Tool for overcoming bias in design

A magnifying glass is held over a grid montage of human faces. Overcoming bias in design.Everyone has a bias. Our biases can lead us to fall into the traps that create unintended barriers or inconveniences for users. Recognising biases in our outlook is the key to countering them in design processes. Airbnb Design has a tool for overcoming bias in design. 

It’s a human trait to hold on to initial evidence more strongly than information we gather later on. Then we fit our interpretation of the world to match that initial evidence, regardless of what else we might learn as time passes. This can prevent the process of designing inclusively.

Airbnb Design partnered with journalists from News Deeply and came up with a toolkit for designers. Another Lens is a research tool for conscientious creatives. “We believe that both designers and journalists have the responsibility to shine a light on their bias by asking the right questions, seeking conflicting viewpoints, and expanding their lens to build inclusive, global solutions”.  

Three principles underpin the thinking process: balance your bias, consider the opposite and embrace a growth mindset. All good principles for universal design thinking. The website tool is simple to use, poses critical questions and provides the thinking behind it. 

It’s the way the brain processes things

A globe atlas of the world sits on a desk and lined up in front are small dolls representing different countriesDr Belina Liddell argues that culture may affect the way your brain processes everything. And that is important. The term “culture” is a very complex web of dynamic systems – beliefs, language and values, and also religion, socio-economic status and gender may play a part too.

Liddel explains how culture makes a difference to the way we not only perceive things intellectually, but visually as well. All this is from the emerging field of cultural neuroscience.  Now we have new acronym to deal with, WEIRD – Western, Educated, Industrialised, Rich, Democratic. The article also discusses refugee populations. See the ABC science website for more on this interesting article. 

 

Standard for accessible standards

Emily Steel pointing to the 11 Goals of the Guide on the presentation slide.All standards should ensure they meet the goals of the UN Convention on the Rights of Persons with Disabilities. So there is a Standard for developing Standards documents to be inclusive, accessible and universally designed. ISO Guide 71 shows how to do this. On day two of UD2021 Conference, Emily Steel explained how the international Standard for accessible Standards documents. 

The international standard has done all the thinking for us. The document guides standards committees as they write and update standards for their specific industry or profession. It is also useful for any committee developing guides or standards for accessibility and universal design. So, we don’t have to re-invent the wheel. 

The Guide’s use of the the term “accessibility” relates closely to universal design. “The extent to which products, systems, services, environments and facilities can be used by people from a population with the widest range of characteristics and capabilities to achieve a specified goal in a specified context of use”. 

ISO Guide 71 Accessibility Goals

The Guide has two main parts. The first describes user needs and 11 accessibility goals. These are similar to the 8 Goals of Universal Design. The second describes human characteristics and abilities, and design considerations. 

      1. Suitability for the widest range of users
      2. Conformity with user expectations
      3. Support for individualisation
      4. Approachability
      5. Perceivability
      6. Understandability
      7. Controllability
      8. Usability
      9. Error tolerance
      10. Equitable use
      11. Compatibility with other systems. 

Guide 71 was adapted by the European standards authority and is titled, CEN-CENELEC Guide 6. It is basically the same information. You can see a previous post about this document. 

There is also an Accessibility Masterlist by Gregg Vanderheiden. It’s a collaborative resource for understanding access features in digital applications. Also worth a look.

 

European universal design standard

Front cover of the Design for All standard.Universal design is a design thinking process so a universal design standard is a contradiction in terms. Standards are fixed where universal design is a continuous improvement process. However, where designers cannot grasp the concept of an inclusive thinking process, a set of design directions is needed. Hence a new European universal design standard for products, goods and services.

The standard sets out requirements and recommendations for extending the customer base for products and services. It’s for organisations that design and manufacture products and/or provide services. The aim is to ensure products and services are available to the widest range of users possible.

Diverse user needs, characteristics, capabilities and preferences area all covered. It is based on processes of user involvement and building on accessibility knowledge. The standard can also be used for complying with legislation and to advance corporate social responsibility. 

