hues. Research papers are to follow which could lead to more inclusive colour choices. The article concludes,
“But the fruits of the project live on in open source. A generic version of Jose’s tools to query the Specimen dataset are hosted here on github. My greatest hope is other researchers find and make use of what was gathered, and that other designers and engineers consider leveraging play in unexpected ways”.
An excellent resource from Ontario, Canada on accessible graphic design. It’s everything you wanted to know but didn’t know how to ask. Graphic design covers creative design, visual communications, applied design and technology sectors. So the guide covers typography, digital media, web accessibility, Office documents, accessible PDFs, print design, environmental graphic design, colour selection and more. It’s written for an easy read and has a logical structure. At the end is a list of publications, links to websites and tools to help.
Six different posters help designers make online services accessible in government and elsewhere. They cover low vision, deaf and hard of hearing, dyslexia, motor disabilities, people with autism and users of screen readers. The posters are simple and this is what makes them effective. Basically they act as visual prompts to designers rather than offering technical know-how. You can download each of the postersfrom the UK Government website. There’s other useful information and links too. Also available in 17 languages.
Colour vision deficiency or colour blindness affects around 10 per cent of the population. But each person varies in what colours they can see, which is why it is not “colour blindness”. So what colours are best if you want all readers to enjoy colours on your website? Colour choice is not just a matter of making it look good – it can affect the readability of text and graphics as well.
A small qualitative study looked at two websites to assess their readability and usability by people who have colour vision deficiency. The researcher analysed body text, background and links and found they had an affect on the usability of the websites. The research included designing two websites and then testing them with survey participants. The results should be read in conjunction with the methodology otherwise it won’t make sense. The conclusion section does not provide the specific outcomes.
The title of the article is, The effects of color choice in web design on the usability for individuals with color-blindness. This is a Masters theses.
Here are some tips for making social media more accessible, courtesy the Australian Network on Disability blog post which has more detail for each heading. The first in the list is a must. Posting a funny sign or a clever quotation can’t be read by everyone. Make sure the text is part of the post. A very useful webpage with a good deal of information – bookmark it for future reference.
Microsoft has updated their Inclusive Design Toolkit. It’s a comprehensive guide that focuses on design principles that can be applied in any design situation. Their key advice is to recognise exclusion, solve for one and extend to many, and learn from diversity.
You can download the toolkit in sections. It also includes several case studies in the form of video clips. These are not all about websites or phone apps either. They have been chosen to help inspire all kinds of designers to think about diversity. I liked the one about Antoine, the dancer.
Microsoft’s definition of inclusive design is a methodology, born out of digital environments, that enables and draws on the full range of human diversity. Most importantly, this means including and learning from people with a range of perspectives.
Microsoft’s design principles: Exclusion happens when we solve problems using our own biases. As Microsoft designers, we seek out those exclusions, and use them as opportunities to create new ideas and inclusive designs.
A very useful design guide for students and practitioners alike.
It’s one thing to talk about colour blindness, but it is quite another to see what it looks like to the 6-10 percent of the population that have colour vision deficiency. Axess Lab has produced an excellent set of successes and failuresusing real life examples of colours used by web designers. These examples provide really good guidance for anyone involved in web content and design, as well as printed material. The blog page has links to more information. There is a nice pic of what a football field looks like to someone who can’t see red and green – so it’s not all about the web – it’s all around us as the picture shows. If you want to see more on this topic see ColourBlindAwareness Twitter feed.
The banner in the picture shown should read You Are Not Alone, instead it looks like, You Are Alone.
University of Maryland has a neat one page with the six essential steps for accessible online content. None of it is rocket science or geeky. This ready reference just has reminders to be a bit more thoughtful about how you go about it. The aim of the six steps is to give everyone equal access to information and services. It’s simple things such as colour contrast, alt-text for pictures, and appropriately placed links to other pages – not “click here”, for example. It’s a handy reference to print out and pin up at your desk. Good for designing online-learning and adding content to an organisation’s website.
The answer to “Is your site accessible?” is sometimes, “I haven’t been asked that before” or “I’m not sure I understand what you mean”. Some website managers will quote that they are WCAG2 compliant, but that doesn’t mean they know what it’s about. Some parts of the website design might be compliant, but some of the content might not be. So things like e-books, e-learning or customised apps could pose problems when it comes to accessibility for all. An article by Andreea Demirgian takes a look at these issues and more by using real examples of online chat conversations with web operators.
A related article, Do you see what I see… Accessibility challenge – CSS! gives instructions on how to find out if the CSS of the website is a barrier to accessibilty. A bit technical but gives insights into what web design should consider. The article is by Herin Hentry of the Reserve Bank of Australia.
Screen magnifiers are used by people who have low vision. It enlarges the text and images to a size where only part of the page or picture is visible at any one time. It is not the same as using the zoom function in the browser where the layout is changed to match the width of the screen. This means users have to scroll sideways to get the content of the page.
Because only a portion of the screen is displayed, the reader could miss instructions or drop down menus. How to Make Your Website Accessible to People Who Use a Screen Magnifier, has some good tips and a short video that shows what a screen magnifier does. The tips in the article are aimed at people in charge of websites. However, it is useful to see how it works and what happens when a site design doesn’t account for screen readers. It could help us think about the way we format documents and other information for websites.
It’s worth noting that there are around ten times as many people who use magnifiers and not screen readers, but accessibility guidelines seem to focus on readers. There is more on this topic from Axess Lab.
