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.
People with disability are often early adopters of new tech, but these new ideas can also come with unintended barriers to users. As we improve built environment accessibility, it is important we don’t fall into the same design traps with digital designs. Plug and Pray? A disability perspective on artificial intelligence, automated decision-making and emerging technologies is the title of a report by the European Disability Forum. There are two versions of this report:the standard full text and an Easy Readversion. The Easy Read version is great for non tech people. It is a great way to get your head around the many issues that need consideration without wading through lots of words.
The European Union funded a project to find out moreabout subtitling and how best to do it for immersive media. Media accessibility usually focuses on users with disability, but this group chose not to go that route. Instead they took a broader section of participants. One of their conclusions fits with other findings on universal design – make it part of the design from the beginning. The findings from this research have recommendations that are good for everyone. One key point is that creation and production processes should have testing that includes users with diverse capabilities. The title of the article is “From disabilities to capabilities: testing subtitles in immersive environments with end users“. With more content being delivered online and the rise of virtual reality and other types of media, this is an important contribution to understanding how best to present current media, as well as media that will be developed in the future.
From the Abstract: To illustrate this point and propose a new approach to user testing in Media Accessibility in which we would move from a disability to a capability model. Testing only with people with disability brings poorer results than testing with a broader range of people. This is because subtitles (closed captions) are not just for people are deaf or hard of hearing, but for everyone. This means they should be considered a mainstream feature of video and film production, not an add on feature. The study addresses issues with vision, colour, and being able to navigate digital services to find and use the subtitles.
Designers rarely design to exclude, but sometimes it just happens. Creating digital materials that are usable and accessible means many more people have access. Here is a book chapter that introduces readers to the ways people with disability use technology. It includes specific steps you can take and highlights the benefits of accessible design. Testing by people with disability is informative and should be included in the design process. As always, planning for accessibility from the start is always more cost-effective than fixing problems later. The title of the chapter is, “Designing for Inclusion: Ensuring Accessibility for People with Disabilities”. You will need institutional access to SpringerLink for a free read. Otherwise there is a payment option. The book is titled, “Consumer Informatics and Digital Health”.
With talk of Smart Cities, it is important for older people to be included in digital designs. Twenty-two industry built apps were evaluated in this open access study from Trinity College Dublin. Some were designed specifically for older people, and others for a broader target audience. Text re-sizing and zooming were the main issues. Overall, the apps did not meet accessibility principles of being perceivable, operable, or understandable for older people. The platforms supported accessibility settings, but for older people, finding these settings is a problem.
The article is titled, “Are Mobile Apps Usable and Accessible for Senior Citizens in Smart Cities?” It provides a comprehensive review and good conclusions. It is expected that more people will use mobile apps and computers to accomplish daily tasks and to access important information and services. This kind of study and ongoing research is therefore important.
Abstract. The population in cities is expected to exponentially grow by 2050, and so is the world population aged 65 and over. This has increased the efforts to improve citizens’ quality of life in urban areas by offering smarter and more efficient IT-based services in different domains such as health-care and transportation. Smart phones are key devices that provide a way for people to interact with the smart city services through their mobile applications (Apps). As the population is ageing and many services are now offered through mobile Apps, it is necessary to design accessible mobile interfaces that consider senior citizens’ needs. These needs are related to cognitive, perceptual, and psycho-motor changes that occur while ageing, which affect the way older people interact with a smart phone. Although a comprehensive set of design guidelines are suggested, there is no evaluation on how and to what extent they are considered during the mobile App design process. This paper evaluates the implementation of these guidelines in several industry-built Apps, which are either targeted at older people or critical city services Apps that may benefit older people, but are targeted at a broader audience.
Buried in this paper is a comparison chart of web design features for improved accessibility for older people. Older people have been singled out in this studybecause they are most at risk of being left out of the evolving digital world which includes e-health and internet based health information. The authors have combed through several guidelines and picked out the main elements that relate to this group because the WCAG 2.0 guidelines are deficient in this area. So they have turned to organisations such as the US-based AARP for the additional design features needed to help deal with motor and cognitive issues, and low vision. The article is in both English and Spanish.
The title is: Review of accessibility and usability guidelines for website design for the elderly people
ABSTRACT: By 2050, the growth of the elderly population in Colombia is estimated at 10% and thus a greater demand for special services (such as health services) for the elderly. This justifies the exploration of digital health content as an important source of information for this population. The accessibility and usability guidelines for website design – e.g., TAW and WACG – do not have special guidelines to mitigate the motor, cognitive or visual disabilities characteristic of aging, which become a barrier for this group to consult necessary information for administrative processes that involve health. This review of accessibility and usability guidelines is presented, facilitating the consumption of special contents and generating better interactions with such systems, which will lead to the construction of guidelines based on existing recommendations that allow the development of aspects related to interaction, legibility and usability in digital content for the elderly.
Creating access maps using data collected from individuals is part of a Google Maps project. But there is more to this than just knowing how to get from one place to another when you are a wheelchair user. What does it say about architecture and how we value citizens? Codes for architectural compliance do not include the human perspective of how people actually use places and spaces and relate to each other. This point is made in a philosophical article by Aimi Hamraie, “Mapping Access: Digital Humanities, Disability Justice, and Sociospatial Practice“. She covers the history of access mapping and uses a university campus as a case study, and challenges notions that access mapping is just a database of directional information. Hamraie claims she has developed a methodological tool for “excavating the politics of design embedded in the most banal features of everyday built environments”. A good read for anyone involved in mapping, GIS projects and the architecture of digital inclusion.
Note: This article uses academic language and concepts, but is thorough in discussing all aspects if the issues.
Older people are getting left behind in this digital world, especially if they are women and don’t live in a major city. The Conversation reports on the Australian Digital Inclusion Index(ADII) which measures which social groups benefit the most from digital connection, and which ones are being left behind. The score is based on access, affordability and ability to manage digital devices. While regional areas don’t have the same access to internet services as cities, there are programs that can help older people get internet-savvy. Telstra has its Tech Savvy Seniors program and the federal government has a Be Connected Program, and there is the Australian Seniors Computer Clubs Association. There are others listed in the article including an internet cafe set up by Umbrella Multicultural Community Care. The title of the article in The Conversation is, The digital divide: small, social programs can help get seniors online.
“Design is never neutral” is the title of an article by Adobe’s Khoi Vinh in the FastCompany newsletter. Is there is a down-side to making apps and websites too easy for children to use? The dilemma of course is that if young children can use these applications, most everyone else can too. But is this actually good? is the question:
“Habits are formed around the usability of a product; if an app or website makes it easy to complete a task, users are likely to do it more often than not. Usability advocates often treat this as an inherently good quality; by and large every business wants their products to be easier rather than more difficult to use. But as the aforementioned research suggests, it’s become clear that guilelessly encouraging longer, more frequent sessions isn’t necessarily better for kids.”
Artificial Intelligence (AI) can take captioning to another level claims Microsoft. AI for automatic speech recognition removes the need for a human captioner for lectures in universities, and elsewhere. The Microsoft AI blog articleand video below focuses on deaf students, but as more people take to captioning on their phones, it could make like easier for everyone. We already know that captioning helps all students by adding another layer of communication and this point is made in the article. The captioning is turned into transcripts and students have a reference to read after the lecture. They can also have the lecture automatically translated into several languages. This is a detailed article and covers automatic speech recognition, translations, and a growing demand for accessibility. This technology is not expected to take over from Auslan or ASL as they are languages in their own right. However, this is another example of how technology is helping humans by taking over from humans and bringing the advantages to more people.