The standard was developed by Ireland’s National Disability Authority that houses the Centre for Excellence in Universal Design. The document has the title “design for all” which is a recognised European term, but notes that universal design, barrier-free-design and transgenerational design are the same thing. 

Design for All – Accessibility following a Design for All approach in products, goods and services – Extending the range of users can be purchased from the standards authority. 

There is a media release explaining a little more. 

Personas for digital technology

12 Faces representing the 12 personas.There’s nothing like asking potential users what they think of a new product. Even better if you involve them in the design process. But sometimes it’s not possible and designers resort to personas. This is often the case in digital technology. The Inclusive Design Toolkit has a suite of 12 personas representing a broad view of potential users. Each one has a story to tell about their lifestyle and their connection to technology.

Many factors affect digital exclusion: prior experience, competence, motivation and general attitude about technology. The personas highlight these factors to make it easier for designers to be inclusive. Each persona has a description of their lifestyle, competency with technology, and physical and sensory capabilities. 

The online resource is part of the Inclusive Design Toolkit with the option to download a PDF. You can take a deeper dive into the personas as a family set. This takes personas one step further by introducing family interactions. The Inclusive Design Toolkit also has an exclusion calculator that estimates the number of people unable to use a product or service. 

Cover of the book Inclusive design toolkitThe Inclusive Design Toolkit is based on thorough research over more than ten years. The personas were produced as part of a project to improve the inclusivity of railway journeys. 

The team wrote a conference paper about using personas for product development. They assessed the task of carrying a tray of food across a cafe, taking into account how using mobility aids restricts hand use. The title of the paper is, Evaluating inclusivity using quantitative personas. The full paper is available by request from ResearchGate. 

 

Playmobile helps with design translation

Playmobile figure in a bed with a doctor figure standing by.Doctors and architects speak different languages. That’s understandable – they’ve been to entirely different schools. We can get by in a foreign country with gestures. But when it comes to communicating detail we need a phrasebook. Similarly, architects and health professionals a similar tool – Playmobile. It helps with design translation. 

Using Playmobile figures and 3D printed beds and hospital equipment designers and medical staff can shape the spaces together. Not everyone can grasp the concept of spaces on a two-dimensional drawing. Likewise, designers do not have an intimate understanding of how clinics work. But everyone has played with toys. 

This is a great example of Universal Design for Learning (UDL). The short article on FastCompany doesn’t mention this specifically, but it follows the basic tenets: multiple means of engagement, representation and expression. 

This is not a new idea – Lego has been used in other situations.

Online hearing and vision simulators

Picture of a coffee machine in a cafeEver wondered what it is like for someone with hearing loss trying to be part of a conversation in a restaurant? Or wondered what it is like to try and read a transit map if you have glaucoma?  Now you can check this out using online hearing and vision simulators to get the idea of the way things sound and look.

The Inclusive Design Group at the University of Cambridge have come up with a hearing simulator that covers mild, moderate and severe hearing loss in five different settings: restaurant, classical music, rock music, a ringing phone, and a station platform announcement. Similarly, the vision simulator includes the main vision impairments including macular degeneration, glaucoma, cataracts, and diabetic retinopathy. 

You can also use their Exclusion Calculator for vision, hearing, thinking, dexterity, reach and stretch and locomotion, to see how many people might be excluded if not thought about in the early stages of design. You can set the calculator for multiple capacities, such as sight, hearing, thinking and locomotion – all of which are needed to negotiate public transport, for example. A very useful tool for any designer.

 

Colours for colour blindness

Title of the blog article using light blue and dark blue colours.Colour is often used in charts, maps and infographics, but what if you can’t see some colours? One in twelve men are colour blind, but not for all colours or the same colours. Infographics are becoming more popular as a means of explaining things. So choosing the best colours is to everyone’s advantage. Venngage website has an good guide and lots of tips on making charts more accessible. It shows the three types of colour blindness and compares them with normal vision. Different colour palettes are provided along with templates. The blog page includes links to other resources. Colour combinations to avoid include:

    • Red & green
    • Green & brown
    • Green & blue
    • Blue & gray
    • Blue & purple
    • Green & gray
    • Green & black

Most colour blind people can detect contrast, so as a last resort, if you must use these colours, make the contrast as strong as possible. Patterns and textures also work. The article is titled, How to use color blind friendly palettes to make your charts accessible.  Colour blindness is technically referred known as colour vision deficiency (CVD). 

Another resource for map colour by Tedora Zareva is useful too. You can also find out more about CVD or colour blindness from going to the National Eye Institute website

Which colour to use – A new standard?

There is a growing body of science on the topic of colour use and choice. On the second page of the International Ergonomics Association newsletter there is an item advising that in developing an international standard (ISO 24505) for colour use, accessibility needs to be considered. In four parts, the first part of the standard has been published for older people taking into account age-related changes in human colour vision. The remaining three are under development. Here is a snippet from the newsletter:

You understand me? Maybe

Front cover of the toolkit with three overlapping circles, bright pink, purple and turquoise.This toolkit about communicating with customers follows its own advice. The information is written in a straightforward way. Lots of graphics illustrate key points, and the information is very specific, such as when to write numbers as digits or as words. While the information might not be new to some, it serves as a good reviser of current practice. Designed for organisations but good for everyone.

The Customer Communications Toolkit for the Public Service – A Universal Design Approach has sections on written, verbal and digital communication. At 134 pages it is comprehensive. Each section has examples, tips, checklists and links to learn more. The intention of the toolkit is for public service planning, training and informing contractors. But of course, it works for anyone who is communicating with the public. 

Another great resource from Centre for Excellence in Universal Design in Ireland. Interesting to note that they have chosen colours for the cover and their logo that almost everyone can see – that includes people with colour vision deficiency.

Double Diamond: Tool for Design

Two red squares are placed on the diagonal with one corner touching each other. The left hand square has the words Discover and Define. The right hand square has Develop and Deliver. The diamond name comes from placing the squares in a diamond shape.Design isn’t just about tangible objects, it’s also about services and processes. This is where the Double Diamond Tool for Design comes to the fore. The Design Council devised the Double Diamond as a way of graphically explaining the design process. The two diamonds represent a process of exploring an issue and then taking focused action. The key elements of this model are:

Discover. The first diamond helps people understand, rather than simply assume, what the problem is. It involves speaking to and spending time with people who are affected by the issues.
Define. The insight gathered from the discovery phase can help you to define the challenge in a different way.
Develop. The second diamond encourages people to give different answers to the clearly defined problem, seeking inspiration from elsewhere and co-designing with a range of different people.
Deliver. Delivery involves testing out different solutions at small-scale, rejecting those that will not work and improving the ones that will.

The latest iteration of the Double Diamond is available in a PDF document and is explained on the website and a video. Several different design organisations have taken this model and made it their own. 

This model now has a fifteen year history. The Design Council has much more on their website about their Double Diamond and how to use it.  

What does inclusion actually mean?

Graphic of stick people in various poses with the caption, "Inclusiveness,, looking at everyone. What does inclusion mean?Kat Holmes found the origin of include was to “shut in”. Similarly, the origin of exclude was to “shut out”. Maybe “inclusion” is not the right word for describing the inclusion of everyone in products, places and things. So what does inclusion actually mean?

Holmes explains in the video below, that the topic of diversity is discussed as gender, sexual orientation, religious belief, ethnicity, and race. Disability is usually mentioned last in the list, if at all. “But it is the one category that transcends all other categories”, she says. “Abilities are constantly changing”. 

Holmes’ offers an alternative way for designers to consider diversity, and is based on her book, Mismatch: How Inclusion Shapes Design. An engaging talk for all upcoming designers in any field. And not just professional designers either. We all design things every day, so we all have a role to play. 

Editor’s Note: I discussed this issue in a 2009 paper. Inclusion requires those who are already included to invite into the group those who are excluded. Semantics are important. What we need is inclusiveness – that’s where inclusion has already happened and there are no exclusions. Inclusion is a futuristic concept – it’s something we are striving for. It it were achieved, no further discussion would be needed.
